CyberPaws CTF: Week 13
Baby's First BinBomb
The next CyberPaws CTF challenge has been released! Please submit your flag to the "Prize Pup Bot" on our Discord via DMs, using the `!submit` command! You have until our next meeting to submit. The flag will always be in the following format: Paws{ex4mpl3_fl4g}.
Category: Binary Exploitation
Challenge Name: Baby's First BinBomb
If you're new to binary bombs, this is the perfect start!
Your task is to defuse a ticking time bomb by entering the correct input into the command line of a Linux terminal. If the correct input is provided, the bomb diffuses. If not, it explodes!
Run the binary in a Linux terminal, play the game, and solve the questions to get the flag.
There are two paths: You can try to solve the puzzles and guess your way to safety, or you can dive into the code and figure out the expected inputs before ever running the program
Whether you're a codebreaker or a puzzle solver, this challenge has something for everyone. Good luck and have fun!
Note: The flag will be alphanumeric. Please surround it with Paws{} when submitting, like so: Paws{ex4mpL3_fl4G}

CyberPaws CTF: Week 12
More Scodes!
The next CyberPaws CTF challenge has been released! Please submit your flag to the "Prize Pup Bot" on our Discord via DMs, using the `!submit` command! You have until our next meeting to submit. The flag will always be in the following format: Paws{ex4mpl3_fl4g}.
Category: Audio/Video
Challenge Name: More Scodes!
We got something strange and unusual.
A weird transmission sent by a suspected threat actor went out on a UHF radio band. We've saved it to this audio file and now we need you to analyze it.
The transmission seems almost like there's some pattern to the beeping noises that can be heard on the frequency, but we need you to figure out exactly what.
Can you analyze this audio/video and extract the information?
Note: The flag will be alphanumeric and upper case only. Please surround it with Paws{} when submitting, like so: Paws{TH1SEX4MPL3FLAG}

If you've enjoyed attending the meetings and want them them to continue, please think about applying for these position. If we do not fill these positions, we can not operate as a club.
You can apply using the nomination form link below:

Category: Forensics
Challenge Name: Grep Analysis
We recovered data about a hardware dump from a network transfer between a suspicious IP and a known cyber-criminal.
We know that the cyber-criminal was at a specific Starbucks, but there are so many people there on laptops in the security footage that we can't tell which one is him. To make matters worse, the traffic has been proxied so we can't determine the IP info for the device either.
Because threat actors tend to have preferences for software, we think getting the product name used for the hardware dump can help us narrow it down.
Can you figure out the product name from this hardware dump?
Note: The flag will be the alphanumeric name of the software, in all capitals and no spaces. You will need to surround it with Paws{} before submitting it, like so: Paws{PRODUCTNAME50}

Proposed Club Constitution Revisions
Please Review Proposals | Vote at NOV 27 Club Meeting
Hey CyberDawgs,
Over the last couple of months, the Board has been working together to create a Revised Club Constitution that address key missing elements of our current one. At this time, we are excited to finally share with you our planned final draft for your approval.
Proposed Revised Club Constitution
For Reference, our Current Club Constitution
As in accordance of Article V of our club's current constitution, any amendments/changes must be approved by a 2/3 vote of all members present at a meeting. This approval vote will take place at the beginning of our November 27th club meeting. Furthermore, we will be the taking time at the end of our November 20th meeting to review the revisions and answer questions.
Questions/Concerns?
If you have questions or concerns about the revised club constitution, don't hesitate to send me a message or email. [Discord: @truegritter] [Email:
wbrooks1@umbc.edu]. Furthermore, feel free to ask questions in the general chat at any time on our Discord.
Kind Regards,
William Brooks
CyberDawgs President
Hey CyberDawgs,
Below is Information on the team tryouts, coming to you December 1st & 2nd
First, here is the Team Application Form (must fill out prior to arrival):
And the Team/Tryout Information Slides:
Overview:
As a team, the CyberDawgs participate in numerous collegiate cyber competitions where we have achieved national recognition, including DOE CyberForce in Illinois, ISTS in New York, and MACCDC right here at home in Maryland.
While we have a history of success and high achievement, we're not just looking for folks who are already cybersecurity gurus. You do need to have a solid defensive cyber foundation, but our highest emphases are on communication, group cohesion, and being able to continue doing this for fun.
When/Where
- ENG 231 (probably)
- Friday, 01 DEC, 12:00 - 15:00
- Saturday, 02 DEC, 12:00 - 15:00
You only need to select 1 of these dates/times above to tryout.
Preparing for Tryouts
At the tryouts, you'll be assessed on your defensive cyber capabilities and knowledge as well as your documentation, interpersonal, and communication skills. The tryout packet, available only at the tryouts, will provide more information.
To prepare, focus on learning and reviewing:
- what constitutes a cyber security vulnerability
- how to secure an operating system (i.e. a 'box') that is vulnerable
- how to manually find indicators of compromise, after an assumed breach
You do not need to know a suite of tools for tryouts. You will not be given tools, aside from Nmap.
Tryout FAQs
What OS do I need to know?
- You'll be asked in the application which type of OS you're most comfortable with and you'll be assigned a similar box to that for tryouts. So, if you indicate you're most familiar with Windows, you'll get a Windows server at tryouts. Linux people get a Linux server. You will only have to manage 1 machine.
Will there be a technical interview? No
Will I be asked coding questions? No
Will I need to know offensive security? No
Will I need to bring my own laptop? YES
Will I be able to keep the tryout packet? No
Tryout Preparation Resources
Below is some important information to consider for tryouts:
- Recall that you will be assigned a virtual machine for tryouts. Which one you get is determined by your answer to the question "With which operating system are you most experienced?" When considering your answer to that question, consider that it is asking about experience in system administration, digital forensics, incident response, and general usage. This is a cybersecurity team tryouts. Keep that in mind.
- The virtual machine you will be assigned for tryouts doesn't use your local resources. Therefore, the specs of your personal laptop hardly matter. Bring and use whatever laptop with which you feel most comfortable
- The only requirement of the laptop you bring to tryouts is that is has RDP (only if you choose Windows), SSH (only if you choose Linux), and a WIFI adapter, because you need to be able to get on the tryout network via WIFI.
- It would probably help you to have Discord installed, though
- If your laptop has a Windows 'home' operating system, you might not natively have RDP. If you choose Windows as your tryout box, you will need RDP. Try this: https://apps.microsoft.com/detail/microsoft-remote-desktop/9WZDNCRFJ3PS?hl=en-gb&gl=GB
Final Thoughts
As always, my door remains open and I welcome hearing from you. If you have questions, comments, concerns or just want to check in, please feel free to send me a message. [@_nuevo on Discord]
Kei-Won-Tia,
CyberDawgs Vice President, Team Captain
