The TellYouThePass ransomware family was recently reported as a post-exploitation malicious payload used in conjunction with a remote code execution vulnerability in Apache Log4j library, dubbed Log4Shell. TellYouThePass was first reported in early 2019 as a financially motivated ransomware designed to encrypt files and demand payment for restoring them. Targeting both Windows and Linux systems, TellYouThePass ransomware re-emerged in mid-December 2021 along with other ransomware like Khonsari.

It should come as little surprise that when enterprise and IT leaders turned their attention to the cloud, so did attackers. Unfortunately, the security capabilities of enterprises have not always kept up with the threat landscape. Poor visibility, management challenges and misconfigurations combine with other security and compliance issues to make protecting cloud environments a complex endeavor.

Following the Dec. 9, 2021, announcement of the Log4j vulnerability, CVE 2021-44228, CrowdStrike Falcon OverWatch™ has provided customers with unrivaled protection and 24/7/365 vigilance in the face of heightened uncertainty. To OverWatch, Log4Shell is simply the latest vulnerability to exploit — a new access vector among a sea of many others.

CrowdStrike’s goal is to stop breaches — and we do that better than any cybersecurity company in the world. As attackers advance their tactics and techniques, we continually refine our tools and capabilities to stay ahead of them. We recently added a new feature to the CrowdStrike Falcon® sensor: Hardware Enhanced Exploit Detection, which uses hardware capabilities to detect complex attack techniques that are notoriously hard for software alone to detect and prevent.

Note: This post first appeared in r/CrowdStrike. First and foremost: if you’re reading this post, I hope you’re doing well and have been able to achieve some semblance of balance between life and work. It has been, I think we can all agree, a wild December in cybersecurity (again). At this time, it’s very likely that you and your team are in the throes of hunting, assessing and patching implementations of Log4j2 in your environment.

Threat hunters and incident responders are under tremendous time pressure to investigate breaches and incidents. While they are collecting and sorting massive quantities of forensic data, fast response is critical to help limit any damage inflected by the adversary. This article and video will provide an overview of Falcon Forensics, and how it streamlines the collection and analysis of point-in-time and historic forensic data.

The recently discovered Log4j vulnerability has serious potential to expose organizations across the globe to a new wave of cybersecurity risks as threat actors look to exploit this latest vulnerability to execute their malicious payloads using remote code execution (RCE). An immediate challenge that every organization faces is simply trying to understand exactly where you have applications that are using this very popular Java library — but you are not facing this challenge alone.

Humio is a CrowdStrike Company. Data logging is the process of capturing, storing and displaying one or more datasets to analyze activity, identify trends and help predict future events. Data logging can be completed manually, though most processes are automated through intelligent applications like artificial intelligence (AI), machine learning (ML) or robotic process automation (RPA).

The Log4j vulnerability burst onto the scene just a few weeks ago, but to many defenders it already feels like a lifetime. It has rapidly become one of the top concerns for security teams in 2021, and seems set to remain so for the foreseeable future. The critical details of this threat evolve almost daily, making it a formidable challenge for defenders to keep tabs on the threat and their organizations’ exposure.
