As if e-commerce companies didn't have enough problems with transacting securely and defending against things like fraud, another avalanche of security problems -- like cryptojacking, the act of illegally mining cryptocurrency on your end servers -- has begun. We've also seen a rise in digital credit card skimming attacks against popular e-commerce software such as Magento.

Google has announced new steps to combat the placement of fraudulent tech support ads on its platform. The company will roll out a verification program in the next few months to ensure that only legitimate third-party tech support providers can place Google ads. There are many legitimate providers that offer local or regional services, or affordable support for out-of-warranty products.

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."

DHS has announced the National Risk Management Center, part of a new effort to combat cyberthreats to the U.S. The new agency's mission will be to defend the critical infrastructure through greater cooperation between the public and private sectors. The center will bring together government experts and industry partners to work out ways that the government can support the partners.

Retailers' biggest worry is increasing e-commerce fraud -- including data breaches, targeted attacks and card-not-present fraud -- according to a report from the Federal Reserve Bank of Minneapolis. Online fraud is one of the biggest challenges facing retailers, with CNP fraud being one of their top worries. CNP fraud will hit $71 billion over the next five years, Juniper Research has forecast.

The healthcare industry has been moving toward medical equipment connectivity to speed up data entry and recording, as well as improve data accuracy. At the same time, there has been a shift toward incorporating consumer mobile devices, including wearables. "The demand for connected devices has increased rapidly in recent years," noted Leon Lerman, CEO of Cynerio.

The DoJ and the CFTC have opened a joint criminal investigation into price manipulation of bitcoin and other cryptocurrencies, according to a report. The illicit tactics reportedly being investigated include spoofing and wash trading. Bitcoin's share prices have been fluctuating wildly over the past year, ranging from $1,800 to almost $20,000, leading to rumors of price manipulation.

The FBI has disrupted a network of half a million routers compromised by the group of Russian hackers believed to have penetrated the DNC and the Hillary Clinton campaign during the 2016 elections, according to reports. The hacker group, known as "Fancy Bear," has been using a malware program called "VPN Filter" to compromise home and small office routers.

A newfound flaw in email clients that use PGP and S/MIME to encrypt messages can be exploited to expose the plain text of the missives, according to a new paper. By injecting malicious snippets of text into encrypted messages, attackers can use the flaw to make the email client exfiltrate decrypted copies of the emails, explained the authors, a team of researchers from three European universities.

"It's only a few times in the history of the U.S. and in specific domains do you have the opportunity to make decisions and have a lasting effect on that domain," said Circadence VP Keenan Skelly. "In terms of information cybersecurity, we're right in the middle of it right now. We're just figuring out what global norms should be."

A flaw in certain electronic hotel door locks could allow hackers to access guest rooms and other secure locations at millions of properties around the world, F-Secure researchers have discovered. Software updates were issued to fix the flaw in the smart locks after F-Secure notified and worked with the manufacturer over the past year. The researchers had found a way to make a master key.

Users of Google's Gmail have been receiving spam that appears to have been sent from their own accounts. Google said it was aware of a spam campaign impacting a "small subset of Gmail users" and was taking measures to protect against it. The attackers used forged email headers to make it appear that users were sending emails to themselves, which led to those emails appearing in their sent folders.

An alarming number of major U.S. retailers, industrial firms, government agencies and other organizations have been hit in a recent wave of cyberbreaches that may signal increasing vulnerability for consumers and businesses alike. The attacks have exposed millions of consumer payment cards to fraud. Cyberthieves have used a variety of methods to infiltrate corporate computer systems.

Nearly a week after it became the target of one of the largest ransomware attacks to date, the City of Atlanta has made progress toward recovery, but it is still far from business as usual. Hackers encrypted many of the city government's vital data and computer systems. Mayor Keisha Lance Bottoms characterized the ransomware attack as "a hostage situation."

