Hacker gained access to our network through a work Google account: Cisco

Networking giant Cisco has admitted a cyber-security breach via the “successful compromise” of an employee’s personal Google account, saying that no data was compromised.

The company’s own Cisco Talos threat research arm stated in a blog post that the attacker carried out a series of sophisticated voice phishing attempts in an effort to persuade the victim to accept multi-factor authentication (MFA) push notifications initiated by the attacker. The event happened in May, and the company has been attempting to address the attack ever since.
