Twitter has disclosed a 'Data Security Incident' that caused the billing information for Twitter advertisers to be stored in the browser's cache. This bug would have allowed other users on the computer to see this data.
In February, Twitter
disclosed that one of their APIs could have been abused by ‘nation state' actors to match usernames of Twitter accounts against phone numbers.
Now, this security incident has put the spotlight on the company again.
Today, Twitter has begun emailing business customers who utilize Twitter Ads and Analytics Manager about a 'Data Security Incident' that incorrectly stored a Twitter advertiser's billing information in the browser cache.
