In case it wasn’t clear: “Should I trust my life savings to Browser Content DOM JavaScript???” Fuck No 1. Browser Environment is Inherently Untrustworthy Exposed Attack Surface: The browser DOM is exposed to numerous potential attack vectors, such as Cross-Site Scripting (XSS), malicious browser extensions, malicious ads, or compromised JavaScript dependencies. Attackers can intercept or alter sensitive information, including private keys or signing processes. Code Executed by the Browser: JavaScript code running in the browser is subject to manipulation. Malicious actors could substitute their own code using techniques like code injection, supply chain attacks, or other vectors that compromise web content. 2. Lack of Hardware and Secure Isolation Critical cryptographic keys must be protected in hardware security modules (HSMs) or other isolated environments such as hardware wallets or trusted execution environments (TEEs). Browsers and the client-side DOM lack this level of hardware isolation. If keys are exposed directly to JavaScript running in the browser, they can be stolen or misused. 3. Vulnerabilities in Tools and Dependencies Multi-signature Bitcoin transactions require interacting with various libraries (e.g., Bitcoin-related crypto libraries). Many JavaScript libraries are open source and potentially trustworthy, but their supply chains are also vulnerable to compromise. It's easy for a malicious actor to introduce backdoors into JavaScript packages or dependencies that are included in your application. Even widely used libraries can be compromised, as seen with high-profile package attacks in the JavaScript ecosystem. 4. Risk of Key Exposure Both multi-signature and single-signature Bitcoin keys are critical to protecting funds. If the private key components used in a multi-signature scheme are exposed, the entire system can be compromised. Handling keys directly in JavaScript (especially if they are stored or processed in the DOM) increases the likelihood of unintentional exposure, cached data leaks, or exfiltration by malicious actors. 5. Long-Term Security A browser-based JavaScript solution for multi-signature Bitcoin management could become vulnerable over time as browsers evolve, libraries change, or new vulnerabilities are discovered. It’s more challenging to guarantee the integrity and long-term security of such a system. 6. Trusted Third Parties Using browser-based tools often involves relying on third-party services to distribute cryptographic libraries or implement parts of the solution. If any of these services are compromised or maliciously altered, they could backdoor the system. Best-Practice Alternatives To manage Bitcoin securely, especially significant amounts of money, you should use tools and approaches specifically designed for high-assurance cryptocurrency security: Hardware Wallets Use hardware wallets like Ledger, Trezor, or Coldcard for managing Bitcoin private keys. These devices isolate private keys and signing operations in tamper-resistant hardware, dramatically reducing the risk of key compromise. Multi-signature setups are supported by many hardware wallets for enhanced security. Dedicated Multi-Signature Wallet Management Services Use trusted services like Casa, Unchained Capital, or Nunchuk that specialize in implementing secure multi-signature wallet setups. They provide tools, workflows, and hardware integrations designed to protect large sums of Bitcoin. Air-Gapped Systems Use air-gapped systems (offline computers) to generate, store, and handle sensitive keys for Bitcoin transactions. Air-gapped systems prevent the private keys from ever touching an internet-connected device, eliminating the risk of remote compromise. Multisig Key Distribution Ensure keys in a multi-signature wallet setup are distributed across multiple independent devices and physical locations. Avoid full key exposure in a single environment. For example, no single system (especially a browser) should have access to enough keys to authorize transactions single-handedly. Open-Source, Auditable Tools Use tools with a strong reputation in the Bitcoin community, such as Bitcoin Core, Electrum (especially in conjunction with hardware wallets), or other open-source, widely reviewed options. Cold Storage (For Long-Term Holdings) Use cold storage techniques, such as paper wallets or offline hardware devices, to protect large-value Bitcoin holdings that do not need frequent transactions. Conclusion Browser-based DOM JavaScript is not an appropriate or secure environment for managing, generating, or signing Bitcoin multi-signature keys. The risks of key compromise due to the inherent vulnerabilities of the browser environment (XSS, dependency attacks, malicious extensions, etc.) are far too high when significant amounts of money are at stake. For high-value Bitcoin protection, invest in hardware wallets, air-gapped setups, or solutions built around professionally implemented multi-signature wallets. These solutions are engineered to minimize attack surface and ensure long-term security for your cryptocurrency holdings.

