Description of the event: Klever published a report on an external security incident on July 12. All wallets affected by the suspicious activity on July 12 were reported to be affected by a known vulnerability caused by low-entropy mnemonics. It's important to underscore that this issue is not exclusive to Klever. Reports indicate that users of multiple wallet providers are affected. All the wallets involved were imported into Klever Wallet K5. These wallets had not been originally created using Klever Wallet K5, instead all the wallets were created using an old and weak pseudorandom number generator (PRNG) algorithm as their entropy source. This algorithm was commonly used in early versions of various cryptocurrency wallet providers, which relied on the Javascript platform. The use of such a weak PRNG algorithm can significantly compromise the security and unpredictability of the generated keys, potentially making them more vulnerable to attacks or unauthorized access. Klever strongly recommends immediately migrating old wallets to new wallets created on Klever Wallet K5 or Klever Safe.

Description of the event: According to The Block, cybersecurity firm Unciphered claims it was able to hack into hardware-encrypted wallets powered by Trezor T models. In a YouTube demo, Unciphered showed exploiting the wallet vulnerability to extract the mnemonic private key from the wallet, saying the attack is only feasible if the attacker has physical access to the hardware wallet. Trezor CTO Tomáš Sušánka responded: "This appears to be a vulnerability called an RDP downgrade attack, which requires extremely sophisticated technical knowledge and advanced equipment. Even with the above conditions, Trezor can pass a powerful passphrase, making RDP downgrade attacks ineffective.” Trezor added that they have taken the important step of developing a new secure element for hardware wallets with their sister company Tropic Square to solve future problems.

Description of the event: According to the official WeChat account of Ping An Xuhui, employees Zhang, Dong, and Liu from Company A decided in early March 2023 to insert a backdoor program into a certain cryptocurrency wallet software to obtain users' private keys. The three individuals illegally obtained over 27,000 mnemonic phrases and more than 10,000 private keys, successfully converting over 19,000 digital wallet addresses. In April 2024, the Xuhui District People's Court sentenced Liu, Zhang, and Dong to three years in prison for the crime of illegally obtaining data from a computer information system and fined each of them 30,000 RMB. It is worth noting that Company A is suspected to be the former Huobi company. In an exclusive report by WuShuo in 2023, it was revealed that due to the installation of trojans by former employees, some users' mnemonic phrases or private keys of iToken (formerly Huobi Wallet) were leaked. HTX responded that the trojan installation was the personal act of former Huobi employees before the acquisition, leading to the theft of others' mnemonic phrases and private keys.
