Wu said he learned that Tether CEO Paolo Ardoino warned that a well-known vendor that manages mailing lists may have been hacked, affecting multiple crypto companies. Ardoino said, "We have received two independent confirmations that a well-known mailing list management vendor used by crypto companies may have been compromised." The specific company name has not been made public yet, but he reminded users to be wary of any emails received in the past 24 hours suggesting crypto airdrops. Ardoino also mentioned, "We have seen phishing CoinGecko emails sent from other customer accounts. There are currently no plans to issue CoinGecko tokens, so don't be fooled by these phishing emails."
