TunnelCrack: Two serious vulnerabilities in VPNs discovered, had been dormant since 1996

Posted by in categories: cybercrime/malcode, encryption, internet

The term “virtual private network,” or VPN for short, has become almost synonymous with “online privacy and security.” VPNs function by creating an encrypted tunnel through which your data may transit as it moves over the internet. They are designed to protect your privacy and make it impossible for anyone to monitor or access your activity while you are online. But what happens if the same instrument that was supposed to keep your privacy safe turns out to be a conduit for attacks? Introduce yourself to “TunnelCrack,” a frightening discovery that has sent shockwaves across the world of cybersecurity. Nian Xue from New York University, Yashaswi Malla and Zihang Xia from New York University Abu Dhabi, Christina Popper from New York University, and Mathy Vanhoef from KU Leuven University were the ones that carried out the study.

Two serious vulnerabilities in virtual private networks (VPNs) have been discovered by a research team. These vulnerabilities had been dormant since 1996. It is possible to leak and read user traffic, steal information, or even conduct attacks on user devices by exploiting these vulnerabilities, which are present in practically every VPN product across all platforms. TunnelCrack is a combination of two common security flaws found in virtual private networks (VPNs). Even though a virtual private network (VPN) is designed to safeguard all of the data that a user sends, these attacks are able to circumvent this security. An enemy, for example, may take advantage of the security flaws to steal information from users, read their communications, attack their devices, or even just spill it all. Regardless of the security protocol that is utilized by the VPN, the uncovered flaws may be exploited and used maliciously.

This code lets hackers remotely play music on Lexmark printers and spy on users

Posted by in categories: internet, media & arts, security

Researchers in the field of information security at Horizon3 have made public the proof-of-concept (PoC) code for a major privilege escalation vulnerability (CVE-2023–26067) found in Lexmark printers. On a device that has not been patched, this vulnerability, which has a CVSS score of 8.0, might enable an attacker to get elevated access if the device is not updated.

Incorrect validation of user-supplied information is what led to the vulnerability in the system. This vulnerability might be exploited by the attacker by having the attacker make a specially crafted request to the printer. Once the vulnerability has been exploited, the attacker has the potential to get escalated rights on the device, which might give them the ability to execute arbitrary code, spill credentials, or obtain a reverse shell.

Configurations prone to vulnerability An initial Setup Wizard is shown on the display of the user’s Lexmark printer the very first time it is turned on by the user. This wizard walks the user through the process of configuring several system settings, such as the language, as well as giving them the opportunity to setup an administrative user. If the user makes the selection “Set Up Later,” the printer will provide “Guest” users access to all of the features and pages available through the web interface of the printer. If the user selects “Set up Now,” the printer will prevent them from accessing a significant portion of their accessible capability until they have authenticated themselves.

China’s internet giants order $5 billion of Nvidia chips to power AI ambitions —FT

Posted by in categories: internet, robotics/AI

The Chinese groups had also purchased a further $4 billion worth of graphics processing units to be delivered in 2024, according to the report.

A Nvidia spokesperson would not elaborate on the report but said that consumer internet companies… More.


(Reuters)-China’s internet giants are rushing to acquire high-performance Nvidia chips vital for building generative artificial intelligence systems, making orders worth $5 billion, the Financial Times reported on Wednesday. Baidu, TikTok-owner ByteDance, Tencent and Alibaba have made orders worth $1 billion to acquire about 100,000 A800 processors from the U.S. chipmaker to be delivered this year, the FT reported, citing multiple people familiar with the matter. A Nvidia spokesperson would not elaborate on the report but said that consumer internet companies and cloud providers invest billions of dollars on data center components every year, often placing orders many months in advance.

LLMs like GPT and Bard can be manipulated and hypnotized

Posted by in categories: existential risks, finance, internet, robotics/AI

Hypnotized LLMs can help leak confidential financial information, generate malicious code and even cross red lights.

Tech pundits worldwide have been fluctuating between marking artificial intelligence as the end of all of humanity and calling it the most significant thing humans have ever touched since the internet.

We are in a phase where we are unsure what the AI Pandora’s box will reveal. Are we heading for doomsday or utopia?

Wealth on TikTok

Posted by in categories: computing, internet

Arnav Kapur, from MIT, has developed a device called AlterEgo, which allows him to surf the internet and perform tasks like ordering pizza using his mind. By internally vocalizing commands or questions, the device intercepts the electrical signals that would normally go to the vocal cords and sends them to a computer, which then communicates the information to Kapur’s inner ear through vibrations.

Microsoft to roll out new Teams Chat experience in Edge

Posted by in category: internet

Microsoft has unveiled an update on its Microsoft 365 roadmap, introducing a fresh chat experience within Microsoft Teams. This enhancement enables users to seamlessly open web links from chats in Microsoft Teams using Microsoft Edge. For example, when a user clicks on a web link within a chat, the link will now launch in Microsoft Edge, appearing alongside the ongoing Teams conversation. This feature promotes multitasking, allowing users to maintain their chat discussion while simultaneously viewing the linked web content.

The newly introduced feature is identified with the code 126,334 and was appended to the roadmap on August 4, 2023. This update is tailored exclusively for Microsoft Teams and pertains to the Worldwide (Standard Multi-Tenant) cloud instance. The platform for this development is the web.
