Attorneys at Almeida Law Group are investigating whether a class action lawsuit can be filed on behalf of individuals affected by a possible Prefix Corp data breach. According to dark web monitoring sources, a hacker group calling itself securotrop claimed responsibility for a cyberattack on Prefix Corp in a post first observed in September 2026, alleging it had gained access to internal company systems. As of this writing, Prefix Corp has not issued a public confirmation of the incident, and the exact scope of any exposed data remains unknown. If you believe you were affected, contact Almeida Law Group.
About Prefix Corp
Prefix Corporation is a Michigan-based prototype development, concept vehicle engineering, and advanced manufacturing company founded in 1979. Headquartered in Rochester Hills, Michigan, the company serves automotive, aviation, entertainment, and defense sectors, counting Mercedes-Benz, General Motors, and Disney among its clients. It is family-owned by the Zeile family, operates multiple facilities across Southeast Michigan, and employs more than 200 people.
What Happened?
Prefix Corp was listed on the dark web leak site of the ransomware group Securotrop, according to a ransomware leak-site allegation reported by Ransomware.live and independently noted by RedPacket Security. The listing, first observed on September 18th, 2026, claims approximately 1,135 GB of data and shows a status of “Awaiting.” The listing does not specify a compromise date, whether systems were encrypted, what data categories may be involved, or any ransom demand. No independent corroborating source was found to confirm the attacker’s claims, and Prefix Corporation has not publicly confirmed the incident. No regulatory filings, breach notification letters, or victim-side disclosures have been identified.
Securotrop is a relatively young ransomware group established in early 2025. According to FalconFeeds.io, Securotrop appears to operate as an affiliate within the Qilin ransomware network while maintaining an independent identity. WatchGuard classifies it as active crypto-ransomware employing double extortion tactics, and SuspectFile reports that the group focuses exclusively on commercial targets, avoiding healthcare and government entities. This remains an unverified attacker-side allegation only.
