Attackers hijacked Ukrainian websites to deliver a fake Cloudflare CAPTCHA that installs Psychedelic Stealer and steals browser and crypto credentials. Psychedelic Stealer is being distributed through compromised Ukrainian business websites. Attackers injected hidden iframes into legitimate pages and used them to display a fake Cloudflare verification screen…
The ‘SalesBleed’ set of weaknesses in Salesforce’s Agentforce agents exposed CRM data to attackers via prompt injection and DNS exfiltration
Cybersecurity researchers have flagged a new version of PamStealer that ensures that the main payload can only be recovered using a server-side decryption chain. The latest artifacts, per Jamf Threat Labs, continue to rely on the same JavaScript for Automation (JXA) dropper mechanism, but modify the lure and the delivery method. "Where earlier variants embed…
In 2023, Cloudflare declared itself free from CAPTCHAs with the launch of Turnstile, our privacy-first client-side challenge. Turnstile is free to use, works on any site (no need to proxy traffic through Cloudflare), and never asks a visitor to solve a puzzle. Now, we are launching Turnstile Spin, an agent-mediated end-to-end implementation of Turnstile. Ini…
Introduction
A domain that has long appeared in software documentation, code examples, and developer test material is now being used to push a ClickFix attack against Windows users. A placeholder domain stands in for a website in an example. The best-known is probably example.com . Another, third-party[.]com , has often been used in documentation to represent an external…

The CISA plan provides guidance and resources for election officials to secure systems such as voter registration databases and voting machines
A detection rule can show up as deployed on a coverage dashboard and still never fire when an attacker uses the technique it was built to catch. Conifers assessed 14,652 detections in its customer base, including rules written by customers and detections managed by vendors in SIEM, endpoint, cloud, identity, email and network tools. The research found that 4…
Researchers are questioning whether an OpenAI agent needed to hack an Australian government health portal to access it, after a review of the website’s archived code found it explicitly directed visitors to an unauthenticated endpoint.
CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-87902 WordPress Core Remote File Inclusion Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities . CISA will continue to add vulnerabilities to the catalog that meet the specified criteria . Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form . Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.

Security leaders keep debating whether AI will produce an entirely new class of cyberattack. The nearer change is quieter and already visible: AI has made a failed attack cheap to retry. The routine version looks like this. An attacker lands on a low-privilege cloud account, and the first try at privilege escalation goes nowhere. That dead end used to cost h…
