After Soleimani: The January 2020 US-Iran Cyber Alert Wave

Within hours of the 3 January 2020 strike that killed Iranian general Qasem Soleimani, security agencies on both sides of the Atlantic braced for cyber retaliation. On 6 January 2020 a U.S. federal website, the Federal Depository Library Program, was defaced with pro-Iran messaging and an image of a bloodied President Trump, claimed by a group calling itself Iran Silk Hat, while CISA and the FBI renewed warnings about possible Iranian attacks on critical infrastructure. This retrospective maps the verified incidents of that week, separates hype from evidence, and explains why agencies treated the moment as a genuine escalation trigger despite limited actual damage.

Ransomware at a Gas Compression Facility: CISA’s OT Alert

On 20 February 2020, CISA published AA20-030A, a joint advisory describing how ransomware had disrupted a natural gas compression facility: a phishing link let commodity ransomware spread from IT into the OT network, encrypting data historians and polling servers, severing HMI visibility, and leaving operators blind to real-time pressure and flow data for two days. The advisory became a reference model for oil and gas asset owners because it mapped, step by step, how a single email chained into loss of operational visibility without directly controlling pipeline equipment. This retrospective walks through the kill chain, the defensive gaps, and the guidance that followed.

Sisense Breach: CI Credentials, AWS Keys and a CISA Advisory

On April 24, 2024, CISA and the FBI advised every Sisense customer to rotate credentials after attackers compromised the BI vendor’s development environment — and by week’s end, Sisense-issued AWS keys were circulating publicly. This piece reconstructs the five-day arc from detection to contained, explains why business-intelligence platforms are credential funnels that turn vendor CI/CD breaches into customer incidents, and extracts the third-party-risk doctrine the episode left behind for every embedded-analytics supply chain.
