The silent epidemic no one talks about

Every day, millions of employees browse the web, use personal devices, download free software, and click links. None of them know they are being watched. Infostealer malware — credential-harvesting tools used by sophisticated threat actors — has become one of the most pervasive and underreported threats facing enterprises today.

Unlike ransomware, which announces itself with catastrophic disruption, infostealers work in total silence. They hide inside legitimate-looking applications, browser extensions, cracked software, and phishing payloads. Once installed, they steal with devastating efficiency: passwords, session cookies, autofill data, cryptocurrency wallets, VPN credentials, internal application tokens — then they vanish, often leaving no obvious trace on the endpoint.

The stolen data does not sit idle. Within hours it is packaged, sorted, and uploaded to underground marketplaces and channels where ransomware gangs, initial access brokers, and espionage buyers purchase it in bulk. An employee's corporate login, harvested from a home PC, can be listed for less than the cost of a coffee.

This is not theoretical. Researchers estimate that over 100 million credentials were stolen by infostealers in a single year, with a large share tied to enterprise environments. The question is not whether exposure exists — it is whether you discover it before an attacker acts.
