One victim, a musician who goes by G. Love, wrote: "I lost my retirement fund in a hack/Scam when I switched my Ledger over to my new computer and by accident downloaded a malicious ledger app from the Apple store. All my BTC gone in an instant." According to him, he lost 5.9 BTC (~$445,000).
Crypto sleuth zachxbt traced some of the stolen funds through Kucoin, a Chinese cryptocurrency exchange that was recently fined and forced to exit US markets over licensing and anti-money laundering failures. "The three largest victims lost seven figures each," he wrote.
Apple removed the malicious app from their App Store on April 13, six days after it had been added.
