## Details

>An anonymous tipster sent us this photo alleging that it's a note written by b3li3f1203. The tipster claims that the note was intended for someone who works at De Monne Financial. They also said it's likely that it has something to do with a phishing campaign. Provide the name of the target individual as the flag in this format: flag{FirstName_LastName}.

Looking at the image we can see it contains some sort of hand written cipher.


If we enter the string into [CyberChef](https://gchq.github.io/CyberChef/#recipe=ROT13(true,true,false,-14)&input=SHZzIGJzbGggYXNzaHdidSBrd3p6IHBzIGhjcm9tIG9oIGJjY2IuIEJzc3IgaGMgdHdiciBjaWgKWHdhYXdzJ2cga2NmeSBncXZzcml6cyBnYyBrcyB5YmNrIGt2c2Igd2cgcHNnaCBoYyBkdndndgp2d2EuIEh2cyBxb2Fkb3d1YiBic3NyZyBoYyB6Y2N5IHp3eXMgd2ggcW9hcyB0ZmNhCnZ3ZyBwY2dnLCBBb2ZxaWcgUG1ic2YuIFZzIGtjZnlnIG9nIG9iIE9yam9icXNyCkdjemlod2NiZyBHaWRzZmp3Z2NmIC1yY2InaCB0Y2Z1c2hoYyB3YnF6aXJzCmh2b2ggd2IgaHZzIHNhb3d6Lg) and apply a **Rot 13 recipe**, then change the value until we get something readable - in this case -13 (or 38), we get the following;

The challange details said the flag format is the name of the Supervisor. Therefore the flag is;

## flag{Marcus_Byner}
