Possible theft through email addresses is expected, huge companies warned on Monday. They told their clients that they should expect to receive an email coming from a seemingly official account coaxing account owners to give their account name and passwords.

About twelve large companies announced over the weekend that hackers may have gained access to their email addresses due to a security breach in Epsilon. Epsilon is a company located in Dallas that manages email communication of many companies.

Some of the companies in question are Barclays Bank, Capital One Financial Corporation, JPMorgan Chase & Company, and Best Buy Company. These are major players with very important client data base.

Epsilon already confirmed Friday that their security system had been breached and email addresses of customers were exposed. They, however, reassured the public that no information – other than email addresses – were accessed by hackers.

However, email addresses are very important tool for spammers, hackers, and thieves. They can use this information to contact bank clients and trick them in to giving up their log-in details. Hackers can also make it seem like those emails are official and are from your bank. If not stopped, you can unknowingly handing these hackers your money.

That breach in security can make the phishing attacks more proficient because email recipients actually have an account with the bank or the company. Phishing is a hacker’s way to acquire sensitive data like credit card details and passwords.

The said incident also caused Epsilon, which has over 2,500 clients, tons of money after their shares fell by 4.45 per cent Monday.

Tiger Woods wished to play in the first FedEx Cup playoff event with the hopes that it won’t be his last.

Woods officially entered The Barclays last Thursday that will start on Aug. 26. It would be the first of four playoff events that will conclude the Tour Championship and a $10 million prize to the winner of the yearlong FedEx Cup competition.

Woods is No. 108 in the standings and is eager to go further down the list. Of course, that would depend on the outcome this week at the Wyndham Championship. Only the top 125 players are included for The Barclays which will be held at Ridgewood Country Club.

Woods didn’t play in Ridgewood’s last 2008  tournament. He missed the FedEx tourney due to his knee surgery. It’s the only time that he did not claim the $10 million prize since the game began in 2007.

Now, his goal is just to get to as many playoff events as he can.

Right after The Barclays, the top 100 will precede the second round, the Deutsche Bank Championship outside Boston, which will end on Labor Day. That will be the final event before U.S. Ryder Cup captain Corey Pavin will pick his four wild-card picks.

Woods will play, and Pavin said that Woods is on top of the list.

Players are divided at The Barcleys based on their standing in FedEx Cup. Pavin is currently on No. 107. However, he’s not sure whether to play Ridgewood due to a summer schedule of four majors in a five-week stretch.
