Michele Korver, the first-ever "crypto czar" of the US Department of Justice, was going out on a high note. After an incident on Memorial Day, an affiliate of the renowned "REvil" gang extorted $11 million in Bitcoin (BTC) from meat producer JBS. If REvil succeeds, they may launch a second attack on companies that opted to pay the ransom demand. Businesses who opt to accept a ransom demand are 80 percent more likely to be targeted again.
