It meant that, even if an attacker possessed the account credentials, they couldn&#8217;t log in without the second factor. While that logic was sound, attackers have now figured out that they don&#8217;t need to steal the second factor: they just need the user to hand it over.<\/p>\n<p>If your workforce authenticates with push-based MFA, this attack is a live threat to your organization today. Tools like Specops Secure Access are built specifically to close that gap, but before getting into the fix, it&#8217;s worth understanding how this technique works.<\/p>\n<h2>How MFA prompt bombing works<\/h2>\n<p>The attack requires three key elements to work:<\/p>\n<ul>\n<li>Valid account credentials, usually sourced from breached password dumps on the dark web<\/li>\n<li>A login portal that uses push-based MFA (such as a VPN, Microsoft 365, Okta, or Duo)<\/li>\n<li>A victim who is alerted every time the attacker tries the login<\/li>\n<\/ul>\n<p>Attackers repeatedly trigger the prompt, attempting to trick the target or wear them down to approve the request. Sometimes, attackers will pair prompt bombing with a vishing call pretending to be from IT, where they will try to socially engineer the target. The danger is that these methods only need to work once.<\/p>\n<p>If the prompt is approved, the attacker is logged in as that user. Security systems typically won&#8217;t be alerted, as the login looks entirely legitimate.<\/p>\n<h2>The Cisco breach<\/h2>\n<p>The 2022 Cisco breach is a key example of how effective this technique is against even mature security programs. An attacker linked to the Yanluowang ransomware group compromised a Cisco employee&#8217;s personal Google account, which was syncing browser-stored credentials, including the employee&#8217;s Cisco VPN password.<\/p>\n<p>From there, the attacker pushed MFA prompts to the employee&#8217;s phone. That initially didn&#8217;t work, so they began using vishing calls posing as trusted support organizations, speaking in various accents, and eventually convincing the&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/05\/mfa-prompt-bombing-why-your-second.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>MFA Prompt Bombing: Why Your Second Factor Isn&#8217;t Saving You https:\/\/thehackernews.com\/2026\/05\/mfa-prompt-bombing-why-your-second.html Publish Date: 2026-05-26 06:30:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":255711,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEgtums9LZoPXx5AzbNIYmdrNPI6vAAWAnYGfW6NzZ4DkICva0wX2GjMPvmYoq4EVuhvWUc6FyLrgJJ0Hvh8w0TBJ4MLkQplbffUwg89oiQxoJhV-93mboD0D2rdkrrhsblZ2tLJv-auc2GBNjIMsg8wGUCYOkZHNDHaQoqhDbLXrFC3-rD3cz0pI12U7rR2\/s1600\/prompt-1.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[30],"class_list":["post-255710","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-breach"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/255710"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=255710"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/255710\/revisions"}],"predecessor-version":[{"id":255712,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/255710\/revisions\/255712"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/255711"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=255710"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=255710"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=255710"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
