Google Cloud VMs on AMD Turin chips need a guest OS patch and a stop-and-start to protect against three CPU side-channel flaws, Google said this week. The company has already applied mitigations against attacks between VMs, and between VMs and the host. Inside a VM, the flaws may let an attacker with code on the same processor core infer data from other processes or the kernel. The affected machine series are C4D, N4D, H4D, Z4D,, and G4, including bare-metal instances of C4D and Z4D. Turin is the code name for fifth-generation AMD EPYC processors. All three flaws are Transient Scheduler Attacks (TSA). Two of them, TSA-SQ (CVE-2024-36350) and TSA-L1 (CVE-2024-36357), were first disclosed on July 8, 2025, for earlier EPYC processors. AMD now says its Zen 5 processors, which include Turin, are "impacted differently from previously characterized AMD processors." The third flaw, CVE-2026-0004, is new. It may let an attacker who can run code on a system infer data in the p...

Security teams have more alerts, logs, and monitoring tools than ever. Yet when an attack happens, one simple question can still take too long to answer: Who or what is behind this activity, and what can they access? A suspicious login might belong to an employee. An unusual API call could come from a machine account. Or an AI agent might be accessing sensitive systems using permissions nobody has reviewed recently. Your SIEM or EDR may catch the activity. But without knowing who owns that identity, what permissions it has, and which systems it can reach, your SOC is missing a critical part of the story. And that missing context can turn a manageable incident into a much bigger problem. Join this expert-led webinar to learn how real-time identity context can help your SOC investigate threats faster, understand what's at risk, and respond with confidence. The Blind Spot Between Identity and Security Operations Here's the problem. Identity and access management (...

N-able on Thursday said it's investigating a new public disclosure containing claims of additional vulnerabilities in on-premise versions of N-central running version 2026.4.1 HF2. "Based on our initial review, the server issue described depends on a non-default configuration in which the Legacy API is turned on and exposed to the public internet," N-able said in a new advisory. "Legacy API is turned off by default in the product and is not recommended." The company is urging customers to disable Legacy API immediately, if not already. It also noted that Hosted environments are not affected by this issue. The incident impacts the following services - N-central On-premise (Americas) N-central On-premise (APAC) N-central On-premise (Europe) The development comes days after N-able released 2026.4.1.26 to address a number of security flaws disclosed by independent security researcher Sean Bales earlier this week. The vulnerabilities are collec...

Since mid-August 2026, a phishing operation has been stealing live Google sessions from corporate users. Every check defenders normally lean on to judge a link came back clean, and the operator designed it that way on purpose. The Threat Research team at Material Security spotted the campaign and has since taken down hundreds of attacker domains in an effort the team calls Operation CloudFire. Here’s what the researchers found. The lure: Google Calendar invites The messages show up as Google Calendar invites. Some arrive by BCC, and many come from an organization the recipient has already traded email with. The pretexts are deliberately boring: voicemail notifications, RFP and RFI requests, court summonses, and missed payment notices. Nothing about them stands out in a busy inbox. Most of the links point to Google itself. The usual pattern runs through Google’s own /url redirector, with the real destination tucked into a query parameter. Other waves used share.google and Driv...

PTC has released patches for a new critical vulnerability impacting Windchill and FlexPLM software that, if successfully exploited, could result in remote code execution. The security flaw, tracked as CVE-2026-126325 , carries a CVSS v4 score of 9.2 out of a maximum of 10.0. It has been described as a case of improper input validation and deserialization of untrusted data that could result in remote code execution via crafted requests. "A critical remote code execution (RCE) vulnerability has been reported in PTC Windchill and PTC FlexPLM," according to a description of the flaw on CVE.org. "The vulnerability may be exploited through the deserialization of untrusted data." The CVE record lists the following versions as affected - PTC Windchill: 11.0 M030, 11.1 M020, 11.2.1.0, 12.0.2.0, 12.1.2.0, 13.0.2.0, 13.1.0.0, 13.1.1.0, 13.1.2.0, 13.1.3.0, 13.1.4.0 PTC FlexPLM: 11.0 M030, 11.1 M020, 11.2.1.0, 12.0.2.0, 12.1.2.0, 13.0.2.0, 13.1.0.0, 13.1.1.0, ...

