Attackers compromised three country-code top-level domains (ccTLDs) and obtained unauthorized HTTPS certificates for several Google domains, Google  said on October 6 . Google's own systems were not breached, but any domain ending in .gh (Ghana), .sl (Sierra Leone) or .as (American Samoa) was put at risk. With such a certificate, an attacker could pose as the real site over an encrypted connection and read the private data sent to it. Chrome blocked the unauthorized certificates for Google's domains through  CRLSets , its way of quickly blocking certificates in emergencies, Google said. The company also worked with the certificate authorities (CAs) that issued the certificates to have them revoked, a step meant to protect people using other browsers and apps. Google did not name the domains.  Certificate Transparency  (CT) logs are the public record of certificates issued by CAs. They show at least 12 certificates issued between September 22 and 27 for Google...

Cybersecurity researchers have disclosed details of a long-running npm supply chain malware campaign that pushes information stealers and remote access trojans (RAT) to compromised hosts. The campaign has been codenamed MALFEX by CloudSEK and Checkmarx . The activity is assessed to be the work of a lone threat actor who appears to have published 12 packages since August 2023, eight of which have been flagged as malicious. The attack is designed to infect Windows systems through three separate pathways - A loader for Overlord , an open-source RAT written in Go that uses Solana transactions to extract the command-and-control (C2) address A chain that installs movinlike, a Node.js stealer targeting Discord, browsers, Telegram, and cryptocurrency wallets, and A downloader The list of identified malicious packages is below - tlxbnhd tldriver mxdriver img-to-native native-runner function-flag (Still live) function-color (Still live) cdn-img-fet...

SonicWall has released hotfixes for four flaws in its SMA1000 appliances, the gateways that give remote workers access to a company's network and applications. The most serious could allow an attacker without a login to send requests through the appliance and reach internal functions. SonicWall rates it 10.0 on the CVSS scale and says it has no evidence that any of the four flaws is being used in attacks. The most serious flaw, tracked as  CVE-2026-102255 , is a server-side request forgery (SSRF) bug in WorkPlace, the portal that SMA1000 users log in to. It exists due to an unintended access path through SonicWall and can be reached before authentication. An attacker who abuses that path could "reach internal functionality and perform unauthorized operations," SonicWall said in its  security advisory , dated October 6, without saying which functions. All four flaws affect SMA1000 models 6210, 7210 and 8200v on these platform-hotfix versions:

A critical vulnerability in LMCache , open-source software that speeds up large language model (LLM) servers such as vLLM, lets an attacker run code on the cache server without logging in, and no fixed version is available. The flaw is in LMCache's  multiprocess mode , where the cache runs as a standalone server that LLM workers reach over the ZeroMQ messaging library. A single network message to that server can run commands as the user the LMCache process runs as. The server can be reached from another machine only when an operator sets it to listen on a routable address, rather than the localhost it uses by default. JFrog disclosed the flaw  on October 7 and assigned it a severity score of 9.8 out of 10, in the critical range, the rating it gives a server bound to a routable address. The vulnerability, tracked as  CVE-2026-105192 , affects LMCache from version 0.3.9, released in October 2025, through 0.5.5, the latest stable release, and is also present in the ...

Cybersecurity researchers are calling attention to a new malware family that has been observed targeting exposed artificial intelligence (AI) and large language model (LLM) infrastructure with an aim to deploy cryptocurrency miners and further expand the scale of the botnet. The financially motivated campaign, dubbed Canto Incognito , has been found to install cryptocurrency miners, including XMRig and Iron, and connects victims to Kryptex, a Russian cryptocurrency mining service. "Compromised hosts are reused to expand the botnet," Lumen Black Lotus Labs said in a report shared with The Hacker News. "Infected servers are turned into scanners and exploit servers, allowing the actor to find and compromise additional vulnerable systems." The malware distributed as part of the campaign has been codenamed PoeLLM owing to what has been described as a "creative" technique that hides the command-and-control (C2) address within a poem the threat actors wr...

