Coverage of #security spans 862 indexed articles, with 378 published in the last 30 days. Recent discussion leans bearish, at 49.7% negative sentiment versus 46.8% bullish, though sentiment has remained stable over the past month. Top sources include arXiv's computer science and AI research, along with cryptocurrency-focused outlets like Crypto Briefing and Blockonomi. The tag frequently intersects with #ai, #bitcoin, and geopolitical concerns, with Anthropic and Claude among the most-discussed entities. Bitcoin and Ethereum dominate ticker mentions in this coverage area. Explore the articles below to understand the full scope of recent #security developments.
A new study reveals Bitcoin's network resilience to submarine cable failures, showing it can survive 72-92% of global cable outages during random failures. However, targeted attacks on high-betweenness cables could fragment the network with only 20% damage, and hosting provider failures pose significant risks with just 5% capacity loss.
Trump's AI czar David Sacks warns of escalating conflict scenarios involving Iran and calls for U.S. withdrawal from current military engagements. He specifically mentions Iran's potential 'dead man's switch' capability that could threaten Gulf state habitability.
Crypto ATM losses increased by 33% in 2025, with AI technology being used to enhance and superpower scamming operations. CertiK identifies crypto ATMs as the most accessible extraction method for scammers to convert stolen funds.
Ledger's security team discovered a critical vulnerability in MediaTek's secure boot chain that allows attackers to steal cryptocurrency seed phrases from Android devices in just 45 seconds. MediaTek has since patched the security flaw that could have compromised sensitive crypto wallet information on affected Android devices.
Researchers have developed a risk assessment framework for open-source Model Context Protocol (MCP) servers, revealing significant security vulnerabilities through static code analysis. The study found many MCP servers contain exploitable weaknesses that compromise confidentiality, integrity, and availability, highlighting the need for secure-by-design development as these tools become widely adopted for LLM agents.
CoinFello has developed a new OpenClaw skill that enables AI agents to perform cryptocurrency transactions through MetaMask without requiring access to private keys. This innovation addresses a critical security vulnerability in AI-crypto integrations.
OpenAI has developed an agent runtime that transforms their Responses API from a simple model interface into a full computing environment. The system uses shell tools and hosted containers to enable secure, scalable AI agents that can manage files, execute tools, and maintain state.
BIP-360 proposes changes to Bitcoin's quantum defense strategy, improving resistance against quantum computing threats. However, the proposal falls short of providing complete post-quantum security for the Bitcoin network.
Trust Wallet has launched automatic Address Poisoning Protection to combat address poisoning attacks, which Cyvers estimates occur over one million times per day on Ethereum. This security feature aims to prevent users from accidentally sending funds to malicious addresses that mimic legitimate transaction histories.
Bitcoin's circulating supply reached 20 million coins on March 9, marking 95% of the total 21 million BTC supply now mined. This milestone leaves fewer than 1 million coins remaining to be mined and raises concerns about Bitcoin's long-term security model as mining rewards diminish.
Mastercard and Google have partnered to develop Verifiable Intent, a cryptographic solution that creates tamper-resistant records of user authorizations when AI agents make purchases on their behalf. This technology aims to build trust and security in AI-powered shopping experiences by ensuring transparent verification of user consent.
Researchers propose the Disentangled Safety Hypothesis (DSH) revealing that AI safety mechanisms in large language models operate on two separate axes - recognition ('knowing') and execution ('acting'). They demonstrate how this separation can be exploited through the Refusal Erasure Attack to bypass safety controls while comparing architectural differences between Llama3.1 and Qwen2.5.
Bitcoin developer Hunter Beast has proposed the Hourglass V2 solution to address the risk of Satoshi Nakamoto's Bitcoin holdings being stolen through quantum computing attacks. The proposal aims to mitigate potential sell pressure on Bitcoin markets if these early coins are compromised and liquidated.
Researcher Justin Bons has raised concerns that quantum computing technology could potentially break the privacy features of privacy-focused cryptocurrencies Zcash and Monero in the future. This highlights a potential long-term vulnerability in current cryptographic protocols used by these privacy coins.
A CoinShares report reveals that only 10,230 Bitcoin out of nearly 20 million in circulation are currently vulnerable to quantum computing attacks. This finding comes as quantum computing facilities continue to expand, raising questions about Bitcoin's long-term security against quantum threats.
The article discusses three key developments in the intersection of AI and cryptocurrency, highlighting both problematic applications like criminal use cases and positive developments such as AI-powered smart contract auditing. These developments signal the emergence of an 'agentic frontier' where AI agents operate autonomously within crypto ecosystems.
A new study reveals that 95% of Bitcoin nodes could be vulnerable to attacks on underwater internet cables. This research highlights how Bitcoin's decentralization is still dependent on vulnerable physical internet infrastructure.
The FBI has reportedly arrested John Daghita in the Caribbean, who is accused of stealing $46 million in cryptocurrency from the US Marshals Service. The suspect was first identified by blockchain investigator ZachXBT.
The FBI arrested John Daghita, son of a custody company CEO, in connection with an alleged $46 million cryptocurrency theft. FBI Director Kash Patel shared images of the arrest and seized items including cash, thumb drives, and hardware wallet-like devices.
John Daghita, son of a federal contractor, has been arrested and charged with stealing $46 million from the US government's cryptocurrency stockpile. The crime was initially exposed by blockchain investigator ZachXBT in January before official charges were filed.
The FBI has arrested a suspect in Saint Martin in connection with an alleged $46 million theft from US Marshals cryptocurrency holdings. The suspect was previously linked by blockchain investigator ZachXBT to the online persona 'Lick,' who allegedly accessed wallets containing crypto seized from the 2016 Bitfinex hack.
John Daghita, son of a U.S. government contractor, was arrested for allegedly stealing over $46 million in cryptocurrency that had been seized by the U.S. government. This case highlights significant security vulnerabilities in how government agencies handle confiscated digital assets.
The son of a US government contractor was arrested for allegedly stealing $46 million in cryptocurrency from the US Marshals Service. This incident exposes significant vulnerabilities in how government agencies manage and secure digital assets.
