Summary
LockBit Ransomware (a.k.a. ABCD) is yet another ransomware group operating in the RaaS (Ransomware-as-a-Service) model, following the same architecture as other major threat groups, like REvil. This threat emerged in September 2019 and is still being improved by its creators. In June 2021, the LockBit group announced the release of LockBit 2.0, which included a new website hosted on the deep web, as well as a new feature to encrypt Windows domains using group policy.
On August 11, 2021, the LockBit ransomware group announced in their deep web forum that they have infected the global IT consultancy company Accenture.
According to the company Cyble, the attackers have allegedly stolen about 6TB of data, and are demanding $50M (USD) as ransom. Also, Cyble mentioned that this attack was supposedly carried out by an insider, however, that has not been verified yet. The IT giant Accenture has confirmed the attack and also affirmed that the breach had no impact on their operations or systems.
The period established for Accenture to pay the ransom was August 11, 2021, which has now passed.
However, as I am writing this blog post, the period to pay the ransom was changed to August 12, 2021, at the end of the day.
At this point, it’s unclear how the attack was carried out, or if LockBit really stole sensitive data from the company. In this threat coverage report, we will briefly show how LockBit works, describing some features used for anti-analysis.
Threat
LockBit ransomware is developed in both C and Assembly and uses AES + ECC to encrypt the files. The group operates in the RaaS model, and on their official website hosted on the deep web, we can find an advertisement trying to attract more affiliates into the scheme.
