LockBit Ransomware Abuses Windows Defender to Deploy Cobalt Strike Payload

LockBit Ransomware Abuses Windows Defender to Deploy Cobalt Strike Payload
August 02, 2022Ravie Lakshmanan
A threat actor associated with the LockBit 3.0 ransomware-as-a-service (RaaS) operation has been observed abusing the Windows Defender command-line tool to decrypt and load Cobalt Strike payloads.  According to a report published by SentinelOne last week, the incident occurred after obtaining initial access via the  Log4Shell vulnerability  against an unpatched VMware Horizon Server. "Once initial access had been achieved, the threat actors performed a series of enumeration commands and attempted to run multiple post-exploitation tools, including Meterpreter, PowerShell Empire, and a new way to side-load Cobalt Strike," researchers Julio Dantas, James Haughom, and Julien Reisdorffer  said . LockBit 3.0 (aka LockBit Black), which comes with the tagline "Make Ransomware Great Again!," is the  next iteration  of the prolific  LockBit RaaS family  that emerged in June 2022 to iron out  critical weaknesses  discovered in its predecessor. It's notable for insti

LockBit ransomware attacks are constantly evolving by making use of a wide range of techniques to infect targets while also taking steps to disable endpoint security solutions. "The affiliates that use LockBit's services conduct their attacks according to their preference and use different tools and techniques to achieve their goal," Cybereason security analysts Loïc Castel and Gal Romano  said . "As the attack progresses further along the kill chain, the activities from different cases tend to converge to similar activities." LockBit, which operates on a ransomware-as-a-service (RaaS) model like most groups, was first observed in September 2019 and has since emerged as the most dominant ransomware strain this year, surpassing other well-known groups like  Conti ,  Hive , and  BlackCat . This involves the malware authors licensing access to affiliates, who execute the attacks in exchange for using their tools and infrastructure and earn as much as 80% of ea

Evil Corp Cybercrime Group Shifts to LockBit Ransomware to Evade Sanctions

Evil Corp Cybercrime Group Shifts to LockBit Ransomware to Evade Sanctions

The threat cluster dubbed UNC2165, which shares numerous overlaps with a Russia-based cybercrime group known as Evil Corp, has been linked to multiple LockBit ransomware intrusions in what's seen as an attempt by the latter to get around  sanctions  imposed by the U.S. Treasury in December 2019. "These actors have shifted away from using exclusive ransomware variants to LockBit — a well-known ransomware as a service (RaaS) — in their operations, likely to hinder attribution efforts in order to evade sanctions," threat intelligence firm Mandiant  noted  in an analysis last week. Active since 2019, UNC2165 is known to obtain initial access to victim networks via stolen credentials and a JavaScript-based downloader malware called  FakeUpdates  (aka SocGholish), leveraging it to previously deploy  Hades  ransomware. Hades is the work of a financially motivated hacking group named Evil Corp, which is also called by the monikers Gold Drake and Indrik Spider and has been at

Nearly 34 Ransomware Variants Observed in Hundreds of Cyberattacks in Q4 2021

As many as 722 ransomware attacks were observed during the fourth quarter of 2021, with LockBit 2.0, Conti, PYSA, Hive, and Grief emerging as the most prevalent strains, according to new research published by Intel 471. The attacks mark an increase of 110 and 129 attacks from the third and second quarters of 2021, respectively. In all, 34 different ransomware variants were detected during the three-month-period between October and December 2021. "The most prevalent ransomware strain in the fourth quarter of 2021 was LockBit 2.0, which was responsible for 29.7% of all reported incidents, followed by Conti at 19%, PYSA at 10.5%, and Hive at 10.1%," the researchers said in a report shared with The Hacker News. Some of the most impacted sectors during the quarterly period were consumer and industrial products; manufacturing; professional services and consulting; real estate; life sciences and health care; technology, media and telecommunications; energy, resources and agric

IT Giant Accenture Hit by LockBit Ransomware; Hackers Threaten to Leak Data

IT Giant Accenture Hit by LockBit Ransomware; Hackers Threaten to Leak Data

Global IT consultancy giant Accenture has become the latest company to be hit by the LockBit ransomware gang, according to a post made by the operators on their dark web portal, likely filling a void left in the wake of DarkSide and REvil shutdown. "These people are beyond privacy and security. I really hope that their services are better than what I saw as an insider," read a message posted on the data leak website. Accenture  said  it has since restored the affected systems from backups. LockBit, like its now-defunct DarkSide and REvil counterparts, operates using a ransomware-as-a-service (RaaS) model, roping in other cybercriminals (aka affiliates) to carry out the intrusion using its platform, with the payments often divided between the criminal entity directing the attack and the core developers of the malware. The ransomware group emerged on the threat landscape in September 2019, and in June 2021 launched LockBit 2.0 along with an advertising campaign to recruit
