DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN 7 | ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS 8 | INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES 9 | REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS 10 | PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM 11 | THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED 12 | HEREUNDER. 13 | 14 | Statement of Purpose 15 | 16 | The laws of most jurisdictions throughout the world automatically confer 17 | exclusive Copyright and Related Rights (defined below) upon the creator 18 | and subsequent owner(s) (each and all, an "owner") of an original work of 19 | authorship and/or a database (each, a "Work"). 20 | 21 | Certain owners wish to permanently relinquish those rights to a Work for 22 | the purpose of contributing to a commons of creative, cultural and 23 | scientific works ("Commons") that the public can reliably and without fear 24 | of later claims of infringement build upon, modify, incorporate in other 25 | works, reuse and redistribute as freely as possible in any form whatsoever 26 | and for any purposes, including without limitation commercial purposes. 27 | These owners may contribute to the Commons to promote the ideal of a free 28 | culture and the further production of creative, cultural and scientific 29 | works, or to gain reputation or greater distribution for their Work in 30 | part through the use and efforts of others. 31 | 32 | For these and/or other purposes and motivations, and without any 33 | expectation of additional consideration or compensation, the person 34 | associating CC0 with a Work (the "Affirmer"), to the extent that he or she 35 | is an owner of Copyright and Related Rights in the Work, voluntarily 36 | elects to apply CC0 to the Work and publicly distribute the Work under its 37 | terms, with knowledge of his or her Copyright and Related Rights in the 38 | Work and the meaning and intended legal effect of CC0 on those rights. 39 | 40 | 1. Copyright and Related Rights. A Work made available under CC0 may be 41 | protected by copyright and related or neighboring rights ("Copyright and 42 | Related Rights"). Copyright and Related Rights include, but are not 43 | limited to, the following: 44 | 45 | i. the right to reproduce, adapt, distribute, perform, display, 46 | communicate, and translate a Work; 47 | ii. moral rights retained by the original author(s) and/or performer(s); 48 | iii. publicity and privacy rights pertaining to a person's image or 49 | likeness depicted in a Work; 50 | iv. rights protecting against unfair competition in regards to a Work, 51 | subject to the limitations in paragraph 4(a), below; 52 | v. rights protecting the extraction, dissemination, use and reuse of data 53 | in a Work; 54 | vi. database rights (such as those arising under Directive 96/9/EC of the 55 | European Parliament and of the Council of 11 March 1996 on the legal 56 | protection of databases, and under any national implementation 57 | thereof, including any amended or successor version of such 58 | directive); and 59 | vii. other similar, equivalent or corresponding rights throughout the 60 | world based on applicable law or treaty, and any national 61 | implementations thereof. 62 | 63 | 2. Waiver. To the greatest extent permitted by, but not in contravention 64 | of, applicable law, Affirmer hereby overtly, fully, permanently, 65 | irrevocably and unconditionally waives, abandons, and surrenders all of 66 | Affirmer's Copyright and Related Rights and associated claims and causes 67 | of action, whether now known or unknown (including existing as well as 68 | future claims and causes of action), in the Work (i) in all territories 69 | worldwide, (ii) for the maximum duration provided by applicable law or 70 | treaty (including future time extensions), (iii) in any current or future 71 | medium and for any number of copies, and (iv) for any purpose whatsoever, 72 | including without limitation commercial, advertising or promotional 73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each 74 | member of the public at large and to the detriment of Affirmer's heirs and 75 | successors, fully intending that such Waiver shall not be subject to 76 | revocation, rescission, cancellation, termination, or any other legal or 77 | equitable action to disrupt the quiet enjoyment of the Work by the public 78 | as contemplated by Affirmer's express Statement of Purpose. 79 | 80 | 3. Public License Fallback. Should any part of the Waiver for any reason 81 | be judged legally invalid or ineffective under applicable law, then the 82 | Waiver shall be preserved to the maximum extent permitted taking into 83 | account Affirmer's express Statement of Purpose. In addition, to the 84 | extent the Waiver is so judged Affirmer hereby grants to each affected 85 | person a royalty-free, non transferable, non sublicensable, non exclusive, 86 | irrevocable and unconditional license to exercise Affirmer's Copyright and 87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the 88 | maximum duration provided by applicable law or treaty (including future 89 | time extensions), (iii) in any current or future medium and for any number 90 | of copies, and (iv) for any purpose whatsoever, including without 91 | limitation commercial, advertising or promotional purposes (the 92 | "License"). The License shall be deemed effective as of the date CC0 was 93 | applied by Affirmer to the Work. Should any part of the License for any 94 | reason be judged legally invalid or ineffective under applicable law, such 95 | partial invalidity or ineffectiveness shall not invalidate the remainder 96 | of the License, and in such case Affirmer hereby affirms that he or she 97 | will not (i) exercise any of his or her remaining Copyright and Related 98 | Rights in the Work or (ii) assert any associated claims and causes of 99 | action with respect to the Work, in either case contrary to Affirmer's 100 | express Statement of Purpose. 101 | 102 | 4. Limitations and Disclaimers. 103 | 104 | a. No trademark or patent rights held by Affirmer are waived, abandoned, 105 | surrendered, licensed or otherwise affected by this document. 106 | b.

