Reproduced exploits

Exploits rebuilt as runnable proof-of-concept code by DeFiHackLabs, each explained from the code: the vulnerable function, the missing check, and the order of the attack.

Method, and what this does not cover

Written up since 15 Oct 2025, not all time
These are the incidents logged since our feed started, each researched from its original report and further sources. For an all-time table with loss figures on everything, DefiLlama is the better source and this page will not pretend otherwise.
Losses are as reported, and 33 carry a dollar figure
Of the 42 reported incidents, 33 have a loss in dollars as their sources reported it, $1.1B between them; none is independently verified, and where outlets disagree each write-up says so. The others are collapses and shutdowns with no total, or thefts whose total was never published. The 133 reproductions state their loss as DeFiHackLabs measured it, in tokens or ETH as often as dollars, and sometimes as the attacker’s gain rather than the protocol’s loss. Those figures are quoted, never converted.
Every source is listed
Each write-up is Alphaday’s own, drafted from the sources and reviewed by a person before it is published. Every page links the original report and lists every outside page it was written from, so a figure or a date can be checked in one click.
