The BlackCat/ALPHV Ransomware Attack on Clarion
The BlackCat/ALPHV ransomware gang has attacked Clarion. Clarion is a well-known manufacturer of in-car entertainment and audio systems, including car radios, speakers, multimedia systems, and navigation systems. The company has a long history in the audio and automotive industry. Clarion was founded in 1940 in Tokyo, Japan, and has grown to become a global brand in car audio and multimedia systems. They are known for producing high-quality audio products and integrated infotainment solutions for various vehicle manufacturers.
BlackCat/ALPHV posted Clarion to its data leak site on September 25th, claiming to have stolen confidential data about their business and their partners, engineering information of the company’s customers, and more.
Understanding BlackCat/ALPHV Ransomware
First observed in late 2021, BlackCat/ALPHV is a RaaS (Ransomware-as-a-Service) that employs a well-developed RaaS platform that encrypts by way of an AES algorithm. The code is highly customizable and includes JSON configurations for affiliate customization. BlackCat/ALPHV has the ability to disable security tools and evade analysis and is probably the most advanced ransomware family at present capable of employing different encryption routines, advanced self-propagation, and hinders hypervisors to for obfuscations and anti-analysis.
BlackCat/ALPHV can impact systems running Windows, VMWare ESXi, and Linux (including Debian, ReadyNAS, Ubuntu, and Synology distributions). BlackCat/ALPHV became one of the more active RaaS platforms over the course of 2022, and attack volumes in Q1 2023 continued to increase although it was overtaken by Cl0p in number of attacks in Q1 2023.
BlackCat/ALPHV typically demands ransoms in the $400,000 to $3 million range but has exceeded $5 million. BlackCat/ALPHV is the first ransomware group using Rust, a secure programming language that offers exceptional performance for concurrent processing. The ransomware deletes all Volume Shadow Copies using the vssadmin.exe utility and wmic to thwart rollback attempts and attains privilege escalation by leveraging the CMSTPLUA COM interface and bypasses User Account Control (UAC). It encrypts files with the ChaCha20 or the AES algorithm. BlackCat/ALPHV developers opted for faster over stronger encryption by employing several modes of intermittent encryption and employs a tool called Exmatter for data exfiltration.
Targeting and Impact
BlackCat/ALPHV has a wide variability in targeting, but most often focuses on the healthcare, pharmaceutical, financial, manufacturing, legal, and professional services industries. The group achieved a new low by publishing private, compromising clinical photographs of breast cancer patients exfiltrated during an attack. BlackCat/ALPHV also exfiltrates victim data prior to the execution of the ransomware – including from cloud-based deployments - to be leveraged in double extortion schemes to compel payment of the ransom demand. They have one of the more generous RaaS offerings, offering as much as 80-90% cut to affiliates. BlackCat/ALPHV is also noted for putting their leaks website on the public web instead of the dark web.
Recent Ransomware Attacks
The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.
The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
