I am stuck on the "OWASP 2017 Java: Underprotected APIs" challenge. I have tried accessing "<Target URL>/FileDownloadServlet?path=/etc/&file=flag.txt," for which I received the error message "HACKING DETECTED! Your activity has been logged, and authorities have been informed." I created a user with admin privileges and used its session to access the above-mentioned URL, but that also didn't work.Solved186Views2likes1CommentPowershell Deobsfuscation Ep.7
I was working on this and got stuck with Ep.7. Appreciate if anyone can assist with this Powershell de-obfuscation. Step 1: I removed the splits accordingly and converted from hexadecimal Step 2: Next, there was another set of splits to perform and ascii conversion. Ended up with the small snip of string at the bottom with a lot of (spaces and tabs) at the beginning. Basically empty spaces before coming to this short scripts. I am not sure on how to move from here. Anyone can assist with this pls?Solved210Views2likes7CommentsAnyone finished the "Etherium Smart Contracts"?

I'm stuck at below two questions Q6: Which variable does the initial script try to return? Q8: The exploit kit contains a large block of hex encoded shellcode stored in a variable. This shellcode is also XOR encoded. What is the single byte xor key? (In the format 0xNN e.g. 0x11.) So far I downloaded the HTTP objects via Wireshark, extracted the script to JSDetox then decoded base64 strings which resolves to other 2 scripts. With these steps I was able to answer other questions but I can't go any further, any guidance? Thanks in advanceSolved396Views1like10Comments
