Hello there!

In today's digital world, computers, smartphones, and the internet have become integral parts of our daily lives. We use them to stay in touch with loved ones, manage our finances, and even store cherished memories like family photos and videos. But just like in the real world, there are bad actors online who want to take advantage of unsuspecting people. One of the ways they do this is through something called ransomware.

You might be wondering, "What is ransomware, and why should I be concerned about it?" Well, you're in the right place. This guide is designed especially for you—to help you understand what ransomware is, how it works, and most importantly, how you can protect yourself from becoming a victim.

So, grab a cup of tea or coffee, get comfortable, and let's dive into the world of ransomware together.

What Is Ransomware?

Imagine you come home one day and find that someone has changed the locks on your house. There's a note on the door demanding money to get the new key. That's essentially what ransomware does, but to your computer or files.

The Basics

Ransomware is a type of malicious software—or "malware" for short—that cybercriminals use to block you from accessing your own computer or files. They do this by encrypting your data, which means they scramble it so that it's unreadable without a special key. Then, they demand a ransom (usually money) in exchange for the decryption key that will unlock your files.

How It All Started

You might think ransomware is a new threat, but it's been around for quite some time. The first known ransomware attack happened back in 1989. A man named Dr. Joseph Popp, an evolutionary biologist, sent out floppy disks (remember those?) that appeared to contain educational content about AIDS. But once the disk was inserted into a computer, it would encrypt the files and demand a payment of $189 to unlock them.

Since then, ransomware has evolved dramatically. With the advent of the internet and digital currencies like Bitcoin, it's become easier for cybercriminals to target victims worldwide and collect payments anonymously.

Why It's a Big Deal Today

Ransomware attacks have increased significantly over the years. They've targeted individuals, businesses, hospitals, and even government agencies. During the COVID-19 pandemic, for example, some hospitals were hit with ransomware, making a critical situation even worse.

The reason ransomware is so prevalent today is that it's profitable for cybercriminals. Some have made millions of dollars from ransom payments. And with tools readily available online, even people without advanced technical skills can launch ransomware attacks.

Why Should Seniors Care About Ransomware?

You might be thinking, "I'm just an ordinary person. Why would anyone target me?" Well, unfortunately, seniors are often seen as attractive targets for several reasons:

• Less Familiarity with Technology: You may not have grown up with computers and the internet, so you might be less aware of the latest threats.
• Valuable Information: Your computer likely contains valuable personal information—family photos, financial records, medical information—that you wouldn't want to lose.
• Trusting Nature: Seniors are often more trusting, which cybercriminals exploit through deceptive emails and calls.

Understanding ransomware is the first step in protecting yourself and ensuring that your personal and sensitive information remains secure.

How Does Ransomware Spread?

Knowing how ransomware spreads can help you avoid falling victim to it. Here are some common ways ransomware can find its way onto your computer:

Phishing Emails

Phishing is when cybercriminals send you emails that look like they're from someone you know or a company you trust. These emails often contain:

• Malicious Links: Clicking on these can download ransomware onto your computer.
• Infected Attachments: Opening these can trigger a ransomware installation.

Example: You receive an email that looks like it's from your bank, asking you to click a link to verify your account. The link takes you to a fake website that installs ransomware.

Malicious Websites and Ads (Malvertising)

Malvertising is when attackers embed malware in online advertisements. You might encounter these on websites you visit regularly.

• No Click Needed: Sometimes, just loading the webpage is enough for the ransomware to download.
• Fake Ads: These ads might promise something enticing, like a prize or a discount, but clicking on them can infect your computer.

Example: While reading an online news article, an ad pops up saying you've won a gift card. Clicking on it downloads ransomware.

Exploit Kits

These are tools that cybercriminals use to find vulnerabilities in your computer's software.

• Outdated Software: If your operating system or applications aren't updated, they may have security holes.
• Automatic Infection: Visiting a compromised website can allow the exploit kit to install ransomware without your knowledge.

Example: You're using an old version of your web browser, and you visit a site that has been compromised. The ransomware installs itself automatically.

Drive-By Downloads

This occurs when you visit a website that automatically downloads malware onto your computer.

• No Interaction Needed: You don't have to click or download anything manually.
• Common on Unsecured Websites: These are often sites that don't have proper security measures in place.

Example: You search for a recipe and click on a link that takes you to a website loaded with malware.

Types of Ransomware

Understanding the different types of ransomware can help you recognize if you're being targeted.

Filecoders (Encryptors)

• What They Do: Encrypt your files so you can't access them.
• How They Work: They search your computer for specific file types (documents, photos, videos) and encrypt them.
• Ransom Demand: They ask for payment in exchange for the decryption key.

Example: The infamous CryptoLocker ransomware encrypts your personal files and demands payment to unlock them.

Screen Lockers

• What They Do: Lock you out of your computer entirely.
• How They Work: They display a full-screen message that blocks all other functions.
• Ransom Demand: Often impersonate law enforcement, claiming you've broken the law and must pay a fine.

Example: A message appears, supposedly from the FBI, stating that illegal activity was detected on your computer and you must pay a fine to regain access.

Doxxing Threats

• What They Do: Threaten to release your personal information publicly.
• How They Work: They gain access to sensitive data like passwords, financial information, or personal photos.
• Ransom Demand: Payment is demanded to prevent the information from being leaked.

Example: You receive an email stating that the attacker has your email contacts and will send embarrassing information to them unless you pay.

Scareware

• What They Do: Try to scare you into thinking there's a problem with your computer.
• How They Work: They display alarming messages claiming your computer is infected or has errors.
• Ransom Demand: Ask you to pay for a service or software to "fix" the non-existent issues.

Example: A pop-up alerts you that your computer has numerous viruses and you need to pay for a cleanup tool immediately.

How Ransomware Attacks Work

Let's walk through a typical ransomware attack so you can see how the pieces fit together.

Step 1: Infection

The attack begins when you inadvertently download the ransomware:

• Opening an Email Attachment: An innocent-looking document turns out to be malicious.
• Clicking a Link: Redirects you to a website that downloads the ransomware.
• Visiting a Compromised Website: The site automatically downloads the ransomware without your knowledge.

Step 2: Encryption or Lockout

Once the ransomware is on your computer, it gets to work:

• Encrypting Files: It searches for and encrypts personal files like documents and photos.
• Locking the Screen: It might lock your entire computer, preventing any use.

Step 3: Ransom Demand

A message appears, typically with:

• Instructions: How to make the payment, usually in Bitcoin or another cryptocurrency.
• Deadline: A time limit after which the ransom may increase or your files may be lost forever.
• Threats: Warnings about what will happen if you don't comply.

​

Step 4: Potential Outcomes

• Paying the Ransom: Not recommended. There's no guarantee you'll get your files back, and it encourages criminals.
• Seeking Help: From professionals or law enforcement.
• Restoring Backups: If you have backups, you can restore your system without paying.
