“What do you mean the SuperTrains are down and we’ll have to walk?!”
“I mean exactly what I said,” said the headmaster, Mr Rosewood, glaring at the guy who’d shouted. “Please find someone to walk back to your Home with. Whatever you do, don’t walk down there unaccompanied.”
Russian Proverb and Riddle of the Day 2
The solution to the last riddle is… Scissors. Here is today’s riddle: The stallion is running – the Earth is quaking. And now for the saying: It’s at dinner-time you need a spoon. (A bit like: A stitch in time etc.)
Thoughts on Social Media based problem
If we need to search Social media and extract vital information, perhaps the secret is in making best use of the search tools. I don’t use social media, so this is just from a quick glance on the web. Twitter has an advanced search tool which you access at https://twitter.com/search-advanced. Thinking up clever search terms to put into here might be a useful skill. There are tools available to allow you to download the results of twitter searches into the

Data’s thoughts – 2
More ideas from Data Few other windows thoughts: Look in the c:\windows\prefetch folder sometimes malware has a place it runs from, creates a copy of itself somewhere else, runs that, then deletes the copy. Doesn’t always clean up prefetch though J Alternate data streams are good for hiding things. Dir /r will show you the ADS of a file (or folder, or whole directory tree) Echo hello > junk.txt Dir junk.txt Echo hidden text > junk.txt:myADS Type junk.txt Type junk.txt:myADS
Data’s thoughts – 1
First email from Data Based on the intel below, here are some other thoughts: 1. Familiarity with wevtutil (windows command line event viewer) and the GUI event viewer will make their lives easier. Since server 2003, MS has made it a requirement that ‘if you can do it with the GUI, you can do it with the command line’. So there’s always a command line equivalent… somewhere. It isn’t always convenient. 2. Tunnelling might be something worth touching on. Can

Snorter 3 – Binary Digits
Here we simply have this array of binary numbers which somehow have to be decoded. There was a clue about sometimes needing a different perspective. 1111111111111110010011001001100100110010011000001100000100000000001111001111101100001 1000001000000110000001100000011111000111100000001111111111111110010011001001100100110 0100110000011000001000000011111111111111000100100010010001001001100101110011101111100 0110000000001111101111111100000110000011000001100100111110110111010000100000000001111 1111111111000100100010010001001001100101110011101111100011000000001111111111111110010 0110010011001001100100110000011000001000000011111111111111100100110010011001001100100 1100000110000010000000111111111111110000110000110000110000110000111111111111110000000
Hidden Data – Challenge 4
For this challenge we were presented with the following QR code and asked what was wrong with it. Comparing with other QR codes online, it should become quickly apparent that they all have distinctive squares in three corners. In this example, on of the squares is not filled in and as these squares are used by the reading software to align the code and decide which way up it should be this one cannot be read. The first step to
Snorter 2 – It’s letters Jim
I am most grateful to Data for finally providing a solution to this vexing problem. We were supplied with the attached file and simply told “ASCII is not the only way to represent text.” Jim.txt Data writes: Answer: *It’s in EBCDIC!* When decoded using EBCDIC it reads: *CiBt’Bs S0^S0sCeCbCcCdCiCc|* Essentially, what the clue says is that ASCII, while one of the most common character encoding methods, isn’t the only one. I checked the file in a hex editor (always a
