How to remove InvisibleFerret

What is InvisibleFerret

InvisibleFerret is a sophisticated Python-based backdoor malware linked to North Korean threat actors, primarily designed for data theft and the injection of additional malicious tools. Its initial operation involves gathering geolocation and system details, including the OS version, hostname, and username, followed by generating a unique ID for the infected system. This malware organizes its targets into specific lists to efficiently identify valuable data for exfiltration, bypassing less important files and directories. It enables attackers to remotely execute commands, download additional payloads, and potentially install AnyDesk, a legitimate remote administration tool, for further control. InvisibleFerret is known for targeting browser data from popular browsers and extracting information from crypto wallets, authentication apps, and password managers. Its capabilities extend to monitoring clipboard activity and capturing keystrokes, allowing cybercriminals to steal sensitive information like passwords, banking details, and cryptocurrency credentials. Victims of this malware face significant risks, including identity theft, monetary loss, and further system infections.

How InvisibleFerret infected your system

InvisibleFerret is a sophisticated backdoor malware that primarily infiltrates computers through deceptive methods often involving social engineering tactics. Cybercriminals frequently target professionals in tech, finance, and cryptocurrency sectors by setting up fake job interviews, where victims are tricked into downloading malicious files disguised as coding challenges or video call software. This malware can also be distributed via infected email attachments, malicious advertisements, or deceptive websites, making it crucial for users to exercise caution while downloading files or clicking on links. Once a user unwittingly installs the malicious file, InvisibleFerret begins its operation by gathering system details and establishing a foothold in the infected system. It evades detection and executes its payload by establishing remote connections, allowing attackers to steal sensitive data, such as browser credentials and cryptocurrency wallet information. To prevent infiltration, it is essential to maintain updated security software, practice vigilant browsing habits, and avoid interacting with suspicious emails or websites.
