Malicious Google Chrome extensions hijack accounts

NEWYou can now listen to Fox News articles!

Cybersecurity researchers have uncovered a serious threat hiding inside Google Chrome.

Several browser extensions pretend to be helpful tools. In reality, they quietly take over user accounts. These extensions impersonate popular human resources and business platforms such as Workday, NetSuite and SAP SuccessFactors. Once installed, they can steal login data and block security controls designed to protect users.

Many people who installed them had no warning signs that anything was wrong.

The fake Chrome extensions to watch out for

Security researchers from Socket’s Threat Research Team identified five malicious Chrome extensions connected to this campaign. The add-ons were marketed as productivity or security tools, but were designed to hijack accounts.

The extensions include:

DataByCloud Access
Tool Access 11
DataByCloud 1
DataByCloud 2
Software Access

We reached out to Google, and a spokesperson told CyberGuy that the extensions are no longer available on the Chrome Web Store. However, some are still available on third-party software download sites, which continues to pose a risk. If you see any of these names installed in your browser, remove them immediately.

Why malicious Chrome extensions look legitimate

These malicious add-ons are designed to look legitimate. They use professional names, polished dashboards and business-focused descriptions. Some claim to offer faster access to workplace tools. Others say they restrict user actions to protect company accounts. Privacy policies often promise that no personal data is collected. For people juggling daily work tasks or managing business accounts, the pitch sounds helpful rather than suspicious.

What these extensions actually do

After installation, the extensions operate silently in the background. They steal session cookies, which are small pieces of data that tell websites you are already logged in. When attackers get these cookies, they can access accounts without a password. At the same time, some extensions block access to security pages. Users may be unable to change passwords, disable accounts or review login history. One extension even allows criminals to insert stolen login sessions into another browser. That lets them sign in instantly as the victim.

Why malicious Chrome extensions are so dangerous

This attack goes beyond stealing credentials. It removes the ability to respond. Security teams may detect unusual activity, but cannot fix it through normal controls. Password changes fail. Account settings disappear. Two-factor authentication tools become unreachable. As a result, attackers can maintain access for long periods without being stopped.

How to check for these extensions on your computer

If you use Google Chrome, review your extensions now. The process only takes a few minutes.

Open Google Chrome
Click the three-dot menu in the top right corner
Select Extensions, then choose Manage Extensions
Review every extension listed

Look for unfamiliar names, especially those claiming to offer access to HR platforms or business tools.

How to remove suspicious Chrome extensions

If you find one of these extensions, remove it immediately.

Open Manage Extensions in Chrome
Find the suspicious extension
Click Remove
Confirm when prompted

Restart your browser after removal to ensure the extension is fully disabled. If Chrome sync is enabled, repeat these steps on all synced devices before turning sync back on.

What to do after removing the extension

Removal is only the first step. Change passwords for any accounts accessed while the extension was installed. Use a different browser or device if possible.

A password manager can help you create strong, unique passwords for each account and store them securely. This reduces the risk of reused passwords being exploited again.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

Finally, review account activity for unfamiliar logins, locations or devices and be sure to follow the steps below to stay safe moving forward.

Ways to stay safe going forward

Simple habits can significantly reduce your risk.

1) Limit browser extensions

Only install extensions you truly need. The fewer extensions you use, the smaller your attack surface becomes.

2) Be cautious with add-ons

Avoid extensions that promise premium access or special tools for enterprise platforms. Legitimate companies rarely require browser add-ons for account access.

3) Check permissions carefully

Be wary of extensions that request access to cookies, browsing data or account management. These permissions can be abused to hijack sessions.

4) Review extensions regularly

Check your browser every few months and remove tools you no longer use or recognize.

5) Use strong antivirus software

Strong antivirus software can help detect malicious extensions, block suspicious behavior and alert you to browser-based threats before damage occurs.

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.

6) Consider a data removal service

If your work or personal information has been exposed, a data removal service can help reduce your digital footprint by removing your details from data broker sites. This lowers the risk of follow-up scams or identity misuse.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

7) Avoid third-party download sites

Do not reinstall extensions from third-party websites, even if they claim to offer the same features. These sites often host outdated or malicious versions.

Kurt’s key takeaways

Browser extensions can be useful, but this research shows how easily they can also be abused. These fake Chrome add-ons did not rely on flashy tricks or obvious warnings. They blended in, looked professional and quietly did their damage in the background. The good news is that you do not need to be a tech expert to protect yourself. Taking a few minutes to review your extensions, remove anything unfamiliar and lock down your accounts can make a real difference. Small habits, repeated regularly, go a long way in reducing risk. If there is one takeaway here, it is this: convenience should never come at the cost of security. A clean browser and strong account protections give you back control.

A rogue AI led to a serious security incident at Meta

A rogue AI led to a serious security incident at Meta

For almost two hours last week, Meta employees had unauthorized access to company and user data thanks to an AI agent that gave an employee inaccurate technical advice, as previously reported by The Information. Meta spokesperson Tracy Clayton said in a statement to The Verge that “no user data was mishandled” during the incident.

A Meta engineer was using an internal AI agent, which Clayton described as “similar in nature to OpenClaw within a secure development environment,” to analyze a technical question another employee posted on an internal company forum. But the agent also independently publicly replied to the question after analyzing it, without getting approval first. The reply was only meant to be shown to the employee who requested it, not posted publicly.

