Software went from desktop-first to mobile-first, now going to agent-first.

1/ We are sharing additional details regarding our investigation into unauthorized access to GitHub's internal repositories.

Yesterday we detected and contained a compromise of an employee device involving a poisoned VS Code extension. We removed the malicious extension version, isolated the endpoint, and began incident response immediately.

@gregpr07 Nah man, Codex just wayyyy better now. I literally stopped using Claude Code as the app now sucks

[Dhia Louhichi @dhayhak]

Have been using Opus 4.7 since launch and I can say for sure I prefer 4.6. 4.7 just feel dump. I need to do more followups and it assumes things waaaaay often, wrongly..

[Dhia Louhichi @dhayhak]

This is for my product https://t.co/O31ucVYnFg btw

[Dhia Louhichi @dhayhak]

There is nothing better than a happy customer 🙏

@theo Lmao

[Dhia Louhichi @dhayhak]

Multiple customers asked for this already and I'm so happy to launch it!

Something cool is cooking!

[Dhia Louhichi @dhayhak]

This week I had to block a @getzenophone user because he abused the system to make calls using IRSF.

What’s IRSF? It’s International Revenue Sharing Fraud, a well-known fraud in telecom where someone exploits a phone app to call international premium numbers and share revenue with a carrier.

They managed to get around $20 from zenophone.

On https://t.co/T5yibCrjFT, there’s a Caller ID feature that lets you show your own number when making a call. To activate it, the app calls your number and you enter a code.

The issue: the app could call any number for that verification step.

The fraudster leverage this feature to make outbound calls to these premium rate numbers for free.
Fortunately I had a top-up limit with my telco provider, which triggered a notification. Otherwise this could’ve cost much more.

The fix was simple:
- Caller ID now costs 1$: cheap for regular users, but expensive enough to discourage abuse
- Blocking high-risk / premium numbers
- More aggressive rate limits

I knew about IRSF when building @getzenophone but missed this specific abuse vector. Glad the impact stayed small.

I’ll try to share more learnings building zenophone.

@OpenAI codex team have been cooking! I've been using it exclusively recently and lovin it.

[Dhia Louhichi @dhayhak]

Anthropic should pause all features dev at this point and focus on reliability for the next 2 week, similar to what Cursor did end of last year. I don’t care about a review feature if the core product had been so bad this week.

[Peter Yang @petergyang]

This happens like 2x a week now. I have to use ChatGPT more because Claude can't stay up.

@getzenophone Check it out here https://t.co/O31ucVYnFg

[Dhia Louhichi @dhayhak]

The importance of reaching out to every customer.

A customer replied to my check-in email about @getzenophone. They shared a bug in the auto-topup feature that charged them twice. They also said the email didn't work🤦‍♂️ So double failure from my part! I've apologized ofc, reimbursed them and fixed the bug.

[Dhia Louhichi @dhayhak]

Really? Just saw this 🤦‍♂️
