Updated Android malware can hijack calls you make to your bank

Do you remember those TV shows where the villain gets defeated in one season but comes back even stronger in the next? Think “Stranger Things” on Netflix. The malware we’re talking about here is just like that. It’s called FakeCalls, and every time researchers figure out how it infects devices, it evolves with new ways to hide.

Earlier this year, it was reported to be impersonating large financial institutions, and now security researchers have discovered that the malware has gone through another upgrade. It can even hijack the calls you make to your bank using your Android phone.

What you need to know

FakeCalls is a banking trojan that focuses on voice phishing, where victims are deceived through fraudulent calls impersonating banks and are asked to share sensitive information. Earlier versions did this by prompting users to call the bank from within an app that impersonated the financial institution, as reported by Bleeping Computer. However, the latest version, analyzed by Zimperium, sets itself as the default call handler.

The default call handler app manages incoming and outgoing calls, allowing users to answer, reject or initiate calls. Giving these permissions to a malicious app, as you can imagine, carries serious risks.

When a user gives the app permission to set itself as the default call handler, the malware gets the green light to intercept and mess with both outgoing and incoming calls. It even shows a fake call interface that looks just like the real Android dialer, complete with trusted contact info and names. This level of deception makes it really tough for victims to see what’s happening.

“When the compromised individual attempts to contact their financial institution, the malware redirects the call to a fraudulent number controlled by the attacker,” explains the new Zimperium report. “The malicious app will deceive the user, displaying a convincing fake UI that appears to be the legitimate Android’s call interface showing the real bank’s phone number.”

“The victim will be unaware of the manipulation, as the malware’s fake UI will mimic the actual banking experience, allowing the attacker to extract sensitive information or gain unauthorized access to the victim’s financial accounts,” the report added.

The malware can also steal your data

This malware not only hijacks your calls but can also steal your data. It gets access to Android’s Accessibility permissions, which basically gives it free rein to do whatever it wants. The developer of the malware has also added several new commands, including the ability to start livestreaming the device’s screen, take screenshots, unlock the device if it’s locked and temporarily turn off auto-lock. It can also use accessibility features to mimic pressing the home button, delete images specified by the command server, and access, compress and upload photos and thumbnails from storage, especially from the DCIM folder.

6 ways to protect yourself from FakeCalls malware

1) Have strong antivirus software: Android has its own built-in malware protection called Play Protect, but the FakeCalls malware proves it’s not enough. Historically, Play Protect hasn’t been 100% foolproof at removing all known malware from Android phones. Also, avoid clicking on any links in messages or emails that seem suspicious. The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams.

2) Download apps from reliable sources: It’s important to download apps only from trusted sources, like the Google Play Store. The FakeCalls malware infects your phone when you download an app from an unknown link. As an Android user, you should only download apps from the Play Store, which has strict checks to prevent malware and other harmful software. Avoid downloading apps from unknown websites or unofficial stores, as they pose a higher risk to your personal data and device. Also, never trust download links that you receive through SMS.

3) Be cautious with app permissions: Always review the permissions requested by apps before installation. If an app requests access to features that seem unnecessary for its function, it could be a sign of malicious intent. Do not give any app Accessibility permissions unless you really need to. Avoid granting permissions that could compromise your personal data.

4) Regularly update your device’s operating system and apps: Keeping your software up to date is crucial, as updates often include security patches for newly discovered vulnerabilities that could be exploited by malware like FakeCalls.

5) Monitor financial activity regularly: Check your bank and credit card statements often for unauthorized transactions. Set up alerts for any account activity, which can notify you immediately if suspicious activity occurs.

6) Limit sensitive transactions on mobile: Whenever possible, avoid performing high-risk transactions (like large money transfers) on your mobile device, especially if you’re in public or connected to unsecured Wi-Fi. Use a secure computer or contact your bank directly from a verified number.

