A hacker repeatedly attempted to access Cisco’s corporate network.
Cisco acknowledged that the hacker aimed to encrypt files, Bloomberg reports.
Cisco became aware after the hacker leaked a list of the files it had stolen on the dark web.
An investigation determined that the hacker broke into Cisco’s network by cracking into an employee’s personal Google account, which synchronized their saved passwords across the web.
Cisco had “not identified any evidence suggesting that the attacker gained access to critical internal systems.
Investigators believe an adversary conducted the attack previously identified for several notorious cybercrime groups UNC2447, Lapsus$, and Yanluowang ransomware operators.
UNC2447 targeted organizations with ransomware in Europe and North America as per Mandiant cybersecurity firm.
Yanluowang, a ransomware variant, has targeted U.S. corporations since August 2021, according to Symantec.
Price Action: CSCO shares closed higher by 2.45% at $46.02 on Wednesday.
