美国财政部首次将数字货币地址列入制裁名单

两名伊朗人被指控参与了名为"SamSam"的全球勒索软件攻击,勒索金额达数百万美元,美国财政部将与这两人相关联的两个加密货币地址公之于众。

美国财政部在公布刑事起诉书当天宣布了这一举措,这也是外国资产控制办公室(后文简称OFAC)首次将数字货币地址归与犯罪嫌疑人公开关联到一起。这也表明联邦政府在追踪通过匿名加密货币实施洗钱和其他犯罪活动方面迈出了新的一步。

根据财政部报告,伊朗人Ali Khorashadizadeh和Mohammad Ghorbaniyan使用两个比特币地址进行了7000笔、总价值数百万美元的交易,并帮助司法部起诉的另外两名伊朗人将SamSam勒索软件攻击中获得的数字货币兑换为伊朗里亚尔。

该部门还发布了相关指引,指导企业处理和限制受OFAC制裁的数字货币以及如何以及何时通知受影响客户。

加密货币在一系列网络和金融犯罪中扮演了越来越重要的角色,跟踪金融交易变得越来越困难,因此过去一年中,美国财政部、司法部和国税局都表示有意加强对加密货币的监管。今年早些时候,美国国税局与加拿大、英国、澳大利亚和荷兰合作,以解决频繁使用加密货币洗钱、购买非法产品和逃税问题。

11月18日,副检察长Rod Rosenstein在国际刑警组织大会上发言表示,"必须落实减轻新技术风险的政策,阻止虚拟货币被犯罪分子、恐怖主义金融家或制裁者滥用。"

虽然此举是联邦政府处理与网络和金融犯罪相关的数字货币方面的新举措,但尚不清楚地址标记能否起到阻断Khorashadizadeh和Ghorbaniyan及其他团体潜在犯罪行为的作用。

安全公司FireEye网络犯罪分析经理Kimberly Goody在一封电子邮件中表示,公开这两个地址"可能没有多大影响,尤其是从长远来看。""如果想继续实施犯罪行为,实施者可以使用其他钱包地址。此外,将犯罪行为公之于众通常会导致实施者更换战术、技术和程序,使检方更难追踪入侵。"

The Treasury Department has publicly flagged two cryptocurrency addresses associated with two Iranian individuals indicted for their role in a worldwide, multimillion dollar ransomware campaign dubbed "SamSam."

The move was announced in conjunction with a criminal indictment unsealed the same day and represents the first time the Office of Foreign Assets Control has ever publicly attributed a digital currency address to individuals in a criminal scheme. It also represents a new step in the federal government's efforts to track money laundering and other criminal activity conducted via anonymous cryptocurrencies.

According to a Treasury release, two Iranian individuals, Ali Khorashadizadeh and Mohammad Ghorbaniyan, used a pair of Bitcoin addresses to conduct 7,000 transactions worth millions of dollars and helped two other Iranian individuals indicted by the Department of Justice convert digital coins derived from the SamSam ransomware attacks into Iranian rial.

The department also released updated guidance around how businesses should treat and block digital currencies subject to OFAC sanctions and how and when to notify affected customers.

For the past year, Treasury, DOJ and the IRS have all expressed interest in stepping up regulation and monitoring of cryptocurrencies, with officials arguing that they are playing an increasing role in a range of cyber and financial crimes and make it more difficult to track financial transactions. Earlier this year, the IRS partnered with Canada, the United Kingdom, Australia and the Netherlands to tackle the growing use of cryptocurrencies to launder money, purchase illegal products and evade taxes.

"To prevent virtual currency from being abused by criminals, terrorist financiers, or sanctions evaders, all of us must implement policies that mitigate the risks posed by the new technology," Deputy Attorney General Rod Rosenstein said in a Nov. 18 speech to the Interpol General Assembly.

While the action represents a new step for the federal government's treatment of digital currencies associated with cyber and financial crimes, it's not clear whether flagging the addresses will meaningfully impede any potential future criminal operations by Khorashadizadeh and Ghorbaniyan or other groups who face similar action.

Kimberly Goody, manager for cyber crime analysis at threat intel firm FireEye, told FCW in an email that outing the addresses "might not have much impact, particularly in the long run."

"If they choose to continue operations, the actors could just obtain and use other wallets," said Goody. "Further, public outing of operations generally leads to changes in actor tactics, techniques, and procedures to make attribution of intrusions to them more difficult."
