SlowMist: ONTR token contract access control vulnerability resulted in a loss of approximately $98,000.

CoinFeed reported on May 29 that, according to SlowMist monitoring, the ONTR token contract suffered a loss of 49.4801 WETH, worth approximately $98,000, due to an access control vulnerability in the "onlyOwner" modifier. The attacker (0xe806...b760) exploited this vulnerability, bypassing permission checks when "owner" was "address(0)", calling "transferOwnership()" to set the attacker's contract as owner, then calling "desertJasper()" to add the hidden balance to the queue, and finally calling "glenFlash()" to execute "ashBud()", directly increasing the address balance by 1e30 basic units without increasing "totalSupply".
