#WIF suddenly spiked 26%, is Korean capital rushing in?
Recently, the altcoin market has started to show clear signs of recovery, and leading the charge once again are meme coins.
dogwifhat (WIF) saw a massive surge of over 44% in the last 24 hours, although it has since pulled back, it’s still maintaining around a 26% gain, shooting straight into the top three on the market gainers list. Many are asking: what exactly happened with WIF this time?
The answer is actually pretty simple – the South Korean exchange Upbit has listed WIF.

#Upbit listing ignited market sentiment directly
For many seasoned traders, just seeing the words 'Upbit listing' probably makes it clear why the price spiked suddenly.

It seems that the DeSci sector is currently in the market spotlight. In recent days, there has been a powerful spike in interest towards tokens in this direction, triggered by several key events.
📈 Skyrocketing Bio Protocol (BIO): Listing on Upbit
The main growth driver for the sector is the explosive surge of the BIO token, tied to its listing on the largest South Korean exchange, Upbit. This event has created a real buzz, especially among Asian retail investors:

South Korea’s largest crypto exchange is still working to recover from this week’s major security incident, but new findings point to a deep-rooted flaw inside its own wallet system. Upbit revealed that it identified and patched a critical vulnerability during its probe into the $30 million exploit — a weakness that allowed attackers to analyze wallet signatures in a way that should never be possible on a blockchain network.

A Rare Wallet Bug That Exposed Predictable Signature Patterns
Upbit CEO Oh Kyung-seok confirmed that investigators found a defect in the exchange’s internal wallet software. Under specific conditions, the system generated weak signature data, creating predictable patterns in past transactions. Although private keys are normally mathematically impossible to derive from blockchain activity, these patterns could have revealed portions of certain keys through advanced cryptographic analysis.
The vulnerability was detected only after Upbit launched a full system-wide audit on November 27, following irregular withdrawals of Solana-ecosystem tokens. The review covered networks, wallet architecture, signing mechanisms and security infrastructure. The company immediately fixed the flaw, shut down deposits and withdrawals, and began an emergency rebuild of its wallet systems.
Upbit confirmed total losses of roughly 44.5 billion KRW (~$30 million). Customer assets accounted for 38.6 billion KRW (~$26 million), and the exchange has already frozen about 2.3 billion KRW (~$1.5 million) linked to suspicious transactions.

Expanded Investigations and Ongoing Infrastructure Repairs
Upbit said it is conducting an enhanced internal review and will reimburse all customer losses using its own reserves. Services will fully reopen once the platform completes a final inspection of all wallet systems.
The breach forced Upbit to suspend withdrawals on November 26 after detecting irregular activity involving SOL, ORCA, RAY, JUP and several other Solana-based assets. Remaining funds were quickly transferred to cold storage while engineers began rebuilding parts of the wallet infrastructure.
Upbit, operated by fintech firm Dunamu, remains South Korea’s largest crypto exchange by trading volume. Dunamu is preparing for a merger with Naver ahead of a public listing, and the company stated that the security incident has not affected those plans.
South Korean authorities have launched their own investigation, reviewing both the unauthorized withdrawals and the wallet vulnerability disclosed by the exchange.
