Senate Democrats are still rebuilding their computer system after hackers demanded a ransom Attack.Ransom earlier this month to unlock the network . The state legislators ' offices continue to operate via a combination of cell phones and laptops , some personal and some provided by the caucus . In the last two weeks , email service was also restored . On Monday , Senate Minority Leader Jay Costa said Microsoft technicians would begin going around to strip down and rebuild every computer with the goal of having everything restored in the next several days . `` [ They are ] working to rebuild our network so we 're all operating off one system , '' the Allegheny County Democrat said . `` We 're rebooting that very soon . '' Costa said he can not comment on the ongoing investigation or the exact dollar amount demanded Attack.Ransom by the hackers . The caucus has not and will not pay the ransom Attack.Ransom , he said . `` For people who do pay the ransom Attack.Ransom , the likelihood they 'll get the codes they need to undo the encryption is much lower than people talk about , '' he said . `` And there are a number of times it 's happened you do n't hear about . '' Hackers who launch such attacks lock their targets out of their data in an effort to extract a ransom Attack.Ransom for its return . The security firm SonicWall estimated 638 million ransomware attacks Attack.Ransom that cost $ 209 million last year , more than 167 times the 3.8 million attacks Attack.Ransom recorded in 2015 .

Austrian police arrested a 19-year-old teenager from Linz for infecting the network of a local company with the Philadelphia ransomware . The incident in question took place last year and targeted an unnamed company based in Linz . The attacker locked the company 's servers , including its production database . The attacker asked for Attack.Ransom $ 400 to unlock the company 's systems , but the victim refused and instead recovered its data via older backups . Attack traced back to Linz teenager The company filed a criminal complaint with the Austrian Federal Criminal Police Office ( Bundeskriminalamt , or BK ) , claiming damages of €3,000 due to production losses . An investigation by Austrian police 's SOKO Clavis unit tracked down the attack to a Linz teenager . Authorities searched the suspect 's homes , one in Linz , and one near Vienna , where he moved . Police arrested the young man , who was later released and is now under an official investigation . According to a BK spokesperson , the teenager denied all accusations . Teenager bought ransomware off the Dark Web Investigators believe the suspect bought the Philadelphia ransomware off the Dark Web . The ransomware is currently on sale on the AlphaBay Dark Web marketplace starting with $ 389 . The ransomware appeared in September 2016 and was based on the Stampado ransomware . Emsisoft released a free decrypter for Philadelphia a day after the ransomware first appeared . According to a Forcepoint report published today , Philadelphia is also the tool of choice for ransomware attacks Attack.Ransom against the healthcare sector . Austrian police are also investigating ( cached mirror ) another ransomware attack Attack.Ransom that targeted an Austrian hotel . In late January , a ransomware attack Attack.Ransom at an Austrian hotel affected the electronic door locking system at an Austrian hotel . At the time of publishing Bleeping Computer could not confirm with Austrian police that this was the same attack they started investigating in mid-March .

