Technology companies are starting to respond to a new Wi-Fi exploit affecting Vulnerability-related.DiscoverVulnerability all modern Wi-Fi networks using WPA or WPA2 encryption . The security vulnerabilities allow attackers to read Wi-Fi traffic between devices and wireless access points , and in some cases even modify it to inject malware into websites . Security researchers claim Vulnerability-related.DiscoverVulnerability devices running macOS , Windows , iOS , Android , and Linux will be affected Vulnerability-related.DiscoverVulnerability by the vulnerabilities . Microsoft says it has already fixed Vulnerability-related.PatchVulnerability the problem for customers running supported versions of Windows . “ We have released Vulnerability-related.PatchVulnerability a security update to address Vulnerability-related.PatchVulnerability this issue , ” says a Microsoft spokesperson in a statement to The Verge . “ Customers who apply Vulnerability-related.PatchVulnerability the update , or have automatic updates enabled , will be protected . We continue to encourage customers to turn on automatic updates to help ensure they are protected. ” Microsoft says the Windows updates released Vulnerability-related.PatchVulnerability on October 10th protect customers , and the company “ withheld disclosure Vulnerability-related.DiscoverVulnerability until other vendors could develop and release Vulnerability-related.PatchVulnerability updates. ” While it looks like Android and Linux devices are affected Vulnerability-related.DiscoverVulnerability by the worst part of the vulnerabilities , allowing attackers to manipulate websites , Google has promised Vulnerability-related.PatchVulnerability a fix for affected devices “ in the coming weeks. ” Google ’ s own Pixel devices will be the first to receive Vulnerability-related.PatchVulnerability fixes with security patch level of November 6 , 2017 , but most other handsets are still well behind even the latest updates . Security researchers claim Vulnerability-related.DiscoverVulnerability 41 percent of Android devices are vulnerable Vulnerability-related.DiscoverVulnerability to an “ exceptionally devastating ” variant of the Wi-Fi attack that involves manipulating traffic , and it will take time to patch Vulnerability-related.PatchVulnerability older devices . The Verge has reached out to a variety of Android phone makers to clarify when security patches will reach Vulnerability-related.PatchVulnerability handsets , and we ’ ll update you accordingly . At the time of writing , Apple has not yet clarified Vulnerability-related.DiscoverVulnerability whether the latest versions of macOS and iOS are vulnerable Vulnerability-related.DiscoverVulnerability . The Wi-Fi Alliance , a network of companies responsible for Wi-Fi , has responded to the disclosure Vulnerability-related.DiscoverVulnerability of the vulnerabilities . “ This issue can be resolved Vulnerability-related.PatchVulnerability through straightforward software updates , and the Wi-Fi industry , including major platform providers , has already started deploying Vulnerability-related.PatchVulnerability patches to Wi-Fi users , ” says a Wi-Fi Alliance spokesperson . “ Users can expect all their Wi-Fi devices , whether patched or unpatched Vulnerability-related.PatchVulnerability , to continue working well together. ” Apple also confirmed to both The Verge and AppleInsider that the vulnerability is patched Vulnerability-related.PatchVulnerability in a beta version of the current operating systems . The fix should go public Vulnerability-related.PatchVulnerability in a few weeks , so iOS and macOS devices are n't in the clear just yet . AppleInsider also reports that AirPort hardware , including the Time Machine , AirPort Extreme base station , and AirPort Express do not have a patch . The publication 's source also was n't sure if one was in the works .

