How Woiap WApp Works

Woiap WApp operates as a dropper, meaning its primary function is to introduce other malware into the system. Upon installation, it immediately downloads and deploys Legion Loader, which subsequently installs additional malicious software.

Legion Loader has been observed dropping various threats, including:

• Trojans (Backdoors) – Allow hackers to gain remote control over the infected system.
• Ransomware – Encrypts files and demands a ransom for decryption.
• Information Stealers – Extracts personal data, including banking credentials and stored passwords.
• Cryptominers – Uses system resources to mine cryptocurrency without user consent.
• Malicious Browser Extensions – Hijacks web browsers to track user activity, steal credentials, and turn devices into HTTP proxies.

Given its potential to severely compromise system security, removing Woiap WApp immediately is crucial.
