New Ted Backdoor Hides Inside Victims' Own HAProxy Builds to Intercept Web Traffic

A newly discovered Linux implant dubbed 'Ted' was compiled directly into victims' HAProxy binaries in South Korea, intercepting and altering web traffic — a build-pipeline supply-chain attack that evades conventional file-integrity monitoring.

A previously undocumented Linux toolkit has been found compiled directly into the trojanized HAProxy load balancers of two South Korean organizations, where it intercepted web traffic and served altered pages to selected visitors.

The attackers named the implant ted in debug strings left in the binary. It is not a HAProxy vulnerability, and installing it requires code execution on the host and

Editorial Analysis

Why it matters

Build-time implants in core infrastructure software like load balancers can persist undetected for months, undermining trust in self-compiled open-source components.

What to do

Verify cryptographic hashes of all self-built infrastructure binaries against reproducible-build references and integrate binary attestation into CI/CD.

Board brief

Attackers embedded malware directly inside a widely used load-balancer's compiled code, a supply-chain technique that could affect any organisation building open-source infrastructure from source.
