1. β What Happened
In May 2021, Colonial Pipeline β a major U.S. fuel pipeline operator β was hit by a ransomware attack that forced it to shut down operations for five days. This led to fuel shortages, panic buying, and skyrocketing gas prices across the East Coast. The attackers, a Russian-speaking group called DarkSide, gained access through a single compromised VPN password.
2. π οΈ Technical Challenge
Colonial had an unused VPN account that lacked multi-factor authentication (MFA). Hackers found the leaked credentials on the dark web, logged in, and deployed ransomware that encrypted key systems. The attack wasnβt technically advanced β it was the result of poor credential hygiene and lack of basic protections.
3. π§© How It Was Resolved
Colonial paid a $4.4 million ransom (part of which was later recovered by the FBI). Recovery took days, with manual pipeline operations and system rebuilds. The event became a national security issue, prompting new cybersecurity regulations for critical infrastructure.
4. π‘οΈ What You Can Do as an SMB
- Enforce MFA everywhere β even on unused or internal accounts.
- Audit credentials regularly β especially those stored in old systems or leaked on the dark web.
- Implement zero-trust access β so one account canβt open the entire network.
- Have an offline backup and incident playbook β ransomware can lock you out completely.
