Hackers have long used Word and Excel documents as delivery vehicles for malware, and in 2025, these tricks are far from outdated. From phishing schemes to zero-click exploits, malicious Office files are still one of the easiest ways into a victim’s system. Here are the top three Microsoft Office-based exploits still making the rounds this year and what you need to know to avoid them. 1. Phishing in MS Office: Still Hackers' Favorite Phishing attacks using Microsoft Office files have been around for years, and they're still going strong. Why? Because they work, especially in business environments where teams constantly exchange Word and Excel documents. Attackers know that people are used to opening Office files, especially if they come from what looks like a colleague, a client, or a partner. A fake invoice, a shared report, or a job offer: it doesn't take much to convince someone to click. And once the file is open, the attacker has their chance. Phishing with Offic...
