Advanced StrongPity Hackers Target Syria and Turkey with Retooled Spyware

Cybersecurity scientists now uncovered new specifics of watering hole assaults against the Kurdish neighborhood in Syria and Turkey for surveillance and intelligence exfiltration functions.

The superior persistent threat powering the operation, identified as StrongPity, has retooled with new tactics to handle compromised devices, cybersecurity agency Bitdefender explained in a report shared with The Hacker News.

“Applying watering gap ways to selectively infect victims and deploying a a few-tier C&C infrastructure to thwart forensic investigations, the APT team leveraged Trojanized preferred resources, this kind of as archivers, file recovery purposes, remote connections apps, utilities, and even stability program, to cover a wide vary of options that focused victims may be in search of,” the scientists explained.

With the timestamps of the analyzed malware samples applied in the campaign coinciding with the Turkish offensive into north-jap Syria (codenamed Operation Peace Spring) past October, Bitdefender reported the assaults could have been politically motivated.

Making use of Tainted Installers to Fall Malware

StrongPity (or Promethium) was to start with publicly noted on in Oct 2016 after assaults from buyers in Belgium and Italy that utilised watering holes to provide destructive variations of WinRAR and TrueCrypt file encryption computer software.

Due to the fact then, the APT has been connected to a 2018 procedure that abused Türk Telekom’s network to redirect hundreds of people in Turkey and Syria to malicious StrongPity variations of authentic program.

Therefore when the targeted users attempt to download a authentic application on the official web site, a watering gap attack or an HTTP redirect is carried out to compromise the programs.

Final July, AT&T Alien Labs discovered evidence of a fresh spyware marketing campaign that exploited trojanized versions of WinBox router administration software program and WinRAR file archiver to put in StrongPity and converse with the adversary infrastructure.

The new assault approach discovered by Bitdefender stays the identical: concentrate on victims in Turkey and Syria applying predefined IP checklist by leveraging tampered installers — including McAfee Stability Scan Additionally, Recuva, TeamViewer, WhatsApp, and Piriform’s CCleaner — hosted on localized software program aggregates and sharers.

“Interestingly, all information investigated pertaining to the tainted programs seem to have been compiled from Monday to Friday, for the duration of normal 9 to 6 UTC+2 functioning hours,” the researchers claimed. “This strengthens the concept that StrongPity could be a sponsored and arranged developer workforce compensated to produce sure ‘projects.””

As soon as the malware dropper is downloaded and executed, the backdoor is put in, which establishes conversation with a command and control server for doc exfiltration and for retrieving instructions to be executed.

It also deploys a “File Searcher” part on the victim’s device that loops via every single travel and seems for information with specific extensions (e.g., Microsoft Office environment paperwork) to be exfiltrated in the type of a ZIP archive.

This ZIP file is then break up into many concealed “.sft” encrypted files, sent to the C&C server, and ultimately deleted from the disk to go over any tracks of the exfiltration.

Growing Past Syria and Turkey

Whilst Syria and Turkey may perhaps be their recurring targets, the risk actor guiding StrongPity seems to be increasing their victimology to infect consumers in Colombia, India, Canada, and Vietnam making use of tainted variations of Firefox, VPNpro, DriverPack, and 5kPlayer.

Calling it StrongPity3, Cisco Talos scientists yesterday described an evolving malware toolkit that employs a module identified as “winprint32.exe” to launch the doc research and transmit the gathered information. What is actually a lot more, the pretend Firefox installer also checks if either ESET or BitDefender antivirus computer software is put in before dropping the malware.

“These qualities can be interpreted as signals that this threat actor could in point be section of an business assistance for seek the services of procedure,” the scientists explained. “We feel this has hallmarks a skillfully packaged alternative due to the similarity of every piece of malware remaining incredibly similar but used across diverse targets with minimal adjustments.”
