  A Modern Scam Using Classic Phone Technology 

  

  By Greg Collier

  There was a time when dialing a few numbers on your landline could activate all kinds of convenient features. Remember *69? It was the go-to for identifying the last caller. *67 was every prankster’s friend, temporarily blocking your number from showing up on caller ID. Those star codes were an early taste of what we now take for granted with smartphones, quick shortcuts to control how our calls worked. Although landlines may have largely faded from daily use, some of these codes remain, quietly embedded into mobile networks today. But what was once a helpful feature is now being exploited in a way few would expect.

  Among the lingering * codes are *72 and **21, both still active in many cellular services. They allow users to forward calls from their phone to another number. It’s a practical function if you’re traveling or temporarily want another person to handle your calls. However, what was designed for convenience has become a tool for deception. Scammers have found ways to manipulate these codes to steal personal information and commit financial fraud, taking advantage of the trust we place in what feels familiar.

  Imagine receiving a phone call from someone posing as a representative from your bank, with just enough personal details to sound legitimate. They warn you about an urgent issue with your account and offer a quick solution: dial *72, followed by a ten-digit number, to ‘secure’ your line from suspicious activity. It sounds easy enough, and in the moment, with alarm bells ringing in your head, you might not think twice. But what actually happens when you follow those instructions?

  That simple string of numbers forwards all your incoming calls to a number controlled by the scammer. This means every call you receive, whether it’s a friend checking in or your bank calling to verify a suspicious transaction, gets rerouted. Worse still, if a scammer intercepts a call that contains a two-factor authentication code or a password reset link, they can easily access your financial accounts, email, or other sensitive platforms. The process is invisible to the victim, who only realizes too late that they’ve been locked out of their own information.

  If you find yourself in this situation, the good news is that turning off call forwarding is straightforward. On Verizon, dialing *73 disables it, while T-Mobile users can enter ##21#. But as with most scams, prevention is key. Awareness of these old * codes and how they can be abused today is essential to avoiding trouble.

  The lingering presence of these codes on modern networks serves as a reminder that even outdated technology can become a liability. Just as those old landline tricks once helped us control our phones, they now provide a pathway for modern criminals. The tools may be familiar, but the way they’re being used today is anything but.

  A cautionary tale of SIM swap scams 

  

  By Greg Collier

  The nightmare of having your entire digital existence commandeered by malicious actors is a chilling reality for one unfortunate family from the Chicago area. What began as a routine day turned into a months-long ordeal of trying to reclaim control over their smartphones and, by extension, their digital lives after falling victim to a SIM swap scam.

  SIM swapping, also known as SIM hijacking or SIM porting, is a type of cyberattack where a malicious actor fraudulently gains control of an individual’s phone number by tricking the victim’s mobile carrier into transferring the number to a SIM card under the attacker’s control. This process involves exploiting vulnerabilities in the carrier’s authentication procedures or social engineering techniques to obtain personal information about the victim, such as their account PIN or other identifying details. The term SIM swapping can be misleading because the attacker doesn’t actually require physical possession of the victim’s SIM card to carry out the attack.

  It all started when the family’s wireless account was hacked, leading to the takeover of not just one, but all five of the family’s smartphones linked to the account. Suddenly, their devices were rendered useless, stripped of cellular service, and locked out of essential apps and services.

  Unauthorized apps were installed on their phones, contact numbers were altered, and passwords to numerous accounts were changed without their consent. The financial toll was staggering, with losses totaling thousands of dollars in stolen funds from various platforms, including investment and cryptocurrency apps.

  It’s suspected that the attackers obtained access to the family’s mobile phone account either by stealing or correctly guessing the account’s PIN. Experts advise regular changes to PINs and caution against using easily guessable information, such as birthdates, as security credentials. Moreover, limiting the dissemination of personal details on social media platforms can help mitigate the risk of identity theft.

  To mitigate the risk of SIM swapping attacks, individuals can take several precautionary measures. Avoid using easily guessable or recycled passwords, and consider using a password manager to securely store and manage your credentials. Whenever possible, use authentication methods beyond SMS-based two-factor authentication (2FA), such as app-based authentication or hardware security keys.

  Again, it’s not recommended to use text messaging to receive your authorization codes. Instead, it’s recommended you use an authenticator app along with a biometric authentication such as a fingerprint scanner. This way, your 2FA information is tied to your device and not your phone number.

  Father charged with using young son in phone scam 

  

  By Greg Collier

  In a world where acts of kindness are meant to be cherished, there are those who exploit such generosity for their own selfish gains. The recent case of one alleged scammer from Florissant, Missouri, sheds light on a disturbing trend where a father allegedly used his young son as a pawn in a scheme to scam unsuspecting individuals out of their hard-earned money.

