Fileless malware operates stealthily within networks, utilizing legitimate system tools like PowerShell and Windows Management Instrumentation (WMI) to execute malicious code in memory without leaving traces on disk. Traditional antivirus solutions struggle to detect these threats due to their reliance on file signatures. The primary vector for fileless malware is email, where attackers use spoofed messages to trick users into activating malicious scripts. Misconfigurations in Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records create vulnerabilities that attackers exploit to deliver spoofed emails. Traditional endpoint protection mechanisms are inadequate against fileless attacks, necessitating a shift towards behavioral analysis for detection. Organizations must assess their preparedness by ensuring proper email authentication configurations and enhancing endpoint security capabilities. Integration among security teams and updated employee security awareness programs are also essential. Sendmarc helps organizations mitigate vulnerabilities by providing visibility into SPF, DKIM, and DMARC configurations and enforcing DMARC to block unauthenticated messages.
