As fearful Californians shelter in place and shudder over every apocalyptic news story about the coronavirus, scammers see something else — dollar signs.

Think about it: Parents working from home while managing school-aged children are distracted. They grow weary and let their guard down, and open an email they shouldn’t have. Many scared Baby Boomers, the most vulnerable to the worst effects of the virus, are looking for miracle cures and good news from helpful sources, even strangers.

The FBI considers California one of the states most vulnerable to coronavirus scammers, along with New York and Washington. This includes spoofing or phishing emails, texts and aggressive phone calls.

There’s also been an explosion in false advertising of products claiming to prevent or cure COVID-19, the disease caused by the coronavirus, leveraging the distrust many Californians may have of official government health resources such as the Centers for Disease Control and Prevention (CDC). The FBI arrested a California actor March 25 for selling what he claimed were an injectable "cure" and "prevention pills," and seeking investors from among his 2.5 million Instagram followers.

“As if watching out for the coronavirus wasn’t stressful enough, Californians must be extra diligent to keep their guard up against scammers prospering over this pandemic,” said Harry Kazakian, a Los Angeles security and investigative expert and former EMT/paramedic.

Kazakian said there are several relatively easy steps you can take to stay safe.

“For instance, you can hover your mouse over an email address or a link, in Outlook or a web browser, and a small window will pop up to show where the link goes to,” Kazakian said. “If the real link does not match with the sender or with what you expect, don’t click it.”

Remember, Kazakian added, a legitimate website link should end with the company’s name and not a bunch of numbers or letters that make no sense. For example, an email from the CDC will always ends with @cdc.gov. An email claiming to come from the CDC, but ending in anything else is a scam, he said.

The FBI advises you to be wary of any business, charity, or individual requesting payments in cash, by wire transfer, gift card or through the mail.

In addition, the sudden appearance of “treatments” on the market may not only separate the gullible from their money, those treatments may also pose a genuine risk to their health.

“We’ve seen an explosion in colloidal silver, ionic silver, herbal teas, and even essential oils like eucalyptus, all hocked as coronavirus treatments or cures,” said Robert Tauler, a Los Angeles attorney who specializes in false advertising law and supplement litigation. “There is no evidence to support their claims, and they must by law make that crystal clear to consumers.”

Here are some more tips from the experts to guard against computer scams:

Don’t trust “Coronavirus” or “COVID-19” subject headers – Those words are the most “clickable” online enticements right now, because the pandemic is top-of-mind, Kazakian said. Clicking on emails and texts with these words may enable cybercriminals to steal personal information or, ironically, infect your computer or smartphone with a virus.

Beware of fake charity come-ons – Your goodwill can make you more vulnerable. Sharing a credit card number to donate to something like “International Children’s Coronavirus Relief Fund” could cost more than you banked on. Remember, at this time, there are no vaccines and no cures.

Let it go to voicemail – Criminals can be pretty shrewd at making their phone calls appear to originate from your area code. If you don’t recognize the number, or even if your smartphone suggests that the incoming call originated with a local utility or agency, always let it go to voicemail. “Most robocalls will not leave a message, so you can just block the number,” Kazakian said. Government agencies, including Medicare, Social Security and the IRS, will never call or leave you a message.

Know who you’re buying from – This isn’t the time to buy face masks online from a seller you’re unfamiliar with. Besides the obvious risk of handing over crucial personal information, you may unwittingly buy used, defective or counterfeit items. That mask may do nothing to help. That dozen bottles of hand sanitizer may never arrive. And avoid opening accounts with online services you’ve never heard of. Do your research. This could be another way of getting your information.

There is no immunization or "home test kit” – There are no approved home test kits for coronavirus and no vaccines, period. Any offer claiming otherwise is a scam. Keep checking CDC.gov to stay informed.

Fraudulent supplements are flooding the market – The dangers of taking herbal products promising to treat a novel and deadly disease cannot be understated. “At worst, consumers without access to medical care may forego medical treatment based on false claims,” Tauler said. “At a minimum, consumers will shell out hard earned money for fake products that will do nothing to keep them safe.”

Fake remedies could kill you – If you’re taking prescription medications, products falsely touted as coronavirus cures could interfere with their effectiveness. And keep in mind that these products may arrive contaminated with other ingredients or pharmaceuticals not listed on the label, especially products coming from China, where factory production guidelines are lax or ignored.

One more thing – Older people are more likely to fall for scams, and that makes them a favorite target for criminals and charlatans. Regularly check in with the senior citizens in your life and look for warning signs, such as the sudden appearance of a new “friend” who calls or emails often, or some urgent business at a bank or Western Union. Help your senior family and friends learn to block suspicious emails, phone numbers and texts. Enlist help from your local senior advocacy organization if you need someone to back you up.
