Using an unordered list, summarize the following article with between 4 and 8 key points. Israel wiped out a major military hub in southeastern Tehran, hitting a site that Western intel says was the nerve center for the IRGC. The facility didn\u2019t just house the Quds Force and Basij; it served as the literal \u201cbrain\u201d for Iran\u2019s global hacking campaigns and internal security operations.The facility coordinated intrusion campaigns against adversaries across multiple continents. Yet even as satellite imagery confirmed the compound\u2019s destruction, cybersecurity analysts were documenting a spike in reconnaissance activity emanating from Iranian-linked networks.Tehran\u2019s digital arsenal has proven more resilient than the bombing runs suggest. Handala \u2014 the persona behind the Stryker attack and now assessed as a front for Void Manticore, an MOIS-affiliated state actor \u2014 exemplifies exactly this. It operates as a hack-and-leak engine optimized for psychological disruption: breaking into accessible systems, wiping data, and timing the release of stolen material to maximize pressure on targets.The earlier assassination of Deputy Intelligence Minister Seyed Yahya Hosseini Panjaki, once the man pulling the strings behind Handala and Karma Below, did not collapse the operation. Rather than dissolving, the apparatus evolved.\u201cState-aligned threat actors began utilizing out-of-band communication methods and alternative infrastructure, such as Starlink IP ranges, to bypass the degraded domestic grid,\u201d JP Castellanos, Director of Threat Intelligence at Binary Defense, tells The Cipher Brief.In simpler terms, Iranian hackers quickly shifted to alternative internet connections and encrypted communication channels that operate outside Iran\u2019s damaged infrastructure, allowing cyber operations to continue even as domestic networks faltered.Critical Infrastructure in the CrosshairsThe fallout from the February strikes has moved well past network probing. Iranian-linked hackers have successfully targeted and disrupted multiple U.S. oil, gas, and water sites \u2014 forcing some facilities to abandon automated systems entirely and operate manually, triggering financial losses, and, in some cases, deploying destructive wiper malware designed to erase data from victim networks. The IRGC\u2019s CEC-affiliated group CyberAv3ngers has been confirmed to be targeting programmable logic controllers across U.S. government facilities, water and wastewater systems, and energy sectors \u2014 exploiting internet-facing industrial devices to create openings not just for disruption but for modifications to operating parameters with direct physical consequences. The campaign represents an escalation: where earlier Iranian cyber operations tested access, these attacks are weaponizing it.Past operations attributed to IRGC-affiliated hackers include the 2011\u20132013 distributed denial-of-service attacks against major U.S. banks that disrupted online banking services for millions of customers. There was also the 2013 intrusion into the control systems of a small dam in New York, which demonstrated that Iranian hackers could potentially manipulate physical infrastructure.\u201cIranian cyber strategy has consistently prioritized the targeting of \u2018low-hanging fruit\u2019 within critical infrastructure sectors where high societal impact can be achieved with relatively low-sophistication techniques,\u201d Castellanos tells The Cipher Brief.Much of this activity now comes from pro-Iran and pro-Russian hacktivist groups working in coordination. The current wave of activity suggests that Iranian operators are positioning themselves for potential retaliatory strikes, while American defense agencies operate under constrained circumstances.\u201cThe Cybersecurity and Infrastructure Security Agency has been hampered by budget cuts, a significantly reduced workforce, and a lack of leadership over the last year,\u201d Dave Chronister, Founder of Parameter Security, tells The Cipher Brief. \u201cWhat makes it worse is that many of the remaining staff were effectively reassigned to support immigration enforcement operations rather than protecting critical infrastructure. That\u2019s a significant misalignment of mission at exactly the wrong moment.\u201dThe numbers now on record make that assessment concrete. CISA\u2019s FY2026 budget dropped to $2.4 billion, with 2,649 funded positions, down from $3.0 billion and over 4,000 positions the prior year. By January 2026, the agency had logged at least 998 departures, layoffs, and transfers since the administration took office. The Trump administration also moved to reprogram $144 million from CISA\u2019s 2025 budget to Immigration and Customs Enforcement operations.Now, a proposed FY2027 budget would cut an additional $707 million. During an ongoing DHS shutdown, the acting CISA director has publicly stated that the agency cannot conduct the outreach and preparatory work necessary to counter cyber threats.