With each passing day, cyber security becomes progressively more important for everyday internet users, website owners and businesses. Despite the plethora of advances that are constantly being made on the security front, cybercriminals are continually stepping up their game. The spread of malicious software, commonly known as “malware,” has become increasingly prevalent over the last decade, and it shows no signs of letting up any time soon. As malware developers find increasingly clever ways to spread their wares, internet users must stay on their toes and remain vigilant. A single malware infection can have consequences that range from a hijacked computer to compromised financial information, so it’s imperative that people know what to watch for. In the quest to stay safe online, knowledge of the following forms of malware is sure to serve you well.
Bots
Software programs designed to fulfill specific functions automatically, bots are used for a variety of purposes – and not all of them are bad. For example, bots are commonly used in online games, contests and auctions. However, as any victim of a bot attack can confirm, they can also be utilized for criminal activity. This is particularly true in the case of botnets, which are series of computers that are under third party control. Botnets are commonly used to perpetrate DDoS attacks on websites and businesses. Additionally, individual bots can be used to spread malicious links, place malware-laden advertisements on websites and steal server data – among other things. In addition to CAPTCHA tests, website owners can stave off bots with the help of dependable security programs.

Fileless Malware
Although it’s among the least well-known varieties of malicious software, fileless malware accounts for nearly half of all malware attacks worldwide. This form of malware derives its name from its lack of reliance on files and file systems. Whereas traditional malware uses system files as a catalyst for spreading and infecting new targets, fileless malware spreads through memory, APIs, scheduled tasks and registry keys. More often than not, fileless malware exploits programs and operating system tools to in order to pass itself off as a sub-process. As a result, fileless malware can be considerably harder to detect and stamp out than traditional malicious software.
Viruses
Computer viruses may be on the decline, but they’re among the most dangerous forms of malicious software. Like real-life viruses, this breed of malware infects multiple files and programs and can rapidly spread to other devices and networks. After latching onto legitimate programs, viruses begin executing malicious code once these programs are opened. This can result in compromised host networks, the creation of botnets, stolen financial information and the propagation of unwanted ads. In the digital age, no internet-enabled device or website should be without a reliable virus-protection program.
Keyloggers
As the name suggests, a keylogger is a piece of malicious software that tracks and logs the infected party’s keystrokes. Keyloggers are often hard to detect and can result in stolen user names, financial information and other sensitive personal data. In most instances, keyloggers are spread through the use of malicious links and attachments found in emails, text messages and social media posts. Since this type of malware can elude security programs, make sure to watch for signs of keylogger infection. These include a device’s performance slowing down during web browsing, consistently delayed mouse clicks and keystrokes, and frequent error screens when web pages are loading. It should also be noted that keyloggers are sometimes used for non-malicious purposes, such as parental monitoring and police investigations.
Every day, countless internet users and websites find themselves besieged by malicious software. Unfortunately, once an infection occurs, it’s almost impossible to remedy the problem without experiencing some undesirable consequences. That being the case, it’s important to stay on your guard when engaged in any form of online activity. Whether you’re updating a website, posting on social media or even checking your email, malware may be lurking just around the corner. In the fight against malicious software, knowing your enemy is half the battle, and taking the time to familiarize yourself with some of malware’s most common varieties can prove helpful in preserving your online safety.
