By By By Jonathan DienstAssociated PressAug 16, 2017 09:17:07Microsoft is investigating whether an online attack on Facebook and Google may have been carried out to steal information about employees’ personal data, according to a person familiar with the matter.

The person, who spoke on condition of anonymity because the investigation is ongoing, said the company is looking into whether it was a breach of the social media company’s network security, which requires companies to protect employees’ data against unauthorized access.

Microsoft said in a statement that it is “aware of an issue that could affect a number of our systems.”

The statement didn’t provide further details about the issue.

Microsoft has not publicly acknowledged that it was hit with a hack.

A spokesman for the company said Tuesday that the company was “continuing to review” the issue and has not yet provided more details.

The hack occurred on Monday when the Facebook account for an employee who was a senior director at a large software company that had a contract with Microsoft ended and it became publicly available.

The Facebook account contained a password reset button for the employees email account.

The person said the account was breached by an attacker who had gained access to the computer’s network.

The company said it immediately shut down the account.

The breach has left Microsoft reeling from a series of social media and personal data breaches, including one in July of this year in which a Russian hacker stole information about more than a million Facebook users and employees.

The Microsoft hack was the latest in a series that has revealed personal data from more than two million employees.

In September, Google revealed a separate data breach involving more than 10 million users of its Gmail service.

That breach led to the resignation of Google Vice President Joe Sullivan and led to Google becoming the target of a class-action lawsuit filed in California by some 2.5 million former employees and former users of Gmail.

Google said Tuesday it was investigating whether it may have had to close some of its systems that use its Gmail messaging service after the hack.

The information disclosure by Microsoft came just days after the FBI, in its annual report, warned of a “potential cyberthreat” to its system and urged companies to take steps to protect themselves.

The federal government’s cybercrime task force issued a statement Tuesday warning that the threat posed by cybercriminals was growing and that criminals were now using new means to attack the United States and its allies.

It said the threat has escalated as companies have increased their efforts to protect sensitive information and the United Nations has increased its cooperation with the U.S. government to increase its cyberthreat response.

In a letter sent Tuesday to the U-S.

Treasury Department, the U.-S.

Government Accountability Office said it is investigating possible government data breaches at three companies in recent years and has called on the Treasury Department to take a closer look at these data breaches.

The GAO said it was concerned by the use of information sharing between the Department of Homeland Security and other federal agencies to share information about cyber threats, and that the sharing of cyberthreat information with the private sector has increased in recent months.

The agencies are using DHS data, which includes threat indicators, to make decisions about sharing sensitive data, it said.
