Disabled by default, the attacker must make the user confident to enable them by clicking on the “yellow ribbon” on top of the document. Yesterday I found a malicious document that implements another approach. --------------------------------------------- https://isc.sans.edu/diary/rss/29810 ∗∗∗ How to Analyze Java Malware – A Case Study of STRRAT ∗∗∗ --------------------------------------------- STRRAT is a Java-based malware that executes multiple commands transmitted by the C2 server. The JAR file was obfuscated using the Allatori obfuscator. It establishes persistence on the host by copying to the Startup folder and creating a scheduled task and a Run registry entry.
