TikTok came back online after Donald Trump promised to delay a law banning it, but its service providers have taken different stances on the ban.

The president-elect said he will issue an executive order Monday to delay the ban while he brokers a sale. The app returned on web and mobile, but is not available in Apple and Google's stores.

The U.S. Treasury Department on Friday imposed sanctions on alleged hacker Yin Kecheng and cybersecurity company Sichuan Juxinhe Network Technology Co., accusing both of being involved in a series of hacks against American telecom companies.
