佛罗里达州一名退休人士（化名「Julia Goodwin」）因加密货币上涨，使净资产在短时间内跃升至300多万美元；但在2021年遭SIM卡交换攻击后，她的资产在4分钟内被做出19笔转帐，损失约90%。2022年9月，3名持枪歹徒闯入住处逼问钱包密码并准备施虐；患晚期帕金森氏症的丈夫触发警报，歹徒抢走装置与财物后逃离。此案凸显不可逆、由用户掌控的转帐机制，如何把线上盗窃推向线下胁迫。

证据显示，该团伙分为线上「技术组」与入室「打手组」：技术组可抽走高达70%的战利品，而单名打手的分成可能低至6%。首脑Jarod Seemungal供称，他与同伙入侵逾100支手机，平均每次SIM交换获利1万美元。2021年3月，他们从Julia在BlockFi的帐户窃走28枚比特币与1,108枚以太币；他分得约150万美元，并以15万美元购买BMW。

自2020年以来，全球已记录逾215起「实体加密攻击」，且2025年的数量几乎较2024年翻倍。该团伙至少评估8个美国州的目标；其中2023年4月12日北卡罗来纳州一案，在Coinbase冻结最后一笔9,145美元转帐前，已转出合计156,853美元。受害者每月支付29.99美元购买保护方案；Coinbase在2024年12月付费订户已逾60万。盖洛普民调显示，美国投资者中有17%持有加密货币，约为四年前的近三倍。

A Florida retiree, “Julia Goodwin,” saw crypto gains push her net worth above $3 million, then lost about 90% in a 2021 hack: 19 transfers in four minutes after a SIM-swap. In September 2022, three armed intruders demanded her wallet passwords, planning torture, while her husband with advanced Parkinson’s triggered a panic alarm and they fled with devices and valuables. The case illustrates how irreversible, self-custodied transfers can convert digital theft into direct physical coercion.

Evidence showed the gang split into online “techs” and onsite “goons”: techs took up to 70% of loot, while individual raiders could get as little as 6%. Leader Jarod Seemungal testified he and partners hacked over 100 phones, averaging $10,000 per SIM swap. In March 2021 they stole 28 Bitcoin and 1,108 Ether from Julia’s BlockFi account; his cut was about $1.5 million, funding a $150,000 BMW.

Since 2020, more than 215 physical crypto attacks have been documented worldwide, with 2025’s count nearly doubling 2024’s. The crew targeted at least eight US states; one April 12, 2023, home invasion in North Carolina moved $156,853 before Coinbase froze a final $9,145 transfer. A victim paid $29.99/month for a protection plan; Coinbase had over 600,000 paid subscribers by December 2024. A Gallup poll finds 17% of US investors hold crypto, almost triple four years ago.
