Cryptocurrency companies CoinGecko and Tether are investigating a supply chain email breach attack targeting a newsletter distribution platform.

Tether CEO Paolo Ardoino has warned of potential security risks as scammers target investors with fake token airdrop emails from companies like Bitfinex and Coinbase.

The breach, suspected to be a supply chain attack, may result in phishing threats through fake token launch emails, potentially leading to theft of users' wallet information.

CoinGecko co-founder Bobby Ong confirmed that several crypto firms, including CoinGecko, might be affected by this incident.

Users are advised to be cautious of email newsletters and avoid clicking on any links related to fraudulent CoinGecko tokens or fake airdrop offers.

This incident is part of a series of email-related breaches in the crypto industry, underscoring the importance of verifying the legitimacy of emails offering token airdrops or requiring personal information.

Further details on the amount stolen from the breach will be provided as the investigation progresses, as the industry works to protect users from potential threats.
