Brute force an XOR encrypted file with single byte key. This challenge reflects genuine security weaknesses seen in real Kubernetes deployments: Given a Python encryption program, create the program which decrypts the file. from hashlib import sha256 from Crypto.Cipher ... Uses fls and mactime to create a forensic timeline. icat allows us to view the contents of the identified file. Unpack an executable with upx (don't snap install upx, instead apt-get install upx-ucl), reverse engineering in Ghidra, then use ... Grab RSA private key from JPEG comment and decrypt a file with it.
The following Python program connects to the server, gets the hex bytes of an executable, disassembled it and looks for where the ... Use pwntools to read symbols from ELF file and send function addresses to server. Uses Sleuth Kit from SANS SIFT Workstation (you can download separately and not use a VM) to create a timeline and then view ... Use virt-ls and virt-copy-out to extract a GIT repo from a disk image, then git log. Answer questions about a vulnerable program with a stack buffer overflow. Use Ghidra to reverse engineer the encoding of the flag.
