Cryptographic scammers have evolved their tactics. According to a recent report by the Blockchain Certik security company, Hack Crypto have evolved in the social engineering of the victims to reveal sensitive information instead of targeting the vulnerability of the contract.
So far in 2025, over 2.2 billion dollars have been stolen by investors by cryptocurrency hackers. Certik’s report suggests that a considerable part of these cryptographic hacks came from phishing attacks and portfolio compromises.
In addition, the report underlines that some main accidents between numerous hacks have caused significant losses and can be traced back to authors supported by the state or defects of critical infrastructure.
In particular, Certik mentions that attacks on Bybit and Cetus Protocol have somehow distorted the data since they represented about 1.78 billion dollars of total losses, pushing these numbers of 2025 above last year.
Bybit has undergone the largest attack on its assets this year in February 2025, which left a hole of $ 1.5 billion in her pocket.
In the case of the Cetus protocol, a decentralized exchange based on SUL, hackers used falsified tokens and prices manipulation to drain liquidity, leading to a loss of $ 225 million. Sully validators were able to freeze and return $ 162 million with a higher stolen amount.
So far in 2025, chain accidents have led to ~ $ 2.1 billion in losses.
Most of the losses are derived from compromises and phishing of the wallet, with an increase in data loss that is important to remain vigilant. pic.twitter.com/cjm6qfhwqx

Phishing attacks involve crypto scammers who share deceptive bonds with victims to get their sensitive information, such as private keys for crypt wallets, etc.
Ronghui Gu, a co-founder of Certik, believes that the increase in phishing attacks that socially engineers engineer to share sensitive information alludes to cryptographic scammers who change their attack protocols.

The tendency of the portfolio violations becomes alarming
The report suggests that between January and June 2025, cryptographic hackers carried out 334 attacks, for a loss of $ 2.47 billion. Among these accidents, the only portfolio represented $ 1.7 billion from only 34 attacks.
While Certik noticed that the compromises of the private key are in decline, he defined the tendency of the violations of the “alarming” portfolio.
Social engineering patterns have become a serious threat. Schemes like the poisoning of the address do not require any hacking since the victim is induced to send goods to fraudulent addresses of the wallet. Case in question, a Bitcoin whale that falls victim to a phishing scam on April 30, 2025, which cost him a loss of $ 330 million.
Skilizing high -profile attacks on these two exchanges bring total losses to about $ 690 million, which is quite similar to last year, with Ethereum the most targeted blockchain, assisting 175 events related to safety, which represent losses of over $ 1.6 billion.

While scams and hacks increase, physical attacks on private cryptocurrencies owners are becoming more brutal. According to Jameson Lopp, a Bitcoin security lawyer, this year he has already seen reports on 32 attacks of keys (physical attacks), putting 2025 on the right way to overcome the 2021 record of 36. Almost a third occurred in France.
Only in May, the French authorities arrested 25 suspicions related to a rapture ring based in Paris.
The remarkable cases include the January kidnapping and the mutilation of the co-founder of Ledger David Balland during a failed redemption attempt, the imposters posing while the couriers kidnapped the father of a merchant, cut a finger and requested 7 million euros, the kidnappers attempted to take the kidnapped in Arizona.
