From: Operation Hangover: Unveiling an Indian Cyberattack Infrastructure
On Sunday March 17th 2013 the Norwegian newspaper Aftenposten reported that the telecommunications giant Telenor had filed a case with Norwegian criminal police (“KRIPOS”) over what was perceived as an unlawful intrusion into their computer network. The infection was reported to have been conducted via “spear phishing” emails sent to people in the upper tiers of management.
Initially, we had no information or visibility into this case. However, after some time Norwegian CERT (NorCERT) shared some data from the event, which included md5 hashes of malicious files and information about which Command and Control servers were used.
