Two kinetic incidents of importance surfaced over the weekend. Iran's Natanz nuclear facility sustained an apparently "deliberately planned" explosion and power outage Sunday, according to the New York Times. While decrying the outage as "sabotage" and an "act of terror," Iranian authorities did not immediately assign blame. Israeli media, however, unofficially attributed the incident to an Israeli cyberattack. The Wall Street Journal reports that Tehran this morning did the same, and promised "revenge against the Zionists."
The other incident involved the arrest, Thursday, of a Texas man whom the FBI says attempted to buy explosives from an undercover FBI employee, allegedly intending to blow up an Amazon Web Services facility in Virginia. BleepingComputer says that the Bureau identified the man's plans from posts he'd made in January on the MyMilitia site. A third-party also tipped off the FBI that the suspect, one Seth Aaron Pendley, had communicated in a Signal message an interest in buying C-4, the Record reports.
