Microsoft Exchange Server hacked

In early January the Microsoft Exchange Server was hacked. The Microsoft Exchange Server hosts email and calendar services. The initial hackers were Chinese cyber spies, but after that other intruders also got in, using the initial breach as their way in. There are hundreds of thousands of victims in all sorts of organizations.The hack can be an existential threat for victims who did not install the patch (the update) in time. For them that would mean there are hackers still inside of their systems. Even after the update to fix the issue was released on March 2nd, a third wave of infections started. This happened because Microsoft leads the software market and offers a single point of attack.Up until now Microsoft has refused to tell the press how many customers are infected, but David Kennedy, CEO of cybersecurity firm TrustedSec, said hundreds of thousands of organizations could have been exposed to the hack. "Anybody that had Exchange installed was potentially vulnerable," he said. "It's not every single one but it's a large percentage of them."Katie Nickels, director of intelligence at the cybersecurity firm Red Canary, warned that installing patches won't be enough to protect those already infected. "If you patch today that is going to protect you going forward but if the adversaries are already in your system then you need to take care of that," she said.Protect your corporate apps with our web app isolation.Read more about this: Source
