Ex-Hacker Explains the Perils of Laundering Stolen Crypto

POLICY WIRE — Global — The world’s largest cryptocurrency exchange, Binance, suffered a significant security breach on Thursday, resulting in the theft of more than $6 billion. Initial evidence points to North Korean hackers as the culprits behind the rapid drain of the funds.

But what happens next? To shed light on the challenges of handling such a massive haul of stolen cryptocurrency, CNN spoke with Ilya Lichtenstein, a former hacker who, along with his wife, pleaded guilty to a $4.5 billion money-laundering scheme in 2023. Lichtenstein, who now claims to be a ‘white hat’ hacker, offered his expert insights.

North Korean hacking operations typically exploit the weakest links, often targeting vulnerable individuals rather than the heavily fortified main systems. ‘You need to secure all the entrances, not just the front door,’ Lichtenstein emphasized, highlighting the importance of comprehensive security measures.

The stolen funds are now in a race against time. ‘It’s like investigating a murder; the first 48 hours are critical,’ Lichtenstein explained. The hackers must迅速行动，将资金拆分成更小的部分，混入其他资金，以避免被追踪和冻结。AI技术的快速发展使这一过程变得更加复杂。

‘黑客们现在面临着巨大的压力，’Lichtenstein说。‘区块链是公开可见的，任何人都可以进行调查。此外，许多加密货币平台，如Tether/USD，有能力冻结资金，这使得它们并非完全去中心化。’

尽管如此，黑客必须迅速行动，通过交换、混合和转移资金，试图掩盖资金的来源。‘他们必须尽快行动，以避免被冻结或被捕，’Lichtenstein补充道。然而，这一过程充满风险，他形容黑客们‘就像拿着烫手的山芋一样’。

Lichtenstein分享了他自己过去的洗钱技巧，包括在多个交易所注册账户，使用真实和虚假的身份，将资金分成小额存款，并进行‘链跳’，即将资金从一个区块链转到另一个区块链，以此来打破追踪链。

‘AI和技术的发展使得这一切可以以惊人的机器速度自动化，’Lichtenstein警告说。‘这既令人兴奋又令人恐惧。’他强调，犯罪不值得，即使是看似酷的行为，也会带来长期的后果。

‘北朝鲜可能在几个月后将这种技术交到任何人的手中，’Lichtenstein补充道。他指出，目前最先进的模型由OpenAI和Anthropic等公司控制，但开源模型正迅速赶上。