The 2026 findings are not just a year-over-year shift. They mark the latest point in a five-year arc where resilience, AI governance, human risk, and board scrutiny are converging inside the systems where work actually happens. For years, the enterprise cybersecurity story has been told as a straight line of escalation: more attacks, more data loss, more pressure, and more urgency. That narrative is still familiar, but comparing the five most recent years of Voice of the CISO research suggests a more useful reading. The CISO role has not simply become harder because every metric is rising at once. It has become harder because the center of risk has shifted and moved closer to the way work now gets done. The latest 2026 findings show signs of progress. Fewer CISOs expect a material cyberattack in the next 12 months, and fewer report material loss of sensitive information than in 2025. But those improvements sit within a longer trend line that is much less settled. Over five years,...

The U.S. Federal Bureau of Investigation (FBI) and Secret Service (USSS) on Tuesday warned that the FortiBleed credential harvesting campaign remains an active threat aimed at internet-facing Fortinet FortiGate firewalls and secure socket layer (SSL) virtual private network (VPN) gateways. "The campaign exploits reused or leaked credentials and legacy SHA-256 password storage, enabling threat actors to harvest and crack authentication data at scale," the agencies said . "Initial findings indicate attackers are continuing to scan internet-exposed Fortinet firewalls using previously obtained compromised credentials." FortiBleed was first documented by SOCRadar in Hudson Rock in June 2026, with the activity targeting thousands of Fortinet firewalls as part of a global campaign. In all, the Russian-speaking operation is estimated to have netted more than 86,644 working device credentials spanning 194 countries as of June 19, 2026. The campaign subsequently pro...

Threat actors have begun to exploit a newly disclosed critical security flaw impacting Atlassian Data Center products that could allow access to sensitive files under certain conditions. The arbitrary file access flaw, tracked as CVE-2026-21589 (CVSS score: 9.3) affects multiple products, including Bitbucket Data Center, Confluence Data Center, Jira Service Management Data Center, Jira Software Data Center, Bamboo Data Center, Crowd Data Center, Crucible, and Fisheye. "This arbitrary file access vulnerability allows an unauthenticated attacker to access specific files within the web application root directory in affected versions," the Australian company said. "Exploitation requires prior knowledge of the target file's exact name and path; this vulnerability does not allow attackers to enumerate or list directory contents. In some configurations, there may be sensitive files present that increase your risk." Atlassian said impacted Atlassian Cloud pro...

If you’re evaluating an agentic pentesting solution right now, you’ve probably heard the same pitch more than once: point it at a target, and it discovers, validates, and exploits attack paths autonomously, the way a real attacker would. That promise is worth taking seriously. It’s also worth pressure testing, and three questions do the heavy lifting.  What can the assessment actually prove?   When is that proof produced? And,  How much of your environment does the proof cover?  Most evaluations stop at the first step. However, it’s at the second and third ones where validation programs are won or lost. One note on where we stand: Picus builds and sells autonomous pentesting . That is exactly why we can be precise about where it ends, because the limits belong to the method, not to any vendor's implementation, and no roadmap can remove them. The problem in four numbers Four numbers from this year explain why the second and third questions now c...

Anthropic on Tuesday said it's expanding a program that allows vetted cybersecurity professionals to test its advanced artificial intelligence (AI) models with reduced safeguards and blocking classifiers, as the company claimed its Project Glasswing initiative uncovered at least 129,000 verified software vulnerabilities between April and July 2026. The company said it also found an additional 5,500 verified software vulnerabilities between April and October 2026 through open-source scanning efforts. "Of these verified vulnerabilities, more than 33,000 have so far been rated as critical- or high-severity," Anthropic said . "This is likely an undercount, as it is based on survey data from only a subset of Glasswing partners. As such, we expect the true impact to be at least five times higher." The updated program, called the Cyber Verification Program (CVP), features three access tiers, allowing organizations and security teams to apply for one that best a...