  According to the Florissant Police Department’s probable cause statement, the incidents unfolded in late August and late September. Victims recounted encounters where a young person, later identified as the scammer’s son, approached them under the guise of needing to use their phones to call his father. After seemingly innocuous interactions, victims later discovered unauthorized transactions in their PayPal, CashApp, or Venmo accounts, with funds transferred to the scammers online payment accounts.

  This manipulative scheme didn’t just prey on the goodwill of strangers; it exacted a significant financial toll. The total reported losses amounted to a staggering $5,870 across four incidents, leaving victims not only emotionally distraught but also facing financial hardship due to the deceitful actions of the scammer.

  This case underscores the erosion of trust within communities and the vulnerability of individuals who extend a helping hand in good faith. The exploitation of a young child to facilitate such deceit adds another layer of reprehensibility to an already egregious offense.

  If you’re still keen on lending your phone to those in need while safeguarding your financial security, there are steps you can take. Popular apps like Cash App, Venmo, and PayPal offer security features such as PIN or fingerprint authentication, ensuring that only the phone’s owner can access them. By enabling these measures, you can continue assisting others with phone calls without putting your finances at risk.

  Medicare scammers don’t know you have Medicare 

  

  By Greg Collier

  Medicare scammers are some of the worst. There are few things more heinous than threatening the elderly with the health benefits they earned in life. Scammers often call their elderly victims, posing as Medicare, while trying to get the victim’s Medicare information. This way, the scammers can file fraudulent claims under the victim’s Medicare policy. The victim’s will often be told benign things like Medicare is issuing a new type of ID card. Or they’ll be threatened with the loss of their benefits if the victim doesn’t comply with the caller.

  Here’s something to keep in mind, though. Most of the time, Medicare scammers are calling people blind, hoping they have Medicare. For example, a man in Indiana receives up to 35 calls a day from Medicare scammers. Except, the man hasn’t reached the age when most people enroll in Medicare. The man believes the reason he keeps getting so many scam calls is because he did what you’re supposed to do with a phone, he answered it. Once scammers know that they’ve reached a legitimate number and there’s an actual person on the other end, they continue to spam that person with phone calls. This isn’t strictly for Medicare scammers, either, as many different types of scammers will employ the same calling technique.

  As far as Medicare scams themselves go, please keep this one piece of information in mind. Medicare will not call you on the phone, unless you called them first with some kind of issue or concern. Medicare will not call you, asking you for your Medicare number. They will also not call you to offer you discounts on medical equipment or supplies. If Medicare does need to communicate with you, they will do so exclusively by postal mail. Even if the caller ID says that it’s Medicare calling, unless you called them first, that’s not them.

  Never hand over your phone for candy 

  

  By Greg Collier

  A woman from New York City thought she was being charitable when she handed her phone to a pair of teens who said they were selling candy. Like many of us, the woman said she had no cash on her. Also, the woman didn’t want any candy, but the teens said she could make a donation if she wanted to through payment apps Zelle or Venmo. The woman used Zelle on a regular basis and wanted to make a small donation.

  In order to send someone money on Zelle, you need to know their email address or phone number. The woman asked the teens for a phone number to send the money to, but the teens said they’ll enter the number on the woman’s phone for her. The phone was handed to the teens who entered the phone number on the Zelle app and the woman made a five dollar donation and thought nothing of it. That was until she went to the grocery store and discovered her bank account was empty. Before giving the woman back her phone, the teens sent $1800 from the woman’s account to the phone number they entered.

  There’s another variation of this scam we’ve discussed before. Typically, it involves the scammer claiming they’re in some kind of situation where they need to make a phone call, but their phone is dead. The scammers often claim their car has broken down, but there are other situations they use in this scam. Once the victim hands over the phone to the scammer, the scammer will open up one of the victim’s payment or banking apps and send the victim’s money to another account. The scam has often been called the Good Samaritan scam.

  Getting back to today’s scam, it turns out the whole incident was caught on the security camera footage at the coffee shop where the woman was approached. The victim thought she wouldn’t have any issue getting her money back from her bank since she had proof she was scammed. However, like with most victims who have been scammed through Zelle, Bank of America allegedly refused reimbursement, since to them, it appeared like the victim had authorized the transaction. Also, like many Zelle scam victims, B of A said they would reopen the investigation after the victim took her story to local media.

  To better protect yourself from a scam like this, try to avoid handing your phone over to strangers, and especially don’t hand them the phone while one of your financial apps is open. Please keep in mind that apps like Zelle and Venmo are only supposed to be used between family and friends. If your phone has a fingerprint reader, consider using that to secure your payment apps on your phone, or at least use a PIN.

  Can scammers freeze your phone? 

