Qlocker security threat targets random businesses

Ransomware attacks are nothing new, but they have been growing rapidly in recent years. One estimate puts that annual cost of such security breaches at $11trillion, with an attack every 11seconds of every day. Now there is a new player on the scene in the form of the Qlocker security threat, and it is something every SME needs to be aware of.

What is the Qlocker security threat?

The Qlocker security threat exploits a weakness in QNAP network attached storage (NAS) systems, which are permanently linked to the net. This is a popular system used by many SMEs to facilitate backups in case of system failure or ransomware attacks, yet this defenc is being used against the system.

The attack does not use malware as such, but exploits the software to password protect the 7zip files used for backup. To get the password to unlock the files, the victim must pay a ransom. This is pitched at an affordable 0.01bitcoin, around £263, to encourage companies to pay. By hitting a huge number of companies, this relatively small amount soon adds up for the attackers.

Why is my company at risk from the Qlocker security threat?

Unlike many ransomware attach, which target specific organisations, such as the NHS or major companies, demanding a large sum, the Qlocker security threat is much more widespread. Their software scans the net for QNAP devices and automatically exploits the weakness. They neither know, or care, who you are or what you do, which means that every company, large or small is vulnerable if they use QNAP NAS.

Unfortunately, your system will not be protected by most antivirus or malware products. The Qlocker security threat simply exploits existing vulnerabilities in the system to execute the password protection scam on your files.

What should I do if I am attacked?

If you experience the Qlocker security threat, you should keep your system running. It is tempting to shut down and reboot, but this will only make things worse. QNAP’s advice is:

* immediately disable myQNAPcloud

* change the default web admin port from port 8080 to another port

* terminate any active ‘7z’ processes

Alternatively, you can contact AGT Computers and we will walk you through your immediate steps and work with you to get you up and running as soon as possible.
