Flaw in LinkedIn AutoFill Plugin Lets Third-Party Sites Steal Your Data

Flaw in LinkedIn AutoFill Plugin Lets Third-Party Sites Steal Your Data

April 21, 2018Swati Khandelwal
Not just Facebook , a new vulnerability discovered in Linkedin's popular AutoFill functionality found leaking its users' sensitive information to third party websites without the user even knowing about it. LinkedIn provides an AutoFill plugin for a long time that other websites can use to let LinkedIn users quickly fill in profile data, including their full name, phone number, email address, ZIP code, company and job title, with a single click. In general, the AutoFill button only works on specifically "whitelisted websites," but 18-year-old security researcher Jack Cable of Lightning Security said it is not just the case. Cable discovered that the feature was plagued with a simple yet important security vulnerability that potentially enabled any website (scrapers) secretly harvest user profile data and the user would not even realize of the event. A legitimate website would likely place a AutoFill button near the fields the button can fill, but accordin

A Russian man accused of hacking LinkedIn , Dropbox , and Formspring in 2012 and possibly compromising personal details of over 100 million users, has pleaded not guilty in a U.S. federal court after being extradited from the Czech Republic. Yevgeniy Aleksandrovich Nikulin, 30, of Moscow was arrested in Prague on October 5, 2016, by Interpol agents working in collaboration with the FBI, but he was recently extradited to the United States from the Czech Republic on Thursday for his first appearance in federal court. Nikulin's arrest started an extradition battle between the United States and Russia, where he faces significantly lesser criminal charges of stealing $3,450 via Webmoney in 2009. But the Czech Republic ruled in favor of the United States. In the U.S., Nikulin is facing: 3 counts of computer intrusion 2 counts of intentional transmission of information, code, or command causing damage to a protected computer 2 counts of aggravated identity theft 1 count

The alleged Russian hacker, who was arrested by the Czech police in Prague last October on suspicion of massive 2012 data breach at LinkedIn, can be extradited to either the United States or Russia, a Czech court ruled on Tuesday. Yevgeniy Aleksandrovich Nikulin , a 29-years-old Russian national, is accused of allegedly hacking not just LinkedIn , but also the online cloud storage platform Dropbox , and now-defunct social-networking company Formspring. However, he has repeatedly denied all accusations. Nikulin was arrested in Prague on October 5 by the Czech police after Interpol issued an international arrest warrant against him. Nikulin appeared at a court hearing held inside a high-security prison in Prague on Tuesday and emaciated after eight months in solitary confinement. The court ruling, pending appeals, left the final decision in the hands of Czech Justice Minister Robert Pelikan, who can approve extradition to one of the countries and block the other. The United

Hacker puts up 167 Million LinkedIn Passwords for Sale

May 18, 2016Mohit Kumar
LinkedIn's 2012 data breach was much worse than anybody first thought. In 2012, LinkedIn suffered a massive data breach in which more than 6 Million users accounts login details, including encrypted passwords, were posted online by a Russian hacker. Now, it turns out that it was not just 6 Million users who got their login details stolen. Latest reports emerged that the 2012's LinkedIn data breach may have resulted in the online sale of sensitive account information, including emails and passwords, of about 117 Million LinkedIn users. Almost after 4 years, a hacker under the nickname "Peace" is offering for sale what he/she claims to be the database of 167 Million emails and hashed passwords, which included 117 Million already cracked passwords, belonging to LinkedIn users. The hacker, who is selling the stolen data on the illegal Dark Web marketplace " The Real Deal " for 5 Bitcoins (roughly $2,200), has spoken to Motherboard, confirming th

With a need to give more controls in users’ hands, LinkedIn has introduced a few new security features that the company says will help users of the social network for professionals keep their accounts and data more secure. SESSION ALERTS Just like Google, Facebook, Yahoo and other online services, LinkedIn has added a new option within the settings tab that allows users to see where and on what devices they are logged into their account. From there, users can sign out of various sessions with one click. This will include details about the users’ current sessions, the browser name, operating system, carrier and IP address, which is used to give an approximate location of the device through which the session is occurring. Just like the Facebook feature, LinkedIn lets people to approve the devices to be used, and if somebody accesses a user’s LinkedIn account from an unapproved device it will alert user.

A Free Chrome, Firefox and Safari web browser plugin floating around the web, called ' Sell Hack ' allows users to view the hidden email address of any LinkedIn user, means anyone can grab email addresses that we use for professional purposes. When installed, the ' Sell Hack ' plugin will pop up a ' Hack In ' button on LinkedIn profiles and further automatically mines email addresses of LinkedIn users. NOT A SECURITY BREACH It's not a Security breach, LinkedIn has confirmed that no LinkedIn data has been compromised, but rather this free extension rely on an algorithm that checks publicly available data in order to guess users’ email addresses. So without exploiting any loophole or vulnerability, Sell Hack is capable of predicting users' email addresses with OSINT (Open-Source Intelligence) techniques i.e. information collected from publicly available sources. It is also possible that, the Sell Hack extension is gathering data from

A few months back in September 2013 it was revealed that, Belgacom , the largest telecommunications company in Belgium was hacked and number of employees on Belgacom’s network, including their servers were compromised. Later in November 2013 , it was revealed that the NSA and GCHQ were behind the infiltration of the company’s computers, according to the document provided by the former NSA contractor Edward Snowden . The document detailed that the British intelligence agency GCHQ created fake ‘ LinkedIn ’ and ‘ Slashdot ’ pages to spy on computers of Belgacom network engineers.

Edward Snowden , a former contractor at America's National Security Agency (NSA) , has rocked the intelligence world by leaking secret documents which reveal the previously unknown extent of global spying. But looks like the NSA isn't the only one using dirty digital tricks to hack its targets. Back in September, it was reported that the UK's equivalent of the NSA, GCHQ had hacked Belgacom , a leading telecommunications provider in Belgium. Some New analysis of the Snowden papers by German magazine Der Spiegel shows that British intelligence agency GCHQ created fake LinkedIn and Slashdot pages to spy on computers of  Belgacom  network engineers. Communications networks are particularly valuable to spies, because they allow instant access to individual users. Belgacom provides internet access to dozens of key EU institutions based in its capital city Brussels and its global roaming exchange is a hub for connections between various international mobile network
