💥🐹 4 new Go Code Review Labs just dropped! 🐹💥 Read the code, peek at the diff, find the bug. Sharpen your skills: pentesterlab.com/badges/golang-…

@GVilaniya Congrats!!

I just completed @Pentesterlab's Authentication / Authorization Badge!!!

Back in the day I used to do code reviews to actually learn stuff… now I’m just doing them like quick little brain teasers 😄 Big shoutout to @PentesterLab for keeping my puzzle game strong.

I just completed @Pentesterlab's Golang Code Review Badge!!!

I just completed @Pentesterlab's Essential Badge!!!

I spent last week, this week-end and the start of this week working on a redesign of @PentesterLab 's website. Aiming for something a bit more modern... Let me know what you think!

"Users can log in with any password". Some of the best bugs make zero sense until you look into the code! Great writeup.

@AhmedMo15851348 خبرتك في ال web dev هتوفر عليك وقت كبير ال ejpt بداية كويسه لو حابب تسرع الدنيا ممكن تشترك في @PentesterLab لو تقدر هيختصر عليك وقت أكبر

💥 Another 3 new JS code review lab: pentesterlab.com/badges/javascr…

A commit meant to "strengthen the crypto" in FreshRSS ended up removing the need for a correct password. Why? Longer SHA-256 nonce + bcrypt truncation at 72 bytes. A nice example of why secure systems are about composition, not just stronger primitives. pentesterlab.com/blog/freshrss-…

I wrote about what happens when you rewrite mature software with agents. You rebuild the features. You don't rebuild the scars. vinext: one engineer, one week, $1,100 in tokens. Then plenty of vulnerabilities found within days. pentesterlab.com/blog/what-you-…
