Pre-boot authentication for BitLocker

TPM-only BitLocker is convenient, but convenience is not the same as a proper boundary. BitLocker PINs push that line back to pre-boot, which is where I want it if the machine might be stolen, tampered with, or left somewhere I do not trust.

Single-sided BPool joins drain mOCEAN via SideStaking

Ocean Protocol BPool single-sided join exit math is where this one falls apart, and I have a soft spot for bugs that look tidy until another contract...

ecrecover checks for Lixir Vault permit signatures

Chaining logic bugs in Microsoft Edge sandbox escape

Microsoft Edge sandbox escape chains do not need memory corruption if the trust checks are loose enough. Orange Tsai’s Pwn2Own chain was nasty...

LiteLLM exploit chains at the auth boundary

LiteLLM exploit chains only work because the auth boundary is doing too much, and failing badly when the database wobbles. I trust a proxy less when a bad lookup can quietly turn into proxy-admin...

Manual validation in AI-assisted pentesting

Corecrypto proofs against FIPS 203 and FIPS 204

Apple’s corecrypto formal verification work is interesting because it is properly dull, in the best sense. It ties a portable C implementation back to FIPS 203 and FIPS 204, then leaves the optimised...

alloc_pipe_info: why soft limits shrink new pipes

When pipe-user-pages-soft bites, the kernel stops being predictable in the way people like to assume. I prefer to check F_GETPIPE_SZ and watch the slab class shift for myself, because the difference...

Detecting hosting infrastructure abuse in transit

A clean brand can hide a dirty transport chain, and that is where hosting infrastructure abuse detection starts to matter. I care less about the logo than the packets, because if the upstream changes...

Proxmox VE 9.2 VM migration after storage changes

Proxmox VE 9.2 VM migration gets awkward the moment storage changes underneath it. I have seen a VM boot happily on one node, then fall over on the next because the disk still points at the old...

Coordinating upgrades in Proxmox Datacenter Manager 1.1

Proxmox Datacenter Manager 1.1 only behaves if you keep the control plane ahead of the mess underneath. I prefer to upgrade the manager first, then watch the inventory like a hawk, because stale state...

Sitecore cache poisoning coverage after WAF merge

Cloudflare WAF rule merging is exactly the sort of tidy-looking change that can muddle your monitoring. I have seen a live block disappear from a dashboard simply because the rule name moved, which is...

Managed ruleset tuning after Cloudflare rule changes

Cloudflare WAF managed rules do change under you, and the tidy-looking rule in the dashboard is not always the one doing the blocking. I have learned to trust Security Events first, then tune, because...
