Iranians hacked Navy network for four months? Not a surprise.
“Iranian hackers attacked NMCI in August of 2012, using a vulnerability in a public-facing website to gain initial access to the network. Because of a flaw in the security of the network the server was hosted on, attackers were able to use the server to gain access to NMCI’s private network and spread to other systems. While the vulnerability that allowed the attackers to gain access in the first place was discovered and closed by October, spyware installed by the attackers remained in place until November.”
