Tackling Crypto Crime
EXMO reported the incident to the London police and will be keeping in contact with the Cybercrime department.
Despite the maturing industry, cryptocurrency hacks and security breaches still occur.
$4 billion was stolen in cryptocurrency in the first half of 2019, with notable incidents including the fall of the QuadrigaCX exchange in which $170 million was lost. Canadian authorities now believe QuadrigaCX was a Ponzi scheme in the first place.
$50 million was stolen in 2020 from DeFi projects alone. Crypto intelligence company CipherTrace reports that crypto crime has slowed this year, although it states that $1.8 billion was still stolen in the first ten months of the year.
As the industry attracts more institutional investment and regulatory scrutiny, the issue of securing exchanges and providing enterprise-grade security measures becomes increasingly important.
