A malicious spreadsheet can make LibreOffice and Apache OpenOffice run an attacker's code as soon as the file is opened, security researchers have shown. There is no warning first, of the kind either program shows before it runs a macro.
The attack works only when the program's Java support is enabled. So far, it has only been shown as a proof of concept, and there are no reports of its use in
The Wikimedia Foundation, which hosts Wikipedia, has confirmed that it has discovered activity by rogue OpenAI agents on its platforms, including unsuccessful efforts to compromise Etherpad, a public note-taking tool, and edit Wikipedia pages.
"The unauthorized bot activities included edits to our wikis, some unsuccessful attempts to exploit a public note-taking tool we host, and heavy traffic,
In 2024, MCP (Model Context Protocol) set out to become the USB-C of AI: one standard for connecting models, agents, and IDEs to tools and data. The protocol delivered. Thousands of developers built servers, and enterprises plugged them into agent workflows.
The ecosystem around it fell short. Earlier this year, our team at OX Security,Β traced critical vulnerabilities in Anthropic's MCP
Google has stopped accepting product vulnerability reports through its bug bounty program for its open-source software.
The change, in effect since October 1, means researchers can no longer submit security flaws in the code of projects such as Go, Angular, and Protocol Buffers there for a reward. Reports about supply chain compromises are still accepted, and reports filed before October 1 are
A critical flaw in 8 Atlassian Data Center products, which customers host themselves, allows an attacker with no login access to read specific files in each product's web application root directory.
The attacker must already know a file's exact name and path and cannot list what the directory holds. AtlassianΒ disclosed the flaw, CVE-2026-21589, on October 5, rated it 9.3 out of 10, and
The U.S. Federal Bureau of Investigation (FBI) has removed an Accenture contractor for their alleged role in a ShinyHunters-breach that led to the theft of personal details of thousands of bureau employees.
That's according to a report from Reuters, citing two sources familiar with the matter.
"To date, our review has determined that the incident occurred as the result of a security failure β
Unauthorized parties have gained access to the names, addresses, and personal identification numbers of about 8.8 million people, living and dead, in Denmark's national population register, the country's digitalization ministryΒ said on October 5.
They used a private Danish company's lawful right to look up records in the Central Person Register (CPR). The ministry has told people never to
A new type of ClickFix attack is using compromised websites to trick users into executing a malicious payload cached in a web browser's cache.
"Instead of downloading and executing remote payloads like the typical attack pattern, in this attack, the websites pre-fetch a script payload into the browser cache disguised as a PNG file," the Microsoft Threat Intelligence team said in a post on X.
Microsoft has released out-of-band security updates to address a high-severity flaw in Microsoft Exchange Server that could allow an attacker to escalate privileges under certain conditions.
The vulnerability, tracked as CVE-2026-96940, is rated 8.8 on the CVSS scoring system.
"Weak authorization in Microsoft Exchange Server allows an authenticated attacker to elevate privileges over a
A blank field. A public repo. One reply to an email. A box left exposed. None of this sounds dramatic, which is partly the problem. This weekβs threats keep finding leverage in small things that were easy to overlook.
There are actively exploited bugs in the mix, cleaner intrusion paths, smarter automation, and a long patch list waiting behind them. Some attacks are getting more capable. Others
Every modern enterprise depends on credentials. This is how humans, systems, and now AI, all connect to data, services, and each other securely. GitGuardian helps secure that credential layer through three connected capabilities: Detect, Remediate, and Prevent. The journey starts with detection, because organizations first need to understand what credentials exist, where they live, and what they
Threat actors have been observed attempting to exploit a now-patched critical security flaw impacting the Realtek Jungle software development kit (SDK) to deploy a botnet malware called Cling.
"Cling is notable not because it introduces a new propagation technique, but because it repurposes ordinary STUN behavior into a practical command-and-control channel," Nozomi Networks said in a report
Apple has announced that it's taking steps to tighten controls around a macOS setting called Full Disk Access (FDA) due to security risks posed by artificial intelligence (AI) agents.
"Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systemsβincluding files, mail, messages, and even browsing history β without users' full knowledge
A critical security flaw impacting Rejetto HTTP File Server (HFS) is witnessing active exploitation attempts, according to VulnCheck.
The vulnerability in question is CVE-2026-61500 (CVSS score: 9.3), a case of session forgery stemming from the use of a weak pseudo-random number generator (PRNG) that can lead to a predictable key, which an attacker can then use to gain unauthorized access and
Citrix has released security updates for a high-severity security flaw in NetScaler ADC and NetScaler Gateway that has been exploited as part of targeted zero-day attacks.
The vulnerability, tracked as CVE-2026-88779, carries a CVSS score of 8.7 out of 10.0.
"CVE-2026-88779 is a memory overflow vulnerability in Citrix NetScaler ADC and Citrix NetScaler Gateway that can lead to
A suspected member of the ShinyHunters digital extortion group, who goes by the online alias "Rey," has been allegedly detained by authorities in Jordan, Reuters reported, citing three people familiar with the matter.

A new China-nexus cyber espionage group known as TA419 has been attributed to multiple credential phishing campaigns targeting artificial intelligence (AI) experts working for U.S. think tanks, universities, and legal sector organizations.
The campaigns have impersonated prominent economists and AI policymakers, as well as a prominent Anthropic employee, to single out an AI policy expert at a
The suspected China-linked threat actor known as Warlock is still continuing to weaponize Microsoft SharePoint vulnerabilities, likely both old and new, in attacks targeting organizations in Portuguese- and Spanish-speaking countries.
The activity, observed by the Symantec and Carbon Black Threat Hunter Team, has hit critical infrastructure, government, and education organizations.
