How Russia weaponized America’s hacking tools to burn down the internet, and how Vermont lays vulnerable

By Timothy Page

In June 2017, the world witnessed what would become known as the most destructive cyberattack in history¹. NotPetya, initially mistaken for ransomware, was actually a sophisticated cyberweapon that caused over $10 billion in global damages and fundamentally changed how the world viewed cyber warfare².

The story begins not with criminal hackers, but with the United States National Security Agency (NSA). The agency had developed a collection of cyber exploitation tools, including a vulnerability in Microsoft Windows systems known as EternalBlue⁵. This exploit targeted the Server Message Block (SMB) protocol, allowing attackers to execute code remotely on vulnerable Windows machines without user interaction.

The NSA’s carefully guarded arsenal became public in April 2017 when a mysterious group calling themselves “The Shadow Brokers” leaked a trove of NSA hacking tools online¹. Among these tools was EternalBlue, which had been stockpiled by the NSA for intelligence operations rather than being disclosed to Microsoft for patching.

While Microsoft had actually patched the EternalBlue vulnerability in March 2017 (MS17-010)⁵, millions of systems worldwide remained unpatched, creating a massive attack surface. The leak essentially handed nation-state-level cyber capabilities to anyone willing to download and weaponize them.

Russia’s Sandworm Takes the Stage

Russian military intelligence unit GRU 74455, known in cybersecurity circles as “Sandworm,” quickly recognized the potential of the leaked NSA tools¹. This unit, operating under Russia’s Main Intelligence Directorate, had a history of conducting destructive cyberattacks, including the 2015 and 2016 attacks on Ukraine’s power grid¹.

Sandworm combined EternalBlue with other components to create what appeared to be ransomware but was actually designed for maximum destruction⁶. Unlike typical ransomware, NotPetya’s encryption was irreversible—there was no way to decrypt files even if victims paid the ransom. The ransom demand was merely a facade to disguise the attack’s true destructive intent.

The Ukraine Target

On June 27, 2017, NotPetya was deployed primarily through a compromised update to M.E.Doc, a popular Ukrainian accounting software used by most businesses in the country for tax reporting⁴. This delivery mechanism ensured that the malware would spread rapidly throughout Ukraine’s business infrastructure.

The attack was timed to coincide with the day before Ukrainian Constitution Day, maximizing psychological impact³. Within hours, NotPetya had infected thousands of Ukrainian systems, including:

• Government agencies
• Banks and financial institutions
• The Chernobyl nuclear power plant (forcing manual monitoring of radiation levels)
• Kiev’s airport and metro system
• Major Ukrainian media outlets

The choice of Ukraine as the primary target was no coincidence. Russia had been engaged in ongoing conflict with Ukraine since 2014, and cyberattacks had become a regular feature of this hybrid warfare campaign⁹.

Global Contagion

What made NotPetya particularly devastating was its use of multiple propagation methods⁷. Beyond EternalBlue, it also spread through:

• Lateral movement within networks using legitimate Windows administration tools
• Credential harvesting from infected machines
• Network scanning to identify additional targets

The malware was designed to spread indiscriminately once it gained a foothold, leading to massive collateral damage far beyond Ukraine’s borders. Major international companies were severely impacted:

• Maersk: The Danish shipping giant’s operations were paralyzed for weeks, costing an estimated $300 million¹⁰
• FedEx: TNT Express, FedEx’s European subsidiary, suffered prolonged disruptions
• Pharmaceutical companies: Merck’s manufacturing and research operations were significantly impacted
• NOTCO: The British advertising giant faced substantial operational disruptions

The Israeli Solution

As the attack spread globally, cybersecurity researchers and companies worldwide scrambled to understand and contain the threat. A crucial breakthrough came from Israeli cybersecurity researchers who were among the first to recognize that NotPetya was not actually ransomware but a destructive wiper masquerading as one⁸.

Israeli cybersecurity firms, including Check Point and CyberArk, played significant roles in analyzing the malware’s behavior and developing countermeasures⁸. Their research revealed that the malware’s encryption routine was fundamentally flawed in a way that suggested intentional irreversibility—a key indicator that this was designed for destruction rather than financial gain.

