Android flaw lets hackers unlock phones in under a minute
NEWYou can now listen to Fox News articles!
Your phone lock screen is supposed to be your last line of defense. If your device gets lost or stolen, that PIN or passcode should keep strangers out of your photos, messages and financial apps. But researchers have found a serious flaw that can break through those protections on certain Android phones in less than a minute.
Once exploited, attackers can recover your phone’s PIN, unlock encrypted storage and even extract sensitive data such as cryptocurrency wallet seed phrases. Security researchers estimate that roughly one in four Android phones could be affected, particularly budget phones.

ANDROID FIXES 129 SECURITY FLAWS IN MAJOR PHONE UPDATE

All about the Android hacking flaw
A newly disclosed vulnerability, tracked as CVE-2026-20435 in the National Vulnerability Database, affects some Android phones powered by MediaTek, a major smartphone chip maker based in Taiwan that competes with companies like Qualcomm. These phones use a security component called Trustonic’s Trusted Execution Environment (TEE), which is designed to keep sensitive data, such as encryption keys, protected from the rest of the system.
It stores cryptographic keys that help keep your device encrypted and secure, even if someone tries to tamper with it. However, security analyses of the vulnerability indicate that these protections may be bypassed on affected devices.
By connecting a phone to a computer using a USB cable, an attacker with physical access may be able to exploit the flaw during the early boot process, potentially exposing sensitive data before full security protections are enforced. Think of it like accessing the master key before the safe door even closes. Once attackers gain access to these low-level components, they may be able to access encrypted storage without needing your PIN.
In a worst-case scenario, this type of access could allow attackers to extract highly sensitive information, including personal photos, stored passwords, private messages, financial data, and crypto wallet credentials. If seed phrases for crypto wallets are exposed, attackers could drain funds permanently.
What are Android makers doing about this
There’s limited action manufacturers can take on their own since the issue originates at the processor level, which is manufactured by MediaTek. The company says it has released a firmware patch addressing the vulnerability. However, the update must still be distributed by individual phone manufacturers through security updates. Depending on the device and whether it is still supported, that update could arrive quickly or not at all.
The good thing is that this attack requires physical access to the phone and a USB connection to a computer. That means it cannot be done remotely over the internet. However, if your phone is stolen, briefly confiscated, or even taken during a repair, the attacker could potentially extract sensitive information.
If you’re not sure whether this vulnerability affects your mobile device, you can look up your phone on a platform like GSMArena or your vendor’s website to see which SoC it uses, then cross-check it with MediaTek’s March security bulletin under CVE-2026-20435. You can log onto corp.mediatek.com/product-security-bulletin/March-2026 to review the list of affected chipsets and confirm whether your device may be at risk.
CyberGuy reached out to MediaTek for comment, but did not hear back before our deadline.

How to tell if your phone is affected
So how do you know if your phone is actually at risk? Not every Android phone is vulnerable. The issue primarily affects devices that use certain MediaTek processors. Here’s how to check your phone:
1) Find your phone model
Go to Settings > About phone and look for your exact model name.
2) Look up your processor (chip)
Search your phone model on a site like GSMArena or your manufacturer’s website to find the processor (also called the SoC).
3) Check if it uses MediaTek
If your phone uses a MediaTek chip, it may be affected. Devices with Qualcomm Snapdragon or Google Tensor chips are not part of this specific issue.
4) Install the latest security updates immediately
Check your phone’s system update settings and install any available updates from your manufacturer. Go to Settings > Software update and install any available updates. MediaTek has already released a fix, but phone makers must distribute it. Installing updates quickly ensures you receive the firmware patch if your device manufacturer has released it.
7 ways you can protect your phone from getting hacked
If your phone uses one of the affected chips, a few simple precautions can help reduce the chances of someone accessing your data if the device ever falls into the wrong hands.
1) Install strong antivirus protection
A security app cannot fix this processor-level flaw. However, it can still help protect your phone from other threats that often follow stolen or compromised devices. It will not stop this specific exploit, but it can detect malicious apps, spyware, and suspicious activity that attackers may install after gaining access. That extra layer of monitoring can help stop additional data theft if your device ever falls into the wrong hands.

