TeamViewer has fixed a flaw that lets the machine being controlled in a remote session attack the computer that connected to control it. In a TeamViewer session, the computer that connects and takes control is the viewer, and the machine it controls is the host. A malicious or compromised host can exploit the flaw to crash the viewer's TeamViewer and, depending on the platform, may also run code on the viewer's computer. This works only after the user starts a remote-control session to that host. The fix is in TeamViewer version 15.83. The flaw is tracked as  CVE-2026-111585  and scored 8.8 out of 10, in the high range. It affects the TeamViewer Full Client on Windows, Linux, and macOS, the Windows Portable edition, and the Android Remote Control app, in all versions before 15.83. For this flaw, TeamViewer's  bulletin  lists the Full Client, Portable, and Android app, but not the Host. The same 15.83 update fixes two other flaws in that bulletin that do affect...

Threat actors have been observed attempting to exploit a high-severity security flaw in WordPress Core shortly after patches were released. The vulnerability, which does not have a CVE identifier, relates to a case of remote code execution impacting WordPress Core versions 4.7 through 7.1.3. It carries a CVSS score of 8.1 on the CVSS scoring system. Patches for the flaw were released on October 28, 2026. "This is due to predictable, web-accessible staging paths used during full-package core upgrades," Wordfence said . "This makes it possible for unauthenticated attackers to execute code on the server during the upgrade window." The WordPress security company noted that successful exploitation requires an "attacker to hit a very narrow window while WordPress is unpacking a complete Core update." The issue boils down to the fact that affected versions unpack new files part of a full-package Core update into a predictable directory under "wp-co...

A Trezor Safe 5 hardware wallet bought from the reseller CryptoBilis has an extra circuit board that sends out the recovery phrase over a mobile network, a customer has reported. Trezor has not yet examined the device. It is telling everyone who bought a Trezor from CryptoBilis since March 2026 to move their funds to a new wallet with a new recovery phrase. Trezor said in a  blog post  on October 30 that the report came in two days earlier from a customer in Indonesia. He bought the wallet from CryptoBilis in August, through the marketplace Tokopedia. The board sits between the wallet's main board and its screen, with a cellular module and an antenna, according to the report. It reads the screen, including the recovery phrase (Trezor calls it the wallet backup), and sends it out whenever the device is plugged in. Trezor has the customer's photos and description and has interviewed him on a video call. It is arranging for the wallet to be sent to its lab. Trezor find...

The alert is critical. The fix is known. And the ticket sits in a queue for days. Security teams understand the risk, but the people who keep applications available need proof that the change won’t break anything.  Their concerns are practical. An IPS protection could block legitimate traffic. A configuration change could interrupt a service. An endpoint policy could affect an application the business depends on. Without evidence, the recommendation waits.  Safe remediation answers that hesitation with evidence. It tests the proposed action against your environment, applies the approved change, and confirms the result. Security and operations teams decide together, with facts.  The Cost of Leaving Protection in Detect  Many organizations already own protection they don’t enforce. Signatures sit inactive or in Detect mode while teams weigh false positives, inspection capacity, and business continuity. Meanwhile, applications and traffic patterns change, excep...

Ahmad Umar Agha , a Syrian Electronic Army hacker known online as " Th3Pr0 ," has been  sentenced by a U.S. federal court  to 42 months in prison for his role in a hacking conspiracy that targeted Western news outlets. The conspiracy was organized and led by members of former Syrian President Bashar al-Assad's inner circle, including the commander of Syria's General Intelligence Directorate, the U.S. Justice Department said on October 29. The pro-Assad Syrian Electronic Army began its attacks in 2011. Its members sent phishing emails to steal employees' passwords, then used those passwords to deface websites, redirect web traffic, and hijack social media accounts, according to a  2014 FBI affidavit . On April 23, 2013, the group hijacked the Associated Press's Twitter account and posted a false report that President Barack Obama had been injured in two explosions at the White House. Twitter's message confirming a password reset for that account w...

