What is Ransomware?
Malware is any malicious software deliberately created to negatively affect a computer, machine, server, customer, or network. There are a wide array of malware types available, such as computer viruses, Trojan horses, worms, encryption malware, ransomware, adware, and fake security programs. Malware programmers use different techniques to develop malware, such as exploiting vulnerabilities in popular websites, creating infectious email attachments, stealing information through internet banking, and broadcasting unsolicited email to multiple people. Since malware writers are generally sophisticated computer hackers, some of the malware that spreads on the internet today was developed by inexperienced amateurs. Malware typically comes with a bundled with freeware or shareware program that comes with no guarantee and is usually advertised or recommended for sale.
Malware can be installed in a number of ways.
One of the most common methods is to install apps on a computer without the consumer’s knowledge. With the app installed, users browse various Internet sites that might contain malware such as pornography, drugs, and online casinos. When they try to surf elsewhere, they are redirected to dangerous websites that install additional malware onto the user’s computer. After a while, users may become victims of phishing scams, identity theft, and other malware that steal their bank accounts, confidential personal data, and accesses their computers via secured Wi-Fi connections.
The Android Market is one of the most popular mobile operating systems in the world today. Almost all smartphones and tablets run on this open source platform. Because of this, it is easy for malicious software to slip into an infected smartphone or tablet and install themselves on the device. Malware can also be distributed through other applications or media. For instance, many manufacturers copy their proprietary applications from other companies and distribute them free on their devices.
Malware and viruses spread when they are installed on a computer or network without the knowledge or consent of the user. They spread through various channels, including email attachments, p2p networks, files being shared on removable disks, and automatically through downloadable programs. In many cases, these channels are exploited through adware and spyware that install viruses into the devices of users. These channels are usually exploited through phishing scams. Phishing scams lure users to enter their personal and financial information into fake websites to trick them into buying or downloading harmful software.
Apart from adware and spyware, malware can also spread through various security vulnerabilities found in Android phones and tablets. One of these vulnerabilities includes the use of default applications that install network services, such as the Shared Storage Drivers and the USB driver. If the default or customized application installed uses a driver, such as the wrong USB driver, then it could leave behind a security vulnerability. Other vulnerabilities include insecure storage passwords and the insecure installation of ROMs.
Ransomware is also one of the most common forms of malware.
It works by locking the device’s memory and disrupting system performance. The name itself tells the entire story – ransomware creates its own encrypted file containing the ransom demand. The file needs to be converted into an executable file before it can be shared with the user, which could in turn allow attackers to access the contents and do damage to the operating system. The files normally encrypted with a private key, but this is only possible if the device’s SIM card or the PC’s hard drive is not stolen.
