Microsoft says it has dismantled a criminal marketplace responsible for 1 billion malicious messages. Working with international authorities and several tech and cybersecurity companies in a nearly year-long investigation, Redmond identified and took down Yam Store, a coordinated underground network dealing in commercial phishing-as-a-service (PhaaS). The network allowed cybercriminals to readily purchase, and very q…
IntroductionZscaler ThreatLabz analyzed a recently active exploitation campaign in which a threat actor abused ARTEX to target South Korean financial institutions. ARTEX is an open source agentic penetration testing framework developed in China that uses large language models (LLMs) to automate reconnaissance and exploitation tasks. First observed in late September 2026, the campaign affected multiple South Korean fi…
CVE-2026-104935, a high-severity authentication bypass + RCE vulnerability, was only partially discovered and patched in July, leaving an opening for threat actors to capitalize on.
EFF legal intern Gabrielle Ladun was the principal author of this post. The Department of Homeland Security Office of Inspector General (DHS OIG) has published a summary of findings from its audit of the Transportation Security Administration’s (TSA) facial recognition technology. While the detailed findings are classified, the summary states that the OIG’s audit uncovered a “significant weakness” in the technology’s…
Stanislav Fort discovered that curl did not properly clear AWS SigV4 authentication state when CURLOPT_AWS_SIGV4 was set to NULL. An attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2026-86409) Stanislav Fort discovered that an HTTP proxy could trick libcurl into sending credentials to the proxy itself by responding to a CONNE…

This Cyble Research & Intelligence Labs (CRIL) weekly vulnerability report covers two views of risk: what attackers tried against Cyble's global honeypot sensors, and what the Cybersecurity and Infrastructure Security Agency (CISA) disclosed for industrial control systems (ICS). The Cyble Global Sensor Intelligence (CGSI) network observed exploitation attempts against about 20 known vulnerabilities. They range from n…
Simply asking Anthropic’s Claude Code to review an HTML file could hand attackers access to a developer’s machine, cloud credentials and software development environment, according to a new Noma Security finding. Noma’s researchers found a vulnerability affecting Anthropic’s Claude Code Desktop app that could allow malicious JavaScript embedded in an HTML file to execute without further user interaction, potentially…
An enterprise mail server authenticates users, stores private communications, delivers recovery links, runs calendars, and sends mail that employees and other systems trust. Compromising it can therefore expose both email and the identities and workflows built around it.During a broader assessment of Zimbra Collaboration Suite (ZCS), Rapid7 reported more than 80 vulnerabilities spanning authentication, mailbox author…
Overview Bisheng contains three vulnerabilities: a pre-authentication account takeover mechanism via a legacy single sign-on (SSO) endpoint; an Insecure Direct Object Reference (IDOR) vulnerability that exposes cross-user workflow data; and prior to version 2.5.0, authenticated attackers could perform cross-user LLM credential abuse and data disclosure due to missing service-layer access checks. Together, these flaws…
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday urged organizations to take steps to immediately update their Ivanti Connect Secure (ICS) appliances and deployments to the latest version following the disclosure of an actively exploited vulnerability. The security flaw, tracked as CVE-2026-104935 (CVSS score: 8.6), is a case of authentication bypass impacting ICS
It was discovered that OpenSSH's sftp client incorrectly handled paths returned by the server during a recursive copy operation. A remote attacker controlling the server could possibly use this issue to write files to unintended locations. (CVE-2026-106552) It was discovered that OpenSSH's sshd server incorrectly handled GSSAPIAuthentication state across authentication attempts. An attacker could possibly use this is…
CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

It was discovered that curl, when built with GnuTLS support, had an out-of-bounds read in the WebSocket send path. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-107928) Maksim discovered that curl did not correctly include the interface binding in connection reuse decisions when CURLOPT_INTERFACE was used. An attacker could possibly use this issue to cause connections to go out…
Attackers without an account of their own were found logging in to Ivanti Connect Secure appliances using an authentication bypass flaw that the vendor has since fixed. Once inside, attackers ran arbitrary commands on the appliances. “Ivanti initially discovered a portion of this vulnerability as part of our product security program and patched it in the July release 25.1.3.0,“ the vendor said in a security advisory.…
The bug was simple: the login let you choose where your sign-in code went. Proving it on a live website was the hard part. TL;DR During an authorized assessment, an AI pentesting agent found a critical authentication bypass on a major insurer's production website, on its own. One login request let the user choose where the one-time passcode went. The attack was the easy part. Proving it
When I started writing regularly about cybersecurity management in 2015, the environment looked very different. Cloud computing was still reshaping enterprise technology. Ransomware had not become the industrialised threat it is today. Artificial intelligence was not driving boardroom discussions. Zero Trust had yet to enter mainstream technical vocabulary and quantum computing barely registered on the corporate risk…
Since July, US frontier AI labs and other AI leaders have revealed a string of incidents in which their models accessed external computer systems without authorization, events popularly described as AI agents “going rogue.” The most well-known and studied of these incidents is OpenAI’s hack into Hugging Face, which OpenAI initially characterized as “an unprecedented cyber incident, involving state-of-the-art cyber ca…
SAP released its October 2026 security patch on Tuesday, October 13, delivering 22 new and updated security notes. Four of them address critical-severity vulnerabilities. The most severe is CVE-2026-89111, a maximum-rated flaw in the Cloud SDK for Python. Several of the bugs could allow attackers to invoke internal operations or execute code, which could lead to complete compromise of affected systems. SAP's patch da…

When quantum vendor IonQ on Sunday announced a $1.2 billion all stock deal to take over cybersecurity vendor Elisity, it spoke of a near-term future where enterprise quantum cybersecurity needs will move beyond replacing to-be-outdated encryption. The acquisition brings together IonQ’s post-quantum cryptography (PQC) and quantum key distribution (QKD) capabilities and Elisity’s enterprise Zero Trust technology platfo…
Microsoft released a record-shattering 1,407 CVEs to be plugged today on October Patch Tuesday, breaking the 2020 record of 1,261. The list was so long that its release was several hours later than the usual 1 p.m. Eastern drop time, somewhat frustrating admins. The bugs include three zero-day vulnerabilities, one of which has been exploited. The zero day being exploited, and that should be dealt with immediately, is…

Another month of patches equals another new record for Microsoft patches. It’s a good thing I survive Pwn2Own Ireland, because between these and the Adobe patches, there’s much to discuss. I’m also looking at different ways I can represent the bugs at this level of volume, so let me know if you have ideas. (Seriously – I’m out of ideas). If you’d rather watch the full video recap covering the entire release, you can…
