Why ‘wrench attacks’ on wealthy crypto holders are on the rise
By ALAN SUDERMAN, AP Business Writer
The headline-grabbing tale of an Italian man who said he was kidnapped and tortured for weeks inside an upscale Manhattan townhouse by captors seeking his bitcoin highlights a dark corner of the cryptocurrency world: the threat of violence by thieves seeking digital assets.
The alleged attempted robbery is known as a “wrench attack.” It’s a name popularized by an online comic that mocked how easily high-tech security can be undone by hitting someone with a wrench until they give up passwords.
Wrench attacks are on the rise thanks in part to cryptocurrency’s move into mainstream finance, Phil Ariss of the crypto tracing firm TRM Labs said in a recent blog post.
“Criminal groups already comfortable with using violence to achieve their goals were always likely to migrate to crypto,” Ariss said.
Some of the crypto’s key characteristics help explain why wealthy individuals who hold a lot of digital assets can be ripe targets for such attacks.
The draw
Cryptocurrencies like bitcoin offer traders full control of their funds without the need for a bank or permission from a government to buy, sell or hold it. The trade-off is that if funds are lost or stolen, there can be no way to get them back.
