Potatoes, EternalBlue, PrintNightmare: способы детектирования уязвимостей протокола SMB

Всем привет! Меня зовут Влад Кузнецов, я аналитик SOC в К2 Кибербезопасность . SMB — один из самых распространенных протоколов сетевой коммуникации для безопасного управления файлами и различными службами удаленного сервера. Несмотря на свою незаменимость, протокол SMB может быть отличной лазейкой для хакерских атак. В этой статье я расскажу о принципах эксплуатации и способах детектирования таких уязвимостей, как Potatoes, EternalBlue, PrintNightmare, а также о скрипте SMBExec. В конце материала вы найдете подробную информацию о настройке политик расширенного аудита и список общих рекомендаций по локализации и устранению уязвимостей, связанных с протоколом SMB.

Also be sure to turn on these monitoring policies in #DefenderForCloudApps so you can #CatchTheHacker before they get too deep, whether you switch to #Kerberos or not. #NetworkSegregation is also a great #LayeredDefense method to ensure if one system is compromised the attacker can't use #SMBtraversal to get to all your computers, globally. #EternalBlue source code is still being used to get to #DCs via #Trikbot evolutions, after #Phishing a user with #LocalAdmin privileges, to execute #mimikatz against #ActiveDirectory to steal all the objects. #YesThisHappened

✨ CVE-2022-37958:
Critical Windows code-execution vulnerability went undetected until now

▶️ Potential to rival EternalBlue

▶️ Wormable

▶️ Unlike EternalBlue, Vulnerability present in a much broader range of network protocols

▶️ Good news: patch was released in September. hopefully all of us applied it
