For IT Pros Only

Lets be clear: this is for IT people. Not because IT people are better looking and drive cooler cars than the general populace (which is true: most IT departments look like extras from the set of The Fast and Furious), but because unless you're familiar with things like the dark blackness that grips your soul when you discover that two NICs have the same MAC address on your network - you probably aren't going to appreciate this at all.

[Podcast] Penetration Testers Sanjiv Kawa and Tom Porter

While some regard Infosec as compliance rather than security, veteran pentesters Sanjiv Kawa and Tom Porter believe otherwise. They have deep expertise working with large enterprise networks, exploit development, defensive analytics and I was lucky enough to speak with them about the fascinating world of pentesting. In our podcast interview, we learned what a pentesting engagement entails, assigning budget to risk, the importance of asset identification, and so much more. Regular speakers at Security Bsides,…

PowerShell Obfuscation: Stealth Through Confusion, Part II

Let’s step back a little from the last post’s exercise in jumbling PowerShell commands. Obfuscating code as a technique to avoid detection by malware and virus scanners (or prevent reverse engineering) is nothing really new. If we go back into the historical records, there’s this (written in Perl).  What’s the big deal, then? The key change is that hackers can go malware-free by using garden variety PowerShell in practically all phases of an attack. And…

3 Tips to Monitor and Secure Exchange Online

Even if you don’t have your sights on the highest office in the country, keeping a tight leash on your emails is now more important than ever. Email is commonly targeted by hackers as a method of entry into organizations. No matter if your email is hosted by a 3rd party or managed internally, it is imperative to monitor and secure those systems. Microsoft Exchange Online – part of Microsoft’s Office365 cloud offering – is…

PowerShell Obfuscation: Stealth Through Confusion, Part I

To get into the spirit of this post, you should probably skim through the first few slides of this presentation by Daniel Bohannon and Le Holmes given at Black Hat 2017. Who would have thunk that making PowerShell commands look unreadable would require a triple-digit slide deck? We know PowerShell is the go to-tool for post-exploitation, allowing attackers to live off the land and prosper. Check out our pen testing Active Directory series for more…

More NSA Goodness: Shadow Brokers Release UNITEDRAKE

Looking for some good data security news after the devastating Equifax breach? You won’t find it in this post, although this proposed federal breach notification law could count as a teeny ray of light. Anyway, you may recall the Shadow Brokers, which is the group that hacked the NSA servers, and published a vulnerability in Windows that made WannaCry ransomware so deadly. Those very same Shadow Brokers have a new product announcement that also appears…

My Big Fat Data Breach Cost Post, Part I

Data breach costs are very expensive. No, wait they’re not. Over 60% of companies go bankrupt after a data breach! But probably not. What about reputational harm to a company? It could be over-hyped but after Equifax, it could also be significant. And aren’t credit card fraud costs for consumers a serious matter? Maybe not! Is this post starting to sound confusing? When I was tasked with looking into data breach costs, I was already familiar with the…

The Equifax Breach and Protecting Your Online Data

As we all know by now, the Equifax breach exposed the credit reports of over a 140 million Americans. What are in these reports? They include the credit histories of consumers along with their social security numbers. That makes this breach particularly painful. The breach has also raised the profile of the somewhat mysterious big three national credit reporting agencies or NCRAs — Experian and TransUnion are the other two. Lenders use NCRAs to help…

[Podcast] When Hackers Behave Like Ghosts

We’re a month away from Halloween, but when a police detective aptly described a hotel hacker as a ghost, I thought it was a really clever analogy! It’s hard to recreate and retrace an attacker’s steps when there are no fingerprints or evidence of forced entry. Let’s start with your boarding pass. Before you toss it, make sure you shred it, especially the barcode. It can reveal your frequent flyer number, your name, and other…
