8## Intro into assembly
9Each personal computer has a microprocessor that manages the computer’s arithmetical, logical, and control activities.
10
11Each family of processors has its own set of instructions for handling operations like getting user input, displaying info on screen etc. These set of instructions are called ‘machine language instructions’. A processor can only understand these machine language instructions which is basically 0’s & 1’s. So, here comes the need of our low-level assembly.
12
13Assembly can be intimidating so I will sum it up for you and this is (pretty) enough to start pwning some binaries.
14
15- In assembly you are given 8-32 global variables of fixed size to work with which are called “registers”.
16- There are some special registers also. MOst important is “program counter”, which tells the cpu which instruction we’re executing next. This is same as IP(instruction pointer) - don’t get confused.
17- Technically, all the computation is executed on registers. A 64-bit processor requires 64-bit registers, since it enables the CPU to access 64-bit memory addresses. A 64-bit register can also store 64-bit instructions, which cannot be loaded into a 32-bit register. Therefore, most programs written for 32-bit processors can run on 64-bit computers, while 64-bit programs are not backward compatible with 32-bit machines.
18- But big programs need more space so they access memory. Memory is accessed by using memory location or through push & pop op. on a stack.
19- Control flow is handled via altering program counter directly using jumps, branches, or calls. These inst. are called “GOTOs”.
20- Status flags are generally of 1-bit. They tells about wheather flag is set or reset.
21- Branches are just GOTOs that are predicated on a status flag, like, “GOTO this address only if the last arithmetic operation resulted in zero”.
22- A CALL is just an unconditional GOTO that pushes the next address on the stack, so a RET instruction can later pop it off and keep going where the CALL left off.
23
24I think this is enough info about assembly and you’re ready to dive into binary exploitation. Wanna learn more then this book is awesome - [here](https://beginners.re/RE4B-EN.pdf)
25
26## Let’s start pwning binaries
27To start you will need a disassembler(converts 0’s & 1’s [machine code] into assembly) like radare2, IDA, objdump etc. and a debugger(used to debug programs) like gdb, OllyDbg etc.
28
29Let’s get started: Here is the code that I wrote and we will try to exploit it. It’s a simple license checker which check two strings. Source will be available on my [github](https://github.com/anon6405/binary_exploit).
30
31crackme1.c
32```c
33#include <stdio.h>
34#include <string.h>
35int main(int argc, char *argv[]){
36 if(argc==2){
37 printf("Checking Licence: %s\n", argv[1]);
38 if(strcmp(argv[1], "hello_stranger")==0){
39 printf("Access Granted!\n");
40 printf("Your are 1337 h4xx0r\n");
41 }
42 else{
43 printf("Wrong!\n");
44 }
45 }
46 else{
47 fprintf(stderr, "Usage: %s <name>\n", argv[0]);
48 return 1;
49 }
50
51 return 0;
52}
53```
54
55This code is pretty simple and I hope you can understand it. So lets compile it.
56```shell
57$ gcc crackme1.c -o crackme1
58```
59
60Now we will use gdb to debug our program
61```
62$ gdb crackme1
63```
64
65Now we know that every program has main function. So lets disassemble it.
66```
67(gdb) disassemble main
68```
69
70It will through this:
71```shell

117
118This looks ugly right. Well it’s AT&T syntax, change it to intel using:
119```
120(gdb) set disassembly-flavor intel
121```
122
123For permanent change, create ~/.gdbinit and add
124```
125set disassembly-flavor intel
126```
127
128Again disassemble main and you will get a more readable code

