OKEx Suspends ERC20 Deposits on Discovery of Critical Ethereum Smart Contract Bug

“We are suspending the deposits of all ERC-20 tokens due to the discovery of a new smart contract bug – â€ËÅ“BatchOverFlowâ€ââ€�¢. By exploiting the bug, attackers can generate an extremely large amount of tokens, and deposit them into a normal address. This makes many of the ERC-20 tokens vulnerable to price manipulations of the attackers.â€�

İş ciddi ise eth ve tokenleri gömülür.

EDIT :
ERC bugı değil Exchange sitesi bugi diyorlar.. İlgincleşti.

We've temporarily suspended ERC-20 token deposits and withdrawals while we review all smart contracts for exposure to the reported batchOverflow bug. We take any reports of vulnerabilities very seriously to ensure that customer funds remain safe. Thank you for your patience!

Due to a potential issue detected in ERC20 smart contracts, we initiated an internal inspection. All deposits and transfers on ERC20 tokens will be getting online in accordance with the results of the inspection. Please refer to the System Health page for online status.

The current problem with some ERC20 tokens comes just after MyEtherWallet reported yesterday that around $150 mln ETH was stolen in an unrelated DNS hack.

Dün myetherwallet dan DNS atak ile bir sürü ether çalmışlar.
