In the fast-paced world of crypto, security breaches can shake markets in an instant. Today, South Korea's leading exchange, Upbit, announced a significant incident involving abnormal withdrawals from its Solana hot wallets. Around 4:42 AM KST on November 27, 2025, approximately 44.5 billion KRW (about $31.8 million, though some reports cite up to $37-38 million) worth of Solana network assets were transferred to an unknown external wallet.

Upbit quickly responded by suspending all deposits and withdrawals to prevent further losses. In a reassuring move, the exchange stated it would cover all affected assets, ensuring no impact on user funds. This comes just a day after news of a major deal involving Upbit's parent company, Dunamu, and tech giant Naver.

What Went Down: The Details of the Breach

According to Upbit's official update, the irregular activity targeted a range of Solana-based tokens. Hot wallets, which are online storage systems for quick transactions, are often more vulnerable to hacks compared to cold storage. The exchange detected the anomaly swiftly and isolated the issue, but not before the funds were siphoned off.

Reports from sources like CoinDesk and CryptoBriefing confirm the scale of the loss, with assets moved to an unspecified address. Some speculation points to North Korean hackers, a group notorious for targeting crypto exchanges, as noted in Chosun Ilbo.

The Meme Tokens in the Crosshairs

What makes this hack particularly interesting for meme token enthusiasts is the list of affected assets. While it includes staples like SOL (Solana's native token) and USDC (a stablecoin), a big chunk involves popular meme coins that have captured the community's imagination. Here's a breakdown of some key ones:

• BONK: The Shiba Inu-inspired Solana meme coin that's been a favorite for its community-driven vibes and burn mechanisms.
• MEW (Cat in a Dog World)​: A playful token pitting cats against dogs in the meme wars, known for its viral marketing.
• Moodeng (Moo Deng)​: Based on the adorable pygmy hippo that's taken social media by storm, this token embodies the fun, whimsical side of memes.
• PENGU: Penguin-themed, riding the wave of animal memes with a focus on community events and airdrops.
• Official TRUMP: A politically charged meme token tied to the former U.S. president, often volatile with news cycles.

Other tokens hit include ZZ (Double Zero), ACS (Access Protocol), DOOD, DRIFT, HUMA, JTO (Jito and Ionet), JUP (Jupiter), LAYER, ME (Magic Eden), ORCA, PYTH (Pyth Network), RAY (Raydium), RENDER, SONIC (Sonic SVM), SOON, USDC, and WOL.

This mix highlights how meme tokens, often built on Solana for its speed and low fees, are increasingly in the spotlight – for better or worse.

Impact on the Meme Token Market

Despite the hack, Solana's meme ecosystem has shown resilience. As CCN points out, prices for tokens like BONK and TRUMP haven't crashed dramatically, possibly because Upbit's promise to cover losses eases panic. However, it underscores the risks in holding assets on exchanges versus self-custody wallets.

For blockchain practitioners, this is a reminder to prioritize security: use hardware wallets, enable two-factor authentication, and stay informed on exchange protocols. Solana's network itself wasn't compromised – this was an exchange-level issue – but it could lead to short-term dips in meme token liquidity.

Looking Ahead: Lessons from the Upbit Incident

As investigations continue, with forensic teams likely tracing the funds on-chain, the crypto community watches closely. Upbit's swift action and commitment to users set a positive precedent, but it also fuels discussions on better hot wallet protections and regulatory oversight in South Korea.

At Meme Insider, we're keeping tabs on how this affects the broader meme token landscape. If you're holding any of these coins, monitor official channels like Upbit's Twitter for updates. Stay safe out there, and remember: in crypto, knowledge is your best defense.
