These malicious files can be used in various types of attacks, including phishing schemes and zero-click exploits, making them a straightforward way for attackers to gain access to a victim&#8217;s system.<\/p>\n<p>The following are the top three Microsoft Office-based exploits that are still prevalent this year, along with the necessary information to help you avoid them.<\/p>\n<h2 style=\"text-align: left;\">1. Phishing in MS Office: A Persistent Threat<\/h2>\n<p>Phishing attacks that utilize Microsoft Office files have been around for years and continue to be a significant threat. The reason for their persistence is simple: they are effective, especially in business environments where teams frequently exchange Word and Excel documents.<\/p>\n<p>Attackers are aware that people are accustomed to opening Office files, particularly if they appear to come from a colleague, client, or partner. A fake invoice, a shared report, or a job offer can be enough to convince someone to click on a malicious link. Once the file is opened, the attacker has the opportunity to carry out their malicious intentions.<\/p>\n<p>Phishing attacks using Office files often aim to steal login credentials and may include:<\/p>\n<ul>\n<li>Links to fake Microsoft 365 login pages<\/li>\n<li>Phishing portals that mimic company tools or services<\/li>\n<li>Redirect chains that ultimately lead to credential-harvesting sites<\/li>\n<\/ul>\n<p>In this ANY.RUN malware analysis session, an Excel file contains a malicious phishing link:<\/p>\n<p><a href=\"https:\/\/app.any.run\/tasks\/e6f0d858-d525-461e-acda-32c51e13e2e7?utm_source=thehackernews&amp;utm_medium=article&amp;utm_campaign=top3_msoffice_exploits&amp;utm_content=task&amp;utm_term=270325\" rel=\"noopener nofollow\" target=\"_blank\">View analysis session with Excel file<\/a><\/p>\n<table cellpadding=\"0\" cellspacing=\"0\" class=\"tr-caption-container\" style=\"float: left;\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\">\n<a href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEjBL7vE1Rt3vLT2Nr8W-x53yDy9yMYKAK8No5NxmHZM3VgdWZT8YCsnuoDIeJBpTe-ISSUu8vr4TJM3bAkIWp90xo2supKmNMSAhdO6M7aT06aVvO7BvkRm7s0avO1O0F9bMCXnV0i1jBNbJZGUt7SrXU7Znd2MdPcHcwuvI2Rv08ORglAQyunBZm7uFwRc\/s1800\/1.png\" style=\"clear: left; display: block; margin-left: auto; margin-right: auto;  text-align: center;\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEjBL7vE1Rt3vLT2Nr8W-x53yDy9yMYKAK8No5NxmHZM3VgdWZT8YCsnuoDIeJBpTe-ISSUu8vr4TJM3bAkIWp90xo2supKmNMSAhdO6M7aT06aVvO7BvkRm7s0avO1O0F9bMCXnV0i1jBNbJZGUt7SrXU7Znd2MdPcHcwuvI2Rv08ORglAQyunBZm7uFwRc\/s1800\/1.png\" alt=\"\" border=\"0\" data-original-height=\"911\" data-original-width=\"1600\"\/><br \/>\n<\/a>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"tr-caption\" style=\"text-align: center;\">Excel file containing malicious link detected inside ANY.RUN sandbox<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>When clicked, the victim is redirected to a webpage that displays a Cloudflare &#8220;Verify you&#8217;re a human&#8221; check.<\/p>\n<table cellpadding=\"0\" cellspacing=\"0\" class=\"tr-caption-container\" style=\"float: left;\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\">\n<a href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEikH31lxosKj6ODvNLNdiQfIfjaSPJRXWWk8r6EakUrNBj-lhU8hcNaxwXtJiHZQDP8klLsbRvCPjfzqoKiqST8r_iynciPqBSPV362moDvkeZg4Hztbh0cbOPtJTw5WyRMtfibHuiewOJpQCJKL4a5CciHcHJD54-tDHi12P_WNJPkPOzTqH3iRI8T1HwR\/s1800\/2.png\" style=\"clear: left; display: block; margin-left: auto; margin-right: auto;  text-align: center;\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEikH31lxosKj6ODvNLNdiQfIfjaSPJRXWWk8r6EakUrNBj-lhU8hcNaxwXtJiHZQDP8klLsbRvCPjfzqoKiqST8r_iynciPqBSPV362moDvkeZg4Hztbh0cbOPtJTw5WyRMtfibHuiewOJpQCJKL4a5CciHcHJD54-tDHi12P_WNJPkPOzTqH3iRI8T1HwR\/s1800\/2.png\" alt=\"\" border=\"0\" data-original-height=\"901\" data-original-width=\"1600\"\/><br \/>\n<\/a>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"tr-caption\" style=\"text-align: center;\">CloudFlare verification passed with ANY.RUN&#8217;s automated interactivity<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>After clicking through, there&#8217;s another redirect; this time to a fake Microsoft login page.<\/p>\n<table cellpadding=\"0\" cellspacing=\"0\" class=\"tr-caption-container\" style=\"float: left;\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\">\n<a href=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEgG-LSOFq8yOZwlRzf-jKIdduzu5EoBTOFWKbneGk4pFBcWm-WKyuGbWWQVAzMM4kJRf5OaYV4O3kv2l5nKrjV2030wCpMSr3z5Xl44qn0EukMPLlsXnPeXDjg-zWiQqx3KF9phSjwnULfqmB_ATqha8rEjg9onM0L1QUZSplSdJTsVE4R46LYNyvmAmIQs\/s1800\/3.png\" style=\"clear: left; display: block; margin-left: auto; margin-right: auto;  text-align: center;\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEgG-LSOFq8yOZwlRzf-jKIdduzu5EoBTOFWKbneGk4pFBcWm-WKyuGbWWQVAzMM4kJRf5OaYV4O3kv2l5nKrjV2030wCpMSr3z5Xl44qn0EukMPLlsXnPeXDjg-zWiQqx3KF9phSjwnULfqmB_ATqha8rEjg9onM0L1QUZSplSdJTsVE4R46LYNyvmAmIQs\/s1800\/3.png\" alt=\"\" border=\"0\" data-original-height=\"852\" data-original-width=\"1600\"\/><br \/>\n<\/a>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"tr-caption\" style=\"text-align: center;\">Malicious link to fake Microsoft login page with random characters<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>At first glance, it may seem legitimate.

CVE-2017-11882: The Equation Editor Exploit That Refuses to Die<\/h2>\n<p>First discovered in 2017, CVE-2017-11882 is still being exploited today, primarily in environments running outdated versions of Microsoft Office.<\/p>\n<p>This vulnerability targets the Microsoft Equation Editor, a rarely used component that was part of older Office builds. Exploiting it is relatively simple: just opening a malicious Word file can trigger the exploit. No macros or extra clicks are needed.<\/p>\n<p>In this case, the attacker uses the flaw to download and run a malware payload in the background, often through a remote server connection.<\/p>\n<p>In our analysis session, the payload delivered was Agent Tesla, a known info-stealer used to capture keystrokes, credentials<br \/>\n<br \/>\n<br \/><a href=\"https:\/\/thehackernews.com\/2025\/03\/top-3-ms-office-exploits-hackers-use-in.html\" rel=\"nofollow noopener\" target=\"_blank\">Source Link<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cyber attackers have been utilizing Word and Excel documents as a means to deliver malware for a long time, and this tactic remains effective even in 2025.
