A CISO's Guide to Infostealers: Prevention and Detection
TechTarget, Monday, June 22nd, 2026
CISOs can counter rising infostealer malware through stronger incident response and layered prevention controls.
Infostealers are not new, but it has become easy for anyone regardless of skill to use them at scale via malware-as-a-service botnets.
They infect endpoints through phishing, malicious links, social engineering, and drive-by downloads to steal credentials and financial data.
Organizations should update incident response plans for widespread attacks hitting many endpoints at once.
Prevention requires layered defenses including user training, antimalware, patching, monitoring, least privilege, and MFA.
Encrypting sensitive data at rest and limiting browser autofill further reduce attack effectiveness.
