Two security vulnerabilities have been discovered in the remote monitoring and management software (RMM) N-central from N-able, which allow attackers to inject commands into the operating system or execute malicious code that has been smuggled in. The Shadowserver Foundation published an evaluation of the Internet scans for X on the weekend. According to this, 1077 IP addresses were vulnerable to the vulnerabilities CVE-2025-8875 and CVE-2025-8876 last Friday. Last week, the US IT security authority CISA included the vulnerabilities in the “Known Exploited Vulnerabilities” catalog.

Cybersecurity researchers have identified a significant increase in malicious scanning activities originating from compromised consumer and enterprise networking equipment, with particular focus on Cisco, Linksys, and Araknis router models. The Shadowserver Foundation, a prominent threat intelligence organization, has reported observing unusual scanning patterns that suggest widespread compromise of these networking devices.

The cybersecurity community faces a significant threat as scanning data reveals over 28,000 unpatched Microsoft Exchange servers remain exposed on the public internet, vulnerable to a critical security flaw designated CVE-2025-53786. The vulnerability affects Microsoft Exchange Server hybrid deployments, with scanning data from The Shadowserver Foundation identifying the United States, Germany, and Russia as the top three countries harboring the highest concentrations of exposed vulnerable servers. The Cybersecurity and Infrastructure Security Agency (CISA) has assessed this as a high-severity vulnerability with significant implications for enterprise security.

A massive exposure of Microsoft SharePoint servers to internet-based attacks has been identified, with over 17,000 servers exposed and 840 specifically vulnerable to the critical zero-day vulnerability CVE-2025-53770, according to new findings from Shadowserver Foundation.

Several U.S. federal agencies have been confirmed as victims, including the Department of Energy’s National Nuclear Security Administration, the Department of Homeland Security, the Department of Health and Human Services, and the Department of Education. State and local government agencies have also been impacted across the country.

In the first half of 2025, evidence of exploitation for the 432 KEVs added to VulnCheck was first observed across more than 74 unique sources, highlighting the importance of having broad source coverage to ensure the earliest detection of exploitation. A comparison can be seen from the 1H-2024 state of exploitation report.

Before publishing this article, VulnCheck produced a blog about Auditing ShadowServer for Unassigned CVEs. They said: We performed an extensive audit of ShadowServer’s daily detection snapshots. During this process, we identified vulnerabilities with active detections but no associated CVE ID, a major blind spot for defenders relying on structured vulnerability intelligence. Rather than let these gaps persist, we tracked down the original advisories and/or exploit proof-of-concepts and issued CVEs ourselves. In total, we contributed 30+ new CVEs through this audit process where exploitation evidence existed.

A sweeping cyber espionage operation targeting Microsoft server software compromised about 100 organizations as of the weekend, two of the organizations that helped uncover the campaign said on Monday. Microsoft on Saturday issued an alert about “active attacks” on self-hosted SharePoint servers, which are widely used by organizations to share documents and collaborate within organizations. Vaisha Bernard, the chief hacker at Eye Security, a Netherlands-based cybersecurity firm, which discovered the hacking campaign targeting one of its clients on Friday, said that an internet scan carried out with the Shadowserver Foundation had uncovered nearly 100 victims altogether – and that was before the technique behind the hack was widely known.

At least 10,000 CrushFTP instances are vulnerable to a critical flaw, which is currently being exploited by attackers, affecting the file transfer solution, according to cybersecurity experts. The vulnerability, tracked as CVE-2025-54309, involves a mishandling of AS2 validation in all versions of CrushFTP servers prior to 10.8.5 and prior to 11.3.4_23. It can be exploited when the demilitarized zone (DMZ) proxy feature is not used.  On July 21, the Shadowserver Foundation reported observing 1040 unpatched CrushFTP instances, with the top affected countries being the US, Germany and Canada.

A widespread cyberattack campaign has successfully compromised dozens of Fortinet FortiWeb instances through webshell deployment, exploiting a critical vulnerability for which proof-of-concept code became publicly available just days ago. The attacks center around CVE-2025-25257.  The Shadowserver Foundation, a prominent threat monitoring organization, has been tracking the exploitation campaign since it began on July 11. Their latest data reveals concerning statistics about the scope of compromised systems.

Between 14 and 17 July, a joint international operation, known as Eastwood and coordinated by Europol and Eurojust, targeted the cybercrime network NoName057(16). Law enforcement and judicial authorities from Czechia, France, Finland, Germany, Italy, Lithuania, Poland, Spain, Sweden, Switzerland, the Netherlands and the United States took simultaneous actions against offenders and infrastructure belonging to the pro-Russian cybercrime network. The investigation was also supported by ENISA, as well as Belgium, Canada, Estonia, Denmark, Latvia, Romania and Ukraine. The private parties ShadowServer and abuse.ch also assisted in the technical part of the operation.

Security researchers have confirmed active exploitation of a critical vulnerability in Wing FTP Server, just one day after technical details were publicly disclosed. The flaw, tracked as CVE-2025-47812, has received the maximum CVSS score of 10.0 and enables unauthenticated remote code execution with root or SYSTEM privileges. The Shadowserver Foundation has identified around 2,000 IPs running exposed Wing FTP Server instances, though specific vulnerability checks have not been conducted on all identified systems.
