What is the difference with similar tools? Detect graftcp with Falco Conclusion A new network open source tool called graftcp (GitHub page) has been discovered in everyday attacks by the Sysdig Threat Research Team (TRT). Nowadays, threat actors try to improve their techniques by using new tools (as we mentioned in the PRoot article) to enhance the compatibility of their code to hit as many targets as possible and hide their traces properly.

The world of DevOps is constantly evolving and adapting to the needs of the software development industry.