A critical flaw in MongoDB Server allows an unauthenticated attacker to send two requests that trigger a crash on the database server. The crash occurs only if that server is later chosen to take over as the main server while it still lacks some recent changes. MongoDB, the company that makes the database, released fixed versions earlier this week. The affected servers are members of a replica set, a group of MongoDB servers that keep copies of the same data. One member, the primary, serves as the main server and handles all new writes, while the others replicate them. If the primary becomes unavailable, the other members hold an election to pick a new primary. Researchers at Datadog Security Labs reproduced the crash in a lab and published their findings yesterday. On vulnerable versions, turning on authentication does not stop the two requests. An attacker cannot make the targeted member fall behind or win an election, or see when either happens, the researchers said. The fl...

A flaw fixed in Node.js this week lets unauthenticated clients crash servers that use the runtime's built-in HTTP/2 support on the 24.x and 26.x release lines. A second HTTP/2 flaw can cause a server to send a client pieces of its memory, including responses intended for other connections. Fixed versions were released for all three supported lines: 22.23.5, 24.22.3, and 26.13.1. The crash flaw, CVE-2026-123863 , needs only a default HTTP/2 server that replies before the request body has fully arrived. The Node.js project calls that behavior typical. The crash works over both TLS and cleartext connections. The memory flaw, CVE-2026-123866, affects all three lines. From 24.22.0 and 26.9.0 onward, a client alone can trigger it. On 22.x and older 24.x and 26.x builds, it can still be triggered when the server itself closes a stream partway through a response, for example after an idle timeout. A separate flaw in Node.js HTTPS servers, CVE-2026-123864, can allow an unauthenti...

Starting Tuesday, an attacker used stolen credentials for 4,837 GitHub accounts to plant a secret stealer in repositories those accounts could write to, according to Aikido Security, a security software company. The stealer is built to take the secrets and cloud credentials that a repository's CI workflows can reach. It ran in at least 1,806 repositories, where the attacker has likely collected those credentials, the company says. Each attack started with a pull request titled docs: dependency audit notes, opened from a branch named wfx-docs to test whether the account could write to the repository. These test pull requests were opened in 61,764 repositories, and the stealer followed in some of them. In a separate analysis , researchers at SafeDep, which sells software supply chain security tools, counted 8,093 repositories that received malicious commits between 12:46 UTC on Tuesday and 04:36 UTC today. That count covers every repository that received malicious commits, no...

A critical flaw in Apache HTTP Server's HTTP/2 module, mod_http2 , can let a remote attacker run code on the server. Tracked as CVE-2026-119618 , it affects versions 2.4.55 through 2.4.70 and is fixed in version 2.4.71, released yesterday. Only servers with HTTP/2 enabled are affected, according to Red Hat, which ships the server as part of Red Hat Enterprise Linux. An attacker who can reach the server needs no authentication to exploit the flaw and could take full control of the server process, the Linux vendor says. It rates the flaw 9.8 out of 10 on the CVSS scale. The vendor's assessment, published yesterday, also says "public research has demonstrated a reliable exploit" against a server in its default configuration with mod_http2 enabled. It does not name or link that research. Security company Wiz said later that day that no exploit was available and that no exploitation in the wild had been reported. HTTP/2 runs only where the Protocols directive turn...

ConnectWise has taken the precautionary step of disabling five third-party extensions in partner environments following reports of unauthorized access . In an advisory posted on its site, the company said there is no evidence that the incident involves a compromise of its infrastructure or a vulnerability in the ScreenConnect software. "Our initial assessment suggests the activity may involve a threat actor's abuse of independent third-party extensions installed in partner environments," it said . "We are continuing to validate this assessment. The initial access method and full scope remain under investigation." ConnectWise has identified about 400 partner environments with at least one of the third-party extensions installed. It also emphasized that the presence of the extensions alone does not indicate or establish compromise. While these extensions provide an API capable of executing remote commands, access to that API is secured by a passphrase c...

