Ransomware a Risk for You, Too

by

Ransomware headlines focus on interrupted hospital services or downtime at several major brands. But ransomware can just as easily infect your home computer.

When you’re a victim of ransomware, you aren’t able to do anything on your computer. Cybercriminals encrypt your files and demand you pay a ransom to unlock your device. They’ll ask for cryptocurrency in return for the encryption key.

You may think the bad guys wouldn’t care about your residential system, but you’d be wrong, especially now. Think of all the people at home connecting remotely to business networks. Plus, kids make a weak link as they don’t fully understand the risk.

Many residential antivirus solutions aren’t up to protecting your computer from ransomware.

How to prevent home ransomware

Ransomware in residential homes may not grab headlines, but it’s still going to be big news at your house. Any computers connected to that network with the ability to save to one another could be infected.

The biggest issue with malware of any kind? Your devices may be infected and you might not even know it. Get a cybersecurity solution for your home that looks where you can’t. A good antivirus software that supports anti-ransomware uses machine learning. Artificial intelligence (AI) reviews a database of known threats before running new files on your computer. This helps detect and block any malware before it executes.

Some antivirus software whitelists certain computer folders such as “My Documents,” making it possible for only trusted applications to write to that folder.

You’ll also want to have a good backup. If you’re working on a novel in your spare time, keeping the family photos on your desktop, or developing an in-depth family genealogy, for instance, don’t risk losing access to any of these. Instead, make frequent backups and keep them separate from your network. This can help preserve your personal data in the event of a malware attack.

Always be on the lookout

Phishing is the top way ransomware infiltrates computers. So, talk to all home network users about the need for vigilance. Cyber bad guys are doing a much better job these days of mimicking reputable companies. A phishing email will look like it is coming from a trusted website. They will have worked hard to gain your confidence to open the message and click on their link.

Caution everyone, especially kids, against clicking on links or downloading attachments, especially if the email is making an urgent or emotional appeal.

You can also stay safe by taking care of what websites you visit. It’s hard enough to determine if an email is legit, but now you need to be wary of where you go online? Yes, it’s true. One type of ransomware gets you to download and install the software, while another installs it without you knowing when you visit an infected site.

Steer clear of top culprits such as gambling, pornography, and pirated video sites. When online, look for the lock icon before the domain name: that indicates encrypted Web traffic. And avoid clicking on any download links on the sites you visit.

What to Do If You’re a Ransomware Victim

by

You’ll know if you’re a victim of ransomware. Often you’re met with a red screen telling you your business files are encrypted. You won’t be able to do anything on the computer, although the cybercriminals will provide helpful instructions for how to pay up. How nice. Here’s what to do instead if you’re the victim of a ransomware attack.

Cybersecurity Ventures predicts ransomware will impact businesses every 11 seconds in 2021. Yes, you read that right. That’s up from every 14 seconds in 2019. Another research company reported ransomware increasing 485% year-over-year in 2020.

Know that it’s widely considered a bad idea to pay the ransom because you’re rewarding the cybercriminal. Plus, you can’t even be sure that they will provide the encryption key needed to regain the use of your files. What! You were going to trust the bad guys?

The Important First Step

The first thing you’ll want to do is make it all go away. Yet wishful thinking is not going to get the job done. Instead, you’re going to have to turn immediately to your disaster response plan, because, of course, you have one of those already. Really, don’t underestimate the value of planning in advance for IT infrastructure compromise. Doing it proactively means calm, considered decisions rather than reacting in a crisis.

Step one is going to be identifying the systems involved and isolating them. Once you detect a compromise, limit the spread of infection by disconnecting the devices affected. Ideally, you take only a few computers offline or disconnect an individual network. Even in a large-scale compromise, remove all affected devices from the network to contain the malware.

As part of the isolation, don’t forget to disconnect any connected devices such as storage drives. The ransomware infection will even seek out USB thumb drives.

Power down only the affected devices if you are unable to disconnect them from the network. Why? Because turning them off means you might lose potential evidence.