\u201cThe lapse of appropriations at CISA is impacting the depth and consistency of information sharing about Iranian cyber threats as well as coordinated planning for attacks that may occur,\u201d Bob Kolasky, Senior Vice President at Exiger and founding director of CISA\u2019s National Risk Management Center, tells The Cipher Brief.Soft Targets and Hard TruthsMany water utilities, hospitals, and local governments still run unpatched systems with known vulnerabilities \u2014 exactly the soft targets Iranian hackers seek.\u201cGenerally speaking, the most significant threat right now is what we call the n-day. These are known, but unpatched vulnerabilities, and Iranian threat actors are very aggressive at trying to exploit them,\u201d Chronister points out.The financial sector, despite its resources and experience defending against nation-state threats, remains vulnerable.\u201cOf all our critical sectors, the financial system is probably best positioned to weather an escalating Iranian threat, but \u2018best positioned\u2019 is not the same as immune,\u201d Chronister says. \u201cThe sectors that keep me up at night are healthcare, industrial operations such as energy utilities, water systems, manufacturing, and non-federal government agencies. Those are the soft spots, and adversaries know it.\u201dThe Stryker attack put the abstract into concrete terms. When Handala hit the Michigan-based medical technology giant on March 11, Maryland emergency responders lost access to the Lifenet system used to relay electrocardiogram data to hospitals, prompting a statewide alert that instructed EMS clinicians to switch to radio consultation.The attack wiped nearly 80,000 Windows devices, stole 50 terabytes of data, and materially impacted the company\u2019s first-quarter earnings. The FBI later seized two domains that Handala used to leak the stolen data. It is precisely the community-level harm the experts had forecast \u2014 now documented, not hypothetical.Kolasky\u2019s assessment aligns with this hierarchy of vulnerability.\u201cThe Iranian playbook seems to suggest taking advantage of vulnerabilities in weaker parts of critical infrastructure cyber defenses. These include under-resourced sectors such as water and wastewater, food and agriculture, government services and healthcare, as well as areas of outdated technology, which can include operational technology,\u201d he underscores.In a conflict scenario, Tehran aims to harm critical functions that affect daily life across American communities. Water systems are failing. Hospitals are losing access to patient records. Local government services are grinding to a halt. These scenarios represent asymmetric warfare designed to erode public confidence and create pressure on policymakers without crossing thresholds that might trigger an overwhelming military response.The Reach of Tehran\u2019s Digital OperationsThis geographic dispersion makes Iran\u2019s cyber apparatus resilient to kinetic strikes like the weekend bombing.\u201cCyber warfare depends far more on people than on high-end equipment, which means these operations can be dispersed across dozens of physical locations, down to a single operator working from a laptop,\u201d Chronister tells The Cipher Brief. \u201cWhile targeted strikes no doubt disrupt Iran\u2019s overall tempo, the distributed nature of cyber makes total elimination of the apparatus virtually impossible.\u201dThat assessment is no longer theoretical. During the twelve-day Israel-Iran conflict in June 2025, analysts from SecurityScorecard documented over 250,000 messages exchanged across 178 active Iranian proxy and hacktivist groups \u2014 with phishing campaigns, malware delivery, and data dumps timed precisely to kinetic strikes. Cyberattacks surged 700% within 48 hours of the opening salvos. When Iran\u2019s domestic internet was largely cut off, operators shifted to Starlink and VSAT services to maintain tempo. The lesson was already written before the current conflict began.Yet physical infrastructure still matters in the opening phases of conflict.\u201cPhysical destruction of infrastructure such as data centers, cell phone towers, satellite communication channels, radar systems \u2014 all these systems destroyed or degraded by kinetic strike are usually high priority targets in the start of any conflict, as it prevents Iranian command and control from communication to lower echelon units,\u201d Castellanos explains.Essentially, destroying the communications infrastructure temporarily prevents Iranian commanders from directing their cyber operators on the ground. Nonetheless, the impact is likely to be temporary rather than decisive. Using alternative networks and encrypted channels to bypass damaged infrastructure entirely, cyber operatives quickly adapt.\u201cEffective cyber campaigns depend on access to technical infrastructure for carrying out attacks, personnel, and some level of command and control,\u201d Kolasky asserts. \u201cUnited States and Israeli operations have the proven ability to degrade Iran\u2019s cyber capability and seem to have done so again. The question of how resilient the Iranian cyber warfare apparatus is remains an open one, but, thus far, it seems like we have limited Iran\u2019s cyber offensive ability and, in the short term, I would expect that will remain the case.