INC Ransom Claims Attack on Washington School For The Deaf
INC Ransom claimed a ransomware attack on Washington School For The Deaf. The group did not disclose any further information on the compromised data. The Washington School for the Deaf (WSD) is a school for deaf children located in Vancouver, Washington, in the United States. The school educates children from all over Washington.
Background on INC Ransom
INC Ransom was first observed in the summer of 2023, and it is unclear if they maintain a RaaS (Ransomware-as-a-Service) affiliate operation or are a closed group. INC uses common TTPs (Tactics, Techniques, and Procedures) such as leveraging compromised RDP (Remote Desktop Protocol) credentials to gain access and move laterally in a targeted environment.
Techniques and Tools Used by INC
INC has been observed delivering ransomware using legitimate tools like WMIC and PSEXEC and uses other Living-off-the-Land (LOTL) techniques, abusing applications including MSPaint, WordPad, NotePad, MS Internet Explorer, MS Windows Explorer, and AnyDesk for lateral movement. INC has also been observed abusing tools like Esentutl for reconnaissance and MegaSync for data exfiltration. INC is written in C++ and uses AES-128 in CTR mode to encrypt files, and it also has a Linux version. It is unclear if INC employs any advanced security tool evasion techniques, and there are indications that they may attempt to delete Volume Shadow Copies (VSS) to hinder encryption rollback attempts.
Targets and Extortion Practices of INC
INC targets a wide array of industries, including manufacturing, retail, IT, hospitality, pharma, construction, and the public sector. INC practices double extortion and maintains a leaks site for double extortion, threatening to expose victims. INC has made good on threats to expose sensitive data if a target does not pay the ransom demand.
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.