The DoJ has charged nine Iranian nationals for engaging in a massive phishing campaign on behalf of the Iranian Revolutionary Guard. The allegations include the theft of $3.4 billion in research and intellectual property from 320 colleges and universities in the U.S. and abroad, as well as from 47 foreign and domestic companies, plus several federal agencies, state governments, and the UN.

A virtual currency hardware wallet with millions of users has been compromised. Saleem Rashid explained how he cracked the firmware on the wallet produced by Ledger using what's known as a "supply chain" attack. That means a targeted device is compromised before any users get their hands on it. The attack on Ledger's $100 Nano S wallet creates a backdoor on the device.

Americans have been targeted on social media by Russian agents on a mission to harvest personal information. The agents pretended to work for organizations promoting African-American businesses as a ruse to obtain personal information from black business owners during the 2016 presidential election campaign. Using names like "BlackMattersUS," the agents set up hundreds of social media accounts.

It's a truism that just like organizations adapt, so too do criminals. Anyone who has ever seen a Wells Fargo commercial knows that there was a time when stagecoaches were a normative method for transporting cash and valuables. But what modern criminals in their right mind would attempt robbing a Brink's truck on horseback? That strategy might have worked well in the days of the Pony Express.

Fraud is a major concern for 72 percent of businesses, according to Experian's Global Fraud and Identity Report. More than 5,500 consumers and 500 business executives in 11 markets around the world participated in the survey. The situation has not been improving, as six out of 10 businesses experienced the same losses to fraud as they did a year ago -- or more.

As beneficial as AI can be, it has its dark side, too. That dark side is the focus of a new 100-page report. AI will be used by threat actors to expand the scale and efficiency of their attacks, it predicts. They will employ it to compromise physical systems and to broaden their privacy invasion and social manipulation capabilities. Novel attacks are to be expected.

If you follow security news, you may have noticed a disturbing trend. Last year, we learned that Uber paid attackers $100,000 to keep under wraps their stealth of the personal information of 50 million Uber riders. More recently, we learned that Hancock Health paid approximately $55,000 in bitcoin to bring hospital systems back online. The payment of ransoms could be more common than it appears.

This holiday selling season may have been a good one for retailers, but every silver lining has a cloud. One shadow will be cast by chargeback fraud, which can occur when shoppers make purchases with a credit card and then request chargebacks from the issuing bank instead of from the merchant. "Merchants bleed $227 for every dollar lost to e-commerce fraud," said NuData's Robert Capps.

As powerful men drop like flies due to their inability to resist abusing their authority, it's clear that the problem is widespread. Similarly, it's likely that we'll find the problem of alleged industrial espionage is not limited to Uber. You see, when people misuse authority -- and the sexual harassment problem is a massive misuse of authority -- folks typically don't just misuse it in one area.

If you are like many, when you saw this headline you likely were surprised BlackBerry was still around. As BlackBerry phones left the market, the company fell out of sight. However, behind the scenes it has been moving into industries like automotive. Also, it remains the leading vendor providing mobile security to our politicians, military personnel and major corporations.

A security flaw in WPA2, the security protocol for most modern WiFi systems, could allow an attacker to steal sensitive data including emails, credit card numbers and passwords, Researchers at Belgian university KU Leuven reported Monday. Depending on the network configuration, the flaw also could allow an attacker to inject or manipulate information in the system.

Malicious code has been discovered in two versions of Piniform's CCleaner housekeeping utility, the company disclosed on Monday. Piniform is owned by Avast, whose security products are used by more than 400 million people. The malware infecting CCleaner could give hackers control over the devices of more than 2 million users. CCleaner is designed to rid computers and mobile phones of junk.

In a rare move, the U.S. Federal Trade Commission on Thursday confirmed that it has opened an investigation into the data breach at Equifax that compromised the sensitive personal information of 143 million U.S. consumers. The FTC announcement came less than a week after Equifax revealed that an unknown party had gained access to names, addresses, Social Security Numbers and other data belonging to nearly half the U.S. population.
