Hacker breached our network via employee 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 attacker conducted a series of sophisticated voice phishing attacks under the guise of various trusted organisations attempting to convince the victim to accept multi-factor authentication (MFA) push notifications initiated by the attacker, the company’s own Cisco Talos threat research arm revealed in a blog post.
