Crypto Hacks Down 47% in H1, But Don't Relax Just Yet
Losses from crypto exploits dropped nearly half year-over-year, yet Q2 showed a sharp 59% spike — a warning sign the industry can't ignore.
Good news first: crypto hacks fell 47% in the first half of the year compared to the same period last year, according to blockchain security firm CertiK. If you've been nervously watching your portfolio, that headline probably feels like a relief. But before you kick back, here's the catch — the ecosystem isn't actually getting safer.
Here's why security researchers are still sounding the alarm. In Q2 alone, losses from crypto exploits surged 59% quarter-on-quarter, reaching a hefty $807.5 million. That kind of jump in a single quarter shows just how volatile the threat landscape remains. One bad stretch can erase months of apparent progress, and Q2 was definitely a bad stretch.

Among the biggest culprits behind that Q2 spike were attacks on KelpDAO and Drift Protocol — both tied to North Korean hackers, according to CertiK. State-sponsored cybercrime has become a persistent headache for the crypto industry, and these groups are sophisticated enough to target even well-established protocols. When nation-state actors are in the game, the stakes are a whole different level than your average opportunistic scammer.
The broader takeaway here is that raw annual numbers can be misleading. A 47% decline in H1 sounds impressive, but CertiK's analysis suggests the underlying vulnerabilities haven't gone away — they just haven't all been exploited yet. For everyday crypto users, that means keeping security habits sharp: using hardware wallets, double-checking smart contract approvals, and staying skeptical of too-good-to-be-true DeFi yields.
