Gas Attack Writeup
MISSION BRIEFING
Greetings, Special Agent K. We have an urgent and very grim scenario on our hands. About 20 minutes ago, we received word from one of our red teams, that they’ve uncovered plans on the dark-web to test a new neuro-toxic gas on an undisclosed city.
The group’s name has not yet been uncovered, but is believed to operate decentralized online, sharing the same ideal in the radical right spheres. Over the past months, we’ve observed talks and discussions, glorification of and finally concrete plans to build a dirty bomb.
As of today, our HUMINT team was able to infiltrate partial circles of the group. Our Red Team was able to pull images from the browser cache of the member our HUMINT team was in contact with.
The image reveals a city, which is believed to be the testing ground for the dirty bomb. We still do not have a time-frame for the attack, all we know is that the amount of gas will cost hundreds of people their lives. Not to mention the suffering ending caused by the gas itself.
Our priorities are to find out more about the group, this is done in collaboration with EUROPOL, hence our main task is finding the location of the city. We hope the realization that the location of their plans has leaked, will cause some of the members to make a bad move.
Your task is to locate the city in the image below.
As always, Special Agent K. The contract is yours, if you choose to accept.

METHODOLOGY
The RevEye Reverse Image Search is a tool that can be used for geolocation by comparing the image you are searching for with a database of images and matching it with similar images that have been previously geotagged with location information. This can be a useful tool for OSINT analysts who are attempting to determine the location of an image that does not have any associated geotags or metadata. However, it is important to note that the accuracy of the geolocation information provided by the RevEye Reverse Image Search will depend on the quality and quantity of geotagged images in its database, as well as the similarity of the image being searched for to the images in the database. As such, it is just one of many tools that OSINT analysts can use for geolocation, and should be used in conjunction with other geolocation techniques in order to achieve the most accurate results.
