Hello all! It has been some time since my last post, so I thought I’d write about something fun that I came across!
Return of The Penguin is the first reversing challenge from B-Sides London 2016, brought to us by the creator of last year’s Toxic PDF. In this challenge we are given an unknown binary and a number of guiding questions to answer!
It has been some time since I’ve posted anything, so I thought I’d look at the Android crackmes posted by DefendIO (link)! The link to the crackmes has got a number of challenges, of different levels. There are a lot of starter challenges (level 1), a level 2 and a level 4 challenge!
This is the writeup of the level 2 challenge, called ‘jumbled cme’!
I attended BSides London and, after it was done and over, I found out they had challenges! So I found some time to play with one of them, toxic_pdf! It has been a while since my last PDF challenge, so let’s give this a go!
This challenge is also themed, but more on this in a bit!
Ghastly grim and ancient raven wandering from the nightly shore –
Tell me what thy lordly name is on the Night’s Plutonian shore!’
Quoth the raven, `Nevermore.’
Hello and welcome to Part 3 of the FLARE-ON challenges (here are parts 1 and 2 in case you need to catch up!) This challenge started with the following message:
Nice job, you’re really knocking these out! Here’s the next binary. The password to the zip archive is “malware” again.
Keep up the good work, and good luck!
By the way get used to this; the password will be ‘malware’ for the future zips. There’s nothing in this welcoming message that hints to what we should do for this level (like in the previous one for example), so off we go!
