Infostealer Malware Trend 2026

Infostealer malware is a stealthy cyberweapon designed to silently harvest sensitive data—passwords, cookies, credit card numbers, and crypto wallets—from infected devices. Attackers deploy it via phishing emails, fake downloads, or compromised websites, then sell the stolen credentials on dark web marketplaces. Cybercriminals and state-sponsored hackers benefit, using this information for identity theft, financial fraud, or launching further targeted attacks.
