Infostealers are gaining attention as a dangerous form of malware that compromises systems to harvest sensitive information. With billions of credentials exposed in 2024 alone, around 4.3 million machines have reportedly been infected globally. These malware variants operate stealthily, making them highly effective at capturing browser passwords, autofill data, and session cookies. The rise of malware-as-a-service has enabled easier access for attackers, escalating the threat level. Phishing campaigns utilizing sophisticated infostealers have been recently observed, showcasing the continual evolution and growing sophistication of these cyber threats.
Infostealers are highly effective due to their small size, speed and ability to operate stealthily, making them often go undetected.
Once on the device, the malware collects browser passwords, credit card numbers, addresses, cryptocurrency wallet data, and cookies, sending it to attacker-controlled servers.
