In the ever-unpredictable landscape of cryptocurrencies, security is paramount. However, Stars Arena, an Avalanche-based protocol, found itself in the eye of the storm just a day after dealing with a non-critical bug. This time, it wasn’t just a glitch; it was a massive security breach that sent shockwaves through the crypto community.
The protocol took to its official Twitter account (X) to deliver a sobering message: their smart contract had been attacked. A stark warning echoed in their tweet, urging users in no uncertain terms: “DO NOT deposit any funds.”

The magnitude of the breach became horrifyingly clear when DeFiLlama data revealed that Stars Arena’s total value locked (TVL) of nearly $2.8 million had been drained in the attack. It was a heist that left the community stunned and raised crucial questions about the vulnerabilities in the crypto space.
Blockchain security experts PeckShield swiftly identified the nature of the attack. The hackers had exploited a vulnerability known as reentrancy within Stars Arena’s smart contract. This technique allowed them to update the weight during the issuance of profiles, enabling the sale of a share at an exorbitantly inflated price of 274,000 AVAX.

The reentrancy is abused to update the weight when the share/ticket is issued so that 1 share can be sold at a much higher price… https://t.co/17CxO3uLbe pic.twitter.com/fouVjevYTs
Stars Arena, despite its relatively recent launch just a few weeks ago, had initially shown promising growth. Within days, it had surged past the $1 million TVL mark, attracting significant attention and investment. However, this security breach serves as a stark reminder of the challenges faced by emerging protocols and the necessity for robust security measures in the crypto world.
As the crypto community grapples with this breach, it serves as a cautionary tale for all participants. Vigilance and security consciousness are not just buzzwords; they are the shields that safeguard assets in the wild west of cryptocurrencies. Stay informed, stay alert, and remember, in the crypto universe, security is your strongest ally.
