What our analysis found

Einvoice Signing, used by 100,000 people, showed no malicious code in Extension Auditor's review. It comes from a publisher with 2 extensions and was last updated in August 2026.

Analyst notes

The extension's code only relays messages between whitelisted e-invoice web pages and a local native signing application via nativeMessaging. There is no data exfiltration, code injection, obfuscation, or remote code loading. The broad content script matches and 'scripting' permission are necessary for its multi-site signing functionality and are not abused.

thuận tiện, dễ sử dụng!

Mai Mai·8 Aug 2024

Khi tôi còn nhỏ, tôi rất hay thắc mắc là “Mình là ai? Mình sinh ra để làm gì? và Mình từ đâu tới?” Và điều đó khiến cho tôi luôn mơ hồ về tương lai, về cuộc sống và đôi khi tôi cảm thấy không biết mình đi học để làm gì, đi làm để làm gì. Nhưng giờ đây tôi đã tiên tri được vào một ngày nào đó thiên hạ sẽ tốn thời gian đọc comment của tôi. Và ngày đó chính là ngày hôm nay
