Patched Microsoft Outlook Vulnerability

Microsoft recently fixed a serious security flaw in Outlook that scored a 9.8 on the Common Vulnerability Scoring System.

This flaw, CVE-2023-2339, is a zero-click vulnerability. It could let hackers steal sensitive information from user accounts and send malicious emails as if they were the user.

The CVE-2023-2339 flaw affects all supported Windows Outlook versions. However, Outlook on the web, Android, iOS, Mac, and Microsoft 365 services are unaffected.

How the Security Flaw Works

The flaw comes from a Microsoft Outlook feature that allows users to customize their
notification sounds. The problem is that the audio file is on a remote server.

Cybercriminals can send malicious emails posing as calendar invites. The victim’s computer then loads the notification sound from a server controlled by the threat actor.

This can expose login credentials, which the hacker can use for unauthorized access.

The victim doesn’t even have to do anything for this to happen. When Outlook gets the
malicious email, it automatically starts the process remotely.

Protecting Your Business

The first step is to install the latest security update for Microsoft Outlook. For now, you should also limit using the New Technology LAN Manager (NTLM).

Companies can also block outbound SMB traffic over port 445. This will help prevent
unauthorized access.

Microsoft has also released an audit tool to help businesses determine if there was a breach.

Actionable Steps for Business Owners

To protect your business and customers from this Microsoft Outlook security flaw, consider these proactive steps:

1. Educate staff about the importance of security updates.
2. Keep Microsoft Outlook installations updated with the latest patches.
3. Monitor network traffic and block unauthorized connections.
4. Encourage strong, unique passwords and install multi-factor authentication (MFA).
5. Regularly review and update cybersecurity policies and practices.

These strategies help address potential cyber threats and keep your business data secure.

Cybercriminals can use the weakness in Microsoft Outlook to steal sensitive information and pose as users. This is a big risk for businesses.

Owners must act quickly to secure their systems and protect their customers. Use the steps above to avoid potential threats and keep your computer system safe.

How Cybercriminals are Exploiting the Silicon Valley Bank Shutdown

Recently, there was a rise in cybercrimes related to the closing of Silicon Valley Bank (SVB). Threat actors go after businesses and sometimes use them in their illegal activities.

SVB was the 16th largest bank in the U.S. The bank worked with tech giants like Buzzfeed, Roblox, and Roku. However, global inflation and a deposit run caused regulators to close the bank on Friday, March 10, 2023.

Hackers are using SVB-related content to manipulate people’s emotions. Analysts are finding more phishing attacks connected to the SVB closure, and new threats appear daily.

How Hackers Set Up SVB-related Attacks

Cybercriminals started buying fake SVB domains shortly after SVB closed. This is how they set up their SVB-related attacks. The attackers then made and tested phishing flows before starting their campaigns.

More than 62 new domains were set up for SVB-related attacks, and there were 200 phishing scams, most of which targeted businesses in the U.S.

The Public Response Helped Hackers

Unfortunately, the public’s response to the SVB crisis may have been unwittingly aiding cybercriminals. Attackers used websites that listed affected SVB customers to find targets.

Also, emails from companies switching to new banks can look like phishing emails, which can cause confusion and make the risks higher.

Getting Ready for the Wave of SVB Fraud

To counter SVB-related attacks and protect your business, you should:

1. Raise employee awareness about phishing and cyber threats.
2. Provide regular security training.
3. Implement email security solutions with anti-phishing features.
4. Use multi-factor authentication.
5. Keep software updated to prevent vulnerabilities.
6. Encourage strong, unique passwords and start using password managers.
7. Monitor the company’s online presence for fake domains or websites.
8. Develop and maintain an incident response plan.
9. Periodically review and update security processes.
10. Collaborate with cybersecurity experts for audits and vulnerability assessments.

The recent failure of SVB has given cybercriminals a chance to take advantage of businesses and individuals. To protect yourself from SVB-related attacks and other cyber threats, you need to put cybersecurity at the top of your list of priorities.

