Spyware Threat

[Nerio Cintron]

Spywareis loosely defined as malicious software designed to enter your computer device, gather data about you, and forward it to a third-party without your consent. Spyware can also refer to legitimate software that monitors your data for commercial purposes like advertising. However, malicious spyware is explicitly used to profit from stolen data.

More commonly, you will face the damage spyware can do to your computer. Spyware can be poorly designed, leading to system-draining performance. The lack of performance optimization can take up an enormous amount of your computer's memory, processing power, and internet bandwidth. As a result, infected devices may run slowly and lag in between applications or while online. Worse cases include frequent system crashing or overheating your computer, causing permanent damage. Some spyware can even disable your internet security programs.

Spyware can also manipulate search engine results and deliver unwanted websites in your browser, which can lead to potentially harmful websites or fraudulent ones. It can also cause your home page to change and can even alter some of your computer's settings. Pop-up advertisements are an equally frustrating issue that accompanies some types of spyware. Advertisements may appear even when offline, leading to inescapable annoyances.

The best way to control spyware is by preventing it from getting on your computer in the first place. However, avoiding program downloads and email attachments isn't always an option. Sometimes, even a trusted website can become compromised and infect your computer.

As your first line of defense, seek out internet security solutions with reliable antivirus and antimalware detection capabilities. Check that they have proactive protection as well. If your computer is already infected, many security providers offer spyware removal utilities to assist in identifying and removing spyware. Be sure to use a reliable internet security provider when choosing a Spyware removal tool. Certain utilities can be fraudulent and be spyware themselves.

There are several free antivirus solutions available. While a free antivirus trial is an excellent way to figure out which product is best for you, don't rely on a solution that promises unlimited protection at no cost. They will often lack certain features that are valuable for avoiding spyware schemes. Tools like a virtual encrypted keyboard for entering financial information, or a strong anti-spam filter and cloud-based detection system help to eliminate risks.

Spyware, and its associated malicious programs like malware and viruses, will always be a danger as long as you use an Internet-connected device. Protecting your finances and identity needs to be a top priority, and it simply can't be done through understanding the problem alone. Get yourself some Internet Security to help you protect your devices from potential spyware attacks.

Kaspersky Internet Security received two AV-TEST awards for the best performance & protection for an internet security product in 2021. In all tests Kaspersky Internet Security showed outstanding performance and protection against cyberthreats.

Spyware is a type of malicious software -- or malware -- that is installed on a computing device without the end user's knowledge. It invades the device, steals sensitive information and internet usage data, and relays it to advertisers, data firms or external users.

Any software can be classified as spyware if it is downloaded without the user's authorization. Spyware is controversial because, even when it is installed for relatively innocuous reasons, it can violate the end user's privacy and has the potential to be abused.

Spyware is one of the most common threats to internet users. Once installed, it monitors internet activity, tracks login credentials and spies on sensitive information. The primary goal of spyware is usually to obtain credit card numbers, banking information and passwords.

But spyware can also be used to track a person's location, as is the case with stalkerware. Often installed secretly on mobile phones by jealous spouses, ex-partners and even concerned parents, this type of spyware can track the physical location of the victim, intercept their emails and texts, eavesdrop on their phone calls and record conversations, and access personal data, such as photos and videos.

Spyware can be difficult to detect; often, the first indication a user has that a computing device has been infected with spyware is a noticeable reduction in processor or network connection speeds and -- in the case of mobile devices -- data usage and battery life. Antispyware tools can be used to prevent or remove spyware. They can either provide real-time protection by scanning network data and blocking malicious data, or they can execute scans to detect and remove spyware already on a system.

Spyware can make its way onto a device without the end user's knowledge via an app install package, file attachment or malicious website. In its least damaging form, spyware exists as an application that starts up as soon as the device is turned on and continues to run in the background. Its presence will steal random access memory and processor power and could generate infinite pop-up ads, effectively slowing down the web browser until it becomes unusable.

Spyware may also reset the browser's homepage to open to an ad every time or redirect web searches and control the provided results, making the search engine useless. Additionally, spyware can change the computer's dynamic link libraries, which are used to connect to the internet, resulting in connectivity failures that can be hard to diagnose.

At its most damaging, spyware will track web browsing history, passwords and other private information, such as email addresses, credit card numbers, personal identification numbers or banking records. All of this information can be gathered and used for identity theft or sold to third parties. Information can be collected using keyloggers and screen captures.

Spyware can also secretly make changes to a device's firewall settings, reconfiguring the security settings to allow in even more malware. Some forms of spyware can even identify when the device is trying to remove it from the Windows registry and will intercept all attempts to do so.

Spyware is most commonly distributed by getting potential victims to click on a link. The link can be in an email, pop-up window or ad. Malicious code can also be embedded on legitimate websites as an advertisement. Other ways for spyware to infect a machine include via drive-by download -- where spyware is downloaded just by visiting a website or viewing a HyperText Markup Language email message -- phishing links or physical devices.

Adware. Malicious adware is often bundled with free software, shareware programs and utilities downloaded from the internet or surreptitiously installed onto a user's device when the user visits an infected website. Many internet users were first introduced to spyware in 1999 when a popular freeware game called Elf Bowling came bundled with tracking software. Adware is often flagged by antimalware programs as to whether the program in question is malicious or not.

Cookies that track and record users' personally identifiable information (PII) and internet browsing habits are one of the most common types of adware. An advertiser might use tracking cookies to track what webpages a user visits in order to target advertising in a contextual marketing campaign. For example, an advertiser could track a user's browser history and downloads with the intent to display pop-up or banner advertisements to lure the user into making a purchase. Because data collected by spyware is often sold to third parties, regulations such as the General Data Protection Regulation have been enacted to protect the PII of website visitors.

Keyboard loggers. Keyloggers are a type of system monitor that cybercriminals often use to steal PII, login credentials and sensitive enterprise data. Employers may also use keyloggers to observe employees' computer activities; parents to supervise their children's internet usage; device owners to track possible unauthorized activity on their devices; or law enforcement agencies to analyze incidents involving computer use.

Hardware keyloggers resemble a Universal Serial Bus flash drive and serve as a physical connector between the computer keyboard and the computer, while software keylogging programs do not require physical access to the user's computer for installation. Software keyloggers can be downloaded on purpose by someone who wants to monitor activity on a particular computer, or they can be downloaded unwittingly and executed as part of a rootkit or remote access Trojan.

Trojans. Trojans are typically malware programs that are disguised as legitimate software. A victim of a Trojan could unknowingly install a file posing as an official program, enabling the Trojan to access the computer. The Trojan can then delete files, encrypt files for ransom or enable other malicious actors to have access to the user's information.

Mobile spyware. Mobile spyware is dangerous because it can be transferred through Short Message Service or Multimedia Messaging Service text messages and typically does not require user interaction to execute commands. When a smartphone or tablet gets infected with mobile spyware that is sideloaded with a third-party app, the phone's camera and microphone can be used to spy on nearby activity, record phone calls, and log browsing activity and keystrokes. The device owner's location can also be monitored through the Global Positioning System (GPS) or the mobile computing device's Accelerometer.

To further reduce the probability of infection, network administrators should practice the principle of least privilege and require remote workers to access network resources over a virtual private network that runs a security scan before granting access privileges.
