Ransomware has been around for a few years, but in last two years, it has become one of the fastest growing threats to businesses and users across the world, so will be in 2017. Ransomware is a piece of malware that encrypts files on your computer with strong encryption algorithms and then demands a ransom money in Bitcoin to decrypt the data so you can regain access to your encrypted files. We have seen some nastier ransomware infections over the past couple of years. The most interesting one was Popcorn Time that decrypts victims files for free if they pass the infection on to other people. Now, a new strain of ransomware takes the infection to a whole new level of craziness. Dubbed Koolova , the ransomware will restore your encrypted files for free, just like Popcorn Time. The only difference between both the infections is that you don't have to infect others to get free decryption key. Instead, all you have to do is educate yourself about ransomware by reading two...

What a good start of the New Year for those holding Bitcoins! Web-based digital currency Bitcoin has passed $1,110 for the first time on the Bitstamp Price Index (BPI) since early November 2013. Bitcoin broke the barrier on 1 January and now is trading above $1,150 mark at the time of writing, marking a bright beginning to 2017 for the digital currency. At the time of writing, 1 Bitcoin = $1158.99. Bitcoin is a revolutionary virtual currency that has no central authority; instead, it relies on thousands of computers worldwide that validate transactions and add new Bitcoins to the system. The world's first and most famous cryptocurrency is developed around Blockchain, which is a complex cryptographic protocol and a global computer's network that oversees and verifies which Bitcoins have been spent by whom. The identity of the people spending Bitcoins is extremely difficult to trace because of its anonymous nature. Therefore, the currency is very popular among criminal...

The U.S. Federal Trade Commission has announced a "prize competition" for creating a software or hardware-based solution with the ability to auto-patch vulnerable Internet of Things (IoT) devices. Today we are surrounded by a number of Internet-connected devices. Our homes are filled with tiny computers embedded in everything from security cameras, TVs and refrigerators to thermostat and door locks. While IoT is going to improve life for many, the number of security risks due to lack of stringent security measures and encryption mechanisms in the devices have increased exponentially, giving attackers a large number of entry points to affect you in some or the other way. Remember Mirai Botnet ? A botnet of just 100,000 hijacked IoT devices was used to flood the Dyn DNS service with unwanted requests and close down the Internet for Millions of Users a few months ago. At that time, Chinese firm Hangzhou Xiongmai Technology admitted its smart products – DVRs and ...

Nearly two years back, we warned users about publicly accessible MongoDB instances – almost 600 Terabytes (TB) – over the Internet which require no authentication, potentially leaving websites and servers at risk of hacking. These MongoDB instances weren't exposed due to any flaw in its software, but due to a misconfiguration (bad security practice) that let any remote attacker access MongoDB databases without using any special hacking tool. MongoDB later resolved the issue in the next version of its software by setting unrestricted remote access by default in the configuration, thousands of site administrators have not updated their servers yet. But trust me, they'll now regret this! A Hacker is now hijacking and wiping out unsecured MongoDB databases , but keeping a copy of those databases for asking administrators a ransom of 0.2 Bitcoins (nearly US$211) to return the lost data. So, admins without backups are left in a bind. In fact, the rising price of Bitcoin...

A security researcher recently reported a critical vulnerability in one of the most popular open source PHP libraries used to send emails that allowed a remote attacker to execute arbitrary code in the context of the web server and compromise a web application. Disclosed by Polish security researcher Dawid Golunski of Legal Hackers, the issue ( CVE-2016-10033 ) in PHPMailer used by more than 9 Million users worldwide was thought to be fixed with the release of version 5.2.18. However, Golunski managed to bypass the patched version of PHPMailer that was given a new CVE ( CVE-2016-10045 ), which once again put millions of websites and popular open source web apps, including WordPress, Drupal, 1CRM, SugarCRM, Yii, and Joomla, at risk of remote code execution attack. PHPMailer eventually fixed the issue with an update, version 5.2.20 . All versions of PHPMailer before this critical release are affected, so web administrators and developers are strongly recommended to update to t...
