【Blockchain Rhythm】The USDC Fusion Optimizer treasury on the Arbitrum network was recently reported to have a security vulnerability. The IPOR team received an alert on January 6th and discovered a specific technical flaw—resulting in a loss of $336,000 worth of USDC.

It is important to note that the scope of this vulnerability is actually not widespread. It targets a particular version configuration within the Fusion Vault. Due to the unique architecture of this system, it is the only insurance vault vulnerable to such an attack. In terms of risk proportion, this loss accounts for less than 1% of the total funds guaranteed by Fusion.

In response, the IPOR DAO and Security Alliance have coordinated efforts to track down the relevant funds. More importantly, the IPOR DAO has committed to covering the shortfall from its own treasury to ensure that all affected depositors receive 100% compensation. This quick emergency response and full reimbursement approach may help alleviate market concerns.

$360,000 lost, but it sounds so good—"less than 1%"... I've heard this kind of rhetoric in how many projects.

Another hot security news: 360,000 lost, but only 1%? No matter how you look at this ratio, it sounds a bit mysterious.

It's Arbitrum again... This time, 360,000 is gone. Luckily, it's less than 1%, right? Otherwise, it would be a disaster.

bruh, 33.6k gone just like that... and they're telling us it's "only 1%" like that makes it feel better lol. been there, lost that, ngl this is exactly how it starts with these "isolated vulnerability" claims. next thing you know health factor's tanking across the board. not saying panic but... maybe check those vault configurations? just saying.

360,000 is gone, and it's said to be less than 1%. This number game is really skillful... But speaking of vulnerabilities targeting specific versions, the defense seems to be ridiculous.
