Bitfinex's Chief Technology Officer Paolo Ardoino has disclosed details about a thwarted cyberattack targeting the exchange through an attempted "partial payment exploit" involving XRP transactions worth nearly $15 billion.
Key Details of the Failed Attack
- Date of Incident: January 14
- Attack Method: Partial payment vulnerability exploitation
- Targeted Platforms: Bitfinex and Binance
Amount Involved:
- 256 billion XRP sent to Bitfinex (failed)
- 589 billion XRP sent to Binance (failed)
How the Attack Was Attempted
The malicious actor exploited a critical Ripple network vulnerability by manipulating transaction fields:
The attacker sent transactions with mismatched values between:
- The "amount" field (displaying inflated XRP quantities)
- The actual delivered_amount (containing far smaller values)
The strategy relied on exchanges improperly configured to:
- Read only the "amount" field
- Credit accounts based on this inflated value

Why the Attack Failed
Ardoino confirmed Bitfinex's systems were properly configured to:
- Process the "delivered_amount" data field correctly
- Reject any discrepancy between displayed and actual transaction values
Industry Response
Blockchain tracker Whale Alert initially reported the massive XRP transfer but later retracted:
"Issues correctly parsing Ripple node responses led to some erroneous posts."
The attempted attack highlights the importance of:
- Robust transaction validation systems
- Continuous security audits
- Proper node configuration
FAQs About Partial Payment Exploits
What is a partial payment exploit?
A blockchain attack where hackers manipulate transaction fields to trick systems into crediting larger amounts than actually transferred.
How can exchanges prevent such attacks?
By properly configuring software to validate both "amount" and "delivered_amount" fields in XRP transactions.
Was any XRP actually stolen in this attempt?
No. Both attempts against Bitfinex and Binance failed due to proper system configurations.
Why target XRP specifically?
Ripple's protocol design includes transaction fields that can be manipulated if systems aren't properly configured.
