From the previous challenge, we know the password for the Van chase zip file for this challenge round is `Dreamland`.
As such, we can extract the level's challenge folder now:
```bash
7z x VanChase.7z
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,32 CPUs AMD Ryzen 9 3950X 16-Core Processor (870F10),ASM,AES-NI)
Scanning the drive for archives:
1 file, 159864 bytes (157 KiB)
Extracting archive: VanChase.7z
Enter password (will not be echoed): <enter "Dreamland">
--
Path = VanChase.7z
Type = 7z
Physical Size = 159864
Headers Size = 264
Method = LZMA2:192k 7zAES
Solid = +
Blocks = 1
Everything is Ok
Files: 3
Size: 159581
Compressed: 159864
```
Which gives us:
```bash
rw-rw-r-- 1 ganondorf ganondorf 1 KiB Wed Feb 24 13:26:42 2021 Kicks.ps1
rw-rw-r-- 1 ganondorf ganondorf 137 B Wed Feb 24 12:42:31 2021 Kidnap.txt
rw-rw-r-- 1 ganondorf ganondorf 154 KiB Wed Feb 24 13:36:06 2021 TheHotel.7z
rw-rw-r-- 1 ganondorf ganondorf 156 KiB Fri Apr 9 18:06:28 2021 VanChase.7z
```
Displaying the text file:
```bash
cat Kidnap.txt
An idea is like a virus, resilient, highly contagious.
52 49 54 53 45 43 7b 57 61 74 65 72 55 6e 64 65 72 54 68 65 42 72 69 64 67 65 7d
```
So, just convert the hex numbers to their ASCII equivalent; can do so [using CyberChef, for example](https://gchq.github.io/CyberChef/#recipe=From_Hex('Auto')&input=NTIgNDkgNTQgNTMgNDUgNDMgN2IgNTcgNjEgNzQgNjUgNzIgNTUgNmUgNjQgNjUgNzIgNTQgNjggNjUgNDIgNzIgNjkgNjQgNjcgNjUgN2Q).
Flag is `RITSEC{WaterUnderTheBridge}`.
