The Potential for Iranian Cyber Response

Speak With A Security Expert Now

The Threat

On January 4th, 2020, the Department of Homeland Security issued an official summary of the escalation and threats to the United States following the targeted US airstrike that killed the Iranian General, Qasem Soleimani on January 2nd, 2020 [1]. Iranian leadership has promised retaliation for the strike which may take the form of both physical and cyber operations. Historically, suspected Iranian APT groups have targeted both governments and private businesses [2]. There is the possibility that organizations previously compromised by Iranian APT groups will be targeted with destructive malware, as past unidentified compromises would allow for fast retaliatory actions. eSentire has not observed any increase in attacks linked to this topic across its customer base.
