Microsoft Released An emergency improvement to shut down a vulnerability in its sharepoint software that hackers have exploited widespread attacks on businesses and at least some federal agencies.
The software giant said on Saturday that it was known about “active attacks” that exploits weaknesses in the program, a product that allows companies and other businesses to create a website.
Hackers dissolved universities and energy companies with American federal and state agencies through vulnerability, According To Washington Post.

The attack was a so-called “zero-day” exploitation, or when hackers take advantage of unknown vulnerability, often to steal sensitive data and passwords. The vulnerability can also allow hackers to reach the services associated with Sharepoint, including Onedrive and Team.
“Once inside, they can access all Sharepoint materials, system files and configurations and move later to Windows Domain,” mentioned in one in the Netherlands-based research company Eye Safety Research note About violations.
It states, “Because Sharepoint often connects with core services such as Outlook, teams and ONEDRIVE, a violation can quickly promote data theft, password harvesting and lateral movement in network.”
Microsoft said in his blog post that it had compromised at least dozens of systems worldwide. Security engineers said the attacks occurred in waves on 18 and 19 July.
Although the scope of the attack is still being evaluated, the US Cyber Security and Infrastructure Security Agency (CISA) warned that Effects can be widespread And recommended that any servers affected by exploitation should be disconnected from the Internet until they are patched.
