dear iOS developers . Please pay someone to do pen testing of your apps. Or at the least - open up the IPA file (the zipped up bundle) and have a look at what you're shipping in the bundle.
Like, for instance if there's a private key in there - perhaps rethink your life choices.

kthx

Sending disclosures to people is the opposite level of excitement to when you discover them .
Anxiety and depression ensues .
Or is that just me ?

Imagine exposing all your docker containers in live system for anyone to pull.
I just had to report that to a real business with 10+ history.

Oops

Love it when licensing verification code has 3 different implementations of simple calendar look up. But they use rand()%N to sometimes skip some of them .
I got so many pieces of advice for the person who think it’s clever (it’s not).
Use the @ when contacting me ;-)

Introducing BullCrap: New programming language - just for AI. You won't understand it, so I won't publish the spec. It's just for AI , by AI. I didn't even write it. I was told to talk about it tho. Soon to be powering Android phones and Windows shitboxes near you.

#moderndayslavery He Leaked the Secrets of a Southeast Asian Scam Compound. Then He Had To Get Out Alive.

A journalist received an encrypted email from a source claiming to be a computer engineer working inside a major crypto romance scam operation in the Golden Triangle.

A Must read .

You’d think Apple would be interested in handing folks decrypted IPA’s of iOS apps
. Especially free ones .
