Cisco Confirms Network Breach Via Hacked Employee Google Account

Cisco Systems has confirmed that it suffered from a network breach after attackers were able to gain access to an employee’s VPN client via a compromised Google account. The network giant released a statement on Wednesday addressing the security incident. The attack occurred in May and was perpetrated by the Yanluowang ransomware group, according to the results of an investigation conducted by Cisco after the attack.

Forensic details of the attack exposed the Yanluowant group as the culprit. The group has ties to both the UNC2447 and Lapsus$ cybercrime groups.
