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 .

Cybersecurity experts and companies on Long Island are looking for ways to shore up the weakest link on company computer networks : the employee . Local cybersecurity professionals are creating interactive comic books , testing employees with simulated phishing emails — tailored messages that seek to obtain key information , such as passwords — and seeking to convince top executives that the threat of business disruption from hacking requires their attention . “ The biggest problem is not the technology ; it ’ s the people , ” said Laurin Buchanan , principal investigator at Secure Decisions , a division of Northport software developer Applied Visions Inc. Sixty percent of cyber-assaults on businesses can be traced to insiders ’ actions , either inadvertent or malicious , according to a 2016 study by IBM Security . The average cost of a data breach Attack.Databreach for U.S. companies is $ 7.4 million , or $ 225 per lost or stolen record , a June 2017 study by IBM and the Ponemon Institute , a Traverse City , Michigan , researcher , found . Costs related to data breaches Attack.Databreach can include the investigation , legal costs to defend against and settle class-action lawsuits , credit monitoring for affected customers , and coverage of fraud losses . Harder to gauge is the cost to a company ’ s reputation . One of the largest hacks Attack.Databreach ever was disclosed this month , when credit reporting company Equifax Inc. revealed that sensitive data from 143 million consumers , including Social Security numbers and birth dates , was exposed Attack.Databreach . A stock analyst from Stifel Financial Corp. estimated that the attack will cost Equifax about $ 300 million in direct expenses . Investors seem to think the incident will have a much greater impact on At a seminar in Garden City this month , Henry Prince , chief security officer at Shellproof Security in Greenvale , explained how in a ransomware attack Attack.Ransom — one of many types — cybercriminals can buy specialized tools such as those used to send Attack.Phishing phishing emails . The easy availability of that software means that hackers require “ no programming experience , ” Prince said . Phishing emails can be blocked by company email filters , firewalls and anti-virus software . But if one gets through Attack.Phishing and an employee clicks on the link in the phishing email , the business ’ network is compromised . Hackers can then encrypt files , preventing access to them by the company and crippling the business , Prince said at the seminar . Hackers then can demand payment Attack.Ransom , typically in an untraceable cryptocurrency like Bitcoin — a digital asset that uses encryption — before agreeing to decrypt the files . “ Ransomware is a business to these people , ” Prince said . “ Ninety-nine percent of the time , ransomware requires user interaction to infect. ” Della Ragione echoed that sentiment : “ The greatest risk at a company is the employees . Training employees is one of the best steps in shoring up your defenses. ” In response , many local experts and companies focus on teaching employees how to resist hackers ’ tricks . Secure Decisions has developed interactive comics to teach employees ways of detecting “ phishing ” emails and other hacking attempts . The company has gotten more than $ 1 million for research related to the interactive comic project , known as Comic-BEE , from the Department of Homeland Security , as well as a grant for $ 162,262 from the National Science Foundation . The comics , inspired by children ’ s “ Choose Your Own Adventure ” books , feature different plots depending on the reader ’ s choices . “ If you can give people the opportunity to role-play , some of the exhortations by the experts will make more sense , ” Buchanan said . The comics are being field-tested at several companies and Stony Brook University . They were featured in July at a DHS cybersecurity workshop in Washington , D.C. Radu Sion , a computer science professor at Stony Brook and director of its National Security Institute , which studies how to secure digital communications , acknowledged that security is far from a priority for most users . “ Ultimately , the average Joe doesn ’ t care , ” he said . “ You [ should ] treat the vast majority of your users as easily hackable. ” Northwell Health , the New Hyde Park-based health care system that is the largest private employer in New York State , is trying to find and get the attention of those inattentive employees . Kathy Hughes , Northwell vice president and chief information security officer , sends out “ phishing simulations ” to the workforce . The emails are designed to mimic Attack.Phishing a real phishing campaign Attack.Phishing that seeks passwords and personal information . In April , for instance , Northwell sent out Attack.Phishing phishing emails with a tax theme . Hughes collects reports on which employees take the bait Attack.Phishing by user , department and job function . “ We present them with a teachable moment , ” she said . “ We point out things in the email that they should have looked at more carefully. ” The emails are supplemented with newsletters , screen savers and digital signage reminding users that hackers are lurking . Another tool : Non-Northwell emails have an “ external ” notation in the subject line , making it harder for outsiders to pretend to be Attack.Phishing a colleague . “ We let [ the employees ] know that they are part of the security team , ” she said . “ Everybody has a responsibility for security. ” One of the most important constituencies for security is top executives . Drew Walker , a cybersecurity expert at Vector Solutions in Tampa , Florida , said many executives would rather not know about vulnerabilities to their computer systems , because knowledge of a hole makes them legally vulnerable and casts them in a bad light . “ Nine times out of 10 , they don ’ t want to hear it , ” he said . “ It makes them look bad. ” Richard Frankel , a former FBI special agent who is of counsel at Ruskin Moscou , said that company tests of cybersecurity readiness often snare CEOs who weren ’ t paying attention to training . But attorney Della Ragione said high-profile attacks are getting notice from executives . “ Everyone ’ s consciousness is being raised , ” she said . Data leaks Attack.Databreach at Long Island companies have caused executives to heighten security . In 2014 , Farmingdale-based supermarket chain Uncle Giuseppe ’ s Marketplace said that foreign hackers had breached Attack.Databreach the credit card database of three stores . Joseph Neglia , director of information technology at Uncle Giuseppe ’ s , said that after the data breach Attack.Databreach , which affected about 100 customers , the company began scheduling “ monthly vulnerability scans ” and upgraded its monitoring and security systems . For businesses , Stony Brook ’ s Sion said , the cybersecurity threat is real and immediate . “ I need one second with your machine to compromise it forever and ever , ” he said . “ It ’ s an uphill battle . ”
