A Simple Bug Revealed Admins of Facebook Pages — Find Out How


Facebook Page admins are publicly displayed only if admins have chosen to feature their profiles.

However, there are some situations where you might want to contact a Facebook page admin or want to find out who is the owner of a Facebook page.

Egyptian security researcher Mohamed A. Baset has discovered a severe information disclosure vulnerability in Facebook that could have allowed anyone to expose Facebook page administrator profiles, which is otherwise not supposed to be public information.

Baset claimed to have discovered the vulnerability in less than 3 minutes without any kind of testing or proof of concepts, or any other type of time-consuming processes.

In a blog post, Baset said he found the vulnerability, which he described as a "logical error," after receiving an invitation to like a particular Facebook page on which he had previously liked a post.

Facebook has introduced a feature for page admins wherein they can send Facebook invitations to users asking them if they wished to like their page after liking a post, and a few days later, these interacted users may receive an email reminding them of the invitation.

After Baset received one such email invite, he simply opened "show original" drop-down menu option in email. Looking at the email's source code, he noticed that it included the page administrator's name, admin ID and other details.

The researcher then immediately reported the issue to the Facebook Security Team through its Bugcrowd bug bounty program. The company acknowledged the bug and awarded Baset $2,500 for his findings.

Though Facebook has now patched this information disclosure issue, people who have already received one such page invitation can still find out admin details from the invitation emails.
"We were able to verify that under some circumstances page invitations sent to non-friends would inadvertently reveal the name of the page admin which sent them," Facebook said. "We've address the root cause here, and future emails will not contain that information."

Chrome Web Browser Will Now Use 10% More RAM With Spectre Fix

A new security feature named ‘Site Isolation’ has been introduced for Google Chrome 67 which would nullify the effects of speculative execution side-channel attacks like Spectre. To put things to the perspective, Spectre is one of the two fundamental design flaws in the  modern processors, which allow programs to get access to the data for which it is not authorized. Malicious data can exploit this flaw to steal your password and other personal information. What is Site Isolation? The new Site Isolation feature introduced in Google Chrome 67 brings about a fundamental change to Chrome’s architecture. Now, Chrome has changed how its multi-process architecture worked and different tabs used different render processes. According to the new architecture, Chrome limits each renderer process to a single site. By this separation of processes, Google aims to prevent direct memory reading across different processes to safeguard users’ data. According to G...

Amazon, Reddit And Others Fail To Warn Us About Dumb Passwords

B elieve it or not, there is still a large number of people who use passwords such as “password,” “password123”, “[dog’s name]1” and others along the same lines. And in the era of sophisticated hacking, these passwords are not exactly “safe.” Before me, this is the first thing websites should inform you while setting up a password. But apparently, many big names are not doing enough to encourage non-terrible passwords, according to  the new research . Steve Furnell from the University of Plymouth has been keeping tabs on the websites like Amazon, Reddit, and Wikipedia for many years, carrying out similar assessments in 2007, 2011 and 2014. His 2018 survey examined practices of Google, Facebook, Wikipedia, Reddit, Yahoo, Amazon, Twitter, Instagram, Microsoft Live, and Netflix. The study concluded that Amazon had the worst performance among all the names. It nearly accepted every kind of password of any length. On the other hand, Yahoo and Wikip...