  

  By Greg Collier

  Sometimes, the better story isn’t what’s in the headline, but what’s buried in the body. For example, take this story from Durango, Colorado. In it, a local coffee shop is targeted in a police impersonation scam that specific to small businesses. Scammers called the shop posing as police, and told one of the shop’s employees that one of their bank deposits was made with fraudulent bills. The employee was told the shop could be in trouble if someone didn’t make a $1500 payment.

  Thinking they were talking to the police, the employee took the $1500 and left the shop to arrange the payment through a money transfer service. The employee was sent a barcode that could be scanned at the point of transfer to send the money. However, sometime during the call, the scammers asked for the phone number of the shop owner, which the employee gave them.

  Another employee saw the first employee leave with the money and called the shop owner. The shop owner tried calling the employee who took the scammers call, but the call function from their phone had been disabled. Could the scammers have remotely disabled her phone just by having her phone number?

  Most of the attacks we’re aware of that can disable your phone, cannot be implemented almost instantaneously like that. In most cases, the user of the phone would need to accidentally download some kind of malware. Or, the scammers would need to do a SIM-swapping attack, which can’t be performed that quickly. So, was the shop owner’s phone attacked, or was their phone freezing just an unfortunate coincidence? Unfortunately, we can’t say for certain, but local police are examining the phone for answers.

  To better protect your phone from such attacks, it’s best to install an antivirus program and occasionally run scans on your phone for malware. As far as the business cam goes, keep in mind that actual police departments and law enforcement agencies will never call you asking for money. That’s not how the police or banks work. If you own a small business, you may want to share this story with your employees.

  Thousands lost in SIM-swapping attack 

  

  By Greg Collier

  If you own a smartphone, how lost would you be without it? We’re not talking about losing your phone in the couch cushions. We mean, how much would your personal life be at risk if your phone was stolen. For many, their smartphone is the only device they need to conduct their lives. For even more, their entire lives are contained in their smartphone. Bank accounts, email, family photos, and schedules are just a few of things that could be accessed through a stolen smartphone. Now, what if we told you that you can lose all these things from your phone without physically losing the device?

  SIM-swapping is a type of cybercrime where an attacker takes control of a victim’s mobile phone number by tricking the victim’s mobile carrier into transferring the number to a new SIM card. Once the attacker has control of the phone number, they can use it to access the victim’s online accounts, such as email, social media, and financial accounts, which often rely on text messaging for two-factor authentication. Then the attacker can not only access your accounts, but they can lock you out of them as well.

  Recently, a man from Colorado lost $24,500 out of his savings account after his phone received a SIM-swapping attack. The victim received an email from his bank that a large transfer was being made, but by the time he was able to contact his bank, the transfer had already gone through. You can almost imagine the shock on his face when he tried to call his bank, only to find out his phone had no service.

  There are several effective ways to protect yourself from SIM-swapping. One is to use an authenticator app instead of relying on text messages for two-factor authentication. Authenticator apps are linked to a device instead of a phone number, making them more secure. Additionally, it’s important to avoid using accurate information for security questions on online accounts, such as high school mascots or pet names, as this information can often be found on social media. Lastly, you can contact your carrier and request that they disallow any device switches on your account, but keep in mind that to unfreeze your account, you may need to visit a carrier store and present identification.

  Don’t hand your phone to strangers 

  

  By Greg Collier

  Before the advent of the smartphone, your wallet used to be the one thing you couldn’t leave the house without. Now, except for drivers’ licenses, just about anything your wallet used to hold can be done though your smartphone. Many smartphone superusers don’t even carry wallets anymore and just use their phone. Thanks to tap to pay platforms like Apple Pay, many don’t need to even carry their debit or credit cards anymore. However, too many smartphone users don’t treat their phone like they would their wallets.

  In a suburb of Memphis, Tennessee, some teenage scammers set up shop outside a supermarket. They claimed to be selling candy to help their football team. Like many of us today, their victims were not carrying cash. When the scammers were told by the victim they didn’t have any cash, the scammers would ask if the victim could support their YouTube channel. The scammers then offer to pull up their YouTube channel on the victim’s phone. What the scammers were really doing was going into the victim’s Cash App and sending the victim’s money to themselves. Some victims were taken for $300 while at least one other lost $1800 to the scam.

  This is a variation of a scam we’ve seen before. Previously, scammers would act as if they needed to call someone as if they were in an emergency situation. The scammers would then use the victim’s unlocked phone to access any number of financial accounts.

  The scam described above is essentially the same as handing someone your wallet so they can put their business card inside it. You wouldn’t just hand your wallet to a complete stranger so you shouldn’t do so with your phone.

