Have you heard about ransomware? It’s a
growing threat to individuals and businesses across the world, and your
business could be next.
How serious is the threat? On June 27, a
ransomware attack affected hundreds of thousands of users in Ukraine and
Russia, targeting some of those two countries’ biggest businesses and
organizations, including Rosneft and the organization that manages the
Chernobyl nuclear accident site.
The attack, called the WannaCry virus,
exploited a previously unknown security backdoor to spread between
Windows-based PCs. WannaCry was originally developed by NSA and was leaked into
the dark web. There, it was obtained by cybercriminals who used it to deny
access to software and systems used by more than 200,000 PCs around the world.
Victims of the attack, including FedEx, Renault, Nissan and a number of
American universities, were denied access to their applications and systems unless a ransom was paid in BitCoin (a type of untraceable virtual
currency) to the hackers behind the virus.
So, what is ransomware, and how can you
protect your business?
What is Ransomware?
Ransomware is malicious software that can
deny you access to your computer by locking your keyboard, computer,applications
or files unless you pay a ransom to unlock them. The ransom is usually demanded
to be paid using Bitcoin, a type of digital currency that makes it nearly
impossible to trace where the payment is going. This makes it very difficult to
catch these cyberattackers.
These types of attacks are not new, but
they’ve become more sophisticated in recent years. In no small part this is due
to the fact that they’re being developed by governments (including the United
States) as cyberweapons.
These types of cyberweapons were intended
to be used against other governments rather than private individuals or
businesses. But the WannaCry attack demonstrates the widespread damage that
these kinds of applications can do when they are released into the wrong hands.
It also underscores a conflict between governments and others who seek to
exploit weaknesses that might allow technology to be used as a weapon, and
software makers whose job it is to patch those vulnerabilities.
How Can I Protect my Business from Ransomware?
To understand how
to protect your business from ransomware, it’s helpful to understand how it
spreads. Usually, it spreads like other types of malware, through opening an
infected attachment from email or downloading an infected file from a
compromised website. Once this file has been opened, it can begin downloading
files that will block you from using your computer or accessing files.
Because it spreads in this way, one of the
first lines of defense against ransomware should be training users to avoid
clickbait and avoid opening files from people they don’t know. But, hackers are
devious and have developed sophisticated methods to work around these defenses.
Another important defense against
ransomware is monitoring your network to detect malware, and using applicationsthat
prevent opening infected files. Frequent updates to your network security is
also crucial to ensure that your network and devices are protected against
ransomware attacks.
The third and equally critical defense
against ransomware is to ensure that your systems receive regular backups. If a
ransomware attack does hit your business, good backup protocols will ensure
that you do not have to pay the ransom. You can simply reinstall the most
recent uninfected backup of your system files. To prevent data loss, these
backups must be done at least daily or weekly; depending on the amount of data
your business processes, even more frequent backups may be necessary.
Ransomware is a growing threat. A managed
services provider like Tolar Systems can
provide the training, monitoring, prevention, and backups you need to protect
your business against ransomware.