THAT UN-PATCHABLE FLAW in the Nintendo Switch ? Yeah , the Japanese gaming firm has only gone and fixed Vulnerability-related.PatchVulnerability it , according to console hacker Michael . Michael , who goes by the Twitter handle @ SciresM , tweeted that it 's bad news for console hackers and Nintendo is pushing out Vulnerability-related.PatchVulnerability new console models with a fix that stops tech-savvy folks from messing around with the software that the hybrid games console can boot with . The flaw was thought to be un-patchable as it affected Vulnerability-related.DiscoverVulnerability the Nvidia Tegra X1 chip that sits at the heart of the console . But Nintendo hates piracy more than most games firms , and as such , will release new versions of the Switch that do n't have the silicon-level flaw in them . The patch involves using a system called ‘ iPatches ' which updates Vulnerability-related.PatchVulnerability parts of the code applying to the Tegra X1 's fuses which plugs Vulnerability-related.PatchVulnerability the boot hacking exploit . Current consoles out in the wild will still be vulnerable Vulnerability-related.DiscoverVulnerability due to the patch needing to be applied Vulnerability-related.PatchVulnerability at a hardware level , but new models wo n't be susceptible to the hack . But there 's a bit of an odd situation here , as the new consoles will come running 4.1.0 versions of the Switch firmware ; the latest Switch firmware is 5.1.0 . So while the new Switchers will come off the production line immune to the Tegra X1 exploit , they will still be vulnerable Vulnerability-related.DiscoverVulnerability to other hacking techniques . With this in mind , Michael advises that people keen to crack into their Switch consoles should not apply Vulnerability-related.PatchVulnerability any updates , as the older version of the console 's firmware is the easier it 's to hack . So while the un-patchable flaw may have been fixed Vulnerability-related.PatchVulnerability the current iteration of the Switch is still no un-hackable . Not that hacking the Switch is a good idea if you want to run pirated games , as Nintendo takes a very dim view of that and cracks down so hard on pirates that it 'll permanently ban any console caught with bootlegged software from its online network . With The Legend of Zelda : Breath of the Wild and Mario Odyssey alone there are tens of hours of gaming to be had on the Switch . let along all the stuff that 's incoming and the suite of indie titles the console supports . So if you desperately need to hack the Switch to play more games , perhaps it 's time to take a break from gaming and go out into the sun ; we hear the UK is lovely at the moment .

Oracle has released Vulnerability-related.PatchVulnerability a critical patch update addressing Vulnerability-related.PatchVulnerability more than 300 vulnerabilities across several of its products – including one flaw with a CVSS 3.0 score of 10 that could allow the takeover of the company ’ s software package , Oracle GoldenGate . Of the 301 security flaws that were fixed Vulnerability-related.PatchVulnerability in this month ’ s Oracle patch , 45 had a severity rating of 9.8 on the CVSS scale . “ Due to the threat posed by a successful attack , Oracle strongly recommends that customers apply Vulnerability-related.PatchVulnerability Critical Patch Update fixes as soon as possible , ” the company said in its Tuesday advisory . The highest-severity flaw ( CVE-2018-2913 ) lies in Vulnerability-related.DiscoverVulnerability the Monitoring Manager component of Oracle GoldenGate , which is the company ’ s comprehensive software package that allows data to be replicated in heterogeneous data environments . According to the National Vulnerability Database , the glitch is an easily exploitable vulnerability that allows unauthenticated attacker with network access via the TCP protocol to compromise Oracle GoldenGate . The flaw was discovered Vulnerability-related.DiscoverVulnerability by Jacob Baines , a researcher with Tenable . “ CVE-2018-2913 is a stack buffer overflow in GoldenGate Manager , ” Baines told Vulnerability-related.DiscoverVulnerability Threatpost . “ The Manager listens on port 7809 where it accepts GoldenGate Software Command Interface ( GGSCI ) commands . Tenable found that a remote unauthenticated attacker can trigger a stack buffer overflow by sending a GGSCI command that is longer than expected. ” The attack is not complex and a bad actor could be remote and unauthenticated . Making matters worse , an attacker could compromise other products after initially attacking GoldenGate , the advisory warned . “ While the vulnerability is in Oracle GoldenGate , attacks may significantly impact additional products , ” the note said Vulnerability-related.DiscoverVulnerability . “ Successful attacks of this vulnerability can result in takeover of Oracle GoldenGate. ” The flaw impacts Vulnerability-related.DiscoverVulnerability versions 12.1.2.1.0 , 12.2.0.2.0 , and 12.3.0.1.0 in Oracle GoldenGate . Currently no working exploits for the flaw have been discovered Vulnerability-related.DiscoverVulnerability in the wild , according to the release . It should be noted that For Linux and Windows platforms , the flaw ’ s CVSS score is 9.0 because the access complexity is lower ( only rated high , not critical ) ; while for all other platforms , the CVSS score is a critical 10 . Two other flaws were also discovered Vulnerability-related.DiscoverVulnerability in Oracle GoldenGate ( CVE-2018-2912 and CVE-2018-2914 ) , with ratings of 7.5 on the CVSS scale ; those vulnerabilities weren ’ t nearly as severe . “ All of these vulnerabilities may be remotely exploitable without authentication , i.e. , may be exploited Vulnerability-related.DiscoverVulnerability over a network without requiring user credentials . ”

