Ransomware has been around for a few years, but it has become an albatross around everyone's neck, targeting businesses, hospitals, financial institutions and individuals worldwide and extorting millions of dollars. Forget about developing sophisticated banking trojans and malware to steal money out of people and organizations. Today, one of the easiest ways that can help cyber criminals get paid effortlessly is Ransomware. This threat became even worse after the arrival of ransomware as a service (RaaS) – a variant of ransomware designed to be so user-friendly that anyone with little or no technical knowledge can also easily deploy them to make money. Now, security researchers have uncovered an easy-to-use ransomware service that promises profit with just one successful infection. Dubbed Karmen , the RaaS variant is based on the abandoned open-source ransomware building toolkit dubbed Hidden Tear and is being sold on Dark Web forums from Russian-speaking hacker named D

You should be very careful while visiting websites on the Internet because you could be hit by a new upgrade to the World's worst Exploit Kit – Angler , which lets hackers develop and conduct their own drive-by attacks on visitors' computers with relative ease. Many poorly-secured websites are targeting Windows users with a new "Cocktail" of malware that steals users' passwords before locking them out from their machines for ransom. Yes, stealing Windows users' passwords before encrypting their data and locking their PCs for ransom makes this upgrade to the Angler Exploit Kit nastier. Here's How the New Threat Works: Once the Angler exploit kit finds a vulnerable application, such as Adobe Flash, in visitor's computer, the kit delivers its malicious payloads, according to a blog post published by Heimdal Security. The First Payload infects the victim's PC with a widely used data thief exploit known as Pony that systematic

October 01, 2015Swati Khandelwal
Apple Mac Computers are considered to be invulnerable to malware, but the new Exploit discovered by security researchers proves it indeed quite false. Patrick Wardle , director of research at security firm Synack , has found a deadly simple way that completely bypass one of the core security features in Mac OS X i.e.  Gatekeeper . Introduced in July of 2012, Gatekeeper is Apple's anti-malware feature designed to keep untrusted and malicious applications from wreaking havoc on Macs. However, Wardle has found a quick and simple way to trick Gatekeeper into letting malicious apps through on Mac OS X machines, even if the protection is set to open apps downloaded only from the Mac App Store. According to the researcher, before allowing any apps to execute on an OS X machine, Gatekeeper performs a number of checks, such as: Checking the initial digital certificate of a downloaded app Ensuring the app has been signed with an Apple-recognized developer certificat

A newly discovered zombie network that exclusively targets Apple computers running Mac OS X across the globe has compromised roughly 17,000 machines so far, giving hackers backdoor access to infected computers, researchers at Russian antivirus firm Dr.Web warned. According to a survey of traffic conducted in September by researchers at Dr. Web, over 17,000 Macs globally are part of the Mac.BackDoor.iWorm botnet , which creates a backdoor on machines running OS X. Researchers say almost a quarter of iWorm botnet are located in the US. The most interesting thing to notice about this botnet is that it uses a special method of spreading via a search service of Reddit posts to a Minecraft server list subreddit to collect the IP addresses for its command and control (CnC) network. The user who had posted that subreddit data has now been shut down though the malware creators are likely to form another server list. " It is worth mentioning that in order to acquire a control server add
