How to remove CoffeeLoader

What is CoffeeLoader

CoffeeLoader is a sophisticated malware loader known for deploying additional malicious software while adeptly evading detection. It employs advanced techniques such as call stack spoofing, sleep obfuscation, and GPU-based execution, allowing it to bypass security measures effectively. A key feature of this malware is its use of a packer called “Armoury”, which operates code on the system’s GPU, complicating analysis and enhancing evasion in virtual environments. CoffeeLoader stays connected to its command and control (C2) servers using a domain generation algorithm (DGA), which generates new domains if primary channels are disrupted. It also uses certificate pinning to prevent TLS man-in-the-middle attacks, maintaining secure communications. Sharing similarities with SmokeLoader, CoffeeLoader utilizes process injection, import resolution by hash, and network traffic encryption with hardcoded RC4 keys. Cybercriminals often leverage it to distribute Rhadamanthys malware, an information stealer that targets device data and cryptocurrency wallets. As a result, CoffeeLoader poses significant risks, including identity theft, financial loss, and potential system compromise.

How CoffeeLoader infected your system

CoffeeLoader is a sophisticated malware loader that infiltrates computers using a blend of deceptive tactics and advanced techniques to evade detection. Cybercriminals often embed it within pirated software, key generators, or cracked tools, tricking users into downloading and executing malicious files. Additionally, CoffeeLoader spreads through phishing emails with deceptive attachments or links, exploiting software vulnerabilities to gain entry into systems. Once inside, it employs advanced methods such as call stack spoofing and GPU-based execution to avoid antivirus detection. The malware further ensures persistent communication with its command and control servers using a domain generation algorithm, which helps it stay connected even if primary channels are disrupted. By remaining stealthy and adaptable, CoffeeLoader poses a significant threat, often delivering other malicious payloads like Rhadamanthys, leading to potential data breaches and financial loss.
