The Return of Follina: How to Defend Against This Zero-Day

The Follina zero-day vulnerability is back, allowing hackers to install malware on your system just by previewing a malicious Word document. Here's how to protect yourself:

Turn off the Windows Support Diagnostic Tool (MSDT) protocol, which is how Follina infiltrates systems. Open the Run dialog box (Windows key + R), type “regedit”, and navigate to

HKEY_CLASSES_ROOT\ms-msdt. Right-click ms-msdt and select Delete.

Be extremely wary of unsolicited Word docs and disable the preview pane. Only open attachments from trusted senders. If a doc looks suspicious, delete it immediately.

Keep Windows and Office fully updated. The latest patches address many vulnerabilities that hackers exploit. Enable automatic updates if you haven’t already.

Use a reputable antivirus program and scan your system regularly. An antivirus can detect and remove malware, including anything installed via Follina. Perform regular system scans, at least once a week.

Exercise caution when clicking links and downloading software. Only download from verified, official sources. Watch out for phishing emails and malicious websites aiming to infect systems with malware.

Backup important files in case of infection. With regular backups to an external drive or cloud storage, you can recover your files even if malware damages them.

Staying vigilant and taking proactive precautions are the best ways to avoid becoming a victim of Follina or other cyberthreats looming in 2023. While hackers are working hard to find new ways into systems, with the right safeguards in place you can rest assured your data and privacy are protected. Take control of your cybersecurity now so you're not caught off guard later.

Proxy Shell Attacks: Detecting and Blocking Remote Code Execution

Proxy shell attacks are on the rise, allowing hackers remote access to sensitive data and systems. These attacks exploit vulnerabilities in web servers and apps to execute malicious code remotely.

To detect proxy shell attacks, monitor your web servers and apps for unusual activity or changes. Look for suspicious files, connections from unknown IP addresses, or spikes in bandwidth or CPU usage. Another sign is website defacement or redirects to malicious sites.

To block proxy shell attacks, keep all web software up to date with the latest security patches. This includes your operating systems, web servers, CMSs, plugins, and themes. Strong passwords, two-factor authentication, and limiting admin access can also help reduce vulnerability.

Restricting web shell uploads and enforcing a whitelist for permitted file types and extensions prevents hackers from uploading malicious scripts. You should also disable PHP in uploaded files and block execution of uploads in wp-content/uploads. Regularly scan your website for vulnerabilities and malware.

For added protection, use a web application firewall (WAF) to monitor and block suspicious traffic. A WAF can detect common web attacks like SQL injections, cross-site scripting, and remote code execution, effectively shielding your site from proxy shell attacks and other threats.

By staying on top of the latest cyberthreats, hardening your systems, monitoring diligently, and using a WAF, you can defend against proxy shell attacks and avoid becoming another statistic. The risks are real, but with vigilance and the right safeguards, your website and data can remain secure.

The Barracuda Backdoor: Why This APT Is Gaining Traction

The Barracuda backdoor is an emerging threat you need to be aware of. This malware, believed to be developed by a Chinese advanced persistent threat (APT) group, allows hackers to gain access to your network without authorization. Once inside, they can spy on your activities, steal data, deploy ransomware, and cause other damage.

Barracuda works by exploiting vulnerabilities in network security to sneak in the backdoor. The hackers then use this foothold to explore further, moving laterally through the network to find their real targets. They search for vulnerabilities like poorly configured servers, unpatched software, and weak passwords to gain admin access.

Some signs your network may be compromised by Barracuda include:

• Strange connections or logins at odd hours from unfamiliar IP addresses.
• Increased network activity or bandwidth usage with no obvious cause.
• Antivirus or firewall alerts for malicious behavior.
• Websites or services suddenly becoming inaccessible.

To defend against Barracuda and similar backdoors, take these actions:

Patch and update everything.

Run regular scans to find vulnerabilities and software needing updates. Patch them immediately. Out-of-date systems are a hacker’s best friend.

Use strong, unique passwords.

Require complex passwords, two-factor authentication where possible, and never reuse the same password across sites or services.

Monitor for anomalies.

Keep a close eye on logs, traffic, and user behavior for anything unusual. The sooner you detect intrusion, the less damage can be done.

Restrict access and permissions.

Only provide users the minimum access needed to do their jobs. This limits how much damage can be done if an account is compromised.

Provide security awareness training.

Educate your staff on the latest phishing techniques, malware, and social engineering methods used by hackers. Human error is still a leading cause of breaches.

With vigilance and the right safeguards in place, you can help ensure Barracuda and other backdoors don’t find their way into your network. Staying up-to-date with the latest cyberthreats and how to thwart them is key to keeping your systems and data secure.

FAQ: Answers to Your Pressing Cybersecurity Questions

With cybercrime on the rise, you probably have questions about how to protect yourself online. Here are some of the most frequently asked cybersecurity questions and answers to help put you at ease.

What are the biggest cyberthreats I need to watch out for?

Some of the top vulnerabilities to be aware of in 2023 include:

• Phishing attacks: Fraudulent emails or texts trying to trick you into providing sensitive data or downloading malware. Never click links or download attachments from unsolicited messages.
• Ransomware: Malicious software that locks you out of your files or computer until you pay a ransom. Back up your files regularly in case of infection.
• IoT device hacks: Hackers can gain access to your home network by compromising smart home gadgets like security cameras or routers. Change the default passwords on all internet-connected devices.
• Supply chain attacks: Hackers insert malware into software updates for popular programs and services. Only download updates from verified, trusted sources.

How can I strengthen my online security?

Some of the best ways to improve your cyber defenses include:

• Use strong, unique passwords for all accounts and enable two-factor authentication whenever available.
• Be cautious of public Wi-Fi networks. Avoid conducting sensitive activities like online banking or shopping on unsecured networks.
• Keep all software up to date with the latest patches to prevent vulnerabilities. This includes operating systems, browsers, plugins, and mobile apps.
• Use antivirus software and be wary of suspicious links, downloads, and attachments which could contain malware.
• Never share sensitive personal or account information with unsolicited callers, texters or emailers. Legitimate companies will not ask for passwords, social security numbers or bank account access.
• Educate yourself on the latest online threats and how to spot them. Staying vigilant is one of the best ways to avoid becoming a cybercrime victim.
