What happened
Infostealer malware campaigns are expanding, with threat actors adopting new tactics to broaden their impact and steal sensitive information from victims. According to the report, analysts have observed a rise in the distribution of infostealers that deploy multiple data exfiltration methods, including harvesting browser credentials, system information, cryptocurrency wallets, and stored files. These campaigns make use of widely distributed lures — such as cracked software installers, phishing attachments, and malicious archives — to trick victims into executing the stealer payload. Once executed, the malware collects targeted data and transmits it to remote servers under attacker control. In some cases, operators have added obfuscation layers and modular capabilities that enable the infostealer to adapt to specific environments or evade detection on compromised systems.
Who is affected
Users and systems where the infostealer malware is successfully delivered and executed are affected, with attackers able to harvest sensitive credentials, personal data, wallet information, and other locally stored information.
Why CISOs should care
The expansion of infostealer campaigns highlights ongoing risk from data exfiltration threats, particularly where malware authors enhance delivery tactics, evasion techniques, and modular extraction capabilities that can capture a wide range of sensitive information.
3 practical actions
- Audit endpoint telemetry for exfiltration signs. Look for anomalous outbound connections matching infostealer communication patterns.
- Harden delivery vectors. Review email, download, and software distribution controls to block typical lures such as cracked installers.
- Monitor credential stores. Detect signs of unauthorized reading or copying of credential repositories and wallet files.
