In the mid nineties, I was the world's most wanted hacker for hacking into 40 major corporations just for the challenge. I'm now an author and security consultant to Fortune 500 and governments worldwide, performing penetration testing services for the world’s largest companies. I am also the Chief Hacking Officer for KnowBe4, a company that develops software to train employees to make smarter security decisions. Ask me anything.

Ok, it's time for me go. Thank you very much for participating in my first AMA. A final answer is to what I've been up to recently besides hacking and speaking. My 4th book, The Art of Invisibility, was released 2 days ago. This book is targeted to the everyday person that wants to protect their privacy or even get off the grid entirely. It's too bad the "fugitives" on Hunted didn't get a chance to read this first. In addition I've very excited to be involved with growing KnowBe4 to over 200 employees in the past 4.5 years. It's our job is to stop the former Kevin Mitnicks of the world. It's too bad John Podesta didn't take the training as he might not have clicked on that email.

My speaking schedule is posted on my website, stop by and I'll get you one of my famous business card for free.

Kevin! Just completed some of your training from KnowBe4 for work. I have my completion certificate hanging on my wall. But could we maybe get it in a font that's not comic sans?

KevinMitnickOfficial2122 karma

Ha! I'll tell you what, get your certificate over to KnowBe4 with a copy of this thread and I'll make sure that I sign it personally.

ReV-Whack1188 karma

I just want to thank you for your business card. Sadly I locked myself out of my house one day and had to take it apart in order to use the picks to break in.

In short you helped me break into a house and got me laid.

Where can I get more of your cards?

KevinMitnickOfficial1148 karma

Wow! I better raise the price of my cards!

DevilsAdvocate1217818 karma

How hard do you laugh during movies when two hackers are locked digital combat, typing at 1,000mph?

KevinMitnickOfficial1990 karma

I pretty much just role my eyes and chalk it up to non-technically astute writes. However Mr. Robot has changed that and are getting things spot on.

BTW, I do type at 1,000mph, 1,024 to be exact.

theHonkiforium595 karma

Keep working at it and you may eventually get up to 2600.

KevinMitnickOfficial382 karma

Well said

terryleopard764 karma

Can you use visual basic to create a GUI Interface to track the killers IP?

KevinMitnickOfficial1084 karma

No need, it's already been done.

Fun fact, when I had my role on the show Alias I was still on probation and not allowed to use a computer. For my scene with a computer I had a prop computer with a monitor that was being operated remotely to follow my actions.

Sumidiotdude753 karma

can you hack my wife's texts so i can find out if she's cheating on me with brett?

KevinMitnickOfficial2206 karma

Brett already paid me to keep quiet

williseeyoutonight598 karma

What was the most sensitive/surprising information you found out?

KevinMitnickOfficial940 karma

That a federal judge in northern California had an intercept on his line. I would check to see if any of my friends had a tap on their lines and stumbled upon the fact that a judge had one on his line.

MakeAutomata312 karma


KevinMitnickOfficial634 karma

No, I wasn't interested. My goal was to determine that my communications were secure for self preservation.

TheRedChair21503 karma

I know nothing about hacking. Just out of curiosity, if someone really pissed you off with a question here, could you hack them? Is that how it works? Do you need a certain level of ability or could anyone do it with a YouTube tutorial?

If the answer is yes please don't demonstrate on me! Thanks for the AMA!

Edit: Aw, downvoted... hope I didn't seem rude...

Edit: Aw, upvoted! Glad I didn't seem rude!

KevinMitnickOfficial346 karma

Let's take this offline, I'll email you later ;)

simplyshpadoinkle436 karma

On a scale of 1-10, how paranoid are you on a regular basis?

KevinMitnickOfficial784 karma

I wouldn't call it paranoid, skeptical is a better word. It depends on the situation. Let's go with a 6.

ChuckEye356 karma

What was the most memorable or impressive item of the "FREE KEVIN" campaign that you recall seeing?

KevinMitnickOfficial846 karma

While I was in a Federal Detention Center in LA I could look out the very small window and was able to see an airplane with a "FREE KEVIN" banner flying around.

Drunken_Economist310 karma

Hi Kevin, big fan!

If you had never been exposed to computers when you were younger, what direction do you think your life would have taken? What would be your job today?

KevinMitnickOfficial367 karma

I would probably be competing against David Copperfield as a magician because I love magic.

hf_rainman258 karma

What are your thoughts on Ed Snowdan?

KevinMitnickOfficial1077 karma

My position is that Ed is a whistle blower, not a traitor. I was happy when he revealed that the US government was breaking the law by spying on our citizens. That was an illegal activity and needed to be revealed.

