AT&T successfully blocks hacking attempt

Cybercriminals recently launched an unsuccessful attempt to extract confidential customer information from AT&T's website, prompting the company to email customers about the attack.

The hackers tried to use an autoscript to link phone numbers to AT&T online accounts, which could have potentially allowed the criminals access to customer information through the company's website.

"We recently detected an organized and systematic attempt to obtain information on a number of AT&T customer accounts, including yours," AT&T said in an email to customers. "We do not believe that the perpetrators of this attack obtained access to your online account or any of the information contained in that account."

Fewer than 1 percent of AT&T's users were affected, said company spokesman Mark Siegel, according to Bloomberg. The recent attack is unrelated to last year's incident when hackers collected email addresses of Apple iPad users, Siegel said.

The cyberattack is one of several recent data breach attempts on large companies, including Microsoft's Xbox Live system being hit with a phishing attack this week. According to reports, hackers successfully charged illegitimate payments to Xbox Live users' credit cards and bank accounts.
