#OpNasaDrones Hack – Daily Security Byte EP. 210

A hacking group calling themselves AnonSec claims to have hacked NASA’s network, and shared a 250GB dump of NASA drone data to back up the claim. Meanwhile, NASA says the data is public, and claims they can’t find evidence of a breach. Whether or not AnonSec’s story is fiction, I think you can learn from it.

Vtech Update Proves SQLi – Daily Security Byte EP. 184


On Monday, I highlighted the Vtech breach. A hacker was able to steal millions of records from an online kid’s toy manufacturer, which including information about children. Over the past day, we’ve learned two new updates about this story. One increases the scope of the breach, and the other explains how it happened (Spoiler: my hunch was correct). Watch today’s for these updates, and to learn how to protect your web site from the flaw that allowed this attack.

Vtech Leaks Kids Data – Daily Security Byte EP. 182

What’s worse than the average data breach? A breach that involves our childrens’ private information!

In Monday’s episode, I talk about how a “greyhat” hacker stole over 190GBs of data from a company that makes an Internet-connected kid’s toy. Luckily, he doesn’t seem to plan on using the data with malicious intent. Nonetheless, it’s still an eye-opening hack. Watch the vlog to learn more about this attack, and why we all need to think about what types of data we share online.

Visibility: The Missing Layer of Information Security

No one wants an attacker or malware in their systems. That’s why the information security community spends so much time and effort on prevention. We try our best to implement defenses that stop today’s threats, while imagining new safeguards to catch future ones.

The problem is, complete prevention is simply an infeasible goal. We’re all human. No matter their competence, engineers will occasionally make mistakes that expose new vulnerabilities. Furthermore, even if we had that unattainable “perfect security system,” users would still mess up and introduce new threats. Meanwhile, crafty hackers continue to find new holes to exploit. No matter how great your defense, it’ll never be perfect.

Visibility: The Missing Layer of InfosecThat’s why visibility should play an important role in your information security strategy. Since you can’t stop every attack, you need to have mechanisms that help you detect them. That way, you may be able to respond before it’s too late.

Recently at Gartner’s ITxpo Symposium, I gave a presentation called Visibility: The Missing Layer of InformationSecurity. In this talk, I share how data breaches have increased, while at the same time, it takes us to longer to identify them. I also share a detailed timeline covering four major breaches from the headlines, and illustrate how long the attackers were in these organizations before the breach was even discovered. Next, I show how visibility tools can help you discover breaches more quickly, perhaps even allowing you to mitigate them before the attackers make off with your data. Finally, I offer six things we can learn from these breaches.

If any of this sounds interesting to you, Garter has made my presentation available on-demand. Click here to learn how visibility tools, such as WatchGuard Dimension, can plug the missing gap in your information security program. — Corey Nachreiner, CISSP (@SecAdept)

Backdoors and Watering Holes – WSWiR Episode 162

Cyber security has become mainstream. Nowadays, there’s more information security (infosec) stories each week than the average IT professional can keep up with. If you find yourself falling behind, let our daily and weekly videos keep you informed. If you watch my Daily Security Bytes, you can probably skip this weekly summary. However, if you prefer to recap the week in one go, this video is for you.

This week’s episode includes surprising new updates to the Ashley Madison hack, a backdoor in a bunch of consumer routers, and a watering hole attack targeting the EFF. Watch the video below for the scoop, and check out the references section for more.

Show Note: A couple notes this episode. First, while I posted last week’s summary video to YouTube, I was not able to blog about it due to my early week travel. If you missed it, you can view it here, or just subscribe to my YouTube channel to see my videos right when they come out. 

Also, I will be traveling in Europe all week to attend WatchGuard partner conferences. I will try to post some videos, but I probably won’t get to one every day, and will post them at unusual times.