Robert Gren was working from home on Friday when , all of a sudden , his laptop stopped working . What he initially thought was just a kink in his computer ’ s software was in fact part of a global ransomware attack Attack.Ransom that has affected more than 200,000 computers and caused untold havoc from China to Britain . Now , Mr. Gren and the thousands of other victims worldwide face an agonizing choice : either hand over the ransom Attack.Ransom — a figure that has climbed to $ 600 for each affected machine — by a deadline this Friday , or potentially lose their digital information , including personal photos , hospital patient records and other priceless data , forever . “ I ’ m pretty devastated , ” said Mr. Gren , 32 , a manager of an online entertainment business in Krakow , Poland , who has spent almost all of his waking hours since Friday looking for ways to reclaim his digital data . “ I ’ ve lost private files that I have no other way of recovering . For me , the damage has been huge. ” That decision has become even more difficult as cybersecurity experts and law enforcement officials have repeatedly warned people against paying the ransom Attack.Ransom ahead of this week ’ s deadline . Aside from dissuading victims from handing over money Attack.Ransom that may help fund further such attacks , they caution that it is not guaranteed the attackers will return control of people ’ s computers even if they pay Attack.Ransom the assailants in bitcoin , a digital currency favored in such ransomware attacks Attack.Ransom that can be difficult to trace . Officials also note that the attackers , who have yet to been named , have provided only three bitcoin addresses — similar to a traditional bank routing number — for all global victims to deposit the ransom Attack.Ransom , so it may prove difficult to know who has paid the digital fees Attack.Ransom . This haphazard planning has led many victims to hold off paying Attack.Ransom , at least until they can guarantee they will get their data back . So far , roughly $ 80,000 has been deposited Attack.Ransom into the bitcoin addresses linked to the attack Attack.Ransom , according to Elliptic , a company that tracks online financial transactions involving virtual currencies . F-Secure , a Finnish cybersecurity firm , has confirmed that some of the 200 individuals that it had identified , who had paid the ransom Attack.Ransom , had successfully had their files decrypted . Yet that represented a small fraction of those affected , and the company said it still remained unlikely that people would regain control of their computers if they paid the online fee Attack.Ransom . The tally of ransom payments Attack.Ransom may rise ahead of Friday ’ s deadline , but cybersecurity experts say the current numbers — both total ransom money paid Attack.Ransom and machines decrypted — are far short of early estimates forecasting that the digital attack may eventually cost victims hundreds of millions of dollars in combined ransom fees Attack.Ransom . “ I predict this may be an epic failure , ” said Kim Peretti , a former senior litigator in the Department of Justice ’ s computer crime and intellectual property division who now is co-chairwoman of the cybersecurity preparedness and response team at Alston & Bird , an international law firm . “ Because of the publicity of this attack and the public ’ s awareness of people potentially not getting their files back , the figures aren ’ t as high as people had first thought. ” For victims of such attacks , the potential loss of personal or business files can be traumatic . In typical ransomware cases , including the most recent hack , assailants send Attack.Phishing an encrypted email to potential targets . The message includes a malware attachment that takes over their machines if opened . The attackers then demand payment Attack.Ransom before returning control of the computers , often through money paid into bitcoin or other largely untraceable online currencies .

And that approach probably works out just fine from a law enforcement organization ’ s perspective . However , from the viewpoint of a private citizen whose entire database has been held hostage by vicious hackers , not paying a ransom Attack.Ransom is hardly an option . According to the FBI ’ s own statistics , ransomware attacks Attack.Ransom are spreading like virus in the US alone , with a spike as alarming as $ 209 million in damages in the first three months of 2016 . When you look at it , the reasons behind the spread of ransomware are quite easy to understand . The malicious coding can be acquired by anyone with an internet connection for as little as a hundred dollars on the Deep Web , the psychological pressure over losing one ’ s important data almost always ends up in a successful heist and the current law enforcement system can and does very little to prevent the situation from going out of control . That , however , is not to say that the law enforcement isn ’ t concerned . In a news report released in April 2016 , the FBI expressed its direct concerns over the unchallenged growth of ransomware attacks Attack.Ransom and urged any victims to not give in to the demand for ransom Attack.Ransom unless all other options are exhausted . Unfortunately , however , as is the case with most ransomware attacks Attack.Ransom , the stakes of losing years worth of important data is always quite high and the ransom demanded Attack.Ransom usually very small , leading most victims to give in to the attackers ’ demands Attack.Ransom before even reaching out to law enforcement . For starters , though , let ’ s try and have a look at what ransomware is , and what differentiates it from other