New research has found that it is possible for threat actors to abuse a legitimate feature in GitHub Codespaces to deliver malware to victim systems. GitHub Codespaces  is a cloud-based configurable development environment that allows users to debug, maintain, and commit changes to a given codebase from a web browser or via an integration in Visual Studio Code. It also comes with a port forwarding feature that makes it possible to access a web application that's running on a particular port within the codespace directly from the browser on a local machine for testing and debugging purposes. "You can also forward a port manually, label forwarded ports, share forwarded ports with members of your organization, share forwarded ports publicly, and add forwarded ports to the codespace configuration," GitHub  explains  in its documentation. It's  important  to note here that any forwarded port that's made public will also permit any party with knowledge of the URL

A new attack vector targeting the Visual Studio Code extensions marketplace could be leveraged to upload rogue extensions masquerading as their legitimate counterparts with the goal of mounting supply chain attacks. The technique "could act as an entry point for an attack on many organizations," Aqua security researcher Ilay Goldman  said  in a report published last week. VS Code extensions, curated via a  marketplace  made available by Microsoft, allow developers to add programming languages, debuggers, and tools to the VS Code source-code editor to augment their workflows.  "All extensions run with the privileges of the user that has opened the VS Code without any sandbox," Goldman said, explaining the potential risks of using VS Code extensions. "This means that the extension can install any program on your computer including ransomwares, wipers, and more." To that end, Aqua found that not only is it possible for a threat actor to impersonate a po

Streamline your zero-trust access journey with three simple steps for high-risk, remote, and hybrid users.

Severe security flaws uncovered in popular Visual Studio Code extensions could enable attackers to compromise local machines as well as build and deployment systems through a developer's integrated development environment (IDE). The vulnerable extensions could be exploited to run arbitrary code on a developer's system remotely, in what could ultimately pave the way for supply chain attacks. Some of the extensions in question are "LaTeX Workshop," "Rainbow Fart," "Open in Default Browser," and "Instant Markdown," all of which have cumulatively racked up about two million installations between them. "Developer machines usually hold significant credentials, allowing them (directly or indirectly) to interact with many parts of the product," researchers from open-source security platform Snyk  said  in a deep-dive published on May 26. "Leaking a developer's private key can allow a malicious stakeholder to clone important
