Largely undetected Mac malware suggests disgraced HackingTeam has returned

Researchers have exposed what seems to be newly evolved Mac malware from HackingTeam, a discovery that’s prompting speculation that the disgraced malware-as-a-provider company has reemerged the reason that the final July hack that spilled gigabytes worth of the institution’s non-public and source code.
The sample was uploaded on February 4 to the Google-owned VirusTotal scanning provider, which at the time showed it wasn’t detected with the aid of the important antivirus programs. (in advance of this report on Monday, it was seen through 10 of 56 AV services.)

A technical analysis posted Monday morning using SentinelOne protection researcher Pedro Vilaça showed that the installer turned into closing up to date in October or November, and an embedded encryption key dated October 16, 3 months after the HackingTeam compromise. The pattern installs a replica of HackingTeam’s signature remote Code systems compromise platform, the main Vilaça, to conclude that the outfit’s comeback generally is predicated on old, in large part unexceptional source code, despite the institution vowing in July that it would go back with new code.

“HackingTeam remains alive and kicking, but they’re nevertheless the identical crap morons as leaks have to display us,” Vilaça wrote. “if you are new to OS X malware opposite engineering, it is a nice sample to practice with. I was given my primary questions responded, so there’s nothing else exciting about this. After the leak, I forgot about those men :-).”

Patrick Wardle, a Mac protection professional at Synack, has also tested the sample and says that while it appears to put in a new edition of the vintage HackingTeam implant, it uses several superior hints to prevent detection and evaluation. For one, it uses Apple’s native encryption scheme to guard the contents of the binary document, making it the primary malicious implant installer Wardle has ever seen to accomplish that. Wardle changed into interrupting the encryption because Apple uses a static tough-coded key—” ourhardworkbythesewordsguardedpleasedontsteal(c)AppleC”—that has long been known to reverse engineering experts. Even then, he found that the installer was “packed” in a digital wrapper that still limited the variety of opposite engineering and evaluation he wanted to perform.



The sample still leaves many questions unanswered. For instance, it’s now unclear how the malware gets set up. One possibility is that objectives are tricked into believing the report installs a benign application. Any other opportunity is that it’s bundled with a make-the-most that surreptitiously executes the installer. People who want to know if a Mac is infected should check for a document named Bs-V7qIU.cYL dropped into the ~/Library/choices/8pHbqThW/ listing.

Vilaça said he could not conclusively determine that the new pattern is the work of HackingTeam. Since the 400 gigabytes of data obtained inside the July breach blanketed the remote Code structures source code, it’s viable that an extraordinary man or woman or organization recompiled the code and allotted it in the new installer. Still, Vilaça said proof from the Shodan seek carrier, and a test of the IP cope within VirusTotal display that a command and control server referenced in the sample turned into action as recently as January, suggesting that the new malware is greater than a mere hoax.
