S1deload Stealer is a cunning information-stealing malware, which spreads through social engineering tactics via deceptive comments on Facebook pages containing enticing adult-themed archives.
Once infiltrated, it deploys a twin-sided strategy: a seemingly legitimate executable with Western Digital’s digital signature, coupled with a concealed malicious DLL (WDSync.dll). This duo orchestrates a range of insidious actions, from pilfering login credentials and cookies to mining BEAM cryptocurrency. S1deload embodies the intersection of artful propagation and multifaceted cyber exploits.

Technical Analysis of S1deload Malware
Upon gaining a foothold on a targeted device, S1deload uses wide array of functions. But first, it establishes a connection with its command-and-control server, following the instructions from the config. Among its main functions supplementary components downloading and execution. Initial payload has only bare minimum of functions needed to make things happen. Additional modules are what make all the functionality S1deload has. A notable example is the deployment of a headless Chrome web browser, designed to operate surreptitiously in the background and replicate human browsing patterns. This operational scheme serves the purpose of artificially inflating engagement metrics, such as view counts, on social media content like YouTube videos and Facebook posts.
S1deload also demonstrates the capability to introduce a data-stealing module, enabling the extraction of stored login credentials and cookies from the victim’s browser, along with data retrieved from the Login Data SQLite database. Moreover, it boasts the capacity to implant a cryptojacking module dedicated to mining the BEAM cryptocurrency. The purloined credentials play a dual role: they empower the malware author to propagate the malware across social media channels, while concurrently perpetuating the infection cycle.
Upon the successful compromise of a Facebook account, S1deload takes a step further by embarking on an assessment of the account’s potential value. To undertake this evaluation, the malware capitalizes on the Facebook Graph API, probing factors such as the victim’s administrative privileges over a Facebook page or group, involvement in paid advertisements, and connections to a business manager account.
The infiltration of S1deload to the target system is commonly done through the use of social engineering maneuvers. They effectively deceive the victim, make them think every piece of the offer is legit. This process was initiated by cybercriminals who adeptly exploited the comments section of Facebook pages, orchestrating a bait-and-hook strategy. The bait comprised seemingly innocuous archive files with enticing names like AlbumGirlSexy.zip, HDSexyGirl.zip, and SexyGirlAlbum.zip. Deceptively masked within these archives were the underlying threats.
Upon downloading these archives, unsuspecting users were confronted with a dual-pronged assault. The first component was an executable file adorned with a seemingly legitimate digital signature from Western Digital, thereby lending an air of credibility. However, concealed within the same package lay the sinister WDSync.dll, a malicious DLL that served as the delivery vessel for the actual malware, S1deload.
