Healthcare and services provider Nutex is investigating a data breach incident where an unauthorized third party exfiltrated information from company servers. The organization has disclosed the cyberattack in a filing with the U.S. Securities and Exchange Commission (SEC), noting that the stolen data includes details that may be private or confidential. “Based on preliminary findings from the Company’s ongoing investigation, the Company believes that certain information maintained on the Company’s servers was accessed and exfiltrated by an unauthorized third party, including some information that may be private and/or confidential,” Nutex says. Nutex Health is a for-profit healthcare company that operates 28 facilities across 12 states, including the Bayou City ER & Hospital in Texas and Green Bay ER & Hospital in Wisconsin.
Threat actors have already compromised over 270 Zimbra instances in remote code execution attacks targeting a high-severity Zimbra Collaboration Suite (ZCS) vulnerability. The ZCS email and collaboration suite is used by hundreds of millions of people and organizations, including thousands of businesses and hundreds of government agencies worldwide. Synacor patched the security flaw (tracked as CVE-2026-73570), which allows unauthenticated attackers to gain code execution remotely by exploiting a command injection weakness in the SNMP monitoring component when SNMP notifications are enabled, with the release of ZCS version 10.1.20 on July 20. CERT Polska, the Polish Computer Emergency Response Team (CERT), first flagged the vulnerability as targeted in the wild last Monday, when it also warned security teams to check their logs for suspicious activity, including the Zimbra service restarting unexpectedly, and for files created in the /opt/zimbra/jetty/webapps/, /opt/zimbra/jetty_base/webapps/, and /tmp/ folders by user zimbra over the last 30 days.
Law enforcement agencies from 22 countries helped identify 263 suspects and arrested 58 individuals linked to cybercrime networks coordinated by African crime groups. The "Operation Jackal IV" international joint action targeted West African criminal networks between November 2025 and June 2026. The operation also focused on disrupting the Black Axe cybercrime syndicate, known for its involvement in global-scale cyber-enabled financial fraud. Most commonly, Black Axe and similar criminal rings are targeting victims in romance scams, cryptocurrency and investment scams, or business email compromise fraud, but they've often also been linked to violent crimes. During Operation Jackal IV, Argentinian law officers made 17 arrests, and they linked 196 suspects to a major Crime-as-a-Service network that provided West African organized crime groups with web domains and money-laundering support.

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Oracle flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added an Oracle HTTP Server and Oracle Weblogic Server Proxy Plug-in flaw, tracked as CVE-2026-21962 (CVSS score of 10,0), to its Known Exploited Vulnerabilities (KEV) catalog. CVE-2026-21962 is a critical, unauthenticated vulnerability affecting the Oracle HTTP Server and Oracle WebLogic Server Proxy Plug-in for Apache HTTP Server and IIS. An attacker does not need an account or valid credentials. With network access, they can exploit the flaw remotely through HTTP and potentially compromise the affected server. Successful exploitation could allow the attacker to access, modify or delete critical data, potentially gaining broad access to information available through the affected components. “Oracle HTTP Server and Oracle WebLogic Server Proxy Plug-in contain an improper access control vulnerability that can result in unauthorized creation, deletion, or modification access to critical data as well as unauthorized access to critical data or complete access to all Oracle HTTP Server and Oracle WebLogic Server Proxy Plug-in accessible data,” CISA reports. The vulnerability also has a scope-change impact, meaning an attacker who exploits it could potentially affect other systems or applications connected to the vulnerable Oracle components. The flaw affects versions: 12.2.1.4.0, 14.1.1.0.0 and 14.1.2.0.0. In practical terms, this is dangerous because an internet-accessible Oracle WebLogic proxy component could provide an attacker with a path into critical backend systems without requiring authentication. In March 2026, CloudSEK researchers detected attacks targeting several known flaws in Oracle WebLogic against its honeypot network. Attackers also targeted CVE-2026-21962 along with older WebLogic RCE vulnerabilities, including CVE-2020-14882/14883, CVE-2020-2551 and CVE-2017-10271. “This report analyzes attack data collected from a high-interaction honeypot simulating a vulnerable Oracle WebLogic Server (v14.1.1.0.0) over a 12-day period (Jan 22 – Feb 3, 2026). The primary focus is the immediate and widespread exploitation of the newly disclosed, critical unauthenticated Remote Code Execution (RCE) vulnerability, CVE-2026-21962 (CVSS: 10.0).” ” reads the report published CloudSEK. “In addition to CVE-2026-21962, the honeypot captured attacks targeting other persistent, critical WebLogic RCE flaws, including CVE-2020-14882/14883 (Console RCE), CVE-2020-2551 (IIOP RCE), and CVE-2017-10271 (WLS-WSAT RCE). This confirms that threat actors continue to rely on a small set of highly-effective, simple-to-exploit vulnerabilities to compromise WebLogic environments.” According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaw by August 27, 2026.

Marimo has addressed a high-severity security flaw in its notebook software that allowed an attacker to execute an attacker-supplied Model Context Protocol (MCP) command in a specially crafted notebook, according to VulnCheck's CVE Numbering Authority (CNA) record. The CNA record says the command can run as a local subprocess when the notebook is opened in edit mode. The vulnerability, tracked
Cybersecurity researchers have disclosed details of a new campaign that uses a cluster of 24 npm packages as free phishing infrastructure for redirecting to ClickFix-style fake CAPTCHA pages. "While the malware is simply a single HTML page inside the npm package, and while downloading it wouldn't do harm, the threat actor’s use of npm isn't to infect developers who install it, but to use the
Cybersecurity researchers are calling attention to a new campaign that employs FTP banners as dead drop resolvers (DDRs) to deliver two previously unreported remote access trojans (RATs) tracked as E4del and PINHOLE. While threat actors are known to abuse legitimate services to point to additional command-and-control (C2) infrastructure and blend in with regular network traffic, the development
Vulnerability management has been a staple of security programs since the dawn of the cybersecurity discipline. The symbiotic relationship between vulnerability and patch management teams has also existed for that time and has gone through waves of contention and thankfulness. While this relationship required thoughtful care and feeding from both sides, both sides were aiming to work toward a
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a maximum-severity security flaw impacting Oracle HTTP Server and Oracle WebLogic Server to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-21962 (CVSS score: 10.0), allows an unauthenticated attacker with network access via HTTP to
