Last week, police in Ukraine working alongside other countries' authorities announced that they had arrested several people connected to a ransomware gang that's been hacking and extorting dozens of victims in the last few months. These arrests could have been a big blow for the gang known as Cl0p. But less than a week later, the hackers published leaked data from a new victim, showing that the arrests have not slowed them down. 

On Thursday, the popular cryptocurrency exchange Binance published a blog post detailing its role in the bust and confirming that the people arrested in Ukraine were indeed the ones whose job was to cashout and launder cryptocurrency and money for the Cl0p gang. The company called the group FANCYCAT in the blog post, and described it as a group that's been "operating a high-risk exchanger; and laundering money from dark web operations and high-profile cyber attacks such as Cl0p."
