Android banking Trojan evolves to evade detection and strike globally
Android banking Trojan Medusa has returned after almost a yearlong hiatus and is now even more dangerous. The new variant of the Trojan is lightweight and requests fewer device permissions to avoid detection.
First identified in 2020, Medusa is a Turkish-linked banking Trojan that initially targeted Turkish financial institutions.
It expanded rapidly by 2022, launching major campaigns in North America and Europe, causing significant monetary harm. Medusa’s new variant is now targeting Android users across the globe, including those located in the U.S., Canada, Spain, France, Italy, the U.K. and Turkey.

How does the Medusa Android Trojan evade detection?
Since July 2023, Medusa attacks are back with a new version. Cybersecurity experts from Cleafy found a spike in the number of installs of an app called “4K Sports.” This app is being used by hackers to put malware on people’s Android phones. The new malware is an upgraded Medusa with big changes in how it works.
It asks for fewer permissions, making it sneakier. It still requests Accessibility Services, which is a big red flag. Android’s Accessibility Service is a powerful tool that helps people with disabilities use mobile devices more easily. When you grant an app Accessibility permissions, you’re essentially giving it the ability to do whatever it wants on your phone.

Cybercriminals are aware of this, so most malware that infects your phone will ask for Accessibility permissions. You should be immediately suspicious when an app requests permissions in this area. Medusa’s new variant also requests Broadcasting SMS, Internet Foreground Service and Package Management permissions.
The Android Trojan now has 17 fewer commands than before but adds five new ones, like setting a black screen overlay, taking screenshots and more.
Cleafy reveals that hackers are using not only the 4K Sports app to install Medusa but also fake apps like Google Chrome, InatTV, Purolator and 5G. In the U.S., Chrome, InatTV and Purolator are the main apps being misused by these hackers.

What is the scale of the Medusa cyberattack?
Medusa is going after people all over the world, including the U.S. and Europe. Cleafy found two different Medusa botnet groups, each working in its own way.
The first group, with botnets named AFETZEDE, ANAKONDA, PEMBE and TONY, mainly targets people in Turkey but also hits Canada and the U.S. They use Medusa’s usual tricks, like phishing, to spread the malware.
The second group, including the UNKN botnet, shows a change in Medusa’s strategy. It mainly targets European users, especially in Italy and France. Unlike the usual variants, some of these new ones were installed through apps downloaded from untrusted sources. This means the hackers are trying new ways to spread the malware beyond the usual phishing tactics.

ANDROID BANKING TROJAN MASQUERADES AS GOOGLE PLAY TO STEAL YOUR DATA
10 ways you can protect yourself from the Android banking Trojan
While a Trojan is hard to detect and can be dangerous once it enters your phone, there are several things you can do to protect your data.
1. Be cautious of phishing attempts: Be vigilant about emails, phone calls or messages from unknown sources asking for personal information. Avoid clicking on suspicious links or providing sensitive details unless you can verify the legitimacy of the request.
2. Have strong antivirus software: Android has its own built-in malware protection called Play Protect, but it’s not enough to stop all malicious software. Historically, Play Protect hasn’t been 100% foolproof at removing all known malware from Android phones. 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. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.
3. Download apps from reliable sources: It’s important to download apps only from trusted sources like the Google Play Store. They have strict checks to prevent malware and other harmful software. Avoid downloading apps from unknown websites or unofficial stores, as they can pose a higher risk to your personal data and device.
4. Use an identity theft protection service: Identity Theft companies can monitor personal information like your Social Security Number (SSN), phone number and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.
One of the best parts of using some services is that they might include identity theft insurance of up to $1 million to cover losses and legal fees and a white glove fraud resolution team where a U.S.-based case manager helps you recover any losses. See my tips and best picks on how to protect yourself from identity theft.
5. Monitor your accounts: If you think you have been affected by the banking Trojan, regularly review your bank statements, credit card statements and other financial accounts for any unauthorized activity. If you notice any suspicious transactions, report them immediately to your bank or credit card company.
6. Enable SMS notifications for your bank accounts: By enabling SMS notifications, you can monitor your accounts for any unauthorized transactions.
7. Set up two-factor authentication (2FA): 2FA is an extra shield that prevents hackers from accessing your accounts.
8. Use a password manager: A password manager can help you create and store strong, unique passwords for all your accounts, reducing the risk of password theft.
9. 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 Trojans.
10. Be wary of granting permissions: Carefully review the permissions requested by apps. If an app asks for more access than it needs for its functionality, it could be a red flag.
HOW TO REMOVE YOUR PRIVATE DATA FROM THE INTERNET
Kurt’s key takeaways
Hackers behind Medusa have made the malware hard to detect. They use apps that look legitimate to get the malware onto your phone and steal your personal data and sometimes your money. As a rule of thumb, only download apps from the Google Play Store. Google ensures it only allows secure apps on its platform and is safer than any other app store.

