The founder of the hardware wallet OneKey, Yishi, announced the launch of a tool to detect whether hardware wallets have been tampered with, called tampered.app. Users can upload photos of the circuit board for detection, supporting OneKey, Ledger, and Trezor, free of charge, without registration, and without saving photos.The tool can mark suspected anomalies, but a normal result does not guarantee complete safety. Yishi stated that tests on approximately 400 photos submitted by users showed an accuracy rate of over 95%.

The founder of the hardware wallet brand OneKey, Yishi, stated that recently multiple users who purchased Ledger hardware wallets through CryptoBilis reported asset theft. Ledger has confirmed that affected devices were implanted with unauthorized hardware, and the cause and scope of the impact are still under investigation. Since CryptoBilis also sold hardware wallets from brands like OneKey, OneKey has terminated its authorized dealer qualifications and will stop adding new dealers effective immediately.OneKey will re-evaluate existing dealers, and those who cannot verify the operating entity or ultimate beneficiaries will have their authorization canceled. A complete list of authorized dealers will be published after the review is completed. From March 1, 2026, to the date of this announcement, users who purchased OneKey hardware wallets through CryptoBilis, regardless of model, activation status, or usage, can apply for a free replacement. If the original model is in stock, a brand new device of the same model will be provided; if out of stock, a free upgrade will be given, shipped directly from the official OneKey store without the need to return the old device. Applications will be accepted until December 31, 2026, and must be submitted through OneKey's official website customer service or help.onekey.so with proof of purchase, device model, and usage status.OneKey reminds users that unactivated devices should refrain from activation and apply for a replacement directly; users who have used the device and have assets should proactively treat the old mnemonic phrase as potentially compromised, and transfer assets to a wallet created with a brand new mnemonic phrase as soon as possible, and should not import the old mnemonic phrase into a new device.

The security team of the open-source wallet provider OneKey successfully replicated the exploitation of a vulnerability in the old version of the Ledger Ethereum application in a laboratory environment. OneKey's founder and CEO Wang Yishi stated that they executed a "transaction replacement attack" on Ledger Ethereum application version 1.22.1 by exploiting a previously patched vulnerability, allowing attackers to overwrite pending transactions while users review legitimate transactions.Ledger responded that exploiting this vulnerability requires controlling the communication between the device and the host, such as through malware, compromised wallet software, or malicious web pages. Ledger has added application layer protections in the Ethereum application version 1.22.2 released on August 13 and fixed the underlying issue in Secure SDK 26.6.1 on August 21. Ledger emphasized that no users were hacked as a result; this was merely a replication of the vulnerability in a laboratory environment.This security test occurred after the Coldcard vulnerability incident. Previously, the Coldcard wallet had a firmware vulnerability that posed security risks to some mnemonic phrase generation, but Ledger stated that its devices were not affected by this vulnerability because recovery phrases are generated by a certified random source built into the device's secure chip. The vulnerability replicated by OneKey is unrelated to mnemonic phrase generation but affects the way transactions are processed during the signing process.

OneKey founder Yishi posted on platform X: "Pay attention to the short OI (open interest) congestion around 75,000. Once a crowded short + passive delta buying from market makers creates positive feedback, a classic gamma squeeze may occur, where short liquidity reverses and becomes fuel for the bulls."

ChainCatcher news, according to OneKey's Chinese Twitter, regarding the recent "Milk Sad incident" involving a random number vulnerability, the OneKey team clarifies that this vulnerability does not affect the security of the mnemonic phrases and private keys of OneKey's software and hardware wallets.The vulnerability originates from the Libbitcoin Explorer (bx) version 3.x, which uses a pseudo-random number generator based on system time and the Mersenne Twister-32 algorithm, with a seed space of only 2³² bits. Attackers can derive private keys through prediction or brute force. The affected range includes some older versions of Trust Wallet and all products using bx 3.x or older versions of Trust Wallet Core. OneKey states that its hardware wallets use EAL6+ secure chips with built-in TRNG true random number generators; older devices also pass SP800-22 and FIPS140-2 entropy tests; the software wallet uses system-level CSPRNG entropy sources to generate random numbers, meeting cryptographic standards. The team emphasizes that users are advised to manage assets using hardware wallets and should not import mnemonic phrases generated by software wallets into hardware wallets to ensure the highest level of security.

