A $5 million cryptocurrency theft involving South Korean tax officials resulted in an unusual double heist. The original thief confessed to police and returned the stolen funds, but the cryptocurrency was subsequently stolen again by another party.
Self-custody startup Bron has launched a new inheritance feature that leverages guardians and multi-party computation (MPC) technology to help users pass on their crypto assets. The solution aims to address one of the key challenges in cryptocurrency adoption by providing a secure way to transfer digital assets to beneficiaries.
This appears to be a summary article covering multiple important developments in the past 24 hours, including a critical iPhone security exploit, Morgan Stanley's partnership with Coinbase, and a16z's $2 billion fundraising effort. The article serves as a digest of key stories across technology and cryptocurrency sectors.
Researchers present a framework for integrating AI directly into database engines (AIxDB) to reduce overhead and improve security compared to exporting data to separate ML runtimes. The paper addresses technical challenges including query optimization, resource management, and security controls needed for effective AI-database integration.
The Bank for International Settlements has issued a warning that criminals may prefer using an offline digital euro central bank digital currency (CBDC) over traditional cash for illicit activities. This highlights potential security and regulatory challenges that could arise with the implementation of offline CBDC functionality.
Robinhood's Head of Crypto announced the company is building its own Ethereum Layer-2 network to serve mainstream users, citing ETH's superior security and liquidity advantages over standalone Layer-1 chains. The strategy aims to bring traditional assets like stocks on-chain while leveraging Ethereum's established decentralized infrastructure.
Former LAPD officer Eric Halem was convicted of stealing $350,000 worth of Bitcoin by handcuffing and threatening to kill a teenager. This case highlights the ongoing security risks and criminal exploitation of cryptocurrency holders.
Former LAPD officer Eric Halem was convicted by a Los Angeles jury for kidnapping and robbery after he and three accomplices posed as police officers to steal $350,000 in Bitcoin from a 17-year-old victim during a 2024 home invasion. The case highlights ongoing security risks and criminal targeting of cryptocurrency holders.
Former LAPD officer Eric Halem was found guilty of kidnapping and robbery charges after stealing $350,000 in Bitcoin from a teenager during a home invasion. Halem now faces life in prison for what appears to be a 'wrench attack' - a physical crypto theft targeting an individual holder.
Bybit's new fraud prevention system reportedly blocked $300 million worth of risky withdrawals in Q4 2025. Most of the prevented losses came from users voluntarily backing out after receiving real-time warnings, demonstrating a shift in exchange security strategies from post-incident recovery to proactive fraud prevention.
Former LAPD officer Eric Halem was convicted of kidnapping and robbery for stealing $350,000 in bitcoin in 2024. The case highlights ongoing security concerns and criminal activity targeting cryptocurrency holders.
South Korean financial authorities are revising their cryptocurrency custody practices after losing nearly $30 million in seized digital assets over recent months. The move comes following public scrutiny over multiple incidents involving mismanagement of confiscated crypto holdings.
A study reveals that safety-aligned large language models exhibit "Defensive Refusal Bias," refusing legitimate cybersecurity defense tasks 2.72x more often when they contain security-sensitive keywords. The research found particularly high refusal rates for critical defensive operations like system hardening (43.8%) and malware analysis (34.3%), suggesting current AI safety measures rely on semantic similarity rather than understanding intent.
Researchers propose Talaria, a new confidential inference framework that protects client data privacy when using cloud-hosted Large Language Models. The system partitions LLM operations between client-controlled environments and cloud GPUs, reducing token reconstruction attacks from 97.5% to 1.34% accuracy while maintaining model performance.
Researchers introduce OBsmith, an LLM-powered framework that tests JavaScript obfuscators for correctness bugs that can silently alter program functionality. The tool discovered 11 previously unknown bugs that existing JavaScript fuzzers failed to detect, highlighting critical gaps in obfuscation quality assurance.
Researchers developed a new inference-time safety mechanism for code-generating AI models that uses retrieval-augmented generation to identify and fix security vulnerabilities in real-time. The approach leverages Stack Overflow discussions to guide AI code revision without requiring model retraining, improving security while maintaining interpretability.
Researchers have developed a pattern language methodology to systematically identify and modularize crosscutting concerns in agentic AI systems, addressing issues like security, reliability, and cost management that contribute to high AI project failure rates. The approach uses goal models to discover reusable patterns and implements them through aspect-oriented programming in Rust.
Foom Cash suffered a $2.26 million exploit due to a Groth16 verifier misconfiguration. A white hat hacker was able to recover $1.84 million of the stolen funds, limiting the total loss to approximately $420,000.
An on-chain developer has issued a warning about a new wave of deceptive NFT scams targeting XRP Ledger wallet holders. The attacks exploit human error through social engineering tactics, prompting heightened security concerns within the XRP community.
South Korea's National Tax Service is investigating a $4.8 million cryptocurrency theft that occurred after the agency accidentally leaked wallet seed phrases in a photo intended to showcase a crypto seizure. The incident highlights serious security vulnerabilities in government handling of seized digital assets.
Cryptocurrency hack losses dropped dramatically to $26.5 million in February, representing a 98.2% year-over-year decline across 15 incidents according to PeckShield. This significant decrease suggests improved security measures and protocols within the crypto ecosystem.
