Major Technology Vendor Compromised by ShinyHunters Threat Group

Cisco suffered a significant breach by the ShinyHunters threat actor group, resulting in theft of source code and sensitive data. This incident highlights the critical risk that supply chain compromises pose to enterprise security, as attacks against major vendors can cascade to affect thousands of downstream customers.
