CertiK Reports $2.47B Crypto Stolen in 2025 Hacks

According to a new report by CertiK, over $2.47 billion in crypto assets were stolen in the first half of 2025. The largest incident involved Bybit, losing $1.5 billion in a single attack.

The main players include Ronghui Gu of CertiK and investigator ZachXBT. CertiK reported escalating attacks on wallets and noted phishing as a key method.

The crypto community faces heightened risks with increased scrutiny on exchanges. Public accusations, such as those by ZachXBT concerning Crypto.com, suggest a broad need for improved transparency.

Financial impacts are significant, with a $1.7 billion loss from wallet compromises. Security weaknesses in Ethereum have led to calls for reinforced infrastructure against future attacks.

Evolving attacker patterns show that security measures may temporarily hinder threats, but persistent vulnerabilities remain. Ronghui Gu emphasized the asymmetric conflict in cybersecurity, predicting further sophistication in approaches.

“As long as there’s a weak point or some vulnerabilities out there, sooner or later they will be discovered by these attackers. So it’s an endless war.” — Ronghui Gu, Co-founder, CertiK

Analysts suggest regulatory and technological advancements could mitigate risks. However, as attack patterns evolve, there is a pressing need for improved corporate accountability and defensive strategies. Historical trends show yearly increases in the scale of such incidents.
