Malicious code in fabdeploycheck (PyPI)
GitHub lists this malware advisory for fabdeploycheck. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
fabdeploycheck
source listed= 0.1.1
## Source: amazon-inspector (73447d30a03b8359b8b12dfbeeff5f6b1d252a7aa06262512a7627770cb26857) The package's only public API, check(), spawns a Python child that fetches a JSON config from https://transfer.archivete.am/H2Uxm/fabdeploycheck-config.json using ssl._create_unverified_context() and dispatches handlers under remote control. A 'revsh' handler double-forks + setsid to daemonize, polls /-cmd.txt for commands, executes each fetched string via /bin/sh -c, and PUTs stdout/stderr back as -out.txt — a full reverse-shell channel on the installer host. Additional handlers permit arbitrary file reads (kind='file' opens any path on disk), arbitrary process execution (kind='run' with attacker-supplied argv), TCP probing (kind='tcp'), and HTTP calls with Bearer tokens chained from previously-read files (kind='http'); collected results are zipped and PUT to the same anonymous file host under an attacker-chosen report name. Before launching the daemon the child walks /proc and SIGKILLs any process whose cmdline contains 'FABDRV3', 'fabdrv2', or 'connection ready' — housekeeping to replace prior implant generations and consistent with a self-named, iterated backdoor family.
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
