A recent report by Praetorian, a cybersecurity company headquartered in Austin, TX, focused on threats that resulted in data compromise or access to sensitive information. Based on a review of 100 separate internal penetration test engagements the study identified the five most prevalent threats to corporate data. The amazing thing about these weaknesses is that the top four are all based on utilizing stolen credentials and the last one helps an attacker be more effective in using those stolen credentials. In other words, the enemy is right there in the mirror! The study spanned 75 unique organizations and only focused on security weaknesses that were used to obtain a full network compromise.
