Disclosure context

About securotrop

Securotrop is a relatively new ransomware group that emerged in July 2025 and operates with apparent financial motivations, having targeted at least 31 victims across multiple sectors. The group primarily targets English-speaking countries including the United States, Canada, and the United Kingdom, with their attacks focused heavily on manufacturing companies, business services firms, construction organizations, and telecommunications providers. Due to the group's recent emergence and limited public documentation from major cybersecurity agencies and researchers, specific details about their country of origin, operational structure, attack methodologies, and technical capabilities remain largely undocumented in open-source intelligence reports. The targeting pattern suggests a focus on critical infrastructure and industrial sectors that may be willing to pay ransoms to quickly restore operations, though no major high-profile attacks or record ransom demands have been publicly reported by established threat intelligence sources. Given the group's recent formation in mid-2025, Securotrop appears to remain active, though comprehensive analysis of their tactics, techniques, and procedures awaits further documentation by cybersecurity researchers and law enforcement agencies. The group has been linked to 35 public disclosures across our corpus. First observed on a leak site on July 22, 2025; most recent post May 4, 2026. The operation is currently active.