Meta might be the next company to make an always-on AI wearable. The company is working on prototype “super sensing” always-aware smart glasses that could continuously record audio and snap photos “every few seconds,” according to the Financial Times. The wearer could then ask Meta AI about the captured audio and images.
However, the images and audio might not be directly available to the user. Here’s how the FT describes one way the glasses could use the data:
In one proposed system, raw footage and audio would not be stored by Meta or made available to the user, several people said. Instead, the metadata from that audio and images would be extracted and uploaded to the server for Meta’s AI to query, which proponents argue would have fewer privacy implications.
But currently, Meta is planning for the LED recording indicator to remain off in “super sensing” mode, the FT reports. In a July 2025 whitepaper, the company said that it would reserve the LED indicator for “active capture” scenarios where the user is saving photos or videos, and leave it off during “AI Feature” use — such as scanning a menu — to avoid users becoming too used to the indicator. (If the indicator was on during the “super sensing” mode, it might also be harder to know when the glasses are actually recording video.)
Meta is also discussing if it would use the captured data for training its AI models. It may also bring the “super sensing” features to glasses it has already released, the FT says.
“While we don’t comment on internal prototypes, we’re committed to getting our glasses right because they need to be loved by both people wearing them and those around them,” Meta spokesperson Dave Arnold says in a statement to The Verge. Arnold also notes that “Our approach has been to develop new technologies that will help people throughout their day, with privacy built in from the ground up.”
Meta hasn’t been shy about some type of always-aware glasses being a possibility. CEO Mark Zuckerberg, in the company’s Q1 2026 earnings call, said that he was “really excited to see the glasses evolve from being able to answer questions to being able to be a personal agent that’s with you all day long, helping you remember things and achieve your goals.” In a March blog post about new Ray-Ban Meta glasses, the company wrote that “with ongoing software updates, Meta AI on glasses will transition from something you have to prompt with a question each time, to a more continuous, in-the-moment assistant that can help throughout the day.”
Even though they haven’t been officially announced yet, Samsung is giving you a chance to save some cash when you preorder what we’re expecting to be the brand’s updated Galaxy Z Fold phones. The next Galaxy Unpacked event will take place on July 22nd, 2026, and features the tagline “A new shape unfolds.” In addition to seeing updated versions of the existing Flip and Fold form factors, we anticipate the debut of a new, wider foldable phone. If you register your interest ahead of time and end up preordering one of the new phones shortly after they’re announced, Samsung will give you a $30 store credit at checkout.
There are some caveats to this offer. You have to use the credit when you preorder the phone. No saving it for later. Also, the credit can’t be applied to the cost of the phone either, so you’ll have to put it towards the cost of accessories or extra services. Samsung specifically calls out that select Galaxy rings, earbuds, watches, and tablets are eligible, or you can use it to help pay for Samsung Care Plus.
There are no downsides to registering your interest, so if you think you might be interested in buying one of the upcoming phones, it’s worth filling out the form. As long as you use the same email during checkout, the credit will be automatically applied.
Anthropic’s new AI model raises alarms over safety, cybersecurity concerns
Matt Shumer, co-founder and CEO of OthersideAI, details Anthropic’s new AI model, Mythos, on ‘The Sunday Briefing’. The model’s “emergent capabilities” to find software vulnerabilities autonomously raised alarms, prompting Anthropic to restrict public access. Shumer explains the proactive move of granting major companies and the US government early access to Mythos for cyber defense, anticipating future threats to critical infrastructure and national security.

A security update rarely feels dramatic. You see the alert, promise yourself you will install it later and then go right back to whatever you were doing. This time, Apple is giving you a stronger reason to pay attention.
Apple released iOS 26.5.2, iPadOS 26.5.2 and macOS Tahoe 26.5.2 on June 29, 2026. The updates include security fixes for vulnerabilities tied to the kernel, WebKit and WebRTC. Apple says these fixes were first made available through the iOS 26.6, iPadOS 26.6 and macOS Tahoe 26.6 betas before being pushed out early to everyone.
That is the part that should make you pause. Apple usually rolls many security fixes into larger software updates. This time, the company moved faster.

Why Apple released this AI security update early
Apple reportedly accelerated the updates because artificial intelligence can help speed the creation of malicious hacking tools. Once a fix appears in a beta, attackers may be able to study it, reverse-engineer the weakness and move faster than before.
Apple said there was no evidence that the newly patched vulnerabilities had been exploited. Still, the company wanted to shrink the time between when fixes were first visible and when they reached your devices.
That is a major shift. It suggests Apple sees AI as a force that changes the timing of security. A flaw that once gave defenders more breathing room may now become a race.
What Apple fixed in iOS 26.5.2
Apple’s iOS 26.5.2 and iPadOS 26.5.2 notes list fixes for iPhone 11 and later, along with several supported iPad models. The security content includes kernel vulnerabilities that could let an app crash the system, corrupt kernel memory or leak sensitive kernel state.
The update also fixes multiple WebKit issues. WebKit powers Safari and web content inside many apps. Some of these flaws involved malicious web content that could lead to crashes, memory corruption, data leaks or sandbox escapes.
Apple also fixed WebRTC issues that could be triggered by malicious web content and lead to Safari or process crashes.
For Mac, Apple lists macOS Tahoe 26.5.2 as the current release. If your Mac runs macOS Sonoma or macOS Sequoia, Apple also lists Safari 26.5.2 as a June 29, 2026, security release.