Malicious actors may be monitoring your business communications. So, move offline to coordinate your response. Phone calls or text messaging will work, or personal email accounts.

Don’t attempt to restore critical systems until you have identified and isolated them. After that, your business can move into triage mode. Prioritize what to restore, and recover using your data backup (again, of course, you have one of those, too). Consider how critical each system is for health and safety and revenue generation. Then, get to work restoring systems in an efficient, organized fashion.

Minimizing Ransomware Risk

Ransomware is a major threat to every business sector, and you don’t want to become the next victim. Common best practices include:

  • preventing an attack with anti-virus and anti-malware tools;
  • installing email filters to keep phishing emails from reaching your employees;
  • making frequent backups and keeping them separate from your network;
  • keeping up with ransomware and other cybersecurity threats.

Businesses that partner with a managed services provider have someone supporting their efforts to cut ransomware risk. Plus, if the worst happens, the MSP’s IT experts are ready to identify and isolate. They can find the samples needed, determine the malware strain you are dealing with, and report the attack.

Your data backup should have recent copies of all information up to (or close to) the time of infection. So, once the MSP has removed all ransomware, they will wipe your systems and storage devices. They can swiftly reformat the hard disks and reinstall everything from scratch.

An MSP can help you plan ahead to contain the damage from a cyberattack. Let our IT experts install best practices, set up safe backups, and track the activity on your network. Contact us today at (515)422-1995.

Lessons Learned from an Oil Pipeline Ransomware Attack

by

Your business may not be supplying oil to the United States, and you may not even be in the critical infrastructure business, but don’t think that means ransomware can’t happen to you, too. This article shares lessons learned from a headline-grabbing event, and they’re applicable to businesses of all sizes in all industries.

First, what happened? The May 2021 ransomware attack crippled a 5500-mile gasoline pipeline. The Colonial Pipeline serves up nearly half of the gasoline used by the East Coast of the United States. The attack thought to be the largest ever on US oil infrastructure, encrypted almost 100 gigabytes of data. Russian hacker group DarkSide took the systems hostage, demanding an undisclosed ransom. The pipeline was offline for days, and the disruption plagued the country for weeks.

The lesson learned? Businesses cannot underestimate the importance of being proactive about preventing cybercriminal attacks. The Colonial Pipeline attack originated in Russia and attacked the US, but the motive was financial. The majority of cyberattacks come down to money. That means your business could be at risk, too.

Lesson #1: Educate employees

Avoid falling victim to a devastating ransomware attack by educating employees about cybersecurity. Train your employees to recognize phishing emails and other scams, teach them about the importance of strong passwords, help them understand the potential dangers of using unsecured wireless networks or unencrypted devices, and prevent their downloading unsanctioned apps onto work computers.

Lesson #2: Use firewalls and email filtering

Configure firewalls to protect your network and block access from malicious IP addresses. Geo-fencing can reduce traffic from foreign actors in known cybercrime hubs.

Additionally, set up advanced spam filters. These help identify and stop phishing emails before they even get to your employees.

Lesson #3: Limit access

You’re thinking you’re doing that already with firewalls and filtering, but this refers to limiting access for the people who work for you. Configure credentials so that employees can access only what’s needed to do their job. Limiting administrative access makes it more difficult for bad actors to do damage.

Also, limit permissions to reduce access. One employee may need to read certain files but have no need to edit them. Configure the file and directory access accordingly.

Lesson #4: Monitor and patch

Even if you’re not online at all hours of the day, you should be monitoring IT 24/7. Set up alerts to identify any suspicious activity. You want to know as soon as possible if there is a vulnerability so your business can limit its exposure.

Also, patch: don’t ignore update notifications from your software providers or operating system manufacturers. Every piece of technology in your office could be an entry point for a bad actor. Cybercriminals are always finding new modes of attack and vulnerabilities. You have to be vigilant and keep your systems updated to cut your risk.

