It's been a busy time in digital forensics and incident response (DFIR). Every summer, for over 20 years, infosec and forensicators and old school hackers have gathered in Las Vegas. A mixture of very deep tech talks, trainings, and technology oriented distractions "flood the zone" in Las Vegas. Close to 15-20,000 people were in Las Vegas this summer for what has now evolved into three separate conferences, all in the same week.
July 27th was the start of Black Hat atCaesars Palace in Las Vegas. The conference kicks off with training in the last weekend of the month, and finishes onWednesday, July 31st and Thursday, August 1st, with lectures and technical demonstrations, called "Black Hat Briefings." This year, in the wake of the NSA/Snowden rowe, NSA Director, General Keith Alexander gave the opening keynote. Black Hat was more corporate than ever, with more sponsor banners, and sponsor-generated talks (disclosed by the organizers, and placed in a separate area, bravo!)
A key component of any investigation is the type of data exfiltrated. If sensitive data is on a compromised machine, risk is increased significantly. Also, there is a patch work of legislation covering various types of data which is considered sensitive (http://www.reyrey.com/regulations/). In general, social security and credit card numbers are at the top of the concern list. Since many states have encryption exemptions, a forensicator needs to know, does any media storage in the case have sensitive data in the clear?
Data can be encrypted by system administrators/DBAs or by attackers. Attackers usually encrypt data as part of the staging process prior to data exfiltation. Attackers commonly password protected and compressed the data as a .rar file. With strong passwords (32+ character pass-phrases) .rar files can be difficult to almost impossible to open with normal computing power.

Mark this date: On March 20th 2013, the non-technical managers may finally start to understand what a digital forensics professional actually does. With the massive cyber attacks on South Korean banks, media outlets, and ISPs, the role of forensicators is put front and center. The attack(s) resulted in widespread ATM outages, online banking and mobile banking offline, and tens of thousands of PCs wiped of all their data. At minimum, non-technical decision makers should finally start to understand that cyber attackers are not targeting "someone else." The attacks in South Korea had an impact on the bottom line of many South Korean firms. Since many of the same strategies for information security and incident response are used by most westernized nations, many experts agree that the attacks in South Korea are a warning sign of what could happen in the United States. We have analytical coverage of the South Korean attacks, with stories and drill downs that go beyond the
Dear like-minded people,
I'm very proud to announce that our (CERT.at - CERT Austria) latest contribution to the malware analysis community is finally available as open beta.
It's called ProcDOT - I already gave a preview of the alpha version some months ago at SANS Forensics Summit in Prague - and it is an absolute must have tool for everyone's lab, at least in my humble opinion ;-)
It correlates Procmon logfiles and PCAPs to an interactively investigateable graph. Besides that ProcDOT is now also capable of animating the whole infection evolution based on a timeline of activities. This feature lets you even quickly find out which server or which requests were responsible that specific data/code got on the underlying system, by which process it was written, how often, who injected what, which autostart registry key was set, what happened when, and so forth ...
ProcDOT's approach of correlating Procmon logs and PCAPs to a directed animateable graph has
