Did you know… last month's widespread WannaCry ransomware attack forced Microsoft to release security updates against EternalBlue SMB exploit for unsupported versions of Windows, but the company left other three Windows zero-day exploits unpatched? For those unaware, EternalBlue is a Windows SMB flaw that was leaked by the Shadow Brokers in April and then abused by the WannaCry ransomware to infect nearly 300,000 computers in more than 150 countries within just 72 hours on 12th of May. Shortly after WannaCry outbreak, we reported that three unpatched Windows exploits , codenamed " EsteemAudit, " " ExplodingCan ," and " EnglishmanDentist ," were also being exploited by individuals and state-sponsored hackers in the wild. Specially EsteemAudit , one of the dangerous Windows hacking tool that targets remote desktop protocol (RDP) service on Microsoft Windows Server 2003 and Windows XP machines, while ExplodingCan exploits bugs in IIS 6.0 and E...

In this year's annual event, Apple announced that the company had paid out $70 Billion to developers in the App Store's lifetime and that $21 Billion of the amount was paid in the last year alone. But has all this money gone to the legitimate app developers? Probably not, as app developer Johnny Lin last week analyzed the Apple's App Store and discovered that most of the trending apps on the app store are completely fake and are earning their makers hundreds of thousands of dollars through in-app purchases and subscriptions. Scammers Use 'Search Ads' Platform to Boost App Ranking Shady developers are abusing Apple's relatively new and immature App Store Search Ads, which was launched at last year's Worldwide Developers Conference (WWDC), to promote their app in the store by using a few strategically chosen search ads and a bit of SEO. "They're taking advantage of the fact that there's no filtering or approval process for ads, and ...

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...
