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.

After a year-long delay, the Olympics finally got underway Friday as tennis star Naomi Osaka, who is competing for Japan, lit the cauldron, formally kicking off the Tokyo Games.

The big picture: Friday's opening ceremony looked, like many things over the last year, different than normal — multicolored seats replaced cheering fans, masks were a central part of the athletes' uniforms and a subdued, somber tone marked the occasion.

The Chinese government imposed sanctions on Monday against six Americans, including former Commerce Secretary Wilbur Ross, in response to an advisory from the Biden administration warning businesses of the increased risks of operating in Hong Kong.

Why it matters: It's the latest example of China responding furiously to U.S. attempts to shed light on human rights abuses in places like Hong Kong, Xinjiang and Tibet, which Chinese officials routinely condemn as "interference" in domestic affairs.

Cleveland Indians change name to "Guardians"

The Cleveland Indians baseball team announced Friday that it will change its name to the "Guardians," following years of activism and protests against a moniker considered offensive by many Native Americans.

Why it matters: It's the first time the team will change its name since 1915, a move that comes in the wake of the nationwide racial reckoning that began with the murder of George Floyd.
