Nothing comes for free, especially online. Would you be okay with allowing a few paid services to mine cryptocurrencies using your system instead of paying the subscription fee? Most free websites and services often rely on advertising revenue to survive, but now there is a new way to make money—using customers' computer to generate virtual currencies. It was found that a scheduling app, dubbed Calendar 2, was embracing cryptocurrency mining in exchange for free access to its app premium features, but the developer has to take it down from the Apple App Store following reports that it's not working as intended. Cryptocurrency mining is not a new concept, but the technology has recently exploded after hackers found it a great way to make millions of dollars by hijacking computers to secretly perform cryptocurrency mining in the background without users' knowledge or consent. Due to this cryptocurrency mining has emerged as one of the biggest threats in recent mon...

The team of security researchers—who last month demonstrated how attackers could steal data from air-gapped computers protected inside a Faraday cage—are back with its new research showing how two (or more) air-gapped PCs placed in the same room can covertly exchange data via ultrasonic waves. Air-gapped computers are believed to be the most secure setup wherein the systems remain isolated from the Internet and local networks, requiring physical access to access data via a USB flash drive or other removable media. Dubbed MOSQUITO , the new technique, discovered by a team of researchers at Israel's Ben Gurion University, works by reversing connected speakers (passive speakers, headphones, or earphones) into microphones by exploiting a specific audio chip feature. Two years ago, the same team of researchers demonstrated how attackers could covertly listen to private conversations in your room just by reversing your headphones (connected to the infected computer) into a micr...

Security researchers at Kaspersky have identified a sophisticated APT hacking group that has been operating since at least 2012 without being noticed due to their complex and clever hacking techniques. The hacking group used a piece of advanced malware—dubbed Slingshot —to infect hundreds of thousands of victims in the Middle East and Africa by hacking into their routers. According to a 25-page report published [ PDF ] by Kaspersky Labs, the group exploited unknown vulnerabilities in routers from a Latvian network hardware provider Mikrotik as its first-stage infection vector in order to covertly plant its spyware into victims' computers. Although it is unclear how the group managed to compromise the routers at the first place, Kaspersky pointed towards WikiLeaks Vault 7 CIA Leaks , which revealed the ChimayRed exploit , now available on GitHub , to compromise Mikrotik routers. Once the router is compromised, the attackers replace one of its DDL (dynamic link libraries) ...

Governments in Turkey and Syria have been caught hijacking local internet users' connections to secretly inject surveillance malware, while the same mass interception technology has been found secretly injecting browser-based cryptocurrency mining scripts into users' web traffic in Egypt. Governments, or agencies linked to it, and ISPs in the three countries are using Deep Packet Inspection technology from Sandvine (which merged with Procera Networks last year), to intercept and alter Internet users' web traffic. Deep packet inspection technology allows ISPs to prioritize, degrade, block, inject, and log various types of Internet traffic, in other words, they can analyze each packet in order to see what you are doing online. According to a new report by Citizen Lab, Turkey's Telecom network was using Sandvine PacketLogic devices to redirect hundreds of targeted users (journalists, lawyers, and human rights defenders) to malicious versions of legitimate progra...

Memcached reflections that recently fueled two most largest amplification DDoS attacks in the history have also helped other cybercriminals launch nearly 15,000 cyber attacks against 7,131 unique targets in last ten days, a new report revealed. Chinese Qihoo 360's Netlab, whose global DDoS monitoring service ' DDosMon ' initially spotted the Memcached-based DDoS attacks, has published a blog post detailing some new statistics about the victims and sources of these attacks. The list of famous online services and websites which were hit by massive DDoS attacks since 24th February includes Google, Amazon, QQ.com, 360.com, PlayStation, OVH Hosting, VirusTotal, Comodo, GitHub ( 1.35 Tbps attack ), Royal Bank, Minecraft and RockStar games, Avast, Kaspersky, PornHub, Epoch Times newspaper, and Pinterest. Overall, the victims are mainly based in the United States, China, Hong Kong, South Korea, Brazil, France, Germany, the United Kingdom, Canada, and the Netherlands. ...
