Chainalysis Confirms Intrusion Into Internal Tools and Exposure of Customer Identity Data

American blockchain analysis firm Chainalysis said it was the target of a cybersecurity incident in which an external actor accessed non-sensitive customer data. However, the company noted that the breach did not result in unauthorized access to its investigation content, authentication credentials, or session tokens. "This month, Chainalysis detected an external actor using offensive agentic techniques to gain unauthorized access to Chainalysis systems and internal tools," Chainalysis said Friday. "Some non-sensitive customer data, such as user IDs, full names, email addresses, and organization role labels for users provisioned on our platform were accessed, including such information relating to your organization and users." The company said it's patching vulnerabilities and hardening its systems in response to the incident. The mention of "offensive agentic techniques" indicates that an artificial intelligence (AI)-powered tool was used ...

Attackers Chain Three Ivanti Connect Secure Flaws to Gain Unauthenticated Root Access

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two security flaws impacting Ivanti Connect Secure (ICS) to its Known Exploited Vulnerabilities ( KEV ) catalog, following active exploitation in the wild. The vulnerabilities are listed below - CVE-2026-111357 (CVSS score: 8.8) - A missing authentication for a critical function vulnerability that could allow a local authenticated attacker to escalate their privileges. CVE-2026-118527 (CVSS score: 4.3) - A generation of predictable numbers or identifiers vulnerability that could allow a remote authenticated attacker to upload files with attacker-controlled content to a known location on disk. It's worth noting that the security bugs are part of an exploit chain that was first documented by Volexity earlier this month as weaponized in conjunction with an authentication bypass flaw (CVE-2026-104935, CVSS score: 8.6) by a previously undocumented threat actor dubbed UTA0576. CVE-2026-10493...

A Shared ChatGPT Link Could Run Attacker Code in Your Session and Read Private Chats

A malicious ChatGPT share link could run an attacker's code in the logged-in session of anyone who opened it, allowing them to read their private conversations, researchers at the security firm Parameter showed. The researchers reported the flaw through  OpenAI's bug bounty program  on October 18, and OpenAI fixed it eight days later and rated it P1, its most serious category. The trap was an ordinary ChatGPT conversation shared via its public link. It could be sent the same way as any real shared chat: by email, as a chat message, as a support ticket, or as a social post. The victim did not have to install anything, join a workspace, or sign in through the attacker. In the most reliable version of the attack, they opened the link and clicked ChatGPT's Preview button once. In a later version, Parameter set the page to open Preview on its own, so opening the link was the only step. What the Attacker Could Do Once the link opened, the attacker's code ran ins...

Cloudflare Reports 18.2 Million Network-Layer DDoS Attacks in Q3, Up 38%

Threat actors are launching about 8,226 network-layer distributed denial-of-service (DDoS) attacks per hour, Cloudflare revealed Thursday. The web infrastructure and security company said it autonomously mitigated 18.2 million network-layer (L3) DDoS attacks and 14.4 trillion HTTP DDoS requests in the third quarter of 2026. That amounts to 197,400 attacks per day, or one attack every 0.44 seconds. In comparison, a total of 13.2 million and 10.0 million L3 DDoS attacks were recorded in Q2 and Q1 2026, respectively. The increase has been linked to DDoS-for-hire booter or stresser services that are responsible for hundreds of thousands of attacks.  "Short-burst, low-bandwidth attacks lasting under 10 minutes and 1 Gbps surged by 208%," the Cloudforce One threat intelligence team said in its quarterly DDoS Threat Report shared with The Hacker News. An interesting trend is the decline of hyper-volumetric attacks exceeding 1 Tbps by 69% from the previous quarter – going ...

Chinese Hackers Use AI-Powered ARTEX to Target Over 200 Organizations Worldwide

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 Flaw Lets Remote Computers Attack Users Who Connect to Control Them

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...

WordPress RCE Flaw Draws Nearly 63,000 Attack Attempts in Just 24 Hours

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...

Trezor Warns of Suspected Hardware Implant in One of Its Wallets Sold by CryptoBilis

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...
