2025-01-24 • 没有评论

需要使用 CE 修改器搜索找到基准地址。

用以下计算工具计算微信版本 3.8.1.26 加尾号计算为 0x6308011a

CE 查询修改，找到六个地址，WechatWin.dll+XXXXX 这样

然后照着网上写个 python 写个修改工具

from pymem import Pymem

def fix_version(pm: Pymem):
    WeChatWindll_base = 0
    for m in list(pm.list_modules()):
        path = m.filename
        if path.endswith("WeChatWin.dll"):
            WeChatWindll_base = m.lpBaseOfDll
            break
            
    # 您提供的地址偏移量
    ADDRS = [
        0x2C43B7C,
        0x2C6421C,
        0x2C64370,
        0x2C7D238,
        0x2C80384,
        0x2C818C4
    ]
    
    for offset in ADDRS:
        addr = WeChatWindll_base + offset
        v = pm.read_uint(addr)
        if v == 0x63090a1b:  # 如果已经是目标版本，跳过
            continue
        elif v != 0x6308011a:  # 检查是否为当前版本 3.8.1.26
            raise Exception("版本不匹配，当前代码只适配微信版本3.8.1.26")
        pm.write_uint(addr, 0x63090a1b)  # 修改为目标版本 3.9.10.27
    print("修改完成，可以扫码登录了")

if __name__ == "__main__":
    try:
        pm = Pymem("WeChat.exe")
        fix_version(pm)
    except Exception as e:
        print(f"详细错误信息: {str(e)}")

可惜我不会逆向。
