Scenario: an email appears in your inbox where a complete stranger claims to have video footage of you watching porn and asks for $1,000. Your eyes widen. There’s outrage and embarrassment. You reach for your phone — but then you wonder, “Wait. Who do I even call?”

Unfortunately, the answer to that question is a little complicated.

As it turns out, even law enforcement officials can’t agree. The FBI and your local police both suggest that you should call them. But experts warn that in many cases, neither agency will be able to help, especially if the criminal is asking for so little money.

This dynamic really highlights why these kinds of hacks — and yes, the porn scam really happened — are starting to mushroom. And there’s no clear answer on who to call. It’s no surprise that cyberattacks have run rampant across the web, as thieves online find ways to steal credit card information from millions of people without leaving their homes.

“If the people doing it keep the dollar amounts small enough that no individual police department is going to be motivated enough to prosecute, you can collect a lot of money from a lot of people all around the world,” said Adam Bookbinder, the former chief of the US Attorney’s cybercrime unit in the district of Massachusetts.

Sometimes these crimes don’t even involve a hack. An email scheme in which scammers spammed inboxes threatening to blackmail victims, without any evidence, netted $28,000 over two months, researchers from cybersecurity company Digital Shadows found.

“But unless it’s a public concern, there’s a good chance no one will handle it,” said Bookbinder, who’s now a cybersecurity and privacy team member with the Holland & Knight law firm.

Local police

In an emergency, you’re supposed to call 911. If you are a victim of a crime, you should always contact the police.

But here, there’s not much your local police can do for you. For starters, you’d have to show that an actual crime happened, which is much more difficult when it’s digital.

“For example, if someone accesses your Facebook account without your permission, but only uses it to look around at your messages, it’s not enough to meet the threshold for a criminal investigation,” Bookbinder said.

“That’s a misdemeanor,” he said. “Could it be prosecuted? Yes. Is it likely that anyone is going to want to spend the resources on it? No.”

“But if someone used private photos from your Facebook account and threatened to blackmail you with it, then it would be something that police could investigate,” he said.

That’s assuming your local police have the resources to deal with investigating hacks. While more local and state police are improving their computer crime capabilities, it hasn’t happened across the board for every department.

It gets even more complicated if the hack crosses state or national lines. If your account is accessed by a Russian hacker, for example, your local police wouldn’t have the resources to investigate that.

“NYPD is probably an outlier in the resources they have available for investigation,” said Jake Williams, founder of Rendition Security. “But even then, it’s unlikely any law enforcement agency is interested in helping investigate who hacked your Facebook account.”

Homeland Security

If a threat came to your doorstep instead of your digital inbox, the answer would be much simpler: Call the police. But when it’s an online crime, some consider calling 911 a joke.

“I occasionally still hear of companies and locals that call 911 when they believe they’ve been under a cyberattack,” US Department of Homeland Security Secretary Kirstjen Nielsen said during the agency’s Cybersecurity Summit in July.

Nielsen, with a smile, let the remark hang in the air before she told the crowd who they should really call.

“The best thing to do would be to call this center,” she said, referring to the DHS’s National Risk Management Center, a dedicated hub for helping respond to cyberattacks with a focus on critical infrastructure.

But it’s not much help if you’re an average person and not a major company.

“When a person does call the DHS asking for help, the agency will refer them to the FBI,” a DHS spokesman said.

The FBI

The FBI recommends that cybercrime victims call them first — not your local police. The agency has an Internet Crime Complaint Center, where you can file details on what happened and analysts will review the case to determine what actions to take.

Often, though, nothing much is done. The FBI is the best-equipped agency to deal with cybercrime, with its vast resources and plentiful experts, Bookbinder said, but if the complaint isn’t a major case, it likely won’t be investigated.

“They won’t handle most cases of individual hacks unless they’re very high profile or a bunch of money was lost,” Williams said. “It varies from office to office, but most of them we’ve worked want to see $10K stolen before they’ll get involved.”

So is all hope lost? Not necessarily.

“The best way to get a response would be to report the incident to the FBI,” Bookbinder said. Even if your case doesn’t pop up on the agency’s radar, it’s logged into the FBI’s databases of cybercrime complaints. “If enough similar complaints come in, analysts can connect the dots and start building an investigation,” the former cybercrime unit chief said.

“They now have a good-sized crime, and all these people are victims in a case where they do prosecute someone,” he said.

Chances are, you weren’t the only one hit with an email threatening to blackmail you over porn, or whatever. The FBI — and security experts — encourage you to at least report potential cybercrimes in order to help build up a case.

But here’s the thing: The same spamming tactic that cybercriminals are using to cast a wide net may also be their downfall.

Ah, August is here.

And it’s back to school season where both students and parents are making plans for the big return. For some, technology plays a major role.

So here are some quick tips, parents, for when using tech as a tool:

*Plan a technology routine. By creating consistent tech-usage habits, such as limiting computer use to a certain amount of time per day, kids will learn how to better manage both their time and school workload.

*Don’t let technology interfere with sleep — this is crucial for learning.

*Introduce websites that could compliment learning, like Grammarly for writing help or Khan Academy for online lessons.

*LEAD BY EXAMPLE! If you aren’t always on an electronic device, your kids won’t wanna be either. Remember, they’re sponges.

On a more serious note, in addition to monitoring technology use, the FBI is reminding parents this year to review and monitor howtheir children use smartphones. Cell phones are a great way for parents to keep in touch with their children, but parents and kids alike need to recognize the risks that come bundled with that device.

From scams to cyber bullies—if your child is old enough to have and carry a phone, then it’s also time to have a conversation with him or her about potential risks.

Here are 10 basic phone/computer tips to help keep your child safe:

*The phone should default to a locked setting. The only people who should have that access code are the child and the parent.

*Parents should know every password to every device and every password to every app on that device. Sure, you want your kids to have some privacy as they grow up, but they are still kids. You pay the bill, and as long as that child is a child, he or she is your responsibility.

*Check those accounts — as well as instant messaging programs and texts — for disturbing content on a regular basis. You and your kids should have a non-negotiable understanding that this access is a requirement for continued phone use.

*Parents should make sure their child is using appropriate screen names. “Babygirl2005” and “sweet16” may sound cute and innocent, but they can be a beacon to predators.

*Check the privacy and security settings on the phone and the apps. Check regularly to make sure they are up-to-date.

*Learn about how photos are geo-tagged. Even if you are discreet about what you post, your photos could be tagged in the meta-data with your child’s exact location. Do you want just anybody to know what school your child goes to or what field his team uses for soccer practice? You should be able to turn this feature off in settings.

*Teach your kids to never respond to calls, texts, or emails from unknown numbers or people. Scam artists and predators will victimize anyone, regardless of age.

*Talk early and often to your child about the dangers that they may find on the other end of the line. If your child is old enough to carry a phone to school, they are old enough to have a frank discussion with you. Be open and responsive. If your child does encounter a bully or other disturbing content, you want them to feel like they can come to you to for help.

*Talk to your kids about what constitutes appropriate language and photos. One sexually explicit photo can change a life forever. It is crucial that they understand that just because something starts out as a private communication between two people does not mean that it can’t be shared with thousands of people in mere seconds.

*Teach your children to program the privacy settings on social media feeds to the highest level and to reject any “friend requests” from those they don’t know and trust in a face-to-face relationship. Parents should also consider forbidding any new “friend requests” by their kids, without parent approval.
