Analysis Summary

Heodo is a malicious program that is a variant of Emotet. Emotet was first identified in 2014. This malware is mostly disseminated through spam emails (malspam). Malicious scripts, document files with built-in macros, or malicious links can all deliver the infection. Emotet has undergone a few alterations.

Heodo malware can be used to download and execute other malware, steal personal or sensitive information, and so on. Heodo attack victims may incur a monetary loss, data loss, computer infection with additional viruses, identity theft, problems with online privacy, and other concerns. Threat actors use spam campaigns to deceive consumers into installing Heodo on their PCs. They send emails with a malicious Microsoft Word document that, when opened, requests access to information and modification or macros commands.

Remediation

• Block all threat indicators at your respective controls.
• Search for IOCs in your environment.
• Passwords - Ensure that general security policies include implementing strong passwords, correct configurations, and proper administration of security policies.
• Admin Access - limit access to administrative accounts and portals to only relevant personnel and make sure they are not publicly accessible.
• WAF - Web defacement must be stopped at the web application level. Therefore, set up a Web Application Firewall with rules to block suspicious and malicious requests.
• Patch - Patch and upgrade any platforms and software on time and make it into a standard security policy. Prioritize patching known exploited vulnerabilities and zero-days.
• Secure Coding - Along with network and system hardening, code hardening should be implemented within the organization to secure their websites and software. Use testing tools to detect any vulnerabilities in the deployed codes.
• 2FA - Enable two-factor authentication.
• Antivirus - Enable antivirus and anti-malware software and update signature definitions promptly. Using a multi-layered protection is necessary to secure vulnerable assets.
