I'm super proud of myself. One step closer to quitting my job and becoming a full-time auditor. Thank you to @cantinaxyz for the opportunity.

@AndrewMohawk First time hearing about the H1b visa thing - can you opt to donate the bounty to charity?

@0xabi96 @immunefi I can't believe it has taken this long! Do you have access to read the full original report?

Seems a bit more relevant now🤷‍♂️

Marking privileged roles as OOS seems so dumb to me 99% of the time. I'm here because I don't want to trust anyone but code. If an admin can fuck up your protocol (but we can fix it be adding safeguards), then why wouldn't we? Verify, don't trust.

This is what @PatrickAlphaC does to people who store their private keys in .env

Before Ethereum even launched, a security researcher found a bug that let you send yourself unlimited ETH

All you had to do was send a negative payment

The code removed the amount you sent from your wallet but if the amount was negative, your holdings went up instead of down

Ethereum's own release coordinator called it "my favorite bug so far, an absolute gem: the ability to send a negative payment that moves value FROM the recipient TO the sender"

The bounty for finding it was 5 BTC and the exploit code is still live on GitHub right now

A $230 billion network almost launched with an infinite money glitch built into it

[f4lc0n @al_f4lc0n]

the figures referenced in the post are entirely misleading. There was no impact realized from this issue. Zero user funds were affected and zero addresses were compromised.

My response: Are you suggesting I should have actually exploited the bug and caused real damage before coming to talk to you?

For the stated vulnerability to work in practice, it would require execution of several suspicious transactions that would have an extraordinarily limited impact.

My response: You should know better than anyone that on a Cosmos-based chain, a single transaction can pack multiple messages. Just one transaction is more than enough to completely drain multiple whale accounts.

Injective has dynamic rate limiting functionalities which are applied automatically based on our live monitoring systems. This functionality has been live on mainnet since last year and is publicly available in our code base.

My response: First, this has nothing to do with the vulnerability itself. Rate limiting doesn't stop attackers from stealing funds. It only slows them down when they try to bridge those funds over to Ethereum. Second, when I submitted my report, the mainnet configuration for this feature was not set. In other words, this feature wasn't even turned on!

In addition to all of the above, this report was reviewed against the clearly defined terms of our Immunefi program. Based on those terms, issues such as those raised in this report that DO NOT impact block production or consensus are categorized outside of the Blockchain/DLT tier and carry a maximum payout of $50,000.

My response: First, Immunefi has always put the impact of direct fund theft at the very top of its priority list. This is a fact that everyone knows. Second, you changed your bug bounty page after I submitted my report. Here’s the snapshot from November 8, 2025: https://t.co/ykKckJVrVM . And now, there’s an extra line added to your bug bounty page: “IMPORTANT: Within the Assets in Scope table, the injective-core folder is listed for both Blockchain/DLT and Web/App due to overlap between the two within the same folder. However, for a report to be categorized as Blockchain/DLT, the resulting impact has to be directly involved with the block production process or with consensus failures. All reports not dealing directly with either of these are to be categorized as Web/App.” I’d really like to know when this line was added. and do you really value chain consensus more than users' funds?

We remain committed to fair, transparent, and consistent handling of all reports, and to maintaining the highest standards of security for the ecosystem. Injective has done so since its mainnet inception in 2021 and will continue to do so in perpetuity, always putting builders and security first.

My response: You never even replied to my messages, and now you’re blaming me for not requesting mediation? I can post the original report if you agree. I left many messages, but you haven't replied to a single one.

----------

Finally: Stop making excuses from every angle and trying to use technical jargon to confuse people who aren't developers. That doesn’t work anymore these days. Anyone can just ask an AI to fact-check what both of us are saying. I have no ill intentions toward your project. All I'm asking is for you to be honest and handle this transparently.

[Immunefi @immunefi]

Security researcher ily2 has just earned a staggering $3,000,000 from submitting a critical smart contract bug via Immunefi.

That's the largest single payout in web3 security in recent memory.

In total, he's submitted 3 reports. All 3 were paid. 100% accuracy.

His leaderboard update is coming soon, but you can pledge IMU to him now and earn when he finds the next one:

@legendydx Earning less than $10 in a contest is a rite of passage.

@denicmarko Amazing! Cryptozombies is a tiny bit outdated now though, I'd recommend replacing it with @CyfrinUpdraft
