How to remove ResolverRAT

What is ResolverRAT

ResolverRAT is a sophisticated Remote Access Trojan (RAT) designed to stealthily infiltrate computer systems and grant attackers remote control capabilities. This malware is known for its advanced evasion techniques, including anti-analysis features that detect virtual environments and sandboxes, as well as heavy code obfuscation and encryption to avoid detection by security software. It commonly uses DLL side-loading to execute its malicious payload, leveraging legitimate applications to bypass system defenses. Once installed, ResolverRAT can exfiltrate sensitive data, breaking down large files into smaller chunks to ensure successful data theft. Its multifunctional nature allows it to perform a variety of malicious actions, such as keylogging, screen capturing, and even injecting additional malware. Typically distributed through phishing campaigns and malicious email attachments, ResolverRAT poses significant risks to both individuals and organizations, leading to potential data breaches and financial losses. Being proactive with security measures, such as keeping software updated and using reputable antivirus solutions, is crucial to mitigating the threat posed by this malware.

How ResolverRAT infected your system

ResolverRAT, a sophisticated Remote Access Trojan (RAT), primarily infiltrates computers through targeted phishing campaigns. Attackers craft highly tailored emails, often designed in the native languages of the recipients, to lure employees within specific sectors, such as healthcare and pharmaceuticals. These emails contain malicious links or attachments disguised as legitimate documents, which, when opened, execute the infection process. ResolverRAT employs the DLL side-loading technique, leveraging legitimate applications to execute its malicious payload without raising immediate suspicion. This malware is further equipped with anti-analysis capabilities, detecting virtual machines and sandbox environments to avoid detection. Such advanced distribution and evasion tactics make ResolverRAT a formidable threat, emphasizing the need for vigilance and robust cybersecurity measures.
