September 2025 turned out to be one of the most damaging months this year. Here’s how. 

14 Major Crypto Incidents in September

Crypto security firm CertiK reported that in September, about $155.9 million was lost to exploits, with $26.4 million tied to phishing. There were 14 major crypto incidents (excluding phishing), each causing initial losses of over $1 million, the highest number of such incidents since March 2024.

Rising Cyber Threats in Crypto

CertiK had previously said that the crypto industry faces an “endless war” against hackers, reporting nearly $2.5 billion in digital asset thefts in the first half of 2025.

CertiK co-founder Ronghui Gu noted that as long as there are weak points or vulnerabilities, sooner or later they will be discovered by attackers. He also warned that next year’s hacks could reach billion-dollar levels, emphasizing that while defenses are improving, cybercriminals are also becoming more sophisticated.