Lesson #5: Have a backup plan

If cybercriminals take your system hostage, you don’t want to have to pay a ransom. It’s costly, and you can’t guarantee you’ll get a functional system back. You will still suffer downtime and a damaged reputation from the attack.

Having several system backups, tested regularly for accuracy, helps protect you from catastrophe. We recommend a 3-2-1 approach. That’s three separate copies of the backup on two different storage types, and at least one of them should be off-site.

Customize your backup plan around the specific needs of your business. One company might be fine backing up daily, whereas another may suffer if it loses even a few hours of data.

Cybersecurity doesn’t have to be complicated

Ransomware attacks are expensive and time-consuming. Partner with a managed service provider to keep an eye on your systems. Our IT experts can configure protection, track activity, and provide backup solutions. Take preventative action to protect your business against ransomware and other cyberattacks.

7 Things You Need to Know About Ransomware

by

Ransomware is a well-named type of cyberattack. Cybercriminals taking this approach kidnap your data. After accessing your network, they encrypt files and demand payment for the passcode. Here are the top seven things you need to know about this business threat.

#1 It Can Happen to You

Cybercriminals rely on your false confidence. Don’t think “it won’t happen to me.” Attacks on government, education, healthcare, or financial institutions get publicity. Yet organizations of all types and sizes are targeted.

#2 Ransomware Spreads Fast

Ransomware is malware, malicious software that can reach throughout a network. So, if Jane from accounting opens a ransomware file, every single computer on your business network could be infected. The virus can spread between businesses, too. Consider the debilitating WannaCry ransomware attack of 2017. Within four days of its first detection in Europe, the strain had spread to 116 countries.

#3 Ransomware Targets People

A common method to send out phishing emails in the hope of having people enter their access credentials. Targeted business communication emails work, too. The attacker gets to know your business first. Then they send an email impersonating a colleague, supplier, or customer asking you to take action or update contact details by clicking on the link or downloading a file.

#4 Ransomware is Costly

Once the ransomware is installed on your system, it locks down your files. To regain access to the files, you need the password or decryption key the attacker supplies when you pay up; that’s if they keep their end of the bargain once you pay the ransom. These are crooks you’re dealing with after all!

In Coveware’s analysis of Q3 2019, the average ransom payment increased by 13% to $41,198 as compared to $36,295 in Q2 of 2019. And that’s just the cost of the ransom. Indirect costs include the cost of downtime, lost revenue, and long-term brand damage. There’s also the expense of removing the ransomware, forensic analysis, and rebuilding systems.

The average ransomware attack in Q3 2019 resulted in 12.1 days of downtime. – Coveware

#5 Ransom Requires Cryptocurrency

Ransom payment is usually made by bitcoin or another cryptocurrency. Your business needs to buy cryptocurrency with actual cash, then transmit the ransom. They choose cryptocurrency because it’s very difficult to trace. It doesn’t help you that bitcoin is not something you can charge back like a credit card.

#6 A Recovery Plan Helps

Planning in advance can help you respond more reasonably. Document plans to disconnect infected computers from the network as soon as possible. Also, power down any machines that could be vulnerable to avoid spreading contagion.

You should also discuss in advance whether or not your business will pay a ransom. Weighing the costs and benefits without a deadline on the decision can help you react more strategically.

#7 You Can Take Action

You don’t have to sit around worrying and waiting for a ransomware attack. There are many things you can do to help prevent this type of attack:

  • Filter traffic, preventing it from coming into your network in the first place.
  • Scan inbound emails for known threats, and block certain attachment types.
  • Use antivirus and anti-spam solutions and regularly upgrade and patch vulnerable software.
  • Educate all users about social engineering.
  • Allow remote access to your network only from secure virtual private networks.
  • Back up your data to more than one location so that you can restore any impacted files from a known source.

Ransomware is a lucrative, relatively easy mode of attack for cybercriminals. They could target your business. Contact us today for help implementing the best protection practices to keep your data safe. Call us at (515)422-1995.

