ranstreet is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 1 public victims claimed by this operator between December 21, 2023. 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.
How we know this. Operator profiles on Darkfield are built from continuous monitoring of every leak site the group is known to operate, cross-correlated with community-curated feeds (RansomLook, ransomware.live, RansomWatch, MISP-galaxy). Status flips from active to inactive when no new disclosure appears for 60 days. MITRE ATT&CK mappings shown in the interactive section below are sourced from CISA, vendor analysis, and the MITRE community catalog — we attribute each technique back to its source. Aliases reflect operator re-brands and affiliate splits.
