In his career-ending extramarital affair that came to light in 2012, General David Petraeus used a stealthy technique to communicate with his lover Paula Broadwell: the pair left messages for each other in the drafts folder of a shared Gmail account. Now hackers have learned the same trick. Only instead of a mistress, they’re sharing their love letters with data-stealing malware buried deep on a victim’s computer.
Here’s how the attack worked in the case Shape observed: The hacker first set up an anonymous Gmail account, then infected a computer on the target’s network with malware. (Shape declined to name the victim of the attack.) After gaining control of the target machine, the hacker opened their anonymous Gmail account on the victim’s computer in an invisible instance of Internet Explorer—IE allows itself to be run by Windows programs so that they can seamlessly query web pages for information, so the user has no idea a web page is even open on the computer.
With the Gmail drafts folder open and hidden, the malware is programmed to use a Python script to retrieve commands and code that the hacker enters into that draft field. The malware responds with its own acknowledgments in Gmail draft form, along with the target data it’s programmed to exfiltrate from the victim’s network. All the communication is encoded to prevent it being spotted by intrusion detection or data-leak prevention. The use of a reputable web service instead of the usual IRC or HTTP protocols that hackers typically use to command their malware also helps keep the hack hidden.