You can shield your company from these attacks by being proactive, improving security infrastructure, and using your resources wisely.

Firefox 111 Boosts Security, Fixes Bugs, and Adds New Features

Mozilla has released a new version of Firefox for Android, equipping it with a built-in PDF viewer. Firefox 111 also provides a more secure experience for users through its Total Cookie Protection feature. In addition, the upgrade addresses the security issues and unusual bugs in the last version.

Android Users Finally Have Total Cookie Protection on Firefox

In 2021, Mozilla launched Total Cookie Protection for incognito Windows. It was an optional feature that users could turn on. In 2022, the company rolled it out to all Mac and Windows users. It enabled the security feature by default for all Windows. A year later, Mozilla finally debuted it for Android users.

Total Cookie Protection acts as a “cookie jar” for each website you visit. It contains cookies within their respective sites to prevent cross-site tracking. It is an extra layer of protection for your online data. It also gives you a break from intrusive ads, deterring companies from gathering information about you.

Mozilla Releases Additional Features for Android Users

Another highlight of the new Firefox 111 is its built-in PDF viewer. It eliminates the need for third-party apps when viewing PDF documents on your Android phone. There is also an exclusive feature for Pixel phone users with Android 12 or 13. You can now share links to recently viewed pages from the recent screen.

Aside from these new features, Firefox 111 has bug fixes for Android. It resolves the compatibility issue with Android 13 that was causing problems with copying saved passwords. Mozilla has also fixed the crashing that users were experiencing with the media playback notification.

Firefox 111 Has Browser Improvements for macOS and PC

Android users aren’t the only ones to benefit from the Firefox 111 upgrades. Mozilla has also addressed Windows 11 and macOS issues. It fixed the bug that was causing Firefox to freeze during start-up. It also resolved the issue that made Firefox crash when users pinch-zoomed.

Update to Minimize Your Risks 

No matter what browser you use in the office, encourage all your team members to upgrade to the latest version. Outdated versions are open to more security vulnerabilities. Once your browser is compromised, threat actors can steal sensitive information and install malware. Aside from improving security, upgrading your browser will also speed up the browsing experience and boost your team’s efficiency.

Protect Your Business from the Latest Emotet Phishing Scam Targeting Taxpayers

Scammers will use anything to target businesses, including tax forms. A new phishing campaign is spreading a malicious program disguised as documents from the IRS. With the tax season in full swing soon, business owners must take extra precautions to protect sensitive company data.

Emotet Phishing Campaign Targets Taxpayers

Emotet is one of the most widespread malware programs in recent years. The latest emotet phishing campaign targets taxpayers. It impersonates the IRS and other private organizations, sending emails containing phony Form W-9 attachments.

When someone falls for the scam and installs the emotet on their computer, the malware will steal data and take control of their email. It will send spam emails using the target’s account to spread other malicious programs.

Obvious Emotet Phishing Signs to Look Out For

The Emotet phishing emails may seem legitimate, but some telltale signs give them away. The malicious emails have an attached Zip file. It contains a Word document that is supposedly the Form W-9. But you can tell it is fake because it is over 500 megabytes. No ordinary Word document is ever that big.

In addition, Microsoft has disabled macros from operating on the system. A security warning will appear when a user tries to open a malicious Word document, saying it contains blocked macros. That is the ultimate warning sign of a phishing scam, so don’t enable the content.

Emotet is trying to circumvent Microsoft’s solution by sending OneNote files instead. When a user opens the attachment, it will say the document is protected and that they must click the “View” button. Once they do, it will cause the embedded VBScript to run. OneNote will display a warning about the potentially malicious script, but inattentive users will launch it anyway.

It is essential to note that legitimate tax documents are usually in PDF form. Be cautious about opening Word, OneNote, and other file types from dubious sources.

How to Minimize Your Risks 

The Emotet phishing campaign can have disastrous outcomes for companies. But you can minimize risk by knowing the warning signs. The same goes for other malicious schemes. If business owners and employees learn about these techniques, they can prevent data loss and stop the spread of malware.
