In a concerning development for the agriculture and food distribution sector, the ransomware group known as Rhysida has claimed a fresh victim: Mountain View Mushrooms. This incident, first reported on May 9, 2025, by the ThreatMon Ransomware Monitoring team, continues a disturbing pattern of cyberattacks targeting mid-sized enterprises with critical supply chain roles.
Mountain View Mushrooms, a recognized player in North America’s food production ecosystem, now finds itself in the crosshairs of a cyber extortion campaign. This attack underscores how ransomware groups like Rhysida continue to pivot from attacking purely financial institutions to hitting industrial, agricultural, and logistical firms — especially those with lower cybersecurity budgets and high uptime requirements.
With this breach now public, a new layer of vulnerability emerges for both food safety and national supply chain continuity. Here’s what we know — and what we at Undercode have uncovered by digging deeper.
the Rhysida Ransomware Attack on Mountain View Mushrooms
Date of Incident: May 9, 2025, reported at 11:26 AM UTC+3.
Threat Actor: Rhysida, a ransomware group known for targeting sectors with minimal cybersecurity preparedness.
Victim: Mountain View Mushrooms — a U.S.-based mushroom farming and distribution company.
Source: ThreatMon Threat Intelligence Team, which monitors ransomware activity on the dark web.
Platform Used: The disclosure was made on X (formerly Twitter) by @TMRansomMon.
Evidence of Compromise: Rhysida has added the company to its victim list on their leak site, typically indicating either a data breach or an ongoing extortion attempt.
Potential Impact: Disruption to food supply, operational downtime, financial loss, potential regulatory scrutiny, and reputational damage.
Rhysida’s Strategy: This group often employs double extortion — encrypting files and threatening to leak data if a ransom isn’t paid.
Detection Channel: Intelligence gathered through dark web tracking, primarily via ThreatMon’s monitoring infrastructure.
Historical Context: Rhysida is a relatively recent but aggressive group, believed to operate in overlapping circles with other ransomware-as-a-service (RaaS) affiliates.
Victim Profile Trend: Rhysida has been targeting companies with infrastructure dependencies and weak digital defenses, including educational institutions, logistics firms, and now agricultural entities.
What Undercode Say:
The attack on Mountain View Mushrooms marks a strategic evolution in how ransomware groups are choosing their targets. The agricultural sector, while not traditionally a high-tech industry, has become increasingly digital — integrating IoT devices, automated growing systems, and centralized inventory software. This convergence of tech and farming creates a fertile attack surface.
Why this matters:
Cyber-Physical Systems Vulnerability: Mushroom farms like Mountain View depend on climate-controlled environments powered by interconnected digital systems. A ransomware attack can lock operators out of these controls, potentially destroying entire harvests.
Critical Infrastructure Dependency: While not typically classified as critical infrastructure, agriculture directly affects food supply chains. An attack here has cascading effects, from empty supermarket shelves to restaurant shortages.
Operational Impact: With ransomware, it’s not just about stolen data. It’s about being unable to access vital business functions — order fulfillment, financial transactions, and crop monitoring.
Strategic Exploitation: Rhysida appears to be leveraging a tactic of attacking businesses that can’t afford to wait days or weeks to restore from backups, pressuring them to pay quickly.
Double Extortion Tactics: Based on Rhysida’s history, it’s likely that sensitive internal documents — financials, supplier contacts, employee data — may be leaked unless a ransom is paid.
Regulatory Risks: Should the breach involve personal data, Mountain View Mushrooms may face scrutiny from regulators under data protection laws like CCPA or GDPR (if any EU data is involved).
Insurance Gap: Many mid-sized agricultural firms lack comprehensive cyber insurance, making ransom payment more likely and recovery harder.
Economic Perspective: In 2023, the average ransom demand exceeded \$1.5 million. For an agricultural business, this could wipe out seasonal profits or force layoffs.
Industry Implications:
For agriculture: There needs to be a sector-wide reckoning with digital risk. As precision agriculture becomes more mainstream, cybersecurity must become part of farming strategy.
For cybersecurity: Monitoring dark web chatter and leak sites has never been more important. Threat intelligence providers like ThreatMon are critical for proactive defense.
For policy makers: Attacks on food producers could justify reclassifying agricultural tech as part of national critical infrastructure.
Rhysida’s Positioning:
Rhysida is not just another RaaS outfit. Their targeting indicates knowledge of supply chain bottlenecks, making them a real threat to industries that rely on just-in-time logistics.
Undercode’s Takeaway: The agricultural sector must wake up. Cybersecurity is no longer just an IT department concern — it’s a farm-to-fork issue. Threat actors are adapting. So should defenders.
Fact Checker Results:
✔️ Confirmed: Mountain View Mushrooms was listed on Rhysida’s leak site.
✔️ Verified Source: ThreatMon is a known cybersecurity monitoring firm with a history of accurate reporting.
✔️ Pattern Matches: The tactics align with previous Rhysida operations (double extortion, timing around operational dependencies).
Prediction:
We anticipate that more ransomware attacks will target agricultural and food production companies through 2025. With increasing digitization in farming operations and ongoing global food supply stress, attackers will continue exploiting sectors where digital disruption can yield maximum leverage. This also means that insurance providers, regulators, and even national defense agencies may begin recognizing these vulnerabilities as matters of food security and economic stability. Expect a surge in both attacks and reactive cybersecurity investment across farming and distribution sectors.
