that’s a bug in the Android app, and Twitter made it possible to have the names of the accounts will have to figure this out, I found a beveiligingsonderzoeker Ibrahim Balic. He was able to have a huge list of phone numbers uploaded via the Twitter app, so the user accounts have been exposed, ” he explained to the American news website TechCrunch.
which way did Balic 17 million phone numbers to link to their Twitter account. Twitter is blocking it on the 20th of december, so that the researcher could not proceed with his practice.
finally, The researcher had the numbers, not in their own hands, but be used in any combination of the digits of a number system. Thus, the error is also the possibility of using a business and private number, to identify the source of specific Twitter users.
It is not clear whether the bug is due to others, on a large scale is to be applied or have been abused. In the opposite, TechCrunch is not on the findings and respond to it.