Should You Pay for a Ransomware Attack?

by

Getting hit with a ransomware attack is never fun, your files get encrypted by cybercriminals and you’re left having to decide: should we pay to get them back? It’s a scene that’s played out across the world with 70% of businesses saying ‘yes’ in 2016 alone.

Personally, I don’t recommend paying a ransom. It encourages the criminals to keep doing what they are doing. However, as a small business owner, I could definitely see the desire to pay the ransom, get my files back, and make this all go away. I am adamant with all of my clients to have a good offsite backup just as we do. Not all have chosen to go that direction, but hopefully, you do, as it is just a matter of time before it is needed. Now, should you pay the baddies? Here’s what to consider.

Do you trust them?

Besides the fact that they’re criminals holding your data hostage, how confident are you that they’ll send the decryption key? Most attackers demand you send the payment via untraceable cryptocurrency, so you have no recourse if they take it and run. You’re also equally trapped if they decide they asked too little and come back with increasingly higher demands. If they do send the decryption key, be aware they still have access to your systems and can hit you again at any time until your network is disinfected by experts. Businesses don’t exactly want their breach publicized either, so many don’t admit to paying the ransom, whether it went to plan or otherwise.

Can you manage the impact?

Best case scenario, you can wipe the affected drives and restore from a clean backup without paying the ransom. You might even decide the encrypted files aren’t that important and simply let them go, or even wipe a whole laptop or workstation. On the other hand, if your data management comes under any special regulations, like health or legal, you may find the attack has a much wider, more intense impact. The attacker will usually give you a countdown to motivate a payment, with a threat of deletion when it hits zero. If the data isn’t that valuable, or you have confirmed backups, this urgency has no effect.

How much do they want?

Cybercriminals rarely send out global attacks with set amounts, instead, they prefer to customize the ransom based on how much they think you can pay. Large corporations and hospitals are hit with very high demands, while small business demands are more modest. They may be criminals, but they’re smart people who know your financial limits. They’ll also consider how much similar businesses have paid and how quickly, then expect you to follow suit.

Are your backups good?

Many businesses are discovering too late that their backup systems aren’t robust enough to withstand this type of attack. Either they’ve become infected too, they weren’t up-to-date, or they backed up the wrong data. It’s worth doing some quick checks on your backup processes as even if you have to take the system down for a day as you recover, you’re still light years ahead of those without them.

What’s your policy?

More and more often, businesses are adding ransomware to their disaster recovery plans and having predefined actions mapped out. Seemingly simple inclusions like who has final say over the payment decision can stop chaos in its tracks. Employees and management alike can then approach the situation calmly, ready to make the best decisions for the business.

Stay safe in the first place

Ransomware is showing no signs of slowing down. As more businesses keep them funded the cybercriminals are steadily launching new attacks and making it their full-time job. Most attacks come via phishing emails – those emails that trick employees into clicking a link – and they can be extremely convincing. While training helps people spot them, it’s no guarantee. We recommend using business-class spam filters to catch these types of emails before they land in your employee inboxes so that triggering a ransomware attack becomes something that happens to other businesses, not yours.

How Much Could A Ransomware Attack Cost You?

by

How Much Could A Ransomware Attack Cost You?

Have you ever thought about how much your data is worth? Information is possibly the most valuable part of your business – there’s your client database, accounting software and inventory management, and of course, any intellectual property you may own.  When the ransomware, WannaCry, tore through the world recently, many businesses were suddenly forced to re-assess the value of their data: was it worth saving, and what would be the deeper cost of the attack?

Most ransomware attacks cost $150-$600 to get your files released, but that’s only IF the cyber-criminals honor the payment and actually give you the decryption key. Meanwhile, new client calls are still coming in and you may find yourself unable to operate with your systems down. Paying the ransom or restoring from an unaffected backup seems like a quick fix, but it doesn’t end there. There’s still the downtime involved to restore all your data – possibly days – and that’s a lot of lost productivity.  Plus, if word gets out that your data has been compromised, you may find confidence in your business plummets and your existing clients head elsewhere.  That $150 ransom may end up costing well over $150,000!

