The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added two security flaws impacting Palo Alto Networks PAN-OS and SonicWall SonicOS SSLVPN to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The flaws are listed below - CVE-2025-0108 (CVSS score: 7.8) - An authentication bypass vulnerability in the Palo Alto Networks PAN-OS management web interface that allows an unauthenticated attacker with network access to the management web interface to bypass the authentication normally required and invoke certain PHP scripts CVE-2024-53704 (CVSS score: 8.2) - An improper authentication vulnerability in the SSLVPN authentication mechanism that allows a remote attacker to bypass authentication Palo Alto Networks has since confirmed to The Hacker News that it has observed active exploitation attempts against CVE-2025-0108, with the company noting that it could be chained with other vulnerabilities like CVE-2024-9474...

Two security vulnerabilities have been discovered in the OpenSSH secure networking utility suite that, if successfully exploited, could result in an active machine-in-the-middle (MitM) and a denial-of-service (DoS) attack, respectively, under certain conditions. The vulnerabilities, detailed by the Qualys Threat Research Unit (TRU), are listed below - CVE-2025-26465 (CVSS score: 6.8)  - The OpenSSH client contains a logic error between versions 6.8p1 to 9.9p1 (inclusive) that makes it vulnerable to an active MitM attack if the VerifyHostKeyDNS option is enabled, allowing a malicious interloper to impersonate a legitimate server when a client attempts to connect to it (Introduced in December 2014) CVE-2025-26466 (CVSS score: 5.9) - The OpenSSH client and server are vulnerable to a pre-authentication DoS attack between versions 9.5p1 to 9.9p1 (inclusive) that causes memory and CPU consumption (Introduced in August 2023) "If an attacker can perform a man-in-the-middle a...

The Chinese state-sponsored threat actor known as Mustang Panda has been observed employing a novel technique to evade detection and maintain control over infected systems. This involves the use of a legitimate Microsoft Windows utility called Microsoft Application Virtualization Injector (MAVInject.exe) to inject the threat actor's malicious payload into an external process, waitfor.exe, whenever ESET antivirus application is detected running, Trend Micro said in a new analysis. "The attack involves dropping multiple files, including legitimate executables and malicious components, and deploying a decoy PDF to distract the victim," security researchers Nathaniel Morales and Nick Dai noted. "Additionally, Earth Preta utilizes Setup Factory, an installer builder for Windows software, to drop and execute the payload; this enables them to evade detection and maintain persistence in compromised systems." The starting point of the attack sequence is an execu...

Cybersecurity researchers are alerting to a new campaign that leverages web injects to deliver a new Apple macOS malware known as FrigidStealer . The activity has been attributed to a previously undocumented threat actor known as TA2727, with the information stealers for other platforms such as Windows ( Lumma Stealer or DeerStealer ) and Android ( Marcher ). TA2727 is a "threat actor that uses fake update themed lures to distribute a variety of malware payloads," the Proofpoint Threat Research Team said in a report shared with The Hacker News.  It's one of the newly identified threat activity clusters alongside TA2726, which is assessed to be a malicious traffic distribution system (TDS) operator that facilitates traffic distribution for other threat actors to deliver malware. The financially motivated threat actor is believed to be active since at least September 2022. TA2726, per the enterprise security firm, acts as a TDS for TA2727 and another threat actor ca...

Is AI really reshaping the cyber threat landscape, or is the constant drumbeat of hype drowning out actual, more tangible, real-world dangers? According to Picus Labs’ Red Report 2025 which analyzed over one million malware samples, there's been no significant surge, so far, in AI-driven attacks. Yes, adversaries are definitely continuing to innovate, and while AI will certainly start playing a larger and larger role, the latest data suggests that a set of well-known tactics, techniques, and procedures (TTPs) are still dominating the field. The hype around artificial intelligence has certainly been dominating media headlines; yet the real-world data paints a far more nuanced picture of which malware threats are thriving, and why. Here's a glimpse at the most critical findings and trends shaping the year's most deployed adversarial campaigns and what steps cybersecurity teams need to take to respond to them. Why the AI Hype is Falling Short…at Least For Now While headl...