A critical vulnerability in open source automation tool Jenkins could allow permission checks to be bypassed through the use of specially-crafted URLs . Jenkins uses the Stapler web framework for HTTP request handling , which uses reflection to dispatch incoming web requests to controller code . This means that any public methods that start with get and include string and integer parameters are exposed to the web server . Because this is a common naming convention , this has led to multiple internal Jenkins methods being inadvertently exposed . The precise impact of this isn ’ t clear . The advisory notes that code execution could be a possible outcome – though on closer inspection , this seems to be a worst-case scenario . “ To clarify , the vulnerability we addressed Vulnerability-related.PatchVulnerability had nothing to do with arbitrary code execution , but was rather an issue discovered Vulnerability-related.DiscoverVulnerability by the Jenkins security team that allowed a small subset of existing Jenkins code to be invoked by a remote client , ” Daniel Beck , Jenkins security officer , told The Daily Swig in an email . “ While the known impact is pretty limited , we felt that the layer at which the vulnerability existed , and its potential warranted a higher score. ” These potential attacks include unauthenticated users being able to invalidate sessions when running with the built-in server , and users with overall/read permissions being able to create new user objects in memory . The advisory reads : “ Given the vast potential attack surface , we fully expect other attacks , that we are not currently aware of , to be possible on Jenkins releases that do not have this fix applied Vulnerability-related.PatchVulnerability . “ This is reflected in the high score we assigned Vulnerability-related.DiscoverVulnerability to this issue , rather than limiting the score to the impact through known issues. ” Beck added : “ Jenkins users should always keep their instances up to date . In this case , we released Vulnerability-related.PatchVulnerability updates for two LTS lines simultaneously for the first time , so admins could apply Vulnerability-related.PatchVulnerability the update without having to go through a major version jump . “ We strive to fix Vulnerability-related.PatchVulnerability all security vulnerabilities in Jenkins and plugins in a timely manner. ” Reflection is also used by Apache Struts , via the OGNL library . Struts has suffered Vulnerability-related.DiscoverVulnerability a number of serious security flaws in recent years . In 2017 , a vulnerability in the framework was exploited Vulnerability-related.DiscoverVulnerability to expose Attack.Databreach the details of up to 148 million Equifax customers . Another flaw , revealed Vulnerability-related.DiscoverVulnerability in August 2018 , could lead to remote code execution . These issues underline the dangers of using reflection with untrusted data , and application architects would do well to avoid this unsafe practice .

Oracle released Vulnerability-related.PatchVulnerability its latest Critical Patch Update on July 18 , fixing Vulnerability-related.PatchVulnerability 334 vulnerabilities across the company 's product portfolio . The company rated 61 of the vulnerabilities as having critical impact . Among the products patched Vulnerability-related.PatchVulnerability by Oracle are Oracle Database Server , Oracle Global Lifecycle Management , Oracle Fusion Middleware , Oracle E-Business Suite , Oracle PeopleSoft , Oracle Siebel CRM , Oracle Industry Applications , Oracle Java SE , Oracle Virtualization , Oracle MySQL and Oracle Sun Systems Products Suite . While there are issues of varying severity in the update , Oracle is blaming third-party components as being the cause of the majority of the critical issues . `` It is fair to note that bugs in third-party components make up a disproportionate amount of severe vulnerabilities in this Critical Patch Update , '' Eric Maurice , director of security assurance at Oracle , wrote in a blog post . `` 90 percent of the critical vulnerabilities addressed Vulnerability-related.PatchVulnerability in this Critical Patch Update are for non-Oracle CVEs . '' Of the 334 issues fixed Vulnerability-related.PatchVulnerability in the July Critical Patch Update , 37 percent were for third-party components included in Oracle product distributions . While many flaws were from third-party libraries , there were also flaws in Oracle 's own development efforts . Oracle 's namesake database was patched Vulnerability-related.PatchVulnerability for three issues , one of which is remotely exploitable without user authentication . Oracle 's Financial Services application received Vulnerability-related.PatchVulnerability the highest total number of patches at 56 , with 21 identified as being remotely exploitable without user authentication . Oracle 's Fusion Middleware , on the other hand , got Vulnerability-related.PatchVulnerability 44 new security fixes , with 38 of them rated as being critical . Oracle Enterprise Manager Products were patched Vulnerability-related.PatchVulnerability for 16 issues , all of which are remotely exploitable without authentication . Looking at flaws in Java , Oracle 's July CPU provides Vulnerability-related.PatchVulnerability eight security fixes , though organizations likely need to be cautious when applying Vulnerability-related.PatchVulnerability the patches , as certain functionality has been removed . `` Several actions taken to fix Vulnerability-related.PatchVulnerability Java SE vulnerabilities in the July CPU are likely to break the functionality of certain applications , '' security firm Waratek warned in an advisory . `` Application owners who apply Vulnerability-related.PatchVulnerability binary patches should be extremely cautious and thoroughly test their applications before putting Vulnerability-related.PatchVulnerability patches into production . '' The reason why the Oracle fixes could break application functionality is because Oracle has decided to remove multiple vulnerable components from its Java Development Kit ( JDK ) . At 334 fixed flaws , the July update is larger than last Critical Patch Update released Vulnerability-related.PatchVulnerability on Jan 15 , which provided Vulnerability-related.PatchVulnerability patches for 237 flaws . While the number of patches issues has grown , Matias Mevied , Oracle security researcher at Onapsis , commented that Oracle is working in the right way , fixing Vulnerability-related.PatchVulnerability the reported vulnerabilities and is getting faster every year . `` Unfortunately , based in our experience , the missing part is that the companies still do n't implement the patches as soon as they should be , '' Mevied told eWEEK .

Onapsis discovered Vulnerability-related.DiscoverVulnerability several high risk vulnerabilities affecting Vulnerability-related.DiscoverVulnerability SAP HANA platforms . If exploited Vulnerability-related.DiscoverVulnerability , these vulnerabilities would allow an attacker , whether inside or outside the organization , to take full control of the SAP HANA platform remotely , without the need of a username and password . “ This level of access would allow an attacker to perform any action Attack.Databreach over the business information and processes supported by HANA , including creating , stealing Attack.Databreach , altering , and/or deleting sensitive information . If these vulnerabilities are exploited Vulnerability-related.DiscoverVulnerability , organizations may face severe business consequences , ” said Sebastian Bortnik , Head of Research , Onapsis . The vulnerabilities affect Vulnerability-related.DiscoverVulnerability a specific SAP HANA component named SAP HANA User Self Service , which is not enabled by default . The following list details the affected HANA 2 and HANA versions : “ We hope organizations will use this threat intelligence to assess their systems and confirm that they are not currently using this component , and therefore are not affected by these risks . Even if the service is not enabled , we still recommend that these organizations apply Vulnerability-related.PatchVulnerability the patches in case a change is made to the system in the future , ” continued Bortnik . Onapsis Research Labs originally discovered Vulnerability-related.DiscoverVulnerability the vulnerabilities on the newly released SAP HANA 2 platform , but after additional analysis realized that several older versions were vulnerable Vulnerability-related.DiscoverVulnerability as well . Based on this assessment , it was identified Vulnerability-related.DiscoverVulnerability that the vulnerabilities had been present Vulnerability-related.DiscoverVulnerability in HANA for almost two and a half years , when the User Self Service component was first released . This greatly increases the likelihood that these vulnerabilities have been discovered Vulnerability-related.DiscoverVulnerability by attackers to break into organization ’ s SAP systems . Onapsis worked closely with SAP ’ s Product Security & Engineering teams to help them develop Vulnerability-related.PatchVulnerability the security patches . SAP is releasing the first ever patch for SAP HANA 2 . In this case , default installations are affected and an attacker can elevate privileges if exploited

