Free Phone Calls From Your Computer Using Google Voice + Gizmo5

March 23rd, 2009 jdhalbert No comments

Self protection value AND it’s free?! What now?!

Now, this isn’t exactly a secret to Google Voice users, but it’s something that you might not think of right off the bat.

The following can be an invaluable tool for anything from productivity to maintaining your personal safety. Constantly having the capability to make phone calls wherever you are is an extremely important concept in personal security.

Please keep in mind, however, that Google Voice does not allow 911 access, so it’s also a very good idea to keep the local numbers for authorities in your contacts. (Mmm, I smell another article topic =p )

Think about it: you can now have a FREE (yes, it’s absolutely, completely, and in all other ways, FREE) internet phone wherever you have internet access within the United States. This can be of use if your particular location does not have good cell phone reception, or simply if you want to use your existing internet connection (or your neighbor’s, hehe) instead of a landline or cell phone minutes that you have to pay for.

Do it like this.

  1. Get Google Voice (it’ll be public soon enough if you don’t already have an account).
  2. Sign up for Gizmo5.
  3. Follow this Google tutorial.

Basically, you now have the equivalent of SkypeIn (which costs money), SkypeOut (which costs money) as well as additional features that not even Skype has–such as the ability to make calls right from the browser.

That means that you can make calls from anybody’s computer! Even public computers!

Explore the possibilities for yourself, I think you’ll be pleasantly surprised.

Also, let me offer my apologies for being so in love with Google Voice. Deal with it. It’s worth it. Trust me.

Until next time, my motivated ass offers you your complimentary OORAH! Free of charge. Take it home with you.

Don’t Engage in High-Risk Activities

Perhaps a more appropriate quote for yesterday would have been another by Voltaire: “Common sense is not so common.”

Lets face it, people do stupid things on a daily basis, and sometimes it costs them their lives. (Darwin Awards, anybody?)

Examples:

  • Illuminating your car’s gasoline tank with a Zippo
  • Flipping off gang-bangers
  • Looking down the barrel of a gun
  • Looking down the barrel of a loaded gun
  • Looking down the barrel of a loaded gun and then pulling the trigger
  • Standing on a rooftop and yelling “watch this!”
  • Practicing knife-fighting with your friends
  • Practicing gun-fighting with your friends
  • Crossing an intersection diagonally with or without a vehicle
  • Planning a summer getaway to Somalia
  • Planning a summer getaway to Somalia on your yacht

There are many more examples, but past a certain point, I’m afraid I’m giving out more ideas than anything else.

Seriously, though, think about what’s generally a dangerous thing to do, and then consider whether or not you really need to do whatever it is.

More specifics to come about this later… I’m too snarky today to write anything of value. (Can you tell?)

A Follow-Up to Google Voice

March 18th, 2009 jdhalbert No comments

I recently posted a link to Google Voice on my blog.

Upon reading about it further, it seems as though there are a number of people concerned with the privacy implications of using the service.

I, for one, will continue to use the service (due to its sheer usefulness) until it becomes abundantly clear to me that I am causing some sort of harm to myself by doing so.

However, consider this article from a computerworld.com blog: Google Voice: Press “1″ to invade your privacy.

I read that article, followed by Google’s official privacy statement concerning Google Voice.

However, it is important to realize how a Google Voice number can also protect your privacy as well, believe it or not.

Google itself will have greater access to more of your information, of course (call logs, SMSs, etc.) but for the most part (and hopefully the whole part) this will be limited to machines and computers mining for data rather than humans actually looking at it.

On the other hand, the people who call your Google Voice number will be put through additional layers of security–layers that are more likely to protect you than anything else. Google Voice numbers give you the ability to screen calls prior to picking them up, and even to block unwanted callers completely. This functionality, along with the simple fact that your real phone number is never revealed, balances out the potential risk of losing some privacy to Google.

It’s a give-and-take thing. Once it becomes open to the public, each person will have to decide for themselves whether or not it’s a tradeoff they want to make.

My recommendation: DO IT.

Google Voice: Endless Possibilities

I’ll discuss potential uses for this type of service as related to personal security later, but for now, it’s just too cool not to post.

You Don’t Have to be a Conspiracy Theorist (or Jack Bauer) to Want an Untraceable Cell Phone

March 8th, 2009 jdhalbert No comments

If you’re lazy and don’t want to read it all, here’s the rundown:

  1. Buy a used GSM phone from a private seller WITHOUT an activated SIM card and WITHOUT GPS. (Recommendation: Nokia 1600)
  2. Buy a pre-paid SIM card for a carrier that does not require personal information. Buy it from a private seller if it must be shipped to you. If you buy it in person, pay cash–this will eliminate any possible ties back to you through the credit card receipt. (Recommendation: Net10’s lowest cost card available)
  3. Activate the SIM card using a pay phone or other anonymous phone (again, to eliminate any potential ties to you). If using Net10, you should not have to provide personal information. If your specific carrier requires personal information, choose another carrier. Providing false information can be illegal and I do not in any way suggest or endorse the idea.
  4. Use the phone as infrequently as possible, and only for calls which you think are of confidential nature. Dial *67XXXXXXXXXX (X’s indicated the desired destination number) to mask your number from the caller ID of the recipient–this will help to keep the fact that this number belongs to you a secret.
  5. When you run out of minutes or time on your pre-paid card, do not renew it. Throw it away and buy a brand new card with a brand new number. Not keeping any one number for very long keeps potential eavesdroppers from catching up to you.
  6. Do not give away your phone number. Use the phone for outgoing calls only.

