Check Point has patched two critical vulnerabilities in the way its firewall and management products handle VPN certificates. The company says both could allow an unauthenticated remote attacker to run code, but only "under specific conditions" that it has not described. One flaw affects Check Point's Security Gateways, its firewall appliances. The other affects those gateways and the Security Management Server, the console used to configure them. Check Point disclosed the flaws on September 9 in a  notice to its customer community , and began delivering fixes the same day. The company says it found both itself and has no indication that either has been used in an attack. The first flaw,  CVE-2026-85102 , is a failure to properly validate certificate trust during VPN negotiation. Its CVE record says an unauthenticated remote attacker may be able to run code on the Security Gateway. The second,  CVE-2026-85103 , is a heap-based buffer overflow that happens while t...

A suspected Russian-speaking cyber actor has been attributed to the use of artificial intelligence (AI) to devise exploits targeting a recently disclosed pair of security flaws in PaperCut NG/MF and break into hundreds of instances. According to independent reports from Blackpoint Cyber and GreyNoise , the activity originates from " 45.142.193[.]132 ," an IP address that has been linked to unauthorized port scanning and brute-force attack attempts in recent weeks. It's worth noting the same IP address was also flagged by Arctic Wolf in connection with the exploitation activity last week. "At this time, we cannot confirm the exact end goal of this campaign," Nevan Beal, principal MDR analyst at Blackpoint, told The Hacker News. "The threat actor's methodology is consistent with initial-access activity, but we do not yet have sufficient evidence to confirm whether they are operating as an initial access broker." At its core, the opportunist...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added three flaws, each impacting Cisco, Citrix, and Fortinet, to its Known Exploited Vulnerabilities ( KEV ) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the patches by September 12, 2026. The vulnerabilities are listed below - CVE-2026-20079 (CVSS score: 10.0) - An authentication bypass vulnerability in the web interface of Cisco Secure Firewall Management Center (FMC) Software that could allow an unauthenticated, remote attacker to bypass authentication and execute script files on an affected device to obtain root access to the underlying operating system. CVE-2026-19490 (CVSS score: 9.3) - An authentication bypass vulnerability in  Citrix NetScaler ADC and NetScaler Gateway when the appliance is configured as an AAA virtual server or as a Gateway (SSL VPN, ICA Proxy, CVPN, or RDP Proxy). CVE-2025-25249 (CVSS score: 7.3) - A heap-based buffer overflow ...

Nearly one in ten of the internet-facing LiteLLM servers that  Wiz Research  scanned in February accepted  sk-1234 , the example admin key in LiteLLM's own setup guide. LiteLLM is an open-source AI gateway, the software a company puts between its applications and the model providers it pays for. That key is the gateway's administrator credential. Anyone who holds it can read every model provider's API key stored on the server. In Wiz's tests, it also reached the cloud IAM credentials of the machine the gateway runs on. Changing the key needs no upgrade, and it closes every path in Wiz's report that depends on holding it. Where the Number Comes From Wiz ran one scan. It found 3,074 LiteLLM gateways on Shodan in February, and 294 of them accepted the key. In 191 of those 294, no key was set at all, so they would have accepted anything. The rest had the setup guide's value left in place. A second scan in August found more than 85,000 instances, but W...

Multiple espionage-motivated threat activity clusters have been found deploying a previously undocumented exploit kit called BlueMoon that chains together multiple vulnerabilities in Microsoft Windows and Google Chrome. The first in-the-wild use of BlueMoon has been attributed to the China-aligned state-sponsored group tracked as APT31 (aka Bronze Vinewood, Judgement Panda, JungleBamboo, PerplexedGoblin, RedBravo, TA412, Tide Castle, and Violet Typhoon) on August 28, 2026. "Within days, several other espionage-motivated clusters began using BlueMoon, the majority of which have a suspected China nexus," Proofpoint said in a report published today. "However, BlueMoon may not be exclusive to China-aligned actors, as some usage remains unattributed and there are also potentially more actors using the exploit kit." The exploit chain employs three vulnerabilities - CVE-2026-85046 , a type confusion in V8 in Google Chrome CVE-2026-87491 , an out-of-bounds...
