The Iran War: What You Need to Know

Insikt Group reports heightened cyber and physical threats stemming from escalated US-Iran geopolitical tensions. The Iranian-aligned threat group GreenGolf, also known as MuddyWater, is conducting large-scale data exfiltration campaigns targeting aviation, energy, and government sectors across the Middle East. Utilizing the ArenaC2 framework and exploiting recent CVEs, the group has compromised over 12,000 systems to steal sensitive personal and corporate data. Concurrently, Iraqi Shi'a militias under the Islamic Resistance in Iraq umbrella continue drone and missile strikes against GCC infrastructure despite ceasefire agreements. Organizations in the US, Israel, and Gulf states face elevated risks to critical infrastructure and data integrity. Immediate mitigation requires enhanced monitoring of internet-exposed systems, strict credential management, and preparedness for regional supply chain disruptions amidst ambiguous ceasefire enforcement in the Strait of Hormuz.

Last updated: 17 April 2026 at 1800 GMT New from Insikt Group: Iran War — Future Scenarios and Business Implications Insikt Group has published a dedicated Cone of Plausibility analysis examining how the Iran conflict could evolve over the next 6–12 months — from a fragile ceasefire baseline to regional war, regime collapse, and nuclear crisis. Each scenario includes business implications and 0–90 day priority actions. Read the full analysis. This report is updated as the situation evolves across the geopolitical, cyber, and influence operations dimensions of this conflict. It will be of greatest interest to organizations in the US, Israel, and Gulf states concerned about targeting by Iranian state-sponsored or state-aligned threat actors, as well as those with exposure to energy markets, maritime shipping, and critical infrastructure potentially impacted by regional escalation. The Latest Updates Geopolitical Landscape Strait of Hormuz declared open; blockade status remains ambiguous. Iran and the US both announced on April 18 that the Strait of Hormuz is open to commercial shipping, following a Lebanon ceasefire agreement. Iran stated ships must take a "coordinated route" running close to its coastline, suggesting it retains some administrative role in transit. President Trump separately confirmed the US blockade of Iranian port traffic remains in place, leaving the practical enforcement picture unclear. Insikt Group assesses that while the announcement represents a meaningful de-escalation signal, the divergence between Iranian route requirements and the US blockade's continued status means the Strait's governance remains contested — and the risk of renewed disruption remains elevated until the terms are codified. Pakistan facilitating second round of US-Iran talks. A Pakistani delegation including Chief of Defense Forces Asim Munir met with Iran’s top negotiating officials in Tehran on April 16. Iran’s parliament has signaled a hard line: the ceasefire expiration must yield either international recognition of Iranian control over the Strait of Hormuz, or a return to war. Iraqi Shi‘a militias continue attacks despite ceasefire. Since the April 7 ceasefire, Iraqi Shi‘a militias - operating under the Islamic Resistance in Iraq (IRI) umbrella - have continued drone and missile strikes against GCC infrastructure in Bahrain, Kuwait, and Saudi Arabia, and targeted Iranian Kurdish dissident groups in Iraqi Kurdistan. Drone attacks at Baghdad International Airport on April 8 targeted a convoy carrying FBI personnel. Insikt Group assesses that Iran’s diminished command and control has afforded militias greater tactical autonomy, and that they do not perceive their operations as fully subject to the ceasefire. If the ceasefire collapses, militia activity will likely intensify significantly. Israel-Lebanon ceasefire announced; durability uncertain. President Trump announced a ten-day ceasefire between Israel and Lebanon beginning April 16. The first direct Israeli-Lebanese diplomatic talks since 1993 were held on April 14, facilitated by US Secretary of State Rubio. Hezbollah has denounced the talks; Lebanese President Aoun declined direct engagement with Israeli PM Netanyahu, citing the need for a ceasefire before direct negotiations. Insikt Group assesses this diplomatic engagement increases opportunities for de-escalation in Lebanon, but significant hurdles remain. Cyber Threat Landscape GreenGolf (MuddyWater) conducting large-scale data exfiltration across the Middle East. Oasis Security reported on April 14 a multi-stage campaign attributed to infrastructure overlapping with GreenGolf, targeting more than 12,000 internet-exposed systems across aviation, energy, infrastructure, and government sectors across the Middle East. The campaign exploited five newly disclosed CVEs for initial...
