How Cuiall Apps Works
The “Cuiall Apps” application functions as a dropper for Legion Loader, a malicious tool designed to infiltrate devices with various types of malware. After it infects a system, Legion Loader can lead to multiple types of infections, including:
- Trojans: Malicious programs that can provide attackers with remote access to your system, allowing them to steal data or take control of your device.
- Ransomware: Malware that encrypts your files and demands payment (a ransom) in exchange for the decryption key.
- Data Stealers: Programs that steal sensitive information such as login credentials, financial data, and personal details.
- Cryptocurrency Miners: Malicious software that uses your computer’s processing power to mine cryptocurrencies for the attacker.
Moreover, Cuiall Apps often installs alongside a fake “Save to Google Drive” browser extension. This extension not only interferes with browser functionality but also tracks users’ browsing activities, steals email contents, and may even modify the browser into an HTTP proxy, opening up the system to further abuse.

If Cuiall Apps has infected your device, you may notice the following signs:
- Unrecognized Programs: You might notice new programs installed that you don’t remember downloading.
- Intrusive Pop-up Ads: These ads may appear while browsing websites or may seem unrelated to your browsing activities.
- Browser Redirects: Your browser may redirect you to unfamiliar websites or suspicious landing pages.
- Slow System Performance: The presence of malware often causes system sluggishness or freezing, especially during online activity.
- Changes in Browser Appearance: The fake browser extension can alter your browser settings or appearance without your consent.
