Crypto hacking group “Pink Drainer” has been linked to a massive heist that stole a total of $4.4 million worth of Chainlink (LINK) from a victim — who was tricked into signing up for an “Increase Approval” feature .

According to on-chain data, a total of 275,700 LINK was stolen from this victim, currently worth $4,330,000 — this occurred within one minute of signing the “Increase Approval” transaction.

Another victim lost $4.4 million worth of LINK, via a phishing scam about 2 hours ago.

Approximately 68,925 LINK was transferred to a wallet labeled "PinkDrainer: Wallet 2" on Etherscan, while another 206,775 LINK was sent to an address ending in "E70e."

Speaking to Cointelegraph, blockchain security firm Scam Sniffer confirmed the latest theft was related to Pink Drainer, but said it was unclear how the victims interacted with the phishing site. Scam Sniffer added that they have identified at least 10 Pink Drainer scam sites in the past 24 hours.

"This is a typical attack where the victim happens to own a large amount of assets," the company added.

Pink Drainer has been linked to multiple Discord and Twitter hacks over the past year, including Evomos, Pika Protocol, OpenAI CTO Mira Murati, and Orbiter Finance.

The group has also orchestrated a series of scams posing as crypto journalists.