types of malicious coding . The most common form of ransomware is one that infiltrates your network , gains access Attack.Databreach to your data and encrypts them using advanced algorithms to prevent you from accessing your own files . A demand Attack.Ransom for an aggressive amount of money , generally in Bitcoin , is then demanded Attack.Ransom by the perpetrator in exchange for the key that decrypts said data that has been hijacked . There are , of course , several other types of ransomware , such as the kind that block access to the entire operating system or the kind that attaches itself to a partition of the computer ’ s hard drive . Most ransomware come with some sort of encryption key that is used to unlock the stolen data files once ransom is paid Attack.Ransom , though there is absolutely no guarantee that the perpetrator will keep their end of the bargain once money is transferred . The majority of ransomware attacks Attack.Ransom come with a set of identifying characteristics , such as the use of malicious coding that can spread throughout the network , the blocking of access to important data in the victim ’ s servers in a variety of creative ways , including the scrambling of file names and adding different extensions to prevent them from being accessed . Ransomware attacks Attack.Ransom also feature a time limit to add an element of psychological pressure against the victim , after which the data in concern is either stolen Attack.Databreach or deleted from the victim ’ s servers permanently . Attackers these days almost always ask for payment Attack.Ransom in Bitcoin , as the cryptocurrency is incredibly difficult to track as far as payments go . The concern over ransomware lies not in individual cases but the number of cases reported each year , which makes it the most popular cyber-infiltration scenario in current times . According to the Cyber Threat Alliance ( CTA ) , the damages caused by CryptoWall 3 , a particular type of ransomware , hit Attack.Ransom $ 325 million in 2015 alone . As per statistics produced by the Federal Bureau of Investigation , in the first few months of 2016 , a single variant of ransomware infected as many as 100,000 computers each day . In the March of 2016 , the number of computers infected by ransomware technology hit the absolute upper ceiling for the year , reports Symantec . While the cases , when considered individually , may not amount to much , the number of incidents reported worldwide in any given year is clearly a matter of global concern .

In wake of last week ’ s ransomware attack Attack.Ransom , technology specialists warn that ‘ paying money Attack.Ransom to a criminal is never a good idea ’ Cybersecurity experts have warned businesses against meeting hackers ’ demands for money Attack.Ransom in the wake of the “unprecedented” attack Attack.Ransom on hundreds of thousands of computer systems around the world . Ransomware is a type of malicious software that blocks access to a computer or its data and demands money Attack.Ransom to release it . The worm used in Friday ’ s attack Attack.Ransom , dubbed WannaCry or WanaCrypt0r , encrypted more than 200,000 computers in more than 150 countries for ransoms Attack.Ransom of $ 300 to $ 600 to restore access . The full damage of the attack and its economic cost was still unclear , but Europol ’ s director , Rob Wainwright , said its global reach was precedented , and more victims were likely to become known in the coming days . The extent of the WannaCry attack Attack.Ransom prompted questions about what to do in the event of a ransomware infection , with many experts advising against paying the ransom Attack.Ransom , saying not only could it fail to release the data , it could expose victims to further risk . Peter Coroneos , the former chief executive of the Internet Industry Association and an expert on cyber policy , said whether or not to agree to ransomware demands Attack.Ransom presented practical and ethical dilemmas . “ These people are criminals , and paying money to a criminal is never a good idea . However , if it ’ s a trade-off between losing your lifetime ’ s family photos and making a payment Attack.Ransom to a criminal , then it ’ s up to the individual to make that judgment call . “ It would be very hard to walk away. ” But Gregory said it would be “ self-defeating ” for hackers not to release data upon receipt of a ransom Attack.Ransom , “ because that would immediately hit the media , and no one would pay ” . But not all ransomware attacks Attack.Ransom were motivated by financial gains , he added . “ If they ’ re a professional criminal organisation , their business model will be to release people ’ s computers once they ’ ve paid the money Attack.Ransom , but you don ’ t know . It could be someone having a laugh , or someone who ’ s trying to learn , or someone who ’ s released it accidentally . “ You just do not know – that ’ s the problem. ” With such attacks hitting computer systems at an “ ever-increasing rate ” , Gregory said prevention was the best course of action . With outdated operating systems “ easy targets ” , he urged individuals and businesses to automate updates and invest in software that protected against viruses , malware and ransomware across not only their computers , but tablets and mobile phones as well . “ It ’ s a combination of factors that will keep people safe ... For individuals , families have got to work together and companies have to take the time to ensure that their cybersecurity practices are up to date. ” Gregory recommended regular if not daily backups of personal data , which would allow victims to wipe the infected computer , reload their data , and start again .

