Enterprise Security / Cyber Attack
Cybersecurity experts at Impress IT Solutions are alerting businesses in West Houston to an escalating ransomware threat posed by RansomHub, the most active ransomware group of 2024. With over 600 confirmed attacks worldwide, RansomHub has been targeting organizations across multiple industries, including healthcare, finance, government, and critical infrastructure.
How RansomHub Attacks Businesses
RansomHub operates as a Ransomware-as-a-Service (RaaS) operation, utilizing now-patched vulnerabilities in Microsoft Active Directory and the Netlogon protocol to escalate privileges and gain unauthorized access to a victim’s domain controller. Once inside the network, they deploy ransomware to encrypt critical data, demand ransom payments, and threaten data exposure if companies refuse to comply.
Methods Used by RansomHub
- Exploiting Microsoft Active Directory and Netlogon Vulnerabilities – Using known security flaws (CVE-2021-42278 and CVE-2020-1472) to take control of domain controllers.
- Brute-Force Attacks on VPN Services – Utilizing a dictionary of over 5,000 usernames and passwords to gain access.
- Lateral Movement and Network Compromise – Spreading across internal networks and encrypting key business data.
- Bypassing Security Solutions – Deploying tools like PCHunter to disable endpoint protection and FileZilla for data exfiltration.
- Leveraging Stolen Credentials for Persistent Access – Using credential harvesting to maintain long-term network presence.
Impact on West Houston Businesses
West Houston businesses, including construction, manufacturing, and IT service firms, are at heightened risk. A successful ransomware attack can result in:
- Data encryption and loss of access to critical files.
- Financial demands for ransom payments.
- Reputational damage and loss of customer trust.
