Ranstreet is an obscure ransomware group that emerged in December 2023 with limited observed activity and appears to be financially motivated based on typical ransomware operational patterns. The group's origin and affiliations remain unknown, with no publicly documented information from major threat intelligence sources regarding their country of origin, connections to other cybercriminal organizations, or operational structure. Their attack methodology, tools, and specific techniques have not been detailed in public reporting from established security research organizations, likely due to their minimal observed activity and limited victim base. The group has been linked to only one documented victim, with their targeting focused on Portugal, though the specific organization and impact details have not been disclosed in major threat intelligence reports. Ranstreet's current operational status remains unclear given the lack of substantial public documentation and their limited attack footprint since their recent emergence. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on December 21, 2023. 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.