It's my position that Ed shouldn't have revealed our operations related to the monitoring of foreign entities, that's what the NSA is expected to as part of their mission, just like foreign entities do with us. That's the spy game.

cubatista92239 karma

What would you say to teens that are into hacking? Are the consequences now worse than when you were phreaking? What projects should they channel their energy to?

KevinMitnickOfficial594 karma

Don't follow in my footsteps. Become good at offense using virtual machines and the various toolsets that are available. Learn about development and network administration to get your fundamentals before going directly into security.

The consequences are certainly more severe, and likely will only get worse. This is because of rise in publicity of hacking with public events such as the Russian hacking during the recently election and news around Edward Snowden. What your seeing in the making is a "War on Hacking" to replace the "War on Drugs".

10speed705235 karma

Hey Kevin, big fan. What do you think your biggest accomplishment is both legal and illegal? Also, Did you have any thoughts of harming anyone (including yourself) when the FBI was coming?

KevinMitnickOfficial549 karma

My biggest accomplishment was turning my life around, lemons to lemon-aide. I'm able to take all my skills and use them to improve security. I'm extremely fortunate that I've been able to take this "mischievous" behavior and use this to help businesses to protect themselves from the other Kevin Mitnicks that are out there. Look at it this way, it's like Pablo Escobar becoming a successful pharmacist.

Edit, to answer your last question, I never thought about harming myself. I did think about trying to escape but I didn't want to end up getting shot, that would go directly against my general desire not to harm myself or others.

FonziusMaximus219 karma

Kevin, for people thinking of getting into the security industry, what particular skills do you see being the most valuable now, and the most valuable in 10 years? In other words, of which types of current emerging tracks or concepts will tomorrow's infosec managers be skilled practitioners?

KevinMitnickOfficial344 karma

Right now: It depends on what area of security, for me I'm always looking to hire expert pen testers. I look for people with skill sets in physical/technical/wireless areas.

What's hard to find today are those that have the skills to find find bugs in web apps.

10 years? I need my crystal ball because I have no fucking idea. I would say that one needs to constantly and vigilantly keep up to date with what is going on on both sides of the fence. It's a matter of keeping aware of the landscape as it evolves. 10 years in this industry is 100 years in any other industry. What did we have to watch for 10 years ago?

spillitout123183 karma

Hey Kevin, thanks for the AMA. What motivated you to go into Hacking and what tools did you start with?

KevinMitnickOfficial338 karma

What motivated me to get into hacking was because I was involved in phone phreaking and used to pull pranks on my friends. I wanted more control of the systems involved and one thing led to another. My first tool was a telephone, after that was a VT100 terminal and a Hayes 300 baud modem. Remember I started in 1978.

cmyersavi170 karma

Do you have kids? If so, do they realize they will never be able to pull anything secretive past their father?

KevinMitnickOfficial279 karma

I don't have kids yet but I believe they'll be the best social engineers in the world. They'll get good practice on their parents.

OscarWilde1854169 karma

Could you start a nuclear war just by whistling into a payphone?

KevinMitnickOfficial311 karma

I can not confirm or deny

wannatryanother100 karma

Hi Kevin, Do you think the rise of crypto currency (Bitcoins, etc.) will have a net positive or negative effect on society?

KevinMitnickOfficial118 karma

I think it's a positive effect, it gives the public another way to pay for products and services somewhat anonymously. It's just another tool that can be used by society in a positive manner.

HelloThinkpad96 karma

Hello Kevin, Big fan, Have read you book tons of times. I am also a fellow ham radio operator and living in North Carolina. After reading your book I had some questions.

When was the last time you ever messed around with radios and police scanners? This is one of my current hobby's.

Also, to me one of the most interesting people in your book was Jonathan "JSZ". Have you ever talked to him since 1995?

After reading you book and reading about you editing the firmware and disabling registration in the Motorola MicroTac Ultra lite , I also have always wondered how knowledgeable you are in programming languages such as C and other languages.

Hope their is sometime in the future I can meet you in NC.

KevinMitnickOfficial85 karma

Nice to meet you as well. I haven't messed around with police scanners since the 90s. I do occasional ham radio.

I've spoke Jonathan very few times, he had really distanced himself from me due to the prior history with the Shimomura hack. Now that the statue of limitations has run he has nothing to worry about.

Regarding languages, my first programming was at 21st Century Fox as a COBOL programmer. I'm familiar with many languages but modifying the existing assembly was how I did the work on the Motorola.

I look forward to meeting at some point, I don't have anything scheduled in NC at the moment. Check my website as I keep my speaking schedule there. Mitnick Security

HelloThinkpad15 karma

How did you meet JSZ on IRC? , Also on your laptops were you running MS-DOS?

