Chinese state-sponsored threat actors have been observed using a Go-based artificial intelligence (AI)-powered penetration testing framework called ARTEX in attacks aimed at high-value targets simultaneously. The activity has been attributed by CrowdStrike to a China-based "targeted intrusion adversary" it tracks under the moniker Vapor Panda (previously VexatiousTemper). First identified in February 2021, the hacking group overlaps with a threat cluster detailed by Trend Micro as Earth Estries . "Agentic tooling like ARTEX enables this scale of expansion at speed, allowing a small team to pursue a wider target set than manual operations would support, rather than a wholesale shift away from the adversary's established access-development mission," CrowdStrike said in a Thursday analysis. Starting October 17, 2026, Vapor Panda is said to have used the AI tool against more than 200 distinct organizations across the world, including foreign ministries in ...

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-c...

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...
