Shares of Apple Inc. (Nasdaq: AAPL) dipped 1.1% on news its customers were the subject of a cyber attack over the weekend.

Ransomware encrypts data on infected machines and then demands that users pay ransoms in digital currencies so they can obtain a key to unlock their data. AAPL’s downturn weighed on the Nasdaq, which declined eight points on the day.
