The critical vulnerabilities, which impact default configurations of NetScaler products, essentially give attackers a skeleton key to customers' networks.
Kiteworks on Monday said it worked with federal intelligence authorities over the weekend as it identified and addressed a critical security vulnerability during the scheduled precautionary shutdown. "During the shutdown, this activity led to the discovery of a previously unknown critical vulnerability confined to a capability that is enabled for less than 1% of the customer base," the company
Pentagon personnel agency breach exposed data of 3 million people after attackers accessed a file-sharing server for about nine months. The U.S. Defense Manpower Data Center (DMDC), which maintains personnel records for the Department of Defense, is notifying people that their personal information was exposed in a data breach. According to the agency, unauthorized users […]
Identity governance helps control who should have access, but periodic reviews alone may not reveal attacks as they happen. tenfold Software explains how real-time identity telemetry can help security teams investigate suspicious activity before it escalates. [...]
Introduction In late September 2026, Mandiant Consulting and Google Threat Intelligence Group (GTIG) identified active, in-the-wild exploitation of a zero-day vulnerability (CVE-2026-88772) affecting Citrix NetScaler ADC and NetScaler Gateway appliances. We have observed evidence that organizations in North America and Europe in the government, financial services, technology, education, and legal and professional services sectors were likely impacted by this exploitation campaign, which has bee…
Cybersecurity researchers have identified a cluster of 101 npm packages that are used to trap developers into a WhatsApp group subscriber campaign dubbed PhantomSub. "The malicious packages abuse the 'Baileys' WhatsApp open source project to add the victims to groups without their consent," OX Security researchers Nir Zadok, Moshe Siman Tov Bustan, and Vitalii Chepurko said in a technical

We’re building CryptoLabe, an internal AI-powered tool that discovers cryptography across our codebase, surfaces dependencies, and helps us progress toward a full post-quantum migration by 2029. Here’s what we’ve learned so far.
Twelve years after launching Universal SSL, Cloudflare is applying to become a certificate authority. By combining an established root, an ACME-first approach, and Merkle Tree Certificates, we are building a post-quantum CA for the open web.
As post-quantum signatures threaten to inflate TLS handshakes and certificate transparency logs, Merkle Tree Certificates offer a path to compact, auditable authentication. Cloudflare’s new certificate authority will support MTC issuance at scale.
We are expanding access to Cloudforce One's Threat Events Platform to every Cloudflare account and introducing Threat Signals. Threat Signals automatically parses open-source threat reporting, extracts structured indicators, and connects threat context directly to your WAF rules.
Cloudflare has added visibility into post-quantum (PQ) encryption in TLS 1.3 directly into HTTP Analytics, Log Explorer, and Logpush. Learn how to make sure your domain is protected with PQ encryption.
Cloudflare learns the structure of your HTTP requests and identifies deviations. You can add a positive security layer that helps reduce attack surface as AI makes it easier for attackers to generate and vary payloads.
According to Dodo Pizza, the potentially compromised information included customers’ names, addresses, email addresses, phone numbers, dates of birth and order details.
