Key Takeaways

• Ransomware claim: The Cl0p ransomware group has added Logitech, a Swiss-based technology company, to its list of alleged victims.
• Likely exploit: The attack is believed to be part of a broader campaign exploiting a zero-day vulnerability in Oracle E-Business Suite.
• ICT sector targeted: The incident is one of nine new claims made today, targeting companies primarily in the ICT and manufacturing sectors.

The Cl0p ransomware group has claimed responsibility for a significant cyberattack against Swiss technology and computer peripherals manufacturer Logitech. On November 6, 2025, the notorious cybercriminal collective listed Logitech on its dark web portal as one of its latest victims. 

This incident is part of a larger wave of purported attacks, with Cl0p hackers adding a total of nine new organizations from various countries to its list on the same day.

Possible Logitech Breach Attack Vector

Security analysts believe the Cl0p ransomware Logitech breach may be linked to a widespread campaign exploiting a zero-day vulnerability in Oracle E-Business Suite (EBS) that affected over 100 organizations. 

This critical flaw allows threat actors to compromise enterprise systems, exfiltrate sensitive data, and deploy ransomware. The pattern of attacks suggests Cl0p may be systematically targeting organizations that have not yet patched the Oracle vulnerability, even though the fix is available. 

The other major international companies listed alongside Logitech, Cl0p are:

• Rheem Manufacturing U.S.
• International Motors, LLC U.S.
• MKS Inc. U.S.
• Trimble Inc. U.S.
• Kirby Corporation U.S.
• ELSEWEDY ELECTRIC Egypt
• John Wood Group PLC Great Britain
• Kier Group Great Britain

The group's focus on high-value corporate targets across Europe and North America demonstrates its technical proficiency and organized approach.

Broad Implications for the Global ICT Sector

The claim against Logitech highlights the persistent and escalating threats facing the global Information and Communications Technology (ICT) sector. The status of the Russian threat actor’s claims against all nine victims is currently pending verification. 

For organizations in the ICT sector, this event underscores the critical importance of rapid vulnerability management and proactive threat intelligence to defend against sophisticated adversaries exploiting enterprise software vulnerabilities. 

Last month, Harvard confirmed suffering a Cl0p data breach tied to an Oracle EBS flaw.