Infamous Necurs botnet seen sending Attack.Phishing spam emails containing new ransomware to millions of potential victims in just a few hours . A new form of ransomware is indiscriminately targeting millions of PCs , spread by the prolific botnet behind one of the most successful forms of ransomware in the world . The new ransomware is called Jaff and given that it appears to be heavily mimicking tactics of the infamous Locky - the most successful ransomware family of 2016 - it has the potential to become a major nuisance . It 's also brazen in its ransom demands Attack.Ransom , demanding Attack.Ransom victims pay Attack.Ransom 1.79 Bitcoins - currently $ 3,300 - in order to regain access to the infected network and encrypted files . It 's an ambitious ransom Attack.Ransom - most forms of ransomware want a payment Attack.Ransom of between $ 500 and $ 1000 - but the authors are likely to be aware that many organisations are willing to give in and pay Attack.Ransom to avoid losing business-critical files . As noted by cybersecurity researchers at Forcepoint , the Jaff campaign Attack.Ransom sprung to life on May 11 , using the Necurs botnet to send Attack.Phishing millions of spam emails emails Attack.Phishing to targets across the globe in the space of just a few hours . The malicious email itself is sent Attack.Phishing with a subject line referring to a receipt or to a fake document , with the pattern involving the words PDF , Scan , File , Copy or Document followed by an underscore and a string of at least four numbers - four example , one subject line seen by researchers was 'Copy _293636 ' Attached to this email is a PDF document containing an embedded DOCM file and a malicious Macro script . If this is run , the ransomware payload is executed and Jaff targets and encrypts a wide variety of file extensions , renaming them all to end in .jaff . While the attack might seem basic - especially compared with targeted spear-phising attacks Attack.Phishing - the sheer number of messages sent out Attack.Phishing means that even just a tiny percentage of targets open the email , download the attachment and enable the macros , this new ransomware could have a sizeable impact . As with other ransomware attacks Attack.Ransom , the infected victim sees their desktop changed to a ransom note and they 're directed to instructions , telling them their files are encrypted and that they must visit a dark web address in order to pay Attack.Ransom to get their files back . It 's this combined with how the ransomware is spread by Necurs - which leads researchers to suggest that there 's a connection between Jaff and Locky : the Jaff decryptor website and the Locky decryptor website look almost identical . Researchers also note that while the code behind Jaff is less sophisticated than Locky , it carries one major similarity - the ransomware will delete itself from the infected machine if the local language is Russian . If the ransomware does not want to target Russian users this might suggest it originate from Russia and the developers do n't want to cause trouble in their own neighbourhood . While researchers ca n't say for certain if Jaff is definitively linked to the gang behind Locky but those behind it have the funding and skills required to carry out a sophisticated campaign . `` What is clear , given the volume of messages sent , is that the actors behind the campaign have expended significant resources on making such a grand entrance , '' said Forcepoint researchers .

