How Did FadeStealer Infiltrate My Computer?
Currently, it is believed that cybercriminals approach targets through spear phishing emails containing a regular password-protected document accompanied by a disguised CHM malware file labeled as a password file.
According to ASEC, the phishing emails employ tactics to entice individuals into opening the CHM file in order to obtain the document password, thereby infecting their Windows computer.
Essentially, the threat actor compresses the password-protected document along with the CHM malware, deceiving users into thinking that executing the CHM file is necessary to access the protected document.
Upon executing the CHM file, users gain access to the password information. However, the internal script code within the CHM file initiates the execution of MSHTA.exe, resulting in the execution of a malicious script from the threat actor’s command and control (C&C) server.
How to Avoid Malware Installation
To minimize vulnerabilities, it is crucial to keep your operating system and software up to date. When dealing with email attachments or encountering suspicious links, particularly from unfamiliar or untrusted sources, exercise caution and remain vigilant. Utilize trusted antivirus or anti-malware software and regularly scan your system to detect and mitigate potential threats.
Adopt safe browsing practices, which include refraining from downloading files from untrusted websites and being cautious of pop-up ads or deceptive download buttons. By implementing these measures, you can enhance your overall cybersecurity posture and protect yourself from online risks.