  However, if you still want to help people out who may be needing your phone’s assistance, there are ways to protect yourself. Many apps like Cash App and Venmo have security precautions you can enable, so these apps can only be accessed by the phone’s owners. These can be done either by using a PIN or fingerprint scan, depending on the type of phone being used. This way you can still help those in need to make phone calls without risking your finances.

  This phone scam could steal your life 

  

  By Greg Collier

  How much of a panic would you be in if you lost your phone? Can your personal or business email accounts be accessed through your phone? Is your phone locked with a PIN or password? Or is it secured using a fingerprint or facial ID? Do you have banking apps that require a PIN or fingerprint to access? Could any random stranger just pick up your phone and start accessing your money and information? Even if your phone is completely locked down and secure from physical access by outsiders, there’s still a way you can lose all access to your phone without actually losing your phone.

  There is a scam out there that most mobile phones are vulnerable to, and it’s known as SIM-swapping. The name SIM-swapping is a misnomer, since physical access to your phone’s SIM card is not necessary. SIM-swapping works when scammers or identity thieves contact your mobile phone carrier and pose as you. The scammer will use information they’ve found out about you to convince the phone carrier they are you. This is known as social engineering.

  Once the scammer convinces the phone carrier that they’re you, they’ll have the phone company switch your service from your phone to theirs. As soon as that happens, the scammers have direct access to your phone number and text messages. Since most of us who use two-factor authentication have the authorization codes sent to our text messages, the scammers can then access any number of your personal accounts, including your financial accounts.

  This recently happened to a victim from Tennessee. She had received a text message from her carrier indicating a change on her account before her phone service went completely dead. She called her carrier, and another name had been added to the account. By the time she had her service restored, scammers had transferred thousands out of her bank account through the Zelle app.

  There are ways to protect yourself from SIM-swapping. One way is to use an authenticator app instead of using text messages for your two-factor authentication. Authenticator apps are tied to the device instead of being tied to a phone number. Also, when filling out your security questions for online accounts, don’t give the correct answers. Information like your high school mascot or your pet’s name can be discovered on your social media. Lastly, you can contact your carrier and tell them not to allow any device switching on your account. However, to get your account unfrozen, you may have to visit your carrier’s store with your ID.

  Would you fall for this convincing scam? 

  

  By Greg Collier

  A lot of like to think we’re scam-proof, that it’s impossible for scammers to pull one over on us. For example, I received a robocall the other day that said they were calling from Amazon and there had been a $1499.00 charge on my account. I hung up because I knew it was a scam. But just to be certain, I checked my Amazon account and credit card I use for Amazon purchases. Both had no record of any such transaction. Now, that’s a low-pressure scam if you know what to look for. But what if the pressure was intense and immediate. Would you be able to remain calm?

  We’ve discussed the virtual kidnapping scam, or ransom scam, before. This is when scammers call a victim to tell them that they’ve kidnapped a loved one and demand money. In reality, the scammers don’t actually have your loved one hostage. However, even if you might be familiar with the scam, scammers can make it so convincing that in the heat of the moment, you may question yourself.

  A man in Ohio recently received one of these calls. The number that came up on his phone belonged to his mother from Florida. After he picked up the phone, the man heard a male voice with a female voice screaming in the background. The caller stated he carjacked the man’s mother and would harm her if the man didn’t pay the caller. The way that we’ve phrased it, makes it sound so clinical. However, the language the caller used made it seem real. Here are some quotes from the conversation that the man recorded.

  Caller: “Man, guess what? I’m going to start beating your mom, I’m going to start beating her right now.”

  Caller: “If I see the police, I’m going to k*** myself too, but I’m going to take her (expletive) out.

  Caller: “Bro, I’m going to tell you one more time. She ain’t going to be all right if you don’t hurry the (expletive) up.”

  There were other explicit threats of violence as well that we’re leaving out for the sake of civility.

  The caller was demanding payment through Cash App and PayPal. Luckily, the man had trouble remembering his PayPal password. While he was trying to reset the password, he had his wife call his brother on her phone, since his brother lives near his mother. When he got word that his mother was in no danger, he hung up on the scammer. The man even admitted that he panicked and had no idea what to do, even though he made the correct action.

  Scammers will either find us at our weakest or try to put us in that state of mind. Can any of us say we wouldn’t be panicked if we were in this man’s shoes? This is just one of the many reasons we shouldn’t belittle scam victims. There are so many scams out in the wild that any one of us could fall victim to them if the right circumstances emerge. Instead, we should be thanking scam victims who come forward for making us aware of these scams.

  Again, what the man did in this instance was the right thing to do. If you ever receive a phone call like this, try to use a second form of communication to contact the person the caller has claimed to have kidnapped. Kidnapping for ransom is rare in the United States, but you still want to make sure your loved one is safe. Also, don’t be afraid to call the police, as they can be of great assistance in these matters.