I get an alert on my phone from a news feed around critical vulnerability patches being released Vulnerability-related.PatchVulnerability by SAP . Before I discuss Vulnerability-related.DiscoverVulnerability the details of the latest two SAP HANA vulnerabilities and the potential business impact , let me take a moment to reiterate Vulnerability-related.DiscoverVulnerability that this is the most vulnerable period for any SAP customer with this critical flaw in their IT landscape . This period , which I call “ Hackers Busy Cracking , ” started this morning and will not end until affected clients across the globe apply Vulnerability-related.PatchVulnerability the patch from SAP . Onapsis Security Research Lab discovered Vulnerability-related.DiscoverVulnerability these vulnerabilities but hasn ’ t published technical details yet . We do know Vulnerability-related.DiscoverVulnerability that the vulnerability is in the user self-service functionality provided by SAP HANA and has been present Vulnerability-related.DiscoverVulnerability since SPS09 of SAP HANA , which was released in 2014 . As the name suggests , the user self-service functionality enables users to perform maintenance and support activities for their accounts and for new users to register the accounts . For this functionality to be useful , it must be accessible from wherever the user population is , be it on internal or external networks . The second critical vulnerability revolves around Vulnerability-related.DiscoverVulnerability session fixation , which can allow an attacker to elevate privileges by impersonating another user in the system . The SAP HANA 2.0 SPS 00 version is affected by Vulnerability-related.DiscoverVulnerability this vulnerability . User self-service is a good example of technology that is a double-edged sword . It cuts costs associated with supporting a large user population and reduces the time taken to correct user issues , thus ensuring individuals spend more time as productive users . However , any unattended mechanism that allows modification of accounts without human intervention will always be an attractive target . According to the Onapsis report Vulnerability-related.DiscoverVulnerability , a combination of vulnerabilities can allow an attacker with remote access to the user self-service functionality to edit any account on the system , including activating previously deactivated accounts . The natural target for this attack would be the SYSTEM account present in all HANA deployments . The potential business impact of an attacker with access to the SYSTEM account is extraordinary . I strongly urge all SAP HANA customers to check their HANA version levels and make immediate plans to prioritize these updates . SAP customers who have already deployed active threat protection ( ATP ) controls or third-party products are one step ahead of zero-day threats . For the rest , look to invest in an active threat monitoring and detection solution — meaning a SAP-specific threat vector detection solution .

Researchers from security firm ERPScan have disclosed Vulnerability-related.DiscoverVulnerability a vulnerability in the SAP GUI application which it has described as Vulnerability-related.DiscoverVulnerability perhaps the most dangerous SAP issue since 2011 , as it affects not only every SAP customer but also every user . The vulnerability allows an attacker to make all endpoints with compromised SAP GUI clients automatically install malware that locks their computers when an SAP user logs in to the system . When the user next logs into the SAP GUI application , the malicious software will run and prevent them from logging on to SAP Server . Firstly , in this case , patching process is especially laborious and time-consuming , as the vulnerability affects Vulnerability-related.DiscoverVulnerability client side , so an SAP administrator has to apply Vulnerability-related.PatchVulnerability the patch on every endpoint with SAP GUI in a company and a typical enterprise has thousands of them , ” said Vulnerability-related.DiscoverVulnerability Vahagn Vardanyan , senior security researcher , ERPScan . The vulnerability was patched Vulnerability-related.PatchVulnerability by SAP with a fix as part of its March Security Note 2407616 . An SAP spokesperson confirmed that a SAP GUI vulnerability was fixed Vulnerability-related.PatchVulnerability in the March Patch Day , with further details available via this blog post . “ It has a priority of High , based on CVSS rating of 8.0 ( but not Very High ) . We have no information or evidence of this vulnerability being exploited Vulnerability-related.DiscoverVulnerability at a customer but advise all customers to patch Vulnerability-related.PatchVulnerability their infrastructure immediately . Customers are required to apply Vulnerability-related.PatchVulnerability the SAP GUI patch released Vulnerability-related.PatchVulnerability on their landscape using their standard client software distribution and update tools ( which they would have in place for end-user software licensed from other vendors as well ) , ” the spokesperson said . Pingback : SAP GUI vulnerability “ most dangerous ” since 201

This is a serious violation of the security barrier enforced by the hypervisor and poses a particular threat to multi-tenant data centers where the customers ' virtualized servers share the same underlying hardware . The open-source Xen hypervisor is used by cloud computing providers and virtual private server hosting companies , as well as by security-oriented operating systems like Qubes OS . The new vulnerability affects Vulnerability-related.DiscoverVulnerability Xen 4.8.x , 4.7.x , 4.6.x , 4.5.x , and 4.4.x and has existed in the Xen code base for over four years . It was unintentionally introduced Vulnerability-related.DiscoverVulnerability in December 2012 as part of a fix for a different issue . The Xen project released Vulnerability-related.PatchVulnerability a patch Tuesday that can be applied manually to vulnerable deployments . The good news is that the vulnerability can only be exploited Vulnerability-related.DiscoverVulnerability from 64-bit paravirtualized guest operating systems . Xen supports two types of virtual machines : Hardware Virtual Machines ( HVMs ) , which use hardware-assisted virtualization , and paravirtualized ( PV ) VMs that use software-based virtualization . Based on whether they use PV VMs , Xen users might be affected or not . For example , Amazon Web Services said in Vulnerability-related.DiscoverVulnerability an advisory that its customers ' data and instances were not affected Vulnerability-related.DiscoverVulnerability by this vulnerability and no customer action is required . Meanwhile , virtual private server provider Linode had to reboot some of its legacy Xen servers in order to apply Vulnerability-related.PatchVulnerability the fix . Qubes OS , an operating system that uses Xen to isolate applications inside virtual machines , also put out an advisory warning Vulnerability-related.DiscoverVulnerability that an attacker who exploits another vulnerability , for example inside a browser , can exploit Vulnerability-related.DiscoverVulnerability this Xen issue to compromise the whole Qubes system . The Qubes developers have released Vulnerability-related.PatchVulnerability a patched Xen package for Qubes 3.1 & 3.2 and reiterated their intention to stop using paravirtualization altogether in the upcoming Qubes 4.0 . Vulnerabilities that allow breaking the isolation layer of virtual machines can be very valuable for attackers .

Cyber security researchers on Monday pointed to code in a "ransomware" attack Attack.Ransom that could indicate a link to North Korea . Symantec and Kaspersky Lab each cited code that was previously used by a hacker collective known as the Lazarus Group , which was behind the high-profile 2014 hack of Sony that was also blamed on North Korea . But the security firms cautioned that it is too early to make any definitive conclusions , in part because the code could have been merely copied by someone else for use in the current event . The effects of the ransomware attack Attack.Ransom appeared to ease Monday , although thousands more computers , mostly in Asia , were hit Attack.Ransom as people signed in at work for the first time since the infections spread to 150 countries late last week . Health officials in Britain , where surgeries and doctors ' appointments in its national health care system had been severely impacted Friday , were still having problems Monday . But health minister Jeremy Hunt said it was `` encouraging '' that a second wave of attacks had not materialized . He said `` the level of criminal activity is at the lower end of the range that we had anticipated . '' In the United States , Tom Bossert , a homeland security adviser to President Donald Trump , told the ABC television network the global cybersecurity attack is something that `` for right now , we 've got under control . '' He told reporters at the White House that `` less than $ 70,000 '' has been paid as ransom Attack.Ransom to those carrying out the attacks . He urged all computer users to make sure they install Vulnerability-related.PatchVulnerability software patches to protect themselves against further cyberattacks . In the television interview , Bossert described the malware that paralyzed 200,000 computers running factories , banks , government agencies , hospitals and transportation systems across the globe as an `` extremely serious threat . '' Cybersecurity experts say the hackers behind the `` WannaCry '' ransomware , who demanded Attack.Ransom $ 300 payments Attack.Ransom to decrypt files locked by the malware , used a vulnerability that came from U.S. government documents leaked online . The attacks exploited Vulnerability-related.DiscoverVulnerability known vulnerabilities in older Microsoft computer operating systems . During the weekend , Microsoft president Brad Smith said the clandestine U.S. National Security Agency had developed the code used in the attack . Bossert said `` criminals , '' not the U.S. government , are responsible for the attacks . Like Bossert , experts believe Microsoft 's security patch released Vulnerability-related.PatchVulnerability in March should protect networks if companies and individual users install it . Russian President Vladimir Putin said his country had nothing to do with the attack