Cerber is a ransomware-as-a-service (RaaS) operation that emerged around 2016-2017, primarily motivated by financial gain through widespread ransomware distribution. The group is believed to operate from Russian-speaking territories, functioning as a RaaS model where affiliates pay for access to the ransomware and infrastructure while the core operators take a percentage of ransom payments. Cerber primarily gained initial access through malicious email attachments, exploit kits, and compromised websites, utilizing strong encryption methods and employing voice messages to communicate ransom demands to victims rather than traditional text notes. The ransomware was notable for its sophisticated evasion techniques and ability to encrypt files with strong cryptographic algorithms. While Cerber was once considered one of the most prevalent ransomware families, with security researchers documenting numerous variants and widespread distribution campaigns between 2016-2017, the operation appears to have significantly declined in activity by 2018, with most security firms reporting minimal new Cerber samples in recent years, though some variants may still circulate in limited campaigns. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on January 9, 2017. The operation is currently inactive.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