2) Avoid keeping sensitive information on your phone
If you store things like cryptocurrency wallet seed phrases, recovery codes, or sensitive documents in notes apps or screenshots, consider moving them to a secure offline location. If someone extracts your phone’s data through this vulnerability, that information could be exposed.
3) Keep physical control of your phone
This exploit requires someone to physically connect your phone to a computer. Do not leave your device unattended in public places, and be cautious when handing it to repair shops or unknown technicians. Physical access dramatically increases the risk.
4) Use strong screen locks and auto-lock settings
While the vulnerability bypasses encryption on affected devices, strong lock settings still protect against many other threats. Use a longer PIN or passcode instead of simple patterns, and enable automatic locking after short periods of inactivity.
5) Protect accounts with two-factor authentication
Even if attackers gain access to data on your phone, two-factor authentication (2FA) can stop them from logging into your online accounts. Enable it for email, banking apps, cloud storage, and social media wherever possible.
6) Use a password manager
A password manager stores your login credentials in a secure, encrypted vault instead of leaving them scattered across apps and notes. If someone compromises your device, the password manager still protects your accounts with strong encryption, forcing attackers to break through another security layer before they can access your logins. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com
7) Enable USB restricted mode (if available)
Some Android devices limit USB data access when locked. Turning on this setting can reduce the risk of unauthorized data extraction through a wired connection, especially in situations where someone briefly gains physical access to your phone. On Samsung phones running the latest software:
Settings may vary slightly depending on your Samsung model and software version.
Go to Settings
Tap Lock screen
Then, tap Secure lock settings
Enter your current PIN, then tap Continue
Enable “Lock network and security” (or a similarly named option) to help block USB data access while your device is locked.

Kurt’s key takeaway
This vulnerability exposes a deeper issue with the Android ecosystem. Even when chipmakers release a fix, millions of phones depend on manufacturers to deliver updates that may never arrive, especially for cheaper devices that lose support quickly. We often assume our lock screen and encryption will protect our data if a phone is lost or stolen. However, incidents like this show that protection is only as strong as the update policies behind it. When devices stop receiving security patches, those protections quietly weaken over time.
Should phone manufacturers be required to guarantee security updates for several years if their devices contain critical encryption vulnerabilities? Let us know by writing to us at Cyberguy.com

Whether you’re considering starting a Sonos speaker setup, or adding to an existing group, the Sonos Era 100 is worth picking up. The compact, capable smart speaker is currently marked down to $189 ($30 off) at a variety of retailers, including Amazon, Best Buy, and directly from Sonos. If you want an even lower price, Sonos is selling refurbished Era 100 speakers for just $134. They come with fresh accessories and packaging, and sport the same one-year warranty as its new speakers.
The wireless speaker has a rich, detailed sound profile, with room-filling audio despite its small size. You might be able to improve the sound further with the Sonos Trueplay feature, which uses either your phone or the speaker’s built-in microphone to automatically tune it to your space. The Era 100 can easily connect with other speakers in the Sonos ecosystem for multi-room play, even with different Sonos models.
The Era 100 has expanded functionality from previous entry-level Sonos speakers, adding in Bluetooth and USB-C wired audio, as well as improved onboard controls. While the speaker features built-in voice assistant support for both Sonos and Alexa, you can flip a switch on its back to cut power to the microphone.

Carnival Corporation has confirmed a data breach affecting nearly 6 million people, and the fallout could reach travelers who may not think of themselves as Carnival customers.
The company says the incident involved a social engineering attack on a single user account. In other words, someone fooled an employee and gained access to part of Carnival’s IT system.
For cruise customers, the real concern starts after the breach. Stolen personal details can help scammers write messages that feel far more believable. Here is what may have been exposed, what Have I Been Pwned found in the leaked data and what you can do now to protect yourself.

