It’s a crime drama plotline you’ve seen a million times: Professional kidnappers demand a suitcase of unmarked bills in exchange for a hostage’s safe return. The tension builds as the clock ticks down. Victims sweat it out while they wait for the phone to ring.
Today’s extortionists have updated that age-old playbook for the digital era, substituting human hostages for precious files—from irreplaceable family photos to classified business documents—and demanding payment in Bitcoin in lieu of a duffel stuffed with banknotes.
In recent years, ransomware attacks have evolved from fringe threats to mainstream menaces—and they’ve also become more insidious. Today’s perpetrators first quietly pilfer your data before encrypting it, creating a dual threat: Pay us, or not only will you lose access, but we’ll leak everything we stole, from compromising photos to your company’s top-secret intellectual property. Cybersecurity experts call this ruthless approach “double extortion.”
The ransomware landscape of 2025 is poised to become even more treacherous now that AI is part of the picture. Thankfully, proactive measures—like investing in comprehensive cybersecurity solutions—can help you safeguard yourself, your family, and your business interests.
Here are a few steps every business and individual should take to fortify their defences.
Maintain Robust, Regular Backups
Perhaps the most powerful protection against ransomware is having secure, up-to-date backups of your most important or sensitive files (particularly crucial for business documents like financial records or customer databases). When devising a backup strategy, follow the “3-2-1 rule”:
Keep at least three copies of your data
Store backups on two different types of media
Keep one backup offsite (such as in cloud storage)
Critically, ensure some backups remain disconnected from your network—what security professionals call “air-gapped.” Without this separation, ransomware might encrypt your backups along with the originals.
Keep Software Meticulously Updated
If you’re the type to continuously click “remind me tomorrow” about pending software updates, it’s time to break that dangerous habit. Ensuring you’re using the latest version of operating systems and applications takes just minutes of your time—and you can even set updates or security patches to happen automatically at night when you’re not actively using your devices.
Don’t just focus on Windows or macOS when assessing system currency. Your browsers, PDF readers, and office software need regular updates, too—think of these as the side windows that burglars check after finding the front door locked. Set aside five minutes today to check every application on your devices for pending updates, and while you’re at it, tick those “automatically update” boxes wherever you find them.
Develop a Discerning Eye for Phishing Attempts
Phishing emails remain one of the primary delivery mechanisms for ransomware. These deceptive messages often masquerade as communications from trusted entities like banks, delivery services, or work colleagues in order to trick recipients into clicking malicious links or opening infected attachments.
Some of the most common tells that an email or text isn’t quite right include:
Urgent calls to action, specifically communications that demand immediate financial information
Messages containing grammatical errors or unusual phrasing
Suspicious attachments, especially executable files (.exe)
When in doubt, verify any unusual requests you receive via email or text through independent channels. For instance, if you receive an unexpected invoice or account alert, log in directly to the relevant website rather than clicking email links.
Implement Stringent Access Controls
The principle of “least privilege” involves giving users access only to the resources they absolutely need, and it can significantly limit ransomware’s reach. With this safeguard in place, if an account becomes compromised, the damage remains contained to a relatively small footprint.
For home users, this means using standard accounts for daily computing rather than administrator accounts. It’s also a good idea to create separate user accounts for different family members, and restrict app installation permissions where possible. For businesses, role-based access controls and regularly audited permissions are essential safeguards against widespread compromise.
Deploy Trusted Security Solutions
Confronting today’s advanced threats requires equally sophisticated protective measures. Modern security suites like Bitdefender Total Security include multiple layers of protection like:
Vulnerability assessments to spot security weaknesses
Network protection monitoring for suspicious connections
Behaviour-based detection to identify suspicious activities
Advanced Threat Defense designed specifically for ransomware
Bitdefender’s antiransomware protection specifically watches for file-encryption behaviours and can automatically back up targeted files. This helps ensure your most important data remains accessible even in a worst-case scenario.
Exercise Caution with Remote Connections
Remote Desktop Protocol (RDP) and other remote access tools have become frequent targets for ransomware operators. These services, when improperly secured, can provide direct system access to attackers—essentially leaving your digital front door wide open with a welcome mat for cybercriminals.
If you must use remote access tools, be sure to employ strong, unique passwords. Consider implementing multi-factor authentication (MFA) and using a virtual private network (VPN) to secure your connections to the internet. Limit RDP access to trusted IP addresses where possible, and finally—as with our advice above—keep remote access software updated. For businesses, consider requiring employees use a VPN connection before they can access remote desktop tools.
By implementing these protections and relying on security leaders like Bitdefender, you can stay ahead of threats—and stay out of the spotlight in the next straight-to-streaming cybercrime series.