Cybersecurity researchers have disclosed that a trojanized version of Anthropic's official Claude Code extension was distributed through the Cursor Marketplace as a legitimate update, attempting to install a persistent SSH backdoor on affected systems. The malicious update, version 2.1.313, was distributed under the extension's legitimate publisher identity, prompting Cursor to temporarily shut down its marketplace to remove the compromised package. The exact method attackers used to introduce the unauthorized update remains unclear. "We identified a security incident affecting a modified Claude Code VS Code extension accessed through our Cursor IDE extension marketplace, impacting at most 5,000 users," Cursor said . "This malicious version of the extension was not developed by Anthropic. It does not impact other extensions downloaded from the cursor[.]com/marketplace, Grok Bot, Grok, or our other SpaceXSI product. However, Cursor's statement that the...

Drupal has warned that threat actors are exploiting a "highly critical" security flaw in its Commerce Core component. The vulnerability, tracked as CVE-2026-118539 (CVSS score: N/A), is a case of missing authorization affecting Commerce Core versions from 0.0.0 to 2.41 and from 3.0.0 to 3.3.13. "This module enables you to sell goods and services to customers through an included shopping cart and checkout form or through decoupled applications via APIs," Drupal said in an advisory. "The module doesn't sufficiently protect certain routes and entity fields, leading to an access bypass that may financially impact the vendor." The open-source content-management framework acknowledged that the vulnerability is being "actively exploited in the wild," but provided no specifics about the nature of the activity or the extent of the campaign. Users are being recommended to update to the latest version - Version 3.x - Upgrade to Commerc...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added two security flaws impacting Cisco and GitLab software to its Known Exploited Vulnerabilities ( KEV ), citing evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-97229 (CVSS score: 10.0) - An integer overflow or wraparound vulnerability in GitLab Community Edition and Enterprise Edition that could allow an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration due to insufficient regular expression validation. CVE-2026-76418 (CVSS score: 8.6) - An unchecked return value to NULL pointer dereference vulnerability in Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Secure Firewall Threat Defense (FTD) Software that could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial-of-service (DoS) condition. The devel...

Cryptocurrency giant Binance said on Thursday that a "security incident" on its platform has impacted about $6.3 billion worth of assets. The world's biggest cryptocurrency exchange said nearly $3 billion of those assets have been frozen on-chain so far.  Tether and Circle said they have frozen more than 1.567 billion USDT and 800 million USDC related to the incident, respectively. The Arbitrum Security Council is said to have executed a transaction to freeze about $30.5 million from the Binance Exploit.  "Initial investigation suggests that the security incident may involve a compromised DevOps engineer's laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions," Binance said in an update. The company said there is no evidence of a wallet private key leak, adding it will cover all losses from the Secure Asset Fund for Users ( SAFU ) fund and its own funds. Out of an abundance of c...

Some attacks take real skill. Others just need someone to leave a door open. This week has both. Exposed passwords, old bugs still getting exploited, and trusted software doing things it shouldn't. There's a strange mix of clever tricks and careless mistakes. Hackers are borrowing trust from familiar apps, websites, and AI tools. Some are using AI to speed things up. Others are leaving their own attack files exposed. Not exactly careful work. Different stories, familiar weak spots. Here's what showed up this week. The threats change every week.

A flaw in the Linux kernel's TCP code, tracked as  CVE-2026-98432 , affects Ubuntu, Red Hat Enterprise Linux (RHEL), and other Linux distributions. The kernel's own CVE team rates it 9.8 out of 10 on the CVSS scale. Anthropic said  on October 27 that its AI model wrote an exploit that uses the flaw to let a remote attacker with no credentials run commands as root on Linux servers with a multipath TCP listener. As of October 29, Ubuntu and RHEL have not released a fixed kernel. Red Hat, Amazon, Oracle, and SUSE score the flaw between 5.9 and 8.1, lower than the kernel team's 9.8. The flaw is a race condition in the code that sets up new IPv4 TCP connections. It can make the kernel read memory it has already freed, a bug type known as a use-after-free. The kernel fix  credits Anthropic researcher Xinyang Ge with reporting the bug. Neither the CVE record nor the fix mentions multipath TCP (MPTCP). The link between that feature and this bug comes from Anthropic'...

