Security researchers from Wazuh have recently uncovered a ransomware strain called Mamona that exemplifies how evolving threats render traditional defenses increasingly ineffective TechRadar.
Zero reliance on network infrastructure: Unlike conventional ransomware, Mamona operates entirely offline, not depending on command-and-control servers. This allows it to slip past systems that primarily monitor network activity.
Stealthy self-deletion: Upon execution, Mamona runs a simple three-second ping command (using an atypical address, 127.0.0.7) before deleting itself, leaving minimal forensic evidence.
Infection signals: It renames encrypted files with the .HAes extension and leaves a ransom note titled README.HAes.txt, but does so so quickly that even signature-based antivirus or file scanners may miss it.
Plug-and-play danger: Its simple, one-binary format dramatically lowers the barrier for cybercriminals to deploy it, accelerating the commoditization of ransomware tools.
Traditional ransomware protection focuses on detecting malware behavior or signatures—and then responding. But Mamona’s local, self-deleting execution and lack of network chatter make this model obsolete. If your systems only rely on detection, by the time you notice something, it’s often already too late.
Wazuh attempts to counter the threat using customized rules:
Sysmon integration for log collection;
Custom detection rules that flag ransom-note creation and self-deletion patterns;
YARA rules and real-time file integrity monitoring to trigger rapid responses on suspicious file changes.
But even these require significant tuning, ongoing maintenance, and still operate in a reactive mode.
At CHIPS, we’ve long advocated for a proactive security model—and that’s what AppGuard delivers today.
Isolation Over Detection
Instead of waiting to detect a threat, AppGuard isolates applications by default. Even if a threat like Mamona executes, its destructive capabilities are confined and cannot impact your critical systems.
Decade-Proven Track Record
With 10 years of consistent success, AppGuard has been trusted in high-stakes environments—and is now available for commercial use.
No reliance on signatures or behavior patterns
Since AppGuard prevents unauthorized actions at the OS level, it doesn’t matter how stealthy or ephemeral the threat is—self-deleting ransomware like Mamona can't evade containment.
We’re no longer dealing with straightforward attacks visible in network logs. Threats like Mamona operate in silence. To stay ahead, you must move from “Detect and Respond” to “Isolation and Containment.”
AppGuard offers just that. Don’t leave your response to luck or speed—it’s time to make containment the default.
Call to Action
Stop playing the crazy game of hoping detection kicks in quickly enough. Come over to the App Guard way of doing things. Business owners: talk with us at CHIPS about how AppGuard can prevent incidents like Mamona. Let’s help you shift your security posture from reactive detection to proactive containment—because preventing the damage is always better than chasing it.
