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 . ”
