The downloadable format of CVE&#;x26;#;39;s from Miter will be changing in June 2024, so if you are using CVE downloads to populate your scanner, SIEM or to feed a SOC process, now would be a good time to look at that. If you are a vendor and use these downloads to populate your own feeds or product database, if you&#;x26;#;39;re not using the new format already you might be behind the eight ball!

Billions of PDF files are exchanged daily and many people trust them because they think the file is “read-only” and contains just “a bunch of data”.

A PDF file can also be pretty “dynamic” and embed JavaScript scripts, auto-open action to trigger the execution of a script (for example PowerShell on Windows, etc), or any other type of embedded data.

Package updates/upgrades by maintainers on the Linux platforms are always appreciated, as these updates are intended to offer new features/bug fixes.

Consistently backing up your data before significant updates is one good countermeasure against grief.

I was recently put in this unenviable position when configuring one of my systems, and somehow, the latest version of Proton VPN (version 4.3.0) would not work and displayed the following output after I executed it:
