Handling Caller ID Spoofing?

An anonymous reader writes "A nice little old lady I know has had her number spoofed by some car warranty scammers. They're calling hundreds of potential victims per day pretending to use her phone number, and the angry ones call her back; some of them have even left death threats. She's terrified. Some well-intending anti-telemarketing folks have posted her address on the 'net as well. How can we figure out where these scammer bastards are, and what's the state of the current legislation to prevent caller ID spoofing? I called the FBI in Boston (near where she lives) and they said they can't help. She's called her phone company, but they said they can't help either. She's had the same number for over 50 years and doesn't want to change it." If the Feds can't or won't handle it, what's the best approach here?

      Morally I agree with you, but realistically the legal imperative isn't there to catch those responsible, and even if they were caught it doesn't change the situation.

      The real problem is that good security was never built into telecommunications systems as they were designed by people who were used to being the only game in town. Now that's not true anymore, anyone with a PC and an internet connection can get into the game, but there's no security behind it. Telcos don't really give a crap as long as you buy their service so there's no help there, and the FBI only really care about "serious" crime so it's unlikely they are going to tackle the issue. It's a global game of hot potato that won't be solved without serious work.

I was laid off, had a mortgage, was desperate, and when you've been unhirable for almost a year, and burning down your vested stocks because some CEO got a bonus to lay you off when that bonus (several $10s of millions from what i heard) could have kept me and others employed for a few more months), your world starts to implode.

    So, i gambled (and lost) some $700 on an asshole who made a dumbass out of me. He promised (IIRC in writing as well as verbally) to return my investment if in 30 days (or so) i wanted to cancel my involvement. He dragged my ass out for weeks past that time, and then I called the FBI. I suggested this guy, one Anthony Brown (who claimed to have contacts at Cisco and ohter places, and claimed he was having meetings at times at their Milpitas location), might be doing this in an interstate manner. I was told they couldn't do anything. The local police in the Sacramento & San Joaquin areas couldn't help either. I suggested to the FBI agent that if they or law enforcement couldn't help me that I should probably find some criminals who would not take kindly to being ripped off, and that I should make an appointment with Mr. Brown (if that was even his real name and real ID), and "steer" him toward some mob or gangster types who would probably also not know Brown was a bottom-feeding piece of scum about to meet his Hell on Earth. I actually wanted BLOOD. I wanted to KILL that m'f'r, as $700 was a serious amount of money to take, STEAL, from someone whose world was already on fire. So, if he actually took their money, and then fucked THEM, he'd be sorry he ever met me or them.

    I hung up. Later, friends and family helped me out a little more, but it is a shame that vigilantism is/can be illegal.

    My advice: If your world is on fire and you get involved with anybody who is going to get money from you, get their fingerprints off a restaurant glass, a writing pin from which you can lift the prints with cello tape, or something. Make him/her sign YOUR documents that their ass is voluntarily on a hook to YOU since their exploiting your pitiful situation.
