wait… Amazon isn’t testing nor reviewing AI generated code?! 😆😆😆

[Anish Moonka @anishmoonka]

Amazon had four Sev-1 outages (their highest severity level) in a single week. Internal memos say AI-assisted code changes were a contributing factor.

The timeline here is wild. In October 2025, Amazon laid off 14,000 corporate employees. In January 2026, another 16,000. That’s about 30,000 people in five months, roughly 10% of the corporate workforce. CEO Andy Jassy said the cuts were about culture, not AI.

During those same months, Amazon set a target: 80% of developers using AI coding tools at least once a week. They tracked adoption closely and blocked rival tools like OpenAI’s Codex. Even so, 30% of developers still hadn’t touched Amazon’s in-house tool Kiro by January.

In December 2025, Kiro caused a 13-hour AWS outage. The AI tool had production-level permissions and decided the best fix for a bug was to delete and recreate an entire live environment. A second incident involved Amazon Q Developer, another AI tool. Amazon blamed both on “user error, not AI.” But quietly added mandatory peer review for all production access afterward.

Then March 5: Amazon’s retail site went down for about six hours. Over 22,000 users reported checkout failures, missing prices, and app crashes. Amazon called it a “software code deployment” error.

Five days later, SVP Dave Treadwell made the normally optional weekly engineering meeting mandatory. His memo acknowledged “GenAI tools supplementing or accelerating production change instructions, leading to unsafe practices.” These problems trace back to Q3 2025. Amazon’s own assessment: their GenAI safeguards “are not yet fully established.”

The new rule: junior and mid-level engineers now need senior sign-off on any AI-assisted production changes. Treadwell also announced “controlled friction” for the most critical parts of the retail experience.

For context, Google’s 2025 DORA report found 90% of developers use AI for coding but only 24% trust it “a lot.” An Uplevel study of 800 developers found Copilot users introduced 41% more bugs with no improvement in output. Amazon is finding out what those numbers look like at the scale of a $500 Billion revenue company, with 30,000 fewer people on staff to catch the mistakes.

@sirada_l just got a message from the fake one

[Alex Donn @Alex_Donn]

@0x_eunice see you there!

[OtterSec @osec_io]

We found the same Fiat-Shamir bug in six independent zkVMs.

The result: an attacker can bypass the cryptography entirely and prove mathematically impossible statements (like minting $1M out of thin air).

[Jay @jayendra_jog]

This novel approach to sharding transaction data is only available to chains using MCP for consensus, which is why we teamed up with researchers @LefKok and @alberto_sonnino

Our community CTF is now live at @SolanaConf 🔥

Come by the Dev Cave on the mezzanine level, hosted by OtterSec, @anza_xyz, @asymmetric_re, @jump_firedancer, and @raikucom. ​

Drop by to work, meet other builders, and grab some swag.

[OtterSec @osec_io]

We have just completed our thorough audit of @jup_lend, and we are happy with @JupiterExchange and @0xFluid’s attention to detail and security!

[OtterSec @osec_io]

NEW: OAuth misconfigurations show how common dev settings can lead to account takeovers.

Our second deep dive breaks down real cases where overlooking differences between desktop and mobile environments left SDKs, exchanges, and wallets open to exploits.
