Unix | Breaking Cybersecurity News | The Hacker News

As many as six security vulnerabilities have been disclosed in the popular Rsync file-synchronizing tool for Unix systems, some of which could be exploited to execute arbitrary code on a client. "Attackers can take control of a malicious server and read/write arbitrary files of any connected client," the CERT Coordination Center (CERT/CC) said in an advisory. "Sensitive data, such as SSH keys, can be extracted, and malicious code can be executed by overwriting files such as ~/.bashrc or ~/.popt." The shortcomings, which comprise heap-buffer overflow, information disclosure, file leak, external directory file-write, and symbolic-link race condition, are listed below - CVE-2024-12084 (CVSS score: 9.8) - Heap-buffer overflow in Rsync due to improper checksum length handling CVE-2024-12085 (CVSS score: 7.5) - Information leak via uninitialized stack contents CVE-2024-12086 (CVSS score: 6.1) - Rsync server leaks arbitrary client files CVE-2024-12087 (CVSS ...

A new wormable botnet that spreads via GitHub and Pastebin to install cryptocurrency miners and backdoors on target systems has returned with expanded capabilities to compromise web applications, IP cameras, and routers. Early last month, researchers from Juniper Threat Labs documented a crypto-mining campaign called " Gitpaste-12 ," which used GitHub to host malicious code containing as many as 12 known attack modules that are executed via commands downloaded from a Pastebin URL. The attacks occurred during a 12-day period starting from October 15, 2020, before both the Pastebin URL and repository were shut down on October 30, 2020. Now according to Juniper, the  second wave of attacks  began on November 10 using payloads from a different GitHub repository, which, among others, contains a Linux crypto-miner ("ls"), a file with a list of passwords for brute-force attempts ("pass"), and a local privilege escalation exploit for x86_64 Linux systems.

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
