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.
