WonderHero, a mainstream multi-platform GameFi for iOS and Android devices has deactivated its services after attackers stole nearly $320,000 worth of Binance Coin (BNB). The WND token’s value plummeted by 50% after the information surfaced online.
WonderHero is one of the many popular games where players earn cryptocurrency and NFT revenue via gameplay. The platform currently has around 11,000 active users.
Last week, PeckShield, a top-tier cybersecurity firm notified WonderHero that their platform was breached. To mitigate further damage, the play-to-earn cryptocurrency platform quickly disabled the game and its website before telling users it was aware of the price drop in WonderHero’s coin.
In an official statement, WonderHero confirmed that “there was an attack on our blockchain bridging system and the attackers managed to get the signature and minted 80 million WND (the in-game cryptocurrency).”
The company explained that attackers targeted their “cross-chain bridging withdrawal.” A cross-chain bridge permits users to transfer tokens, assets, smart contract instructions, and data between blockchains. In recent months, the cross-chain bridge has become a ripe target for hackers, and exploits in it have led to millions of dollars in losses.
In its announcement, the company promised it would work to address the breach on their cross-chain bridge before auditing the entire system and creating a new smart contract, and “fairly” compensating all of its followers with new tokens based on the amount of WND they owned before the hack.
“Users can be assured that their HON, WND, NFT, and accounts on Polygon are safe. WonderHero website, marketplace, game, and other services will be temporarily disabled as the team works on the rectification,” the company said.
A snapshot of users’ assets on the BNB Chain prior to the attack will be taken. WonderHero is committed to not just making the game fun but also keeping the assets of our players safe and we will spare no effort in doing so. The team will conduct checks and leave no stones unturned.”
The incident took place just weeks after another play-to-earn cryptocurrency game, Axie Infinity, was hit by an attack that saw attackers steal more than $600 million worth of crypto. In this case, Sky Mavis, the company behind the game was able to raise 150 million dollars to pay the victims of the hack.
