SynapLogic contract suffers flash loan attack, 193 abnormal transactions expose a new minting vulnerability

The security monitoring team detected a large-scale abnormal transaction in the SynapLogic ecosystem. Attackers used flash loans to carry out arbitrage attacks, successfully minting 16,000 SYP tokens and repaying the loan. This incident exposed security vulnerabilities in the contract design, reminding project teams to strengthen audits and users to stay vigilant.

【Blockchain Rhythm】The security monitoring team has detected a large-scale abnormal trading activity in the SynapLogic ecosystem. Attackers used a series of coordinated newly created addresses to execute a carefully designed arbitrage attack through the flash loan mechanism.

The specific method is as follows: after borrowing 1 ETH, the attacker repeatedly calls key functions of the SynapLogic related contracts, successfully minting 16,000 SYP tokens. Then they quickly repay the ETH, completing the entire attack process. Since the operations originate from multiple brand-new addresses, it is difficult for traditional risk control systems to detect.

This incident triggered a total of 193 suspicious transaction records. It exposes current issues in some projects’ contract design—insufficient protection against large temporary funds like flash loans. Similar attack patterns have occurred multiple times in the DeFi space, reminding project teams to conduct more rigorous security audits before deployment, and community users should also stay alert and exercise caution when participating in protocols with incomplete security mechanisms.

honestly, this is what happens when devs ship contracts without actually thinking through flashloan vectors... like, re-entrancy guards exist for a reason. 16k tokens minted in one tx? that's not a bug, that's just negligent design lol

It's another flash loan scam. How come these projects never learn their lesson? 16,000 coins just appeared out of nowhere? Ridiculous. SynapLogic took a huge loss this time. They should have implemented safeguards long ago.

Another flash loan scam, this time directly minting 16,000 coins... Truly impressive. SYP project team, what are your audits for? 193 transactions went unchecked, how outrageous is that? It's always the same trick every time. When will everyone remember this? Oh my god, can you really farm that aggressively with just 1 ETH? Another new address to evade risk control, need to find a way to upgrade the detection mechanism. DeFi is really a bounty of vulnerabilities, impossible to guard against all. Is this wave of losses for LPs? Quickly check the projects you hold positions in. I've been saying for a long time to add more restrictions on flash loans. Are you listening, builders?

It's the same old flash loan trick again, SYP this time must be very embarrassing --- 193 transactions only discovered? Is the risk control this weak --- 1 ETH can mint 16,000 tokens, the contract designers need to reflect on this --- DeFi is like this, projects without audits will eventually have problems --- Multiple addresses to evade detection… this trick is indeed very skillful --- Every time they say they will conduct strict audits, but next time they still get caught --- SYP is probably going to drop very badly this time --- If basic protections against flash loans can leak, who would dare to use it --- 16,000 tokens just created out of thin air? What is the project team doing --- At this rate, the entire SynapLogic will lose its credibility

It's the same old trick again—flash loan packages. DeFi projects should learn their lesson. --- Borrow 1 ETH to create 16,000 tokens out of thin air. This contract design is really outrageous. --- All 193 transactions are exposed, and no one has noticed. I believe your risk control is suspicious. --- Splitting operations across multiple addresses to evade risk control... Smart is smart, but how come no one is watching with such obvious tactics? --- Every time they say they will strengthen audits, they still get attacked the next time. I'm numb to it. --- The problem isn't user vigilance; it's that these projects didn't do their homework before launching. --- Creating 16,000 tokens out of thin air—Is this a contract or a cash machine?

Another flash loan exploit. How have these project teams not learned their lesson yet? 16,000 coins created out of thin air—it's outrageous… Where's the audit? I just enjoy watching these contract vulnerabilities being exposed, waiting to see how the project teams spin their stories. DeFi ecosystem isn't used to a day without incidents, right? These attack methods are so common now, yet they still appear—what does that say… No one is seriously focusing on security.

Another flash loan vulnerability, these project teams really need to be more cautious --- 16,000 SYP generated out of thin air, this level of absurdity is unbelievable --- 193 abnormal transactions only discovered now? Is the risk control system so weak --- A single ETH causing such a big stir, DeFi really is a hotspot for vulnerabilities --- Where is the promised security audit? Or is this just another hastily launched project --- Multi-address operations to evade risk control, this technique is indeed somewhat clever --- It's always flash loans. When will DeFi projects truly fix this issue --- 196 transactions, friend. Was this an attack or a system crash --- SYP might be about to drop, who would still dare to buy in --- Protecting against flash loans is such a basic thing, yet they still have to use incidents to educate project teams, truly speechless
