Hello everyone!
July is here and Fourth of July festivities are about to launch. And what would a holiday weekend be without a new set of challenges so you can enjoy a different kind of fireworks?
In honor of the Fourth, there are four challenges, each one of a different type. Fourth of July, four challenges, four types of challenges… You get the idea.

Hello everyone!
Whew! Last week at WWHF Way West was an absolute blast! And MetaCTF brought their “A” game, as usual!
If you didn’t get enough CTF excitement last week, or if you just feel like challenging your paraskevidekatriaphobia (fear of Friday the 13th), this week we are releasing four reverse engineering challenges for your enjoyment.

Hello everyone!
This week we’re back to the usual number of challenges being released, and they are all slightly different flavors. There’s a little bit of recon, a dash of crypto, some reverse engineering, with forensics on the side. Yum!

Hello everyone!
Although February is the shortest month of the year, this week’s release has a little something extra for you. Normally, we try to release four challenges at a time, but this week we’re serving up five for your hacking pleasure! There isn’t a specific theme, just a nice mix of exploits that are on the challenging side to help keep you warm on a chilly day (or night).

Hello everyone!
If you enjoyed our last release, you will probably like this week’s, too. Most of this week’s challenges also have to do with reverse engineering software, but this time using Python rather than Assembler. As an added attraction, though, the fourth challenge will test your sleuthing skills to find where a specific photograph was taken.
The image you need to investigate relates to specific events during the civil rights movement in the 1950s, and, in honor of Black History Month, we encourage you to use this challenge to not only figure out where the photo was taken so you can get the points but as an opportunity to learn a bit about the political and social events of those times.

Hello there, you happy hacker folk!
As promised, this week we are decidedly NOT taking it easy on you. For this week’s release, we have three related reverse engineering challenges, plus a web exploitation problem. The first reverse engineering problem is the easiest. From there, we crank things up to 11.

Hello and Happy New Year!
We hope your holidays were filled with all good things, and to get the New Year off to a good start, we thought we would take it a little bit easy on you for the first challenge release of the year. This week’s release has some forensics, some web exploitation, and some cryptography for spice. But don’t think we’ll take things easy on you for long. We have some goodies in the queue guaranteed to make your skull sweat! 😆

Hello everyone!
As you may have heard, the Cyber Range has a new home and is now being hosted by MetaCTF. We took a little extra time to let the dust settle, but now we’re confident that the Ts and crossed and the Is are dotted, and it’s time to release a new batch of challenges for you.
This week we have four new opportunities for you to explore the world of binary exploitation, so fire up your reverse engineering tools and dive in!

Hello everyone!
Halloween is this coming Sunday, October 31, and this week’s release of challenges is a special treat with an assortment of flavors for your fun and entertainment. We have hashes and matrices and algorithms. The flavors run the gamut from crypto to web exploitation. And we threw in an extra challenge, so this week you get six shiny new additions instead of the usual five. We like to think of it like we’re giving out full sized candy bars instead of the smaller, “fun-sized” treats.

Hello everyone!
Did you know that October 15th was National Grouch Day? The good news is that unlike Oscar’s choice in décor, this week’s challenges aren’t garbage! No offense to the Number 1 grouch on Sesame Street but they do live in a trash can, after all.
This batch of freshly baked pumpkin spice challenges is heavy on the forensics, with some cryptography and web exploitation fun for added variety and flavor.

Hello everyone!
The last batch of challenges were a little bit more challenging than usual, so this time around we are releasing some easy ones to make up for it. This week’s challenges are worth 250 points each or less, but that doesn’t mean they won’t make you stop and think. Don’t forget, even simple mistakes can still throw a wrench into the works.

Hey folks,
This week’s batch of challenges is a bit tougher than usual. Every single challenge in this week’s release has a point value over 350, which means they are all extra tricky and guaranteed to make your skull sweat. They are all either reverse engineering or forensics problems, as well, which might seem to some to be unfair, or cruel, or just plain mean, but we have faith that you are up to the task. Now go out there and show us what kind of hacking rockstar you are!

Hey folks,
As you probably know already, Memorial Day is an American holiday observed on the last Monday of May which honors the men and women who died while serving in the U.S. military. All that business with BBQs and picnics all weekend long isn’t really what the holiday is about.
Since you likely have a long holiday weekend ahead of you, we decided to release some challenges that are a bit more “challenging”… just to keep you busy!
This week’s release is mostly about reconnaissance, but we threw in some reverse engineering and some math fun, just for spice.

Hey folks,
This week’s challenges are mostly about cryptography. Test your mettle against some seemingly simple Base64 encoding, find the extras embedded in a well-known passage that has been used by typesetters since the 1500s, and help out some poor folks who thought building their own encryption system was a good idea. Fun times!

Hey folks,
The latest batch of newly released Cyber Range challenges touch on topics relevant to John Strand’s upcoming “SOC Core Skills” class. This is a very popular class that introduces people to key fundamentals used by security operations center (SOC) analysts. To get you thinking like a SOC analyst, this week’s challenges will test your skills at analyzing web server logs and PCAP files and at figuring out how to analyze files that are not exactly what they seem to be.

Howdy folks,
This week the Cyber Range is pleased to release a collection of challenges that tackle everything from crypto to Kerberoasting! We tried to wrassle up some problems to coincide with Darin and Carrie Roberts’ class about Atomic Red Team and other really cool attack emulation tools, but rustling those challenges was more like bronco bustin’! Score 1 for the broncos.
Not to fear! The latest batch of challenges has a little something for everyone, and we’ll keep working to corral those other varmints just as soon as we can. Until then, set your sights on these rascals. You can find screenshots and descriptions of the new critters below.

Howdy folks,
This week we are releasing five new Cyber Range problems to coincide with Kent Ickler and Jordan Drysdale’s Applied Purple Teaming training course, which started on February 2. We specifically picked problems that relate to some of the concepts and issues they cover, including the MITRE ATT&CK framework, PowerShell exploits, and enterprise OSINT awareness. You can find screenshots and descriptions of the new problems below.
These new problems are just the latest ones we’ve released. More are in development as this goes to press, so stay tuned for the challenges yet to come.

FIVE NEW PROBLEMS ADDED TO CYBER RANGE
Recently, the Cyber Range team added five new problems to the Cyber Range.
The first challenge addition is part 3 of the “Python Login Pannel” from the previous updates. In this challenge, the user is told that the web developer has gotten “smarter” and sets the challenge of gaining access once more.
The next challenge to be added is titled “Ransomeware Attack Part 1” and it tasks the user with trying to find out who is behind an “attack” on C3’s system by finding where the intruder hosted their ransomware from and finding a flag in the process.
Tune in next week for part 2 of this challenge!
The third challenge addition tasks the user with trying to get access to private API’s without paying for a subscription using a documentation for an API that only gives public API’s.
The fourth challenge asks the user to find “interesting things” within a “colorful” page in order to find the flag.
The fifth and final addition asks the user to help “read” a message that was typed up by a “friend” using a weird font.
Last but not least, the CyberRange team has created a challenge seeking the users feedback! The link to the “Feedback Survey” can also be found below!
You can find the survey here:
