New Linux pedit COW Exploit Enables Root Access by Poisoning Cached Binaries

New Linux pedit COW Exploit Enables Root Access by Poisoning Cached Binaries

Jun 26, 2026 Linux / Vulnerability
A flaw in the Linux kernel's traffic-control subsystem can let a local unprivileged user gain root on affected systems. CVE-2026-46331 , nicknamed " pedit COW ," is an out-of-bounds write in the packet-editing action (act_pedit) that corrupts shared page-cache memory. A  public, working exploit  appeared within a day of the CVE assignment on June 16. Red Hat  rates the flaw as important . The exploit never touches the file on disk. It poisons the cached copy of a setuid root binary (/bin/su) in memory, injects a small payload, and runs that altered image as root. File-integrity checks come back clean while a root shell is already open. The exploit needs two things: act_pedit being loadable and unprivileged user namespaces being open, giving the attacker a namespace-local networking capability (CAP_NET_ADMIN) needed to trigger the bug. On the tested RHEL and Debian targets, both conditions were present. How the Bug Works Linux's tc traffic-...
Amazon Q Developer Flaw Could Let Malicious Repos Run Code via MCP Configs

Amazon Q Developer Flaw Could Let Malicious Repos Run Code via MCP Configs

Jun 26, 2026 AI Security / Vulnerability
A high-severity flaw in Amazon Q Developer let a malicious repository run commands and steal a developer's cloud credentials. The path was short: a developer opens the repo, trusts the workspace, and Amazon Q does the rest. Amazon has patched it. Tracked as  CVE-2026-12957  (CVSS 8.5), the bug sat in how Amazon's AI coding assistant handled Model Context Protocol (MCP) servers. Wiz Research, which found and reported it, showed that a single config file dropped in a repo was enough to go from git clone to cloud compromise. How the attack worked Amazon Q read an MCP configuration file, .amazonq/mcp.json, from the open workspace and launched the servers it defined. MCP servers are local processes that an AI assistant can spawn to reach databases, APIs, or build tools, so starting one means running commands on the machine. Those processes inherited the developer's full environment. That usually means AWS keys, cloud CLI tokens, API secrets, and SSH agent sockets. ...
CISA Adds Exploited PTC Windchill RCE Flaw to KEV as Web Shell Attacks Continue

CISA Adds Exploited PTC Windchill RCE Flaw to KEV as Web Shell Attacks Continue

Jun 26, 2026 Vulnerability / Software Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical remote code execution vulnerability impacting PTC Windchill PDMlink and PTC FlexPLM enterprise Product Data Management (PDM) and Product Lifecycle Management (PLM) software to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability in question is CVE-2026-12569 (CVSS score: 9.3), a case of improper input validation that could allow an attacker to execute arbitrary code by sending a malicious request to the network.  "The vulnerability is a remote code execution (RCE) issue that may be exploited through deserialization of untrusted data," according to an advisory released by PTC. Although patches for the flaw were released last week, PTC has since confirmed, as of June 25, that "we've received continued reports of heightened threat activity," with the company disclosing that unknown attackers are exploiting ...

New DirtyClone Linux Kernel Flaw Lets Local Users Gain Root via Cloned Packets

New DirtyClone Linux Kernel Flaw Lets Local Users Gain Root via Cloned Packets

Jun 26, 2026 Linux / Vulnerability
DirtyClone is a new Linux kernel privilege escalation in the DirtyFrag family. JFrog Security Research published a working exploit walkthrough for the flaw on June 25, the first public demonstration for this variant. Tracked as  CVE-2026-43503  (CVSS 8.8), it lets a local user corrupt file-backed memory through a cloned network packet and gain root. The patch landed in mainline on May 21; if your kernel does not have it, update now. When the kernel copies a network packet internally, two helper functions drop a safety flag that marks the packet's memory as shared with a file on disk. That missing flag is the entire vulnerability. The attacker loads a privileged binary like /usr/bin/su into memory, wires those memory pages into a network packet, and forces the kernel to clone it. The cloned packet passes through an IPsec tunnel that the attacker controls, and the decryption step overwrites the binary's login checks with attacker-chosen bytes. The next time anyo...
Guardian Agents: The Next Layer of Identity Governance

Guardian Agents: The Next Layer of Identity Governance

Jun 26, 2026 AI Security / Identity Governance
AI agents are moving through enterprise environments, inheriting permissions, traversing systems, and executing decisions at machine speed with minimal oversight. The identity infrastructure built to govern human access wasn't designed for autonomous actors, and the gap between what enterprises are deploying and what their governance programs actually cover is widening fast. This guide breaks down how the guardian agents emerged, why it matters, and what operationalizing it looks like in practice. The Governance Gap Agentic AI Created Identity governance has always lagged behind infrastructure change, but the arrival of production-grade agentic AI didn't just widen the gap. It changed its shape entirely. The assumptions baked into every IAM architecture built over the past two decades are no longer sufficient for the environment most enterprises are actually running today. Agents Aren't Service Accounts Security teams have spent years getting reasonably good at go...

Miasma Malware Targets npm Packages and GitHub Actions in Supply Chain Attack

Miasma Malware Targets npm Packages and GitHub Actions in Supply Chain Attack

Jun 26, 2026 Supply Chain Attack / Developer Security
Cybersecurity researchers have flagged yet another evolution of the supply chain attack linked to the Mini Shai-Hulud, Miasma, and Hades malware family that has compromised a new set of npm packages, even as it has propagated to the Go ecosystem. "The latest activity includes malicious npm releases affecting LeoPlatform and RStreams packages, GitHub Actions workflow abuse, and a related Go module compromise involving the Verana Blockchain project," Socket said . The end goal of the campaign, as before, is to harvest developer or maintainer credentials and weaponize the stolen data to spread across package registries, repositories, and trusted developer workflows. The list of affected packages is below - hexo-deployer-wrangler@1.0.4 hexo-shoka-swiper@0.1.10 leo-auth@4.0.6 leo-aws@2.0.4 leo-cache@1.0.2 leo-cdk-lib@0.0.2 leo-cli@3.0.3 leo-config@1.1.1 leo-connector-elasticsearch@2.0.6 leo-connector-mongo@3.0.8 leo-connector-mysql@3.0.3 ...
Microsoft Warns of Photo ZIP Phishing Campaign Targeting Hotels with Node.js Implant

Microsoft Warns of Photo ZIP Phishing Campaign Targeting Hotels with Node.js Implant

Jun 26, 2026 Phishing / Malware
An active phishing campaign has been targeting hotel and other hospitality organizations across Europe and Asia since April 2026, using photo-themed ZIP files to drop a Node.js implant and dig into front-desk machines, Microsoft says. The company has not attributed the activity to a known threat actor, and the operators' end goal is still unclear. The lure plays to how hotels work. Phishing emails carry the display name "Booking Manager (via Calendly)" and reference guest complaints, bedbug infestations, room inquiries, health inspections, and stay reviews. The lures came in Japanese, Danish, and Dutch, with Japanese the most common. The subject line names no recipient or property, which points to high-volume, list-driven sending rather than tailored spear phishing. The pressure is reputational: complaints, final warnings, threatened inspections. The delivery is the interesting part. The operators route messages through Calendly's email notification system a...
Russia Used Cellebrite on Jailed Activist's iPhone Months After Sales Cutoff

