HISTORY: 9 years ago today in 2017, 300,000 computers in 150 countries were locked by WannaCry ransomware. Variant two was just released. The ransom demand: $300+ in BTC. For most of the world, it was the first time they'd ever heard of Bitcoin. The attack, later attributed to North Korea's Lazarus Group, put crypto on the front page of every newspaper in the world. 📺: @ABC(CoinDesk)
