What happened
Cybercriminals are increasingly using infostealer malware to steal credentials and gain access to legitimate business infrastructure, turning compromised websites into platforms for distributing additional malware. Once attackers access administrative portals, CMS platforms, or hosting servers, they can inject malicious code or redirect traffic, creating a self-sustaining loop that further propagates malware to end users. This tactic amplifies the impact of infostealer campaigns by weaponizing trusted infrastructure against unsuspecting visitors.
Who is affected
Businesses of all sizes with exposed administrative interfaces are at risk. Compromised websites can host malware that affects customers, partners, and employees, damaging trust and increasing legal and operational exposure. Organizations with weak credential management or insufficient monitoring are particularly vulnerable.
Why CISOs should care
Infostealer malware can escalate beyond endpoint compromise to leveraging trusted business infrastructure for malicious purposes. CISOs must address both endpoint threats and the risk that compromised internal systems could serve as malware distribution channels. Failure to secure infrastructure can result in widespread customer and partner impact, regulatory scrutiny, and reputational damage.
3 practical actions
-
Protect Credentials: Enforce strong passwords, multifactor authentication, and regular audits to minimize credential theft risk.
-
Secure Business Infrastructure: Harden web servers and CMS platforms with access controls, intrusion detection, and least-privilege principles.
-
Threat Intelligence & Monitoring: Monitor for stolen credentials and anomalous activity to respond quickly to prevent infrastructure misuse.
