Blockchain Capital was stolen from USD 6.3 million in encrypted assets due to a SIM card swap attack in May

Odaily Planet Daily News Bart Stephens, co-founder of the encryption venture capital firm Blockchain Capital, suffered a SIM card exchange attack in May this year, losing $6.3 million worth of Bitcoin, Ethereum and other cryptocurrencies. Stephens has filed a lawsuit against the "perpetrator" hacker Jane Doe. It is understood that SIM swapping attacks typically rely on hacking manipulation or "social engineering" to trick mobile phone network customer service operators into divulging victims' personal information. The hackers then use that information to pass security tests, porting the victim's phone number to a new SIM card and phone under their control. (Forbes)
