The trick works this way: There you are, utilizing your PC quite recently like whatever other day, when all of a sudden a fly up shows up, notice you that your PC has been contaminated by an infection and you have to call technical support promptly.
On the off chance that you endeavor to dispose of the fly up, it just continues returning. On the off chance that you do call the asserted technical support number, you’re associated with telemarketers who claim to be subsidiary with significant innovation organizations – yet are truly tricksters endeavoring to bilk clients for expensive and superfluous PC repairs or administrations.
When the Federal Trade Commission announced a major crackdown on these scammers last month, it was relying in part on the work of a group of Microsoft researchers and Digital Crimes Unit investigators who used artificial intelligence to help unravel the complex web of technical tricks the scammers were using to swindle users and avoid law enforcement.
The scammers weren’t easy to track down.
“These people are very clever,” said Chris White, a principal researcher at Microsoft’s Redmond, Washington, research lab who collaborated with the company’s Digital Crimes Unit to help track down the scammers.
And they were becoming a real headache for users.
Microsoft’s Digital Crimes Unit, which tracks and prevents cybercrime, receives at least 10,000 complaints a month from around the world about pop-up ads and telemarketers claiming to be legitimate tech support representatives. In general, the scam is more likely to start with a pop-up ad than a phone call, but there are regional exceptions. In Germany, for example, 85 percent of complaints were about tech scams that originated with a phone call.
The majority of the complaints appear to be coming from people 50 and older, but younger users aren’t immune. About 30 percent of the people who filed a complaint and gave their age said they were under age 49, according to the latest data from the Digital Crimes Unit.
Because not everyone reports an attempted attack, experts believe the total number of complaints represents only a small fraction of the people targeted by the scams.
Using AI running in the cloud to find scams
The reports from customers were helpful, but the team was still having trouble catching what White calls the “biggest fish” – the masterminds behind some of these large-scale operations.
That’s because the victims may only have limited information to help in the investigation, such as a phone number that’s been disconnected. Also, few victims capture screen shots of the original scam pop-up.
Finally, the scammers themselves are very good at compartmentalizing their business, separating the telemarketing operation from people building the pop-ups.
“We had a bunch of customers who were reporting scams but didn’t know who scammed them,” said Courtney Gregoire, assistant general counsel for the Digital Crimes Unit.
To catch the scammers, Microsoft sleuths first had to figure out where the attacks were coming from – no easy task, since they often only used an IP address, or virtual home, for a day or less before moving on to another location to avoid being caught.
To find them, the team created a model that looked for content that behaved in a way that was consistent with the scam, such as creating a pop-up that refreshed in microseconds to give the appearance it wasn’t going away. Then, the team scoured the web for those sites and captured screen shots of all the content that could potentially be a scam.
It would be impractical, if not impossible, to manually scan through the hundreds of thousands of questionable pieces of content they found, so the team turned to a branch of AI called machine learning to sort the data.
With machine learning, a system can learn to recognize something – such as similar words or images – as it’s given more data that shows what it’s looking for. With this project, the team used custom AI tools, running on Microsoft’s Azure cloud computing platform, to look for image similarity, content and other visual clues that would determine the chances that the pop-up was relevant to the fraud investigation.
Then, they used the computer vision API from Microsoft Cognitive Services to scan the ads for phone numbers and other bits of information that could provide clues as to their origin.
Without AI tools and cloud computing, White said they would likely have had to approach the problem slowly and manually, using thousands of employees to document complaints and try to manually figure out whether the data they’d gathered pointed to a pattern.
With the technology, they were able to more quickly track the fast-moving scammers and devote investigator time to higher value work, like finding the connections that could lead to those big fish.
“What we’re able to do is address the problem at the scale it’s happening, and provide the mechanisms for us to do something about it,” White said.
Making data understandable
The AI tools made their job faster, less costly and more precise, but then White and his team had another challenge: How to present their findings in such a way that lawyers and non-tech experts could understand it and decide what action to take.
White has had past involvement with this test. Prior in his profession, he’d been sent to Afghanistan to utilize information investigation to help with the U.S. protection methodology there. On the ground, he understood that his information wouldn’t help much unless he could figure out how to exhibit it that seemed well and good to commanders rather than PC researchers. He took in the estimation of visual devices, for example, diagrams and charts.
With the technical support trick, the group expected to make their discoveries justifiable to legal counselors and law implementation authorities. To do that, they utilized an information perception apparatus called Power BI to make intelligent, straightforward outlines and information representations. The information examination helped law requirement comprehend examples, for example, how old the clients were, what geographic ranges the tricksters were focusing on and which approaches they were taking in those zones.
The discoveries helped the FTC in its crackdown, and it additionally helped government authorities show signs of improvement feeling of how the issue was influencing individuals..
In the mean time, the con artists are continually searching for new techniques to trick clients and abstain from getting got, which implies White and the Digital Crimes Unit are proceeding to enhance their strategies for following and battling them. Gregoire said the organization has a solid sense of duty regarding proceeding to battle these tricks.
“We have a business enthusiasm for doing this, and we have a worldwide decent enthusiasm for doing this,” Gregoire said.
The AI and data analysis tools Microsoft is using to track down tech support scammers are similar to the ones that White and his team are using for other applications that require people to scan large amounts of what’s known as unstructured data – things like websites – to look for patterns.
For example, the team has used similar AI tools, combined with Power BI, to help people without technical expertise create systems that can scan online news and social media to understand patterns that may affect their company or organization.
White will be discussing the work his team is doing to help people make sense of big sets of data at the Data Summit in Dublin, Ireland this week.
For White and other researchers, it’s exciting to see the AI technologies and data analysis that were confined to research labs become available and useful to anyone.
