Cyber-Ark survey reveals extent of insider threat.

CyberArk Software : 30 May, 2007  (Technical Article)
Snooping IT staff, unchanged power user passwords and insecure storage of access passwords paints poor picture of UK industrial IT security.
Whilst you sit at your desk working innocently away, little do you realise that one in three of your IT work colleagues are snooping through company systems, peeking at confidential information such as your private files, wage data, personal emails, and HR background, just by using the special administrative passwords that give IT workers privileged and anonymous access to virtually any system. One IT Administrator laughed out loud as he answered the survey, saying: "Why does it surprise you that so many of us snoop around your files, wouldn't YOU if you had secret access to anything you can get your hands on!" These are the findings of a survey released today by Cyber-Ark Software, specialists in digital vaulting solutions for securing administrative passwords, who carried out the research at last month's Infosecurity Exhibition as part of their annual survey into "Trust, Security and Passwords".

As if that weren't bad enough, the survey found that more than one-third of IT professionals admit they could still access their company's network once they'd left their current job, with no one to stop them.

More than 200 IT professionals participated in the survey with many revealing that although it wasn't corporate policy to allow IT workers to access systems after termination, still over one-quarter of respondents knew of another IT staff member who still had access to sensitive networks even though they'd left the company long ago.

It seems that very little changes year over year - more than half of people still keep their passwords on a Post-It note, in spite of all the education and reminders to do differently. What's shocking about this year's annual survey was that the 50% number now applies to IT Professionals as well! More than half of respondents admitted to using Post-It notes to store administrative passwords, the super-powerful codes pre-built into every system such the Administrator ID on your local workstation.

As one IT Administrator explained: "Sure, it's easy for an employee to update the personal password to their laptop, but to change the Administrator password on that same machine? It would take days for IT to do them all by hand. In the end, we just pick one password for all the systems and write it down."
And where do they write it? A Post-It note.

One-fifth of all organisations admitted that they rarely changed their administrative passwords with 7% saying they NEVER change administrative passwords. This may explain why one-third of all people questioned would still have access to their network even if they'd left the company. 8% of IT professionals revealed that the manufacturers default admin password on critical systems had never been changed, which remains the most common way for hackers to break into corporate networks.

Gary McKinnon who has been named as the "most profligate military hacker of all time" (and is still waiting to be extradited to the US) for gaining entry to 90 computers at the US Department of Defense by scanning the US military computer systems for blank administrator accounts says: "The easiest way to infiltrate a company's network is to look for administrative passwords which are left blank, still have the manufacturers default password or just use obvious names. Once you find these, which are unbelievably simple and common to find, you're into the system and have the highest level of authority - bingo you've got control of the company's system."

The survey also shows that the majority of companies mismanage the storage of administrative passwords by keeping them in unsecured locations and hence not controlling access to these critical codes. 57% of companies store their administrative passwords manually, 18% store them in an excel spreadsheet (which are notoriously insecure and easy to access), and 82% of IT professionals store them in their heads - hindering security efforts, business continuity, as well as the auditing, controlling and managing of passwords. In the event that the keeper of these critical administrative passwords is unavailable or loses the location of the passwords, it can cause massive disruption and hours of lost productivity.

In other words, don't throw out any Post-It notes laying around the IT department… you may never get into your workstation again!

15% of companies interviewed had experienced insider sabotage, which is not surprising considering that over one-third of IT staff report using administrative passwords to snoop around corporate systems. Even worse, such snooping can turn ugly when IT workers feel disgruntled, aggrieved and especially after they've been fired. According to a recent study by Carnegie Mellon University, the most common insider attack is by a disgruntled IT employee using anonymous access from a privileged account.

Calum Macleod - European Director for Cyber-Ark said: "It's surprising to find out how rife snooping is in the workplace. Gone are the days when you had to break into the filing cabinet in the personnel department to get at vital and highly confidential information. Now all you need to have is the administrative password and you can snoop around most places, and it appears that is EXACTLY what's happening. Companies need to wake up to the fact that if they don't introduce layers of security, tighten up who has access to vital information, and manage and control privileged passwords, then snooping, sabotage and hacking will continue to be rife!"
