Krypton, Ethereum-based network, has recently recovered from a 2-step attack which resulted in a total of 21,465 KR, approximately $3000 USD, being stolen from Bittrex’s wallets. The Krypton team suspects that the attack might have been just a test: attackers might go for other Ethereum-based blockchains such as ETC, for example.

How the attack happened

According to a press release by Stephanie Kent, Krypton’s Founder, and Rocky, cryptocurrency trader, investor and analyst, attackers used Double-Spending to steal the KR from Bittrex.

After the attack, all deposits and withdrawals on both Bittrex and Yobit were disabled in case of another attack on the network and Krypton-accepted exchanges.

Kent states:

“This attack may be a “dry run” intended as proof of concept before targeting other Ethereum based blockchains. Shift, another Ethereum type coin, was also targeted by a similar 51% attack last week. Ethereum based blockchains are being targeted predominantly because they’re easy to fork and manipulate offline, while being used in conjunction with DDoS attacks.”https://cointelegraph.com/news/test-attack-on-krypton-ethereum-classic-might-be-next
