This is a post for people that beg for Free Fire IPA cheats, or wanna make one themself (any questions PM me or give me a tele) Here u will find all the sideloading + simulator detections so let’s get started. 1. Official fingerprints (App Store): Team - 98573T3W6L App id. - 98573T3W6L.com.dts.freefireth Bundle id - com.dts.freefireth Free Fire CDHash SHA256-20 - 1208f25f6e25499a3a03ccaec74967f97cb89149 Free Fire CDHash SHA1 - d9cf9ae60f2433bf47fe33a29d7122bb1bcc5965 UnityFramework CDHash SHA256-20 - 6eccef487246d3f8e55d5abb0b34a6d47c3c02e7 h function return that needs to be hooked so it will be App Store identified - 00770007d45fe15664db57df30274f5c49daaa04f276be030f20686e673c833b MD5(com.dts.freefireth_98573T3W6L) - 75ead73659249cdb3a0eee33e86c003a 2. What Garena actually bans on? local ui -> Using a modifier -> Calls -> POST https://gin.freefiremobile.com/ios/d...rtIosPv/create plus App Attest A debugger (P_TRACED) can also be a modifier ban for some reason �� Do not hook GOT libc. Fairguard loads GOT._syscall / _dlsym and checks function bytes (+4 == 0x31, +7 == 0x91) plus CFF checker at offset 0x9457f6c (34 callers). Replacing GOT or software-BPing results in a modifier ban. CGP Crypto (login / clientbp bodies) HTTP bodies for MajorLogin / Ping / CheckHack / etc. are not raw protobuf on the wire. They are: AES-128-CBC PKCS7 KEY Yg&tc%DEuh6%Zc^8 IV 6oyZDr22E3ychjM% Implemented in GCommon.HttpManager::Encrypt at offset 0x6bb2c2c. Plaintext is an IL2CPP byte[] in x1 (length +0x18, payload +0x20). CCCrypt never sees the 688/704/432 sizes because Encrypt already produced ciphertext (all sizes 16-multiples). 3. Who actually calls Encrypt CreateRequest - 0x7452768 - Logs LR at 0x745276c HttpManager.CreateRequest - 0x6bb64fc - Logs LR at 0x6bb6500 Vtable slot for Encrypt at 0xbab3db0. A vtable blr would produce a different LR theoretically but It did not. Live log (veneer preserves original x30 with B, not BL): ENCRYPT lr=745276c Call chain for MajorLogin: COW.UIModelLogin::RequestLogin 0x462fa58 new proto.Login.GNBLGPDAPEF 0x3f5dac0 CreateLoginReqInfoData 0x4630910 bl generic RequestPost 0x745385c @ 0x462ff18 (Empty, w5=2) bl generic RequestPost 0x745385c @ 0x46301bc (MajorLogin, w5=4) OverrideChannel 0x6bb2558 generic CreateRequest 0x7452410 @ 0x7453940 bl Encrypt 0x6bb2c2c @ 0x7452768 ← live LR 0x745385c is generic HttpManager.RequestPost (pointer 0). Same wrapper is used by RequestGenerateNickname, RequestPlatformRegister, RequestSetNewbieVeteranChoose. Non-generic RequestPostStream 0x6bb60d0, UGC BLs 0x52b18c8, 1cfc, 20d4 never ran for MajorLogin. Inside 0x7452410, w23 is reqDataType: - 1 - protobuf helper 0x74d0a48 @ 0x7452670 - 2 - LitJson.JsonMapper::ToJson 0x1e9e994 @ 0x7452708 - else - skip serialize, Encrypt existing req.Data RequestLogin passes w7=0, so rdt is loaded from HttpManager+0x30. 4. MajorLogin protobuf Decrypted body around 687–696 bytes (icl I don’t remember). Field 22 - b2 01 20 + 32 ASCII hex - Not team MD5. After Empty RequestPost, RequestLogin stores GarenaMSDKMgr +0x38 at proto +0xa8. This is an MSDK token. Field 29 - ea 01 40 + 64 ASCII hex - Not __TEXT SHA256. GarenaMSDKMgr +0x40 -> proto +0xe0. MSDK token. Changes every new guest. Field 94 - f2 05 48 + 72 ASCII base64 - GOP token. Decode = 52 bytes: magic 2aab074f + 48-byte MAC (HMAC-SHA384-shaped). FairGuard gets the data from MANGENBPGKL lands at proto +0x220 and is only 14 bytes (fP@@$DXUq…), not a SHA256. 5. CheckHackBehavior POST https://clientbp.ppmainecoonghj.com/CheckHackBehavior Built in COW.UIModelSkinModCheck::RequestHackerWarningInfo 0x48e08cc. CSCheckHackBehaviorReq has one field: client_info = MatchClientInfo. proto (after GGP decrypt): Field 1 - tpsdk_str - iOS uid Field 2 - start_time - varint Field 3 - file_exception - XOR via GCommon.Checker.COIFGGAINCK::PEPHNHOLMAK 0x6ce9e24 with uid decimal as repeating key Field 4 - lib_result - same XOR, and it’s 13 bytes Field 6 - scan_count - on sim. It was 11 Field 7 - native_result - same as field 4 Field 8 - client_version - 1.132.11 Field 9 - channel_type - 3 Field 10 - architectual_type - 1 No GOP on this packet server replies empty (n=0). PEPHNHOLMAK is literally: Code: out[i] = data_utf8[i] XOR key_utf8[i % keylen] Key for f3 was the decimal uid (18746603516), not the IOS… prefix. 6. FairGuard score / gin report Score object getters 0x9711d80–0x97121bc. JSON keys (decrypted strings): nRoot, nSimu, nAccel, nDebug, nModify, nRepack, nResign, thSigMatch, defense. Gin POST: https://gin.freefiremobile.com/ios/d...rtIosPv/create JSON: jb, fg_ver, ig1, ig2, pid, h, path, s, bd, cpu, sv, gv, dm, gm, cd plus the n* flags. h is SHA256 of __TEXT. Sending the live patched TEXT hash as h is a ban. Official h is the constant above. FairGuard cmds: 0xf2 0xf3 0xf4 0xf6 0xf9 0xfa - app attest 0xed 0xee 0x79 0x7b 0x7c - attest adjacent 0x65–0x70 - native probes Skipping 0x65 and 0x70 results in a lobby stuck game 7. Provision / CD / team FairGuard compares: - TeamName / Entitlements / application-identifier via CFDictionary (0xa19ce40 and 0xa19ce10). AND PLEASEE DO NOT replace the CFString object with a new NSString, calls JSON builder at `0x9289a94` then executes that object (EXC_BAD_ACCESS). - On-disk Mach-O %@/Frameworks/UnityFramework.framework/UnityFramework. - CC_MD5 of com.dts.freefireth_<TEAM> (29 bytes) at 0x9381f90.
