Hey everyone, cozyplanes here with another quick excel prank i thought of.

It is called TEEST, and the technique behind is simple, but interesting. Recommend taking a look, and pranking with your friends.

The following is the README of TEEST (Text in Excel Every Single Time) in Github.
You can check the simple project here ( https://github.com/cozyplanes/teest )

Disclaimer: Do not use or modify neither the program or the source code to make software violating the law.

### How do I use it?

1. Head to https://github.com/cozyplanes/teest and download the latest release `EXE` file.
1. Windows may warn you with the missing signature. The file is a DEBUG file, so there isn't a publisher signature. You can proceed downloading anyway since it has been virus checked by the developer.
2. Type the message you want to display in the textbox.
3. Click `Save text` button.
5. To check the file, click `Cancel` button in the opened popup dialog.

### What happens?

When an MS Excel file (`.xlsx`) has been opened, by using TEEST, two files gets opened.

1. The original file user opened
2. Excel file named `message.txt` with the custom message you have written.

`message.txt` excel file will open every single time a person opens a excel file.

*In some older versions of Excel, the message may overlap with the user opened file.*

### Why does this happen?

When MS Excel program is executed, it is programmed to check the files in the following 2 folders.

- `C:\Program Files\Microsoft Office\Office[versionnumber]\XLSTART`
- `C:\Users\%username%\AppData\Roaming\Microsoft\Excel\XLSTART`

In normal conditions, there is no file in those folders (or the folders doesn't exist at all) but when you use TEEST and click `Save text` button, it saves `message.txt` file in the folders above. From MS Excel is executed again, it will find out there is a file in the folders above, so it will show those text files in Excel.

### Where is this technique used?

There should be a lot of software using this trick, but it is widely known for ransomwares such as `GandCrab` and `TeslaCrypt` displaying decryption methods in MS Excel by this trick.

### How can I disable it?

1. Open TEEST again.
2. Click `Save text` button and click `Cancel` in the following popup.
3. Delete `message.txt` file in the opened explorer.

Back story tldr: our team had certification on using sitecore, because client asked...

So we have completed training, it took 4.5hours. Must say, I expected no less of training from India, though respect points to mentor, surprisingly he had quite understandable accent.

Anyway, was working whole training on my side project, so just had quick glances on the screen what that guy was doing. But he just confirmed my opinion about sitecore - it’s a pile of shit. Then he tried to publish all the changes he made and (drums playing 🎶) after minute of loading - error (attached screen). Oh and he was keep mentioning how beautiful and awesome sitecore is 🤮.

After training last part was left: a questionnaire of 13 questions. To pass, at least 70% score is needed. Questions in docx, and answers supposed to be entered in excel file and then sent via email.

Ok, I open excel file on mac with numbers, I see 3 sheets:
1. Table with empty cells for answers
2. Table with correct answers
3. Scores that should be calculated after submitting.

Well, numbers (app) doesn’t support all excel features, so turns out sheet2 was supposed to be protected with password, and third one be hidden until answers are submitted. What a fail.

So yeah, I completed accreditation with 100% and don’t even remember a shit about sitecore.
