Fraudsters have been stealing online advertisers blind -- to the tune of $23 billion, based on a report from Cheq. Indirect economic and social costs might increase the total to $30 billion. Marketers have been wasting billions of dollars on digital ads that never reach buyers' eyes. Up to 30 percent of ads are impacted by fraud that affects 21 trillion online ads each year.

Payment processing company Stripe has launched Chargeback Protection, a machine learning-based system to limit the impact of fraudulent credit card transactions on merchants. A chargeback is a demand by a credit card provider for a retailer to make good on a fraudulent or disputed transaction by repaying the full purchase amount plus a chargeback fee.

Building and sustaining a brand has gotten more challenging. The global marketplace, empowered by the Internet, has delivered a raft of opportunities to businesses, but it also has opened the door for challenges. These challenges include increased competition as the result of a wider market, and increased possibilities for brand abuse. Added to that mix is the ever-present cyberthreat.

Is anyone surprised to learn that in just the first quarter of 2019 more than $1.2 billion worth of cryptocurrency was stolen? Probably not. This story follows the old line from bank robber Willie Sutton who is credited with saying that he robbed banks "because that's where the money is." So not much has changed. Cryptocurrencies are not exactly money, though, even if they do have a market value.

Many users of Facebook's WhatsApp messaging software are scrambling to patch the program in response to news of a flaw that allowed spyware to be installed on mobile phones running Android and iOS. "This new type of attack is deeply worrying and shows how even the most trusted mobile apps and platforms can be vulnerable," said Mike Campin, vice president of engineering at Wandera.

Baltimore officials have admitted that the city government once again has been victimized by ransomware -- the second such attack in just over a year. City computers reportedly were infected with the RobinHood ransomware virus. Hackers told city officials that they would unlock the computers in return for payment of three bitcoins per system, or 13 bitcoins for the entire system.

Spring may be my favorite time of year. The snow is melting, the sun is shining, and the air smells just a little bit fresher. It's as though the world is setting an example for the rest of us, letting us know that it's time to start fresh. It's time for spring cleaning -- and in the security world, spring cleaning means more than just wiping down countertops and lighting a few scented candles.

Consumers are becoming increasingly concerned about the hacking of their devices and data as they hear about more data breaches and have their own experiences with issues such as ransomware, identity theft and botnet attacks. Concerns about data security also have been shown to increase with ownership of more connected devices. Currently, U.S. broadband households own an average of 10.4 connected devices.

Cybersecurity experts at Microsoft's Windows Defender Security Intelligence Team this week reported their discovery of two new email-based phishing campaigns. One targets Amex users while the other targets Netflix customers. Both campaigns reportedly are very well-crafted, featuring legitimate logos and even fill-in forms that closely mimic those on the respective company's own websites.

A new cryptovirus called "B0r0nt0K" has been putting Linux and possibly Windows Web servers at risk of encrypting all of the infected domain's files. The new ransomware threat and the ransom of 20 bitcoins -- about $75,000 -- first came to light last week in a forum post. A client's website had all its files encrypted and renamed with the .rontok extension appended to them, the forum user indicated.

The e-ticketing systems of eight airlines, including Southwest Airlines and Dutch carrier KLM, have a vulnerability that can expose passengers' personal data, mobile security vendor Wandera has reported.

The Samsung Galaxy S10, scheduled for launch on Feb. 20, likely will incorporate a cryptocurrency wallet. "Samsung has a long history of throwing everything it can think of, technology-wise, into its flagship Galaxy S series smartphones," remarked Ken Hyers, research director at Strategy Analytics. Most users aren't fully aware of their Galaxy S phone capabilities, he noted.

A new year means a fresh start, but it doesn't mean that old threats will go away. In fact, in the world of cybersecurity things could get far worse before they get better. Cybercrime continues to increase, as it allows nefarious actors to operate at a safe distance from victims -- and more importantly, law enforcement. Cybercrime often doesn't get the same attention as other types of crimes.

E-commerce fraud is an ongoing problem for online merchants and credit card companies. It has been growing at twice the rate of e-commerce sales.

"We are working rapidly to investigate the situation."

With the holidays fast approaching, are you looking to buy presents online? The holiday season has become synonymous with online shopping. This isn't really surprising as physical stores usually attract crowds of deal hunters. This often conjures up images of throngs of people waiting in line outside the store, some even camping out. This activity is tolerable for some and even fun for others.

The malicious code was added to StatCounter's site-tracking script last weekend, he reported. The malicious code hijacks any bitcoin transactions made through the Web interface of the Gate.io cryptocurrency exchange.

Do you take your online privacy seriously? Most people don't. They have an ideal scenario of just how private their online activities should be, but they rarely do anything to actually achieve it. The problem is that bad actors know and rely on this fact, and that's why there's been a steady rise in identity theft cases from 2013 to 2017, often resulting in loss of reputation or financial woes.

We made it. The holiday shopping season is here once again! This is a great opportunity for you as an e-commerce retailer. If you're like many other merchants out there, the run-up to Christmas is one of the most profitable, and busiest, times of the year. You may need some extra help to handle the surge in traffic and maximize your return. That means hiring seasonal employees.

Microsoft has torpedoed websites designed to steal credentials from visitors to two Republican Party think tanks. The malicious websites were among six the company took down last week. A group of hackers affiliated with the Russian military created the sites, according to Microsoft. It apparently was the same group that stole a cache of email from the DNC during the 2016 presidential campaign.

There's a lot of hype around artificial intelligence as the greatest thing since sliced bread, but will AI really help with cybersecurity? Criminals who run cybercriminal businesses also are capable of using the AI to commit crimes. It's logical that if one person is smart enough to develop cyberprotection technologies that utilize AI, then thoughtful, creative criminals can use it too.

"If you think about Internet threats like phishing and botnets and malware -- all of those start with a DNS -- a domain name system. And so every kind of nefarious act leaves footprints and fingerprints in the DNS. That's something that cannot be faked," said Farsight Security COO Alexa Raad. For example, "a lot of the new domain names that are registered are typically registered with bad intent."
