🎉🎉🎉 Hotel and flights are covered!!! 🎉🎉🎉 - If you've got an idea for a talk, we'd love to see you at BlueHat!
Call for papers closes on December 8th: https://msrc-blog.microsoft.com/2022/10/13/bluehat-2023-call-for-papers-is-now-open/.
#TryHackMe is hosting an Advent of Cyber. Beginner friendly exercises AND prizes so anyone of any skill level can participate.
If coding is more your thing, @singe posted about #AdventOfCode which has small coding tasks each day
Hope to see a lot of progress from everyone. Maybe we can treat this like Wordle and share progress to keep everyone engaged?
Keynotes and briefings from BlackHat 2022 are now online (h/t @eng) https://www.youtube.com/user/BlackHatOfficialYT
Certificate authorities (CAs) are a critical backbone of internet security; when they are compromised, users lose the ability to securely connect to websites without fear of interception. Websites cannot insulate themselves against a fully-compromised CA, even if they normally use other CAs.
I wanted to add a rand() biased default value to a column in #MySQL. To support replication, that is not allowed, so you must use a trigger. You cannot use the trigger to update the inflight INSERTed rows unless you set the trigger to occur BEFORE insert:
Example:
DELIMITER $$
CREATE trigger set_rand BEFORE INSERT on `tbl` FOR EACH ROW
BEGIN
IF NEW.randcol IS NULL THEN set NEW.randcol = FLOOR(RAND()*999999999);
END IF;
END$$
DELIMTER ;
Hidden gem in the paper just shared by @vanhoefm https://dl.acm.org/doi/abs/10.1145/3495243.3560530
A single frame can wake up (from power saving) all devices on a network and get them to respond with their real, not randomized MAC address. A beacon management frame with the Traffic Indication Bitmap (TIM) set to FF for all devices.
An AArch64 fuzzer based on the Apple Silicon hypervisor. Looks like an interesting project and the docs are well written.
