This is aimed more at industries than individuals, but it's still good to know: Octo Tempest cybercriminal group is "a growing concern"—Microsoft

The newsletter from Malwarebytes this week has some grim information about cybercriminals.

Octo Tempest is believed to be a group of native English speaking cybercriminals that uses social engineering campaigns to compromise organizations all over the world.

Initially the group made a name for itself by SIM swapping. SIM swapping, also known as SIM jacking, is the act of illegally taking over a target's cell phone number. This can be done in a number of ways, but the most common ones involve social engineering attacks on the victim's carrier.

In a security blog about Octo Tempest Microsoft states:

“Octo Tempest monetized their intrusions in 2022 by selling SIM swaps to other criminals and performing account takeovers of high-net-worth individuals to steal their cryptocurrency.”

Since then the group has expanded its range of activities to include targeting organizations providing cable telecommunications, email, and tech services, and partnering with the ALPHV/BlackCat ransomware group.

In our monthly ransomware reviews you will typically see ALPHV as the world's third most used ransomware-as-a-service (RaaS).
