Smashery continues to… smash it by updating our .NET assembly execution module. The original module allowed users to run a .NET exe as a thread within a process they created on a remote host. Smashery’s improvements let users run the executable within a thread of the process hosting Meterpreter and also changed the I/O for the executing thread to support pipes, allowing interaction with the spawned .NET thread, even when the other process has control over STDIN and STDOUT. The changes add more stealth, better I/O, more injection options, and reliability improvements.
We’re hiring a Security Researcher to develop high-quality modules and produce research that continues to inspire contributions and interest from a growing community. This role can be based on any of the following Rapid7 Offices: Austin TX, Boston MA, Arlington V, Boston MA, Tampa FL, Dublin, or our new Prague office! Seniority level is also flexible depending on experience and team fit.