KevinMitnickOfficial26 karma

I believe I was introduced via friend, we did communicate via IRC and telephone. At that time we were running MS-DOS, primarily to use comms programs and store data.

keeegan80 karma

What is your favorite tool? What tool blew your mind the first time you saw it?

KevinMitnickOfficial155 karma

Burp Proxy Pro is really a great tool. XKeyscore is what blew my mind the most. Back in the 90s it was direct access to the DMV in CA.

Vrael_Vrangr74 karma

Hey there Kevin, What is one area of security/hacking that you would like to improve at? What is your favorite story in hacking history that you were not a part of?

KevinMitnickOfficial110 karma

In the security and IT field there are so many things that are changing on a daily basis so you can't be good at everything. Right now there is a big need for people with the ability to find exploits in web apps.

An interesting bit of data is that when my company does engagements I still involve myself because I really enjoy the hacking process.

I have many favorite stories but I really enjoyed Kevin Poulsen's attack on Pacific Bell. I was very impressed by his bravado and how he would physically go into facilities. I would have liked to have met him earlier on in my hacking career when I was hacking the phone companies as that was my true love back in the 90s.

greymattr72 karma

How accurate was the book/movie takedown ?

KevinMitnickOfficial176 karma

I would say the book was 90% false and defamatory, the movie was 99%. The good news is that Jeff Estin, creator of White Collar, is doing the script for Ghost in the Wires. I hope that the script is picked up and it turns into something picked up by a production company.

cmeilleur133772 karma

Hey Kevin. Big fan of your books, and you in general. I was wondering if you still have those nifty business cards, and how hard it would be to get one in Canada?

KevinMitnickOfficial85 karma

Thanks man. I do still have those cards and Canada shouldn't be a problem, you can get them from my website if you like, or catch me at a show.

Reedit_girl31 karma

How come you don't have an online store? Why do you only take cash?

KevinMitnickOfficial70 karma

Seriously,because then I don't have to deal with fraud.

I actually prefer to give them out for free in person but I have them for sale if someone can't make it out to see me.

hf_rainman62 karma

Back in the day, when you were wanted, the tech was different, you did't have tools like Metasploit, Armitage, etc. Was it easier or harder to break into stuff? And also how long did it take you to adapt to the "new ways of hacking" after getting out and serving probation? Or did you need time to adapt? And, also, it this day and age it's unimaginable to be AFK for even a day let alone for the time you were, so how was it? Big fan! Keep whistling those launch codes!

KevinMitnickOfficial92 karma

I would say it's the same. Systems were less secure but to compromise them you had to write your own exploits. An effective method was social engineering the operators of the systems, a tactic that is still very successful today. That part works the same today as it did yesterday.

While I was in custody I continued to read and follow what was happening in the wild. I couldn't use a computer for 3 years so there was some catch up to do but I wasn't completely in the dark about what had been going on. People sent me books on HTML and whatnot while I had no access to computers.

Xanola59 karma

Oh are you the one they call 4Chan? Such a good hacker. In all seriousness, anything us average computer users should be doing/avoiding that may not be common knowledge?

Finally, what did you think of the show Mr. Robot?

KevinMitnickOfficial106 karma

I'm not actually 4Chan, sorry to break that news.

Not common knowledge? Use 2 factor authentication, use a password manager, use VPN when on public WiFi, and be aware of phishing attacks. Phishing is likely the number one way someone would be able to get you.

Regarding Mr. Robot, I love it. I've had the pleasure of meeting several of the people involved with that production.

Guairdean50 karma

Do you still have business cards that are lock pick sets?

KevinMitnickOfficial66 karma

Yes, I don't think I could have any others at this time.

ageekatwork46 karma

Hi Kevin, do you think overall computer security is getting better as we devise way's to make things more secure, or is the growing number of tech illiterate people, or even techie people who just can't be bothered to keep to good security practices off setting the gains we are making?

KevinMitnickOfficial49 karma

It's really hard to find skilled security people, we really need to help develop people's skills in security testing. Testing security is an important step that needs to be taken.

NoChillPhilll46 karma

What are your thoughts on Fortran program language, is it good? Is it dead? My university is insisting that I have to learn how to program in Fortran, so here am i asking this.

KevinMitnickOfficial107 karma

Funny thing you would ask, the very first program I wrote was in Fortran. It simulated the login process of my teachers computer and I used that to phish his login credentials. I never did "hello world", I got my teacher's password as my first project.

C and Python make more sense but if the university says you need it, well, you probably should learn it. But certainly don't stop there.

luxangelus38 karma

If you could go back and give yourself any advice just before you started hacking, phreaking etc, what would it be or would you?

