Scranos is a recently observed rootkit-enabled spyware trojan. It is still in development and its creators are regularly adding new components as well as improving existing functionality.
Bitdefender found the malware spreading through trojanized downloads that masquerade as real apps, like video players and e-book readers.
Scranos is delivered via cracked software downloads and illegitimate applications such as video players, drivers and anti-virus products. When opened, these applications install a signed rootkit driver, which is then used to maintain persistence and install further Scranos components.
Once installed, Scranos injects a downloader into a legitimate process which then communicates with a command and control server. It can then download various modules, providing it with a wide range of capabilities, including :-
- Extract cookies and steal login credentials from Google Chrome, Chromium, Mozilla Firefox, Opera, Microsoft Edge, Internet Explorer, Baidu Browser and Yandex Browser.
- Steal a user’s payment accounts from his Facebook, Amazon and Airbnb webpages.
- Send friend requests to other accounts, from the user’s Facebook account.
- Send phishing messages to the victim’s Facebook friends containing malicious APKs used to infect Android users as well.
- Steal login credentials for the user’s account on Steam.
- Exfiltrate browsing history.
- Silently display ads or muted YouTube videos to users via Chrome. We found some droppers that can install Chrome if it is not already on the victim’s computer.
- Subscribe users to YouTube video channels.
- Download and execute any payload.
