Ransomware Attacks: They Could Happen to You

Issue: Volume 3, 2017

Ransomware is a dangerous cyber threat, with attacks on the rise: “From January to September of 2016, total ransomware attacks against businesses increased by 300 percent when compared to 2015.”1 Small-to-midsize businesses (SMBs), which include many dental practices, are often a prime target. Over 50 percent of SMBs have fallen victim to ransomware2, and on average, they spend almost $880,000 to fix damages and recover data.3 When you consider possible fines, lost revenue, and recovery costs, you can see how one wrong click could potentially shut a practice down completely.

What Is Ransomware?
Ransomware is malware that can encrypt your data—patient records, financial and accounting information, payroll and inventory—so they can’t be accessed. The attacker then demands payment for you to regain access to your valuable data.

This is easy money for hackers. If just one of your employees clicks on the wrong link on a website or in an email, your practice is the next victim.

I highly recommend you “insure” your data by using a backup that can restore your files to the point before the system was infected.

Unfortunately, outside experts may be limited in what they can do to resolve these issues. It depends on the severity and circumstances, and what preventative measures were put in place by the office prior to the attack. I recently helped a dental office that had been hit with ransomware. An employee working remotely had been browsing the web and checking email while connected to the office’s server, and it became infected. Because the backup drive was plugged into the server at the office, it got encrypted too. Although they had another backup drive, it hadn’t been used for a while, so the office lost three months of data.

Mitigating the Damage
You need more protection than antivirus software alone. In 2014, researchers tracked 500+ antivirus software evasion techniques in what was then the latest advanced malware.4 I highly recommend you “insure” your data by using a backup that can restore your files to the point before the system was infected. In the last 90 days, 75 percent of TechCentral clients who were dealing with ransomware required a restore from a backup.
