US officials increasingly are targeted by so-called spear phishing attacks, reason for the US Department of Defense to issue a brochure with advice. The brochure follows two major break-ins at the Office of Personnel Management (OPM) earlier this year.
In addition, the data of millions of civil servants were stolen. The brochure explains how phishing attacks exactly and how phishing mails can be recognized. During an exercise of the army with a phishing test was a phishing email with a malicious Excel file sent to seven users. Two user opened the file, making the 'attackers' ultimate domain administrator on more than 6800 user and computer accounts were 5400. Officials are therefore given in the leaflet to stop the advice to first and think before they click on something.
