A ransomware group operating under the name securotrop has posted a claim on its dark web leak site stating that it obtained data from Shelco Filters, with the listing dated September 12, 2026. This claim comes from the group’s own leak-site posting, tracked by ransomware.live, a security research platform that monitors ransomware groups’ public disclosures. It is important to stress that this is an allegation made by a criminal extortion group, not a confirmed security incident. Shelco Filters has not issued any public statement addressing the claim, and no regulator or independent authority has verified it.
