A cyberespionage campaign aimed at aerospace and defense sectors in order to install data gathering implants on victims' machines for purposes of surveillance and data exfiltration may have been more sophisticated than previously thought.
The attacks, which targeted IP-addresses belonging to internet service providers (ISPs) in Australia, Israel, Russia, and defense contractors based in Russia and India, involved a previously undiscovered spyware tool called Torisma stealthily monitor its victims for continued exploitation.
Tracked under the codename of "Operation North Star" by McAfee researchers, initial findings into the campaign in July revealed the use of social media sites, spear-phishing, and weaponized documents with fake job offers to trick employees working in the defense sector to gain a foothold on their organizations' networks.

Not only did the campaign use legitimate job recruitment content from popular US defense contractor websites to lure targeted victims into opening malicious spear-phishing email attachments, the attackers compromised and used genuine websites in the US and Italy — an auction house, a printing company, and an IT training firm — to host their command-and-control (C2) capabilities.
"Using these domains to conduct C2 operations likely allowed them to bypass some organizations' security measures because most organizations do not block trusted websites," McAfee researchers Christiaan Beek and Ryan Sherstibitoff said.