Threat actors are delivering malicious loaders and cryptocurrency miners under the guise of artificial intelligence (AI) desktop applications for Anthropic Claude and OpenAI ChatGPT as part of a campaign dubbed Yoba . The activity involves creating fake GitHub projects that claim to be desktop applications like GPT-5.6 Sol, GPT-6 Astra, and Claude Opus, only to deliver a malware family called YobaLoader. "The malware is placed next to legitimate, signed executables from OpenAI and Anthropic so it can be loaded indirectly, a technique commonly known as DLL sideloading, which is often used to bypass security protections," Check Point Research said in an analysis. To add to the project's credibility, the attackers set up GitHub.io pages to describe the capabilities of the software. Although the GitHub projects' popularity is not manipulated using techniques like ghost networks , signs point to the use of SEO poisoning tactics to ensure that links to them are sur...

Google on Wednesday took the wraps off Gemini 4 Carbon , its latest frontier model with state-of-the-art cybersecurity and long-horizon capabilities. "It shows significant gains across coding and agentic tasks as well as across key capabilities critical for cybersecurity defense, landing a firm lead in SEC-bench Pro (88.2%) for finding vulnerabilities, ExploitGym (54.8%) for exploitation, and CWE-bench (71.0%) for patching," Koray Kavukcuoglu, senior vice president of Google DeepMind and chief AI architect at Google, said . On the Artificial Analysis Intelligence Index benchmark, Carbon leads with a score of 59, surpassing Anthropic's Claude Opus 5.5 (58), OpenAI GPT-6 Astra (57), GPT-6.1 Sol (55). One of the core focus areas is cybersecurity, where the latest iteration reportedly delivers significant performance improvements across the board, including vulnerability detection, validation, and remediation. Carbon is also twice as likely to generate secure code ver...

Security teams have spent years trying to detect threats faster. AI is changing the harder part: how much time defenders have left to act. Advanced AI models can now help attackers discover vulnerabilities, generate exploit code, and move through weaknesses faster than traditional security processes were built to handle. The challenge is no longer just finding another vulnerability or generating another alert. It is knowing which exposures matter, what an attacker can reach, and which issues need to be fixed first. That is the focus of next week's webinar, How to Build AI Threat Readiness Across Your Security Operations , featuring an expert from Wiz. The session will show how security teams can improve visibility, prioritize real risk, and shorten the path from detection to remediation. Most security teams already have plenty of data. They have vulnerability findings, cloud alerts, identity signals, application telemetry, and threat detections. The harder problem is conne...

A flaw in Telegram for Android could be chained with two other bugs to take full control of a victim's phone through a voice call, once the victim answered, according to security startup NebuSec. The attacker needed only an ordinary Telegram account. Telegram fixed the flaw in version 12.10.4 of the app, released in late September, and NebuSec  disclosed it on October 29 . Combined with an information-leak bug, the flaw gives the attacker an escape from the Telegram app to Android, NebuSec co-founder and chief executive Eten Zou told The Hacker News. Adding an Android root exploit then gives full control of the phone, including its messages, microphone and camera. The flaw can be triggered in every version from 8.6.2 through 12.10.3, Zou said. Those versions came out between March 2022 and September 2026. The company confirmed it in private voice calls on ARM64-based phones and has no evidence so far that it directly affects Telegram's iOS and desktop apps or group ca...

AI is beginning to take over much of the work that has traditionally defined the security analyst's job. Investigating alerts, collecting evidence, correlating activity across tools, and executing response actions are becoming tasks that AI systems can perform on their own. As these capabilities mature, security operations centers (SOCs) will see major changes in how work is organized, how decisions are made, and what is expected of the people responsible for defending organizations. For security professionals, this is a chance to take on a much broader role. As AI assumes more of the operational workload, analysts can move beyond individual alerts and investigations to direct the defense across the entire security lifecycle. We call this emerging role the Threat Operator: an AI-native security professional who translates business risk into defensive priorities, directs AI-driven operations, and exercises judgment over the decisions and actions taken by those systems. The impa...
