Common questions
Is BlueHammer related to the “BlueHammer” Windows Defender vulnerability?
No. In April 2026 security researchers used the name “BlueHammer” for a privilege-escalation flaw in Microsoft Defender (CVE-2026-33825), which Microsoft patched that month. News coverage calls it the BlueHammer vulnerability or BlueHammer exploit. The flaw is in Microsoft's software. It shares only the name with BlueHammer apps and has no connection to them or to the companies listed on this page.
Is the BlueHammer Security app safe?
Yes — it's a genuine app from a registered company, published on the App Store by Blue Hammer PTE LTD (UEN 202449996N) and listed on Google Play, where it passed each store's review. Install it only from the links on this page; what it collects and why is set out in our Privacy Policy.