Ransomware is costing Attack.Ransom UK companies a whopping £346 million every year , despite Britain being labelled ‘ the most resolute ’ country for dealing with the cyber attacks Attack.Ransom . In fact , more than 40 per cent of mid-large UK business suffered on average five ransomware attacks Attack.Ransom during the last year , according to research by Vanson Bourne . However , 92 per cent of security professionals feel confident in their ability to combat ransomware in the future . And there was more good news for British . The survey found the UK to be the most resolute , both in refusing to pay ransom demands Attack.Ransom , as well as the most effective in combatting them . They experience the fewest number of attacks : 40 per cent , versus 70 per cent in Germany , 59 per cent in France and 55 per cent in the USA and enjoy a 43 per cent success rate in successfully defending against attacks . The research , commissioned by SentinelOne , reveals that ransomware is costing Attack.Ransom individual businesses around the globe an average of £591,238 per annum . The research all concluded that the number of companies ravaged by ransomware is on the rise . Results show that the overall percentage of companies experiencing ransomware has increased from 48 per cent in 2016 to 56 per cent in 2018 , however the average number per year has fallen from six to five attacks . The amount of time spent decrypting ransomware attacks Attack.Ransom has also increased from 33 to 40 man-hours . The study also reveals that employees are considered the major culprits responsible for introducing the malware into the business . This was further supported by the fact that phishing Attack.Phishing , which seeks to socially engineer employees , was the top attack vector by which ransomware infiltrated the business in 69 per cent of instances . Migo Kedem , director of Product Management at SentinelOne said : “ It ’ s staggering to see the cost to British businesses of £346 million . This figure shows that businesses are becoming increasingly aware that it ’ s not just the ransom demand Attack.Ransom , but rather the ancillary costs of downtime , staff time , lost business , as well as the data recovery costs and reputational damage that are the biggest concern to British businesses. ” He added : “ On a more positive note , it ’ s good to see CISOs feeling more bullish about their ability to tackle ransomware using the latest behavioural AI-based end-point technology . It ’ s also encouraging to see a clear movement against companies caving in to ransomware demands Attack.Ransom , preferring instead to take more proactive measure such as back-ups and patching Vulnerability-related.PatchVulnerability of vulnerable systems . However , the volume of ransomware attacks Attack.Ransom is still increasing and their speed , scale , sophistication and success in evading detection with the growth in file-less and memory-based malware , explains why ransomware will continue to be a major threat to CISOs in 2018 and beyond . ”

The murky ecosystem of ransomware payments Attack.Ransom comes into focus in new research led by Damon McCoy , an assistant professor of computer science and engineering at the NYU Tandon School of Engineering . Ransomware attacks Attack.Ransom , which encrypt and hold a computer user 's files hostage in exchange for payment Attack.Ransom , extort Attack.Ransom millions of dollars from individuals each month , and comprise one of the fastest-growing forms of cyber attack . In a paper slated for presentation at the IEEE Symposium on Security and Privacy in May , McCoy and a team including researchers from the University of California , San Diego ; Princeton University ; Google ; and the blockchain analytics firm Chainalysis provide the first detailed account of the ransomware payment ecosystem , from initial attack to cash-out . Key findings include the discovery that South Koreans are disproportionately impacted Attack.Ransom by ransomware campaigns , with analysis revealing that $ 2.5 million of the $ 16 million in ransomware payments Attack.Ransom tracked by the researchers was paid Attack.Ransom in South Korea . The paper 's authors call for additional research to determine the reason that so many South Koreans are victimized and how they can be protected . The team also found that most ransomware operators used a Russian bitcoin exchange , BTC-E , to convert bitcoin to fiat currencies . ( BTC-E has since been seized by the FBI . ) The researchers estimate that at least 20,000 individuals made ransomware payments Attack.Ransom over the past two years , at a confirmed cost of $ 16 million , although the actual payment total is likely far higher . McCoy and his collaborators took advantage of the public nature of the bitcoin blockchain technology to trace ransom payments Attack.Ransom over a two-year period¬ . Bitcoins are the most common currency of ransomware payments Attack.Ransom , and because most victims do not own them , the initial bitcoin purchase provides a starting point for tracking payments . Each ransomware victim is often given a unique payment address that directs to a bitcoin wallet where the ransom Attack.Ransom is collected . The research team tapped public reports of ransomware attacks Attack.Ransom to identify these addresses and correlate them with blockchain transactions . To boost the number of transactions available for analysis , the team also executed real ransomware binaries in a controlled experimental environment , essentially becoming victims themselves and making micropayments to real ransom wallets in order to follow the bitcoin trail . `` Ransomware operators ultimately direct bitcoin to a central account that they cash out periodically , and by injecting a little bit of our own money into the larger flow we could identify those central accounts , see the other payments flowing in , and begin to understand the number of victims and the amount of money being collected , '' McCoy said . The research team acknowledged that ethical issues prevent exploration of certain aspects of the ransomware ecosystem , including determining the percentage of victims who actually pay Attack.Ransom to recover their files . McCoy explained that despite having the ability to check for activity connected to a specific payment address , doing so would effectively `` start the clock '' and potentially cause victims to either pay a double ransom Attack.Ransom or lose the opportunity to recover their files altogether . Criminal use of cryptocurrencies is one of McCoy 's research focuses . He and fellow researchers previously tracked human traffickers through their use of Bitcoin advertising .

