Microsoft hacking campaign expands into ransomware attacks
Over 400 victims hit in hacking campaign exploiting unpatched Microsoft SharePoint servers.
A state-aligned cyber-espionage campaign exploiting Microsoft server software vulnerabilities has escalated to ransomware deployment, according to a Microsoft blog post published late Wednesday.
The group, dubbed ‘Storm-2603’ by Microsoft, is now using the SharePoint vulnerability to spread ransomware that can lock down systems and demand digital payments. This shift suggests a move from espionage to broader disruption.
according to Eye Security, a cybersecurity firm from the Netherlands, the number of known victims has surged from 100 to over 400, with the possibility that the true figure is likely much higher.
‘There are many more, because not all attack vectors have left artefacts that we could scan for,’ said Eye Security’s chief hacker, Vaisha Bernard.
One confirmed victim is the US National Institutes of Health, which isolated affected servers as a precaution. Reports also indicate that the Department of Homeland Security and several other agencies have been impacted.
The breach stems from an incomplete fix to Microsoft’s SharePoint software vulnerability. Both Microsoft and Google-owner Alphabet have linked the activity to Chinese hackers—a claim Beijing denies.
