BlackCat/ALPHV Ransomware Group Targets Corsica Ferries
BlackCat/ALPHV ransomware group has added Corsica Ferries to their victim list. According to a post on X (Twitter), the ransomware group has published corporate data because the victim has failed to cooperate. The leaked documents include banking and billing information, personal data, and internal company files. Corsica Ferries - Sardinia Ferries is a Franco-Italian ferry company that operates traffic to and from the islands of Corsica, Sardinia, and Elba. Corsica Sardinia Ferries is the premier ferry operator on the Western Mediterranean Sea, transporting more than 2.8 million passengers annually aboard their ferries running to and from France and Italy to Corsica, Sardinia, and Elba.
Introduction to BlackCat/ALPHV
BlackCat/ALPHV was first observed in late 2021 and maintains a well-developed RaaS (Ransomware-as-a-Service) platform that encrypts by way of an AES algorithm. The code is highly customizable and includes JSON configurations for affiliate customization. BlackCat/ALPHV is adept at disabling security tools and evading analysis and is likely the most advanced ransomware family in the wild. BlackCat/ALPHV is capable of employing multiple encryption routines, displays advanced self-propagation, and hinders hypervisors for obfuscations and anti-analysis.
Impact and Ransom Demands
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 CI0p in a 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 recently released an API for their leak site to increase visibility for their attacks and put more pressure on victims to pay the ransom.
Technical Sophistication
BlackCat/ALPHV was the first ransomware developer to employ Rust, a secure programming language that offers exceptional performance for concurrent processing. BlackCat/ALPHV 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). BlackCat/ALPHV encrypts files with the ChaCha20 or the AES algorithm, opting for faster encryption versus stronger encryption by employing several modes of intermittent encryption.
BlackCat/ALPHV also employs a custom tool called Exmatter for data exfiltration. BlackCat/ALPHV released a new ransomware version called Sphynx in August with improved security evasion capabilities and was observed harvesting One-Time Passwords (OTP) to bypass security tools to drop the Sphynx payload and encrypt Azure cloud storage deployments. Researchers also observed a BlackCat/ALPHV variant that embeds tools like Impacket and RemCom to facilitate lateral movement and remote code execution. BlackCat/ALPHV has a wide variability in targeting, but most often focuses on the healthcare, pharmaceutical, financial, manufacturing, legal, and professional services industries.
Double Extortion Schemes
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.
