‘Dangerous Stuff’: Hackers Tried to Poison Water Supply of Florida Town (The New York Times, Feb 09 2021)

SonicWall Zero-Day (Schneier on Security, Feb 08 2021)
“Hackers are exploiting zero-day in SonicWall:

In an email, an NCC Group spokeswoman wrote: “Our team has observed signs of an attempted exploitation of a vulnerabilitythat affects the SonicWall SMA 100 series devices. We are working closely with SonicWall to investigate this in more depth.”

In Monday’s update, SonicWall representatives said the company’s engineering team confirmed that the submission by NCC Group included a “critical zero-day” in the SMA 100 series 10.x code.”

What’s most interesting about the Florida water system hack? That we heard about it at all. (Krebs on Security, Feb 10 2021)
“Stories about computer security tend to go viral when they bridge the vast divide between geeks and luddites, and this week’s news about a hacker who tried to poison a Florida town’s water supply was understandably front-page material. But for security nerds who’ve been warning about this sort of thing for ages, the most surprising aspect of the incident seems to be that we learned about it at all.”

Filter Out the Noise
Since I started this curated security news in June 2017, I’ve clipped ~17,000 articles and narrowed them down into the best 20 per day & best 15 per week. This is my favorite way to cut through all the security marketing and hype. If you’re enjoying it, tell a friend. If you hate it, tell an enemy.
Thanks! – Lucas Samaras
