ExfilSquad Ransomware Group Claims Responsibility for Suspected Wesco International Data Breach
The ransomware group ExfilSquad has claimed responsibility for a suspected cyberattack on Wesco International, a major electrical distributor and servicer, alleging the theft of approximately 2.6 million records containing customer, employee, and other sensitive data. The incident is believed to have occurred on July 26, 2026, with the group reportedly exfiltrating 40 gigabytes of data from the company.
Cybersecurity monitoring platform Ransomware.live and blog DeXpose.io have both cited ExfilSquad as the likely perpetrator, though details about the breach’s scope and nature remain unconfirmed. Legal professionals associated with ClassAction.org are investigating the incident, seeking affected individuals including current and former employees, suppliers, and customers to determine whether a class action lawsuit can be filed. Such a case could seek compensation for privacy violations, financial losses, and other damages.
At this time, Wesco International has not publicly confirmed the breach, and no additional official statements have been released regarding the incident’s impact or response efforts. The situation remains under investigation.
