WannaCry Ransomware Pandemic
WannaCry ransomware hit hard late last week, and enterprises worldwide are bracing for further waves of infestation. The hitherto obscure strain of ransomware propagated in wormlike fashion against systems running older Microsoft software. It exploited the vulnerability the Shadow Brokers leaked last month as the weaponized EternalBlue tool. Affected systems are running old and in some cases pirated versions of Microsoft operating systems, specifically Windows XP, Windows 8, and Server 2003. The rate of infection has been very high, temporarily slowed by discovery and activation of a "kill switch," but most observers expect renewed attack as the unknown controllers upgrade the malware. We have a quick overview and some industry reactions here.
