CustomLoader Malware
CustomerLoader is a threatening program that is specifically designed to facilitate chain infections on targeted devices. Its primary function is to load additional malicious components and programs onto compromised devices, thereby intensifying the impact of the attack. Notably, all identified instances of CustomerLoader infections have been found to rely on the DotRunpeX injector Trojan as the initial stage payload, paving the way for the deployment of the final payload. This has resulted in the proliferation of more than forty distinct malware families.
CustomLoader may be Offered in a MaaS (Malware-as-a-Service) Scheme
The existence of CustomerLoader first came to the attention of the cybersecurity community in June of 2023. However, there are indications that this malware had been actively operational since at least May of the same year, suggesting a potential period of sustained activity before its detection.
Given the diverse range of distribution methods observed with CustomerLoader, it is highly likely that the developers behind this malicious program offer it as a service to multiple threat actors. This implies that various cybercriminals or hacking groups can avail themselves of CustomerLoader's capabilities, contributing to its widespread use across different attack campaigns.
Cybercriminals Use the CustomLoader Malware to Deliver a Wide Range of Harmful Threats
CustomerLoader employs multiple sophisticated techniques to evade detection and analysis by security solutions. The program disguises itself as a legitimate application, utilizing obfuscated code to hinder efforts to uncover its threatening nature. Additionally, CustomerLoader implements various tactics specifically designed to bypass detection by antivirus tools and other security mechanisms.
Once successfully infiltrated, CustomerLoader proceeds to load DotRunpeX, which operates as an injector-type malware. DotRunpeX itself employs a range of anti-detection techniques, further complicating the identification and mitigation of the threat.
As previously mentioned, CustomerLoader campaigns, facilitated through DotRunpeX, have been observed to support more than forty distinct malware families. These include a wide range of malicious software such as loaders, Remote Access Trojans (RATs), data stealers and ransomware.
Some notable examples of final payloads associated with CustomerLoader campaigns (though not limited to these) include Amadey, LgoogLoader, Agent Tesla, AsyncRAT, BitRAT, NanoCore, njRat, Quasar, Remcos, Sectop, Warzone, XWorm, DarkCloud, Formbook, Kraken, Lumma, Raccoon, RedLin, Stealc, StormKitty, Vida and, various WannaCry variants, the Tzw Ransomware and others.
In summary, falling victim to high-risk malware infections facilitated by CustomerLoader can lead to significant consequences. These may include compromised system performance or failure, data loss, severe privacy breaches, financial losses, and even identity theft. It is crucial for users and organizations to implement robust security measures and remain vigilant against such threats to protect their systems, data, and overall digital well-being.
