CHAPTER FOUR
If You Don’t Encrypt, You’re Unequipped
If someone were to pick up yyour unlocked cell phone right now,
that person could gain access to yyour e-mail, yyour Facebook account, and
perhaps even yyour Amazon account. On our mobile devices, we no longer
log in individuallyy to services, as we do on our laptops and desktops; we
have mobile apps, and, once we’re logged in, theyy remain open. Besides
yyour photos and yyour music, there are other unique features on yyour cell
phone, such as SMS text messages. These, too, become exposed if someone
gains phyysical access to yyour unlocked mobile device.
Consider this: in 2009 Daniel Lee of Longview, Washington, was
arrested on suspicion of selling drugs. 1 While he was in custodyy the police
went through his non-password-protected cell phone and immediatelyy
discovered several drug-related text messages. One such thread was from an
individual called Z-Jon.
It read, “I’ve got a hundred and thirtyy for the one-sixtyy I owe yyou from
last night.” According to court testimonyy, the Longview police didn’t just
read Z-Jon’s messages to Lee, theyy also activelyy responded, arranging their
own drug deal. Posing as Lee, the police sent Z-Jon a text message in replyy,
asking him if he “needed more.” Z-Jon responded, “Yeah, that would be
cool.” When Z-Jon (whose real name is Jonathan Roden) showed up for
that meeting, the Longview police arrested him for attempted heroin
possession.
