Chinese microblogging giant Sina Weibo has now made it to the news owing to a security incident. Weibo suffered a data breach exposing 538 million records. What’s concerning is that the stolen data is now for sale on the dark web.

Sina Weibo Data Breach

Reportedly, Chinese site Sina Weibo has faced a data breach exposing millions of records. According to reports, around 538 million users’ information are circulating online that hackers have stolen from Weibo.

The news surfaced online after Wei Xingguo (Yun Shu), CTO Moresec, posted about it on Weibo. Wei even alleged that his own contact number was leaked along with other’s data on March 19.

Later, Weibo officials also confirmed the breach, however, they did not relate it to an attack on their systems. According to Luo Shiyao, Security Director at Weibo, the data surfaced online due to a ‘dictionary attack’, perhaps dated back to 2018.

Phone numbers were leaked due to brute-force matching in 2019 and other personal information was crawled on the Internet… When we found the security vulnerability, we took measures to fix it.

Though, Pandaily reported that both Wei’s and Luo’s posts were deleted later.

Hacked Data Sold Online

While the exact timings of the breach remain unconfirmed, there certainly is a breach that made users’ data public.

Following Wei’s post, users also revealed in the comment section that they found explicit details of the users on the dark web. As reported, around 172 million records leaked on darknet had basic account information and put on sale for 0.177 bitcoins.

According to Phala Network, the breach of information seems true as they could also buy the data through a Telegram group. As stated in their post (translated) the author could buy his own data.

The author personally tested, 0.358 ETH = 260 points, 10 points can be used for a general query, which is equivalent to 0.0138 ETH once, which is about 10 yuan once…
I have learned through the mobile phone number query that I have exposed my multiple passwords and real names!

Until the time of writing this article, there aren’t many details regarding the breach, nor Weibo has put up any public disclosure or denial of the incident. Yet, reports hint that the company is presently investigating the matter. So, let’s wait for more details from the official sources.

Analytics

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
