### Who is affected? This advisory only applies to developers who use MetaMask SDK in the browser and who, on Sept 8th 2025 between 13:00–15:30 UTC, performed one of the following actions and then deployed their application: - Installed MetaMask SDK into a project with a lockfile for the first time - Installed MetaMask SDK in a project without a lockfile - Updated a lockfile to pull in `debug@4.4.2` (e.g., via `npm update` or `yarn upgrade`) ### What happened? On Sept 8th, 2025 (13:00–15:30 UTC), a malicious version of the `debug` package (v4.4.2) was published to npm. The injected code attempts to interfere with dApp-to-wallet communication when executed in a browser context. While MetaMask SDK itself was not directly impacted, projects installing the SDK during this window may have inadvertently pulled in the malicious version of `debug`. ### Mitigation - If your application was rebuilt and redeployed after Sept 8th, 2025, 15:30 UTC, the malicious version of debug should no longe...

Mattermost versions 10.10.x <= 10.10.1 fail to properly sanitize user data during shared channel membership synchronization, which allows malicious or compromised remote clusters to access sensitive user information via unsanitized user objects. This vulnerability affects Mattermost Server instances with shared channels enabled.

Attacks that target users in their web browsers have seen an unprecedented rise in recent years. In this article, we’ll explore what a “browser-based attack” is, and why they’re proving to be so effective.  What is a browser-based attack? First, it’s important to establish what a browser-based attack is. In most scenarios, attackers don’t think of themselves as attacking your web browser.

In a world where threats are persistent, the modern CISO’s real job isn't just to secure technology—it's to preserve institutional trust and ensure business continuity. This week, we saw a clear pattern: adversaries are targeting the complex relationships that hold businesses together, from supply chains to strategic partnerships. With new regulations and the rise of AI-driven attacks, the

A new artificial intelligence (AI)-powered penetration testing tool linked to a China-based company has attracted nearly 11,000 downloads on the Python Package Index (PyPI) repository, raising concerns that it could be repurposed by cybercriminals for malicious purposes. Dubbed Villager, the framework is assessed to be the work of Cyberspike, which has positioned the tools as a red teaming

A list of topics we covered in the week of September 8 to September 14 of 2025

Chinese-speaking users are the target of a search engine optimization (SEO) poisoning campaign that uses fake software sites to distribute malware. "The attackers manipulated search rankings with SEO plugins and registered lookalike domains that closely mimicked legitimate software sites," Fortinet FortiGuard Labs researcher Pei Han Liao said. "By using convincing language and small character

Recently, we’ve shared a lot about post-quantum cryptography, the great work we’re doing to make it available to you through our products, and the importance of preparing for a future with quantum computers powerful enough to break classic RSA-based cryptography. You may have heard about “Q-day,” the day when a cryptographically relevant quantum computer (CRQC) is available to break public-key encryption–the underpinning of our digital world today. If you missed it, this risk is real, and proactive organizations are already preparing for it. Q-day is predicted to occur between 2029 a

A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in the Hugging Face Transformers library, specifically within the `normalize_numbers()` method of the `EnglishNormalizer` class. This vulnerability affects versions up to 4.52.4 and is fixed in version 4.53.0. The issue arises from the method's handling of numeric strings, which can be exploited using crafted input strings containing long sequences of digits, leading to excessive CPU consumption. This vulnerability impacts text-to-speech and number normalization tasks, potentially causing service disruption, resource exhaustion, and API vulnerabilities.
