Binance co-founder Changpeng Zhao has cautioned cryptocurrency users against the immediate use of newly acquired hardware wallets, recommending a stringent “quarantine” period. His advice comes on the heels of a security breach involving a local Ledger distributor in Southeast Asia, which resulted in losses exceeding $86 million.
Supply Chain Vulnerabilities Exposed
Recent incidents highlight a shift in attack vectors, with bad actors now targeting the delivery process of devices, not just software vulnerabilities. Zhao advises against transferring substantial assets to addresses created on newly purchased devices or new software downloads immediately after acquisition. According to Zhao, a hardware wallet should remain unused for at least two weeks, allowing users to monitor for potential security alerts or notifications.
“Managing digital assets independently brings extra responsibility as physical devices can be altered before reaching end-users, and official software sites can be targeted,” Zhao emphasizes.
The intent is to allow time for early detection of any widespread security breaches. If distribution channel devices have been tampered with, this two-week buffer is deemed crucial for blockchain analysts to detect initial theft transactions and issue warnings.
$86.9 Million Exposed in Ledger Breach
On October 9, Ledger announced it had suspended sales via its distributor CryptoBilis. Blockchain analysts traced over $86.9 million in unauthorized exits from hundreds of wallets associated with investors in Malaysia, Indonesia, and the Philippines across the Bitcoin, Ethereum, and Tron networks.
Ledger, a leading hardware wallet manufacturer, disclosed that attackers physically intercepted packages at the distributor’s intermediary depots, swapping original setup instructions with pre-generated seed phrase cards. The company asserted the incident did not affect its factory manufacturing, firmware, or Ledger Live application, with the issue isolated to the logistical chain involving CryptoBilis.
Customers who bought devices in the last 90 days were cautioned to refrain from activating their products and to immediately relocate their assets to new addresses if they suspected risk.
“The attack targeted the distribution process, particularly exploiting physical interventions at intermediary storage facilities,” Ledger stated.
Similar Breaches Impact Other Manufacturers
The Ledger incident underscores a broader trend impacting the cold wallet market. In the past three months, physical delivery processes have emerged as a key risk area. In August, Coldcard manufacturer Coinkite reported that third-party distributor systems were compromised.
In September, Trezor confirmed a data breach affecting 80,000 U.S. customers after its logistics contractor ShipMonk was infiltrated, exposing buyers’ real names, phone numbers, and home addresses.
Given these developments, purchasing wallets through local marketplaces or intermediary distributors is increasingly perceived as high-risk. For large-scale investors, ordering directly from manufacturers, directing delivery to neutral addresses, and enforcing a mandatory waiting period before device use are considered more robust security measures.
