@leeb The IBM 1401 computer had optional support for math with pounds/shillings/pence in hardware, back when there were 12 pence in a shilling and 20 shillings in a pound. Of course there were two incompatible standards, so the computer had a knob on the front panel to select the standard.

Today is the 10 year anniversary of the first time I ever pwned anything!

My first exploit was a simple stack smash, overwrite return ptr, jump to admin function. This was an in internal recruiting CTF by @gaasedelen for the RPISEC

Before that day I had never even considered computer security and was primarily doing robotics.

You never know when a buffer overflow may change the very course of your life!

"Listing all processes keeping particular file open is not a trivial task but since Vista we have a special syscall parameter for such purpose. Microsoft says "reserved for system use" but I was brave enough to wrap it into PowerShell function. Enjoy!" @0gtweet

Next-Level Reversing: Binary Ninja+TTD

Years ago, I created a bot that posted Sun Tzu quotes, if Sun Tzu had written about cyber war. When X closed up API access that bot broke, and it never was high on my list of priorities to bring here. Well, I just fixed that. May I introduce you to @SunTzuCyber, which posts every 6 hours. The posts are set up as unlisted/quiet public, so they won't show up in timelines unless you follow it.

There's a large number of #FreeBSD, #OpenBSD, and #illumos users out there.

We don't talk much because it "Just Works™"

I was not able to prove this for a very long time, so I used the most powerful weapon available out there: asking!

Did you ever found firmwares for Tricore or v850 architectures accessing addresses starting with 0xa.. instead of the 0x80.. one? after so much research I end up learning that this is handled by the mmu which applies a cache layer on top of the same memory range. In other words: IDA lies by fake the references by dropping the 3rd bit, ghidra can't handle this, and r2 is again the only tool able to properly define this memory layout.

I may be late to the party but today I’ve learned that ASML has installed a kill switch into an extreme ultraviolet lithography machine it has sold to TSMC, allowing it to be shut down if China invades Taiwan.

North Korean threat actor Citrine Sleet exploiting Chromium zero-day

https://www.microsoft.com/en-us/security/blog/2024/08/30/north-korean-threat-actor-citrine-sleet-exploiting-chromium-zero-day/?s=09

GitHub copilot seems to be high.

I typed "A simple hash function.", then autocomplete kicked in.

This is absolutely nuts. SQL Injection 101 attack on a site authorized by DHS for TSA vetting of known crew members. I’d bet there aren’t even audit logs that would be able to show if the system was tampered with.

How many other auxiliary sites with deep ties into critical infrastructure are this poorly secured?

"Just don't give a damn about what anybody else thinks of you!"

Well that is all nice and dandy, unless the 'anybody else' has the power and means to actively make your life harder.

Because at that point, you realize that not caring what anyone thinks is a privilege.

At the height of One Million Checkboxes's popularity I thought I'd been hacked. A few hours later I was tearing up, extraordinarily proud of some brilliant teens.

Here's my favorite story from running OMCB :)

In light of the issue page for CVE-2024-5274 being made public. Me and @buptsb
have decided to make our exploit public. It's a bit different than the issue page POC.

I was happy to be quoted alongside security research leaders like @dustin_childs and @haifeili on the challenges with (good-faith) coordinated vulnerability disclosure. https://www.csoonline.com/article/3491353/is-the-vulnerability-disclosure-process-a-glitch-in-itself-how-cisos-are-being-left-in-the-dark.html
