Threat Roundup for January 7 to January 14


Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Jan. 7 and Jan. 14. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats.

As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net.

Newsletter compiled by Jon Munshaw.

Good afternoon, Talos readers.  

Move out of the way, Log4j! Traditional malware is back with a bang in 2022. While Log4j is likely still occupying many defenders' minds, the bad guys are still out there doing not-Log4j things. We have new research out on a campaign spreading three different remote access tools (RATs) using public internet infrastructures like Amazon Web Services and Microsoft Azure Sphere.

If you're looking to unwind after all the Log4j madness, we also have a new Beers with Talos episode that's one of our more laid-back productions. We, unfortunately, said goodbye to Joel, but it was not without tequila and discussions about "Rent."

We joked when recording this episode that it wouldn't come out until Groundhog Day, so technically we're a few weeks early! Unfortunately, it comes with a shred of bad news — Joel is leaving us. We're now only down to two OG Beers with Talos hosts, but we still have exciting times ahead with Mitch, Matt, Liz and future guests. 

Don't expect any real cybersecurity discussion in this one. We gotta be honest, it went pretty off the rails.

Nanocore, Netwire and AsyncRAT spreading campaign uses public cloud infrastructure

By Chetan Raghuprasad and Vanja Svajcer.

  • Cisco Talos discovered a malicious campaign in October 2021 delivering variants of Nanocore, Netwire and AsyncRATs targeting user's information.
  • According to Cisco Secure product telemetry, the victims of this campaign are primarily distributed across the United States, Italy and Singapore.
  • The actor used complex obfuscation techniques in the downloader script. Each stage of the deobfuscation process results with the decryption methods for the subsequent stages to finally arrive at the actual malicious downloader method.
  • The campaign is the latest example of threat actors abusing cloud services like Microsoft Azure and Amazon Web Services and are actively misusing them to achieve their malicious objectives.
  • The actor is using the DuckDNS dynamic DNS service to change domain names of the C2 hosts.

Executive Summary

Threat actors are increasingly using cloud technologies to achieve their objectives without having to resort to hosting their own infrastructure. These types of cloud services like Azure and AWS allow attackers to set up their infrastructure and connect to the internet with minimal time or monetary commitments. It also makes it more difficult for defenders to track down the attackers' operations.

The threat actor in this case used cloud services to deploy and deliver variants of commodity RATs with the information stealing capability starting around Oct. 26, 2021. These variants of Remote Administration Tools (RATs) are packed with multiple features to take control over the victim's environment to execute arbitrary commands remotely and steal the victim's information.

The initial infection vector is a phishing email with a malicious ZIP attachment. These ZIP archive files contain an ISO image with a malicious loader in the form of JavaScript, a Windows batch file or Visual Basic script. When the initial script is executed on the victim's machine, it connects to a download server to download the next stage, which can be hosted on an Azure Cloud-based Windows server or an AWS EC2 instance.

To deliver the malware payload, the actor registered several malicious subdomains using DuckDNS, a free dynamic DNS service. The malware families associated with this campaign are variants of the Netwire, Nanocore and AsyncRAT remote access trojans.

Organizations should be inspecting outgoing connections to cloud computing services for malicious traffic. The campaigns described in this post demonstrate increasing usage of popular cloud platforms for hosting malicious infrastructure.

Andrew F4A-PDM-20-NX1 20 FT SureFlex Assembly Cable %


By Jon Munshaw and Vitor Ventura. 

Microsoft released its monthly security update Tuesday, disclosing 102 vulnerabilities across its large collection of hardware and software. This is the largest amount of vulnerabilities Microsoft has disclosed in a monthly security update in eight months, however, none of the issues have been exploited in the wild, according to Microsoft. 

2022’s first security update features nine critical vulnerabilities, with all but one of the remaining being considered “important.”

Vulnerability Spotlight: Two vulnerabilities in Adobe Acrobat DC could lead to arbitrary code execution



Aleksandar Nikolic of Cisco Talos discovered these vulnerabilities. Blog by Jon Munshaw. 

Cisco Talos recently discovered two vulnerabilities in Adobe Acrobat Reader DC that could allow an attacker to eventually gain the ability to execute arbitrary code.  

Acrobat is one of the most popular PDF reader software options available currently. It includes the ability to read and process JavaScript to give PDFs greater interactivity and customization options for users. Both vulnerabilities exist in the way Acrobat Reader processes JavaScript.  

TALOS-2021-1387 (CVE-2021-44710) is a use-after-free vulnerability that is triggered if the user opens a PDF with specially crafted, malicious JavaScript. The code could give attackers control over reused memory, which can lead to arbitrary code execution.

Vulnerability Spotlight: Heap buffer overflow condition in Google Chrome could lead to code execution



Marcin Towalski of Cisco Talos discovered this vulnerability. Blog by Jon Munshaw. 

Cisco Talos recently discovered an exploitable heap-based buffer overflow vulnerability in Google Chrome.  

Google Chrome is a cross-platform web browser — and Chromium is the open-source version of the browser that other software developers use to build their browsers, as well. This specific vulnerability exists in WebRTC, a technology that enables websites to capture and stream audio or video and other data between browsers. 

TALOS-2021-1372 (CVE-2021-37979) is a heap-based buffer overflow vulnerability that triggers if the user opens a specially crafted web page in Chrome. That page could trigger a heap buffer overflow and memory corruption error in the application and buffer overflow, which could lead to code execution.

Vulnerability Spotlight: Buffer overflow vulnerability in AnyCubic Chitubox plugin



Carl Hurd of Cisco Talos discovered this vulnerability. Blog by Jon Munshaw. 

Cisco Talos recently discovered an exploitable heap-based buffer overflow vulnerability in the Chitubox AnyCubic plugin. 

Chitubox is 3-D printing software for users to download and process models and send them to a 3-D printer. The specific AnyCubic plugin allows the software to convert the output of the Chitubox slicer (general format files) into the format expected by AnyCubic's series of printers. These converted files are then used directly for all functionality provided by the printers. 

TALOS-2021-1376 (CVE-2021-21948) is a heap-based buffer overflow vulnerability that triggers if the user opens a specially crafted .gf file.
