前段时间研究了一下facebook的ssl校验，后面发现facebook自己提供了去除ssl校验的设置。只需要开启即可。地址:cbdK9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6%4N6%4N6Q4x3X3g2X3j5h3y4W2j5X3!0G2K9#2)9J5k6h3y4G2L8g2)9J5c8Y4N6Z5K9i4c8W2K9r3q4@1i4K6u0r3M7X3g2K6k6h3q4J5j5$3S2W2M7W2)9J5k6s2y4W2N6s2c8A6L8X3N6K6i4K6u0r3。另外发现了另外一篇文章，详细描述了怎么绕过iOS端的证书校验b68K9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6%4N6%4N6Q4x3X3g2U0P5h3y4D9L8$3^5K6i4K6u0W2j5$3!0E0i4K6u0r3j5Y4W2H3j5i4y4K6i4K6u0V1k6X3q4U0k6h3u0G2L8$3E0Q4x3X3c8K6M7$3I4Q4x3X3c8U0k6i4u0@1K9h3k6A6j5$3q4@1k6g2)9J5k6s2m8A6L8X3&6A6L8X3N6Q4x3X3c8X3L8%4u0Q4x3X3c8A6L8%4x3`.。详细信息可以参考这里。本文所提供的脚本就是通过他这篇文章所描述的，写了一个frida脚本。就不用直接去patch二进制文件那么麻烦，直接用frida的patchcode功能。代码如下(20年7月12最新版278.0):

import { log } from "./logger";

let FBSharedFramework = Module.getBaseAddress("FBSharedFramework")
log(`FBSharedFramework : ${FBSharedFramework}`)

let maxPatchSize = 64;
var left = FBSharedFramework.add(0x1A53A8);
// b.ne #0x150
// 81 0A 00 54
log(`before: ${hexdump(left, { length: 8, ansi: true })}`);

Memory.patchCode(left, maxPatchSize, function(code){
    let cw = new Arm64Writer(code, {pc: left});
    cw.putBytes([0x80, 0x0a, 0x00, 0x54]); //b.eq #0x150
    cw.flush()
});

log(`after: ${hexdump(left, { length: 8, ansi: true })}`);

使用效果如下，可以正常的抓到facebook的包了
