A maze of gas pipelines.

A US-based natural gas facility shut down operations for two days after sustaining a ransomware infection that prevented personnel from receiving crucial real-time operational data from control and communication equipment, the Department of Homeland Security said on Tuesday.

Tuesday’s advisory from the DHS’ Cybersecurity and Infrastructure Security Agency, or CISA, didn’t identify the site except to say that it was a natural gas-compression facility. Such sites typically use turbines, motors, and engines to compress natural gas so it can be safely moved through pipelines.

The attack started with a malicious link in a phishing email that allowed attackers to pivot

When your family opened up that brand-new computer when you were a kid, you didn’t think of all of the third-party work that made typing in that first BASIC program possible. There once was a time when we didn’t have to worry about which companies produced all the bits of licensed software or hardware that underpinned our computing experience. But recent malware attacks and

Anatomy of a dumb spear-phish: Hitting librarians up for Zelle, CashApp cash

Here’s a clue for would-be Internet financial scammers: do not target librarians. They will catch on fast, and you will have wasted your time.

Yesterday, the outgoing chair of the Young Adult Library Services Association’s Alex Awards Committee (and my wife) Paula Gallagher got a very odd email that purported to be from a colleague within her library system who is a member of YALSA’s board. The email asked, “Are you available to complete an assignment on behalf of the Board, And get reimbursed? Kindly advise.”

There were a few things off about the email. First of all, while

Passengers use mobile stairs to exit and jet plane at night.

The Diamond Princess cruise ship where the passengers were evacuated from, docked at the Japanese city of Yokohama, is believed to be the highest concentration of novel coronavirus cases outside of China, where the outbreak began.

Fourteen Americans tested positive for carrying the new coronavirus just as they began their return to the United States from Yokohama, Japan, where they had been trapped aboard the luxury cruise ship Diamond Princess

Despite its distance from the Sun, the asteroid belt will disintegrate as it expands.

We tend to view the bodies of the Solar System as creations of gravity, which pulled their parts together and holds them in place as they orbit. But as we saw with ideas about the formation of Arrokoth, there are lots of situations where gravity is essentially a constant for long periods of time. And given enough of that time, relatively small forces like friction from sparse gas clouds or pressure from the light of the Sun can add up and create dramatic changes. In

Migrating geese fly in a V shape.

Even though it was, in most ways, identical to the present planet, the Earth still looked very different at the bottom of the last ice age 20,000 years ago. The globe was around 4°C cooler on average, and ice sheets covered large portions of the Northern Hemisphere, including Canada and Scandinavia. One thing you might wonder, given how much of the planet was barely habitable, is what migratory species did.

Given the loss of all that habitat to mile-thick glacial ice and a reduced winter-summer contrast courtesy of Earth’s orbital cycles, some researchers have hypothesized that bird migration wasn’t
