What happened
Since September 2026, organisations in Israel have been targeted by phishing emails impersonating the Israel Tax Authority that distribute SimpleHelp remote monitoring and management software disguised as tax documents. No software vulnerability is exploited; the campaign abuses a legitimate RMM tool. Investigators suspect MuddyWater based on targeting and the group's history of abusing remote-access software, but attribution is unconfirmed. The article does not describe specific indicators or remediation steps.
