Breached identities due to infostealer malware are a significant threat to corporate information security in 2024. Infostealers are a type of remote access trojan that exfiltrate sensitive data, including saved credentials, session cookies, browser history, crypto wallet information, screen captures, and host data. Infections often stem from downloading cracked software, malicious advertising, fake Windows updates, and repackaged games. Infostealers do not require local administrative privileges, making them easy to execute. Threat actors primarily aim to profit from breached bank accounts and crypto wallets, often bypassing multi-factor authentication by targeting session cookies. They also seek credentials for subscription services and corporate access. Research shows that 90% of breached companies had leaked corporate credentials in a stealer log, with 78% experiencing leaks within six months of a breach. In comparison, 76% of similar companies without breaches had experienced a corporate stealer log compromise. The investigation identified high-criticality credentials from various corporate applications, indicating that a single user often has access to multiple credentials. The rise of infostealer malware represents a broad threat, encompassing a wide range of sensitive data. Organizations are advised to implement strategies such as restricting download privileges, avoiding illegal content, disabling macros, and regularly updating software to mitigate risks associated with infostealer malware.
