Bloomberg: In response to the surge of "wrench attacks" by cryptocurrency holders, it is driving the growth of related security demand services According to Bloomberg, there has been a surge in "wrench attacks" targeting cryptocurrency holders in the past three years, according to Foresight News. This type of attack uses violent methods such as kidnapping, assault, and even amputation to coerce victims into handing over their encrypted assets. According to a database maintained by Jameson Lopp, co-founder of cryptocurrency security company Casa, there have been approximately 60 recorded attacks of this kind worldwide this year, causing tens of millions of dollars in losses. This number is higher than the approximately 40 cases in 2024, but some people believe that the actual number is much higher than this. Ari Redbord, Global Policy Director at blockchain research firm TRM Labs, stated that violent cryptocurrency theft cases are "severely underreported" as victims often refuse to come forward. In response to the increasingly severe threat, traders have hired security companies to minimize their online traces and delete any personal information that may pose a risk. They also take preventive measures in real life. Security companies like BlackCloak (helping executives protect their online image) and Solace Global (providing personal and cybersecurity services for high net worth individuals) are now also promoting their services to cryptocurrency holders. DeleteMe is a company that helps people clear personal information from the internet, and in the past year, the number of employees of cryptocurrency companies using its service has doubled.