The Computer Emergency Response Team of Ukraine (CERT-UA) has identified more than 100 compromised websites that have been injected with malicious JavaScript to serve an information-stealing malware called LunexStealer (aka Psychedelic Stealer). The activity, which was observed by the agency in September 2026, has been attributed to a threat cluster dubbed UAC-0277. It did not disclose who the victims of the campaign were or if any systems were successfully compromised as a result of these attacks. "When visiting such a site, users were shown a forged Cloudflare verification page that, under the pretext of confirming the visitor is human, prompted them to execute a command," CERT-UA said in an advisory. "Executing the command caused a malicious MSI package to be downloaded and installed from a remote server (the ClickFix technique)." The attacks also make use of the EtherHiding technique to retrieve the domain name of the resource from which the fake verif...

Cybersecurity researchers have disclosed details of a "human-operated phishing platform" that impersonates advertising products for artificial intelligence (AI) chatbots like Google Gemini, Anthropic Claude, OpenAI ChatGPT, Perplexity, Meta Muse, and Manus. The products, which claim to offer campaign optimization, spend audits, and business-account connections, are designed with one goal in mind: to capture credentials and multi-factor authentication (MFA) codes via spoofed login windows using the browser-in-the-browser ( BitB ) trick. "Each product was built around the same action: Connect," Island researchers Oleg Zaytsev and Ofek Ronen said in a report shared with The Hacker News. "Clicking it opened a browser drawn inside the real browser. The fake address bar displayed trusted origins such as accounts.google.com or an Okta tenant, while the real browser remained on the phishing domain." "Behind the interface, the platform kept every passw...

Linux backdoors targeting telecom and network appliances in South Korea and Taiwan have been disguising their traffic as email services and seemingly legitimate processes to blend in and evade detection. Threat actors are known to name their malicious software after a legitimate operating system component or a process as a defense evasion measure. By borrowing the name of a real binary, it may make it appear less conspicuous among other Windows processes, lend it a false sense of trust, or be overlooked by an analyst during casual inspection. However, the backdoors examined by Rapid7 have been found to go beyond imitating file names by assuming the identities of email security products like SpamSniper and ShareTech that are widely used in enterprise environments in South Korea and Taiwan. According to vendor Jiran Group, SpamSniper is advertised as "Korea's leading email security solution" that defends organizations against spam, malware, and server attacks. T...

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 real attacks. LibreOffice has already  fixed the flaw , which it tracks as CVE-2026-63277, in updates released on October 5. It recommends that users move to version 26.2.5 or 26.8.0. Versions before those are affected. Apache OpenOffice has not fixed the matching flaw, which it tracks as CVE-2026-59265. Every version up to and including its current release, 4.1.16, is affected, and the project  says a fix is expected  in version 4.1.17, which is still being tested. Until then, Apache OpenOffice users can block the attack by turning off Java in the program's settings, or by...

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," the Foundation said in a post. The investigation, it added, was prompted by recent public reports involving Hugging Face and DseWiki where OpenAI's agents turned Artifactory and the German wiki forum into an unsanctioned bulletin board to communicate with each other, while taking steps to chain together online services  to gain access to the internet and cover up evidence of their exploits. To that end, Wikimedia said it identified edits to Wikimedia wikis suspected to be from agents operated by OpenAI. The agents are said to have been testing edits in " sandbox ...

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 ,  traced critical vulnerabilities in Anthropic's MCP source code, downloaded more than 150 million times. This time, we looked at what people actually install: community-published servers across the most popular MCP marketplaces. We found no guardrails and no review. Security is a recommendation, not a policy. A Marketplace With No Bouncer In 2012, Google ran Bouncer, an automated scanner that checked Android apps for malware before they reached users. It wasn't perfect: researchers slipped malware past it . But it existed. MCP marketplaces have no equivalent. Anyone can write a server, push it, and publish it. Even a review wouldn'...
