  • A lot of healthcare facilities are running EOL operating systems like Windows XP or Windows 7 because the programs they use for billing or other reasons are stuck on that version. You would be shocked at how prominent this is across most “modern” infrastructure. The resistance to change stems from a “if it isn’t broken, don’t fix it” mentality. Pagers are still the most reliable ways to reach a doctor, which is why they’re still used, not because they’re necessarily the most secure.

    As easy as it is to point blame at “duh boomers” the situation with healthcare in particular is much more nuanced. Though I do agree that any luddites in charge of major hospitals are not helping the situation at all.









  • In a nutshell, a backdoor was intentionally planted by a malicious actor in xz Utils, an open-source data compression utility widely used in Linux and other Unix-like operating systems. This discovery was made by Andres Freund, a developer and engineer working on Microsoft’s PostgreSQL offerings. He was troubleshooting performance problems on a Debian system. Specifically, SSH logins were consuming excessive CPU cycles and generating errors with Valgrind, a memory debugging tool. Through sheer luck and Freund’s careful eye, he eventually discovered that these issues were the result of updates made to xz Utils. Upon closer inspection, he found that updates to xz Utils were the result of a maliciously inserted backdoor. The backdoor, present in xz Utils versions 5.6.0 and 5.6.1, manipulated the sshd executable, allowing anyone with a predetermined encryption key to upload and execute arbitrary code on affected devices.