and cited the Microsoft statement blaming the NSA for causing the worldwide cyberattack . `` A genie let out of a bottle of this kind , especially created by secret services , can then cause damage to its authors and creators , '' Putin said while attending an international summit in Beijing . He said that while there was `` no significant damage '' to Russian institutions from the cyberattack , the incident was `` worrisome . '' `` There is nothing good in this and calls for concern , '' he said . Even though there appeared to be a diminished number of attacks Monday , computer outages still affected segments of life across the globe , especially in Asia , where Friday 's attacks occurred after business hours . China China said 29,000 institutions had been affected , along with hundreds of thousands of devices . Japan 's computer emergency response team said 2,000 computers at 600 locations were affected there . Universities and other educational institutions appeared to be the hardest hit in China . China 's Xinhua News Agency said railway stations , mail delivery , gas stations , hospitals , office buildings , shopping malls and government services also were affected . Elsewhere , Britain said seven of the 47 trusts that run its national health care system were still affected , with some surgeries and outpatient appointments canceled as a result . In France , auto manufacturer Renault said one of its plants that employs 3,500 workers stayed shut Monday as technicians dealt with the aftermath of the Friday attacks . Security patches Computer security experts have assured individual computer users who have kept their operating systems updated that they are relatively safe , but urged companies and governments to make sure they apply Vulnerability-related.PatchVulnerability security patches or upgrade Vulnerability-related.PatchVulnerability to newer systems . They advised those whose networks have been effectively shut down by the ransomware attack Attack.Ransom not to make the payment demanded Attack.Ransom , the equivalent of $ 300 , paid Attack.Ransom in the digital currency bitcoin . However , the authors of the "WannaCry" ransomware attack Attack.Ransom told their victims the amount they must pay Attack.Ransom will double if they do not comply within three days of the original infection , by Monday in most cases . The hackers warned that they will delete all files on infected systems if no payment Attack.Ransom is received within seven days .

Adobe has patched Vulnerability-related.PatchVulnerability two critical flaws in Acrobat and Reader that warrant urgent attention . Officially , Adobe patches Vulnerability-related.PatchVulnerability security vulnerabilities around the middle of each month to coordinate with Microsoft ’ s Patch Tuesday , but recently it ’ s become almost routine for the company to issue Vulnerability-related.PatchVulnerability out-of-band updates in between . APSB19-02 , the first of such updates to reach customers in the new year , addresses Vulnerability-related.PatchVulnerability critical flaws with a priority rating of ‘ 2 ’ . That means that the flaw is potentially serious , but Adobe hasn ’ t detected Vulnerability-related.DiscoverVulnerability any real-world exploits ( the latter would entail issuing Vulnerability-related.PatchVulnerability an ‘ emergency ’ patch with a ‘ 1 ’ rating ) . The first flaw , identified Vulnerability-related.DiscoverVulnerability as CVE-2018-16011 , is described Vulnerability-related.DiscoverVulnerability by Adobe as a use-after-free bug that could be exploited Vulnerability-related.DiscoverVulnerability using a maliciously crafted PDF to take control of a target system with their malware of choice . The second , CVE-2018-16018 ( replacing CVE-2018-19725 ) , is a security bypass targeting JavaScript API restrictions on Adobe Reader DC and seems to have been in the works since before Christmas , affecting Vulnerability-related.DiscoverVulnerability all versions of Window and macOS Acrobat DC/Reader 2019.010.20064 and earlier , the fix in both cases is to update Vulnerability-related.PatchVulnerability to 2019.010.20069 . For the legacy Acrobat/Reader 2017 2017.011.30110 and Acrobat/Reader DC 2015 2015.006.30461 , the updates take those to 2017.011.30113 and 2015.006.30464 respectively . As critical flaws with a ‘ 2 ’ rating , there is a suggested 30-day window within which to apply Vulnerability-related.PatchVulnerability the updates , but it ’ s worth bearing in mind that a new round of patches will likely be offered Vulnerability-related.PatchVulnerability for Adobe products tomorrow as part of Patch Tuesday . In December ’ s Patch Tuesday , Adobe released Vulnerability-related.PatchVulnerability a not inconsiderable 87 patches , including 39 rated critical . Only days before , Adobe issued Vulnerability-related.PatchVulnerability an emergency Flash patch for a zero-day vulnerability that was being exploited Vulnerability-related.DiscoverVulnerability , while in November Flash received Vulnerability-related.PatchVulnerability a separate patch for one whose exploitation was believed to be imminent .
