Over 800 different Android apps that have been downloaded millions of times from Google Play Store found to be infected with malicious ad library that silently collects sensitive user data and can perform dangerous operations. Dubbed " Xavier ," the malicious ad library, initially emerged in September 2016, is a member of AdDown malware family, potentially posing a severe threat to millions of Android users. Since 90 percent of Android apps are free for anyone to download, advertising on them is a key revenue source for their developers. For this, they integrate Android SDK Ads Library in their apps, which usually doesn't affect an app's core functionality. According to security researchers at Trend Micro , the malicious ad library comes pre-installed on a wide range of Android applications, including photo editors, wallpapers and ringtone changers, Phone tracking, Volume Booster, Ram Optimizer and music-video player. Features of Xavier Info-Stealing Malware...

Last December, a cyber attack on Ukrainian Electric power grid caused the power outage in the northern part of Kiev — the country's capital — and surrounding areas, causing a blackout for tens of thousands of citizens for an hour and fifteen minutes around midnight. Now, security researchers have discovered the culprit behind those cyber attacks on the Ukrainian industrial control systems. Slovakia-based security software maker ESET and US critical infrastructure security firm Dragos Inc. say they have discovered a new dangerous piece of malware in the wild that targets critical industrial control systems and is capable of causing blackouts. Dubbed " Industroyer " or " CrashOverRide ," the grid-sabotaging malware was likely to be used in the December 2016 cyber attack against Ukrainian electric utility Ukrenergo , which the security firms say represents a dangerous advancement in critical infrastructure hacking. According to the researchers, CrashO...

WannaCry , the biggest ransomware attack in the history, gained prominence very rapidly in the media globally after the ransomware infected more than 300,000 computers in over 150 countries within just 72 hours. Governments, Intelligence agencies and law enforcement around the world have already started their investigations and are working closely with affected companies to track down hackers responsible for the global cyber attack launched on Friday, 12th May. Some researchers traced back WannaCry to a state-sponsored hacking group in North Korea, while other believed the perpetrators might be Chinese . If you have been following WannaCry coverage on The Hacker News, you should be aware of that the WannaCry ransomware uses Tor hidden service to communicate with its command-and-control server. Just yesterday, we came to know that French authorities had seized at least 6 Tor's entry guard node servers, hosted on France-based hosting providers, just two days after the o...

Remember SambaCry ? Two weeks ago we reported about a 7-year-old critical remote code execution vulnerability in Samba networking software (re-implementation of SMB networking protocol) that allows a remote hacker to take full control of a vulnerable Linux and Unix machines. To know more about the SambaCry vulnerability (CVE-2017-7494) and how it works, you can read our previous article . At that time, nearly 485,000 Samba-enabled computers were found to be exposed on the Internet, and researchers predicted that the SambaCry-based attacks also have potential to spread just like WannaCry ransomware widely. The prediction came out to be quite accurate, as honeypots set up by the team of researchers from Kaspersky Lab have captured a malware campaign that is exploiting SambaCry vulnerability to infect Linux computers with cryptocurrency mining software. Another security researcher, Omri Ben Bassat‏, independently discovered  the same campaign and named it "EternalMiner...

Social media networks are no doubt a quick and powerful way to share information and ideas, but not everything shared on Facebook or Twitter is true. Misinformation, or "Fake News," has emerged as a primary issue for social media platforms, seeking to influence millions of people with wrong propaganda and falsehoods. In past years, we have seen how political parties and other groups have used spoofed social media profiles of influencers or leaders to spread misinformation, and most of the time such techniques work to successfully convince people into believing that the information is true. Although social media services like Facebook, Twitter, and Google, offers account verification (verified accounts with blue tick) for public figures, we have seen hackers hijacking verified accounts to spread fake news from legitimate account to their millions of followers. Now, researchers have uncovered a new, cunning attack technique currently being used by hackers to take ove...
