nmap scripts don’t seem to be working
When I attempt to use an nmap script on a scan, there is no output relating to the scan and it only seems to do a normal search. I've tried using nmap in the scripts directory, specifiying the port for the script and tried many different scripts and nothing seems to work. Not sure what to do next.
sudo nmap --script sslv2-drown.nse https://nmap.org ) at 2021-07-14 13:48 EDT

Windows Hello Bypass Fools Biometrics Safeguards in PCs

A vulnerability in Microsoft’s Windows 10 password-free authentication system has been uncovered that could allow an attacker to spoof an image of a person’s face to trick the facial-recognition system and take control of a device.
A Windows security bug would allow an attacker to fool a USB camera used in the biometric facial-recognition aspect of the system.
Windows Hello is a feature in Windows 10 that allows users to authenticate themselves without a password, using a PIN code or biometric identity—either a fingerprint or facial recognition—to access a device or machine. According to Microsoft, about 85 percent of Windows 10 users use the system.
The Windows Hello bypass vulnerability, tracked as CVE-2021-34466, requires an attacker to have physical access to a device to exploit it, according to researchers at CyberArk Labs who discovered the flaw in March.
From there, they can go on “to manipulate the authentication process by capturing or recreating a photo of the target’s face and subsequently plugging in a custom-made USB device to inject the spoofed images to the authenticating host,” Omer Tsarfati, cybersecurity researcher at CyberArk Labs, wrote in a report about the vulnerability published Tuesday.
Further, exploitation of the bypass can extend beyond Windows Hello systems to “any authentication system that allows a pluggable third-party USB camera to act as biometric sensor,” Tsarfati noted.
See Also: Kaseya ransomware supply chain attack: What you need to know Researchers have no evidence that anyone has tried or used the attack in the wild, but someone with motive could potentially use it on a targeted espionage victim, such as “a researcher, scientist, journalist, activist or privileged user with sensitive IP on their device, for example,” according to the analysis.
Microsoft addressed the vulnerability — which affects both consumer and business versions of the feature — in its July Patch Tuesday update. Also, Windows users with Windows Hello Enhanced Sign-in Security — a new security feature in Windows that requires specialized and pre-installed hardware, drivers and firmware — are protected against the any attacks “which tamper with the biometrics pipeline,” according to Microsoft.
However, Tsarfati said that the solution may not fully mitigate the issue.
“Based on our preliminary testing of the mitigation, using Enhanced Sign-in Security with compatible hardware limits the attack surface but is dependent on users having specific cameras,” he said. “Inherent to system design, implicit trust of input from peripheral devices remains. To mitigate this inherent trust issue more comprehensively, the host should validate the integrity of the biometric authentication device before trusting it.” Biometric Weakest LinkCyberArk researchers posted a video of a proof-of-concept (PoC) for how to exploit the vulnerability, which can be used on both the consumer version, Windows Hello, and an enterprise version of the feature called Windows Hello for Business (WHfB) that businesses use with ActiveDirectory.
The bypass itself exploits a weakness in the biometric sensor of Windows Hello, which “transmits information on which the OS … makes its authentication decision,” he wrote. “Therefore, manipulating this information can lead to a potential bypass to the whole authentication system,” Tsarfati said.

For facial recognition, the biometric sensor is either a camera embedded in a device, such as a laptop, or connected to a computer via USB. Therefore, the entire process depends on this camera for proof of identity–which is where the vulnerability lies, particularly when a USB camera is used for authentication, he wrote.
“The answer lies in the input itself,” Tsarfati wrote. “Keyboard input is known only to the person who is typing before the information is entered into the system, while camera input isn’t.”
Therefore, using a camera to access “public” information—i.e., a person’s face—for authentication can easily be hijacked, he explained.
“It is similar to stealing a password, but much more accessible since the data (face) is out there,” Tsarfati wrote. “At the heart of this vulnerability lies the fact that Windows Hello allows external data sources, which can be manipulated, as a root of trust.” Attack VectorResearchers detailed a somewhat complex way for an attacker to capture someone’s image, save the captured frames, impersonate a USB camera device, and eventually send those frames to the Windows hello system for verification.
To prove the concept, they created a custom USB device that acts as a USB camera with both infrared (IR) and Red Green Blue (RGB) sensors, using an evaluation board manufactured by NXP. They used this custom camera to transmit valid IR frames of the person they were targeting, while sending the RGB frames image of the cartoon character SpongeBob SquarePants.
“To our surprise, it worked!” Tsarfati wrote. See Also: Hacking Stories: Andrian Lamo – The ‘homeless’ Hacker Based on this understanding, an attacker would only need to implement a USB camera that supports RGB and IR cameras and then send only one genuine IR frame of a victim to bypass the login phase of the device, while the RGB frames can contain any random image, he explained.
The entire process depends on an attacker having an IR frame of a potential victim to use in an attack, which can be done either by capturing one or converting one of the person’s regular RBG frames to an IR one, Tsarfati explained.
“Our findings show that any USB device can be cloned, and any USB device can impersonate any other USB device,” he said. “We used the IR frames of a person to ‘bypass’ the face recognition mechanism. We believe that those IR frames can be created out of regular color images.”

Fun with stickers and so are you!
Hey everyone! I was curious what you like to do with all your hacker stickers you've managed to collect. I've got a small but growing pile of them from a few different places. And while they're cool, I just can't manage to mar my laptop with them. That, and I feel bad using them. I somehow want to keep them but for some unknown reason.
Any cool and not typical uses you folks have come up with?
