Yahoo has become another big tech company which has decided to warn its users if their account is or has been a target of foreign hacker. Google started giving out such warnings in 2012 followed by Facebook and Twitter.
Yahoo said in its statement that they will send notifications to the suspected targets so that they can take steps to secure their online presence.
Hackers from countries such as China and Russia cannot crack corporate or government agency networks and often go for employees’ or relatives’ personal accounts which they can use to send email with malware to the real target. Several studies have shown a very bright chance that same password is being used by most of the people across all social and work networks to log on to work network from home are easy targets for the hackers.
The incidents like Sony Pictures Entertainment and the Office of Personnel Management are part of such attacks by the hackers from North Korea and China. Tom Kellermann, chief cyber security officer at the Tokyo-based security company Trend Micro said that the hackers are not looking for the Christmas photos from the accounts but are targeting people to fulfill specific objectives such as gaining access to Government or Corporate network.
Kellerman mentioned in his statement that if a person is a corporate official of Fortune 1,000 companies, senior executives of U.S. government or if he/she is within one degree separation from them say spouse, child or a deputy then they can be a potential target.
Al Pascual, director of fraud and security at Javelin Strategy & Research said in his statement that the general consumers are not at risk. According to him, the industries which are vulnerable to such attacks include financial services, critical infrastructure, defense and politics.
If you get such notification from any social network or email service provider, the first thing to do is to notify your employer.
