South Korea’s Secret Phrase Disaster: $4.8M Stolen!

by

Oh, the Madness!

Once upon a time, in a land of taxes and tiny computers, a silly little tax office in South Korea made a most dreadful mistake. They shared a photo of their shiny new crypto wallets-only to discover, oopsie, that the magic words (seed phrases) were on full display! And thus, $4.8 million vanished into the void, like a chocolate factory with a broken door.

What to Know:

  • The National Tax Service lost about $4.8 million in crypto after showing off their wallets’ secret phrases. A silly mistake, indeed!
  • This is the country’s second time losing crypto in a silly way. First, they lost 22 BTC (about $1.5 million) in 2021. Second, they lost $4.8 million. What a lovely pattern!
  • The tax office asked for help from the police and promised to check their security. Probably not very seriously, though.

South Korea’s tax authorities lost $4.8 million of seized crypto after displaying the wallets’ secret phrases in a photo. What a silly, silly thing to do!

The crypto was taken immediately after the NTS shared a photo that included hardware wallets and their secret phrases. The service apologized, saying, “We didn’t realize our silly mistake!”

“In an effort to provide more vivid information, we did not realize that sensitive information was included and carelessly provided the original photo,” the tax office said. “This is entirely the fault of the National Tax Service (NTS), with no excuse.”

This is at least the second time something like this has occurred in the country. South Korean authorities faced scrutiny over a separate failure in which Seoul’s Gangnam police allegedly lost 22 BTC (roughly $1.5 million) in a 2021 hacking case. The thieves were recently caught. A happy ending, perhaps?

The new case involves a taxpayer who owed the NTS capital gains tax, which led to the individual’s home being raided. The authorities took control of at least four hardware wallets and cash. They then photographed the seized items, which included at least two seed phrases, and shared the unblurred photo publicly. What a silly, silly idea!

The NTS requested police intervention to recover the stolen cryptocurrency. The tax authority also revealed plans to conduct an external review of its overall security system and to overhaul the entire manual for the process from the seizure to the sale of virtual assets. A grand plan, indeed!

Koo Yun-cheol, South Korea’s deputy Prime Minister and Minister of Finance and Economy, confirmed the leak in an X post on Sunday. “We must be more careful!” he said, while probably thinking, “How could we be so silly?”

Koo said several government agencies, including the Financial Services Commission and the Financial Supervisory Service would investigate the leak. He also said they would scrutinize how government agencies and public institutions seize and manage digital assets to prevent recurrence. “We’ll never make this mistake again!” they all said, while secretly plotting to do it again next week.
