Symantec Webinar | How to Detect Targeted Ransomware with MITRE ATT&CK
•
3 recomendaciones•565 vistas
Targeted ransomware attacks have grown significantly in recent years, targeting organizations specifically. These attacks spread to pre-selected organizations through methods like spear phishing and exploiting vulnerabilities. They encrypt files on multiple computers within an organization, demanding high ransom amounts from the few victims affected. The document discusses the growth of targeted ransomware gangs since 2017 and recommends defenses like backing up data, securing remote access points, and using PowerShell monitoring to help detect these threats.

Evasion Use ATT&CK for Cyber Threat Intelligence Cyber threat intelligence comes from many sources, including knowledge of past incidents, commercial threat feeds, information-sharing groups, government threat-sharing programs, and more. ATT&CK gives analysts a common language to communicate across reports and organizations, providing a way to structure, compare, and analyze threat intelligence. Use ATT&CK to Build Your Defensive Platform ATT&CK includes resources designed to help cyber defenders develop analytics that detect the techniques used by an adversary. Based on threat intelligence included in ATT&CK or provided by analysts, cyber defenders can create a comprehensive set of analytics to detect threats. Get Started with ATT&CK Legend APT28 APT29 Both Comparing APT28 to APT29 we've chosen 12 of those data sources to show the techniques each of them might be able to detect with the right colle analytics. Check out our website at attack.mitre.org for more information on how each technique can be detected, and adversary examples you can use to start detecting adversary behavior with ATT&CK. You can visualize how your own data sources map to adversary behavior with ATT&CK.
