The Backup Wrap-Up

What is data deduplication, and why does Curtis call it the single most important development in backup over the last 30 years? In this encore episode, W. Curtis Preston and Prasanna Malaiyandi break down exactly how dedupe works, why it's not the same as compression, and why the fine print of your dedupe domain determines how much storage you actually save. This episode originally aired as part o...

Phishing-resistant MFA could have stopped a Chinese state-sponsored threat actor from spending over a year inside North American academic and medical research networks — and we're going to tell you exactly how it happened and what you need to do about it. A group called UNC5608, tracked by Google's Threat Intelligence Group (GTIG), exploited a vulnerability unique to REDCap — a research data platf...

California election fraud claims are flooding social media — and most of them fall apart under basic scrutiny. In this follow-up episode, longtime San Diego County poll worker W. Curtis Preston tackles the wave of viral fraud allegations head-on, with sources so you can check his work yourself. Topics covered: the LA mayoral race "statistically impossible" surge for Nithya Raman, the AP reporting...

California election counting has confused — and frankly ticked off — a lot of people, and I get it. I'm W. Curtis Preston, I've worked every California election since the 2016 presidential primary, and I've managed the polls at multiple elections here in San Diego County. This episode, I'm going solo to explain exactly what's going on, why it takes so long, what the "red mirage" actually is, and w...

Basic cyber hygiene — patch management, password management, and MFA — is responsible for stopping roughly 90% of the ransomware attacks that could hit your organization. This episode is the overview: what those three things are, why they matter, and what happens when you skip them. WannaCry infected over 200,000 systems worldwide. A patch existed. People just hadn't applied it. Rackspace lost an...

Claude deletes a company — and the internet immediately blamed the AI. But this story is really about backup design, credential management, and least privilege. An AI coding agent running Claude via Cursor deleted PocketOS's entire production database and all its backups in nine seconds. One bad design decision at a time, a startup built itself a disaster waiting to happen. Claude just happened to...

Honeypots and canary files are two of the most underused tools in cybersecurity — and in this episode, Dr. Mike Saylor and I break down exactly how they work and why you should be using them. The short version: they're tripwires. They tell you a bad guy is poking around your network before anything gets encrypted. Mike walks through his layered security analogy, explains the three different ways o...

Network segmentation to prevent ransomware isn't just a nice-to-have — the UCSF ransomware attack proves it's what separates a contained incident from a catastrophe. UCSF got hit. Their segmented network kept the damage from spreading across their entire operation. That's the difference we're talking about in this episode. Dr. Mike Saylor — my co-author on Learning Ransomware Response and Recovery...

Stop Using VSS as a Backup Before Ransomware Deletes Your Shadow Copies Ransomware deletes shadow copies using your own built-in Windows tools against you — and if VSS was your backup plan, you just found out the hard way that it wasn't. In this episode, W. Curtis Preston (Mr. Backup), Prasanna Malaiyandi, and Dr. Mike Saylor break down exactly what shadow copies are, why they don't qualify as a r...

Ransomware sanctions are something most companies never think about — until they're staring down a ransom demand from a group the US government has already put on a sanctions list. In this episode, Dr. Mike Saylor walks us through a real incident involving a construction company, hundreds of millions in active contracts, and the Lazarus Group — a North Korean state-sponsored threat actor. Before t...

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...

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...

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 en...

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 yo...

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...

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...

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 crimin...

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...

The cryptolocker virus was the attack that turned ransomware from a nuisance into a full-blown criminal industry — and in this episode of The Backup Wrap-up, we break down exactly how that happened. W. Curtis Preston (Mr. Backup) sits down with co-host Prasanna Malaiyandi and cybersecurity expert Dr. Mike Saylor to trace the full evolution of ransomware and explain why CryptoLocker was the turning...

A history of ransomware is more than just dates and names—it's the story of how criminals evolved from mailing infected floppy disks in 1989 to running billion-dollar enterprises that cripple entire organizations. On this episode of The Backup Wrap-up, I sit down with Dr. Mike Saylor, my co-author on "Learning Ransomware Response and Recovery," to trace this evolution from the AIDS Trojan to today...

Understanding how ransomware works is critical for anyone responsible for protecting their organization's data. In this episode of The Backup Wrap-up, we examine the five core objectives that drive nearly every ransomware attack - from initial access through the final ransom note delivery. I'm joined by my co-author Dr. Mike Saylor as we kick off what's going to be a comprehensive series on our ne...

Disk backup security is the weak link that ransomware attackers exploit every day—and most backup admins don't even realize it. In this episode, Curtis and Prasanna examine how the move from tape to disk-based backups created an unintended security gap that threat actors now target as their first priority. The transition to disk brought real benefits: deduplication made storage affordable, replica...

What is ransomware, and why does it remain the number one threat to businesses of all sizes? In this episode of The Backup Wrap-up, W. Curtis Preston and Prasanna Malaiyandi break down the fundamentals of ransomware attacks and explain why the question "what is ransomware" still gets searched tens of thousands of times each month. We cover the two main types of ransomware attacks: traditional encr...

What's your real backup TCO? Most organizations focus on software licenses, hardware, and cloud storage when budgeting for backup infrastructure. But those are just the visible costs. The true backup TCO includes something far more expensive: the humans managing it all. In this episode, Curtis and Prasanna break down the complete picture of backup costs. They explore why soft costs—the labor, the...

Ransomware attacks on backups have reached epidemic levels, with 96% of attacks now targeting backup infrastructure. In this episode of The Backup Wrap-up, Curtis Preston and Prasanna Malaiyandi break down the alarming statistics and explain why cybercriminals have made your recovery systems their primary target. The math is simple: if attackers destroy your backups, you're far more likely to pay...
