Spyware is a type of malware that tries to keep itself hidden while it secretly records information and tracks your online activities on your computers or mobile devices. It can monitor and copy everything you enter, upload, download, and store. Some strains of spyware are also capable of activating cameras and microphones to watch and listen to you undetected.
By definition, spyware is designed to be invisible, which can be one of its most harmful attributes — the longer it goes undetected, the more damage it can cause. It’s like a virtual stalker that follows you through your device usage, collecting your personal data along the way. Strictly speaking, there are some valid applications of spyware. For example, your employer might have a security policy that allows them to use software to monitor usage of employee computers and mobile devices. The aim of company spyware is generally either to protect proprietary information or to monitor employee productivity. Parental controls that limit device usage and block adult content are also a form of spyware. Chances are you’ll be aware of any benign spyware when it’s on a device you’re using. For the purposes of this article, we’ll focus on malicious spyware; that is, spyware that sneaks its way onto your device without your knowledge, and with ill intent. Is spyware a virus?Spyware and viruses are both common examples of malicious software (malware), but otherwise, they’re not closely related. The difference between the two lies in their behavior: a computer virus inserts itself into a host program to copy itself and spread through networks of devices; spyware is designed to sit undetected on each device it infects. Some types of viruses can bring spyware along for the ride as they spread. But that’s not the only way to contract a nasty spyware infection: you can also pick up all kinds of malware from unsafe websites, suspicious links and email attachments, and infected hardware like USB drives. What does spyware do, exactly?Spyware can be used to track and record activity on computers and mobile devices. Specific strains have specific behaviors; generally speaking, cyberthieves use spyware to collect data and personal information. Once it’s on your computer or mobile device, spyware can carry out a distressing array of covert operations, including:
Unfortunately, these capabilities have attracted the interest of stalkers and jealous partners; in some circles, spyware is referred to as stalkerware or spouseware. The National Network to End Domestic Violence worked together with Avast to compile some tips to combat spyware and other invasive smart device applications for those struggling in abusive situations and relationships. Certain spyware providers market their products as parental control or employee monitoring programs and claim they’re doing their best to discourage consumers from using their products to spy on people. But their advertising tactics and disclaimers are akin to those for massage wands — sure, one can use the product according to the manufacturer’s instructions, but one is more likely using it to achieve goals the manufacturer can’t mention in its marketing materials. Types of spywareSpyware has uses beyond secretly monitoring and storing its targets’ online activities and capturing sensitive data. Some strains can force unwanted pop-up ads into your internet browsing experience or surreptitiously overtax the processor in your computer or mobile device. Others are used to create traffic for websites. Here’s a roundup of some of the most common varieties of spyware out there.
Who is most under threat?Criminals use spyware to stealthily collect sensitive information from individuals and businesses. People who rely heavily on online banking are particularly alluring targets for hackers looking to capture financial details to either use themselves or sell to other criminals. Businesses need to be especially vigilant against spyware to protect their finances and, perhaps more importantly, to keep a highly effective corporate espionage tool out of their networks. There are also high-profile cases of authoritarian governments using spyware to secretly keep tabs on journalists and human rights activists. Furthermore, some companies based in countries like China or Russia, such as Moscow-based Kaspersky, have been labeled a security risk by Western governments due to possible state interference and misuse of their software. As with most malware, we’re all one careless click, tap, download, or installation away from falling victim to spyware. Some sophisticated strains of spyware can even infect mobile devices through calling apps such as Skype. One highly advanced variant exploits a vulnerability in WhatsApp that enables it to infect smartphones regardless of whether or not targets answer attacker calls. Generally speaking, everyone who uses a computer, smartphone, tablet, or smart device or appliance can become a target of malware. While Windows users are most at risk, spyware has evolved to the point where a growing number of strains are capable of infecting Macs, as well as iOS and Android devices. Spyware and mobile devicesIf we take the thriving mobile spyware industry as an indicator, this form of malware is on the rise. The notorious mobile spyware strain called Pegasus has been repeatedly used against politcians, journalists, and activists around the world. And while the developers of “mobile monitoring software” claim their products are for employers and parents, there’s nothing stopping anyone from using them for nefarious purposes. the developers of “mobile monitoring software” claim their products are for employers and parents, there’s nothing stopping anyone from using them for nefarious purposes. It’s important to understand that smartphones and tablets, like computers, are vulnerable to a wide array of malware. A consistent increase in usage offers cybercriminals a growing quantity of targets. At the same time, increasingly complex hardware and networks are facilitating the development of new, more powerful malware. On top of this, smartphones offer attackers an additional means of infiltration: text messaging, or SMS. You can prevent many mobile threats with a mobile antivirus.
