What Happened?
On September 12th, 2026, the Securotrop ransomware group listed Shelco Filters on its dark web leak site, as reported by Ransomware.live. The posting claims 191 GB of data associated with Shelco Filters, with a status listed as “AWAITING.” These figures are attacker-side claims only. No breach date, discovery date, or specific data types have been identified, and it has not been confirmed whether any systems were encrypted or whether data was actually exfiltrated. Shelco Filters has not publicly confirmed any cybersecurity incident, and no independent corroborating sources — such as regulatory filings, consumer notification letters, or news reporting specific to this incident — were found.
Securotrop is a relatively young ransomware group, established in early 2025, that operates as an affiliate within the Qilin ransomware-as-a-service network while maintaining an independent identity. Security researchers at FalconFeeds.io have noted the Qilin affiliation, and WatchGuard classifies Securotrop as active crypto-ransomware capable of both direct extortion and double extortion tactics. The group focuses exclusively on commercial targets and has approximately 32 documented claimed victims. No prior cybersecurity incidents involving Shelco Filters were found.
