Astrum was known to have been exclusively used by the AdGholas malvertising campaign that delivered a plethora of threats including banking Trojans Dreambot/Gozi (also known as Ursnif, and detected by Trend Micro as BKDR_URSNIF) and RAMNIT (TROJ_RAMNIT, PE_RAMNIT). We’re also seeing Astrum redirected by the Seamless malvertising campaign, which is known for using the Rig exploit kit.

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.

Recent identified malware with compilation and distribution timestamps that has code, infrastructure, and themes overlapping with threats described previously in the Operation Blockbuster report, written by researchers at Novetta. This report details the activities from a group they named Lazarus, their tools, and the techniques they use to infiltrate computer networks. The Lazarus group is tied to the 2014 attack on Sony Pictures Entertainment and the 2013 DarkSeoul attacks.

Cyber espionage actors, now designated by FireEye as APT32 (OceanLotus Group), are carrying out intrusions into private sector companies across multiple industries and have also targeted foreign governments, dissidents, and journalists. FireEye assesses that APT32 leverages a unique suite of fully-featured malware, in conjunction with commercially-available tools, to conduct targeted operations that are aligned with Vietnamese state interests.
