Iran is operating on multiple axes to project power in 2025. It combines proxy warfare, long-range strike options, and increasingly aggressive cyber activity to impose cost, create ambiguity, and shape adversary behavior. This is not a single-mode campaign. It is a layered campaign designed to exploit gaps in maritime security, critical infrastructure defenses, and information ecosystems.

Start with the proxies. Tehran has poured money, materiel, and doctrine into groups that can harass shipping, strike forward against Israel, and pressure local governments without exposing Iranian forces to direct reprisal. The most visible example through late 2024 was the Houthi campaign against vessels transiting the Red Sea and Gulf of Aden. That campaign demonstrated how relatively cheap weapons and unmanned systems can shut or sharply divert a vital global trade artery and force costly naval and commercial responses.

At the same time Tehran has shown a willingness to use direct long-range fires when it judges the strategic payoff is worth the risk. The October 2024 missile and drone barrages directed at Israel underscored two points. First, Iran has the reach to threaten regional adversaries with massed kinetic salvos. Second, massed salvos are designed to saturate defenses and impose political and logistical burdens on the target. Opponents can intercept many incoming weapons but the requirement to do so consumes resources and can raise the political temperature regionally.

Cyber and influence operations are the other pillar. U.S. and allied agencies have repeatedly warned that Iranian state-affiliated actors and Iran-linked groups are targeting critical infrastructure, health care, government networks, and private-sector victims using credential abuse, brute force, and access-for-sale models that enable follow-on ransomware and destructive operations. Separately, private sector telemetry and vendor reporting documented coordinated influence and information operations aligned with Tehran’s strategic objectives. Those capabilities give Iran low-cost, deniable options to disrupt, surveil, and coerce.

The operational pattern is clear and persistent. Iran enables proxies to generate first-order kinetic effects in maritime and border spaces. It fields long-range strikes to escalate or deter as needed. And it pushes cyber and influence campaigns against soft targets to amplify uncertainty and economic pain. The result is a hybrid toolbox that is cheap to employ, hard to attribute conclusively in real time, and effective at imposing friction on Western and regional actors.

Implications for 2025 and immediate risks.

  • Maritime chokepoints will remain a pressure point. Adversaries can use small boats, unmanned surface vessels, drones, and limpet-style attacks to force rerouting around southern Africa or to exact ransom or political concessions. Expect intermittent spikes of activity tied to regional flashpoints.
  • Operational technology and industrial control systems are attractive targets. Iranian-affiliated cyber actors have pursued brute-force and credential-based access that can lead to ransomware or manipulation of OT environments. That attack path is lower-cost for the attacker and potentially high-impact for defenders.
  • Information operations will continue to be used to shape narratives, mask attribution, and influence third-party decisionmakers during crises. Microsoft and other telemetry providers have recorded coordinated surges tied to regional events. Expect more of the same when kinetic pressure rises.

Three plausible escalation scenarios to plan for. 1) Maritime pressure campaign plus cyber nuisance. A renewed Houthi-style interdiction effort targets commercial traffic, while Iranian cyber actors conduct lateral intrusions against shipping logistics providers and port terminals to amplify delay and economic disruption. This multiplies chokepoint effects and complicates interdiction responses. 2) Targeted destructive cyber against national infrastructure. Attackers leverage access obtained via credential stuffing and misconfigured remote access to disrupt energy, water, or transport nodes. Even limited outages will have outsized political impact. 3) Limited kinetic strike with information campaign. Tehran or its proxies launch a missile or drone strike and simultaneously roll out an influence operation that spoofs evidence or floods social platforms to delay attribution and raise the political cost of a proportional response.

What defenders should do now. This is a short list of non-ideological, operational priorities for government and industry. 1) Harden identity and access. Enforce multifactor authentication, reduce exposed remote access, and treat credential abuse as the primary intrusion vector. CISA and partner advisories include concrete IOCs and mitigations. 2) Protect OT with segmentation and detection. Isolate ICS networks, deploy anomaly detection tuned for process signals, and run red-team exercises against control systems. Assume adversaries will try to pivot from IT to OT. 3) Harden maritime and logistics chains. Increase convoy escorts where necessary, expand vetted private-public escorts, and place redundancy into routing and insurance contracts. Prepare for episodic rerouting costs. 4) Improve attribution timelines. Invest in telemetry sharing, pre-authorized cross-border forensic cooperation, and private sector briefing channels so that attribution moves from weeks to days. That compresses the window for adversaries to benefit from plausible deniability. 5) Build public resilience to influence ops. Pre-bunking campaigns, platform cooperation on takedowns, and clear incident messaging reduce the strategic payoff of information attacks. 6) Exercise escalatory control. Governments must rehearse calibrated responses that mix sanctions, targeted strikes on logistics, cyber countermeasures, and diplomatic levers. Overreliance on single-tool responses invites exploitation.

Bottom line. Iran’s approach is pragmatic and portfolio-driven. It blends proxies, missiles, and cyber tools to achieve political effects while managing escalation risk. That hybrid posture exposes predictable vulnerabilities. Fix the basics first. Harden access controls, protect industrial systems, defend maritime chokepoints, and shorten the attribution timeline. If policymakers and industry fail to do those things, Iran will keep exploiting cheap technologies to extract outsized leverage at low cost. The remedy is straightforward. It is time to treat hybrid attack surfaces as national strategic vulnerabilities and resource them accordingly.
