A cyberattack on Twilio and a rise in hacks using text messages show the technology’s flaws.

Russia-linked cyber espionage attacks disrupted in US, UK
The Seaborgium hacking group has targeted more than 30 organizations since the start of the year, mainly in the U.S. and U.K., with some campaigns launched against groups in Ukraine and NATO members, Microsoft cybersecurity researchers said Monday. Seaborgium, which Microsoft's threat-intelligence center has tracked since 2017 and said originated in Russia, in some cases used Microsoft accounts, which the company has disabled. The group uses phishing email, fake LinkedIn profiles, and social engineering to penetrate systems over time. Details on how to recognize Seaborgium activity are here.
