A Fake Security Alert With a $2.56 Million Price Tag
Belgian hardware-wallet maker Ngrave, commonly known as NGRAVE, disclosed on Oct. 19 that attackers hijacked a third-party notification provider serving its LIQUID companion app. The breach allowed criminals to send authentic-looking security warnings directly to customers on Oct. 17. The message claimed a user’s portfolio had been synchronized with a Pixel 9 device in Moscow. Clicking the alert opened a counterfeit Ngrave website featuring a countdown timer and an ominous choice to approve or deny the suspicious activity.
Both paths led to the same trap. Users were prompted to enter their 24-word recovery phrase or Perfect Key, handing attackers everything needed to recreate their wallets. Automated scripts emptied compromised accounts within minutes. Ngrave’s investigation traced approximately $2.56 million stolen from 70 wallet addresses across four networks. Bitcoin accounted for $1.77 million, followed by $454,000 in $XRP, $316,000 in Ethereum-based assets and $18,000 in Stellar.
Attackers Exploited Notification Keys, Not Hardware
The company’s incident report reveals that unauthorized access potentially began Oct. 11, six days before the fraudulent notifications appeared. Attackers obtained one access key and leveraged it to acquire another with broader permissions, including access to certain analytics information. Ngrave detected the malicious alerts within a minute of their appearance at 9:30 p.m. UTC on Oct. 17. Nevertheless, the first wallet was drained six minutes later.
