in March . Ransomware is no longer just a nuisance . Now it 's quite literally a matter of life and death . A massive ransomware attackAttack.Ransombeing labeled as `` WannaCryAttack.Ransom`` has been reported around the world and is responsible for shutting down hospitals in the United Kingdom and encrypting files at Spanish telecom firm Telefonica . The WannaCry attackAttack.Ransomis not a zero-day flaw , but rather is based on an exploit that Microsoft patchedVulnerability-related.PatchVulnerabilitywith its MS17-010 advisory on March 14 in the SMB Server . However , Microsoft did not highlightVulnerability-related.DiscoverVulnerabilitythe SMB flaw until April 14 , when a hacker group known as the Shadow Brokers releasedVulnerability-related.DiscoverVulnerabilitya set of exploits , allegedly stolenAttack.Databreachfrom the U.S.National Security Agency . SMB , or Server Message Block , is a critical protocol used by Windows to enable file and folder sharing . It 's also the protocol that today 's WannaCry attackAttack.Ransomis exploiting to rapidly spread from one host to the next around the world , literally at the speed of light . The attack is what is known as a worm , `` slithering '' from one host to the next on connected networks . Among the first large organizations to be impacted by WannaCry is The National Health Service in the UK , which has publicly confirmed that it was attackedAttack.Ransomby the Wan na Decryptor. `` This attackAttack.Ransomwas not specifically targeted at the NHS and is affecting organisations from across a range of sectors , '' the NHS stated . `` At this stage we do not have any evidence that patient data has been accessedAttack.Databreach. '' Security firm Kaspersky Lab reported that by 2:30 p.m . ET May 12 it had already seen more than 45,000 WannaCry attacksAttack.Ransomin 74 countries . While the ransomware attackAttack.Ransomis making use of the SMB vulnerability to spread , the encryption of files is done by the Wanna Decryptor attackAttack.Ransomthat seeks out all files on a victim 's network . Once the ransomware has completed encrypting files , victims are presented with a screen demanding a ransomAttack.Ransom. Initially , the ransom requestedAttack.Ransomwas reported to be $ 300 worth of Bitcoin , according to Kaspersky Lab . `` Many of your documents , photos , videos , databases and other files are no longer accessible because they have been encrypted , '' the ransom note states . `` Maybe you are busy looking for a way to recover your files , but do not waste your time . Nobody can recover your files without our decryption service . '' It 's not clear who the original source of the global WannaCry attacksAttack.Ransomis at this point , or even if it 's a single threat actor or multiple actors . What is clear is that despite the fact that a software patch has been availableVulnerability-related.PatchVulnerabilitysince March for the SMB flaws , WannaCry is using tens of thousands of organizations that did n't patchVulnerability-related.PatchVulnerability.
Since last Friday , over 200,000 victims in 150 countries have been hitAttack.Ransomby a massive , international ransomware cyberattackAttack.Ransomcalled WannaCry . Ransomware is a type of malware that works by seizing control of and blocking access to a computer ’ s files , programs , and operations . Users are then informed that they must payAttack.Ransoma certain amount in order to regain access to their files , with the threat of permanently losing all of their data if they choose not to payAttack.Ransom. In the WannaCry attackAttack.Ransom, users were given three days to make the paymentAttack.Ransombefore the fee increased , and seven days before the files would be lost forever . The massive scope and potential financial impact of the WannaCry attackAttack.Ransomhas understandably caused a lot of panic , and companies and individuals alike have been rushing to protect their devices . However , this frenzy has opened up new damaging routes for fraud . One of these attack routes is through mobile applications that have been found on third-party application stores . There are various mobile applications advertising that they can be used to protect users from the WannaCry ransomware . However , our analysts found that some of these apps contained adware meant to infect the devices they are downloaded onto . Rather than protecting users ’ devices , they are causing them harm . The adware found is classified as Adware.mobidash , which is a module that attackers used to include into Android games and apps and monetize them . This adware has the capability to load webpages with ads , show other messages in the status bar , and modify the DNS server . This is quite dangerous as the real risk lies in the fact that the end user ’ s device is performing unwanted activity without their authorization . To hide this dangerous behavior , the adware doesn ’ t start to perform its malicious activity immediately ; instead , it lies latent in the device before activating after a short period of time . We have blogged a lot about digital trust , fake news , and all sorts of tricksAttack.Phishingthat criminals use to get the attention of consumers to get them to click on a link . Yet we continue to be amazed by how sophisticated the manipulation of the human factor has become . It will only be a matter of time until we see the WannaCry malware expand further to trickAttack.Phishingend users into installingVulnerability-related.PatchVulnerabilitya patch that allegedly prevents the new massive ransomware attackAttack.Ransom. However , this time it will not be a patch , but a new version or variant of a financially motivated malware .

Cyber security experts reveal they have found a second massive computer virus which has affected hundreds of thousands of computers world-wide , like the WannaCry cyber attackAttack.Ransomlast week , has affected hundreds of thousands of computers world-wide and may have North Korean origins . This second global hack exploits the same Microsoft vulnerabilities as the WannaCry attackAttack.Ransomand it is estimated to have infected more than 200,000 computers . The full scale of this attack , however , is still being determined due to the fact the attack is on-going . Preliminary analysis by California-based cyber security firm Proofpoint , which revealed the existence of this more subtle virus , suggests “ that this attack may be larger in scale than WannaCry ” , the company said in an online statement . Unlike last week ’ s attack which infected more than 300,000 computers since last Friday , this second cyber attack is thought to have begun either in late April or early May , but it had avoided being detected until recently , said Proofpoint researchers . Computers infected by this second virus do not have their functions altered , nor are their files encrypted . Instead , they manufacture digital currency . Proofpoint said the virus installs the Adylkuzz currency “ miner ” – a sort of malware which hijacks a computer ’ s processing power to solve complex math problems and earn digital money . There exists several different kinds of online currencies , the most famous being Bitcoin . But this second attack is designed to generate a newer form of digital cash called Monero . Monero offers enhanced anonymity features and is the currency of darknet market place AlphaBay . Experts also believe the currency has been pursued by North Korea-linked hacker groups . Proofpoint estimates this relatively unobtrusive computer virus generated more than a million euro – much more than what the WannaCry hackers extortedAttack.Ransomfrom their ransomware attackAttack.Ransom. A North Korean hacker group called the Lazarus Group is thought to be behind last week ’ s massive ransomware attackAttack.Ransomand now it is thought a segment of this hacker group may be behind the currency mining attack . Kapersky Lab , a cyber security firm , said a segment of the Lazarus group had installed software on a European server in early April to mine Monero currency , said Reuters . Proofpoint executive Ryan Kalember , speaking to Reuters , said he believes these two attacks are “ more than coincidence ” . “ It ’ s a really strong overlap ” , he told Reuters . “ It ’ s not like you see Monero miners all over the world . ”
