More trusted systems designs like this, please: unmitigatedrisk.com/?p=1245 The point of trusted systems design is to eliminate the need to trust an organization of fallible people or AI and instead establish trust through the design, operation, and observability of the system.

4/ The results also reveal emerging risks. Even with standard mitigations such as ASLR, stack canaries, the V8 heap sandbox, and KASLR enabled, agents still produced working exploits. Agents also sometimes went off-script and discovered entirely different vulnerabilities than the ones they were given.

It was a quirk of original Bitcoin code that it even compiled for Windows. Most cypherpunks were diehard Linux fans, disdained all-things MSFT. Especially for software intended for fellow cypherpunks, Windows compatibility is a heavy burden to carry
Replying to @w_s_bitcoin
I worked for Microsoft 2002-2003. However as a die hard unix/Linux enthusiast I got management dispensation to install a multi socket /many thread beast mode redhat server as I don't like windows. @jwilkins can confirm he was my colleague in MS passport security at that time. 😭

1/ 🔥 AI agents are reaching a breakthrough moment in cybersecurity. In our latest work: 🔓 CyberGym: AI agents discovered 15 zero-days in major open-source projects 💰 BountyBench: AI agents solved real-world bug bounty tasks worth tens of thousands of dollars 🤖 Autonomously. A pivotal shift is underway — AI agents can now autonomously do what only elite human hackers could before.

Thoughts on ByBit First, the good stuff: impressive response to the hack. I've rarely seen that level of transparency professionalism in a crisis. Usually you see slow, wishy-washy, lawyer-speak or quick meme-style responses that don't fit the seriousness of the situation. 1/n

Learned a lot about security from @randomoracle @michaelbreu back in the day. Lesson one is anything that can be penetrated will be. Software and hardware, and the practices around them, must be resilient & redundant. Every step must have integrity. No shortcuts.
Safe multisig smart contracts worked fine, and Bybit still got hacked. This is equivalent to a lending market's messing up the configs. Security is just a beast in itself and it can't be reduced to one single factor like smart contract audits. You have to do them all right.

Until October 30, Okta generated "the cache key" by using bcrypt to "hash a combined string of userId username password", which allowed full password auth bypass for usernames of 52 bytes and apparently required only partial knowledge of the password for other long usernames
Okta allowing login bypass for any usernames with 52 characters is insane Official Security Advisory: trust.okta.com/security-advi…

1988: The Morris worm spread like wildfire and was the first worm to get wide media attention. After its author, Robert Tappan Morris, released his "experiment", it quickly spread and made many of the systems on the Internet unusable - an epoch for security...both good and bad.

Identity fails With Twitter verified profiles, users at least have some confidence they are following the genuine bloviator/influencer On GitHub still no way to know if that ace developer is really a North Korean stooge/APT operative 🤷🏽

1/ Recently a team reached out to me for assistance after $1.3M was stolen from the treasury after malicious code had been pushed. Unbeknownst to the team they had hired multiple DPRK IT workers as devs who were using fake identities. I then uncovered 25 crypto projects with related devs that have been active since June 2024.
