The security researchers at Proofpoint have uncovered that the Iranian Hacking group, TA456 which is also known as “Tortoiseshell” and “Imperial Kitten” has recently executed several targeted attacks on defense contractors with malware.
On Facebook, the hackers of this group mimicked themselves as aerobics instructors simply to fool the defense contractors and then compromise their systems to exfiltrate sensitive data.
Here during the ongoing cyber espionage, the hackers mainly targeted the employees of the contractor companies working in the US aerospace defense; especially those who are involved in the operations in the Middle East.
