Researchers discovered a private Telegram channel-based backdoor in the information stealing malware, dubbed Prynt Stealer , which its developer added with the intention of secretly stealing a copy of victims' exfiltrated data when used by other cybercriminals. "While this untrustworthy behavior is nothing new in the world of cybercrime, the victims' data end up in the hands of multiple threat actors, increasing the risks of one or more large scale attacks to follow," Zscaler ThreatLabz researchers Atinderpal Singh and Brett Stone-Gross  said  in a new report. Prynt Stealer, which  came to light  earlier this April, comes with capabilities to log keystrokes, steal credentials from web browsers, and siphon data from Discord and Telegram. It's sold for $100 for a one-month license and $900 for a lifetime subscription. The cybersecurity firm analysis of Prynt Stealer shows that its codebase is derived from two other open source malware families,  AsyncRAT  and 

It's no secret that sysadmins have plenty on their plates. Managing, troubleshooting, and updating software or hardware is a tedious task. Additionally, admins must grapple with complex webs of permissions and security. This can quickly become overwhelming without the right tools. If you're a sysadmin seeking to simplify your workflows, you're in luck. We've gathered some excellent software picks to help tackle different duties more efficiently.  Thankfully, these free tools are also respectful of tight budgets—without sacrificing core functionality. Best for Permissions Management: SolarWinds Permissions Analyzer for Active Directory Whether you are part of an organization with many members or numerous resources, keeping track of permissions can be challenging. Changes in responsibilities, titles, or even employment statuses can influence one's access to proprietary data. Each user has unique privileges. We not only need to visualize these but manage them on

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic

Tumblr posted a blog post Tuesday night warning users to change their passwords and released a very important security update for iOS users after identifying a breach that compromised their passwords. It seems that, under certain circumstances, the prior versions of the iPhone and iPad apps would allow an individual with malicious intent to sniff or intercept passwords as they are in transit across a local network. The problem arose because the iPad and iPhone apps fail to log users in through a secure server.  The vulnerability does not seem to have affected Tumblr's Android app. The company urged users to download the latest version of the Tumblr app, which is available in the Apple iTunes Store. The company did not provide further details on the breach. It's also good practice to use different passwords across different services by using an app like 1Password or LastPass. It doesn't appear that any passwords got in the hands of malicious individuals, though you