Affirmer disclaims responsibility for clearing rights of other persons 114 | that may apply to the Work or any use thereof, including without 115 | limitation any person's Copyright and Related Rights in the Work. 116 | Further, Affirmer disclaims responsibility for obtaining any necessary 117 | consents, permissions or other rights required for any use of the 118 | Work. 119 | d. Affirmer understands and acknowledges that Creative Commons is not a 120 | party to this document and has no duty or obligation with respect to 121 | this CC0 or use of the Work. 122 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # hacking-docs 2 | Hacking Reference Documentation 3 | -------------------------------------------------------------------------------- /mobile/android-add-frida-gadget.md: -------------------------------------------------------------------------------- 1 | 2 | ## Get APK from device over adb 3 | 4 | find apk file on device: 5 | ``` 6 | adb shell 7 | pm list packages -f | grep -i 8 | ``` 9 | 10 | pull apk file from device: 11 | ``` 12 | adb pull 13 | ``` 14 | 15 | ## unpack and modify APK to add frida libgadget 16 | 17 | 18 | unpack apk with apktool: 19 | ``` 20 | apktool d -o unpack app.apk 21 | ``` 22 | 23 | download frida gadget native lib + extract and rename: 24 | ``` 25 | cd unpack/lib/arm64-v8a 26 | wget https://github.com/frida/frida/releases/download/16.1.5/frida-gadget-16.1.5-android-arm64.so.xz 27 | unxz frida-gadget-16.1.5-android-arm64.so.xz 28 | mv frida-gadget-16.1.5-android-arm64.so libfrida-gadget.so 29 | ``` 30 | 31 | find LAUNCHER activity in manifest: 32 | ``` 33 | TODO 34 | ``` 35 | 36 | search for LAUNCHER activity smali code: 37 | ``` 38 | TODO 39 | ``` 40 | 41 | look for the following method: 42 | ``` 43 | .method public constructor ()V 44 | ``` 45 | 46 | add the following smali code to the above constructor: 47 | ``` 48 | const-string v0, "frida-gadget" 49 | invoke-static {v0}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V 50 | ``` 51 | 52 | 53 | add to manifest application element: 54 | ``` 55 | android:usesCleartextTraffic="true" 56 | android:extractNativeLibs="true" 57 | ``` 58 | 59 | ## Generate a JKS for APK signing 60 | 61 | run keytool to generate java keystore (JKS) for apk signing: 62 | ``` 63 | keytool -genkey -v -keystore custom.keystore -alias mykeyaliasname -keyalg RSA -keysize 2048 -validity 10000 64 | ``` 65 | 66 | ## Repackage APK 67 | 68 | repack APK: 69 | ``` 70 | apktool b --use-aapt2 -o mod-app.apk unpack/ 71 | ``` 72 | 73 | zipalign APK: 74 | ``` 75 | zipalign 4 mod-app.apk final-mod-app.apk 76 | ``` 77 | 78 | sign APK file with JKS: 79 | ``` 80 | apksigner sign -ks custom.keystore final-mod-app.apk 81 | ``` 82 | 83 | ## Install APK to phone 84 | 85 | install APK with adb: 86 | ``` 87 | adb install final-mod-app.apk 88 | ``` 89 | 90 | ## Frida scripts for bypass pinning 91 | 92 | Sometimes one of these scripts will fail for some reason. 93 | 94 | frida ssl bypass scripts: 95 | ``` 96 | frida -U gadget --codeshare akabe1/frida-multiple-unpinning 97 | frida -U gadget --codeshare sowdust/universal-android-ssl-pinning-bypass-2 98 | ``` 99 | --------------------------------------------------------------------------------