Now for the meat and potatoes; well you’re reading it, aren’t you?

I’m not a conspiracy theorist, I promise. If you are…. well, first of all, God help you; secondly, you might still find this post interesting, but I wouldn’t bookmark me–you are probably better suited fulfilling your secret-agent fantasies elsewhere.

First off, I feel the need to explain myself for writing this. I know you’re saying to yourself, “I’m a practical person reading a blog meant for practical people, and some guy is trying to tell me I need an untraceable cell phone?!” Crazy sounding, I understand, but practical nonetheless.

Eavesdroppers don’t have to have targets.

Cell phones have weaknesses. They can be easy to trace, locate, and even tap/bug/intercept given that there is someone out there with the desire to do so. To borrow a military term, “high value targets” for this can include the likes of corporate executives, government officials, and so on. And, even if you don’t think that you are likely to be an intended target, there is still the possibility of becoming an unintended or chance victim, possibly leading to identity theft or worse.

My phone is military-spec, it’s not weak!

Your phone may be able to withstand a bullet or a ten foot drop, but this is the 21st century–weakness more often refers to holes in firewalls and 8-bit encryption more often than it does to lack of physical durability or strength. There are numerous ways for your phone to become compromised or for it to compromise you:

The most dangerous element of cell phone insecurity is the fact that many carriers and their associated phones do not encrypt voice signals or data transfer, leaving them open to close-range hackers. Listening to a cell phone signal is illegal, but not difficult with the right equipment. Before cell phones were prominent, the frequencies that they utilize were not federally restricted and it was perfectly legal for the public to tune in to these frequencies. Today, widely available radio frequency scanners have been manufactured in such a way that monitoring certain signals (from cell phones, cordless phones, etc) is not possible. This means that all a hacker needs to do is find himself a frequency scanner from the pre-cell phone era, and he can just as easily listen to you on your cell phone just as easily as he can the local fire department.

“For goodness sakes, Jim, make a decision!”

You are going to need to make a choice. Only GSM phones are unencrypted. (T-Mobile, AT&T (Cingular), and basically any phone with a “SIM card” are GSM-based.) CDMA phones (Sprint, Verizon, etc.), on the other hand, change channels so often and in such a way that makes them virtually impossible to listen-in to continuously. Sometimes carriers even offer additional levels of encryption sometimes referred to as “voice privacy.”

Sounds simple, right? Just trash your T-Mobile and go get a Sprint phone. SLOW DOWN, cowboy. Yes, CDMA phones are more secure in this way, but you can also sacrifice a lot of security with a CDMA phone. Read on.

Having a truly untraceable cell phone does, of course, require that your service provider be completely ignorant as to your identity. This means that you must not enter a contract (unless you yourself are an identity thief) as this would associate your name, address, credit card number, etc. with your phone number. Do this, and you lose anonymity, which is a paramount concept to an untraceable cell phone.

The solution, you must narrow down your options to pre-paid service providers.

Remember the choice I told you that you were going to have to make? Well, here it is: with a regular CDMA phone, you will have voice privacy in your immediate area. CDMA phones will prevent your neighbors or close-followers from hearing your calls and intercepting your text messages and any other data transfers. All you need for this is a regular run-of-the-mill cell phone from a CDMA carrier. The drawbacks? The phone number is associated with your name. Authorities can listen to your calls with a warrant (hopefully this is not of concern for you), information related to call history and cell phone usage can be subpoenaed, and you will generally leave a trail with use of the phone.

If you value secrecy of contacts, protection from overzealous ex-’s, or whatever (again, I’m not judging) and in my opinion, a more “untraceable” cell phone, then a (fairly specific) pre-paid GSM phone is what you need.

But, if you want to be as secure as possible, we must be specific:

Most of today’s phones are GPS-enabled and vulnerable to pinging (carrier sending out a signal that prompts your phone to return it’s coordinates to the carrier). Get a phone without GPS.

  • My recommendation: Nokia 1600 (This phone tends to be cheap as well, so if you are so inclined as to pull a Jason Bourne and throw the phone in a public trash can instead of hanging up, you are welcome to.)

Your carrier will need to be okay with providing service sans personal identification.

  • My recommendation: Net10

Don’t ever let your phone number become known.

  • Take note that the *67 trick works nicely against civilian caller IDs. Don’t expect it to keep your number secret in all situations.

Alternate solutions to an untraceable cell phone:

  • Get a secure cell phone.
  • Live in a cave.
  • Don’t call people.
  • Come to the realization that you really probably don’t need one. (But it’s still fun!)
  • Be a teenage girl and prompt your eavesdropper to commit suicide by never shutting up (sorry, teenage girls, nothing personal). But seriously. This is probably the most effective way. Stay tuned for an article about being a teenage girl.

Criminals are SO last year! Like O-M-G, totally!! (Sorry, I got carried away.)

I take no responsibility for misuse of this information. The intention of this blog is to assist people in self-protection. Unfortunately, overlap between self-protection and criminal activity do exist. If you are plotting nefarious activities, have fun going to jail–the police are smarter than you. Do not ask me how to commit crimes. I will fuck you up.
