Telemarketers Aim to Scam via Social Engineering



Most people have experienced robocalls and telemarketers looking to sell them something. While such calls are annoying, up until recently, they were just annoying. Very few people actually bought the products being sold, but they sold enough to make robocalls economically feasible. Most recently, however, the robocallers have taken a new strategy: known as the "can you hear me" scam. David Lazarus, in his latest L.A. Times article, discusses the popular new telemarketer scam and what you can do to protect yourself from it.

Just as technology is constantly improving to make overall quality of life go up, that same technology can be used to make life more difficult for some. Technology similar to that used by Apple's Siri and Google's Alexa is now being used by computer programmers to make telemarketing calls by a computer seem conversational enough that the recipient doesn't hang up immediately. Because the technology is not perfect yet, the target will quickly catch on and realize that they're speaking to a computer, but in the first few seconds, they may say something that can be used against them.

The "can you hear me" scam is a feat of human engineering, where telemarketing companies demonstrate a thorough understanding of the dynamics of true human conversations. By using that knowledge, the computer is able to get a response they want, in order to scam the responder later. In this scam, the computer asks "can you hear me" with the same inflections as a human, which can usually cause the recipient of the call to respond "yes." Giving an affirmative response is the worst thing you can do in that situation, according to police officials.

When the recipient of the call says "yes," the computer already has what it needs to move forward with the scam. The affirmative response can easily be edited later to make it seem like the target was giving the company approval for a purchase of some kind. There have been several situations over the past months where people have responded to the question "can you hear me" and later found that their credit card had been charged for products they never ordered. A safe rule of thumb when dealing with telemarketers, especially those employing these tactics, seems to be to hang up immediately. If you're not sure if someone is a telemarketer or not, avoid affirmative responses and ask a lot of questions to determine if the answers seem like they are coming from a computer. Machine learning and artificial intelligence are just starting to boom, so be on the lookout for similar scams in the near future.

Bitcoin's True Founder - Revealed at Last?



Bitcoins are a form of electronic currency first introduced to the public in 2009 by a creator who goes by the pseudonym Satoshi Nakamoto. The "mining" of these Bitcoins is performed by computer software following a mathematical proof. The software is open-sourced, which means anyone can use it and check it out to see how it works. Recently, as discussed in Samantha Masunaga's L.A. Times article, an Australian businessman and computer scientist named Craig Wright came out of the shadows and provided evidence showing that he may, in fact, be the elusive Mr. Nakamoto.

Bitcoin's protocols make it impossible to churn out an endless supply of Bitcoins; only 21 million coins can ever be produced by "miners." That's one of the things that sets the electronic currency apart from more "traditional" currencies. With dollars or Euros or any other form of government-backed currency, an unlimited number of bills and coins could theoretically be printed. Sometimes it is done to provide a shock to try to start a stagnant economy, but, more often than not, it results in massive inflation and more economic downturn than before. There is a limit on the number of Bitcoins in the world, which means their value is pretty stable, and inflation doesn't really exist.

Additionally, while central banks can charge exorbitant fees to someone trying to open up an account or someone trying to send funds internationally, Bitcoin cuts out many of those fees. A Bitcoin account can be created in a matter of seconds, with no fees. The decentralization of Bitcoin's network means that there is no bank to default on any loans, so you know your "funds" are safe. Best of all, the network is extremely transparent since every transaction is recorded in a secure "blockchain" that can be added to, but never changed. Unfortunately, most normal retailers don't accept Bitcoin as a form of payment. Over recent years, however, Bitcoin has become much more prevalent, especially with online retailers, so it is expected to come into more widespread use.

Although Wright, an entrepreneur with several masters' degrees and a couple of doctorates, came out with some proof showing that he may be the true creator of Bitcoin, there are still many doubters. In his digital messages claiming to be "Satoshi Nakamoto," he signed off using certain cryptographic keys that could be found in Nakamoto's work in the early days of Bitcoin. He also published a very technical post on his blog with information that no one but Bitcoin's true creator should have. Wright claims that he has chosen now to reveal his identity because he is tired of the misinformation being spread about Bitcoin and its stability. Additionally, the media has long suspected Wright's alter-ego, and he wanted to put an end to the investigations into him and his family. While he hasn't provided undeniable proof, it seems very likely that Satoshi Nakamoto's secret identity has finally been revealed to the world.
