The cost of a ransomware attack goes way beyond the ransom itself — and most organizations don't find that out until it's too late. In this episode of The Backup Wrap-up, W. Curtis Preston (Mr. Backup) and co-host Prasanna Malaiyandi sit down with Dr. Mike Saylor of Black Swan Cybersecurity to walk through every category of cost that hits when ransomware strikes.

The case that kicks everything off: UVM Health Network, October 2020. Over 1,300 servers encrypted, staff forced back to paper records, patient care disrupted for weeks. Total tab? Over $63 million — and they never paid the ransom.

From there, we go category by category: people costs (overtime, third-party IR firms, emergency hardware), lost business revenue, regulatory fines, reputational damage that doesn't wash off, staff burnout and resignations, supply chain chaos, payment processor shutdowns, and cyber insurance fine print that can leave you holding the bag even when you think you're covered.

We also cover what you should be doing right now — before any of this happens to you. Starting with a Business Impact Analysis, which Mike argues most small-to-medium businesses can knock out in one to three weeks. Knowing what a downed system costs you per hour is exactly the information that gets you budget from leadership and a plan that actually works when the feces hits the rotary oscillator.

Polymorphic malware is the kind of threat that changes its own code — its signature, its behavior, even the command-and-control server it reports to — specifically so your antivirus can't catch it. In this episode, Dr. Mike Saylor of Black Swan Cybersecurity joins Prasanna and me to break down exactly how this works, why signature-based detection keeps losing the race, and what defenders actually need to do differently.

Mike walks us through ViraLock, one of the most well-known early examples of polymorphic malware, and explains the gap between infection and detection that attackers exploit. We also get into the difference between polymorphic and metamorphic malware — and metamorphic is a lot scarier. Then we cover waterhole attacks, a red team story that will make you rethink how fast attackers can own a network, and what behavioral detection looks like when it's actually working.

If you thought keeping your antivirus updated was enough, this episode is going to change your mind.

A PyPI software supply chain attack hit LiteLLM — a library pulled into developer environments 97 million times a month — and if you use it, you may already be compromised. This wasn't a fake package or a typo-squatting trick. Attackers stole real credentials, published malicious code as the real thing, and walked out with SSH keys, cloud credentials, Kubernetes tokens, API keys, and more — all encrypted and sent home before anyone knew what happened.

I'm doing something I've never done before: an emergency episode, recorded and published immediately because this is that serious. I brought in Dr. Mike Saylor, co-author of our book Learning Ransomware Response and Recovery, and my co-host Prasanna Malaiyandi to break down exactly what happened, how to find out if you were hit, and what you need to do to protect yourself going forward.

We open with a story from 1982 that perfectly captures what this attack really is — getting poisoned by something you trusted completely. That framing matters. This wasn't a failure of the library. It was a failure of the supply chain. And it can happen again.

Fileless malware is one of the most dangerous attack types out there — it never writes to your hard drive, lives entirely in RAM, and can steal your credentials before your antivirus has any idea it's there. In this episode, I bring in Dr. Mike Saylor — my co-author on Learning Ransomware Response & Recovery — to break down exactly how this attack works, why it's so hard to detect, and what you can actually do to protect yourself.

Mike walks us through how fileless malware hides in memory, how bad guys maintain their foothold even after a reboot by modifying registry keys or rewriting the operating system itself, and why the ArcGIS attack is a perfect real-world example — attackers sitting undetected inside a network for two years. We also get into MFA, specifically why a lot of MFA setups are done wrong, why passkeys are the better answer, and when it's time to bring in an EDR or XDR tool.

Fair warning: the action items here are a bit more advanced than our usual stuff. Think of this as the 401k conversation — don't have it before you've built your emergency fund. But this is stuff you absolutely need to know.

A living off the land attack is one of the sneakiest techniques in a ransomware operator's playbook — and in this episode, Dr. Mike Saylor breaks down exactly what it is, how it works, and what your organization can actually do about it.

