Cryptocurrency Exchange, EXMO, victim of DDoS attack after kidnapping of an employee

On December 28, 2017, Exmo was the victim of a distributed denial-of-service attack which temporarily halted transactions on the exchange. This followed the kidnapping of an employee and blockchain expert who was later released after a ransom of $1M was paid.
 
Due to the increased activity and resulting price surges on cryptocurrency exchanges recently, cryptocurrency exchanges and personal crypto-wallets have become heavily targeted in both cyber and physical attacks. This is likely to increase moving forward. NSI advises clients with investments in any form of cryptocurrencies to stay vigilant and increase security measures with the use of complex passwords, two-factor authentication, and the use of off-line wallets.