 

Prevent Ransomware Attacks on your Business

Keep your systems up to date: WannaCry took advantage of a flaw in older versions of Windows, one that was since patched by Microsoft. But to be protected, businesses had to be up to date with their patches AND be running a supported version of Windows. Delaying patches and updates puts your business at risk – we can help you update automatically.

Lock down employee computers: Very few staff will require full administrator access to your business network. The higher their level of permissions, the more damage a person can do – either accidentally with a whoopsie click, or by inadvertently installing malware. By locking down your employee computers, you have a better chance of containing a malware attack to non-vital systems. Our experts can design an access management plan that gives you best of both worlds: flexibility PLUS security.

Educate your workplace: Most employees believe they’re being cyber-safe but the reality is quite different. Many malicious links and embedded malware have become hard to spot in an instant – which is all it takes to click and regret. We can work with your staff to establish procedures around checking links for authenticity before clicking, awareness around verifying the source of attachments, and the importance of anti-virus scanning. We’ll help get the message through!

Have a solid backup plan: When ransomware hits, a connected backup = infected backup. Unfortunately, synced options such as Dropbox immediately clone the infected files, rendering them useless. The only safe backups will be the ones both physically and electronically disconnected, with systems designed to protect against attacks like this. Our experts can set you up with a backup system that makes recovery a breeze.

Be proactive: The best way to avoid the financial cost of a ransomware attack is to prevent it from happening in the first place. Remember, many businesses were able to watch WannaCry from the sidelines, completely unaffected and seizing opportunities while their competitors were down.

WannaCry Ransomware Explained: Is Your Business At Risk?

WannaCry Ransomware Explained: Is Your Business At Risk?

You’d be hard-pressed to miss last week’s biggest headline, the WannaCry cyber-attack sent shockwaves around the globe. Businesses of all sizes and even police departments found themselves crippled without warning.

Among the most prominent victims were many NHS hospitals in the UK, affecting up to 70,000 individual devices such as essential MRI scanners and blood-storage refrigerators. But by the time it hit the news, it was too late – either your system was protected, or it was infected. Here’s how it all went so wrong.

What is WannaCry?

The WannaCry cyber-attack was a type of malware (the collective name for computer viruses & bad juju) called ‘ransomware’. Just like the name suggests, it’s actually a demand for money. Like all ransomware attacks, WannaCry encrypts your files and holds them hostage until you pay. In this case, the price was set at $300, payable with internet currency Bitcoin, and you had 3 days to pay before it doubled. If you didn’t pay, the ransomware threatened to delete your files permanently. It’s yet unknown how much money the WannaCry hackers have earned with their latest attack, but you can be sure plenty of people have paid the ransom. Even the FBI recommends paying the ransom, especially if the ransomed files are of a sensitive nature or weren’t backed up.

 

How It Spread So Fast

It seems WannaCry may be a ‘computer worm’ that self-replicates and spreads, rather than a phishing attack that needs to be activated with a click. So far, no common trigger has been identified, as is normally the case with phishing links. WannaCry moved rapidly from system to system, spreading out through the entire network, including all connected backups and storage devices. At the same time, it spread out to infect other networks, who then spread it further, and so on. Given the nature of the internet, it was everywhere within hours.

Why Some Businesses Were Safe

WannaCry could ONLY infect systems that have fallen 2 months behind in their Windows updates. This is because it was created to take advantage of a specific vulnerability in Windows, one which Microsoft patched months ago. Without that patch, the ransomware could waltz right past the firewall, past the anti-virus and directly into the system (the NHS were reportedly running Windows XP – no longer supported). Those running Windows 10 or a fully patched, recent version of Windows were completely unaffected – the virus literally had no way in

It just goes to show the importance of staying up to date. We haven’t seen a second spike in WannaCry attacks yet, but that doesn’t mean there won’t be one. A quick update could protect your business from weeks of downtime and lost revenue, making attacks like this a non-issue.
