CustomLoader Malware Infiltrates Vulnerable Computers
CustomLoader is a type of malware that is specifically designed to initiate chain infections by loading additional malicious components and programs onto compromised devices. It has been observed that CustomerLoader infections typically rely on the DotRunpeX injector trojan to infiltrate the final payload. The utilization of this technique has facilitated the proliferation of over forty malware families.
The existence of CustomerLoader came to the attention of the cybersecurity community in June 2023, although there is evidence suggesting that this malware may have been active as early as May of the same year. The diverse distribution methods employed by CustomerLoader indicate that the developers may be offering it as a service, making it accessible to multiple threat actors.
How does CustomerLoader function?
To ensure its effectiveness, CustomerLoader incorporates various anti-detection and anti-analysis techniques. The malware disguises itself as a legitimate application and utilizes obfuscated code. Additionally, it employs tactics to evade detection by antivirus tools, further complicating its identification.
Once successfully infiltrated, CustomerLoader proceeds to load the DotRunpeX injector malware. Similar to CustomerLoader, DotRunpeX also employs multiple techniques to avoid detection. Through the utilization of DotRunpeX, CustomerLoader has been observed facilitating the distribution of various malware families, including loaders, Remote Access Trojans (RATs), data stealers, and ransomware.
The final payloads delivered by CustomerLoader encompass a wide range of malicious software, some of which include Amadey, LgoogLoader, Agent Tesla, AsyncRAT, BitRAT, NanoCore, njRat, Quasar, Remcos, Sectop, Warzone, XWorm, DarkCloud, Formbook, Kraken, Lumma, Raccoon, RedLine, Stealc, StormKitty, Vidar, as well as WannaCry variants and Tzw ransomware.
It is crucial to recognize that high-risk malware infections can have severe consequences, including diminished system performance or failure, data loss, privacy breaches, financial losses, and even identity theft. Therefore, if there is a suspicion of CustomerLoader infection, or any other type of malware, it is imperative to promptly conduct a comprehensive system scan using antivirus software and remove all identified threats to mitigate potential damage.
