All Together Now

Our show is all about heroes making great strides in technology. But in InfoSec, not every hero expects to ride off into the sunset. In our series finale, we tackle vulnerability scans, how sharing information can be a powerful tool against cyber crime, and why it’s more important than ever for cybersecurity to have more people, more eyes, and more voices, in the fight. Wietse Venema gives us the story of SATAN, and how it didn’t destroy the world as expected. Maitreyi Sistla tells us how representation helps coders build things that work for everyone. And Mary Chaney shines a light on how…

Invisible Intruders
What began as a supposed accounting error landed Cliff Stoll in the midst of database intrusions, government organizations, and the beginnings of a newer threat—cyber-espionage. This led the eclectic astronomer-cum-systems administrator to create what we know today as intrusion detection. And it all began at a time when people didn’t understand the importance of cybersecurity. This is a story that many in the infosec community have already heard, but the lessons from Stoll’s journey are still relevant. Katie Hafner gives us the background on this unbelievable story. Richard Bejtlich outlines…

Ruthless Ransomers
It’s a strange situation when someone can hold something hostage from halfway around the world. It’s tragic when your own pictures and files are remotely encrypted. But when it’s a hospital’s system? Ransomware becomes a problem about life or death. Eddy Willems recounts his involvement in defeating an early ransomware attack that targeted AIDS researchers. At the time, there was a way to discover the encryption key. But as Moti Yung warned, asymmetric encryption would change everything. In the years since, ransomware attacks have become much more popular—thanks in part to the rise of…

Menace in the Middle
All communication leaves the possibility for crossed wires. And as we become more connected, there’s a chance for those with ill intentions to steal our information and meddle in our daily lives—with devastating results. Smriti Bhatt breaks down the complexity behind machine-in-the-middle attacks. Johannes Ullrich tells us why we shouldn’t always trust that free WiFi. And the “father of SSL” Taher Elgamal notes that while cryptography can address the increasingly sophisticated nature of malware, there are no safe bets in security. If you want to read up on some of our research on machine in…

Dawn of the Botnets
Overwhelming numbers are scary—even in the best of circumstances. You can plan for them, build up your defenses, and do everything imaginable to prepare. But when that horde of zombies hits, their sheer numbers can still cause devastation. Botnets are digital zombie hordes. Jamie Tomasello recounts the scale of the Bredolab botnet—and the many malicious kinds of missions it carried out. Martijn Grooten explains how botnets work, and why they can be so difficult to permanently dismantle. And Darren Mott shares some of the successes the FBI had in rounding up some of the world’s most prolific…

Lurking Logic Bombs
Logic bombs rarely have warning sounds. The victims mostly don’t know to expect one. And even when a logic bomb is discovered before it’s triggered, there isn’t always enough time to defuse it. But there are ways to stop them in time. Paul Ducklin recounts the race to defuse the CIH logic bomb—and the horrible realization of how widespread it was. Costin Raiu explains how logic bombs get planted, and all the different kinds of damage they can do. And Manuel Egele shares some strategies for detecting logic bombs before their conditions are met. If you want to read up on some of our research…

Terrifying Trojans
Sometimes a fun game, a friendly email, or an innocuous link can be the most convenient place for an enemy to hide. And its prey is none the wiser—until it strikes. The trojan horse uses many layers of deception to do damage. The ingenuity of these attacks keeps an alarming pace with the technology we use every day. But as long as we stick to trusted sites and sources, we can better the odds against those who use our trusting nature against us. Steve Weisman tells us about how trojans still keep security professionals on the defensive. Josephine Wolff details how these attacks have evolved,…

Relentless Replicants
Computer viruses and worms haunt the internet. They worm their way into a system, replicate, and spread again. It’s a simple process—with devastating consequences. But there’s a whole industry of people that rose up to fight back. Craig Schmugar recalls how he and his team responded to MyDoom, one of the fastest-spreading worms ever. Dr. Nur Zincir-Heywood reveals the inner workings of viruses and worms, and how they draw their names from the world of biology. And security expert Mikko Hypponen shares advice on avoiding malware. But he also warns that we’re in an arms race against malware…

Command Line Heroes Season 9: The Horrors of Malware
Malware haunts us all. Viruses, worms, trojan horses, and the harm they do often corrupts the promise of the internet. But the world of computing continues to grow. Though it’s changed us forever, malware hasn’t stopped us from connecting. Season 9 of Command Line Heroes is the culmination of the show. We focus on security and the people who, every day, face the monsters of the digital world. They disinfect computers from viruses, defuse logic bombs, and dismantle botnets. But they can’t do it alone. It’ll take all of us working together to make the world a safer place. The first episode…

Robot as Vehicle
Self-driving cars are seemingly just around the corner. These robots aren’t quite ready for the streets. For every hyped-up self-driving showcase, there’s a news story about its failure. But the good news is that we get closer every year. Alex Davies steers us through the history of autonomous vehicles. Alex Kendall maps the current self-driving landscape. And Jason Millar takes us under the hood of these robots’ computers to better understand how they make decisions. If you want to read up on some of our research on self-driving cars, you can check our all our bonus material over at…

Robot as Threat
When a robot goes bad, who is responsible? It’s not always clear if the user or the manufacturer is liable when a robot leaves the lot. Human behavior can be complex—and often contradictory. Asking machines to interpret that behavior is quite the task. Will it one day be possible for a robot to have its own sense of right and wrong? And barring robots acting of their own accord, whose job is it to make sure their actions can’t be hijacked? AJung Moon explains the ethical ramifications of robot AI. Ryan Gariepy talks about the levels of responsibility in robotic manufacturing. Stefanie Tellex…

Humans as Robot Caretakers
HitchBOT was an experiment in stewardship: A small, rudimentary robot unable to move on its own, depending on the kindness of passersby to help it along its journey. Until it met an untimely end. Trust is a two-way street, and because robots are not powered by their own moral code, they rely on humans to supply both empathy and support. Dr. Frauke Zeller shares HitchBOT’s origin story. Eli Schwartz recounts his heartbreak upon learning what happened in Philadelphia. Dr. Julie Carpenter analyzes why it all went down. And Georgia Guthrie epitomizes the outpouring of sympathy that followed.…

Robot as Body
For years, prosthetic technology focused on form over function, on masking lost limbs, rather than agency and usability. But things are changing. Innovations in robotics are giving more people more options, with lower thresholds of entry—and lower price tags, too. Tilly Lockey takes us through her journey with prosthetic arms. Brian Schulz gives some history of mechanical prosthetics, and what it means for people to reach embodiment with their devices. Tyler Hayes talks about the software that made advancements in assistive technology possible. Charlie Kemp discusses his work building…

From Compiler: Do We Want A World Without Technical Debt?
Who says tech talk has to be boring? On Compiler, we dig into tech topics big, small, and strange. We talk to people who know the code, and bring their perspectives back to you. Intrigued? Here's a preview episode. Software development teams often reach a crossroads. Should they perform maintenance and address bug issues, or add new features to satisfy users? The former isn’t as exciting, but sometimes the most important work is invisible to those who reap the benefits. For now, the project has been released, and everyone wants to celebrate. But there’s an elephant in the room, one that…

Robot as Humanoid
It’s hard enough to make a functional, reliable robot. Many people also want to make those robots in our image. That’s a tough needle to thread. Often, the most efficient design isn’t the most human-like one. But that isn’t stopping us from reaching for those humanoid robots. Professor Shigeki Sugano argues in favor of creating human-shaped robots. But it’s such an enduring challenge, we’ve come up with a name for it: the uncanny valley. Evan Ackerman walks us through the uncanny valley’s treacherous terrain. Deanna Dezern shares how she’s connected to her robot companion. And Dor Skuler…

