Crypto Hacks: $1.26 Billion in the Third Quarter

Between July and September 2026, attackers pulled roughly $1.26 billion out of the crypto market. The figure comes from the security firm CertiK, which counted 247 security incidents in the third quarter. That means almost half as much drained away in three months as in the whole year to date, for which CertiK arrives at around $2.68 billion.

For you as an investor in Germany, this is not an abstract statistic. The big cases of the quarter did not hit exotic niche projects but one of the largest trading platforms in the world and an established sidechain. This piece puts the figures in context, separates the two competing counts from one another, and shows where you can genuinely check your own custody.

What CertiK counted for the third quarter of 2026

CertiK keeps a running tally of attacks on blockchain protocols, trading venues and wallet infrastructure. For the third quarter of 2026 the firm puts the damage at around $1.26 billion from 247 incidents. On the same count, the second quarter stood at $819.4 million from 219 incidents. The total has therefore risen by a good half, the number of cases by just under thirteen percent.

That ratio is the real finding. There were not substantially more attacks, but the successful ones were markedly larger. Average damage per incident climbed from around $3.7 million to about $5.1 million. Anyone who leaves crypto assets on a platform shares their risk with every other customer of that same platform, and that is precisely where the large sums sit.
