Nyetya ransomware: what you need to know

Nyetya, a variant of the Petya ransomware, is spreading across businesses all over the world. Although it shares the same qualities as WannaCry -- a ransomware deemed ‘one of the worst in history’ -- many cyber security experts are calling it a more virulent strain of malware that could cause greater damage to both small and large organizations.

Nyetya ransomware: what you need to know

Nyetya, a variant of the Petya ransomware, is spreading across businesses all over the world. Although it shares the same qualities as WannaCry -- a ransomware deemed ‘one of the worst in history’ -- many cyber security experts are calling it a more virulent strain of malware that could cause greater damage to both small and large organizations. Here’s everything we know about it so far.

Worse than WannaCry

Nyetya is deemed worse than WannaCry mainly because it spreads laterally, meaning it targets computers within networks and affects even systems that have been patched. Because it also spreads internally, it needs to infect only one device to affect several others within a single network.

Cyber researchers trace its origins to a tax accounting software called MEDoc, which infected 12,500 systems in Ukraine. Since the initial infections in June, it has spread to thousands of networks in 64 countries. And although it hasn’t spread as fast as WannaCry, it might have a wider reach soon because it uses three attack pathways to infect a system. It hasn’t made as much money as WannaCry, which is why cyber researchers are concluding that the attacks are not economically motivated.

Don’t pay the ransom

Cyber security firms and researchers strongly recommend affected businesses to avoid paying the ransom. According to them, paying the ransom would be a waste since the infected user won’t be able to receive a decryption key to unlock their files or systems. This is because the email provider has blocked the email address on the ransomware message.

Although it operates like a ransomware -- locking hard drives and files and demands a $300 ransom in Bitcoin -- it functions more as a wiperware that aims to permanently wipe out data and/or destroy systems. So far, it has affected big-name multinationals in various industries, including Merck, Mondelez International, and AP Moller-Maersk, among others.

Perform backups and update outdated security patches

The only way businesses can be protected is by performing backups and staying on top of patch updates.

It’s safe to say that in case of a Nyetya attack, there’s no chance of getting back your data. In such a scenario, you would have only your backup files -- whether on an external storage or in the cloud -- to fall back on. But backing up is not enough; you should also ensure that your backups are working, which you can do by testing them regularly. Given the nature of Nyetya, you should also make sure that your backups are stored off-site and disconnected from your network.

Like its predecessor, Nyetya exploited vulnerabilities in unpatched Microsoft-run computers. As a business owner, make it a part of your cyber security routine to update your systems with the latest security patches, or risk having your files or systems permanently corrupted.

As a business owner whose operations’ lifeline depends on critical files, your backups are your insurance. If your systems’ network security needs another layer of protection, get in touch with us today.

When did you last update your firmware?

Most IT consultants constantly remind clients of how important it is to update and patch their software, but neglect the importance of updating hardware. We don’t mean replacing it with new hardware; we mean updating the applications and settings coded into the physical IT powering every modern office.

When did you last update your firmware?

Most IT consultants constantly remind clients of how important it is to update and patch their software, but neglect the importance of updating hardware. We don’t mean replacing it with new hardware; we mean updating the applications and settings coded into the physical IT powering every modern office.

What is firmware?

Firmware is a very basic type of software that is embedded into every piece of hardware. It cannot be uninstalled or removed, and is only compatible with the make and model of the hardware it is installed on. Think of it like a translator between your stiff and unchanging hardware and your fluid and evolving software.

For example, Windows can be installed on almost any computer, and it helps users surf the internet and watch YouTube videos. But how does Windows know how to communicate and connect with your hardware router to do all that? Firmware on your router allows you to update and modify settings so other, more high-level, pieces of software can interact with it.

Why is firmware security so important?

Firmware installed on a router is a great example of why addressing this issue is so critical. When you buy a router and plug it in, it should be able to connect devices to your wireless network with almost zero input from you. However, leaving default settings such as the username and password for web browser access will leave you woefully exposed.

And the username and password example is just one of a hundred. More experienced hackers can exploit holes that even experienced users have no way of fixing. The only way to secure these hardware security gaps is with firmware updates from the device’s manufacturer.

How do I protect myself?

Firmware exploits are not rare occurrences. Not too long ago, a cyber security professional discovered that sending a 33-character text message to a router generated an SMS response that included the administrator username and password.

Unfortunately, every manufacturer has different procedures for checking and updating firmware. The best place to start is Googling “[manufacturer name] router firmware update.” For instance, if you have a DLink of Netgear router, typing “192.168.0.1” into a web browser will allow you to access its firmware and update process, assuming you have the username and password.

Remember that routers are just one example of how firmware affects your cyber security posture. Hard drives, motherboards, even mouses and keyboards need to be checked. Routinely checking all your devices for firmware updates should be combined with the same process you use to check for software updates.

It can be a tedious process, and we highly recommend hiring an IT provider to take care of it for you. If you’re curious about what else we can do to help, give us a call today!
