Twitter admits ‘bad actors’ exploited phone number matching feature

The enterprise states that just after suspending the first set of fake accounts exploiting the flaw — presumably Balic’s, who produced hundreds of sock puppet accounts for his investigation — it located much more. People further accounts have been positioned from a broad vary of countries, but most of them have been from Iran, Israel and Malaysia, based mostly on the IP addresses Twitter traced.

“It is feasible that some of these IP addresses may well have ties to condition-sponsored actors,” its announcement reads. “We are disclosing this out of an abundance of warning and as a make any difference of basic principle.”

Despite the fact that the flaw authorized poor actors to look up millions of phone numbers of persons they don’t know, buyers who don’t have the “Allow persons who have your phone amount find you on Twitter” environment enabled were not influenced. Even more, Twitter suspended all the offending accounts it located and modified its API to reduce poor actors from exploiting the amount matching aspect going forward.
