Moderate risk — monitor and plan remediation
Basically, a harmful JavaScript file was sent in a phishing email, but not many antivirus programs caught it.
A malicious JavaScript file named cbmjlzan.JS was found in a phishing email. Only 15 antivirus programs flagged it, raising concerns about detection. Stay vigilant against such threats.
What Happened
A piece of JavaScript code was discovered embedded in a phishing email. This code was packed within a RAR archive and named cbmjlzan.JS. The file's SHA256 hash is a8ba9ba93b4509a86e3d7dd40fd0652c2743e32277760c5f7942b788b74c5285.
How It Works
The JavaScript file is designed to execute malicious actions once opened. Phishing emails often use such techniques to trick users into downloading harmful content. In this case, the obfuscation of the JavaScript code may have contributed to its low detection rate.
Who's Being Targeted

Signs of Infection
If a user inadvertently opens the RAR archive and executes the JavaScript file, they may notice unusual behavior on their device. This could include unexpected pop-ups, slow performance, or unauthorized access to personal information.
