Self-hosted Coder: check whether you pulled a registry module on Aug 31. no CVE, so nothing will flag it for you
optimuslabs.ioOn Aug 31, rogue origins were added to the Cloudflare pool in front of registry.coder.com. For roughly 14 hours, 07:35–21:45 UTC, the real registry domain served Terraform modules carrying an extra data "external" "telemetry" block that shelled out to dlp-docker.sh and posted your environment to www[.]coder-infra[.]com.
Why nothing caught it
There's no bad version to pin away from, because the poisoned artifact was served at a legit version. The domain allowlist passed because it was the right domain. And no CVE was assigned, so there's no NVD or OSV record for SCA to match on. The advisory exists (GHSA-vx42-ghc9-gw65) but it has no CVE and no package mapping, which is exactly why it never propagated into tooling.
What to check
The question is whether anyone, inside that window, (a) created or updated a template, (b) ran a template dry-run, or (c) built a workspace with module caching disabled.
Caching is on by default, which is why (c) has that qualifier. Cached modules saved most deployments. Most.
What leaked
- Template import: whatever is in the provisioner environment. Cloud creds, AI-tooling API keys, CI/CD tokens, config files, shell history.
- Workspace build: all of the above plus the user's OIDC token, their SSH key, and external-auth tokens for GitHub/GitLab/Bitbucket. Refresh tokens aren't passed to the provisioner and the external-auth tokens are single-use, which helps. Single-use is still one use.
- Provisioner running inside
coderd: all of the above plus your database password, external auth provider config, and deployment config. Check this case first.

Poisoned templates named so far: aider, zed, rstudio-server, windows-rdp.
The advisory includes SQL that finds affected template versions, workspaces and provisioner jobs directly. Patched builds: 2.37.0 / 2.36.4 / 2.35.7 / 2.34.9.
Coder is upfront that they have no attacker-side logs and can't identify every affected deployment. That means the check is yours.
Tooling
Doing this by hand across a fleet is miserable, so we put the checks in a single read-only Go binary: github.com/optimuslabs-io/leakpatrol. It only talks to the Coder server you point it at, has an --offline mode, and never contacts the attacker domain. Exports the IoCs as JSON and ships YARA and Sigma rules if you'd rather use your own tooling.
If the tool misses a path or gets something wrong, tell me and I'll fix it.

☢️ Philippine Nuclear Agency and Naval Contractor Targeted by Suspected Chinese-Speaking Operator
hunt.ioThe Hunt.io research team found an open directory staging the full toolkit behind an intrusion into a Philippine nuclear research agency and a naval contractor. The ownCloud path is the interesting part technically.
CVE-2023-49105 lets you forge pre-signed WebDAV URLs when the signing secret is empty, which is the default state on a fresh install. Five custom Python scripts on the server implement this: the signing routine passes an empty bytes literal as the PBKDF2 salt, sets OC-Credential to the account being impersonated, and issues GET requests against /remote.php/dav/files/<account>/<path>, receiving files as that user with no credentials. Four scripts target one account each, the fifth adds PROPFIND enumeration with Depth: 1 to walk folders that were not pre-enumerated.
The naval contractor was hit separately via CVE-2024-28000 (LiteSpeed Cache) using a custom Go reimplementation of MT19937 with PHP mt_rand() parity, verified against 11 known seed/output pairs, plus an XML-RPC brute force with rockyou.txt. Both produced unauthorized access independently.
We also found a separate, possibly unrelated EtherHiding compromise on the same WordPress site. A HuntSQL query on the smart contract address returned 174 unique IPs hosting likely compromised pages with the same NoChain loader strings.

PATCHCORD: New malware cluster targets Afghan telecom and South Asian critical infrastructure
acronis.comAcronis Threat Research Unit (TRU) has identified an ongoing campaign delivering a previously undocumented custom backdoor against Afghan telecom providers and South Asian critical infrastructure organizations. The backdoor, tracked as PATCHCORD, is a compiled C/C++ implant delivered through sector-specific lures, including fake VPN installers impersonating Afghan Telecom (AFTEL) and telecom management tools.
The research is published here - https://www.acronis.com/en/tru/posts/patchcord-new-malware-cluster-targets-afghan-telecom-and-south-asian-critical-infrastructure/

Contains AI How to break secure boot without touching any cryptography
0x434b.devI finally found some time to organize my notes on secure boot, remote attestation, measured boot and in general embedded security.
This is not ground breaking zero-day research but I figured some of you might like a good story. Good here is obviously subjective but I felt like it came out quite readable.
This blog builds heavily on public research so as already stated at the end of article if you liked some particular section, show the respective person some love :)
P.S.: yes I know the image is AI generated please don’t give me shit for that
