According to TechFlow, on-chain analyst Ember's monitoring, CoinStats was attacked last night. Hackers pushed notifications containing phishing links to users through the application, and about 1,590 wallets were affected.
The wallet most affected may be one belonging to Blurr.eth: 3,657 MKR ($8.7 million) was stolen and sold on the chain by the hacker for 2,482 ETH. This caused the price of MKR to plunge from $2,462 to $2,280, a short-term drop of 7%.
