Block on Trump's Asylum Ban Upheld by Supreme Court
If you are a Superman fan, "kryptonite" is an ugly word.
It's the one material that can weaken and even kill Superman. But Metacert has found a way to use its "Cryptonite" for good.
It's a program that catches phishing links in your email. And there's nothing uglier than a hacker phishing in your email.
Metacert, a company that protects companies that use messaging apps, started by watching chat rooms for fake Ethereum scams. Founder Paul Walsh has now expanded his software to email.
He said the system uses the same infrastructure, with 10 billion classified URLs. He said it has protected over one million crypto users, and turned off phishing for the crypto world in 2017.
"Even when links are shortened, MetaCert unfurls them until it finds the real destination site, and then checks the Protocol to see if it's verified, unknown or classified as phishing," he told TechCrunch. "It does all this in less that 300ms."
Walsh said the service can be installed on a smartphone in less than a minute. It may take a little longer to see if there is market for the Metacert program.
In practice, the software will separate good links from bad ones. A green or red shield will show the difference.
A fake link, for example, would appear in red and a real link would appear green. So in this case, Cryptonite is good.
"With MetaCert's security, training is reduced to a single sentence," Walsh said. "If it doesn't have a green shield, assume it's not safe."
