1. Mt. Gox (2014)

The first few months of 2014 were a surreal time for the world of crypto.

It started on January 10, when became the first online retailer to accept bitcoin as payment. Then, on February 1, the price of bitcoin spiked to what, at the time, felt like the ridiculous level of $813. Then, on March 6, Newsweek published a (since discredited) story claiming to have uncovered the identity of the pseudonymous Satoshi Nakamoto.

Suddenly the world was paying attention to this formerly obscure phenomenon.

What topped it all off, was the news, on February 24, that the Mt. Gox bitcoin exchange — host to about 70% of all bitcoin trading in those days — had been hacked and 760,000 BTC, about 6% of the total supply at the time, had been stolen. A lack of understanding of the nature of crypto caused many journalists at the time to mistakenly report that Bitcoin itself had been hacked. Panic ensued.

Mt. Gox promptly declared bankruptcy and the nearly $500M purloined (worth closer to $15B today) was never recovered. Too bad Mt. Gox didn’t have insurance protecting its customer’s assets from that sort of event.

Of course, a proper underwriting by crytonative experts, such as those at Evertas, may have detected the security lapses that allowed the hack to occur.

2. Ronin Network (2022)

You’d think that the amounts stolen in crypto exchange hacks would decrease over time, but that’s not the case. The potential reward is too high — especially for a cash-strapped place like North Korea — and the hackers are becoming more and more sophisticated.

On March 29, 2022, the Ronin gaming-based crypto network was hacked and about $620 million stolen.

This included $25.5 million USD, but the bulk of the theft was of Ethereum (ETH). 173,600 ETH was stolen, which is about $595 million USD. The US Department of Treasury examined the cause of the breach and traced it to North Korea’s Lazarus group.

3. Poly Network (2021)

Some huge crypto hacks have better outcomes than others. In the case of the Poly Network hack, a vulnerability was exploited in 2021 and $600 million worth of cryptocurrency was stolen.

This story is an unusual one because the hacker did not merely disappear. Instead, he opened a dialog with Poly and returned $577M of stolen funds. The remaining $33 million in Tether was frozen.

Complicating things slightly, $200 million of the funds that were to be returned were stuck in a multi-sig wallet that Poly and the hacker needed to unlock together. The hacker refused to do his part until Poly agreed to give him a bug bounty of $500,000, and a clear conscience.

The best part of the story? Poly Network eventually gave the hacker a job as a security advisor. As they say, it takes a thief.
