Varonis summarizes Mimikatz as an open-source application that allows users to view and save authentication credentials like Kerberos tickets. Benjamin Delpy continues to lead Mimikatz developments, so the toolset works with the current release of Windows and includes the most up-to-date attacks. Attackers commonly use Mimikatz to steal credentials and escalate privileges: in most cases, endpoint protection software and anti-virus systems will detect and delete it. Conversely, pentesters use Mimikatz to detect and exploit vulnerabilities in your networks so you can fix them.

As described on the Github repository page, "A sugared version of RottenPotatoNG, with a bit of juice, i.e. another Local Privilege Escalation tool, from a Windows Service Accounts to NT AUTHORITY\SYSTEM".

Kongtuke is a sophisticated TDS system that was initially discovered around May 2024. Making use of compromised CMS Websites, Kongtuke redirects website visitors through a multi-stage infection process ultimately leading to device infection. Initially using fake Update lures, it started to use FakeCaptcha lures at the beginning of 2025. It is likely an initial access service, selling infections to both Ransomware affiliates and other IA vendors like SocGholish.

Qilin ransomware, initially observed in July 2022 under the name “Agenda,” operates on a Ransomware-as-a-Service (RaaS) model. This model allows core developers to provide their malicious software and infrastructure to affiliates in exchange for a percentage of the profits generated from attacks. The name “Qilin” references a Chinese mythological creature symbolizing power and prosperity, a fitting metaphor for the group’s perceived influence and financial objectives. Despite the Chinese name, the group is linked to Russian-speaking cybercriminals, often recruiting affiliates on Russian-language forums and notably excluding Commonwealth of Independent States (CIS) countries from its targets.

According to Proofpoint, this is a fork of Stealerium that has high overlap with its originating codebase.
