Cyberwarfare, Hunting Threats, and Why Companies Are Breached

How do you identify online threats before they turn into disasters?Our guest Chris Nyhuis specializes in shielding clients from cyberattacks. As co-founder and CEO of Vigilant, a cybersecurity company in Cincinnati, he’s developed defenses for the food supply chain and telecom — protecting the kind of infrastructure that, when it gets hit, makes national news. Nyhuis teaches about cyberwarfare and holds multiple patents in threat analysis. And perhaps most impressive of all: The company gives 25% of their profit to organizations fighting child trafficking and supporting orphans around the world. It's built into their business model.Listen to find out what's going on in the world of cybersecurity, who's getting hit, and how to take practical steps to keep yourself and your business safer.Viligant's website: https://vigilantnow.com/FInd Chris Nyhuis on LinkedIn.

The "Blood Will Tell" Podcast

Twin brothers, 18 years old, go to a party in San Jose, California. A fight ensues. Somebody gets stabbed — and dies. The brothers are arrested, and one twin is charged with murder. The wrong twin. And he stays in jail for nearly two years before the guilty twin finally comes clean. My guest, author and journalist Jennifer Miller, met one of the brothers, Trung, while reporting a story for the Washington Post. Trung had joined a group that was performing Othello, in a program that uses Shakespeare’s plays to help rehabilitate people serving prison terms. Miller says the story Trung told her was so extraordinary that it “felt like Shakespeare himself could have written it.” She spent years getting to know the twins and earning their trust. She then shared their story in a podcast called “Blood Will Tell." It's not a true crime podcast in the strictest sense — Miller's burning question wasn't who did what. To her, this story was all about the why: Why did one brother take the blame for nearly two years? Why did the other one let him? Listen to this episode to find out how Jennifer Miller knew this was the story of a lifetime. And then, download and listen to "Blood Will Tell" to learn the answers to the deeper why questions asked above.Host: Hal Humphreys Guest: Jennifer Miller"Blood Will Tell" podcast: On Apple | On Spotify | On AudibleSponsored by: TLOxp®Music provided by Jason White, who composed our theme.Special thanks to Kim Green, who produced this episode.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *Pursuit Magazine and PI Education are part of StoryboardEMP, a media and education company in Nashville, TN.

Legislation & the PI Industry: What Investigators Need to Know

Some of the laws shaping how investigators work today were written decades before anyone had a smartphone. And right now, a new round of legislation is moving through state capitals and Congress that could change how PIs track people, pull records, and use the tools they depend on every day.My guest Edward Ajaeb is president of the National Council of Investigation and Security Services (NCISS). He watches for new laws and regulations that are relevant to our profession. And often, he's been in the room when some of it was written, making sure the PI industry has a voice at the table.If you've ever been caught off guard by a law that changed how you could do your job, don't miss this episode.

The “American Shrapnel” Podcast: Investigating a Domestic Terrorist

1996. A blast rips through Centennial Olympic Park in Atlanta. The FBI’s initial suspect — a security guard just doing his job — is cleared. The only evidence pointing to the real bomber is a grainy photo. To the FBI, he’s simply “blob man.” They have no idea who he is or how to find him.You may remember the story of the bomber who blew up the summer Olympics. You might also recall other bombings around the South in the late 1990s. You’ll most likely remember the long manhunt that followed.Our guest is Becca Andrews, the co-producer and co-host of "American Shrapnel," a podcast that digs deep into Eric Rudolph's crimes, his escape and capture, and the extremist communities that indoctrinated and sheltered him. In this episode, Andrews reflects on investigating crimes from decades ago, interviewing traumatized witnesses, and the long shadow of violent extremism. And she shares her determination to tell these kinds of stories in good faith, with respect for the real people who've lived through violence and its aftermath.

Origin Stories: The Accidental Investigator

How did a summer job at an amusement park lead to running a private investigations firm? Let’s just say the path was not direct. Molly Donaldson has one of the most interesting and varied PI origin stories around. She’s done a little bit of everything. But her story is not about indecision. It’s about experimentation. Her way of finding a professional sweet spot is to try on lots of career hats. Think of it as an investigation of herself, her talents, and her fascinations. Each job gets her closer to finding out what she does best and enjoys most. In this episode, you'll find out why finding out what you DON'T want to do is half the battle, why "What do you want to be when you grow up?" is the wrong question, and what to ask kids (or yourself) instead.Contact Molly Donaldson at her company site, Waverly Research.FInd her on LinkedIn.Host: Hal Humphreys Guest: Molly DonaldsonMusic provided by Jason White, who composed our theme.Special thanks to Kim Green, who produced this episode.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *Pursuit Magazine and PI Education are part of StoryboardEMP, a media and education company in Nashville, TN.

GenAI for Private Investigators

Today, we're talking about something that's changing the investigative landscape: Generative AI. It's everywhere, it's powerful, and it's already being used by private investigators — but not always wisely.

Threat Intelligence and Investigations

If Jennifer Mackovjak quit working tomorrow, she’d already have a fantastic investigative career under her belt. She worked as a senior detective investigator in the Manhattan DA’s office, before becoming a private investigator. She worked at Kroll, then became a senior VP for investigations at a big risk management firm. And over the years, she’s investigated wrongful convictions for the Innocence Project and Northwestern University’s Center for Wrongful Convictions. In 2020, she co-founded 221B Partners, a private investigations and intelligence firm in Chicago. 221B handles pretty high-level work: litigation consulting, fraud investigations, business and public affairs intel, and threat intelligence. In this episode, we'll talk about Mackovjak's career trajectory and find out what threat intelligence and investigations are all about.Host: Hal Humphreys Guest: Jennifer MackovjakMusic provided by Jason White, who composed our theme.Special thanks to Kim Green, who produced this episode.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *Pursuit Magazine and PI Education are part of StoryboardEMP, a media and education company in Nashville, TN.

The Beard and the Dome Talk Crime Fiction, Podcasts, TV, and Movies

After a long hiatus, Hal Humphreys ("The Beard") and John Nardizzi ("The Dome") are back to catch up on PI work, wins, and losses, and to share what they love to read, watch, and listen to when they’re not uncovering malfeasance or defending clients. Most of these books, shows, movies, and podcasts are related to crime and investigations. Some only marginally so. Basically, it's stuff they enjoy — as investigators and writers who love a good yarn. We'll publish their full list and some bonus recommendations in Pursuit Magazine next week — keep an eye out for that.
