Dec. 31 — The U.S. Financial Accounting Standards Board (FASB) plans to explore in 2026 whether certain stablecoins qualify as "cash equivalents" and study accounting for cryptocurrency transactions (including wrapped tokens), according to The Wall Street Journal. The move comes amid the Trump administration’s push for crypto policies and the passage of the U.S. Stablecoin Innovation Act (GENIUS Act). Rich Jones, FASB chair, noted these crypto-related projects are already on the agenda. Previously, in 2023, FASB required businesses to account for cryptocurrencies like Bitcoin and Ethereum using fair value accounting—but the rule at that time excluded NFTs and certain stablecoins.

December 31 ElizaOS founder Shaw weighed in on the “quantum computing threat to Bitcoin” on Monday, pushing back against media hype by noting its actualization is far further off than current coverage suggests. For hash functions like SHA-256, Grover’s algorithm only cuts the search space from 2^256 to 2^128—but 2^128 remains unbreakable with foreseeable technology. Shor’s algorithm can theoretically crack RSA/ECDSA encryption, but today’s quantum computers rely mostly on preprocessing or known-factor optimizations, not a full universal implementation of Shor’s algorithm. Cracking Bitcoin (a real-time network) would demand fast, repeated executions. If that were to happen, all encrypted data would be exposed—making Bitcoin the least of our worries. Modern cryptography has always accounted for future computational advances, and quantum acceleration was anticipated and built into designs decades ago. “Next time you see fear-mongering or hype about quantum computing, remember t

On December 31, SlowMist published its **Q4 2025 Security Incident Analysis**, highlighting two critical threats: a new, more covert phishing tactic and a resurgence in computer malware attacks. ### Key Phishing Tactic Even when users manually type the **correct official domain name**, they may still be redirected to a phishing site. Some victims reported that despite entering the right address, their browsers auto-completed it to an attacker’s forged domain—*not due to user error*, but because attackers previously polluted browser history via ads, social media prompts, or false announcements. Once the phishing domain is stored in the browser’s autocomplete cache, typing the intended address triggers a redirect to a fake site nearly identical to the official one. ### Malware Resurgence Computer malware attacks are on the rise again. Attackers typically stealthily implant malicious programs on users’ devices via: - Phishing links - Social media DMs (direct messages) - So
