“Most organizations running WINS today probably aren’t actively using it for anything critical. They’ve just never had a compelling reason to turn it off,” he said. “It’s been quietly replicating in the background, consuming minimal resources, causing no obvious problems. That’s the nature of legacy infrastructure: It persists not because it’s needed, but because removing it requires effort and carries risk, while leaving it alone is free,” said Wright.
WINS is a security risk
WINS had major design limitations that made it a security risk, said Wright. “WINS has no mechanism to verify the legitimacy of name registrations, which makes it vulnerable to spoofing attacks,” said Wright.
“An attacker on the network can register malicious entries, including Web Proxy Auto-Discovery (WPAD) records to intercept web traffic, or redirect connections to systems they control. It’s a straightforward path for lateral movement,” he said.
