Massive Email Leak: 6.8 Billion Addresses Exposed!

A hacker operating under the alias Adkka72424 has reportedly leaked approximately 6.8 billion unique email addresses. This claim, which is currently unverified, follows a previous leak of over 3.3 billion emails two years prior. Researchers analyzing a sample of the 150GB archive suggest that after removing unusable entries, around three billion emails could be viable.

This extensive leak positions it among the largest in history and represents a significant boon for cybercriminals. The data is particularly valuable for those engaged in social engineering tactics. By compiling detailed victim profiles from this information, attackers can design highly targeted phishing campaigns, aiming to illicitly obtain credentials or induce fraudulent wire transfers.
