Hi,

I have a target that uses SentinelLM v8.1. The target has an exe that launches a java program.


What call would be used to launch the java or how is it likely to be launched from the exe file?
Is it likely that the java program is what sentinel use? There does not seem to be much documentation on Sentinel and java.

thanks in advance

SentinelLM is software protection. It is no Sentinel dongle protection (respective it can be connect wih sentinel dongle, but also you can make license which will not required dongle)

Without much technical detail, I have SEEN plenty of java applications that came packed as exe. I am not into digging them right now but they do exist a plenty. I did a search in google using "Java exe files" and came with 2000000 initial hits, several in the first page are relevant. Exe files with java inside are often used as packing, deployment, optimization and protection mechanisms, so I think the answer to the question which Call is used? is complex: It depends.

What call would be used to launch the java or how is it likely to be launched from the exe file?

Once again multiple possible implementations: it may unpack a JAR file in memory, then run from there in the java VM, or it may have compiled some JAVA code into native code and run in native form. All those solutions are explored in some of the initial articles http://www.excelsior-usa.com/articles/java-to-exe.html .

Is it likely that the java program is what sentinel use? There does not seem to be much documentation on Sentinel and java.

I have seen C# packs using sentinel protections. there is not reason why a Java app could not use sentinel for license management, usually calling sentinel generated .dlls

thanks in advance
