ja-netfilter

起源

ja-netfilter是 Neo 搞的一个开源项目。

Neo 之前搞得开源项目IDE Eval Resetter，是通过无限试用的方式来使用 JetBrains
全家桶，该项目在2021.2.2及以下版本很好用；2021.3以下（不含）堪堪能用，需要配合一些手法；2021.3版本开始正式失效。Neo 也已经弃坑，放弃了该项目。

接着搞了 ja-netfilter 项目，它是基于java agent技术的工具，通过编写插件的方式，依靠java agent技术进行AOP（Aspect-Oriented Programming，面向切面编程），可以对Java程序（也仅对Java程序才能使用）基于规则进行拦截和修改。但实际上，主要还是用于 JetBrains 家 IDE。

官网

Neo的个人博客是知了，可以参见其个人博客的详情介绍：ja-netfilter。

ja-netfilter 是开源项目，源码仓：https://gitee.com/ja-netfilter/ja-netfilter，码云还能用。不过，作者的GitHub已被封禁，原GitHub项目 ja-netfilter 已经成为历史。

其他，ja-netfilter的fork版本到处都是，推荐：

插件

url：这个插件用于禁止http(s)请求。如果待请求的URL和配置文件相匹配，则会抛出SocketTimeoutException。
dns：这个插件用于禁止指定域名的DNS解析。如果域名匹配，则会抛出UnknownHostException。
hideme：这个插件的功能是让别人不知道当前jvm存在ja-netfilter。
mymap：这个插件实现比较粗糙，仅是在调用Map.put时，如果key符合配置文件，那么就把待put的value替换为配置文件中对应的value。这种做法很暴力，容易造成冲突，不过，目前这个插件也已经被废弃掉了。
power：最核心的插件。这个插件hook了oddModPow函数，让这个函数返回自己想要的值。因为非对称加密常常使用这个函数，所以使用恰当的值来hook这个函数就能瞒天过海。其中ArgsFilter用来修改入参，ResultFilter用来修改返回结果。更多实例参见作者文章： Power插件应用：搞定YouTrack和Upsource、Power插件应用：搞定tinyMediaManager。

插件配置文件

插件目录里的配置目录里的插件、配置文件是一一对应关系。各个插件对应的配置文件为config目录中的${lower plugin name}.conf文件。

可以通过javaagent参数来指定目录，例如：-javaagent:/path/to/ja-netfilter.jar=appName 的配置、日志和插件目录将是config-appname、logs-appname和plugins-appname。

如果没有指定javaagent参数，目录默认为config、logs和plugins。

插件的综合应用

作者提到的热心大佬，主要是指：jetbra。

具体的应用举例：

非对称加密欺骗原理

非对称加密和数字证书

非对称加密技术简而言之就是使用私钥加密或签名，公钥验证签名或解密。数字证书则是公钥、私钥的封装形式。

非对称加密和数字证书相关详细内容，不再赘述，如有需要可查看：数字证书的制作和格式转换。

激活过程和欺骗手段分析

激活过程实际上就是使用公钥验证签名的过程。包含两个核心步骤：

验证公钥证书的可信性：确保公钥证书是由受信任的证书颁发机构（CA）签发，并且未被篡改或撤销。
使用公钥证书验证签名：利用证书中的公钥来确认签名的有效性，从而验证数据的完整性和来源的真实性。

欺骗手段分析：

验证公钥证书的可信性：使用ja-netfilter完成，通过java agent方式拦截验证函数，将x.modpow(y,z)的返回值改为fakeResult，这里即对应了power插件的配置文件power.conf里的配置内容：EQUAL,x,y,z->fakeResult。
使用公钥证书验证签名：生成自签名证书，然后使用自签名证书对自定义的信息（即产品激活信息）进行签名。签名是真实有效的，就是证书不是官方证书。

代码示例

第一步：生成自签名证书脚本

generate_cert.py 完成自签名证书的生成：

import datetimefrom cryptography import x509
from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import hashes, serialization
from cryptography.hazmat.primitives.asymmetric import rsa
from cryptography.x509.oid import NameOIDone_day = datetime.timedelta(days=1)
ten_day = datetime.timedelta(days=3650)
today = datetime.datetime.today()
yesterday = today - one_day
tomorrow = today + ten_dayprivate_key = rsa.generate_private_key(public_exponent=65537,key_size=4096,backend=default_backend()
)
public_key = private_key.public_key()
builder = x509.CertificateBuilder()builder = builder.subject_name(x509.Name([x509.NameAttribute(NameOID.COMMON_NAME, 'MoYuno-from-2022-07-25'),
]))
builder = builder.issuer_name(x509.Name([x509.NameAttribute(NameOID.COMMON_NAME, 'JetProfile CA'),
]))
builder = builder.not_valid_before(yesterday)
builder = builder.not_valid_after(tomorrow)
builder = builder.serial_number(x509.random_serial_number())
builder = builder.public_key(public_key)certificate = builder.sign(private_key=private_key, algorithm=hashes.SHA256(),backend=default_backend()
)
private_bytes = private_key.private_bytes(encoding=serialization.Encoding.PEM,format=serialization.PrivateFormat.TraditionalOpenSSL,encryption_algorithm=serialization.NoEncryption())
public_bytes = certificate.public_bytes(encoding=serialization.Encoding.PEM)
with open("ca.key", "wb") as fout:fout.write(private_bytes)
with open("ca.crt", "wb") as fout:fout.write(public_bytes)

第二步：使用自签名证书对产品激活信息进行签名

generate_key.py 完成对自定义的信息（即产品激活信息）进行签名。并按照 power.conf 和激活码的格式组织和输出相关内容。
