Digital Forensics and Social Media

Privacy | Transparency

Social networks like Facebook, Twitter, Foursquare and Google Buzz can be a treasure trove for forensics investigations. The expanding ocean of data in those networks is irresistible to investigators.

Marketers are already exploiting social data to analyze associations among consumers. A startup named 33Across looks at relationships among social media users to ascertain who, for example, would be a good prospect for viewing an ad on costume jewelry. If Jane is a good prospect, then some of her friends - or maybe just people who circulate in the same social group - might be too. 33Across uses tools like tracking cookies to follow relationships.

Just as this style of data gathering and analysis can help marketing, it can help law enforcement or dispute resolution.


Digital Forensics Case Leads: New Gear, New PDFs Abuse, and Defeating TrueCrypt

Logicube releases new forensics gear, Didier Stevens discovers a new way to do interesting things with a PDF and a cooperative user, and Passware provides a means to defeat TrueCrypt.

Logicube has released two devices which look interesting. The MPFS or Massive Portable Forensic Storage provides up to 8TB of storage capacity for acquiring multiple images. The device may be attached to a forensic analyst's workstation via firewire, USB, or eSATA. The unit is compatible with Logicube's Dossier imager and Logicube's second new device, the NETConnect which as the name suggests, allows network access to forensic images. Based on the description, NETConnect is essentially a file server which enables multiple investigators to access forensic images as soon as they are acquired. The device supports Windows, Mac, and Linux and includes support for CIFS and NFS. (I've not had the opportunity to test either device but if Logicube or anyone else wants to send me a set, I will be

RSA 2010 - Digital Forensic Analyst Notebook

The RSA Security Conference was held this week in San Francisco. The conference is jammed packed with sessions, whiteboarding events, demonstrations, and more. Here are my observations and interview sound bites. I was covering RSA San Francisco 2010 as a forensic analyst and co-host of The CyberJungle, a weekly live news and talk program on security, privacy, and the law.

Digital forensics is still the non-sexy topic at RSA Security. There were no dedicated forensics tracks for this conference. But computer forensics were mentioned now and then in session talks, although many times by the audience more than the speakers.

Smart Grid Forensics
