@redhat-cloud-services publish pipeline is compromised today and shipped a signed, trusted, malicious npm package
https://www.reddit.com/r/programming/comments/1ttt4p4/redhatcloudservices_publish_pipeline_is/
<!-- SC_OFF -->patch-client@4.0.4 (mailto:patch-client@4.0.4) went out through the project's own github action OIDC trusted publisher today and not any stolen token or a typosquat anything, we saw that the actual release pipeline produced it. this runs on npm install, steals cloud creds and self propagates by injecting fake CodeQL workflows into repository the stolen tokens can reach. 32 packages is currently sharing the same publisher so the window of exposure isn not only just a single package.
if you have anything from related to /redhat-cloud-services in your tree, 4.0.3 is the last clean version. <!-- SC_ON --> submitted by /u/BattleRemote3157 (https://www.reddit.com/user/BattleRemote3157)

The case for Direct I/O - why it matters for high performance storage

Internally, it uses Direct I/O (O_DIRECT) almost everywhere. In this article I explain the reasons behind this choice, also motivated from some fun experiments I had with fio that you can find in the article. and some consideration about the page cache. <!-- SC_ON --> submitted by /u/IlPresidente995 (https://www.reddit.com/user/IlPresidente995)

Someone hid a full RAT inside a fake npm package and exfiltrated victim data to HuggingFace
https://www.reddit.com/r/programming/comments/1tqwksq/someone_hid_a_full_rat_inside_a_fake_npm_package/
<!-- SC_OFF -->A malicious npm package name js-logger-pack, went through 29 versions on the registry which was looking innocuous logger and ending as a binary dropper.
The payload it dropped was 81 MB of binary called MicrosoftSystem64 which is a full cross-platform RAT packaged as a Node.js Single Executable Application, so it shows up as a native binary to endpoint tools rather than a node process. And the clever bit was instead of sending the stolen data directly to a C2 server, it uploads everything to private HuggingFace datasets using an embedded API token. So all exfiltration traffic appears as normal HTTPS requests to a legitimate ML platform.
If you have any of those in your install history then rotate everything like credentials, SSH keys, API tokens, crypto seed phrases. All packages list and full technical breakdown is in blog. <!-- SC_ON --> submitted by /u/BattleRemote3157 (https://www.reddit.com/user/BattleRemote3157)
