Twitter discovered a vulnerability that was causing the platform users' information to be incorrectly stored in the Firefox browser cache. The social network led by Jack Dorsey warned that the data and messages of those who access Twitter through the Mozilla browser, especially on public or shared computers, may have been stored in the cache even after users leave.
In an alert publication, the company explained that the Mozilla browser retains information such as the Twitter data file or all images or videos received via direct messages in the cache for 7 days, deleting them after that period. The problem does not affect social network users who use Google Chrome or Apple's Safari, for example.
In a situation where the computer suffers a computer attack, the malware installed on the equipment could, for example, steal the data in question. Remember that when faced with the presence of sensitive information, such as names, identification numbers or bank accounts, cybercriminals may use them in fraudulent schemes or sell them in black online markets.
Twitter regretted what happened and said it had already changed the way information is stored in Firefox so as not to repeat the incident. For users at risk, the company recommended cleaning the data in the browser cache, as well as increased attention when it comes to personal information that is on shared or public computers.
