SMB routers targeted by VPNFilter malware

Earlier this year, news broke that a malware strain named VPNFilter was infecting hundreds of thousands of devices. If you didn’t act then, now’s the time. Security experts have updated their threat assessment and its much worse than they originally thought. Small businesses are especially at risk and need to take action.

VPNFilter recap

A team of security researchers from Cisco released a report that a strain of malware had been discovered on hundreds of thousands of routers and network devices. Originally, researchers believed it affected only Linksys, MikroTik, Netgear, and TP-Link devices.

Like many malware strains, VPNFilter infects devices that use default login credentials. But it’s worse than the average cyberattack because it can destroy router hardware and cannot be removed by resetting infected devices.

As if destroying 500,000 routers wasn’t bad enough, VPNFilter lets its creators spy on networks and intercept passwords, usernames, and financial information.

What’s new

Just two weeks after VPNFilter was discovered, security experts announced that it targets 200,000 additional routers manufactured by ASUS, D-Link, Huawei, Ubiquiti, UPVEL, and ZTE. Worse yet, VPNFilter can alter data passing through infected routers. That means when you enter a username and password into a banking website, hackers could steal that information and show you an incorrect account balance to hide fraudulent deductions.

How to stop VPNFilter

Rebooting a router won’t remove the malware, you need to factory-reset the device. Usually, all this requires is holding down the Reset button on the back of the device for 10-30 seconds. If your router has no reset button or you’re unsure whether pressing it did the trick, contact a local IT provider immediately.

Cybersecurity threats have become so prevalent that even large enterprises struggle to keep their digital assets safe. Outsourcing IT support to a managed services provider like us will give you enough capacity to deal with issues like VPNFilter as soon as they arise. Call us today to learn more.

Beware of what you save in web browsers

Passwords are a double-edged sword. If you make them too simple, they’ll be easy to guess; if you make them too complex, they’ll be impossible to remember. One solution is to create an uncrackable password and save it to your browser. Unfortunately, recent research suggests that tactic could drastically reduce your privacy.

Why auto-fill passwords are so dangerous

In 2015, the average internet user had 90 online accounts, a number that has undoubtedly grown since then. This has forced users to create dozens of passwords, sometimes because they want to practice healthy security habits and other times because the platforms they’re using have different password requirements.

Web browsers and password manager applications addressed this account overload by allowing usernames and passwords to be automatically entered into a web form, eliminating the need for users to hunt down the right credentials before logging in.

The process of tricking a browser or password manager into giving up this saved information is incredibly simple. All it takes is an invisible form placed on a compromised webpage to collect users’ login information without them knowing.

Using auto-fill to track users

Stealing passwords with this strategy has been a tug-of-war between hackers and security professionals for over a decade. However, it has recently come to light that digital marketers are also using this tactic to track users.

Two groups, AdThink and OnAudience, have been placing these invisible login forms on websites as a way to track which sites users visit. These marketers made no attempts to steal passwords, but security professionals said it wouldn’t have been hard to accomplish. AdThink and OnAudience simply tracked people based on the usernames in hidden auto-fill forms and sold that information to advertisers.

One simple security tip for today

Turn off auto-fill in your web browser. It’s quick, easy, and will go to great lengths to improve your account security.

  • If you use Chrome – Open the Settings window, click Advanced, and select the appropriate settings under Manage Passwords
  • If you use Firefox – Open the Options window, click Privacy, and under the History heading select “Firefox will: Use custom settings for history.” In the new window, disable “Remember search and form history.”
  • If you use Safari – Open the Preferences window, select the Auto-fill tab, and turn off all the features related to usernames and passwords.

This is just one small thing you can do to keep your accounts and the information they contain safe. For managed, 24×7 cybersecurity assistance that goes far beyond protecting your privacy, call us today.

Secure your business with these IT policies

2016Feb9_Security_CEmployees are one of your biggest security holes. There is no foolproof prevention method for human error, and this is why employee mistakes are one of the most common causes of a security breach. So what can you do to prevent it? Well at the very least you need to include policies in your employee handbook, and ensure your employee reads through it and signs off on agreeing to abide by them. Having measures in place drastically reduces the chances of a security breach. Here are four areas to keep in mind when developing your own.

Internet

In today’s business world, employees spend a lot of time on the Internet. To ensure they’re not putting your business at risk, you need a clear set of web policies. Here are three important ones to keep in mind:

  1. Employees should be using the Internet for business purposes only. While this is undoubtedly hard to avoid without blocking specific websites, having a policy in place should at least cut back on employees spending time on non-business related sites.
  2. Prohibit unauthorized downloads. This includes everything from music to games, and even data or applications.
  3. Accessing personal email should not be done on business devices. If employees must access their own email account during the day, they can do so on their smartphone or other personal device.

These are just a few Internet policies to get started, but you should also consider including information on your recommended browsing practices and your policies for using business devices (such as company phones) on public wifi.

Email

Just like with the Internet policy mentioned above, company email accounts should only be utilized for business use. That means your employees should never use it to send personal files, forward links or perform any type of business-related activities outside of their specific job role. Additionally, consider implementing a standard email signature for all employees. This not only creates brand cohesion on all outgoing emails, but also makes it easy to identify messages from other employees, and hence helps prevents spear phishing.

Passwords

We’ve all heard the importance of a strong password time and time again. And this same principle should also apply to your employees. The reason is rather simple. Many employees will create the easiest to crack passwords for their business accounts. After all, if your organization gets hacked, it’s not their money or business at stake. So to encourage employees to create strong passwords, your policy should instruct them to include special characters, uppercase and lowercase letters, and numbers in their passwords.

Data

Whether or not you allow your employees to conduct work on their own device, such as a smartphone or tablet, it is important to have a bring your own device (BYOD) policy. If your employees aren’t aware of your stance on BYOD, some are sure to assume they can conduct work related tasks on their personal laptop or tablet. So have a BYOD policy and put it in the employee handbook. In addition to this, make sure to explain that data on any workstation is business property. That means employees aren’t allowed to remove or copy it without your authorization.

We hope these four policies have shed some light on best security practices. If you’d like more tips or are interested in a security audit of your business, do get in touch.
