Yahoo is ready to confirm a massive data breach that affected its service that has exposed several hundred million user accounts.

“Yahoo is poised to confirm a massive data breach of its service, according to several sources close to the situation, hacking that has exposed several hundred million user accounts.” reported the website recode.net.

“While sources were unspecific about the extent of the incursion, since there is the likelihood of government investigations and legal action related to the breach, they noted that it is widespread and serious.”

In August, the notorious hacker Peace advertised 200 Million Yahoo accounts on Dark Web, and the company is aware of the sale.

Peace offered for sale the 200 million of Yahoo account credentials (from “2012 most likely,”) on The Real Deal black marketplace. Yahoo was informed of the events and launched an internal investigation avoiding public comment on the case. The hacker was offering the data leak for 3 bitcoins (roughly $1,800 at the time of the disclosure).

While the Yahoo security team was investigating the incident, the company suggested its customers to use strong passwords, one for each web service they use, and enable two-factor authentication when it is available.

Security experts believe its question of hours before the Yahoo will publicly confirm the data breach that caused at least the exposure of 200 million of Yahoo account credentials.

Of course, the news will have a significant impact on the company because the hackers attacked the core service of the IT giant. Analysts speculate a possible interference with the announced $4.8 billion sale of the company to Verizon.

Stay Tuned!
