Ransomware targets organizations of every size, whether you run a five-person accounting firm or the backbone of a nation's healthcare network. In early 2024, hackers from the ALPHV/BlackCat group logged into UnitedHealth’s Change Healthcare unit using a compromised password. The attackers reportedly stole roughly six terabytes of patient data, which forced Change Healthcare to take its network offline. The impact was instant as pharmacies and clinics across the US couldn't fill prescriptions or process insurance payments. UnitedHealth paid a $22 million Bitcoin ransom to speed up recovery, but restoring operations still took months, and the hackers kept the money regardless. That's the threat you're up against, ransomware doesn't just lock your files, it can freeze the systems your customers depend on, and paying doesn't guarantee you get any of it back.

What exactly is Ransomware?

At its core, ransomware is malicious software that encrypts your files and holds them hostage until you pay. The threat has moved well past simple "lock and pay" schemes. Attackers now routinely steal your data before encrypting it, then threaten to leak or sell it if you don't pay, a tactic known as double extortion. Some groups pile on denial-of-service attacks or contact your customers directly to apply more pressure, what researchers call triple or quadruple extortion. Once the encryption runs, you'll typically find files renamed with extensions like .locked or .encrypted, with a ransom note dropped into every affected folder.

How a Ransomware Attack Actually Happens

Most incidents involving ransomware follow a similar sequence, whatever the size of the target organization. This sequence are as follows:

1. 1.Initial access: This is how the attackers break into your network. They might exploit a security vulnerability, trick you with a phishing email, or use stolen credentials to slip right through the front door.
2. 2.Establishing a foothold: Once inside, they set up camp. The attackers install a backdoor or remote access tool and quietly disable any security alerts they can find. This ensures they can get back in even if you happen to close their original entry point.
3. 3.Reconnaissance: Before making a move, the attackers map out your network. They spend time figuring out where your most critical systems, like domain controllers and backup servers, are located.
4. 4.Lateral movement: Using what they learned, they move through your environment, jumping from system to system. They escalate their permissions until they gain admin-level access across as much of your network as possible.
5. 5.Data exfiltration: Before they encrypt a single file, the attackers quietly copy your most sensitive data and send it to their own servers. This gives them extra leverage to extort you later, threatening to leak the stolen information if you don't pay up.
6. 6.Deployment and encryption: Now the actual ransomware goes off. To make sure you can't easily recover, they first disable your backups, shadow copies, and endpoint protection. Then, they lock down your files, leaving you with no recovery options before you even see a ransom note.
7. 7.Extortion: Finally, you find the ransom note. You're given a countdown and threatened with the public release of your stolen data if you don't pay. If any negotiation happens, it starts here.

What Ransomware Actually Costs You

Ransomware rarely stays as your IT team's problem. IBM 2025 Cost of a Data Breach Report, studied 600 organizations across 17 industries, and if attackers go public with the extortion, you're looking at an average total cost of $5.08 million, well above the $4.44 million average for breaches in general. That $4.44 million baseline actually dropped 9% year over year, mostly because more organizations are catching and containing breaches faster. Ransomware didn't get the memo. It sits in its own, far pricier lane, and if you skip looping in law enforcement, you'll likely pay more for it, even though fewer victims are bothering to report attacks at all.

Sophos surveyed organizations for its 2026 State of Ransomware report and found the average recovery cost, excluding any ransom paid, at $1.7 million. The report also found that 56% of ransomware attacks resulted in data encryption, while 48% of organizations with encrypted data paid the ransom.

How You Can Protect Your Business from Ransomware

The good news is that ransomware isn't unstoppable, and you don't need an unlimited security budget to meaningfully reduce your risk. Here's where to focus your energy:

1. 1.Enforce multi-factor authentication.
2. 2.Regularly Back up your data and test the backup restoration.
3. 3.Apply security patches consistently.
4. 4.Train your people to recognize phishing emails and social engineering in general.
5. 5.Write an incident response plan before you need one.
6. 6.Think hard before paying a ransom.

Conclusion

Ransomware isn't going away, and pretending it only happens to someone else is no longer a safe assumption for any business, regardless of size. What you can control is how prepared you are, the strength of your defenses, the readiness of your team, and the partners you have on standby when things go wrong. Taking ransomware seriously today, before you're staring at a lock screen, is the difference between a close call and a closed business. With the right precautions in place, and the right expertise behind you, you can meet this threat with confidence instead of fear.

How A&D Forensics Can Help

A&D Forensics supports you at every stage of a ransomware incident. Before an attack, our Vulnerability Assessment and Penetration Testing (VAPT) finds the gaps an attacker would exploit, before they do. During an incident, our blockchain and digital forensics helps you and law enforcement follow where stolen funds and data are moving. After an attack, our incident investigation reconstructs how the attackers got in, what they touched, and what needs to change and through our security operations consultation, covering playbook engineering and data recovery planning, we help you build the kind of resilience that makes your business a harder target the next time around.