Why AI hacking tools change the security race
AI can help legitimate researchers find bugs faster. That is good when the work leads to stronger software and responsible disclosure. However, the same general capability can also help bad actors move faster. A criminal does not need to understand every line of code if an AI tool can help summarize a patch, compare software changes or suggest where a weakness may be hiding.
That is why Apple’s move is important. It shows that big tech companies may need to release security fixes sooner and more often, even when those updates do not include flashy new features. The wider AI world adds pressure here. Frontier AI companies have released or tested systems with stronger coding and cybersecurity capabilities. Some models are available only through limited previews, approved access or extra safeguards because of their potential cyber use.
Similar efforts are also emerging outside the United States. Several international AI labs and security companies now promote models designed to find vulnerabilities, analyze code and assist cyber defense. The takeaway for you isn’t that AI is automatically bad. The real point is speed. Security teams, attackers and AI tools are now moving on a shorter clock.
How to update your iPhone or iPad
Before you update, plug in your device and connect to Wi-Fi. You may also want to back up your iPhone or iPad first.
Then do this: Open Settings > General > Software Update > Download and Install.
After the update finishes, go back to Settings > General > Software Update > Automatic Updates. Make sure automatic updates are turned on. Apple also lets your device automatically install system file updates that improve security without changing the full software version. If you do not see the update right away, check again later. Apple releases updates in stages, and your device also needs enough battery and storage.
How to update your Mac
On a Mac, start with a backup. Then click the Apple menu > System Settings > General > Software Update . Choose Update Now if macOS Tahoe 26.5.2 appears.
Next, check your background update settings. On macOS Tahoe 26 or later, go to Apple menu > System Settings > General > Software Update . Click the More Info button next to Automatic Updates and make sure Install system data files and security updates is turned on.
If your Mac runs Sonoma or Sequoia, look for Safari 26.5.2 in Software Update as well. That Safari update may be the protection your Mac needs if you are not on Tahoe.
BEWARE OF HACKERS SHOWING UP PRETENDING TO BE IT
What this Apple security update means to you
You may see more security updates that feel sudden or small. That can be annoying, especially when you are busy or your device needs to restart.
Still, these updates are becoming more important. Apple is reacting to a world where AI can help shorten the time between a public fix and a possible attack.
So, when your iPhone, iPad or Mac asks you to update, do not treat it like background noise. The update may be closing a door someone else is already trying to find.

How to stay safe after the Apple security update
Installing the Apple AI security update is the best first move. After that, tighten a few habits that make attacks harder.
1) Keep your apps updated
Your operating system is only part of the security picture. Outdated apps can still create risk, especially if they handle messages, web links, photos, files or account logins. Open the App Store and install available updates regularly.
2) Watch out for suspicious links
Be careful with links in texts, emails and social media messages. WebKit and browser flaws are a reminder that malicious web content can be part of an attack. When in doubt, open the official app or website yourself instead of tapping a link.
3) Use strong passwords and two-factor authentication
Use strong, unique passwords for every account and store them in a password manager. Then turn on two-factor authentication (2FA) wherever possible. If one password gets exposed, you do not want it opening the door to your email, bank or Apple account.
4) Use strong antivirus protection
Use strong antivirus protection on your Mac and other connected devices. It can help catch malicious files, phishing attempts and suspicious activity before they do damage. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.
5) Back up your data regularly
Back up your iPhone, iPad and Mac before problems hit. A recent backup can help you recover faster if an update fails, your device gets stolen or malware locks you out of important files. CyberGuy’s guide to backing up your devices walks you through ways to protect your files using cloud storage, an external drive or both.
6) Use a personal data removal service
Use a personal data removal service to reduce how much of your personal information is floating around online. Data brokers and people-search sites can expose your name, address, phone number and relatives. Scammers can use those details to make phishing messages feel more believable. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting CyberGuy.com.
Kurt’s key takeaways
Apple’s early security release shows how fast the cyber threat landscape is changing. The company says there is no evidence these newly patched flaws were exploited, but it still moved the fixes out before the wider 26.6 release. That tells me the old habit of waiting weeks to update is getting riskier. AI can help defenders, but it can also help criminals study weaknesses faster. My advice is direct: update your Apple devices now, turn on automatic security updates and stop putting off patches that protect the phone and computer you use every day.
Do you think AI will make your devices safer because companies can find flaws faster, or more vulnerable because hackers can move faster too? Let us know by writing to us at CyberGuy.com.