The Israeli cybersecurity community’s rapid response and analysis helped organizations worldwide understand the true nature of the threat and implement appropriate defensive measures. Their work was instrumental in preventing even more widespread damage as they shared indicators of compromise and mitigation strategies with the global cybersecurity community.

Attribution and Aftermath

In February 2018, the U.S., UK, and other allies formally attributed NotPetya to Russia’s GRU, specifically the Sandworm unit³⁹. The U.S. government called it “the most destructive and costly cyberattack in history.” In 2020, six GRU officers were indicted by the U.S. Department of Justice for their role in the attack².

The total economic damage from NotPetya is estimated to exceed $10 billion globally, making it far more costly than any previous cyberattack¹. The attack demonstrated how quickly a targeted cyber operation could spiral into global catastrophe in our interconnected world.

Speculative Impact on Vermont

Based on Vermont’s current infrastructure and recent cybersecurity assessments, a NotPetya-style attack would pose severe risks to the state’s interconnected systems:

Critical Infrastructure Exposure: Vermont’s electrical grid faces increasing cyber threats, as highlighted in the 2023 Vermont State Hazard Mitigation Plan¹¹. The state’s utilities, including Green Mountain Power (serving 265,000 customers) and Vermont Electric Cooperative, have invested heavily in grid modernization but remain vulnerable to sophisticated attacks. A 2024 Department of Homeland Security assessment noted that Vermont’s power grid interconnections with Hydro-Quebec and ISO New England create additional attack vectors that could amplify disruption¹².

Healthcare System Vulnerability: Vermont’s healthcare sector has already experienced significant cyber incidents. In 2020, the University of Vermont Health Network suffered a cyberattack that disrupted operations for weeks¹⁹. The state’s 14 critical access hospitals and aging population (Vermont has the second-oldest population in the U.S. as of 2023) make healthcare disruptions particularly dangerous. The Vermont Department of Health’s 2024 cybersecurity assessment identified healthcare as the state’s most vulnerable critical sector¹³.

Economic Infrastructure: Vermont’s $37.8 billion economy (2023 GDP figures)¹⁸ relies heavily on interconnected digital systems. The state’s 2024 Economic Development Strategic Plan identified cybersecurity as a key business risk, noting that 78% of Vermont businesses use cloud-based accounting and management systems¹⁴. The Vermont Agency of Commerce and Community Development reported in 2023 that cyber incidents cost Vermont businesses an average of $2.1 million per incident²⁰.

State Government Digital Vulnerability: Vermont has experienced multiple government cyber incidents, including a 2021 attack on the Vermont Department of Motor Vehicles and a 2022 breach of the Agency of Human Services. The state’s 2024 IT Strategic Plan acknowledged that Vermont’s decentralized IT infrastructure across 80+ agencies creates multiple attack surfaces¹⁵.

Regional Interconnectedness: Vermont’s participation in the New England power grid and financial networks means local attacks could cascade regionally. The 2024 New England States Committee on Electricity report noted that cyber vulnerabilities in any member state could affect the entire regional grid serving 14 million people¹⁶.

Climate Vulnerability Multiplier: Vermont’s increasing reliance on electric heating due to climate initiatives (the state aims for 90% renewable energy by 2050) makes power grid attacks potentially life-threatening during winter months when temperatures regularly drop below -10°F.

Based on recent economic analyses and Vermont’s critical infrastructure dependencies, cybersecurity experts estimate a NotPetya-scale attack could cause $800 million to $1.5 billion in direct economic damage to Vermont, representing 2-4% of the state’s GDP. The Vermont Emergency Management Agency’s 2024 risk assessment classified a major cyberattack as the third-highest threat to the state, after severe weather and flooding¹⁷.

Lessons Learned

NotPetya fundamentally changed cybersecurity thinking in several ways:

1. Weaponization of Legitimate Tools: The attack showed how quickly leaked government cyber tools could be repurposed for mass destruction
2. Collateral Damage: It demonstrated that targeted cyberattacks could have massive unintended global consequences
3. Attribution Challenges: The complexity of modern cyberattacks makes rapid attribution difficult, allowing attacks to spread before effective countermeasures are implemented
4. Economic Vulnerability: The attack revealed how deeply embedded digital systems are in modern economies and how quickly cyberattacks can cause physical-world damage

NotPetya remains a watershed moment in cybersecurity history, illustrating the thin line between cyber espionage tools and weapons of mass disruption.
