"The 150% increase in crypto theft and fraud reflects how criminals are adapting for bigger and better scores," Dave Jevans, CipherTrace chief executive officer, told Reuters.
"Criminals chase money and the money is right here and ripe for the taking. Little attacks are often easy to defend against, but targeted attacks are far more lucrative," he added.
Cryptocurrencies have attracted intense regulatory scrutiny around the world, as developers and market participants in the space seek to push this asset class into the mainstream.
Two large thefts were the main drivers for the surge this year, CipherTrace said.
One of the frauds saw users and customers lose $2.9 billion from an alleged Ponzi scheme involving crypto wallet and exchange, PlusToken.
The other significant fraud this year was the $195 million that customers lost from Canadian crypto exchange QuadrigaCX following the unexpected of its 30-year-old co-founder and CEO, Gerald Cotten. "Even without the two biggest thefts and scams, we are still witnessing many multi-million dollar crimes," Jevans said. "There is a relatively consistent increase in criminal activity year over year and we don't expect that to change overnight."
He added that crimes valued under $5 million are often underreported, as exchanges and police teams focus on the bigger more existential threats to businesses.
