I was like, "Wait, what am I doing?" She's giving me access she's giving me access to a locked uh locked room where you normally need to batch. So, um I'm going to tell my story which is uh not in a industrial setting but more in an office setting. Uh my objectives were also gaining physical access of course and then planting a road device and take pictures of sensitive documents or anything like a laptop that they left laying around. For the recon phase, I went there and I saw that it was like a medium to large office. Um, I saw there was a revolving door and I saw people getting in and out the whole time and

the door kept spinning. So, I thought, okay, that looks good. And I saw elevators um inside the building because it was a big glass panes and I saw there was in front of a receptionist desk. So, I will be inside of them. Um, but yeah, I thought tailgating looks possible and I saw people in the streets wearing company merch. So, I thought, you know, during noon, I'm just going to go follow some of them and I'll just tailgate behind them. I um I thought I wouldn't even need a fake batch. Um but when I tried to tailgate, it was actually a smart tour, so it saw that I didn't batch and it turned me back twice while

someone else was also coming from the opposite side and we looked ice and was quite awkward because we turned back very slowly and we crossed eyes and it was like, "No, that doesn't work." I tried that again and then it happened again and I was like okay this is not going to be as easy as I thought. Um so after that I saw that one of the colleagues there was smoking outside. So I talked to him and I said you know I'm a consultant. I was like wait what am I doing? She's giving me access she's giving me access to a locked locked room where you normally need to bat. So I was like okay you know what I actually do

would like to go eat it in the canteen. Uh so she brought me there and of course normally you need to batch to enter it. So I thought so I thought okay jackpot I got in that was easier than I thought in the end. Um but then suddenly they came back with the receptionist lady. Um and she looked quite um concerned like on the picture and they started rapidfiring questions at me with three uh while I was sitting there they were surrounding me and asking questions. Um, so I had to be fast. And she was like, "Who are you? I thought you I thought you were going to wait. Uh, I thought you were going to

wait downstairs. What are you doing here? How did you get in here?" The other guy was like, "Um, who are you? This is a sensitive department. Normally only authorized personnel is allowed." Um, like they could spot me immediately that I did not belong there. Well, I didn't win yet because I made a stupid mistake afterwards.
