A new privilege escalation vulnerability has been identified in the Linux kernel by researcher Davide Ornaghi. This vulnerability might enable a local attacker to execute code on vulnerable computers with elevated rights if the kernel is installed on those systems. Additionally, Davide published the proof-of-concept and the write-up. The vulnerability, which has been assigned the tracking number CVE-2023–0179, is a stack-based buffer overflow that exists in the Netfilter subsystem. An authorized attacker might exploit this issue to get elevated privileges as root if the attacker executed a program that had been carefully written for the purpose.

The Linux kernel has a framework known as netfilter that enables a variety of networking-related actions to be performed in the form of individualized handlers. This may be accomplished by filtering incoming network packets. Netfilter provides the functionality necessary for directing packets through a network and preventing packets from reaching sensitive locations within a network by offering a variety of functions and operations for packet filtering, network address translation, and port translation. [1] These features allow Netfilter to provide the functionality required for directing packets through a network.

A group of hackers was able to take control of a decommissioned satellite and use it to stream a hacking conference’s talks and hacker movies.

On Saturday, at the DEF CON hacking conference in Las Vegas, Karl Koscher, one of the members of a hacking enthusiasts group called Shadytel, explained how he and his friends were able to legally stream from a satellite in geostationary orbit—35,786 km or 22,236 miles from the surface of the planet.

The satellite had been decommissioned and was about to be sent to the so-called “graveyard orbit,” a far-away orbit where satellites go to die.

With the explosive growth of technology, businesses are more vulnerable than ever to malicious cyber attacks. And as cybercriminals become more sophisticated, new methods of attack are popping up left and right.

To add fuel to the fire, the average cost of a data breach increased from $3.86 million to $4.24 million in 2021. That’s costly enough to put most SMBs into the red. Not to mention the reputational damage it can cause for your brand.

Making predictions is never easy, but it is agreed that cryptography will be altered by the advent of quantum computers.

Thirteen, 53, and 433. That’s the size of quantum computers.

Hacker group discloses the ability to encrypt an RTU device using ransomware, leading to reactions from Claroty and SynSaber.

The Guardian dice que un incidente cibernético a fines de diciembre de 2022 que provocó que el periódico británico cerrara sus oficinas durante semanas fue causado por ransomware e informó al personal el miércoles que los hackers habían accedido a sus datos.

Un correo electrónico enviado a su personal por la directora ejecutiva de Guardian Media Group Anna Bateson y la editora en jefe Katharine Viner dijeron que el ataque probablemente fue provocado por un correo electrónico de phishing.

Researchers from the cyber security firm Imperva Red Team have disclosed information on a newly found and fixed vulnerability that affected over 2.5 billion Google Chrome users as well as all Chromium-based browsers such as Edge and Opera.

The vulnerability, which is identified as CVE-2022–3656, makes it possible for remote attackers to acquire sensitive user data such as passwords for cloud service providers and knowledge about cryptocurrency wallets. After further investigation, it was determined that the problem was caused by the manner in which the Chrome browser dealt with symlinks when processing directories and files.

A new malware campaign has been observed targeting Italy with phishing emails designed to deploy an information stealer on compromised Windows systems.

“The info-stealer malware steals sensitive information like system info, crypto wallet and browser histories, cookies, and credentials of crypto wallets from victim machines,” Uptycs security researcher Karthickkumar Kathiresan said in a report.

Details of the campaign were first disclosed by Milan-based IT services firm SI.net last month.