Keep this note handy, JavaScript enthusiasts: No, developers should avoid using the DOM for any serious cryptography or handling sensitive cryptographic operations. Here's why: Security Risks from DOM Manipulation: The DOM is highly dynamic and can be manipulated by external factors, such as malicious scripts injected by attackers or compromised browser extensions. If sensitive cryptographic operations or information (e.g., keys, passwords) are exposed or handled via the DOM, they become highly vulnerable to interception or manipulation. Man-in-the-Middle and Code Injection Vulnerabilities: JavaScript executes in the user's browser, and the DOM environment is inherently untrustworthy since it can be influenced by other third-party scripts or hostile content injected into a webpage. For example: A malicious script could read sensitive data stored in DOM elements. DOM-based injection attacks could compromise cryptographic routines by altering how the browser executes them. Browser-Level Caching Issues: Aggressive browser caching of JavaScript, APIs, or DOM elements could inadvertently store sensitive cryptographic material, making it possible for attackers to extract data. Developers often cannot guarantee the proper control of caching behavior for DOM-based cryptographic routines or their associated data. Web Crypto API (Preferred Option): The Web Crypto API is the recommended tool for cryptographic operations in JavaScript, as it: Provides low-level cryptographic primitives in a controlled, secure API. Operates outside the DOM, preventing exposure to DOM-based vulnerabilities. Can only be used in secure contexts (HTTPS), reducing the likelihood of interception. However, even with the Web Crypto API, care must be taken to isolate sensitive operations, prevent XSS (cross-site scripting), and avoid handing sensitive data to untrusted parts of an application or other scripts. Best Practices: Minimize Exposure: Ensure cryptographic routines and sensitive data stay out of the DOM. Secure Contexts: Always serve cryptographic operations under an HTTPS environment. Use Web Crypto API: Perform cryptographic operations directly using the Crypto.subtle interface rather than relying on custom implementations or libraries that interact with the DOM. Content Security Policy (CSP): Enforce a strict CSP to prevent unauthorized execution of third-party scripts that could compromise cryptographic functionality. Avoid Direct DOM Handling: Prevent cryptographic keys, passwords, or any sensitive material from being stored or exposed in DOM elements (e.g., <input> fields or hidden form elements). In summary, the DOM is not a secure environment for executing or handling cryptographic routines. Developers should confine cryptographic operations to secure, isolated, and trusted environments, like those provided by the Web Crypto API, to mitigate the inherent vulnerabilities of the client-side execution environment.

"Practically nothing substantial has been presented to the public justifying military intervention in Venezuela. US officials have made half-hearted attempts at blowing the cobwebs off the Reagan-era Cold War boogeyman trope, but the Venezuelan state of Maduro last year spent only 18% of its GDP on public expenditures, making the US (37%) twice as “communist.” It should also be noted that Venezuela’s Communist Party has long been part of the heterogenous US-backed anti-Maduro opposition and is perceived inside the country as a front for the CIA." Summary - **Overview of the Incident**: The abduction of Venezuelan President Nicolas Maduro and his wife, Cilia, by the U.S. is condemned as blatant criminality, with supporters using justifications rooted in the Monroe Doctrine. - **Lack of Justification**: There is no substantial evidence presented for military intervention in Venezuela; U.S. claims of Maduro as a drug kingpin have been dismissed as hypocritical given the presence of actual narco-regimes among U.S.-backed leaders. - **Economic Considerations**: The narrative that the U.S. seeks Venezuelan oil to lower gas prices is critiqued; Maduro’s government has sought negotiations with the U.S. to lift sanctions, but these overtures have been ignored. - **Geopolitical Context**: Realist arguments fail to justify U.S. intervention, as Russia and China show no interest in meddling in Latin America. The focus is on Maduro’s anti-Zionism, which opposes U.S. and Israeli interests in the region. - **Role of Delcy Rodriguez**: Maduro’s successor, Delcy Rodriguez, is scrutinized for her connections to U.S. interests and her ability to navigate sanctions. Her presidency is viewed as pivotal amid fears of further U.S. intervention. - **Public Sentiment**: The approval of Trump’s actions is minimal in both the U.S. and Venezuela, with widespread concern over the potential consequences of another military adventure. - **Historical Context**: The removal of Maduro reflects a long-standing regime change agenda in Venezuela, with both major U.S. political parties implicated in the ongoing conflict. The outcomes of past interventions, like the U.S. coup in Honduras, highlight the potential for negative repercussions Shared via
