EBay was attacked and urged 0.145 billion million users to change their passwords

According to Reuters, May 23, eBay said on Wednesday that the cyber attacks it launched three months ago have threatened customer data security. The company urged 0.145 billion million users to change their passwords. From the end of February this year to the beginning of March, eBay was attacked by a mysterious hacker, and users' email addresses, passwords, birthdays, and other information were stolen.

A spokesman for eBay said many accounts may be in danger, but refused to disclose the specific number of accounts. The company said there was no evidence that someone had accessed the PayPal payment company's financial or credit card information without authorization because it was separately encrypted. EBay shares fell 0.2% on Wednesday afternoon.

Network security experts advise eBay customers to be vigilant against fraud, especially if they use the same password on other accounts. "This attack is not only harmful to eBay, but also to all websites," said Michael Coates, Security Director of Shape Security ." He said that the company generally only requires users to change their passwords.

He said that once the password is deciphered, attackers may use automated software to log on to thousands of popular services, including Facebook, Twitter, and online banking. However, a eBay spokesman said that the company's request for password modification was not a constant warning, and the company used cutting-edge proprietary technology to protect the password.

EBay said it was investigating the attack with the help of law enforcement agencies. A spokesman for the company said: "Currently, we cannot disclose the specific numbers of affected accounts. But we think it may involve many accounts ." EBay says there are no signs of rising fraud and no evidence that the PayPal payment service is under attack.

EBay has hardly disclosed any information about how hackers intrude into the website. The company only indicates that hackers may have obtained logon certificates from a few employees to access eBay's enterprise network. EBay said they discovered the attack in early May and immediately found security experts and law enforcement agencies to investigate it.
