Setting up an internet connection on a computer or smartphone is normally automated and you dont need to delve into doing it manually. But there is one detail worth noting, and that is the choice of DNS and its mode. If you spend a little time on this, you can protect yourself from cyberattacks, ISP spying, unwanted show more ...
content for children, and even ads. What, for example, is Private DNS in Android settings, and how do you use it? DNS and its disadvantages DNS stands for Domain Name Service. It translates human readable web addresses (domain names, for example kaspersky.ru) into digital IP addresses used by computers on the net (185.85.15.34). Almost every internet query starts with a computer contacting a DNS server to translate a site name entered into its IP address. And almost always its be done by the DNS server of your internet provider, while the request to it is neither encrypted nor signed. This insecurity brings many side effects. Your provider always knows which sites you visit and can use this to show you targeted ads. Its easy for the provider to spoof the IP address in its response, showing a completely different site to the one you wanted to see. Youve probably encountered this when connecting to free Wi-Fi in a hotel, cafe, or airport, where the first thing that pops up instead of the site you want is a page requesting authorization or showing ads. The same technology can be used by attackers to control the Wi-Fi network that youre connected to. They can insert fake sites that spread malware or steal bank card information. However, address substitution in DNS responses can have positive practical uses, for example, for parental control services – loading a stub page if theres an attempt to visit undesirable sites. However, this technology isnt very precise, and blocks sites in their entirety – for example, the whole of youtube.com rather than specific bad pages. Therefore, its not used in Kaspersky Safe Kids. But you dont have to use your ISPs DNS server. There are public DNS servers with good reputations, such as those from Cloudflare (1.1.1.1) or Google (8.8.8.8), which you can specify in your internet settings and get rid of some of the problems described above. There are also DNS servers with additional functions – such as blocking access to ad servers. They remove ads in both the browser and other applications. To do this, simply specify the address of the appropriate filtering DNS server in the Wi-Fi settings of your computer or smartphone. Unfortunately, simply changing the DNS address to 1.1.1.1 or 8.8.8.8 doesnt solve privacy issues. An ISP or an intruder controlling the network can snoop on DNS queries, interfere with them, or block access to a third-party DNS. Private DNS and Secure DNS Large corporations and enthusiasts may run their own DNS server and apply any query rules they want to it. In a strict sense, Private DNS is not a high-privacy server – just a private, non-public server. In practice, Private DNS is often run on secure DNS protocols. The Private DNS setting in Android 9 and higher, for example, should be called Secure DNS to convey its essence more accurately. Secure DNS is several competing protocols that differ from ordinary DNS by having encryption. These are DNS over HTTPS (DoH), DNS over TLS (DoT), and DNSCrypt. They differ in communication protocols and ports through which DNS requests are passed. There are still debates about which is better and which is worse. However, sometimes ISPs block access to a third-party DNS, in which case the DoH protocol has the best chance since its more difficult to filter. But its not necessary to go into the finer points of Secure DNS. The main thing is that your smartphone, computer or browser supports at least one of these protocols, and has a DNS server that can be used with it. Theres no shortage of free secure servers – major ISPs (Cloudflare, Google, etc.) support public DNS (1.1.1.1, 8.8.8.8), which you can connect to via both unsecured DNS and DoH/DoT. So your job comes down to enabling this secure access. Already got a VPN? Secure DNS and VPN are complementary technologies. Even if youve enabled a VPN, site name requests may go through an unencrypted DNS channel, and then all of the above risks remain. Some commercial VPN services include their encrypted DNS in the default connection profile, or offer to enable their VPN and third-party secure DNS simultaneously through an app. But this isnt common practice so its worth rereading the information from your VPN provider, or asking technical support. If secure DNS is not offered, it can be enabled in addition to the VPN (see the instructions below). Enable secure DNS Heres the easiest way to enable secure DNS on Android (9 and above): go to Settings, select More connections or Advanced, and find the Private DNS subsection there. Specify the server desired, and the configuration is complete. A slightly mysterious nuance is that Android doesnt accept numeric addresses in this section, so youll need to check the domain name of the desired DNS server with the provider (for example, 1dot1dot1dot1.cloudflare-dns.com). Setting up Secure DNS on Android Apple devices have had DoH/DoT support since iOS 14 and macOS 11. However, theres no built-in setting to enable these protocols, so you need one of the many third-party tools from the App Store that can activate your preferred secure server. You can find them by searching for Secure DNS. Experienced users can install required configuration profiles manually or create them themselves. Windows 10 has had DoH support since version 19628 (from 2020), and you can enable it through these instructions on the Microsoft website. Setting up Secure DNS in Windows 10 Chrome and Firefox browsers can make DNS queries over an encrypted channel, irrespective of OS-level support. Setting up Secure DNS in Google Chrome In some countries, this option is enabled by default, but its better to check it in the browser settings. Setting up Secure DNS in Firefox An important nuance for Kaspersky users: to ensure that your protection is properly configured, first activate protected DNS on the router, OS or in browser settings. Then check that you have the right Kaspersky setting enabled: Settings -> Network Setting -> Traffic Processing. Checking Kaspersky settings for working with Secure DNS Here, you can also specify the specific DoH servers that you plan to use.
Millions of Americans receiving food assistance benefits just earned a new right that they can’t yet enforce: The right to be reimbursed if funds on their Electronic Benefit Transfer (EBT) cards are stolen by card skimming devices secretly installed at cash machines and grocery store checkout lanes. On December show more ...
