"You have to be fast when seizing a mobile handheld device in the wake of a security breach – a dead battery or still-live signal could wipe out or taint the evidence stored on it.
"As handheld devices gain more data features and storage, they also are increasingly becoming a smoking gun in an enterprise data breach, especially when it comes to the insider threat, security experts say. But getting hold of these devices and freezing the evidence on them isn't so easy.
"The biggest data breach [with handhelds] today is probably lost or stolen handhelds," says Randy Abrams, director of technical education at Eset. "The fact that many of these devices support MicroSD card of at least 2 gigabytes of capacity makes them extremely agile for transporting data. Insiders have no problem copying large amounts of data from a PC to their smartphone. Even if the possession of the data is legitimate, a lost device with unencrypted data can be a gold mine for the finder."
But the evidence on the devices can be easily lost or tainted. Amber Schroader, president and founder of Paraben, says the key is to maintain power on the device and protect it from any changes that could contaminate the evidence on it. "You can put aluminum foil around it to make sure the signal is blocked" or put a Faraday cage around it to protect the evidence, she said during a presentation at the recent CSI 2008 conference.
The first responder to a handheld device could have less than a minute to properly seize and contain one of these "volatile" devices, she says. (((Sort of like netting butterflies. Except with people's personal lives inside.))) If the battery dies, so does the forensics data that was on a Windows Mobile device, for instance, Schroader said. "Every three days a new digital device goes into the consumer market," she said, and there aren't enough forensic examiners to keep up with them.
Schroader noted that in many cases today, investigators are conducting full forensics analysis in the field and don't have the luxury of sending the device off to a lab. "They're doing more live-on-the-scene instead of processing it in the lab, which can take over nine months with an analysis," she said. Instead, you can process and grab evidence off of a handheld right then and there, she said.
"The biggest IP [intellectual property] leaks are in...my pocket," she said. (((I idly wonder whose pocket has the WORLD'S BIGGEST IP leak. Bin Laden's pocket, maybe?))) And with 2-GB SIM cards arriving next year, one of these devices could store an entire customer list that could be lost, stolen, or sold, for instance.
Aside from locking down the handheld by maintaining a power supply and cutting off its wireless signal, investigators also should seize any accessories to the device that could contain evidence, Schroader said. That includes synch stations, cases, SIM and media cards, and headsets....
