Two cryptocurrency exchange portals, DragonEx and CoinBene, have disclosed hacks this week and have both gone into maintenance mode to investigate and improve their infrastructure.
DragonEx is believed to have lost over $1 million worth of cryptocurrency, while CoinBebe's losses are estimated at over $45 million, according to industry observers.
It should be noted that none of the two cryptocurrency exchanges have put out exact figures of the sums they've lost, and none have responded to requests for comments from ZDNet.
The DragonEx hack
The first of the two to admit to a hack was DragonEx. In a message posted on its English Telegram channel, the exchange said it was attacked on Sunday, March 24, when hackers stole part of its funds.
DragonEx sad the hacker transfered funds to other exchanges, but they were able to recover some of the money, but not all.
Earlier today, one of the exchange's administrators posted another Telegram message with the hacker's wallets that are currently storing stolen DragonEx funds.
Accounts in several cryptocurrencies can be seen. It is unknown if the hacker has already converted the funds into other cryptocurrencies, or if these are the funds that he originally stole from DragonEx.
Some of these cryptocurrencies provide web portals where users can view the total funds stored inside the respective wallets. Based on a cursory search, ZDNet was able to identify accounts that stored more than $1 million in various cryptocurrencies, but the hacker is believed to have stolen much more.
Authorities in Estonia, Thailand, Singapore, and HongKong are assisting the Singapore-based exchange with its investigation.
The CoinBebe hack
The second cryptocurrency to have annonced a hack this week is CoinBebe, which admitted to being targeted by hackers earlier today in a tweet.
The platform said that all funds are "100% secure" and promised that if any users lost funds, they'll be compensate in full.
However, on social media, some industry experts have contested the company's assessment that no funds were taken.
Crypptocurrency expert Nick Schteringard said on Twitter yesterday, that the hacker appears to have stolen roughly $6 million in Coinbene Coin and $39 million in Maximine Coin, which it later dumped on the market.
The Coinbene website remains in maintenance mode at the time of writing. Coinbene and DragonEx are ranked 10th and 30th, respectively, based on the past 30 days trading volume, according to CoinMarketCap
Below is a text version of the list of wallets shared by the DragonEx exec.
