The Infection Monkey is an open source attack simulation tool designed to test the resilience of modern data centers and clouds against cyber attacks. It scans the network, checking for open ports and fingerprinting machines using multiple network protocols. After detecting accessible machines, it attempts to attack every single machine using methods such as intelligent password guessing and safe exploits. The Infection Monkey provides detailed information about the specific vulnerability exploited and the effect vulnerable segments can have on the entire network, giving security teams the insights they need to make informed decisions and enforce tighter security policies. The Infection Monkey is designed to be 100 percent safe, with no reconnaissance or propagation features that can impact server or network stability.
