The company has issued a security advisory to warn users that Yahoo Mail Service was hacked, hackers have stolen credentials of its email customers.

Yahoo Mail! is considered one of the largest email service providers, millions of people use is every day, it’s clear that it represents an attractive target for cyber criminals. The day is come, the company issued an official security update for its email users warning of a data breach avoiding to provide the extension of the incident in terms of number of users’ account compromised:

we identified a coordinated effort to gain unauthorized access to Yahoo Mail accounts’, user names and passwords of its email customers have been stolen and are used to access multiple accounts.” reports the update

The hackers have compromised a third-party database without penetrating the servers used for the Yahoo Mail service.

We have no evidence that they were obtained directly from Yahoo’s systems. Our ongoing investigation shows that malicious computer software used the list of usernames and passwords to access Yahoo Mail accounts. The information sought in the attack seems to be names and email addresses from the affected accounts’ most recent sent emails.

One thought on “Yahoo Mail hacked,attackers gain unauthorized access to its accounts

  1. Lets start from the beginning of how this all started.
    Several weeks ago, phishing pages started appearing ( FAKE Yahoo Sign-in’s )
    If any User entered their username and password, their account was instantly compromised, BUT was NOT the Primary target of the Hackers. Primary target was Yahoo Servers.

    Yahoo runs on Linux and not windows(Business Version). Would be safe if you ask the Linux fan club, correct? W R O N G
    After the User entered information, computer was compromised to start the attack on Yahoo using the following Threats( A few examples, more in report )

    Trojan.Hacktool.Linux.Bf.B
    Linux.BackDoor.Unguras.1
    Linux/Rootkit-D
    ELF_PORTSCAN.D

    NOTE: If the Users had thought of checking the URL of the Phishing Page, they would have been ok. By no means was it/they an official Yahoo page

    NOTE: Windows computers can be carriers of Linux Malware without ever affecting it. Mac’s carry this same trait, carry windows malware without ever affecting it
