Azari Jahromi said it is not clear which individual or organization launched the cyber attack. At present, 95% of attacked routers have returned to normal.
According to Reuters, hackers attacked by using a vulnerability in Cisco routers. The company earlier issued warnings and updated patches. However, some companies have not yet installed patches.
Cisco’s Talos Security Intelligence and Research Group researcher Nick Biasini posted a blog on Thursday (April 5th) saying that several (hacking) incidents occurred in multiple countries, including some attacks specific to critical infrastructure involve loopholes in smart installation protocols. “As a result, we are taking an active stance, and are urging customers, again, of the elevated risk and available remediation paths.”
On Saturday night, Cisco stated that the above message is to identify weaknesses for customers and eliminate the threat of cyber attacks.
Cisco is the world’s largest router vendor. In September 2015, multinational Cisco routers were hacked and stolen from massive amounts of information.
