U.S. networking giant Cisco Systems has been hacked, the company confirmed on Wednesday, after Yanluowang ransomware operators claimed the attack on their leak site.
But according to Cisco’s Talos threat intelligence team, the breach resulted in the exfiltraton of inconsequential data and the booting of the attackers from Cisco’s systems and corporate network. They repeatedly try to get back in, the analysts said, but despite using various advanced techniques weren’t able to repeat their initial feat.
