**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** This vulnerability could lead to a browser sandbox escape.

U.S. and South Korean intelligence agencies have issued a new alert warning of North Korean cyber actors' use of social engineering tactics to strike think tanks, academia, and news media sectors. The "sustained information gathering efforts" have been attributed to a state-sponsored cluster dubbed Kimsuky, which is also known by the names APT43, ARCHIPELAGO, Black Banshee, Emerald Sleet (

A critical flaw in Progress Software's in MOVEit Transfer managed file transfer application has come under widespread exploitation in the wild to take over vulnerable systems. The shortcoming, which is yet to be assigned a CVE identifier, relates to a severe SQL injection vulnerability that could lead to escalated privileges and potential unauthorized access to the environment.

This article is the fourth in a six-part series where we present various use cases for confidential computing—a set of technologies designed to protect data in use, like memory encryption, and what needs to be done to get the technologies’ security and trust benefits. In this article, we will focus on establishing a chain of trust and introduce a very simple pipeline called REMITS that we can use to compare and contrast various forms of attestation using a single referential. Part 1: Confidential computing primer Part 2: Attestation in confidential computing Part 3: Confidential

The latest on a newly discovered phishing botnet and the latest headlines regarding how countries use spyware.

Code-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software. This post is a deep dive on "Megatraffer," a veteran Russian hacker who has practically cornered the underground market for malware focused code-signing certificates since 2015.

An analysis of the "evasive and tenacious" malware known as QBot has revealed that 25% of its command-and-control (C2) servers are merely active for a single day. What's more, 50% of the servers don't remain active for more than a week, indicating the use of an adaptable and dynamic C2 infrastructure, Lumen Black Lotus Labs said in a report shared with The Hacker News. "This botnet has adapted

Ubuntu Security Notice 6127-1 - Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Gwangun Jung discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
