SEAL Launches Global Phishing Defense Network Featuring Major Cryptocurrency Wallets
MetaMask, Phantom and other leading cryptocurrency wallets have partnered with Security Alliance to launch a global phishing defense network after cryptocurrency phishers stole more than $400 million in the first half of 2025.
“We are joining forces to launch a global phishing defense network that can help protect more users across the entire ecosystem,” the MetaMask team said on Wednesday.
SEAL said the new defense network will “allow anyone in the world to build a decentralized immune system for cryptocurrency security that can prevent the next major phishing attack.”
“Decentralized immune systems” include MetaMask, Phantom, WalletConnect, and Backpack.
This will be operated in conjunction with SEAL’s ‘Verifiable Phishing Report’ system announced last week. A new tool allows security researchers to prove that malicious websites actually contain the phishing content they claim they are seeing.
The fight against cryptocurrency drains
SEAL explained that cryptocurrency leakers are becoming a growing problem, as they have evolved tactics to evade traditional defense measures.
New ways to lure victims include rotating landing pages faster when blocklists are updated, moving to offshore hosting when infrastructure providers crack down, and using cloaking technology to prevent automatic scanning.

“Drainers are a constant game of cat and mouse,” said Ohm Shah, security researcher at MetaMask.
Working with SEALs allows wallet teams to be more nimble and put research into practice, “effectively throwing a wrench in the infrastructure of the drain,” he added.
Distribute to as many wallets as possible
This partnership enables an end-to-end pipeline where user-submitted reports are automatically verified and shared across all participating wallets, providing immediate protection against emerging phishing threats.
“Anyone with a valid report can issue phishing alerts to network participants in real time without special permission,” SEAL explained.
“This means faster response times to new phishing threats and more money saved. We want to get this data into as many wallets as possible.”
According to CertiK, phishing attacks accounted for the most security incidents in the first half of the year and led to the theft of more than $400 million in cryptocurrency.
