Tracing acme.sh certificate handling in TLS interception

I spent too long chasing the neat version of TLS wiretapping reconstruction, then found the mess: shell parsing, token limits, and renewal timing. The interesting bit is not the packet capture, it is the point where certificate handling quietly hands trust to something you did not mean to trust.

Reverse engineering game binaries with static analysis

Game binaries give up more than they should, if you know where to look. I start with binary analysis, not the folklore around the game, then use...

Agentic AI still needs domain judgement

Agentic AI can write the thing, but it still cannot tell you whether the thing is right. That is where domain expertise matters, because a clean...

Android security boundary failures around AuthToken handling

Android Biometric AuthToken handling is one of those details that looks tidy until you trace what actually trusts it. I pay closest attention to the hand-off points, because that is where a neat...

Access control in WrappedADS authorised mint flow

WrappedADS wrapTo() mint path is not hiding much, and that is the point. If the caller is trusted, the mint goes through; if that trust is wrong, supply moves just as easily.

redeemPosition rounding turns fixed deposits noisy

A fixed deposit should not unlock more SEA just because the round counter shifts. The SEA settlement adapter let that line blur, and a flash-loan loop made the mistake expensive; once redemption...

MMR proof indexing in a bridge dispatcher audit

The ugly part of an Ethereum bridge dispatcher is not the proof itself, it is the gap between a tidy verification trace and the bytes that finally reach custody logic. If those two ever diverge, the...

Uniswap V2 spot reads distort reward payouts

A pair reserve is a terrible price feed when someone can shove it around for one transaction. I have seen the same bad read turn cheap stake entry into inflated principal, then pay out rewards from...

Web shell persistence in BadIIS loaders

BadIIS is not clever, just persistent, and that is what makes it unpleasant. It survives IIS restarts, rewrites selected traffic, and leaves behind enough build artefacts, like demo.pdb, to give...

OpenVPN vulnerabilities and patch priority

OpenVPN vulnerabilities are easy to shrug off until they hit the client, where malformed packets can knock out remote access before the tunnel is even trusted. I would patch that before almost...

Operational threat intelligence for IIS hijacking

IIS hijacking is boring until it is not, which is exactly why a threat intelligence programme has to watch for the awkward bits, not the headline alert. When redirects, 503 spikes, and odd proxying...

GitHub source code exposure via third-party tooling

GitHub source code exposure rarely starts with the platform itself, it starts with something trusted too much. I care less about the headline breach than the awkward bit underneath, where a...

Data exfiltration signs from signed Setup.exe flows

Signed `Setup.exe` did not fool me for long, because the runtime behaviour was wrong from the start. The interesting bit in cloud environment exfiltration is usually the small `.config` file beside it...
