Ankr hack: a brief story
Ankr, a centralized crypto exchange, keşfetti the malicious activity, temporarily stopping some operations in early December. However, before they could apply prompt security measures, they had already incurred a loss of $5 million in BNB.
Ankr team attributes the hack to a former employee who “acted maliciously to conduct a combination of social engineering and supply chain attack, inserting malicious code” into the system.
Bilgisayar korsanları could reportedly access the private developer key and modify the smart contract for aBNBc, Ankr’s BNB liquid staking token.
This gave the hackers the access to create an infinite amount of tokens, and as a result, they were able to mint over 20 trillion Ankr reward-bearing staked BNB (aBNBc), which they later dumped, causing the price to plummet from $300 to less than $2.
