The same group of hackers that caused the power outage across several regions in Ukraine last Christmas holidays might have once again shut down power supply in northern Ukraine during the weekend. According to Ukrainian energy provider Ukrenergo, a cyber attack on Kyiv's power grid may have caused the power outages in the country on Saturday, December 17, near midnight. The blackout affected the northern part of Kiev, the country's capital, and surrounding areas, Ukrenergo Director Vsevolod Kovalchuk explained in a post on Facebook. Shortly after the incident, Ukrenergo engineers switched to manual mode and started restoring power in approximately 30 minutes in an effort to deal with the cyber attack. Power was fully restored after just an hour and fifteen minutes of the blackout. According to Kovalchuk, the one responsible for the weekend outage could be an "external interference through data network," however, the company's cybersecurity experts a...

The biggest advertising fraud ever! A group of hackers is making between $3 Million to $5 Million per day from United States brands and media companies in the biggest digital ad fraud ever discovered. Online fraud-prevention firm White Ops uncovered this new Ad fraud campaign, dubbed " Methbot ," that automatically generates more than 300 Million fraudulent video ad impressions every day. The cyber criminal gang, dubbed AFT13, has developed Methbot robo-browser that spoofs all the necessary interactions needed to initiate, carry out and complete the ad transactions. The hackers, allegedly based in Russia, registered more than 6,000 domains and 250,267 distinct URLs impersonating brand and names of high-profile websites like ESPN, Vogue, CBS Sports, Fox News and the Huffington Post, and selling fake video ad slots. Cyber criminals behind Methbot are using servers hosted in Texas and Amsterdam to power more than 570,000 bots with forged IP addresses, mostly belong...

Next time when you hear an announcement in the flight, " Ladies and gentlemen, this is your captain speaking… ," the chances are that the announcement is coming from a hacker controlling your flight. Dangerous vulnerabilities in an in-flight entertainment system used by the leading airlines, including Emirates, United, American Airlines, Virgin, and Qatar, could let hackers hijack several flight systems and even take control of the plane. According to security researchers from IOActive , the security vulnerabilities resides in the Panasonic Avionics In-Flight Entertainment (IFE) system used in planes run by 13 major airlines, providing a gateway for hackers which is absolutely terrifying. The security holes could be exploited by hackers that could allow them to spoof flight information like map routes, speed statistics, and altitude values, and steal credit card information. IOActive's Ruben Santamarta managed to "hijack" in-flight displays to change info...

Ransomware has risen dramatically since last few years, so rapidly that it might have already hit you or someone you know. With hundred of thousands of ransomware variants emerging every day, it is quite difficult for traditional signature-based antivirus tools to keep their signature database up-to-date. So, if signature-based techniques are not enough to detect ransomware infection, then what else can we do? The solution is RansomFree . Boston-based cyber security firm Cybereason has released RansomFree — a real-time ransomware detection and response software that can spot most strains of Ransomware before it starts encrypting files and alert the user to take action. RansomFree is a free standalone product and is compatible with PCs running Windows 7, 8 and 10, as well as Windows Server 2010 R2 and 2008 R2. Instead of regularly updated malware signatures to fight the bad programs, RansomFree uses "behavioral and proprietary deception" techniques to detect ne...

Next time when you see an advertisement of your favorite pair of shoes on any website, even if it is legitimate, just DO NOT CLICK ON IT. …Because that advertising could infect you in such a way that not just your system, but every device connected to your network would get affected. A few days ago, we reported about a new exploit kit, dubbed Stegano , that hides malicious code in the pixels of banner advertisements rotating on several high profile news websites. Now, researchers have discovered that attackers are targeting online users with an exploit kit called DNSChanger that is being distributed via advertisements that hide malicious code in image data. Remember DNSChanger? Yes, the same malware that infected millions of computers across the world in 2012. DNSChanger works by changing DNS server entries in infected computers to point to malicious servers under the control of the attackers, rather than the DNS servers provided by any ISP or organization. So, wheneve...
