How Hackers Exploit Windows Administrative Shares

The Huntress post describes ongoing outbreaks of worm-like malware families (Emotet, Trickbot, Qakbot) that propagate internally by abusing Windows Administrative Shares and stolen or brute-forced administrative credentials. It explains how these families use PsExec-style techniques to copy and execute payloads over SMB, highlights the risk posed by shared local administrator accounts and open internal SMB, and recommends mitigations including LAPS, reducing/admin auditing of privileged accounts, disabling admin shares where possible, and blocking SMB via host firewalls.
