2022 is on course to be a record year for crypto hacking as a record amount of digital assets were stolen via crypto hacks in October.
According to data from blockchain security firm PeckShield released on Monday, about $760 million worth of crypto value was looted by hackers and cybercriminals in 44 incidents that affected 53 protocols in October.
However, some of the exploited protocols recovered $100 million, a fraction of that sum within the same period.
PeckShield reported that $2.98 billion of crypto assets had been stolen in 2022, almost double $1.55 billion, the total value of crypto stolen in 2021,

Binance co-founder and CEO Changpeng Zhao (“CZ”) disclosed that hackers accessed a cross-chain bridge where users transfer digital assets from one blockchain to another. The hackers created 2 million BNB tokens out of thin air.
The PeckShield report listed the Mango Markets Defi protocol as the second biggest loser in October. However, the exploiter agreed to return some of the funds.

For the crypto lender, Mango Markets, the attacker, Avraham Eisenburg, claimed actions behind the exploit were legal after an oracle price manipulation. Following a community vote, an agreement was struck, and Eisenburg walked away with $47 million…
