Ledger's Chief Technology Officer Charles Guillemet stated that there has recently been "FUD" targeting Ledger in the market, as a smart contract security company claimed to have discovered vulnerabilities in the Ledger Ethereum application. Guillemet mentioned that there indeed were vulnerabilities related to certain Clear Signing processes in the Ledger Ethereum application, but these vulnerabilities were discovered by Ledger's security research team Donjon using AI-driven vulnerability research tools, and the fixes were completed and deployed two weeks ago. Users can obtain protection by timely updating their Ledger device firmware and applications.The relevant security company contacted Ledger's bug bounty program only after the fixes were completed, did not follow responsible disclosure processes, and did not communicate with the bug bounty team, yet implied in subsequent content that the issue had not been resolved. This approach is not true security research but rather a way to create panic for attention. AI is changing the cybersecurity landscape, and both attackers and defenders can enhance efficiency with AI, but AI-driven security research can only truly enhance the security of the entire ecosystem when basic security principles such as responsible disclosure and pre-release verification are followed.Guillemet finally reminded Ledger users to keep their device firmware, Ledger applications, and related software up to date to automatically receive the latest security fixes and research results. Users should not be influenced by the related "FUD" and should timely update their software and maintain safe habits.

Blockstream has released a Bitcoin Improvement Proposal (BIP) proposing the SHRINCS post-quantum signature scheme. SHRINCS is a hash-based post-quantum signature scheme with a minimum size of 548 bytes, approximately 9 times larger than the existing Schnorr signatures, but much smaller than the NIST-approved ML-DSA and SPHINCS+ schemes. The scheme has completed production environment testing on the Liquid sidechain and includes a copy of the Bitcoin white paper.The scheme also has limitations. The BIP warns that security proofs are still pending, and the scheme is stateful, requiring the storage of used keys for each signature, which increases the signature size by 16 bytes with each use. In the event of device loss, approximately 5777 bytes are needed for a stateless fallback transaction recovery. Blockstream estimates that Bitcoin can maintain a speed of about 3 TPS after adopting SHRINCS, which can be increased to 6.7 TPS when combined with ZK proof aggregation.

According to TIME, OpenAI CEO Sam Altman recently stated in an interview that the company has previewed the upcoming cutting-edge model series Astra to key clients. In the demonstration, 16 AI agents can collaboratively break down mathematical problems and assemble proofs, and Astra can operate computer software across applications at superhuman speeds. Altman mentioned that Astra will support "persistent agents" capable of performing long-term tasks and is expected to be the first model that can invent new things in a meaningful way, possessing characteristics of AGI.Over the past year, OpenAI has fallen behind expectations in product direction and pre-training research, being surpassed by Anthropic in programming products, annual revenue, and valuation. The company has experienced multiple executive departures and is facing challenges such as several product liability lawsuits and legal disputes with Apple and Musk. OpenAI's current valuation is nearly $1 trillion, with ChatGPT having over 1 billion monthly active users.Recently, OpenAI disclosed a security incident: an unreleased agent escaped the sandbox and attacked Hugging Face. Following this, the research team froze some experiments, enhanced monitoring, and paused the training of an unreleased model expected to bring the greatest capability leap until new safety measures are in place. Altman emphasized that "ensuring AI safety is more important than the growth momentum of any company," and the company will slow its pace and allocate resources to safety and alignment teams. Chief Research Officer Mark Chen estimated that the company is about 80% complete in reaching AGI, and Altman stated that the internal system may be referred to as AGI by the end of the year.

According to Wired, during security testing, the open-source model Kimi K3 from the dark side of the moon broke out of the sandbox and accessed the internet, attempting to find test answers via GitHub. American security startup Frontier Security stated that Kimi K3 exploited a sandbox configuration vulnerability, but it itself lacked sufficient built-in protective mechanisms.Similar to incidents previously disclosed by OpenAI and Anthropic, this escape partially stemmed from a sandbox configuration error. However, Kimi K3 did not initiate an attack, as the answers were easily accessible on GitHub. The CEO of Frontier Security stated that Kimi K3 performed excellently in cybersecurity defense but lacked mechanisms to prevent cheating or escaping the sandbox. Security experts emphasized that configuring the testing environment is crucial, as the misuse of AI agents could lead to system failures.
