## WAV1. When the audio file is shown in [Audacity's Spectrogram](https://manual.audacityteam.org/man/audacity_waveform.html#multi), the following text (`thguovdne hsals drawrof yl tod tib`) can be seen:	![Audacity's Spectrogram showing text of a message](https://applegamer22.github.io/posts/nitectf/boys/audio_text_huabd686caddb28ea42071ab6de3ccd504_240667_1320x0_resize_q75_box.jpg)1. By reversing the message, the shortened URL (<https://bit.ly/endvought>) can be read:
	```sh	$ echo "thguovdne hsals drawrof yl tod tib" | rev	bit dot ly forward slash endvought	```
## PNG1. The previously-mentioned shortened URL leads to an image file download:	![](https://applegamer22.github.io/posts/nitectf/boys/7_tower_hu3e170f22d1730067613e3521715007c3_725085_1320x0_resize_box_3.png)1. The shredded red text looks like an email address, but since the email address looks like the one found in the [commit](#github) metadata, I didn't un-shred the picture. **During the event, I had not idea how to continue from here, with the email address in hand.**
## E-mail Address1. **I didn't figure it out during the event**, but once I had Hughie's email address I could find his public Google calendar with the hyper link [calendar.google.com/calendar/u/0/embed?src=`[email protected]`](https://calendar.google.com/calendar/u/0/[email protected]).	* Additional intelligence could be gathered about the email address using tools such as [EPIEOS](https://epieos.com).	* The Google ID of the email address could be gathered by initiating a Google Hangouts chat and inspecting the HTML at the recipient's details.1. The only event during December 2022 has the flag `niteCTF{v0ught_n33ds_t0_g0_d0wn}`.
