After WannaCry, UIWIX Ransomware and Monero-Mining Malware Follow Suit

Last Updated: 2017-05-17 16:33:21

WannaCry ransomware’s outbreak during the weekend was mitigated by having its kill switch domain registered. It was only a matter of time, however, for other cybercriminals to follow suit. Case in point: the emergence of UIWIX ransomware (detected as RANSOM_UIWIX.A) and one notable Trojan our sensors detected.

Since the release of the ETERNALBLUE exploit by ‘The Shadow Brokers’ last we’ve have been watching for a mass attack on global networks. This came on Friday 12th May when it was bundled with ransomware called WanaCrypt0r and let loose. Initial reports of attacks were highlighted by Telefonica in Spain but the malware quickly spread to networks in the UK where the National Health Service (NHS) was impacted, followed by many other networks across the world.

On Friday, May 12, attackers spread a massive ransomware attack worldwide using the EternalBlue exploit to rapidly propagate the malware over corporate LANs and wireless networks. EternalBlue, originally exposed on April 14 as part of the Shadow Brokers dump of NSA hacking tools, leverages a vulnerability (MS17-010) in Microsoft Server Message Block (SMB) on TCP port 445 to discover vulnerable computers on a network and laterally spread malicious payloads of the attacker’s choice. This particular attack also appeared to use an NSA backdoor called DoublePulsar to actually install the ransomware known as WannaCry.