Robot as Maker
One of the first functional robots appeared on TV in 1966. That’s earlier than some of us expect. The Unimate’s televised premiere sparked the world’s imagination. It represented a host of possibilities. Those possibilities, however, also implied a coming competition that would last for decades. Dag Spicer tells the story of the Unimate, the first industrial robot—and how little the American public trusted it. But that distrust wasn’t universal. Tomonori Sanada explains how the Unimate was received very differently in Japan. Joe Campbell describes the dangers of working alongside industrial…

Robot as Software
Building a physical robot isn’t cheap—even when it’s the final version. Designing a robot and testing it over and over again? That takes a lot of tries. And likely more than a few failures on the way to success. Luckily, simulation software is reducing the scrap heap—and bringing down the costs of building robots from the ground up. Kevin Knoedler shares how simulation software allows him to program and design robots from home. And even though he doesn’t have the budget or support of major research institutions like DARPA, his robots still end up winning major competitions. Evan Ackerman…

Robot as Servant
The 1980s promised robotic servants were in reach. They’d clean up our houses. Bring us drinks. Usher in an era of leisure. We didn’t get robot butlers. But if we look around, we’ll find an army of robotic servants already automating away domestic drudgery. Richard Rowland recounts the extent to which Androbot over-promised on its ability to build a robot servant. 40 years later, we still don’t have robot maids. Monroe Kennedy III walks us through the complexities of seemingly simple tasks. To make things more difficult, each attempt to build a robot had to build the hardware AND write the…

Command Line Heroes Season 8: Broadcasting the Robot Revolution
Robots have a special place in our imaginations. Writers, artists, directors, and more have shown how robots can change our world—for better or far, far worse. In the real world, robots seem a long way off. But are they? Season 8 of Command Line Heroes is all about the rise of the robots. They just may not be what you expect. We meet the first industrial robot, take a journey through the uncanny valley, and investigate a possible robot crime. Season 8 covers the robots that are in our midst—and the determined dreamers who bring them to life. The first episode drops September 7, 2021. Follow…

After the Bubble
The Y2K bug generated a lot of fear, but all that hype fizzled when the new millennium didn’t start with a digital apocalypse. It turns out that fear was just aimed at the wrong catastrophe. While plenty were riding high on the rise of the internet beyond the Y2K scare, another disaster had been brewing since 1995—and would bring them back down. But the dot-com bubble wasn’t the end. The internet was here to stay. Not long after the turn of the millennium, the dot-com economy collapsed. Peter Relan points to the flawed business plans that fueled the dot-com bubble, and how many entrepreneurs…

The World of the World Wide Web
1995 laid the groundwork for a truly global World Wide Web. But not every country took the same path to connecting to the internet. Some resisted, wanting to create their own version. Others had to fight for access, not wanting to be left behind. And while we made huge strides in connecting the world in those early years, we still have a long way to go. Julien Mailland recounts the rollout of France’s Minitel service—how it was years ahead of the internet, but eventually lost its lead. Steve Goldstein explains what was involved in building the infrastructure to expand the NSFNET beyond the…

Looking for Search
The web was growing quickly in the ‘90s. But all that growth wasn’t going to lead to much if people couldn’t actually find any web sites. In 1995, an innovative new tool started crawling the web. And the search engine it fed opened the doors to the World Wide Web. Elizabeth Van Couvering describes trying to find websites before search engines, and how difficult it was becoming in the early ’90s to keep track of them all. Louis Monier talks about having to convince others how important search engines would become—and he showed them what a web crawler could do. Paul Cormier recounts taking the…

Shopping for the Web
We put a lot of trust into online shopping: sharing our names, addresses, and handing over money. In return, we have faith that the purchased item appears at our doorstep in a few days or weeks. That trust didn’t come easily. In 1995, we took our first steps out of the brick and mortar store to load our digital shopping cart. Robert Spector reveals how Amazon.com’s business foundations are in data—and being early to the internet. Sandeep Krishnamurthy recounts the rise of eBay. Angela Robinson describes the technology that makes secure transactions and trustworthy e-commerce possible. Kartik…

