Tracing Ransomware Threat Actors Through Stylometric Analysis and Chat Log Examination
I stumbled upon an intriguing concept presented by Will Thomas (BushidoToken) in his blog post titled “Unmasking Ransomware Using Stylometric Analysis: Shadow, 8BASE, Rancoz.” This concept revolves around utilizing stylometry to identify potential modifications in new ransomware variants based on existing popular strains. If you’re interested, you can read the blog post here. (Notably, Will Thomas also appeared on Dark Net Diaries, discussing his tracking of the Revil ransomware.)
PindOS: New JavaScript Dropper Delivering Bumblebee and IcedID
Deep Instinct’s Threat Research Lab recently noticed a new strain of a JavaScript-based dropper that is delivering Bumblebee and IcedID. The dropper contains comments in Russian and employs the unique user-agent string “PindOS”, which may be a reference to current (and past) anti-American sentiment in Russia. Bumblebee is a malware loader first discovered in March 2022. It was associated with Conti group and was being used as a replacement for BazarLoader. It acts as a primary vector for multiple types of other malware, including ransomware. IcedID is a modular banking malware designed to steal financial information. It has been seen in the wild since at least 2017 and has recently been observed shifting some of its focus to malware delivery.

When Lexfo Security teased a critical pre-authentication RCE bug in FortiGate devices on Saturday 10th, many people speculated on the practical impact of the bug. Would this be a true, sky-is-falling level vulnerability like the recent CVE-2022-42475? Or was it some edge-case hole, requiring some unusual and exotic requisite before any exposure? Others even went further, questioning the legitimacy of the bug itself. Details were scarce and guesswork was rife.

Mercenary mayhem: A technical analysis of Intellexa's PREDATOR spyware
We would like to thank The Citizen Lab for their cooperation, support and inputs into this research. * Commercial spyware use is on the rise, with actors leveraging these sophisticated tools to conduct surveillance operations against a growing number of targets. Cisco Talos has new details of a commercial spyware product sold by the spyware firm Intellexa (formerly known as Cytrox). * Our research specifically looks at two components of this mobile spyware suite known as “ALIEN” and “PREDATOR,” which compose the backbone of the spyware implant. Our findings include an in-depth walkthrough of the infection chain, including the implants’ various information-stealing capabilities. * A deep dive into both spyware components indicates that ALIEN is more than just a loader for PREDATOR and actively sets up the low-level capabilities needed for PREDATOR to spy on its victims. * We assess with high confidence that the spyware has two additional components — tcore (main component) and kmem (privilege escalation mechanic) — but we were unable to obtain and analyze these modules. * If readers suspect their system(s) may have been compromised by commercial spyware, please consider notifying Talos’ research team at talos-mercenary-spyware-help@external.cisco.com to assist in furthering the community’s knowledge of these threats.
