+# Solution
+When the apk is loaded in Android Studio, we can see the decompiled smali code. This shows the long line of base64 being loaded as a dex file. We can also see `getFlag` loaded using `getMethod`. However the flag is not shown anywhere in this class.
+
+There are several ways to approach this but I believe the simplest way is to decode the string and save it as a file. (The inspiration for the chal was to use FRIDA to get the file, but this seems easier 🫠) Once the DEX file is saved, it can be decompiled and the url of the python server is revealed. The python server sends a big b64-encoded blob, which is saved to the `notTheFlag` var in the local scope. The `obf` function is used to pull the flag out using the right xor key. This prevents players from just getting the blob from the server and decoding it. To get the flag players can reverse the `obf` function or patch the decompiled dex.
+
+A patched version of the decompiled dex is provided (`Dropped.java`)
+
+
+## Testing Notes
+This chal is not too difficult, just takes some reading on Android reversing. It can be made harder by using the `obf` function to also build the dex file manually, which I believe the code in the [original blogpost](https://www.eff.org/deeplinks/2022/04/anatomy-android-malware-dropper) is doing. This can be built from resources, hidden in images, etc. I can also add some red herrings but I noticed some players did not enjoy when I did that last year.
+
+To build / run docker:
+```
+docker build -t android-dropper .
+docker run -dp 3003:3003 android-dropper
+```

+# Linear Aggressor
+Category: misc
+Difficulty: Easy
+
+
+## Description
+This a model extraction challenge where the player needs to extract the weights of the model in order to get the flag.
+
+
+## Deployment
+You can use docker to deploy the challenge. It is hosted on an Ubuntu image
+`docker build`
+`docker`
+
+
+## Flag
+csawctf{m0d31_5t341ing_i5_b4d}
+
+
+## Solution
+Linear Regression is a model that takes the sum of a constant and dot product of the weights and the inputs.
+
+
+To steal this model the adversary needs to set all the inputs to 0 to get the constant value *b*.
+To retrieve the first weight of the model, set the first input to 1 and the rest to be 0 and subtract b.
+Repeat for second to the end. Convert weights to ascii to get the flag.

+If you look at the stack in the function, there's 0x2c bytes reserved for the parameter that gets passed to fgets, but it gets 100 bytes of input.
+
+Because of this, if you provide more than 2c bytes of input, you overwrite the next variable on the stack - the one that determines if the flag prints or not.
+
+So just send a bunch of 'A's!

+# Unlimited Subway
+
+Unlimited Subway is a pwn challenge focused on bypassing canary in 32-bit environment.
+
+The binary has an arbitrary read vulnerability in view_account method that prints an arbitrary index of account info. This can be used to reveal the contents of canary.
+
+Choice "Fill account info" can't really be used to do anything but to fill the account buffer. However, choice "Exit" reveals a way to set the length of the following input which can be used to trigger buffer over flow. With a well crafted payload, one can overwrite the return address to print_flag method to print the flag of the challenge.
+
+# Solution
+
+There are two parts to the solution.
+
+The first part is to leak the canary by taking advantage of the infinite loop of the program.
+
+After leaking the canary, one can supply the payload composed with dummies, canary, and the return address to solve the challenge.
+
+The intended solution can be found at [folder][1]
+
+Run `python3 solution.py` to solve.
+
+
+[1]: ./solution
