Major 3 MS Office Exploits Hackers Use in 2025 – Be Alert!

In 2025, hackers have long used Word and Excel files as malicious shipping methods. Malicious Office documents are still one of the simplest ways to get into a murderer’s system, from zero-click exploits to phishing schemes.

What you need to know about the best three Microsoft Office-based scams that are still popular this year and how to avoid them.

1. Also popular among hackers in MS Office is Phishing.

Phishing problems using Microsoft Office files have been around for ages, and they continue to be successful. Why? Because they function, especially in business settings where groups exchange Word and Excel files frequently.

Attackers are aware that people are already familiar with opening Office files, especially if they are from someone who appears to be a spouse, client, or coworker. It doesn’t take much to persuade people to click through a false receipt, shared report, or job offer. The perpetrator has a chance once the document is available.

Phishing with Office records frequently aims to spoof login information. These records may include:

• Links to phony Microsoft 365 registration pages
• websites that imitate business products or services
• Switch bars that ultimately end up on credential-harvesting websites

In this No. An Excel file with malignant hacking links has been analyzed by RUN ransomware analysis session:

The sufferer is taken to a website that displays a Cloudflare” Check you’re a people” examine when they click.

After clicking over, there is yet another transfer, this day to a false Microsoft login page.

It might appear to be true at first glance. however, inside the ANY. Red colors are easily discernable in the RUN platform. The login URL for Microsoft isn’t official; it’s full of unintended characters and obviously doesn’t belong in Microsoft’s hands.

Give your team the tools they need to quickly identify, research, and record threats in a safe environment.

Get a test of ANY. RUN to gain access to sophisticated trojan study

The sufferer unintentionally provides the intruder with their login information on this false login page.

Intruders are even developing their imagination. Recently, QR codes have been embedded in some hacking files. These are meant to be scanned with a cellphone, causing the sufferer to visit a phishing site or triggering a trojan access. But, they can be identified and analyzed using equipment like ANY. Move the Sandbox as well.

2. CVE-2017-11882: The Equation Editor Exploit ThatWon’t Die

CVE-2017-11882 was first discovered in 2017, and it is still being exploited in today’s Microsoft Office-related situations.

The Microsoft Equation Editor, a seldom used element that was included in older Office versions, is the target of this vulnerability. It is extremely simple to exploit it: simply opening a malicious Word file can cause the exploit to work. No scripts or additional taps required.

In this situation, the perpetrator uses the weakness to get and execute a ransomware payload in the background, frequently via a remote server connection.

The cargo for our evaluation session was Agent Tesla, a well-known info-stealer used to record keys, credentials, and clipboard data.

We can see how ANY in the MITRE ATT&amp, CK part of this study. This particular tactic was used in the attack by Run sandbox:

Although Microsoft patched the risk years before, it’s still important for hackers to use it to hack systems that haven’t received updates. CVE-2017-11882 has also become a backup for cybercriminals who want guaranteed implementation because older Office versions have scripts disabled by default.

3. CVE-2022-30190: Follina’s Still in the Game

For one simple reason, the Follina exploit ( CVE-2022-30190 ) is still popular with attackers: it doesn’t require any user interaction beyond opening a Word file. It works without macros.

Follina uses special URLs embedded in Office documents and the Microsoft Support Diagnostic Tool ( MSDT ) to execute remote code. That means that malicious code that are frequently Power Shell-based can be launched from a command-and-control site simply by viewing the report.

The strike went a step further in our sample for malicious analysis. The” stegocampaign” tag, which we observed, demonstrates the use of steganography, a method by which malicious code is hidden inside image files.

PowerShell uses the image to download and process it, extracting the true cargo without making any alarms right away.

Follina is frequently used in multi-stage attack bars, combining different flaws or cargo to increase the impact, to make matters worse.

What Does This Mean for Teams Using Microsoft Office?

The problems mentioned above may serve as a wake-up call if your crew relies heavily on Microsoft Office for day-to-day tasks.

Scammers are aware of the widespread use and reliability of Office records in business. That’s why they continue to take advantage of them. These files can cause serious risks to the safety of your organization, whether it’s a straightforward Excel sheet with a hacking hyperlink or a Word document that is discreetly executing malicious code.

What does your team do, please?

• To enable quick response from your security staff, be informed about new exploit techniques involving Office types.
