Microsoft Uncovers Flaws in ncurses Library Affecting Linux and macOS Systems

Sep 14, 2023 Endpoint Security / Vulnerability
A set of memory corruption flaws have been discovered in the  ncurses  (short for  new curses ) programming library that could be exploited by threat actors to run malicious code on vulnerable Linux and macOS systems. "Using environment variable poisoning, attackers could chain these vulnerabilities to elevate privileges and run code in the targeted program's context or perform other malicious actions," Microsoft Threat Intelligence researchers Jonathan Bar Or, Emanuele Cozzi, and Michael Pearse  said  in a technical report published today. The vulnerabilities, collectively tracked as  CVE-2023-29491  (CVSS score of 7.8), have been  addressed  as of April 2023. Microsoft said it also worked with Apple on remediating the macOS-specific issues related to these flaws. Environment variables are user-defined values that can be used by multiple programs on a system and can affect the manner in which they behave on the system. Manipulating t...
Free Download Manager Site Compromised to Distribute Linux Malware to Users for 3+ Years

Free Download Manager Site Compromised to Distribute Linux Malware to Users for 3+ Years

Sep 14, 2023 Supply Chain / Malware
A download manager site served Linux users malware that stealthily stole passwords and other sensitive information for more than three years as part of a supply chain attack. The modus operandi entailed establishing a reverse shell to an actor-controlled server and installing a Bash stealer on the compromised system. The campaign, which took place between 2020 and 2022, is no longer active. "This stealer collects data such as system information, browsing history, saved passwords, cryptocurrency wallet files, as well as credentials for cloud services (AWS, Google Cloud, Oracle Cloud Infrastructure, Azure)," Kaspersky researchers Georgy Kucherin and Leonid Bezvershenko  said . The website in question is freedownloadmanager[.]org, which, according to the Russian cybersecurity firm, offers a legitimate Linux software called "Free Download Manager," but starting in January 2020, began redirecting some users who attempted to download it to another domain deb.fdmpkg[.]...
Avoid These 5 IT Offboarding Pitfalls

Avoid These 5 IT Offboarding Pitfalls

Sep 14, 2023 SaaS Security / Cybersecurity
Employee offboarding is no one's favorite task, yet it is a critical IT process that needs to be executed diligently and efficiently. That's easier said than done, especially considering that IT organizations have less visibility and control over employees' IT use than ever. Today, employees can easily adopt new cloud and SaaS applications whenever and wherever they want, and the old IT offboarding playbook of "disable AD account, forward email, recover and wipe device, and call it a day" is no longer enough.  Here, we'll cover five of the most common pitfalls of  IT offboarding  in a SaaS-first world, along with advice on how to navigate around them. ‍ Pitfall #1: Suspending or deleting the email account before completing other critical steps It may seem logical to suspend or delete the employees' Google Workspace or Microsoft 365 account as the first step in the offboarding process. However, this will make the account inaccessible to everyone, even admins, which cou...

N-Able's Take Control Agent Vulnerability Exposes Windows Systems to Privilege Escalation

N-Able's Take Control Agent Vulnerability Exposes Windows Systems to Privilege Escalation

Sep 14, 2023 Vulnerability / Hacking
A high-severity security flaw has been disclosed in N-Able's Take Control Agent that could be exploited by a local unprivileged attacker to gain SYSTEM privileges. Tracked as  CVE-2023-27470  (CVSS score: 8.8), the  issue  relates to a Time-of-Check to Time-of-Use ( TOCTOU ) race condition vulnerability, which, when successfully exploited, could be leveraged to delete arbitrary files on a Windows system. The security shortcoming, which impacts versions 7.0.41.1141 and prior, has been addressed in version 7.0.43 released on March 15, 2023, following responsible disclosure by Mandiant on February 27, 2023. Time-of-Check to Time-of-Use falls under a category of software flaws wherein a program checks the state of a resource for a specific value, but that value changes before it's actually used, effectively invalidating the results of the check. An exploitation of such a flaw can result in a loss of integrity and trick the program into performing actions that it sh...
