Ransomware groups are using old tactics in new ways. This article details how attackers are using weaponized .HTA (HTML Application) files to deploy Red Ransomware payloads, often disguised as legitimate downloads. The result? Infected systems, encrypted data, and operational disruption. Read the article to learn how these attacks work and where your defenses could break down. Then contact Capgemini to assess your risk and identify opportunities to strengthen endpoint and user protection.
What are weaponized .HTA files?
Weaponized HTML (.HTA) files are malicious files that exploit vulnerabilities in web browsers to deploy ransomware, such as the Epsilon Red strain. In recent attacks, these files are disguised as verification pages, tricking users into downloading them. Once executed, they can run scripts that bypass security measures, leading to data encryption and potential data loss.
How do attackers lure victims?
Attackers often create spoofed verification portals branded as 'ClickFix' that appear legitimate. They target users of popular platforms like Discord, Twitch, Kick, and OnlyFans. By exploiting users' trust, they prompt them to 'prove' their authenticity, leading to the download of weaponized .HTA files that initiate the ransomware attack.
What can organizations do to protect themselves?
Organizations can enhance their security by disabling ActiveX and Windows Script Host (WSH), enforcing modern browser policies, and continuously blacklisting known malicious domains and IP addresses. Additionally, implementing user-focused phishing simulations and deeper network hardening can help mitigate risks associated with these attacks.
