Privacy issues on Twitter and Instagram

12. August 2019

Both, Twitter and Instagram admitted in the last week that they had some privacy issues regarding the personal data of users in connection with external advertising companies.

Twitter published a statement explaining that the setting choices the user made in regards to ads on Twitter, ecspecially regarding data sharing, were not followed always. Twitter admitted that the setting choices not have worked as intended. The consequence of which is that on the one hand maybe data was shared with advertising companies in case the user clicked or viewed an advertisement. On the other hand it is possible that personalized ads have been shown to the user based on inferences. Both things could have happened even if no permission was given.

The statement also states that the problems were fixed on August 5, 2019 and no personal data like passwords or email accounts were affected. At the moment Twitter is still investigating how many and which users were concerned.

According to a report on businessinsider Instagram had to admit that the trusted partner Hyp3r tracked millions of users’ location data, secretly saved their stories and flout its rules.  Hyp3r, a startup from San Francisco is spezialized on location related advertising and evaluated millions of users’ public stories. The CEO of Hyp3r published a note on the company’s website and contradicts the comparisons with Cambridge Analytica and says that no prohibited practives were used. Privacy is a major and important concern for the company. Whether this is the case can only be left open at this point. Be that as it may, for European users of the platform there is no known legal basis for such an approach.

Nonetheless, Instagram’s careless privacy and data security mechanisms enabled this approach. Even though Instagram ended the cooperation with Hyp3r and stated that they changed the platform to protect the users, the problems of the Facebook-owned app regarding the protection of users personal data are still there.

Twitter shared location data on iOS devices

15. May 2019

Twitter recently published a statement admitting that the app shared location data on iOS devices even if the user had not turned on the “precise location” feature.

The problem appeared in cases in which a user used more than one Twitter account on the same iOS device. If he or she had opted into the “precise location” feature for one account it was also turned on when using another account, even if the user had not opted into using the feature on this account. The information on the real-time location was then passed on to trusted partners of Twitter. However, through technical measures, only the postcode or an area of five square kilometres was passed on to the partners. Twitter accounts or other “Unique Account IDs”, which reveal the identity of the user, were allegedly not transmitted.

According to Twitter’s statement, they have fixed the problem and informed the affected users: “We’re very sorry this happened. We recognize and appreciate the trust you place in us and are committed to earning that trust every day”.

Reuters: U.S. companies ask Trump to support encryption

17. November 2016

This week, Reuters reported that U.S. internet companies, such as Facebook and Amazon have sent a detailied letter including a list of their policiy priorities to President-elect Donald Trump. Among the topics of these policies are encryption, immigration reform and maintaining liability protections from user’s content.

The mentioned letter was sent by the so called Internet Association, which is a group of 40 members, also including Alphabet’s Google, Uber and Twitter. The letter tries to repair the relationship between the internet giants and Trump due to the fact that he was almost universally disliked during the presidential campaign.

The president of the Internet Association, Michael Beckermann signed the letter talking about “The internet industry looks forward to engaging in an open and productive dialogue”. Furthermore, Beckerman issued a statement  syaing that the internet industry looked forward to working closely with Trump and lawmakers in Congress in order to “cement the internet’s role as a driver of economic and social progress for future generations.”

The letter describes some of the policies which go along with Trump’s prior statements, for example easing the regulation on the sharing economy and applying pressure on Europe to not erect too many barriers that restrict U.S. internet companies from growing in that market.

However, other topics are likely to be opposed with Trump’s campaign as he offered numerous broadsides against the tech sector.

 

 

Twitter: 32 million accounts may have been hacked and leaked

9. June 2016

Hackers may have used malware in order to gain more than 32 million Twitter login-data that are now presumable being sold on the dark web. However, a Twitter spokesman said that “We are confident that these usernames and credentials were not obtained by a Twitter data breach – our systems have not been breached. In fact, we’ve been working to help keep accounts protected by checking our data against what’s been shared from recent other password leaks.”

LeakedSource, a site with a search engine of leaked login credentials, says that the respected data of Twitter contains 32,888,300 records consisting of email addresses, usernames and passwords.

Due to the provided information included in the respected data, for example the fact that passwords are displayed without encryption, LeakedSource stated that the data was collected by malware that has infected internet browsers rather than stolen directly from Twitter. In order to verify that the leaked data is valid, LeakedSource asked 15 users to verify their passwords. All of them confirmed that the passwords were correct.

However, Twitter stated that the hacking of accounts belonging to celebrities was due to the re-use of passwords that were leaked in the LinkedIn and Myspace breaches. A spokesman said that “A number of other online services have seen millions of passwords stolen in the past several weeks. We recommend people use a unique, strong password for Twitter”.

Whether or not the leaked data is valid, it is recommended to change passwords, not only when using the same password for several accounts.

Twitter blocks U.S. Intelligence Agencies from Dataminr service

10. May 2016

Dataminr is used as a tool that analyzes and traces social media posts and notifies users about breaking news in real time, such as the terror attack in Brussel´s airport in March. This analysis is carried out by using key words, patterns, or geotags.

Twitter, that owns 5% of Dataminr, has now blocked U.S. intelligence services from its Dataminr service, in order not to appear to support the surveillance activities of the U.S. Intelligence services.

Dataminr services where used by the American Government in 2013 to detect any risks on the inauguration of U.S. President Obama´s second term. However, it is not clear how Dataminr provided this service to the U.S. Intelligence services, as Twitter´s privacy policy prohibits selling its data to governmental agencies.
