first_img Claude Code VS Code extension implanted with SSH backdoor

On October 30, security researcher Paul McCarty (6mile) posted on the OpenSource Malware blog that Anthropic's Claude Code VS Code extension was tampered with that day, and a malicious version 2.1.313 was published to the Open VSX registry. The extension is identified as anthropic.claude-code@2.1.313, and a 66-line loader was inserted before the normal extension code in the main JavaScript package. The researchers stated that currently, only the analyzed Open VSX version has been confirmed as a malicious sample, and a threat report has been submitted for the same version in the Microsoft VS Code marketplace out of caution.The article states that the unpacked extension and bundled binaries are consistent with the normal version, with differences only in extension.js. The extension loads this file after VS Code starts and when the Webview opens, triggering without the user needing to initiate a Claude conversation. The loader writes an attacker key labeled svc-telemetry to the user's SSH configuration, attempts to enable local SSH services, establishes a reverse tunnel to 134.209.82.225, and sets persistence on macOS, Linux, and Windows, then sends host reconnaissance information to port 8099 at that address via unencrypted HTTP. No additional executable files or scripts are downloaded during the injection phase.The researchers stated that the owner of the affected Open VSX extension is Anthropic employee Igor Kofman, and it is currently unclear whether his account or another release link was exploited; Dean Hardcastle informed him at the time of the incident. The article clarifies that the source of the analyzed directory has not been established, and the related findings cannot independently prove that Anthropic's official marketplace or distribution infrastructure has been compromised; the identity of the attacker and the ownership of the infrastructure have also not been verified. The text suggests searching for related file paths, key annotations, and startup items, blocking ports 22 and 8099 of 134.209.82.225, and rotating credentials accessible by affected accounts on a clean system.

first_img Stablecoin payment startup Velocity completed a $10 million Series A extension round financing with a valuation of $200 million, with participation from Visa Ventures and others

According to CoinDesk, stablecoin payment startup Velocity announced that it has completed a total of $48 million in Series A funding, with a valuation of $200 million. This round includes an additional $10 million investment from Visa Ventures, Circle Ventures, Haun Ventures, Ripple, Translink Capital, and Mirana Ventures. Previously, the company completed $38 million in Series A funding in July.Velocity is headquartered in London, and its platform aims to help payment companies and banks use stablecoins for settlement, liquidity, and fund management without replacing existing systems. CEO Eric Queathem, who previously worked at Worldpay, which handled over $2 trillion in payment volume annually, believes that for the past 15 years, capital has been concentrated on improving the consumer front-end experience, while the back-end settlement layer has been neglected.Visa's involvement is particularly noteworthy, as Velocity does not believe that stablecoins will replace bank cards, but rather expects blockchain digital assets to take on more funding and settlement functions beneath the existing payment experience. Queathem anticipates that in the next five years, global enterprises will hold on-chain assets, and the partial on-chain funding of enterprises will create a greater infrastructure demand than merely stablecoin deposits and withdrawals.

first_img Socket exposes 77 malicious wallet extensions for Firefox, 40 confirmed to steal mnemonic phrases

According to a report by Decrypt, security company Socket released research results linking 77 Firefox extensions to what it calls a "wallet theft factory," with 40 confirmed to have malicious behavior.These extensions disguise themselves as Web3 products like OKX, Rabby Wallet, and TronLink, tricking users into importing wallets through fake wallet interfaces or using modified real wallet code to steal mnemonic phrases and private keys as users input them. Mozilla's signature records show that this activity lasted from March 9 to August 3, and multiple extensions were still online at the time of Socket's report.About half of the extensions displayed realistic wallet interfaces and prompted users to import existing wallets, thereby intercepting the inputted mnemonic phrases or private keys; another 13 were modified versions of Rabby that sent account data stored in wallets to external servers while functioning normally; and 5 specifically collected saved credentials and clipboard content.Additionally, 37 extensions disguised themselves as password generators, dark mode toggles, VPNs, currency converters, and note-taking tools, but actually ran sports score applications sharing the same hardcoded credentials. Nine confirmed malicious extensions were initially released as score applications for sports like football and basketball, with subsequent updates replacing them with wallet theft code.Socket named this activity the "wallet theft factory," but cautioned that it has not confirmed whether all extensions are controlled by the same operator. The Socket team stated that any user who has entered mnemonic phrases or private keys into these extensions should consider it a "permanent leak" and immediately transfer funds to a new wallet, as uninstalling the extensions cannot undo the mnemonic phrases sent elsewhere.

first_img OpenAI resets all ChatGPT Work and Codex user usage, with an expected extension of about 18% after optimization

On July 29, Tibo, the product lead for OpenAI Codex, announced on X that all usage limits for ChatGPT Work and Codex users have been reset, and released a statement regarding the issue of rapid consumption of GPT-5.6 Sol usage.In the previous weeks, a large number of users reported that the consumption speed of Codex limits exceeded expectations. OpenAI emphasized that it has not reduced the usage quotas of any subscription plans. After investigation, several reasons were found: Sol is more inclined to work for longer periods, execute more tool calls, and coordinate complex workflows than previous models; it consumes more tokens at the same reasoning level; programmatic tool calls (code mode) allow Sol to execute tool calls in parallel, resulting in more responses and higher usage per round; the distribution of impact is extremely uneven, with median user efficiency being acceptable, but heavy users handling complex tasks consuming far more than expected.OpenAI stated that multiple improvements have been completed, and it is expected that usage endurance will be extended by about 18% in typical usage scenarios. Tomorrow, the five-hour limit that was paused during the investigation will be restored. OpenAI acknowledged that "capabilities and efficiency do not always improve synchronously, and some issues only become apparent after large-scale real-world use; we should have realized this earlier."
