By Joseph Menn and Jim Finkle PUNTA CANA, Dominican Republic (Reuters) – A computer security software firm has uncovered what it calls the first cyber espionage campaign believed to be started by a Spanish-speaking country, targeting government agencies, energy companies and activists in 31 countries. Dubbed “The Mask,” the campaign had operated undetected since 2007 and infected more than 380 targets before it stopped last week, Moscow-based Kaspersky Lab said on Monday. Kaspersky Lab said the discovery of The Mask suggests that more countries have become adept in Internet spying. This is the tip of the iceberg,” Costin Raiu, director of Kaspersky’s global research team, said in an interview on the sidelines of a conference sponsored by his company in the Dominican Republic.
