As Facebook CEO Mark Zuckerberg discussed about making his platform more secure, a bug in Facebook Messenger allowed websites to gain access to users’ data, including who they have been chatting with, say researchers.

Now fixed by Facebook, the vulnerability in the web version of Messenger allowed any website to expose who you have been messaging, revealed Ron Masas, researcher with cyber security company Imperva, in a blog post late on Thursday.

The researcher reported the vulnerability to Facebook under their responsible disclosure programme and the social media platform mitigated the issue.

In November 2018, Masas and his team discovered a Facebook bug that allowed websites to extract data from users’ profiles via cross-site frame leakage (CSFL) which is known as a side-channel attack performed on an end user’s web browser.

In a bid to prevent foreign interference into elections, facebook has also begun labelling all political and issue ads in the us -- including a "paid for by" disclosure from the advertiser at the top of the advertisement.

“Browser-based side-channel attacks are still an overlooked subject. While big players like Facebook and Google are catching up, most of the industry is still unaware,” wrote Masas.

Facebook Messenger has over 1.3 billion users globally.

Zuckerberg on Thursday said he is working to make Facebook “privacy-focused” like WhatsApp.

The “privacy-focused platform” will be built around principles like private interactions, encryption, reducing permanence, safety and interoperability. (IANS)

Researchers have found out that the number of negative posts on Facebook business pages vastly outweigh the positive ones by a ratio of nearly two to one.

There are more than 60 million business pages on Facebook and that number is from 2017 and with those pages come scores of positive and negative posts generated by Facebook users.

The researchers have seen that companies have very little control over what customers post, and negative ones can severely damage brands.

“We also found positive and negative posts get more likes than neutral ones, but negative posts get the most comments,” said study researcher Mochen Yang, Professor at the University of Minnesota.

“Complaints about social issues receive more likes, but fewer comments, than complaints about quality or money issues,” Yang added.

The study, published in the journal Information Systems Research, analyses this user-generated content to understand the impact of what users post and how it impacts the brand.

Engagements depend not only on the type of post, but also in the specific ways the post is positive or negative.

The study looked at data from 12,000 posts from 41 Fortune 500 companies in six industries in 2012.

“Though increased engagement has been linked to increases in brand loyalty, purchase expenditures, and profitability, companies should carefully consider whether Facebook business pages are an appropriate venue to interact with customers,” Yang added. (IANS)
