TIL that with a linker script, you can have emojis as ELF section names.

I need an opportunity to use this knowledge.

Picard management tip: Take your leisure time seriously. A relaxed captain is a sane captain.

Here's a no-cost, non-denominational, last-minute gift idea.

Reach out to people who made a positive difference in your life but with whom you have not been in touch for a while. Tell them that they were a force for good in your life. Thank them.

Be generous -- pass on this idea. Spread some joy.

One the twelfth day of Christmas, the true goat gave to thee: https://infosec.press/screaminggoat/patch-tuesday , which is a list of vendors' security advisory landing pages and their #PatchTuesday schedule.

Disclaimer: Not every vendor is listed, and their patching cycle may be different than what I categorized them as, but it's a good starting point. Ideally, you'd be tracking the ones you care about using RSS anyway.

Merry Christmas Infosec Mastodon

OK, this is my summary for today

#Rust

Hewlett Packard report that they are spotting AI-generated malware in the wild, not through complex analysis or watermarking, but because… it is weirdly well-commented. https://threatresearch.ext.hp.com/wp-content/uploads/2024/09/HP_Wolf_Security_Threat_Insights_Report_September_2024.pdf

I'm at about third of the 100 #Rust exercises and I think we just got to the "Draw the rest of the fucking owl" part 🖊

I find CVE-2024-40896 (Raptor/libxml2 XXE) very educational:

Based on the analysis[1] it's a nice example of Chesterton’s Fence[2], while its discovery[3] underlines the importance of automated testing for regressions and known dangerous behavior.

More than funds, what Wikipedia really needs is more good editors. The number of people who regularly edit articles in English Wikipedia hasn't grown substantially in years, while the number of articles has, and editor demographics remains skewed. The foundation itself largely stays away from editing, leaving it to volunteers. While articles that get a lot of attention are often good, it's not hard to find ones with biased and promotional content in less-visited topics, and in other languages.
