Stars Arena, a decentralized social application operating on the Avalanche blockchain, disclosed it was the victim of a $2.9 million cyber attack that occurred this Saturday. The exploit targeted a weakness in the smart contract infrastructure of the platform. In a formal announcement via X (previously known as Twitter), the Stars Arena team identified the incident as a “significant security infringement” and advised users to cease all deposits during the ongoing investigation.

An initial evaluation by Peckshield, a firm specializing in blockchain security and data analytics, revealed that the assailants utilized a reentrancy attack on the Stars Arena shares contract. This allowed them to manipulate asset prices on the platform to their advantage.

Peckshield’s statement read:

The assailants exploited the reentrancy vulnerability to alter the weight during the issuance of shares or tickets, enabling a single share to be sold at an elevated price—approximately 274,000 $AVAX.

Prior to this incident, Stars Arena had identified and mitigated another security flaw, cautioning that the platform had been in the crosshairs of bad actors intending to defraud users.

Subsequent Actions

Emin Gün Sirer, the founder and CEO of Ava Labs, downplayed the severity of the breach, expressing confidence that the platform’s reputable standing and network could facilitate the recovery of the stolen funds.

Gün Sirer commented:

The platform has garnered significant support and has a product that has demonstrated its market viability. The sum involved is relatively minor, being just $3 million. I have full confidence that the vulnerabilities will be addressed. The team needs appropriate time to implement the requisite code modifications.

Subsequently, Stars Arena confirmed it had procured the necessary funds to reimburse users and enlisted the services of a white-hat development team to swiftly conduct a comprehensive security assessment.

The platform also declared its intention to recommence operations with restored funds, pending the completion of an exhaustive security audit, although it refrained from specifying a timeline for the same.

Good on Stars Arena for securing funds to make users whole, but seriously this shouldn’t have happened in the first place. Smart contracts need to be, well, smarter.

Stil no timeline for when things are gonna be back to normal? Not a good sign imo.

BlockchainBetty October 10, 2023 - 1:23 am

Stars Arena is back to square one, I guess. Security audits should’ve been their first step, not a reactionary measure.

TechSavvySam October 10, 2023 - 2:32 am

Emin Gün Sirer seemed to downplay the whole thing. Only $3m he says, but 3 million is 3 million. In this business, reputation is everything.
