A ransomware group named ShinyHunters claimed a data breach involving Cisco Systems, Inc. in April 2026. The group claimed to have accessed over 3 million Salesforce records containing personally identifiable information (PII), GitHub repositories, AWS buckets, and other internal corporate data. Cisco has not officially confirmed this breach, and available research focuses on product vulnerabilities rather than a confirmed data compromise.
The alleged breach may have involved PII, GitHub repositories, and AWS credentials, according to the ransomware group. However, there is no public information on the specific types of PII affected or the precise number of individuals impacted. Cisco has not made any statements regarding data types or the affected population.
Details about this alleged incident can emerge later, and official notices from Cisco may be delayed.
