To bypass watermarks and grab videos that have downloads disabled, millions of users turn to a video downloader without watermark via desktop web browsers. That search has created a playground for cybercriminals. In April 2026, security researchers at Cybernews identified multiple malicious Chrome extensions operating in the Chrome Web Store, which had quietly infected more than 130,000 users.
These rogue extensions promised one-click, high-definition downloads directly from the desktop TikTok interface. Under the hood, they injected malicious JavaScript payloads into active browser sessions. Rather than merely parsing the MP4 source link, these tools harvested authentication cookies, session tokens, and compromised user credentials across secondary tabs, including social media profiles and webmail clients.
Spyware downloader risks represent the most severe danger facing casual social media users today. Free software that purports to strip watermarks frequently bundles tracking scripts, adware injection engines, or credential stealers. Once installed, these tools run with broad permissions, capable of reading and modifying data across every site you visit.