ChainCatcher message, Curve ecosystem contributor haowi.eth posted on the X platform stating: "Recently, Onekey and its founder Wang Lei (also known as yishi) issued a joint statement accusing me of making false statements regarding the so-called Resupply vulnerability incident. This incident has triggered a series of personal attacks and false accusations. This matter is unrelated to any DeFi project or industry risk. I deny the joint statement publicly issued by Onekey and Wang Lei, as well as the subsequent remarks. Making unfounded or unsubstantiated statements is meaningless. I have not been legally sanctioned in any country. Any statements should be based on irrefutable facts. I reserve all rights and will take action based on my judgment. As a member and investor of the Curve community, I express my views and facts to defend my own and other investors' legitimate rights and interests. I will actively protect my rights through legal means and will not tolerate any malicious defamation and personal attacks."haowi.eth stated that Yishi and 3D previously accused Curve of being the problem on Twitter due to losses in the Resupply insurance pool and made many irresponsible remarks, to which he refuted one by one, and then received a lawyer's letter a couple of days ago.

ChainCatcher message, OneKey founder Yishi posted a warning on platform X, advising users to upgrade their iOS and macOS to the latest version as soon as possible. Apple has a high-risk 0-day vulnerability in the wild, which is not a PoC; it is being used to exploit CVE-2025-43300. The vulnerability works by sending a specially crafted image to the user, which can lead to out-of-bounds read and write of the user's device memory, potentially resulting in direct remote RCE. There are already reports of payloads being executed.In the comments, a user used Grok for verification, and Grok replied: "CVE-2025-43300 is a real Apple zero-day vulnerability affecting iOS, iPadOS, and macOS. Processing malicious images can lead to out-of-bounds writes and potential remote code execution. Apple has confirmed reports of sophisticated attacks targeting specific individuals and released an update in August 2025 to fix it (e.g., iOS 18.6.2). Immediate updates are recommended.

ChainCatcher news, OneKey founder Yishi posted a screenshot of being blacklisted by Curve Finance with the caption "Graduated."Previous report, OneKey founder Yishi spoke out about the Resupply attack incident, calling on projects like Curve to refund user losses.

ChainCatcher message, the encryption wallet provider OneKey released a statement in its X community stating that it has never incited, organized, or manipulated any KOL or user in any form to launch public opinion attacks against Curve or any project. In response to the malicious accusations and false statements spread by certain individuals on current social platforms, OneKey will pursue legal accountability and will not tolerate such behavior.In addition, founder Yishi is participating in the investment entirely in a personal capacity, which is a personal action, and no official resources from OneKey have been involved in this project.At the same time, all products of OneKey are designed to be open source, with no backdoors, and have been fully audited by professional security teams such as SlowMist.

ChainCatcher news, OneKey founder Yishi tweeted, "So far, I haven't seen Resupply take any action to alert or track down the hackers, not even bothering to put on a show by calling for the hackers to return the stolen funds. Instead, they are directly targeting the victim users. Their first reaction after being Rugged was to reach into the users' pockets for money, extending the unlocking period, preventing withdrawals, and various insults towards users in the community, kicking people out, muting, and racial discrimination... After so many years in DeFi, I've really opened my eyes, there's your kind."In addition, SlowMist founder Yu Xian added, "The project party is the first known in history to not make any statements or offer bounties. If I were the attacker, I would also be confused. Why hasn't the project party made a statement yet? Am I a black hat hacker or a white hat?"

ChainCatcher news, OneKey founder Yishi publicly stated about "Curve ecosystem DeFi protocol Resupply suffering a price manipulation attack resulting in a loss of $9.6 million," demanding that Curve provide a fair solution for every investor and return the user funds lost due to serious technical errors by the project team.Yishi revealed that he is one of the three major investors in Resupply, and the losses from this incident amount to millions of dollars. He accused the team of banning reasonable questioners on Discord and lacking the necessary accountability. He emphasized that the vulnerability stemmed from the failure to destroy the initial shares when deploying the ERC4626 vault, allowing attackers to mint shares at almost zero cost and drain the vault, which constitutes a protocol-level design and deployment error.Yishi stated that it is unreasonable for the Resupply team to shift the losses onto the insurance pool depositors, as the insurance pool is meant for black swan events and market fluctuations, not to cover the team's technical negligence. He also pointed out that Curve, Convex, and Yearn had participated in supporting Resupply in various forms and had gained actual benefits from it, and should not shirk responsibility afterward. He called for the relevant parties to bear the necessary costs and return user assets.In response to the incident, Curve stated this morning, "Although Resupply was not developed by the Curve team, its creators are experienced, and we believe they will do their best to address the issue. The insurance pool is intended to provide protection for such security incidents, and any recovered assets should be prioritized for processing."