Web UX Begins
Looking at the internet in 1995 is like looking back at awkward grade school yearbooks—all the weirdness and flaws stand out in stark contrast to what it’s grown into since. And web design took awhile to become a career—but it got a big boost in 1995. When the Batman Forever website launched to promote the movie, it showed people what was possible on the web. And it forever changed what we’d expect from a website. Jay Hoffmann describes the quirky designs of the early web. Richard Vijgen explains how we went from a lack of conventions to a homogenized web. Jeffrey Zeldman recounts building…

A Language for the Web
The Hypertext Markup Language (HTML) gave everyone a foundation for building and viewing the World Wide Web. In 1995, its standardization led to dominance. Its simplicity helped it spread. And its solid common foundation helped shape the internet. Dr. Belinda Barnet explains what kind of framework was initially needed to build and navigate the Web. Jeff Veen describes the three ingredients Tim Berners-Lee combined to create HTML: the ideal language for the Web. Gavin Nicol recounts the need to standardize the quickly-growing language. And Gretchen McCulloch points out how HTML instills an…

From NSF to ISP
1995 was the year that ISPs became the dominant gateway to the information superhighway. But how’d we go from ARPANET all the way to that? It turns out, none of it would have happened without a team of intrepid engineers at the University of Michigan. Marc Weber tells us how a tension between academics and the military set the next evolution of the ARPANET. Douglas Van Houweling discusses the work his MERIT team did at the University of Michigan to build the national backbone of the NSFNET. Elise Gerich, MERIT’s systems manager, talks about how they made the leap from a T1 connection to a T3…

Connecting the Dot-Com
The year is 1995. The internet starts going mainstream and the dot-com bubble begins its rapid inflation. But 10 years before all of this, a small team of systems administrators made a seemingly simple decision that would turn out to have a monumental impact on these events and would set the course of the internet for the foreseeable future. Dr. W. Joseph Campbell sets the stage for our season on the internet in 1995. Claire L. Evans explains how hard it was to find anything on the early internet. One team was charged with compiling that information in the early days of the ARPANET.…

Command Line Heroes Season 7: Internet Class of '95
The internet’s been around for awhile now. And it’s safe to say that it’s changed much of our daily lives. But not so long ago, there were few people who realized how transformative the internet would become. Season 7 of Command Line Heroes looks back at those few who saw the internet’s early potential and forever shaped it during its most formative year: 1995. From the origins of e-commerce, to web design, to HTML, to the infrastructure holding it all together around the world, this season highlights the heroes who turned the nascent internet into the vital global network we know today.

Arlan Hamilton: The Investor Who's Opening Doors
If you think hard work is enough to guarantee success, you haven’t been listening. All season long, we’ve profiled Black inventors who haven’t quite been given their due. Arlan Hamilton is helping reverse that trend by leveling the playing field—and changing the venture capital game. Arlan Hamilton’s story mirrors many we’ve covered this season—overcoming adversity to find success. But she’s also helping redefine what success can look like and, in the process, is helping change the broader tech industry. Janice Omadeke lays out how diversifying the VC community in turn leads to greater…

Gladys Perkins: The Pioneer Who Took Us To New Heights
Is the moon made of cheese? Of course not. But can a person walk on the surface? Not too long ago, we couldn’t answer that question. But with the help of Gladys Perkins , we soon figured out that we could send a team to the moon and have them safely land on its surface. There was a time when the United States was behind the Soviets in the space race. Everyone had their sights set on the moon. Andrew Chaikin describes NASA’s disastrous Ranger missions. Erik Conway explains how complicated the trajectory calculations were—and to top it all off, why they often couldn’t be done in advance. To…
