What is Fabookie malware?

Fabookie is a malicious software categorized as an information stealer. It primarily targets Facebook Business accounts, aiming to steal sensitive data like login credentials and account information.

This stolen data can then be exploited by attackers for various malicious purposes. Fabookie operates discreetly, running silently in the background without the user's knowledge, making it a significant threat to unsuspecting victims.

Fabookie primarily targets devices running 64-bit operating systems. Security researchers estimate over 100,000 infected machines worldwide, highlighting its widespread reach.

Technical details of the Fabookie malicious software

The primary capabilities of Fabookie include:

  • Credential theft (T1552): Fabookie searches infected machines for saved passwords, browser cookies containing login sessions, and other cached authentication information.
  • System information gathering (T1518): Beyond credentials, Fabookie may gather details about the system it infects. This information, such as installed software and hardware specifications, could be used to further exploit vulnerabilities or tailor future attacks.
  • Facebook Interaction (T1071): Once it acquires credentials, Fabookie interacts with the Facebook API. This allows the malware to extract additional information about the targeted Facebook Business account, including payment methods and account balances.
  • Command-and-Control Communication: The stolen data is then transmitted to a remote server controlled by the attackers.

Similar to other malware families, such as Amadey and RisePro, Fabookie is capable of ensuring persistence on the system by remaining active even after a reboot.

One notable feature of Fabookie is that it exploits .jpeg images to deliver malicious code.

Execution process of Fabookie

Let’s observe the execution process of the Fabookie malware by uploading its sample to ANY.RUN for analysis.

The Fabookie stealer infiltrates systems through various means such as malicious websites or phishing emails. Once installed, it silently collects sensitive information like login credentials and credit card details from the infected device. This data is then transmitted to remote servers controlled by the attackers. To remain undetected, Fabookie employs persistence techniques and may allow remote access for further malicious activities.

In our example, the execution chain of this stealer is straightforward. Once Fabookie initiates its own child process, it proceeds with its malicious activities centered around stealing credentials, cookies, and other valuable information from web browsers. The stealer collects this data and sends it to the C2 (Command and Control) server for remote access and further exploitation.

Overall, the execution chain of the Fabookie stealer is designed to silently compromise systems, steal valuable data, and maintain control for as long as possible without raising suspicion.

Distribution methods of the Fabookie malware

Attackers employ various ways of distributing Fabookie. One of the most common ones is via special loader malware that first penetrates defense systems of endpoints and delivers Fabookie to them. NullMixer and SmokeLoader are two examples of such loader malware.

Alternatively, Fabookie can be spread through spam emails that are crafted in a way to appear legitimate to users. These emails usually contain phishing links and files which eventually lead to the infection with Fabookie.


Fabookie is just one example of the ever-evolving threat landscape. By understanding its capabilities and implementing these protective measures, you can significantly reduce your risk of falling victim to such attacks and safeguard your sensitive information.

The ANY.RUN sandbox provides a cloud-based environment for analyzing files and links suspected of being malicious. It effectively identifies threats like Fabookie and generates reports summarizing the detected malware's technical characteristics, including TTPs and IOCs.
