One hundred fifty two Chrome extensions with malware generate fake traffic

Published on June 15, 2026 | Translated from Spanish

A recent investigation has uncovered 152 Chrome extensions, accumulating over 105,000 installations, that operate as fake traffic generators and unwanted advertising. Disguised as harmless wallpapers, these applications slow down the browser and expose users to intrusive ads. The lesson is simple: installing extensions without verifying their source can compromise device performance and personal privacy.

browser window crowded with 152 small extension icons, one icon glowing red and cracking like a broken screen, fake wallpaper thumbnails bleeding into pulsing advertisement streams, CPU usage graph spiking red in corner, network activity lines branching into fake traffic nodes, chrome logo dimmed and surrounded by warning symbols, cinematic technical illustration, dark cyberpunk palette, neon red and blue highlights on code strings, realistic browser UI with glitch effects, dramatic overhead lighting on keyboard with dust particles, photorealistic digital forensics render

How these malicious scripts operate in the browser 🔍

These extensions act as intermediaries, injecting scripts that redirect user traffic to servers controlled by attackers. In doing so, they generate fake ad clicks and collect browsing data without consent. The code, often obfuscated, runs in the background consuming system resources. For developers, this case underscores the need to audit requested permissions and avoid downloading suspicious packages from unofficial stores, where security review is minimal.

The wallpaper that sells you everything, including the kitchen sink 🖼️

Who would have thought that putting a nice landscape photo on your desktop would end up turning your browser into a slot machine. It turns out those free wallpapers not only decorated your screen, but also filled your history with ads for things you never wanted to buy. In the end, the price of free isn't your attention, but rather your PC starting to run as if it had 20 Chrome tabs open. Good thing there were only 105,000 unsuspecting victims.