Russia Used Cellebrite on Jailed Activist's iPhone Months After Sales Cutoff

Jun 26, 2026 Mobile Security / Digital Forensics
Russian authorities used Cellebrite's UFED forensic tools to break into the iPhone of detained opposition activist Andrey Pivovarov in June 2021, three months after Cellebrite said it would stop selling its tools and services to Russia and Belarus. The finding, published  June 25 by the Citizen Lab , rests on two things that rarely line up: traces on the phone itself and an official Russian government report that names the tool. Investigators searched the extracted data for political contacts, opposition figures, and the names of activist organizations. This was not remote spyware. It was a forensic tool run on a seized device in custody, used to build a case in a political prosecution. Pivovarov ran Open Russia , an opposition group the Kremlin had branded "undesirable," a label that turned continued involvement into a criminal offense. He was  pulled off a flight  at St. Petersburg airport on May 31, 2021, and his iPhone 12 and MacBook were confiscated. He neve...
Google Details Turla's New STOCKSTAY Backdoor Used in Ukraine Espionage Attacks

Google Details Turla's New STOCKSTAY Backdoor Used in Ukraine Espionage Attacks

Jun 26, 2026 Cyber Espionage / Malware
The Russian state-sponsored threat actor known as Turla has been attributed to a previously undocumented .NET backdoor called STOCKSTAY that has been deployed against government and military organizations in Ukraine, and entities that have an interest in Italian foreign policy. Describing the Windows backdoor as continually developed by the hacking group, Google Threat Intelligence Group (GTIG) said the cyber espionage tool shares significant code and functional overlaps with Kazuar , a staple implant put to use by the adversary since 2017. Suspected development activity of malware dates back to December 2022. "STOCKSTAY is a multi-component backdoor written in .NET, using the Windows Forms framework, which communicates with its command-and-control (C2) via a secure WebSocket connection, utilizing the open-source websocket-sharp library," GTIG said . "STOCKSTAY consists of several distinct components that communicate with one another via an inter-process commu...

Chrome Ad Blocker with 10M+ Installs Found with Dormant Script Injection Capability

Jun 25, 2026 Browser Security / Malware
An analysis of a popular Google Chrome ad block extension for YouTube has uncovered the ability to execute arbitrary JavaScript code. According to Island, the extension, named Adblock for YouTube (ID: cmedhionkhpnakcndndgjdbohmhepckk), has more than 10 million installs and carries a Featured badge on the Chrome Web Store. The extension description states that it allows users to prevent web page elements like ads, including preroll ads, from being displayed on the video sharing platform, as well as on external sites that load YouTube. While the add-on offers the promised functionality, it also features capabilities to run arbitrary JavaScript code. "It also contains the architectural ingredients for arbitrary JavaScript execution on any website, activated by a single server-side configuration change, without an extension update, without a store review, and without any visible sign that something has changed," researchers Oleg Zaytsev and Shachar Gritzman said in a re...

Jun 25, 2026 Hacking News / Cybersecurity News
It’s dumb out there again. This week has the usual smell of prod on fire and nobody wanting to admit who left the door open — old creds still working, trusted apps doing sketchy crap, browser tricks jumping the fence, and “normal” workflows turning into phishing pipes because apparently email was not enough hell already. The worst part is how cheap some of it feels. Not elite. Not cinematic. Just stale secrets, fake updates, lazy trust, and random boxes quietly becoming someone else’s infrastructure. Same internet, fresh headache. Let’s get into it.

Surviving the Mythos Era: Richard Bejtlich on the Case for NDR

Jun 25, 2026 Artificial Intelligence / Threat Hunting
Despite the abundance of telemetry at analysts’ disposal, many security operations teams struggle to answer a few basic questions during incident investigation: What happened? What evidence do we have? How do we know we’re seeing it all, in context? Answering these questions requires teams to go beyond alerts, the most common basis for initial triage. But investigations (and their outcomes) require defensible evidence, not assumptions, which is what alerts tend to offer.  Alerts are becoming less useful as vulnerability discovery accelerates (a.k.a., the Mythos Era). Most organizations can’t investigate the volume of new findings with existing workflows. Even with increased automation, SecOps teams need validated evidence of active exploit and exposure, not more raw telemetry. As AI expedites both attacks and defense, security teams need to lay the groundwork that allows them to validate findings, understand attacker behavior, and stop suspicious traffic before it results in...