\u201dIn simpler terms, the strikes have disrupted Iran\u2019s ability to coordinate large-scale cyber operations for now, but it remains unclear how quickly Tehran can rebuild its offensive capabilities.Meanwhile, Iranian operators have cultivated relationships with cybercriminal groups that provide technical services and operational cover. When Iranian-linked hackers targeted Albanian government networks in 2022, investigators traced the operation through multiple layers of contractors and intermediaries before establishing definitive state sponsorship.Right now, pro-Russian hacktivist groups such as NoName057(16), the Z-Pentest Alliance and Killnet have joined with pro-Iran groups targeting Israel and its Western allies, launching DDoS attacks against Israeli and United States financial services in coordination with Iranian goals. These attacks aim to disrupt online banking and payment systems, creating public frustration and economic uncertainty while demonstrating Iran\u2019s ability to strike back without firing a missile.Moreover, DieNet, a pro-Palestinian hacktivist group that emerged in March 2025 and has since claimed responsibility for DDoS attacks against U.S. energy, financial, healthcare, government, transit, and communications systems \u2014 deploying DNS amplification, TCP SYN floods, and NTP amplification in operations that intensified following the arrest of activist Mahmoud Khalil.\u201cThis international distribution of operations ensures that even if Iran is \u2018offline\u2019 domestically, its \u2018second front\u2019 in the cyber domain remains fully operational,\u201d Castellanos tells The Cipher Brief.Iran\u2019s malicious cyber activities are made more difficult by this operational model, which complicates attribution efforts. Iran uses proxy forces to advance its strategic objectives while maintaining an official distance from their activities as part of its regional strategy. In the cyber domain, this approach allows Iranian intelligence services to conduct operations that would be politically costly if directly attributed to Tehran.Since the February 28 strikes, Iranian-aligned groups have claimed numerous operations across the Middle East and beyond. Pro-Iran hacktivists have targeted energy infrastructure in Jordan, payment systems in Israel, and government portals across Gulf states. While many claims remain unverified, the volume and coordination of activity suggest a systematic campaign to demonstrate continued operational capability despite the degradation of Iran\u2019s domestic infrastructure.\u201cIt makes it very hard to identify them from a geolocation aspect, as well as identifying the fingerprint of the attack. It creates more resilience in these operations since there is no single point of infrastructure that you can attack,\u201d Chronister tells The Cipher Brief. \u201cIt also means that as Iran\u2019s leadership withers, and there is less coordination with their various cyber forces, these groups could act on their own initiative, which will make an already complex situation even worse.\u201dThe loss of centralized control cuts both ways for Iran. Cyber operations conducted by dispersed groups can withstand missile strikes, but rogue proxy groups operating independently may unintentionally escalate conflicts.Bombing a building does not stop hackers with laptops scattered across multiple countries, which highlights another fundamental challenge. Iranian cyber operatives can resume operations from new locations within hours, rendering traditional military strikes largely ineffective against digital threats.\u201cLike with proxy terrorist groups, Iran has the ability for a diffuse set of actors to work on behalf of the IRGC cause, but those actors are limited in the scale of what effects they can produce,\u201d he adds. \u201cThis diffusion will allow for a continued exploitation of vulnerable systems that I would expect to be targeted for propaganda victories, to shift public opinion, and to cause harm at the community level. This necessitates broad information sharing engagement across critical infrastructure for the United States cyber defense community.\u201dThe threat horizon extends well beyond the immediate conflict. Analysts are now flagging two upcoming high-profile moments on the U.S. calendar, the World Cup in June and the midterm elections in November, as likely priorities for Iranian cyber targeting. Security experts warn the tournament could see a 30 to 40 percent surge in fraud attempts, with Iranian-linked actors expected to focus specifically on airports, transportation systems, and critical infrastructure in host cities. Iran\u2019s track record of infiltrating U.S. systems ahead of strategic moments \u2014 elections, geopolitical flashpoints, major public events \u2014 suggests these will not be missed opportunities.The message is clear: Iran\u2019s distributed cyber army may lack the power to cripple America\u2019s infrastructure, but it has more than enough capability to disrupt daily life \u2014 and only coordinated defense can stop it.The Cipher Brief is committed to publishing a range of perspectives on national security issues submitted by deeply experienced national security professionals.