KevinMitnickOfficial91 karma

Don't get caught and if you're using cell phone to dial in always keep moving :P

Rambles_Off_Topics37 karma

What's the most important, or foremost thought process when attacking or protecting a digital entity?

KevinMitnickOfficial77 karma

Really thinking out of the box, expecting the unexpected. Really to me, the thought process is like puzzle solving. It's much harder to protect than it is to attack, the attacker needs only to find one hole to make it in.

FearTheTooth36 karma

In your opinion, how much protection does software like Norton provide for a personal computer?

KevinMitnickOfficial67 karma

AV is a necessary evil for a personal system. That said, whenever I'm involved in ethical hacking we always work our way around AV.

KevinMitnickOfficial38 karma

It's well, thank you


What's your favorite pizza topping?

Also, thank you for being such an incredible human being.

KevinMitnickOfficial38 karma

Thai chicken pizza from CA Pizza kitchen!

hf_rainman30 karma

How often do people try to hack you?

KevinMitnickOfficial89 karma

Constantly, all the time. Since there are so many ways to compromise a target I completely reload all of my systems at least once every 6 months from a trusted source. If I was on Windows I would do it every week.

Adium26 karma

With all the news we've seen lately about security, what do you feel is under reported or over exaggerated?

KevinMitnickOfficial75 karma

I think sophistication that was behind the John Podesta phishing was highly exaggerated. This was a case of standard phishing, basic security awareness training would have prevented this. It wasn't a huge technological achievement, it was simple spear phishing.

hereticalvet23 karma

What does your playlist consist of and what is your fuel when locked in a long work session?

KevinMitnickOfficial71 karma

I don't play music while I'm working because it's distracting. When I am listening it's Def Leppard, Lynyrd Skynyrd, Eagles, AC/DC and other classic rock. And throw in some Eminem and Black Eyed Peas.

I really appreciate your compliments and in fact that book is written for the non-IT person. It was my hope that people could use it as a tool to protect their privacy.

angryKid123 karma

Why did you choose Condor as your hackername back in the day?

KevinMitnickOfficial49 karma

At the time one my favorite movies was 3 Days of the Condor. In the movie Robert Redford called up the CNA bureau to get someones number. I was impressed that the writers had included such an accurate detail.

blaatapaat22 karma

Dear mr Mitnick,

Did you stay up to date on developments concerning your field of work during your incarceration and (iirc) supervised time? And if so, how?

And following up on that question; is it getting harder to stay up to date with the current developments while getting older?

KevinMitnickOfficial50 karma

My kind supporters sent me lots of materials, including books, emails and information. At one point my watchers tried to stop this, saying that I was getting encrypted data on how to escape in the mime headers of the printed emails.

--Hello_World--22 karma

Is penetration testing as exciting as it sounds?

KevinMitnickOfficial45 karma

Yes, I love it. It has been my passion since the 70s, hacking is the ultimate game. I love playing and I love winning.

itsthateric22 karma

Recommendation on a Laptop? And what do you use and why?

KevinMitnickOfficial73 karma

I could tell you but then I would have to kill you. Are you trying to do reconnaissance on me?

I will say I like OSX and I like the aesthetics of the Apple hardware. I'll use VM for my Windows systems. I do use Linux and I typically go with Debian or Ubuntu.

rickmuscles20 karma

If you suspected your wife was cheating, how would you catch her?

KevinMitnickOfficial76 karma

What's the most immoral/questionable thing you've seen while being involved in this whole hacking thing?

KevinMitnickOfficial55 karma

The Albert Gonzalez case, you can read about it here

KingDavid7314 karma

I saw Takedown 15-ish years ago, so obviously I already know the whole story, right? :P

KevinMitnickOfficial52 karma

Yeah, not so much. Check out Ghost in the Wires for the full story.

najing_ftw13 karma

Will you get one of your hacker buddies to release Trump's tax records?

KevinMitnickOfficial19 karma

I don't have to hack, I could just ask uncle Jack.

sliverme8 karma

Do you feel that because there was slim to none as far as security we know today back in the 90s that anyone could have done that or there was actual skill involved? Is it not just another Howard Stern case of nothing special just the first hence the success..

KevinMitnickOfficial13 karma

It really depended upon the target. Some sites really did have a lot of security even back in the day. The biggest difference is the availability of toolkits, it was much harder to get/use/QA those types of things.

There was less security awareness back in the day, now there is a lot more awareness. However, that's been somewhat negated by the huge availability of tools that an 11 year old could pickup and try to use against targets.

Mutt12232 karma

What is your favorite flavor of ice cream?

Peanut butter and chocolate, Reese's
