More than two months after the discovery of an organized malware campaign targeting dozens of companies in the defense and chemical industries, the espionage hack attack shows no signs of letting up.
According to a blog post published on Monday, the same group that targeted at least 38 companies between July and September is continuing its assault with emails that attempt to trick recipients at sensitive companies into installing backdoor trojans on their employer-issued computers. In the latest iteration, the emails contain a malicious attachment of the very document Symantec issued in late October warning of the so-called Nitro attacks.
“Despite the publishing of the whitepaper, this group persists in continuing their activities unchecked,” Symantec researchers Tony Millington and Gavin O’Gorman wrote. “They are using the exact same techniques – even using the same hosting provider for their command and control (C&C) servers.”
