🧨 Sound the Alarm: These Chrome Extensions Are Sleeper Threats

Google Chrome users—especially businesses—face a new and dangerous risk.

A silent network of malicious Chrome extensions has just been exposed, potentially impacting millions.

According to cybersecurity researchers at LayerX, four extensions are actively masquerading as sound tools while quietly waiting to execute malicious code.

These are the extensions you should delete

immediately

:

• Sound Booster
• Examine source code of Volume Max – Ultimate Sound Booster
• Volume Master: Master Your Sound
• Volume Booster: Ultimate Sound Enhancer

These aren’t your everyday privacy nuisances—they’re sleeper agents built by a coordinated developer or group, with shared code and links to known malicious domains.

Why Should Small Businesses Care?

Most SMBs don’t restrict browser extensions across their teams. If even one employee installs a rogue plugin, your entire network could be exposed. These extensions can:

• Steal cookies, saved passwords, and session data
• Bypass endpoint detection tools
• Act like modern botnets, but from within your employee’s browser

Don’t Wait for a “Marching Order”

These sleeper extensions haven’t “activated” yet—but when they do, it’s too late to contain the damage. The time to harden your defenses is now, not after the breach report.
