Various Federal and cybersecurity advocates have released numerous announcements this year, highlighting the increase in ransomware attacks in the United States. Many of the notices indicate that the rise in ransomware attacks is directly related to attacks on enterprises: the large targets are paying substantial amounts of money to regain access to their data. And, as a result, the cybercriminals are expanding their “business”.

While the increase in attacks is likely correct, the troubling issue is the continued increase in successful attacks. The bad guys are winning and gathering financial gain in the process.

On November 18, Louisiana found itself, once again, in a painful situation. Ransomware struck the state networks and resulted in a decision to shutter various agencies in order to reduce the spread of the ransomware. The governor’s office indicated that the Departments of Health, Children and Family Services, Motor Vehicles, Transportation and Governor John Edwards were closed as a result of the attack.

The state’s cybersecurity response team was activated and moved quickly to contain the ransomware. Based on various reports, the team isolated the malware and began an aggressive server restore process.

A statement indicated that no data loss occurred and no ransom was paid.

Several researchers revealed that the attack was similar to one on Louisiana’s public school systems in July. The ransomware was a variant of the popular Ryuk malware.

The real story here is Louisiana’s response: no ransom payment. The team was able to contain the situation, and, due to a careful eye to proper backups, restored operations. The disruption may have been annoying, perhaps inconvenient, but the message was very clear: the disaster recovery plans worked. As a result, the bad guys’ efforts were wasted. Chalk one for the good guys and adhering to good computing hygiene.

As I’ve mentioned before, sometimes the best practice is a solid, tested defense. Louisiana could have poured millions of dollars into the latest shiny object or expensive consultants. Instead, they created a method for containing cyber attacks and built a strong cyber hygiene program, all of which are predicated on two things: updating software and following a rigorous backup routine.

So, speaking of updates, the would-be bad guys are actively impersonating Microsoft.

According to online reports, a spam campaign has been launched, offering a Windows 10 update.

The malware is disguised within the fake Windows 10 update, likely the Cyborg ransomware. When installed, instead of Windows 10, you will have a locked PC and a demand for ransom.

Given that Microsoft releases patches routinely and aggressively pushes the Windows 10 platform, impersonating a Windows 10 update is a clever way to trick users.

But, here’s the thing. Microsoft never announces updates or provides downloads to its software through email links.

What should you do if you receive one of the Microsoft Windows 10 update email messages?

Delete it. Don’t forward it, don’t preview it, don’t open with your mobile device. Just delete it.

Despite the increased attacks to large enterprises, the largest volume of successful ransomware attacks continue to occur with individual users and small businesses.

So, how do you build a solid defense to ransomware?

Start with some basic computer hygiene.

Pay attention to email, avoid opening unsolicited attachments, don’t click on emailed links. Additionally, stop sharing data via fistfuls of thumb drives. There are many efficient and secure methods for sharing files: consider Microsoft’s OneDrive, Google Drive, Dropbox, as examples.

Next, avoid running pirated, or, stolen software.

If you download files via torrent sites or enjoy “borrowing” software from pirated software sites, you’re not only likely breaking many laws, but, you’re exposing yourself to untrusted software, all of which could be loaded with malware. Use licensed software or download open source tools from trusted sites.

And, of course, keep your software updated.

Backup your files frequently and properly. Most modern devices include an online backup service – enable the service for your devices and review that all of your important files are backing up correctly.

Despite all of our efforts to have a good defense and adhere to best practices, there is still a chance that we all can fall victim to a scam and end up with an infected or broken device. Having your files backed up properly is the best way to avoid losing your data or having to run the risk of paying a hefty ransom.

As the holiday season approaches, the scammers will be more vibrant than ever. Below are a few items to help you increase your awareness and hygiene to avoid the most common of email scams.

First, be cautious, even paranoid with links.

Don’t click on email links, especially if you find the content questionable or suspicious. Hover over the link and see if the link’s actual address matches its display name. Also, open a web browser and visit the site directly: type the link into the browser and avoid clicking the link completely.

Second, watch for grammar and typographical issues.

Since the beginning of phishing and scam messages, typos and grammar problems have drawn attention to the legitimacy of the messages. Old, or, dated images often suggest problems as well. Reputable companies don’t send poorly-written inquiries.

Lastly, use multi-factor authentication.

If you fall victim to an impersonation attack and offer your credentials, at least with two-factor, you will have a parachute, of sorts. If two-factor is available use it and pay close attention to the requests you receive for the second form of verification. If you receive one and you didn’t initiate the request, don’t approve it.
Pay attention to the basics and enjoy a safer computing experience.

Be safe.
