Switzerland’s federal IT office says hackers exploited vulnerabilities to breach its Microsoft SharePoint servers and compromised approximately 200 accounts.
The Federal Office for Information Technology and Telecommunication (BIT) detected the cyberattack after security specialists noticed unusual activity on its SharePoint servers on July 28.
After confirming the breach, BIT blocked external internet access to SharePoint, patched the suspected vulnerabilities, and reset the passwords for the affected accounts.
"During the analysis, security specialists discovered on Friday, July 31, that the login credentials for several accounts had been compromised," BIT said.
The agency believes the attackers exploited SharePoint vulnerabilities disclosed by Microsoft in mid-July and fixed in the July Patch Tuesday updates. However, it has not disclosed which flaw was used.