Although Robert Herjavec , an investor on ABC 's `` Shark Tank , '' expects the price of bitcoin to `` skyrocket , '' he has no plans to personally buy any . That 's because as the CEO of cybersecurity firm Herjavec Group , he does n't want to support the growing trend of hackers using cryptocurrency . `` I ca n't invest in something that my enemy uses as funds , '' he explained on CNBC 's `` Squawk Alley . '' Indeed , `` If there was no cryptocurrency , much of the large hacks that we 're seeing today would n't exist , '' Herjavec told Money . As one example , Herjavec is concerned with the role cryptocurrency plays in ransomware attacks Attack.Ransom . `` Cryptocurrency permits anonymity , '' he explains to CNBC Make It . `` It 's a very popular form of payment for ransomware in particular . '' Ransomware is a type of software that locks or encrypts a computer user 's data and files , in affect holding it hostage . To release the information , a hacker will demand a ransom payment Attack.Ransom . Ransomware attacks Attack.Ransom increased 6,000 percent in 2016 from 2015 , according to a study from IBM Security . And in 2017 , 200,000 computers in 150 countries belonging to businesses , governments and even the U.K. National Health Service were impacted Attack.Ransom by the ransomware virus known as WannaCry . In that case , victims were told to make a payment Attack.Ransom in bitcoin to get their computers back . Hackers often demand the ransom Attack.Ransom be paid in cryptocurrency because it allows them to remain anonymous , Herjavec says . `` I can take over your computer or personal information , hold it for ransom Attack.Ransom , give you instructions on how to create a virtual wallet , force Attack.Ransom you to pay Attack.Ransom me , and you have no way of finding out who I am , '' Herjavec explains . That 's because a bitcoin wallet is only identified by a number , and `` payments are direct without a bank or credit card company acting as the middle man , '' Herjavec says . `` There is no money trail , so it 's very difficult to track back to an individual . '' With WannaCry , the hackers asked for Attack.Ransom $ 300 worth of bitcoin from victims , and if they waited over 72 hours to pay Attack.Ransom , the fine increased to $ 600 . If they waited a week , their information would be locked for good . The Trump administration pointed to North Korea as the originator of the attack . In 2016 , ransomware was used to coerce Hollywood Presbyterian Medical Center , a hospital in Los Angeles , to pay Attack.Ransom 40 bitcoin to hackers , The New York Times reports . That sum was then worth $ 17,000 . Bitcoin closed at $ 10,779.90 on Tuesday , March 6 , according to CoinMarketCap , which makes those 40 coins worth about $ 431,196 . To protect yourself from ransomware attacks Attack.Ransom , take steps to secure your online information . `` Keep your computer and data safe by backing up often , using cloud services with dual factor authentication and complex passwords , '' Herjavec suggests . `` Have anti-virus [ software ] installed and kept up to date .
