Overview
Digital cryptocurrencies have surged in popularity, attracting both investors and cybercriminals. While Bitcoin (BTC) and Ethereum (ETH) remain primary targets, emerging currencies like Stellar Lumens (XLM)—also known as Lumen—are increasingly vulnerable. A recent attack on the BlackWallet.co platform highlights rising security concerns in the crypto space.
Incident Details
Hackers compromised the DNS records of BlackWallet.co, redirecting users with balances exceeding 20 XLM to a malicious wallet. By the time of reporting, the attackers had stolen approximately 670,000 Lumens (~$400,000 USD).
Attack Methodology:
- DNS Hijacking: Exploiting code injection vulnerabilities to alter domain records.
- Fund Diversion: Stolen XLM was transferred to Bittrex, a cryptocurrency exchange, likely for money laundering.
Response & Mitigation
BlackWallet’s founder (orbit84) issued warnings via Reddit, urging users to:
- Move funds to secure wallets.
- Disable JavaScript when accessing crypto sites temporarily.
- Collaborate with Stellar Development Foundation (SDF) and Bittrex to trace stolen assets.
