AT&T Inc. said thieves made off with a half-year’s worth of calling and text data from virtually its entire wireless user base, the widest-ranging breach yet in a campaign that’s ensnared as many as 165 customers of software seller Snowflake Inc.

Snowflake said in June that hackers had launched a “targeted” effort against its clients, and has blamed its customers for failing to take adequate steps to protect their data. But the data analysis software company is suffering “reputational damage” from the hack, wrote Frank G. Louthan, an analyst at Raymond James.