An employee then acted on the AI’s advice, which “provided inaccurate information” that led to a “SEV1” level security incident, the second-highest severity rating Meta uses. The incident temporarily allowed employees to access sensitive data they were not authorized to view, but the issue has since been resolved.

According to Clayton, the AI agent involved didn’t take any technical action itself, beyond posting inaccurate technical advice, something a human could have also done. A human, however, might have done further testing and made a more complete judgment call before sharing the information — and it’s not clear whether the employee who originally prompted the answer planned to post it publicly.

“The employee interacting with the system was fully aware that they were communicating with an automated bot. This was indicated by a disclaimer noted in the footer and by the employee’s own reply on that thread,” Clayton commented to The Verge. “The agent took no action aside from providing a response to a question. Had the engineer that acted on that known better, or did other checks, this would have been avoided.”

Last month, an AI agent from open source platform OpenClaw went more directly rogue at Meta when an employee asked it to sort through emails in her inbox, deleting emails without permission. The whole idea behind agents like OpenClaw is that they can take action on their own, but like any other AI model, they don’t always interpret prompts and instructions correctly or give accurate responses, a fact Meta employees have now discovered twice.

Phishing scam exploits Apple Mail ‘trusted sender’ label

Phishing scam exploits Apple Mail ‘trusted sender’ label

NEWYou can now listen to Fox News articles!

Phishing emails are getting more convincing every day. Scammers copy the look of trusted brands and rely on urgency to get you to click before you think. But sometimes the most misleading part of a scam is not the email itself. It is the signal your own email app gives you.

A CyberGuy reader recently sent us a screenshot of an email that looked suspicious but included something surprising at the top. Apple Mail displayed a banner that said, “This message was sent from a trusted sender.” At first glance, that message feels reassuring. Many people would assume the email must be legitimate. The reader sent the screenshot with the subject line “Another sneaky trick.” In the image, Apple Mail labels the message as coming from a trusted sender even though the email itself shows several signs of a phishing scam.

Here is the catch. That label comes from Apple Mail itself, not from Apple and not from a system verifying the email. In other words, a phishing email can still appear trusted. Understanding how this happens can help you avoid handing your Apple ID or other personal information to scammers.

Why Apple Mail may label a phishing email as a trusted sender

Apple Mail automatically adds the trusted sender banner in certain situations. It usually appears when the email address looks familiar to your device. For example, Apple Mail may display the banner if:

The sender’s address is saved in your Contacts
You have replied to that email address before
The address appears in previous email conversations

The feature is designed to help you quickly recognize people you communicate with often. It is meant as a convenience signal, not a security verification. That distinction is important.

Warning signs of a fake Apple account email

Phishing emails often copy the look of real Apple notifications. The goal is to create urgency so the victim clicks before thinking. The email in the screenshot contains several classic warning signs.

Generic greeting

The message begins with “Dear user” instead of addressing the recipient by name. Legitimate account emails typically reference your name or Apple ID information.

Slightly incorrect branding

The email references “Cloud+ subscription.” Apple’s real service is called iCloud+. Small branding mistakes often appear in phishing campaigns.

Urgent scare tactics

The message warns that personal data could be permanently removed from cloud storage. Fear and urgency are common tools in phishing scams.

Payment problems tied to account threats

Scammers often claim a subscription payment failed and your account is at risk. The goal is to push victims to click a link and enter login details. Apple does not send emails threatening immediate deletion of iCloud data because of a billing issue.

Why the Apple Mail trusted sender banner can be misleading

Because the banner relies on familiarity, scammers can sometimes exploit it. Cybercriminals often spoof real email addresses so their messages appear to come from someone you know. If that address matches a contact or previous message history, Apple Mail may still mark it as trusted.

REAL APPLE SUPPORT EMAILS USED IN NEW PHISHING SCAM

That can create a false sense of safety. The banner simply reflects your email history. It does not confirm the sender’s identity or verify that the message actually came from Apple or any legitimate company. In some cases, that visual signal can make a phishing email look more believable than it really is.

Ways to stay safe from Apple phishing emails

Phishing emails continue to evolve, but a few simple habits can greatly reduce your risk.

1) Avoid clicking links in account warning emails

If you receive a notice about your Apple account, open your browser and go directly to Apple’s official website instead of using the email link.

2) Use strong antivirus software

Strong antivirus software can help detect malicious links, suspicious downloads, and phishing pages before they reach your device. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com

3) Use a data removal service

Scammers often gather personal information from data broker websites to make phishing emails look more convincing. Removing your data from these sites reduces the information criminals can use to target you. 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.

4) Check your Apple account settings directly

You can verify subscriptions by opening Settings on your device, tapping your Apple ID and selecting Subscriptions.

5) Look closely at branding and wording

Misspelled product names, unusual formatting, and generic greetings often reveal a phishing email.

6) Enable two-factor authentication

Two-factor authentication (2FA) adds another layer of protection, even if someone manages to steal your password.

Kurt’s key takeaways

Email apps often try to help by identifying messages that appear familiar. Unfortunately, scammers understand how those systems work. The trusted sender banner in Apple Mail reflects your contact history. It does not confirm that the message came from Apple or any legitimate company. That means one simple habit still offers the best protection. Pause before clicking any urgent account warning. Because in the world of phishing scams, the messages that look the most convincing are often the most dangerous.

If your email app told you a message was trusted, would you still double-check before clicking? Let us know by writing to us at Cyberguy.com.