THE HIDDEN COSTS OF FREE APPS: YOUR PERSONAL INFORMATION

Kurt’s key takeaway

Hackers are constantly upgrading their tactics and finding clever ways to hack your devices and scam you out of your hard-earned money. I really think Android phone manufacturers and Google need to step up their game on security to help keep users from getting hacked so often. I don’t see the same level of malware affecting iPhones.

This digital D&D watch lets you roll a fireball from your wrist

This digital D&D watch lets you roll a fireball from your wrist

Dice hoarding is a common hobby among Dungeons and Dragons players, but I’m betting most won’t have a digital watch in their collection. Alongside displaying the time, day, and date, the Timestop D-20 includes all the dice-rolling features you need to play tabletop roleplaying games directly from your wrist at the push of a button.

The watch allows the wearer to digitally roll a 4-, 6-, 8-, 10-, 12-, 20-, or 100-sided dice, alongside “Advanced Combat” features such as rolling up to 12 dice at once, and D20s with advantage or disadvantage (a fancy way of rolling two dice and taking either the higher or lower results). It’ll also display specific icons when a D20 rolls a 1 or a 20 — known as a “critical failure” or “critical success” respectively in D&D.

“We wanted a fun animation while rolling, but also an overall subdued look so you could ‘take the game with you’ and even wear the watch at the office,” Timestop says in its blog describing the design process. “We included day and date complications with a perpetual calendar so it was still a practical timepiece.”

Pricing starts at $99 and is available in three colors: black, orange, and stainless steel. Shipping starts next year, with stock available for delivery in either January or February.

One feature you won’t find on the Timestop D-20 is an alarm, because alarms “aren’t fun,” according to its creator. Otherwise, it’s water-resistant, features a backlit LCD display, and uses a replaceable coin cell battery that can last up to three years with “typical use.” I’m not sure how many fireball spells would be considered typical, but it certainly offers a more unique way to play than traditional dice or digital dice-rolling apps.

Honda has a plan to build solid-state batteries for EVs

Honda set up a demonstration facility in Japan to show off its plans to mass-produce solid-state batteries at lower costs, which could be crucial to unlocking higher-range, longer-lasting electric vehicles for the future.

Solid-state batteries have been elusive for many companies due to the complexity of scaling up production. The technology swaps out the liquid electrolytes found in current lithium-ion batteries with dry conductive materials, promising higher energy density and longer lifespans. But it will require a whole new production process to be successful.

Honda says it is accelerating research at its new 27,000 square-meter demo facility set up in Sakura City, Japan, and is shortening the time required to make a single unit. The site has full-scale equipment that is split between three buildings: the first for cathode formation and cell assembly; the second for anode formation; and the third for electrolyte activation and module assembly.

The plan includes using a continuous inline mixer that Honda says is “three times faster” than typical cell batch processing. Honda plans to make batteries on this line in January.

Honda is readying its solid-state tech for mass production in the second half of the 2020s. The company’s CEO Toshihiro Mibe has eluded that solid-state batteries will also be the key to unlocking cheaper EVs.

How your browser is spying on you: Hidden dangers lurking behind every click

How your browser is spying on you: Hidden dangers lurking behind every click

A browser is one of the most popular apps we use. It’s the gateway between the internet and its users, translating raw code into something we perceive as a web page and allowing us to interact with the web. It’s safe to say that anyone who uses the internet uses a web browser.

But while this tool is extremely useful, it can also be equally dangerous. For example, clicking malicious links can redirect you to harmful websites that either steal personal information or infect your device with malware.

If you use a search engine like Google through Chrome, it can collect data on your searches, browsing history and even your location (if location services are enabled). Most browsers also use cookies, small files that store information about your online behavior. Let’s discuss the risks associated with web browsers and how to stay safe.

How a browser doubles as spyware

Browsers are much more than simple tools to navigate the web. They are, in many ways, tools for surveillance. While they help you access websites and services, they also track your every move online to feed the ever-hungry advertising industry.

First off, most browsers collect data about your searches, browsing habits and even your location. This data isn’t just stored to “improve your experience,” it’s used to create a detailed profile of you, which is then shared with advertisers who target you with personalized ads.

