About Spoofing – Windows File Explorer (CVE-2025-24071) vulnerability

About Spoofing - Windows File Explorer (CVE-2025-24071) vulnerability

About Spoofing – Windows File Explorer (CVE-2025-24071) vulnerability. The vulnerability is from the March Microsoft Patch Tuesday. The VM vendors didn’t highlight it in their reviews. A week later, on March 18, researcher 0x6rss published a write-up and a PoC exploit. According to him, the vulnerability is exploited in the wild, and the exploit has likely been available for purchase since November 2024.

The point is this. When Windows File Explorer detects a .library-ms file in a folder, it automatically starts parsing it. If the file contains a link to a remote SMB share, an NTLM authentication handshake begins. An attacker controlling the SMB share can intercept the NTLMv2 hash, crack it, or use it in pass-the-hash attacks.

But how does an attacker deliver such a file to the victim? It turns out that just extracting a ZIP/RAR archive with the file is enough to trigger the exploit. No need to open the file.

This is super effective for phishing. 😱

Should a VM specialist be aware of what is happening in the Darknet?

Should a VM specialist be aware of what is happening in the Darknet?

Should a VM specialist be aware of what is happening in the Darknet? Of course. At least roughly. Otherwise, he’ll fall for the “nobody’s attacking us” myth. 😏

The reality is that every organization is under attack all the time. It’s like commercial fishing with trawlers. Anything that gets caught in the nets will be classified, priced, and put up for sale. 🐟 In today’s world of cybercrime, access to an organization’s infrastructure is a commodity. 🏪 The same is true for vulnerabilities, exploits, and ready-made malware.

Attacker groups have specialized:

🔻 some research vulnerabilities and write exploits
🔻 others embed them in malware
🔻 still others implement bypass of the InfoSec systems
🔻 the fourth get primary access
🔻 fifth people monetize this access 💰
🔻 sixth support the operation of trading platforms

And whether these guys can break your organization depends on you, VM specialist!

🟥 PT has published a large study on this topic. 👍

About Authentication Bypass – PAN-OS (CVE-2025-0108) vulnerability

About Authentication Bypass - PAN-OS (CVE-2025-0108) vulnerability

About Authentication Bypass – PAN-OS (CVE-2025-0108) vulnerability. PAN-OS is the operating system used in all Palo Alto Network NGFWs. This vulnerability allows an unauthenticated attacker to gain access to the PAN-OS management web interface. The attacker can then “invoke certain PHP scripts”, compromising the integrity and confidentiality of PAN-OS. 😏

🔹 The vendor bulletin was released on February 12. On the same day, Assetnote posted a write-up on the vulnerability. The next day, a PoC exploit appeared on GitHub.

🔹 On February 18, GreyNoise reported that they had detected active exploitation attempts. According to Palo Alto, the vulnerability is being exploited alongside EoP CVE-2024-9474 and Authenticated File Read CVE-2025-0111 vulnerabilities. As a result, the attacker gains the ability to execute Linux commands on the device as root. 😱

Install updates and restrict access to administrative web interfaces! 😉
