From Computerworld:

The gang behind Operation Hangover is believed to be based in India, and the bulk of the first round of cyber-espionage attacks, which were discovered in May, were aimed at its neighbor and long-time adversary Pakistan.

"After analyzing the payloads being used in this attack, we have identified that the targeted emails are part of an attack campaign known as Operation Hangover," Symantec said in a blog, referring to the newest campaign that relies on the Microsoft zero-day vulnerability to hijack and infect Windows PCs.