Zoom has released software updates to address two security flaws impacting Zoom Workplace for Windows, including a critical bug that could result in privilege escalation on affected systems. The vulnerabilities are listed below - CVE-2026-108186 (CVSS score: 9.6) - An improper input validation vulnerability that could allow an unauthenticated user to conduct an escalation of privilege via network access. CVE-2026-108187 (CVSS score: 8.1) - An origin validation vulnerability that could allow an unauthenticated user to conduct an escalation of privilege via network access. Successful exploitation of either of the shortcomings could permit remote attackers to escalate privileges without requiring any special permissions or access. While CVE-2026-108187 affects Zoom Workplace for Windows before version 7.1.5, CVE-2026-108186 impacts versions starting from 7.1.0 and before 7.1.8. Earlier this July, the popular videoconferencing platform shipped fixes for another improper ...

Cybersecurity researchers have disclosed details of a campaign in which an emerging agentic penetration testing platform called AntiFox has been used to steal Amazon Web Services (AWS) credentials and pivot laterally into compromised environments. "In several recently observed intrusions, Alibaba Cloud systems hosting AntiFox interfaces were associated with confirmed malicious actions against internet-facing web services and associated AWS environments," Arctic Wolf Labs said in a report shared with The Hacker News. The activity has been observed chaining together web exploitation and web shell deployment to facilitate configuration discovery, credential validation, cloud-service enumeration, secret access, and storage operations. AntiFox, available for download from GitHub, has been described as an artificial intelligence (AI)-driven autonomous penetration testing platform that's built atop the "solid foundation" of ARTEX . As of writing, the project...

Threat actors have been observed targeting Qlik Sense servers to unsuccessfully deliver PowerShell reverse shell commands against multiple environments in October 2026. Cynet's CyOps and Research teams said they identified the suspicious activity in October 2026 against several E.U.-based customers within a narrow window of just over three minutes. The activity has been found to share some level of overlap with a November 2023 campaign documented by Arctic Wolf in which threat actors linked to the CACTUS ransomware operation likely weaponized then-newly-disclosed flaws in Qlik Sense to obtain initial access to target environments. The vulnerabilities in question, which were patched by Qlik Sense in August and September 2023, impact Qlik Sense Enterprise for Windows -

Of the 37,571 Grok-built apps that security company Claroc found online, 35,578 were open to anyone without a sign-in, the researchers said yesterday. They included 24 apps built by staff at the social network X and at SpaceXSI, the company that makes the Grok AI assistant. Most of the open apps were games, landing pages, and calculators, but about 1 in 10 contained internal business or personal data. The staff apps included a confidential onboarding plan for a new sales hire, a sales territory map of 594 accounts, and an X advertising proposal to a U.S. federal agency marked confidential. SpaceXSI, formerly known as xAI, has since taken down all 24 staff apps but not other users' apps, the researchers said. Besides those staff apps, the open apps contained internal data from 30 other organizations the researchers could identify, across fields ranging from construction and energy to healthcare and defense. Of those, 26 have more than 1,000 employees, and 6 are Fortune 500 co...

We tell customers three things about securing AI agents: they need their own identities, access that fits the job they’re given, and traceability that’s separate from any human’s. That was true for us at Token as well. Then, we built an agent that broke all three by default. This helped us think through how such agents should be defended. When a browser agent acts inside a user’s authenticated session, the application may see the user but not the agent, the delegation, or the task’s intended scope. By creating an agent that breaks all the security rules, Token learned how companies should be using identity to gain control, especially as agent use scales. Standards are coming, but there are steps security teams can take today. The agent we would have flagged The agent we created is named Rehearsal . Its job is to answer questions inside the Token platform by doing rather than telling. It autonomously opens pages in the browser tab, sets filters, and fills in forms. From a secur...

The in-house Python script behind eMudhra's October key compromise has now cost the company 8 more of its intermediate certificate authorities (CAs), even though it did not weaken their keys. Each intermediate CA has its own private key, which the company uses to sign the certificates it issues. The 8 intermediate CAs compromised in October had a different problem: a single line in the script cut each of their keys to one byte, the company said this week. The script also retrieved the RSA keys of the 8 newly revoked CAs from the company's hardware security modules (HSMs). The company says it cannot show that the keys were handled as required by its own rules. It revoked the CAs late last week. The company had called those CAs unaffected. "The RSA issuers went through a different path as per our assessment of the code and are therefore not impacted," it wrote on Mozilla's bug tracker on October 19. Of the 8, 6 were for website (TLS) certificates and 2 for...