Google Chrome, for example, is notorious for tracking your activity. As you browse, it feeds data to Google’s advertising engine, allowing it to serve highly targeted ads based on your behavior. This includes everything from your search history to the websites you visit, even down to the smallest detail, like how long you stay on a page.

“Google may share information about you with advertisers, business partners, sponsors, and other third parties,” Google boldly mentions on its privacy policy page.

Browsers also use cookies to keep tabs on you. These cookies track your activity across different sites, even after you’ve left a site. This means that ads you saw on one website might follow you across others, creating a persistent digital footprint. And while cookies can be blocked or deleted, many websites rely on them to function, making it hard to escape this kind of tracking.

Even Incognito mode isn’t safe

Even if you’re using privacy-focused browsers or tools like Incognito mode, they don’t really guarantee privacy. A 2020 class-action lawsuit revealed that Google kept scraping searches by gathering data from users browsing in Incognito through ad tools used by websites, picking up “potentially embarrassing” searches from millions of people. Google then used that data to track web traffic and sell ads.

It’s not just Google. Your internet service provider, the websites you visit and even governments can monitor your browsing activity, even in Incognito mode. All it does is hide your activity from your local browser history.

TOP 6 HIDDEN WAYS A VPN CAN SAVE YOU MONEY NOW

How to protect your privacy

As you all know, web browsers are essential tools for accessing the internet, but many popular options compromise your privacy by collecting extensive data. While Google Chrome is widely used, it tracks significant amounts of user information to power targeted advertising. However, there are several privacy-focused browser alternatives that prioritize user data protection. Also, to enhance your online security and protect your personal information, consider implementing these essential cybersecurity practices.

Keep software updated: Regularly update your operating system, browsers and other software to patch security vulnerabilities. Enable automatic updates whenever possible to ensure you’re always protected against the latest threats.

Use strong, unique passwords: Create complex passwords for each of your accounts and avoid reusing them. Consider using a password manager to generate and securely store strong passwords.

Enable two-factor authentication (2FA): Activate 2FA on all accounts that offer it. This adds an extra layer of security by requiring a second form of verification beyond your password.

Be cautious with emails and links: Avoid opening suspicious emails or clicking on unknown links. These could be phishing attempts designed to steal your information or infect your device with malware. The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

Use secure networks: When using public Wi-Fi, connect through a VPN to encrypt your internet traffic. For sensitive transactions, stick to secure, private networks.

Be mindful of social media sharing: Limit the personal information you share on social media platforms and adjust your privacy settings to control who can view your posts.

VPN: Your first line of defense against browser spying: A VPN (virtual private network) encrypts your internet connection, making it difficult for anyone, including your browser, to track your online activities. By masking your IP address and routing your traffic through secure servers, a VPN not only protects your personal data from prying eyes but also helps you avoid targeted advertising and potential data breaches.

Regardless of whether you are new to VPNs or not, you’ll want to choose trusted VPN providers known for robust encryption and no-log policies to ensure your privacy. Whether for sensitive tasks or everyday use, reputable VPN services will boost both your security and speed. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices.

By implementing these security practices and using privacy-focused browsers, you can significantly enhance your online safety and protect your personal data while browsing the web. Remember, cybersecurity is an ongoing process that requires vigilance and regular updates to your practices.

WHY YOU SHOULD BE USING A VPN TO SAFEGUARD YOUR STOCK TRADING ACTIVITIES

Kurt’s key takeaway

The web browser is an essential tool for accessing the internet, but it also opens the door to a host of privacy and security risks. Whether it’s being tracked for ads, snooped on by your ISP or accidentally stumbling onto a malware-filled site, the risks are everywhere. Tools like Incognito mode or cookie-blocking can help a bit, but they’re not enough to truly protect you. If you’re serious about staying private and secure, you need to up your game. Use a VPN, be cautious about what you click on and stay informed about the ways your browser might be working against you.
