base on LKM rootkit for Linux Kernels 2.6.x/3.x/4.x/5.x/6.x (x86/x86_64 and ARM64) Diamorphine =========== Diamorphine is a LKM rootkit for Linux Kernels 2.6.x/3.x/4.x/5.x/6.x (x86/x86_64 and ARM64) Features -- - When loaded, the module starts invisible; - Hide/unhide any process by sending a signal 31; - Sending a signal 63(to any pid) makes the module become (in)visible; - Sending a signal 64(to any pid) makes the given user become root; - Files or directories starting with the MAGIC_PREFIX become invisible; - Source: https://github.com/m0nad/Diamorphine Install -- Verify if the kernel is 2.6.x/3.x/4.x/5.x ``` uname -r ``` Clone the repository ``` git clone https://github.com/m0nad/Diamorphine ``` Enter the folder ``` cd Diamorphine ``` Compile ``` make ``` Load the module(as root) ``` insmod diamorphine.ko ``` Uninstall -- The module starts invisible, to remove you need to make it visible ``` kill -63 0 ``` Then remove the module(as root) ``` rmmod diamorphine ``` References -- Wikipedia Rootkit https://en.wikipedia.org/wiki/Rootkit Linux Device Drivers http://lwn.net/Kernel/LDD3/ LKM HACKING https://web.archive.org/web/20140701183221/https://www.thc.org/papers/LKM_HACKING.html Memset's blog http://memset.wordpress.com/ Linux on-the-fly kernel patching without LKM http://phrack.org/issues/58/7.html WRITING A SIMPLE ROOTKIT FOR LINUX https://web.archive.org/web/20160620231623/http://big-daddy.fr/repository/Documentation/Hacking/Security/Malware/Rootkits/writing-rootkit.txt Linux Cross Reference http://lxr.free-electrons.com/ zizzu0 LinuxKernelModules https://github.com/zizzu0/LinuxKernelModules/ Linux Rootkits: New Methods for Kernel 5.7+ https://xcellerator.github.io/posts/linux_rootkits_11/ ", Assign "at most 3 tags" to the expected json: {"id":"5857","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