Instead of bringing their own tools into your environment (which might trip your alarms), attackers just use what's already there. PowerShell. WMI. RDP. The same tools your admins run every single day. To your monitoring systems, it looks completely normal. That's the whole point.

Mike and Curtis cover why attackers prefer your tools over their own, how recon can quietly run for 30 to 90 days before the attack goes loud, and what defenders can actually do about it — removing admin privileges, system hardening, golden images, application whitelisting, and free tools like Nmap and Wireshark. There's also a match.com story involving organized crime and a wooden casket on someone's front porch that you really don't want to miss.

Password manager vulnerabilities aren't just about bad code — and a new research paper out of Zurich just proved it. Researchers analyzed three of the most popular password managers and found fundamental design flaws baked into the very architecture that's supposed to keep your credentials safe. Curtis and Prasanna break it all down and tell you what to do about it.

If you've ever been that person who asks "but what if the password manager gets hacked?" — this episode is for you. And if you haven't been asking that question, you probably should start. A research team looked at LastPass, Bitwarden, and Dashlane — products with a combined 60 million users representing roughly 23% of the password manager market — and what they found wasn't sloppy programming. It was something harder to fix: architectural problems at the core of how encrypted vaults work.

Curtis walks through how the zero-knowledge encryption model works, why the vault recovery process creates an inherent trust problem, and why the researchers were able to exploit that trust by impersonating the server during vault recovery. Prasanna adds another layer — the field-level encryption issues inside the vaults themselves, where there's no strong verification that data hasn't been manipulated. It's not theoretical. It's a real attack surface.

The good news? Curtis still believes password managers are the right tool for today — better than sticky notes on a monitor (yes, he saw that in real life) and better than reusing passwords. But he's also clear that passkeys are the right direction for the future, even if the current implementation is still a little rough around the edges.

What is an initial access broker — and why does it matter to your organization? In this episode, W. Curtis Preston and Prasanna Malaiyandi are joined by Dr. Mike Saylor of Black Swan Cybersecurity to break down the role of the initial access broker in today's ransomware attacks.

Most people picture ransomware as a single bad guy with a keyboard. The reality is way scarier. There's an entire criminal supply chain out there, and the initial access broker is the specialist at the front of it. These are the people who do nothing but break in — stealing credentials, exploiting vulnerabilities, hijacking sessions — and then sell that access to other criminals who do the dirty work. Dr. Mike Saylor walks us through a real case study from 2024 where an employee's personal Gmail account — with a Google Docs folder literally named "passwords" — became the entry point for a corporate ransomware attack months later. This stuff is real, it's happening constantly, and most organizations have no idea how exposed they are.

We cover what IABs target, how they package and sell access, what "coincidental passwords" are and why they're so dangerous, and what practical steps you can take today to make your organization a harder target.

Ransomware as a service has turned cybercrime into a franchise business — and in this episode, Dr. Mike Saylor and I break down exactly how it works, who's buying, and why the buyer might end up as the patsy.

If you thought ransomware was just a lone hacker writing code in a basement, this episode is going to change how you think about it. Ransomware as a service means that today, literally anyone — no technical skills required — can pay someone to launch a ransomware attack on their behalf. You hand over the money, tell them what you want, and sit back and watch your crypto wallet. That's it. No portal. No dashboard. No login. Just a chat on the dark web through the TOR network and a prayer that they actually do what you paid for.

Dr. Mike Saylor walks us through the full criminal ecosystem — from the initial access brokers who collect and sell validated email addresses, to the botnet operators who rent out millions of compromised computers by the hour, to the affiliate programs that tie it all together. We cover the franchise model, the "no honor among thieves" reality of these transactions, and why the person who buys into ransomware as a service might just end up as law enforcement's fall guy.

This is one of those episodes where the more you learn, the more you realize how much the threat picture has changed — and why your backups are more important than ever.
