English [Cybercamp 2015] [Forense 2.2] Write Up

Description

The company of Mr. Garcia has been robbed of 74,300€ from his bank account. The theft was committed without the knowledge of Mr. García or people in charge of IT.

Some of the money has been retrieved thanks to the speed of the bank to block the target account, but Mr. Garcia is determined to know how this unfortunate incident occurred, as he invested in forming security technicians and purchasing a perimeter antivirus solution for workstations.

After the incident, we have been asked to do a forensic analysis of the machine, but unfortunately these devices have been handled incorrectly and have no value for our review. Fortunately the system administrator, before the network failure, (do not know if caused by the incident) got a file with network traffic of the same day as the theft of bank accounts.
