How companies can escape ransomware clutches

Published

on

As the world feels the after effects of the WannaCry Ransomware virus, South African businesses are asking what they can do to prevent the next attack. BRENDAN MC ARAVEY, Country Manager at Citrix South Africa sheds some light.

Recent news of possibly the largest ransomware attack in history — WannaCry — has permeated the globe. WannaCry is an operating system exploit, one of many that were exposed by Wikileaks. While the original exploit has been patched, that doesn’t mean attackers aren’t trying again.

The traditional approach to mitigating ransomware attacks — user education, anti-malware, frequent backups, and keeping a supply of Bitcoin on hand — is no longer a viable option by itself. Organisations need to turn to a more robust, systems-level approach to keep data out of an attacker’s reach. It’s critical that organisations step up their game — today. And it is more important than ever that we all prepare for multiple versions of attack as well as net new attacks.

The WannaCry attack has already resurfaced and its target list is expanding. Immediately patch the vulnerability, if you haven’t already and follow these steps to ensure you organisation isn’t the next victim.

Patch and virtualize: Paying the ransom does not mean your files will be restored. Aside from the cost, payment only rewards criminal activity, and strengthens the incentive for more attacks across industries. If the bad actor does provide to keys to decrypt, restoration is often a manual process and can take weeks to recover, depending on the number of files impacted.

Run a system check to ensure all patches have been made and that employees are using the most up-to-date softwareWe strongly encourage companies to migrate to Windows 10 and virtualize applications and browsers through Citrix XenApp & XenDesktop, and AppDNA to keep sensitive data off the endpoint. By using Citrix XenApp to run a hosted browser, IT can introduce a layer between the corporate environment and the Internet to shield the trusted computer and its data from attack.

Educate your employees about this attack and their role in protecting the company and themselves. First and foremost, let employees know they shouldn’t open a file or click on a link under any circumstances unless they know whom it’s from. If they are concerned or need to confirm, tell them to pick up the phone or ask a manager.

Mobile devices are prime targets for ransomware and other malware. Containerization is key to preventing attacks on mobile devices by centralizing management, security and control for apps and data without interfering with personal content on a bring your own device (BYOD). Containerization also contains an attack to a single user.

Backup everything with a secure enterprise file sync-and-share service like Citrix ShareFile. Even if the ransom is paid, there’s no guarantee the files will be restored. The options are to restore data from a recent back up or live without the files. ShareFile keeps multiple versions of each file so that in the event a file is encrypted by ransomware, users can revert to the most recent, uncompromised version, eliminating the need for a hacker’s decryption key.

It is therefore clear that virtualization, enterprise mobility management and enterprise file synchronization help shield devices and organisations — computers, tablets, smartphones and other endpoints — against ransomware attacks and allow for quick recovery if an incident does occur. Many of the operating system hacks published by Wikileaks can be mitigated with these types of technologies.

How we use phones to avoid human contact

A recent study by Kaspersky Lab has found that 75% of people pick up their connected device to avoid conversing with another human being.

Published

Connected devices are becoming essential to keeping people in contact with each other, but for many they are also a much-needed comfort blanket in a variety of social situations when they do not want to interact with others. A recent survey from Kaspersky Lab has confirmed this trend in behaviour after three-quarters of people (75%) admitted they use a device to pretend to be busy when they don’t want to talk to someone else, showing the importance of keeping connected devices protected under all circumstances. 

Imagine you’ve arrived at a bar and you’re waiting for your date. The bar is busy, and people are chatting all around you. What do you do now? Strike up a conversation with someone you don’t know? Grab your phone from your pocket or handbag until your date arrives to keep yourself busy? Why talk to humans or even make eye-contact with someone else when you can stare at your connected device instead?

The truth is, our use of devices is making it much easier to avoid small talk or even be polite to those around us, and new Kaspersky Lab research has found that 72% of people use one when they do not know what to do in a social situation. They are also the ‘go-to’ distraction for people even when they aren’t trying to look busy or avoid someone’s eye. 46% of people admit to using a device just to kill time every day and 44% use it as a daily distraction.

In addition to just being a distraction, devices are also a lifeline to those who would rather not talk directly to another person in day-to-day situations, to complete essential tasks. In fact, nearly a third (31%) of people would prefer to carry out tasks such as ordering a taxi or finding directions to where they need to go via a website and an app, because they find it an easier experience than speaking with another person.

Whether they are helping us avoid direct contact or filling a void in our daily lives, our constant reliance on devices has become a cause for panic when they become unusable. A third (34%) of people worry that they will not be able to entertain themselves if they cannot access a connected device. 12% are even concerned that they won’t be able to pretend to be busy if their device is out of action.

Dmitry Aleshin, VP for Product Marketing, Kaspersky Lab said, “The reliance on connected devices is impacting us in more ways than we could have ever expected. There is no doubt that being connected gives us the freedom to make modern life easier, but devices are also vital to help people get through different and difficult social situations. No matter what your ‘connection crutch’ is, it is essential to make sure your device is online and available when you need it most.”

To ensure your device lifeline is always there and in top health – no matter what the reason or situation – Kaspersky Security Cloud keeps your connection safe and secure:

·         I want to use my device while waiting for a friend – is it secure to access the bar’s Wi-Fi?

With Kaspersky Security Cloud, devices are protected against network threats, even if the user needs to use insecure public Wi-Fi hotspots. This is done through transferring data via an encrypted channel to ensure personal data safety, so users’ devices are protected on any connection.

·         Oh no! I’m bored but my phone’s battery is getting low – what am I going to do?

Users can track their battery level thanks to a countdown of how many minutes are left until their device shuts down in the Kaspersky Security Cloud interface. There is also a wide-range of portable power supplies available to keep device batteries charged while on-the-go.

·         I’ve lost my phone! How will I keep myself entertained now?

Should the unthinkable happen and you lose or have your phone stolen, Kaspersky Security Cloud can track and protect your device from data breaches, for complete peace of mind. Remote lock and locate features ensure your device remains secure until you are reunited.
