Evolution of ransomware makes it hard to defend against, warns National Crime Agency

Ransomware is increasingly effective because of changes in the way it operates. Because cyber-extortion is a numbers game – the more devices you infect the more you earn – the objective of the attackers is to infect as many devices as quickly as possible, said Paul Edmunds, head of technology at the National Crime Agency (NCA). Therefore they need to get around defences such as restricted admin rights.

Describing ransomware as a “growing and present threat”, he told the audience at last week’s Computing Security and Risk Management Summit that whereas early examples tended to be delivered as email attachments which had to be downloaded and executed by the victim, subsequent strains such as WannaCry and NotPetya were much more proactive in seeking out and infecting vulnerable machines.

“We’re starting to see other attack vectors that are growing in importance, scanning and finding unpatched vulnerabilities on a machine,” Edmunds said.

Protect, defend, respond: Cyber Security and Forensics students on how to combat cyber threats

Why would some­one tar­get me?” Austin Kleineschay, pres­i­dent of the Cyber Secu­rity and Foren­sic Stu­dent Orga­ni­za­tion (CSFSO), said that’s a com­mon ques­tion about cyber­at­tacks. The mes­sage of CSFSO’s annual inter­net secu­rity work­shop: we are all poten­tial tar­gets for hack­ers and cyber criminals.

The “Think Safe, Be Safe,” work­shop focused on secu­rity prob­lems and pos­si­ble solu­tions. It was held Sat­ur­day, Oct. 28, at the Jason R. Carter Sci­ence Edu­ca­tion Cen­ter. Com­mu­nity mem­bers, stu­dents and fac­ulty attended.

Kleineschay opened the event with a dis­cus­sion of cur­rent inter­net secu­rity threats. He chal­lenged every­one to imag­ine what could hap­pen if a cyber crim­i­nal accessed their pho­tos, emails, pass­words, bank accounts and credit card num­bers. Offend­ers might not even be human, as “bots” can find a computer’s secu­rity weak­nesses, Kleineschay said.

Secu­rity bugs will always exist, humans are fal­li­ble,” said Kleineschay. The threat of viruses, worms, Tro­jans, ran­somware and mal­ware