175
176Now make a assumption how this binary works. When you run it without any argument it will display the usage message. If you pass two arguments where first one is program name itself and second one is license key, it will display a access granted or access denied message. Now apply that assumption to assembly code.
177
178For exploitation, we can ignore most of the stuff. So at 0x1178, you can see a cmp function which is comparing a pointer to hex 0x2(which is 2 in decimal). According to our assumption, that must be checking arguments. Just below that 0x117c have a jne(basically jump not equal). So if those strings don’t match, control flow will jump to addr 0x11e3. Now at addr 0x1198, it is calling a printf function, which maybe printing “Checking License:” when you run the binary. Next interesting addr is 0x11b2, it is calling a strcmp(string compare) function. It should be comparing our key with the correct key to verify. Next we have 0x11b7 which is a test function and returns value 0 if strings match. After that we have addr 0x11b9 which is jne(jump not equal), jumps to addr 0x11d5 if strings are not equal. After that we have 0x11c2 and 0x11ce which is calling a puts(it just prints stuff) function, this will print “Access Granted!” and some other text if we give correct key. Next is 0x11d3 which will jump to 0x120c and terminates our program. Now let’s exploit it using gdb to print access granted without using key.
179
180First set breakpoint at main. Breakpoint is a point in memory where your execution stops.
181```
182(gdb) break *main
183```
184
185Now run the program and watch the control flow. You can use pen-paper for better understanding.
186```
187(gdb) run
188(gdb) ni
189```
190
191ni is to execute next instruction. After that just press enter and it will execute the next instruction. Now try running the program with a key.
192```
193(gdb) run random_key
194(gdb) ni
195```
196
197Carefully watch the control flow this time. Now according to our assumption, if we change the value of eax at addr 0x11b7, we are telling the program that the strings matched and it will print the access granted message. So for that set breakpoint 2 to the address of test eax, eax.
198```
199(gdb) disass main
200(gdb) break *0x00005555555551b7
201```
202
203Again run the program with a random_key.
204```
205(gdb) run random_key
206```
207
208After hitting the first breakpoint, type continue to jump to next breakpoint.
209```
210(gdb) continue
211(gdb) info registers
212(gdb) set $eax=0
213(gdb) ni
214```
215
216Here I set the value of eax to 0 and run the program instruction by instruction. After setting eax=0, next addr 0x00005555555551b9 will not be executed as it is jne. Use ni to continue executing next instruction.
217```shell
218(gdb) run random_key

4description: Using dynamic image source for dynamic CSS
5draft: false
6---
7My site uses dynamic css to generate dark or white theme based on user's system theme. So sometimes, I need to use different image colors to fit my needs. There is a very easy fix which involves using javascript but

10
11(well accept for feather icons. i'll add only few icons once i get time.)

13## Using invert color filter in CSS
14```css
15img {
16 -webkit-filter: invert(1);
17 filter: invert(1);
18}
19```
20But sometimes it's just not the right way.
21
22## Using @media
23This is a better approach as it changes the source of the image.
24
25main.css
26```css
27<img class="class_name" src='img_light.png'/>
28```
29
30dark.css
31```css
32@media {
33 .class_name{
34 content: url(img_dark.png);
35 }
36}

2title: "Using Optimus on Void or Non Systemd Distros"
3date: 2019-09-13T12:10:56+05:30

