All of the top three malware families that impacted networks globally in May were previously unseen attacks, says Check Point
SAN CARLOS, Calif., June 20, 2017 (GLOBE NEWSWIRE) — Check Point® Software Technologies Ltd. (NASDAQ:CHKP) has revealed that more than one in four organizations globally was affected by the Fireball or WannaCry attacks during May, in the company’s latest Global Threat Impact Index.
Two of top three malware families that impacted networks globally were zero-day, previously unseen attacks. Fireball impacted one in five organizations worldwide, with second-placed RoughTed impacting 16% and third-placed WannaCry affecting nearly 8% of organizations globally. These two malware variants, Fireball and WannaCry, rapidly spread worldwide throughout the month of May.
The most prevalent malware highlight the wide range of attack vectors and targets cyber-criminals are utilizing, impacting all stages of the infection chain. Fireball takes over target browsers and turns them into zombies, which it can then use for a wide range of actions including dropping additional malware, or stealing valuable credentials. By contrast, RoughTed is a large-scale malvertising campaign, and WannaCry takes advantage of a Windows SMB exploit called EternalBlue in order to propagate within and between networks. WannaCry was particularly high profile, bringing down a myriad of networks worldwide.
In addition to the top three, there were also other new variants seen within the top ten of the index including Jaff (8th) another form of ransomware, demonstrating how profitable this particular attack vector is proving for malicious parties.