29, 2022, President Biden signed into law the Consolidated Appropriations Act of 2023, which — for the first time ever — includes provisions for the replacement of stolen EBT benefits. This is a big deal because in 2022, organized crime groups began massively targeting EBT accounts — often emptying affected accounts at ATMs immediately after the states disperse funds each month. EBT cards can be used along with a personal identification number (PIN) to pay for goods at participating stores, and to withdraw cash from an ATM. However, EBT cards differ from debit cards issued to most Americans in two important ways. First, most states do not equip EBT cards with smart chip technology, which can make the cards more difficult and expensive for skimming thieves to clone. More critically, EBT participants traditionally have had little hope of recovering food assistance funds when their cards were copied by card-skimming devices and used for fraud. That’s because while the EBT programs are operated by individually by the states, those programs are funded by the U.S. Department of Agriculture (USDA), which until late last year was barred from reimbursing states for stolen EBT funds. The protections passed in the 2023 Appropriations Act allow states to use federal funds to replace stolen EBT benefits, and they permit states to seek reimbursement for any skimmed EBT funds they may have replaced from their own coffers (dating back to Oct. 1, 2022). But first, all 50 states must each submit a plan for how they are going to protect and replace food benefits stolen via card skimming. Guidance for the states in drafting those plans was issued by the USDA on Jan. 31 (PDF), and states that don’t get them done before Feb. 27, 2023 risk losing the ability to be reimbursed for EBT fraud losses. Deborah Harris is a staff attorney at The Massachusetts Law Reform Institute (MLRI), a nonprofit legal assistance organization that has closely tracked the EBT skimming epidemic. In November 2022, the MLRI filed a class-action lawsuit against Massachusetts on behalf of thousands of low-income families who were collectively robbed of more than $1 million in food assistance benefits by card skimming devices secretly installed at cash machines and grocery store checkout lanes across the state. Harris said she’s pleased that the USDA guidelines were issued so promptly, and that the guidance for states was not overly prescriptive. For example, some security experts have suggested that adding contactless capability to EBT cards could help participants avoid skimming devices altogether. But Harris said contactless cards do not require a PIN, which is the only thing that stops EBT cards from being drained at the ATM when a participant’s card is lost or stolen. Then again, nothing in the guidance even mentions chip-based cards, or any other advice for improving the physical security of EBT cards. Rather, it suggests states should seek to develop the capability to perform basic fraud detection and alerting on suspicious transactions, such as when an EBT card that is normally used only in one geographic area suddenly is used to withdraw cash at an ATM halfway across the country. “Besides having the states move fast to approve their plans, we’d also like to see a focused effort to move states from magstripe-only cards to chip, and also assisting states to develop the algorithms that will enable them to identify likely incidents of stolen benefits,” Harris said. Harris said Massachusetts has begun using algorithms to look for these suspicious transaction patterns throughout its EBT network, and now has the ability to alert households and verify transactions. But she said most states do not have this capability. “We have heard that other states aren’t currently able to do that,” Harris said. “But encouraging states to more affirmatively identify instances of likely theft and assisting with the claims and verification process is critical. Most households can’t do that on their own, and in Massachusetts it’s very hard for a person to get a copy of their transaction history. Some states can do that through third-party apps, but something so basic should not be on the burden of EBT households.” Some states aren’t waiting for direction from the federal government to beef up EBT card security. Like Maryland, which identified more than 1,400 households hit by EBT skimming attacks last year — a tenfold increase over 2021. Advocates for EBT beneficiaries in Maryland are backing Senate Bill 401 (PDF), which would require the use of chip technology and ongoing monitoring for suspicious activity (a hearing on SB401 is scheduled in the Maryland Senate Finance Commission for Thursday, Feb. 23, at 1 p.m.). Michelle Salomon Madaio is a director at the Homeless Persons Representation Project, a legal assistance organization based in Silver Spring, Md. Madaio said the bill would require the state Department of Human Services to replace skimmed benefits, not only after the bill goes into effect but also retroactively from January 2020 to the present. Madaio said the bill also would require the state to monitor for patterns of suspicious activity on EBT cards, and to develop a mechanism to contact potentially affected households. “For most of the skimming victims we’ve worked with, the fraudulent transactions would be pretty easy to spot because they mostly happened in the middle of the night or out of state, or both,” Madaio said. “To make matters worse, a lot of families whose benefits were scammed then incurred late fees on many other things as a result.” It is not difficult to see why organized crime groups have pounced on EBT cards as easy money. In most traditional payment card transactions, there are usually several parties that have a financial interest in minimizing fraud and fraud losses, including the bank that issued the card, the card network (Visa, MasterCard, Discover, etc.), and the merchant. But that infrastructure simply does not exist within state EBT programs, and it certainly isn’t a thing at the inter-state level. What that means is that the vast majority of EBT cards have zero fraud controls, which is exactly what continues to make them so appealing to thieves. For now, the only fraud controls available to most EBT cardholders include being especially paranoid about where they use their cards, and frequently changing their PINs. According to USDA guidance issued prior to the passage of the appropriations act, EBT cardholders should consider changing their card PIN at least once a month. “By changing PINs frequently, at least monthly, and doing so before benefit issuance dates, households can minimize their risk of stolen benefits from a previously skimmed EBT card,” the USDA advised.
