Motherboard reported Sunday that a former member of a hacker group notorious for taking over social media accounts was arrested earlier this month, citing law enforcement and members of the group.

Driving the news: According to Motherboard, authorities arrested a onetime member of "Chuckling Squad," a notorious group that, among other mischief, took over Twitter CEO Jack Dorsey's Twitter account in August. That hacker, an unnamed minor, had previously been kicked out of the group

How it works: Chuckling Squad is a prolific user of SIM swapping, a technique through which hackers cajole cellphone companies to transfer a victim's phone number to phones that the hacker controls. From there, SIM swappers can use their access to a supposedly secure phone number to reset account passwords or otherwise tamper with accounts.

The big picture: The lesson from groups like Chuckle Squad and others using this mode of account takeover is that for people who require the most security and attach cell numbers to their accounts, it's important to turn on whatever added protections a mobile provider has to prevent SIM swapping. Those often including adding a passcode to move the phone number or to only allow that service to be done in person.

Driving the news: J&J is already in the process of shipping 3.9 million doses this week, just days after the FDA issued an emergency use authorization for the one-shot vaccine. Gorsky said he expects vaccines to be administered to Americans "literally within the next 24 to 48 hours."

President Biden expressed support for a union vote by Amazon warehouse workers in Alabama in a two-minute video posted on Twitter Sunday, though he did not name the tech giant specifically.

Why it matters: A vote by workers at the Bessemer, Ala., warehouse to join the Retail, Wholesale and Department Store Union would make the facility the first Amazon warehouse to unionize in the U.S., per NPR. The election will run through March 29.
