34 researchers have now earned $1M+ in bug bounties on @immunefi 4 of them crossed the mark in 2026 alone, and another is $82K away from becoming a millionaire. There’s more than one way to get there. 7 reached seven figures with a single report. Another got there with 106 reports. The best security researchers go where serious money is on the table. When a single critical finding can pay five, six or even seven figures, the people capable of finding those bugs keep showing up and keep looking. That’s the pool of talent a protocol taps into the moment it launches a bug bounty. It keeps researchers looking after launch, through every upgrade and integration, for as long as the program runs. Every payout rewarded a verified vulnerability sent to the protocol team - never an attacker.

In simple terms, @hyperlendx HyperLend is a lending platform where bad actors can profit from predatory liquidations. An automated program can easily make an 8% profit on each liquidation, pushing the annual ROC above 100%. Meanwhile, regular borrowers are constantly on the verge of a 20% capital loss with no justification. This is a scam orchestrated by the HyperLend team. Do not put your money into this fraudulent protocol.

156 submissions with $50 fee in 1 day 😅 the +EV move no longer seems to be finding bugs, but having a bug bounty hosted with a high submission fee 🤣

The project team actually cheated me after I reported a real vulnerability that could drain funds from its vaults. I softly introduced the matter in their Telegram group, and the owner quickly DM'ed me, offering a bounty if it was meaningful. But after reading my PoC, he started making excuses, saying this was already reported by others and fixed in their recent audit. What? Then how does this real bug still exist on the mainnet? In simple words, an attacker can cause a loss of more than 6% to lenders with each attempt and drain significant funds. Yet, the vague reply of the team was that they don't have an issue with it. Then they suddenly deleted all private DMs and banned me from the Telegram group. Moral of the story: day one of a Whitehat becoming a Blackhat.

The bug bounty ecosystem has a serious trust problem. Yesterday, I submitted a report with a clear runnable PoC against an in-scope asset, only for the platform to close it as “out of scope” without proper technical justification. Last week, I responsibly disclosed another vulnerability with a fully reproducible PoC according to the program rules, complete silence from the project team. I also found a critical issue in another protocol without a public bounty program. This time I withheld the sensitive exploit details and contacted them privately first. They acknowledged the email and promised a response. Nothing since then. What’s frustrating is that many teams hesitate to pay a whitehat even a relatively small bounty for responsible disclosure. But when an actual exploit happens, the same teams suddenly offer hackers 10% recovery deals worth millions. If protocols continue ignoring researchers, dismissing valid reports, or hiding behind vague “out of scope” claims, they are incentivizing silence instead of responsible disclosure. In the end, everyone loses: the users, the protocols, and the security researchers trying to help before real attackers do.

Last week, I completed deep security research on two DeFi protocols and identified serious exploitable vulnerabilities including fund drains and other critical risks during my analysis. I provided a full Proof of Concept (PoC) and detailed findings to the project teams via email. Their response? Utter silence. For the first protocol, I am currently holding back the PoC while awaiting an update from the team. However, the report for the second protocol will soon be published right here on my account. Follow me to stay informed, avoid vulnerable protocols, and secure your funds. If I don't hear back, I will publish my findings and tag the projects' X handles within the week.

The developers of these projects are also to blame for such pathetic drains and the permanent shutdown of their protocols. Many recently exploited platforms were reportedly alerted in advance by elite security researchers, but the administrators hesitated to offer meaningful bounties, which ultimately resulted in the loss of all their funds. Recently, an elite hacker discovered a vulnerability, provided a partial proof of concept (PoC), and requested a $25,000 reward along with remediation guidance. Instead of acting quickly, the owners delayed the process and tried to bargain. Consequently, the protocol was drained of more than $10 million, effectively destroying the project. A simple hesitation to pay $25,000 ended up costing them over $10 million.

Recent exploits are a reminder that “audited” does not always mean “secure.” I recently completed deep security research across multiple DeFi protocols and identified serious architectural weaknesses during analysis. The Web3 ecosystem needs more proactive security research before exploits happen, not after. Follow for smart contract security insights, exploit analysis, responsible disclosure updates, and advanced research into DeFi attack surfaces. Stay secure. ⚔️
