MITRE ATT&CK

Techniques & procedures

10 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

2 techniques

T1059.004Unix ShellEvidence1

Through that channel, the operator can beacon, upload and download files, run shell commands, and replace the implant's configuration.

T1559Inter-Process CommunicationEvidence1

It writes the command body to a named pipe under /tmp. Zeroing the request channel afterwards leaves nothing to forward, and the command terminates at the load balancer.

Persistence

1 technique

T1554Compromise Host Software BinaryEvidence1

The toolkit was compiled directly into trojanized HAProxy load balancers... installing it requires code execution on the host and the ability to replace the running binary.

Stealth

3 techniques

T1070.002Clear Linux or Mac System LogsEvidence1

It then strips the keywords tmp, wget, cron and crond from root's bash history and from six system logs, among them auth.log and audit/audit.log.

T1070.003Clear Command HistoryEvidence1

It then strips the keywords tmp, wget, cron and crond from root's bash history.

T1070.006TimestompEvidence1

It overwrites the legitimate crond binary and gives the replacement the creation timestamp of /usr/bin/ssh.

Credential Access

1 technique

T1056Input CaptureEvidence1

A trojanized sshd in the same toolkit encrypts captured plaintext passwords and writes them to a fixed path.

Collection

1 technique

T1056Input CaptureEvidence1

A trojanized sshd in the same toolkit encrypts captured plaintext passwords and writes them to a fixed path.

Command and Control

2 techniques

T1071.001Web ProtocolsEvidence1

Output returns on the raw socket under a standard HTTP/1.0 200 OK header, which is what makes the exchange look like ordinary web traffic.

T1105Ingress Tool TransferEvidence1

Through that channel, the operator can beacon, upload and download files, run shell commands, and replace the implant's configuration.

Impact

1 technique

T1565.002Transmitted Data ManipulationEvidence1

It intercepted web traffic and served altered pages to selected visitors... The implant rewrites the content type and length on the way out, forces the response status to 200, and deletes the Accept-Ranges header.

New Linux toolkit found in trojanized HAProxy targeting South Korean organizations | brief | SC Media

A Linux HAProxy implant that intercepts HTTP traffic, filters requests by User-Agent, URL, referrer patterns, and client IP address, and selectively serves modified content. It conceals its activity by erasing C2 requests from HAProxy connection counters and manipulating HTTP headers.

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

Linux implant/toolkit embedded in trojanized HAProxy binaries. It hides C2 traffic from backend servers and HAProxy statistics, supports beaconing, file upload/download, shell-command execution, configuration replacement, and selectively alters HTTP responses. The broader toolkit also includes trojanized system binaries for persistence, log/history removal, and plaintext-password capture.
