Sam Curry, a self-proclaimed bug bounty hunter and hacker, posted about the surprise payment on Twitter.
"It's been a little over 3 weeks since Google randomly sent me $249,999 and I still haven't heard anything on the support ticket," said Curry. "Is there any way we could get in touch @Google? (it's OK if you don't want it back...)."
Curry included a snapshot of the direct deposit from the search engine giant.
Google confirmed it mistakenly paid the hacker $249,999.
"Our team recently made a payment to the wrong party as the result of human error," a Google spokeperson told National Public Radio. "We appreciate that it was quickly communicated to us by the impacted partner, and we are working to correct it."
KTVU spoke with Curry Tuesday, and he said Google ended up sending him wiring instructions for him to send the money back through a local bank. Sadly, he said, the full amount went back to Google and there was no offer to compensate him for his time.
