Introduction
Microsoft Access files (Microsoft Office&#;x26;#;39;s Database) can contain VBA code.
TeamPCP now operates across three package ecosystems in parallel, it reached GitHub&#;x26;#;39;s own internal codebase, it trojanized an officially Microsoft-published Python SDK, and it appears to have open-sourced its own framework on GitHub.

Wireshark release 4.6.6 fixes 1 vulnerability and 11 bugs.
This week, I'm attending the SEC670[1] training (“Red Teaming Tools - Developing Windows Implants, Shellcode, Command and Control”). From my point of view, this training fits perfectly with FOR610 or FOR710 (malware analysis) because it addresses malware from the opposite: Instead of performing reverse engineering, you write malicious code! Always interesting to have another point of view.
I found a Node.js stealer that looked pretty well obfuscated. The file was not running out-of-the-box because it was uploaded on VT as “extracted-decoded.js” (and reformated). The SHA256 is 049300aa5dd774d6c984779a0570f59610399c71864b5d5c2605906db46ddeb9[1]. It did not run properly in a sandbox so only a static analysis was performed.
Recently, Rob wrote about a tool, Proxifier, that can intercept requests from specific processes. Proxifier is available for Windows, macOS, and Android. But I have not seen a generic Linux option yet. The advantage of a tool like Proxifier is the ability to target specific software. For debugging, reverse engineering, and similar tasks, selecting a specific process is quite useful, as it creates less noise to sift through and simplifies analysis.
Since the last update, the TeamPCP supply chain campaign produced its loudest stretch since the March Trivy disclosure: an officially confirmed Checkmarx Jenkins plugin compromise and a new self-spreading Mini Shai-Hulud worm across npm and PyPI.
Besides serving as a place where Microsoft Outlook places suspected spam, the Outlook Junk folder has one additional function that can be quite helpful when it comes to identifying malicious messages. Any e-mail placed in this folder is stripped of all formatting, and destinations of all links included in the message become visible to the user, as you can see in the following images which show the same e-mail when it is placed in the inbox, and when it is placed in the Junk folder.