MAJOR CRUISE LINE HACK EXPOSES SENSITIVE DATA OF NEARLY 6 MILLION TRAVELERS

What information was exposed in the Carnival breach?
Carnival Corporation says the breach began with a social engineering attack on a single user account. An unauthorized actor gained access to a limited part of the company’s IT system. Carnival says it immediately blocked the activity, brought in third-party security experts and alerted law enforcement.
A Carnival Corporation spokesperson told CyberGuy,
“In April, we identified unauthorized access to a limited part of our IT system caused by a social engineering attack on a single user account. We immediately blocked the activity, engaged third-party security experts and alerted law enforcement. Our investigation found certain personal information was illegally accessed. We’re notifying affected individuals and deeply regret any concern this causes. Protecting the privacy and security of personal data is a priority for us and we’ve added new layers of security and monitoring on top of the comprehensive protections already in place. We’ll also continue advancing our defenses against evolving threats.”
State breach reporting shows 5,995,277 people were affected. Carnival says the impacted data varies by individual. However, the company says the information known to be involved includes names, addresses, email addresses, phone numbers, dates of birth and government-issued identification numbers, such as driver’s license numbers and passport numbers.
What Have I Been Pwned found in the leaked Carnival data
Have I Been Pwned also analyzed the data published by ShinyHunters and said it contained 8.7 million records with 7.5 million unique email addresses. That data appeared tied to Holland America’s Mariner Society loyalty program and included names, dates of birth, email addresses, genders, geographic locations, salutations and loyalty program details.
That means this breach could affect you even if you think of yourself as a Holland America customer, not a Carnival customer. Even without a credit card number, this type of data can create problems. Criminals can use it to build fake emails, texts and calls that sound like they came from a real cruise brand. For example, a scammer could mention loyalty points, an upcoming trip, a refund or a cabin upgrade. That one familiar detail may be enough to get you to click.
What ShinyHunters claimed about Carnival
Carnival has not publicly confirmed that ShinyHunters carried out the attack. However, the extortion gang claimed responsibility in April 2026 and said it stole millions of records and internal corporate data.
ShinyHunters has also been tied to broader data theft and extortion activity involving Salesforce customers. The group often pressures companies by threatening to leak or sell stolen information.
The FBI has warned victims not to pay ransom demands from the group. Paying does not guarantee stolen data will be deleted. It also does not stop criminals from trying to extort victims again.
For you, the concern is what happens next. Once your data leaks, scammers may try to use it in emails, texts or calls that sound more believable than the usual junk.
Why the Carnival breach could put you at risk
Travel scams work because they catch you when you are excited, rushed or distracted. Maybe you booked a cruise years ago. Maybe you joined a loyalty program and forgot about it. Maybe you sailed with Holland America, Princess Cruises or another Carnival-owned brand. That old account can still have value to criminals.
Carnival has also dealt with several cybersecurity incidents before. The company disclosed breaches in March 2020 and June 2021 after attackers accessed employee email accounts. Ransomware incidents in August 2020 and December 2020 also exposed personal information tied to Carnival customers and employees.
That history does not mean every Carnival customer will face fraud. But it does show why old travel accounts deserve attention. A loyalty account can reveal more than points. It can connect your name, email, birthday, travel history and brand preferences.
That gives scammers more ways to sound convincing. A fake email may claim your loyalty points are expiring. A text may say you qualify for a refund. A caller may say your account needs verification. Those tricks can lead to stolen passwords, malware, fake payment pages or identity theft attempts.

Ways to stay safe after the Carnival breach
If you receive a Carnival breach notice, read it closely so you know what information may have been involved. Some impacted data may include government-issued identification numbers, so take these steps to lock down your accounts, spot fake cruise messages and reduce the chances that scammers can use your personal details against you.
1) Review Carnival’s offer for credit monitoring
Carnival says it is offering eligible U.S. individuals two years of complimentary credit monitoring. If you receive a notice, use the contact details in that notice or Carnival’s official breach webpage. Do not trust random links in emails, texts or search ads claiming to help you enroll.
2) Change your cruise account passwords
Go directly to the official website or app. Do not click a link from an email or text. Use a strong, unique password for every travel account. A password manager can help you create and store better passwords. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.
3) Turn on two-factor authentication
Two-factor authentication (2FA) adds another layer of protection. Even if someone steals your password, they still need a second approval. Use an authentication app when possible. Text codes help, but they can be weaker if a scammer tries a SIM swap attack.
4) Watch for fake cruise emails and texts
Be suspicious of messages about refunds, loyalty points, upgrades, cancellations or account verification. Scammers love urgent wording. They want you to click before you think. Instead, go straight to the company’s website or app. Check your account there.
5) Use a data removal service
A data removal service will not undo the Carnival breach. However, it can help remove your personal information from data broker and people-search sites. That can make it harder for scammers to combine leaked breach data with your home address, phone number, relatives’ names or other details found online. 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.
6) Use strong antivirus protection
Breaches often lead to phishing emails with dangerous links or attachments. Strong antivirus protection can help block malicious websites, scam pages and malware before they do damage. Also, keep your phone, tablet and computer updated. Security updates close holes that criminals try to exploit. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.
7) Do not share personal details with callers
If someone calls and claims to represent a cruise line, do not give out your date of birth, payment details or login codes. Hang up and call the company using a number from its official website.