8## What is optimus technology?
9According to gentoo wiki
10> NVIDIA Optimus is a proprietary technology that seamlessly switches between two GPUs. It is typically used on systems that have an integrated Intel GPU and a discrete NVIDIA GPU. The main benefit of using NVIDIA Optimus is to extend battery life by providing maximum GPU performance only when needed.
11
12There is a great wiki about using bumblebee(not transformer) on void linux but bumblebee’s project last commit was in 2013 and it doesn’t support vulkan, so no luck for linux gamers. A better way is to use a utility like nvidia-prime which is available for ubuntu or optimus-manager which is available for arch-based distros(available in AUR). Sadly, these projects require systemd as a init system. There is only one project which uses shell script and partly depends on systemd but is pretty hackable - [nvidia-xrun](https://github.com/Witko/nvidia-xrun).
13
14## Problem on void
15libglvnd is broken in void repos which makes it hard to have multiple drivers from different vendors to coexist on the same filesystem. This results in having either openGL libraries from mesa or nvidia.
16
17## The Hack
18Install nvidia openGL libraries in /opt directory and point nvidia-xrun to use them. This is just a workaround of libglvnd.
19
20First of all install these packages:
21- nvidia-dkms - for kernel modules
22- libGL libEGL - mesa drivers
23- xrandr xorg - display server
24- any wm/de
25
26Create a file /etc/modprobe.d/nvidia.conf for blacklisting nvidia kernel modules so that they won’t be loaded at boot. Add the following text:
27```
28blacklist nvidia
29blacklist nvidia-drm
30blacklist nvidia-modeset
31blacklist nvidia-uv
32blacklist nouveau
33```
34
35Next create some directories
36```shell
37$ sudo mkdir /opt/nvidia
38$ sudo mkdir -p /opt/nvidia/fakeroot/usr/lib
39$ sudo mkdir -p /opt/nvidia/fakeroot/usr/lib32
40$ sudo mkdir /etc/X11/nvidia
41```
42
43Now we have to create a fakeroot directory with nvidia openGL libraries
44```shell
45$ sudo ln -s /opt/nvidia/fakeroot/usr/lib /opt/nvidia/fakeroot/lib
46$ sudo ln -s /opt/nvidia/fakeroot/usr/lib32 /opt/nvidia/fakeroot/lib32
47$ sudo chmod 755 -R /opt/nvidia/fakeroot
48$ xbps-install --rootdir /opt/nvidia/fakeroot --repository https://alpha.de.repo.voidlinux.org/current --repository https://alpha.de.repo.voidlinux.org/current/nonfree --repository https://alpha.de.repo.voidlinux.org/current/multilib --repository https://alpha.de.repo.voidlinux.org/current/multilib/nonfree --yes --sync nvidia nvidia-libs nvidia-libs-32bit
49```
50
51Next clone my repo and move the scripts to respective location
52```shell
53$ git clone https://github.com/fd0e/optimus-hack.git
54$ cd optimus-hack/
55$ sudo cp -r xorg.conf xorg.conf.d /etc/X11/nvidia/
56$ sudo cp run.sh /opt/nvidia/
57```
58
59There is also off.sh which ensures that GPU is off. Run this as root at boot.
60
61Also add these lines in your ~/.xinitrc.
62```shell
63# load additional configs
64if [ "$2" = "nvidia" ]; then
65 XINIT_D="/etc/X11/nvidia/xinit/xinitrc.d"
66else
67 XINIT_D="/etc/X11/xinit/xinitrc.d"
68fi
69
70if [ -d "$XINIT_D" ]; then
71 for f in "$XINIT_D/?*.sh" ; do
72 [ -x "$f" ] && . "$f"
73 done
74 unset f
75fi
76unset XINIT_D
77
78# additional nvidia specific settings
79if [ "$2" = "nvidia" ]; then
80 xrandr --setprovideroutputsource modesetting NVIDIA-0
81 xrandr --auto
82fi
83```
84
85Now close your X session and run /opt/nvidia/run.sh.
86
87And boom! Your X session is now running on nvidia opengl libraries.
88
89## Troubleshooting
90If steam complains about missing libGL. Run steam using this command
91```shell
92$ STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam
93```
94
95## Conclusion
96I don’t recommend using this method but this is the only thing that worked for me.

2title: "My Setup"
3date: 2020-05-19T19:21:39+05:30
4description: Hardware & Software that I use
5draft: false
6---
7## Hardware
8I have one laptop and one PC at home but I only use my laptop [`HP Pavilion 15-au620tx`] as a daily driver. It's a nice machine with a i5-7200U processor, 8 gigs ram and a nvidia 940mx for gaming.
9
10I also have a `Zenfone Max Pro M2`. For listening, I use `Skullcandy Uproar`.
11
12## Software
13![](/images/rice.png)
14
15My software of choice is very minimal. I like things to do what they are supposed to do, nothing less, nothing more. I run gentoo linux with nomultilib/hardened profile. I use suckless software like dwm, st, dmenu, slock to handle my daily needs - if you don't know what they are check them [out](https://suckless.org/). My browser of choice is hardened firefox with tips from [privacytools](https://www.privacytools.io/browsers/).
16
17> You need a bloated browser to browse the bloated web - Luke Smith
18
19Some more tools that I regularly use - `cmus` for music, `bash` as my shell, `zathura` for PDFs, `pass` for managing passwords, `weechat` for IRC, `aerc` for mail.
20
21For pentesting, I use blackarch in virtualbox with just the tools that I need.
22
23## Android
24Coming to my android setup - I use [LineageOS with microG patches](https://lineage.microg.org/) because the name `OpenGApps` is very misleading. My browser of choice for android is [bromite](https://www.bromite.org/) (which is pretty much degoogled chromium). I use [F-Droid](https://f-droid.org/) for installing additional apps. For most of my social media, I use PWAs. I also have [Aurora Store](https://auroraoss.com/) installed just for whatsapp (mostly for my uni groups). Lawnchair is my launcher of choice. Sometimes I do ROM-hoping (i don't even know if that's a thing). To make other ROMs degoogled, I use [nanodroid patches](https://nanolx.org/nanolx/nanodroid) or [minMicrog](https://github.com/friendlyneighborhoodshane/minmicrog_releases/releases).
25
26Some other apps that I use - `K9` for mail, `feeder` for RSS feeds, `Infinity` for reddit, `Revolution IRC` for IRC, `Go Player` for music, `newspipe` for youtube, `OsmAnd` for directions, `PasswordStore` for passwords, `termux` as terminal.
27
28That's it for today, Peace
