Scientists Uncover Hidden Weakness in Quantum Encryption

Quantum key distribution (QKD) is a next generation method for protecting digital communications by drawing on the fundamental behavior of quantum particles. Instead of relying on mathematical complexity alone, QKD allows two users to establish a shared secret key in a way that is inherently resistant to interception, even if the communication channel itself is not private.

When an unauthorized observer attempts to extract information, the quantum states carrying the data are unavoidably altered, creating telltale disturbances that signal a potential security breach.

The real-world performance of QKD systems, however, depends on precise control of the physical link between sender and receiver. One of the most influential factors is pointing error, which occurs when the transmitted beam does not perfectly align with the receiving device.

Critical GNU InetUtils telnetd Flaw Lets Attackers Bypass Login and Gain Root Access

A critical security flaw has been disclosed in the GNU InetUtils telnet daemon (telnetd) that went unnoticed for nearly 11 years.

The vulnerability, tracked as CVE-2026–24061, is rated 9.8 out of 10.0 on the CVSS scoring system. It affects all versions of GNU InetUtils from version 1.9.3 up to and including version 2.7.

“Telnetd in GNU Inetutils through 2.7 allows remote authentication bypass via a ‘-f root’ value for the USER environment variable,” according to a description of the flaw in the NIST National Vulnerability Database (NVD).

Filling the Most Common Gaps in Google Workspace Security

Security teams at agile, fast-growing companies often have the same mandate: secure the business without slowing it down. Most teams inherit a tech stack optimized for breakneck growth, not resilience. In these environments, the security team is the helpdesk, the compliance expert, and the incident response team all rolled into one.

Securing the cloud office in this scenario is all about finding leverage: identifying the strategic control points that drive the most resilience without adding operational overhead.

Google Workspace provides an excellent security foundation, but its native tooling has inherent limitations, and relying on the default configurations can cause headaches. To build a truly resilient program, there are some common-sense first steps teams can take to secure Workspace natively, before intelligently augmenting the platform where its capabilities fall short.

Microsoft shares workaround for Outlook freezes after Windows update

Microsoft shared a temporary workaround for customers experiencing Outlook freezes after installing this month’s Windows security updates.

As explained one week ago, when Microsoft acknowledged the issue, the bug causes the classic Outlook desktop client to hang for users with POP email accounts who have deployed the KB5074109 security update on Windows 11 25H2 and 24H2 systems.

Other symptoms include the inability to reopen Outlook without ending the process via Task Manager or restarting the device, Outlook redownloading emails, and emails not appearing in the Sent Items folder even though they were sent.

Ben & Marc: Why Everything Is About to Get 10x Bigger

Three Flaws in Anthropic MCP Git Server Enable File Access and Code Execution

A set of three security vulnerabilities has been disclosed in mcp-server-git, the official Git Model Context Protocol (MCP) server maintained by Anthropic, that could be exploited to read or delete arbitrary files and execute code under certain conditions.

“These flaws can be exploited through prompt injection, meaning an attacker who can influence what an AI assistant reads (a malicious README, a poisoned issue description, a compromised webpage) can weaponize these vulnerabilities without any direct access to the victim’s system,” Cyata researcher Yarden Porat said in a report shared with The Hacker News.

Mcp-server-git is a Python package and an MCP server that provides a set of built-in tools to read, search, and manipulate Git repositories programmatically via large language models (LLMs).

Microsoft releases OOB Windows updates to fix shutdown, Cloud PC bugs

Microsoft has released multiple emergency, out-of-band updates for Windows 10, Windows 11, and Windows Server to fix two issues caused by the January Patch Tuesday updates.

The first issue impacts Windows 11, Windows 10, and Windows Server and blocks access to Microsoft 365 Cloud PC sessions. After installing the January 2026 security updates, some users may encounter credential prompt failures in remote connection applications.

“After installing the January 2026 Windows security update (the Originating KBs listed above), credential prompt failures might occur in some remote connection applications,” explained Microsoft.
