The total amount of funds stolen in 2019 amounted to $283 million, compared to $875 million in 2018. However, the total number of attacks doubled to 11 in 2019, compared with 6 in 2018.
Despite the security updates of the exchanges, they remain extremely vulnerable to hackers.
The largest attack in 2019 occurred at Coinbene, in March hackers stole ERC-20 tokens from the hot wallet of the exchange for $105 million. At first, the exchange denied that it had been hacked, but later admitted what happened.
In all three cases, the exchanges covered the losses suffered by their users and that’s very nice.
