Given that the logs show successful logins and the use of strong encryption, it's unlikely that the attack was technical (like packet sniffing, dictionary attack, or brute force) because these methods would not typically result in successful logins without detection. Social engineering, however, involves manipulating individuals into breaking normal security procedures, such as by giving away their login credentials, which would allow for successful logins as seen in the logs.
