Crypto cybersecurity firm Trugard and onchain trust protocol Webacy have 
developed an artificial intelligence-based system for detecting crypto wallet 
address poisoning.
According to a May 21 announcement shared with Cointelegraph, the new tool is 
part of Webacy&#8217;s crypto decisioning tools and &#8220;leverages a supervised machine 
learning model trained on live transaction data in conjunction with onchain 
analytics, feature engineering and behavioral context.&#8221;
The new tool purportedly has a success score of 97%, tested across known 
attack cases. &#8220;Address poisoning is one of the most underreported yet costly 
scams in crypto, and it preys on the simplest assumption: That what you see is 
what you get,&#8221; said Webacy co-founder Maika Isogawa.

Crypto address poisoning is a scam where attackers send small amounts of 
cryptocurrency from a wallet address that closely resembles a target&#8217;s real 
address, often with the same starting and ending characters. The goal is to 
trick the user into accidentally copying and reusing the attacker&#8217;s address in 
future transactions, resulting in lost funds.
The technique exploits how users often rely on partial address matching or 
clipboard history when sending crypto. A January 2025 study found that over 
270 million poisoning attempts occurred on BNB Chain and Ethereum between July 
1, 2022, and June 30, 2024. Of those, 6,000 attempts were successful, leading 
to losses over $83 million.

## Web2 security in a Web3 world
Trugard chief technology officer Jeremiah O&#8217;Connor told Cointelegraph that the 
team brings deep cybersecurity expertise from the Web2 world, which they&#8217;ve 
been &#8220;applying to Web3 data since the early days of crypto.&#8221; The team is 
applying its experience with algorithmic feature engineering from traditional 
systems to Web3. He added:
&gt; &#8220;Most existing Web3 attack detection systems rely on static rules or basic 
&gt; transaction filtering. These methods often fall behind evolving attacker 
&gt; tactics, techniques, and procedures.&#8221;
The newly developed system instead leverages machine learning to create a 
system that learns and adapts to address poisoning attacks. O&#8217;Connor 
highlighted that what sets their system apart is &#8220;its emphasis on context and 
pattern recognition.&#8221; Isogawa explained that &#8220;AI can detect patterns often 
beyond the reach of human analysis.&#8221;

## The machine learning approach
O&#8217;Connor said Trugard generated synthetic training data for the AI to simulate 
various attack patterns. Then the model was trained through supervised 
learning, a type of machine learning where a model is trained on labeled data, 
including input variables and the correct output.
In such a setup, the goal is for the model to learn the relationship between 
inputs and outputs to predict the correct output for new, unseen inputs. 
Common examples include spam detection, image classification and price 
prediction.
O&#8217;Connor said the model is also updated by training it on new data as new 
strategies emerge. &#8220;To top it off, we&#8217;ve built a synthetic data generation 
layer that lets us continuously test the model against simulated poisoning 
scenarios,&#8221; he said. &#8220;This has proven incredibly effective in helping the 
model generalize and stay robust over time.&#8221;
