Targeted Phishing Campaign Active in Israel Exploits Compromised Email Accounts
Shimiโs Cyber World has learned of a targeted phishing campaign currently active in Israel, as reported by the Israel National Cyber Directorate (INCD). The campaign leverages compromised email accounts within specific organizations to propagate further phishing attempts.
The INCD recently received a report detailing an incident where a userโs email inbox within an organization was breached. The attacker subsequently exploited this access to distribute a phishing scheme to numerous email accounts across various other organizations. This indicates a supply-chain style attack, where an initial compromise is used as a launchpad for broader malicious activity.
Organizations are strongly advised to review the indicators of compromise (IOCs) provided by the INCD and implement them across all relevant organizational security systems. Proactive monitoring and immediate action are crucial to mitigate the risks associated with this ongoing threat.
