Outlook’s email software is believed to have infected tens of thousands of businesses, government offices, and schools in the United States, people who were briefed on the issue told The Wall Street Journal.

Many of the victims of the attacks that Microsoft said were carried out by a network of suspected hackers in China appear to be small businesses, state governments, and local governments. As of Friday, estimates of worldwide casualties are approximate and widespread. Tens of thousands of customers seem to have been affected, but people said the number could be higher. According to one, it can exceed 250,000.

Many of the affected people may have little intelligence value for the target of the attack, but they are also likely to offset the targets of high-value spies, one said. ..

Hackers have exploited a series of four flaws in Microsoft’s Exchange software to break into email accounts, read messages without permission, and install unauthorized software, the company said. These flaws depended on previously unpublished software bugs and are therefore known as zero-days among cybersecurity professionals. This suggests advanced technology by hackers.