8) Monitor your bank and credit card accounts
Check your statements for charges you do not recognize. Small test charges can show up before larger fraud attempts. Report suspicious activity right away. Many banks also let you lock a card from the app while you investigate.
9) Consider a credit freeze
A credit freeze can block criminals from opening new credit accounts in your name. You can freeze your credit for free with Equifax, Experian and TransUnion. You can also lift the freeze when you need to apply for credit.
10) Review your credit reports
Check your credit reports for accounts, addresses or inquiries you do not recognize. You can get free weekly credit reports from the three major credit bureaus at AnnualCreditReport.com.
11) Watch for misuse of your ID documents
Because Carnival says some impacted data may include driver’s license or passport numbers, be extra cautious with messages asking you to “verify” your identity. Do not upload a photo of your ID through a link in an email or text. Go directly to the official company, bank or government website instead.
12) Consider identity theft protection
Identity theft protection can help monitor your personal information, credit files and financial activity for warning signs of fraud. Some plans also include breach or dark web monitoring, which can alert you if your email address or other personal details appear in known leaks. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com
13) Save the breach notice
Keep a copy of any notice you receive from Carnival. It may explain what information was involved and what support the company offers. Be careful with fake settlement or claim websites. Scammers often create lookalike pages after major breaches.
Kurt’s key takeaways
The Carnival data breach shows why travel accounts need the same care as banking, shopping and email accounts. A cruise may last a week, but the data you shared can stick around for years. Take a few minutes now to tighten your accounts. Change reused passwords, watch for cruise-themed scams and consider freezing your credit if you want stronger protection.

Valve now says that the delayed Steam Machine PC and Steam Frame VR headset are set to launch sometime this summer. In a Thursday blog post detailing its Verified programs for both pieces of hardware, Valve concludes by saying that “We’re excited for players to try your titles on the new Steam hardware once they launch this summer.”
When the company originally announced the Machine and Frame alongside its new Steam Controller late last year, it said that it would start shipping the new gadgets in early 2026. But in February, the company announced that the ongoing memory and storage crunch had forced it to revisit its pricing and shipping plans. And in March, Valve said in a blog post that it would be “shipping all three products this year” — though that was after the company initially said in the post that “we hope to ship in 2026,” which it removed in an update.
Valve opted to release the Steam Controller on its own, putting it up for sale in early May. For the Machine and Frame, while “summer” isn’t exactly a specific date, it narrows the window for when the products might finally come out.
Ahead of actually launching the devices, Valve is redesigning the Steam store and sharing information about the Verified programs for the hardware so that developers can prepare their games. Like with the Steam Deck, if a game is verified for the Machine or the Frame, the badge signals that the game should work well without any tweaks from the user.
For the Machine, the requirements for a game to be verified are “nearly identical” to what they are for the Steam Deck. With the Machine being “roughly six times as powerful” as the Deck, in theory, many more games will be verified for it. Valve also says that it’s testing “every title on Machine that fell below our performance requirements on Deck.”
For the Frame, Valve’s verified badge will signify games that run well while being played natively on the headset — as opposed to games that work well streamed to the headset, which the Frame is also capable of. “Like Steam Deck Verified, the Steam Frame Standalone Verified program focuses on the experience customers will have with the device out-of-the-box in standalone mode,” Valve says.
Now, we just need Valve to share exactly when the Steam Machine and Steam Frame will be released and how much they might cost. After last week’s price hikes for the Steam Deck, I’m gearing up for sticker shock.
