The global tech giant, Logitech, has confirmed a recent cybersecurity incident regarding a zero-day flaw on its systems by a threat actor.
-
Logitech’s disclosure follows an announcement by the notorious CL0P ransomware group, claiming to have exfiltrated the firm’s data.
-
Following the discovery of the hack, the firm commenced an investigation and a complementary response plan.
Worldwide electronics hardware firm Logitech has announced a cybersecurity situation regarding unlicensed access and data theft from its internal networks. The company made this disclosure on Friday, November 14, 2025, stating that an anonymous actor exploited a zero-day flaw in one of the third-party software programs that it used.
Logitech Discloses Cybersecurity Breach on its Internal IT Systems
As per a filing with the United States Securities and Exchange Commission (SEC), Logitech noted that a third-party software program that it used had an unknown zero-day vulnerability. This flaw enabled the threat actor to duplicate specific files from Logitech’s internal IT systems before the firm could fix the vulnerability after it deployed an update.
This disclosure followed a claim by the notorious CL0P ransomware gang that they had stolen the firm’s data. This group is known for sophisticated attacks exploiting third-party software, as seen in their recent breach of security giant Entrust via an Oracle zero-day.
According to the group’s November 5th posting on its website on the dark web, the hacker group did not issue any further threats or ransom demands against the firm.
Logitech is actively investigating a suspected data breach and believes attackers may have accessed limited consumer, employee, supplier, and customer relationship data.
Based on records, it can be confirmed that there was no Sensitive Personal Information contained on the system that the hacker accessed. Furthermore, according to information recently communicated about this cyberattack, the hackers also appear not to have obtained access to Highly Sensitive Personally Identifiable Information (HS-PII) or Protected Health Information (PHI). Thus, the hack only covered internal data and did not include the firm’s consumer-facing services or products.
This incident is part of a worrying trend where major corporations are being compromised through third-party software vulnerabilities. It’s a pattern we’ve seen recently in other significant breaches, such as the Dutch firm Eurofiber’s data leak that exposed French customer data on the darknet. In both cases, a trusted software component became the weakest link.
Logitech Responds to Breach Incident
After detecting the breach, the electronics giant launched an investigation and a complementary plan. Logitech is working with well-known companies in the field of cybersecurity to survey and establish control over the event. As soon as Logitech discovered the hack, it immediately patched the zero-day vulnerability used to carry out the attack by the malicious entity.
This patch update salvaged the weakness and reduced further risk of unlicensed access. The firm maintains an extensive cybersecurity insurance policy. This should cover expenses connected with forensic investigations, legal actions, business interruptions, and even possible regulatory fines that are under deductibles and policy limits.
Affected individuals should stay alert for any unusual activity linked to communications or accounts from Logitech or its partners. The company says it did not store any highly sensitive data in the affected system, so these individuals currently face a low level of risk.
However, experts advise that while investigations are ongoing, all affected parties should ensure to keep communications with Logitech. Also, experts advise that all affected individuals should ensure to employ all precautionary measures, such as watching their account statements for any suspicious activity. Lastly, cyber professionals caution that such parties should be diligent in identifying potential phishing emails.
