Today's admins certainly have plenty on their plates, and boosting ecosystem security remains a top priority. On-premises, and especially remote, accounts are gateways for accessing critical information. Password management makes this possible. After all, authentication should ensure that a user is whom they claim to be. This initial layer of security is crucial for protecting one's entire infrastructure. Unfortunately, the personal nature of passwords has its shortcomings. Passwords are easily forgotten. They may also be too simplistic; many companies don't enforce stringent password-creation requirements. This is where the Active Directory Password Policy comes in. Additionally, the following is achievable: Changing user passwords Recording password changes and storing them within a history log Active Directory accounts for any impactful changes across user accounts. We'll assess why and how administrators might leverage these core features. Why change user ...

As more people work remotely, IT departments must manage devices distributed over different cities and countries relying on VPNs and remote monitoring and management (RMM) tools for system administration.  However, like any new technology, RMM tools can also be used maliciously. Threat actors can establish connections to a victim's device and run commands, exfiltrate data, and stay undetected.  This article will cover real-world examples of RMM exploits and show you how to protect your organization from these attacks.  What are RMM tools?  RMM software simplifies network management, allowing IT professionals to remotely solve problems, install software, and upload or download files to or from devices.  Unfortunately, this connection is not always secure, and attackers can use malicious software to connect their servers to a victim's device. As these connections become easier to detect, however,  ransomware-as-a-service (RaaS) groups have had to adjus...

This past week has been packed with unsettling developments in the world of cybersecurity.

Cybersecurity researchers today uncovered a new advanced version of ComRAT backdoor, one of the earliest known backdoors used by the Turla APT group, that leverages Gmail's web interface to covertly receive commands and exfiltrate sensitive data. "ComRAT v4 was first seen in 2017 and known still to be in use as recently as January 2020," cybersecurity firm ESET said in a report shared with The Hacker News. "We identified at least three targets: two Ministries of Foreign Affairs in Eastern Europe and a national parliament in the Caucasus region." Turla , also known as Snake, has been active for over a decade with a long history of the watering hole and spear-phishing campaigns against embassies and military organizations at least since 2004. The group's espionage platform started off as Agent.BTZ , in 2007, before it evolved to ComRAT , in addition to gaining additional capabilities to achieve persistence and to steal data from a local network. It...

Pro-Russian hacking groups have exploited a recently disclosed security vulnerability in the WinRAR archiving utility as part of a phishing campaign designed to harvest credentials from compromised systems. "The attack involves the use of malicious archive files that exploit the recently discovered vulnerability affecting the WinRAR compression software versions prior to 6.23 and traced as CVE-2023-38831," Cluster25  said  in a report published last week. The archive contains a booby-trapped PDF file that, when clicked, causes a Windows Batch script to be executed, which launches PowerShell commands to open a reverse shell that gives the attacker remote access to the targeted host. Also deployed is a PowerShell script that steals data, including login credentials, from the Google Chrome and Microsoft Edge browsers. The captured information is exfiltrated via a legitimate web service webhook[.]site. CVE-2023-38831 refers to a  high-severity flaw  in WinRAR that ...
