Keyloggers: This is a sophisticated form of spyware in which your keystrokes are recorded, meaning that information is liable to be shared outside of your organization. Keylogging can also be legal, for example if an IT department needs to help you. However, in terms of spyware, it is often used for criminal activity.
This can lead to sensitive information being leaked. Spyware can have enormous effects on a business. For example, spyware can steal sensitive information such as personal data and intellectual property, things which people and businesses are particularly sensitive about keeping secure. In a more extreme form, spyware can even commit identity theft by logging keystrokes so that credit card numbers and passwords can be communicated to the hacker.
Furthermore, spyware is able to track any digital movements and redirect URLs to malicious websites — all of which can be a real hassle in daily work life. Spyware can cause even more chaos by shutting down computer systems meaning that certain vital information is in danger of being destroyed, such as financial records. Spyware removal can be difficult, so upfront prevention is worthwhile.
Companies should also put a major focus on educating employees and introducing clear guidelines. 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. Spyware also affects network and device performance, slowing down daily user activities. By becoming aware of how spyware works, you can avoid issues in enterprise and personal use.

As such, the spyware definition is reserved mostly for malicious applications nowadays. Malicious spyware is a type of malware specifically installed without your informed consent. Step-by-step, spyware will take the following actions on your computer or mobile device:. In short, spyware communicates personal, confidential information about you to an attacker.
The information gathered might be reported about your online browsing habits or purchases, but spyware code can also be modified to record more specific activities. Data compromised by spyware often includes collecting confidential info such as:. The methods by which spyware gets onto your computer and mobile devices can vary. Malicious spyware needs to mask itself carefully to install and operate unnoticed.
This malware may be in or alongside legitimate programs and websites via vulnerability exploits, or in custom-designed fraudulent apps and sites. Bundleware, or bundled software packages, are a common delivery method for spyware. In this case, the software attaches itself to some other program you intentionally download and install. Some bundled spyware installs discreetly without warning. Other times, your desired software will describe and require the spyware in the license agreement — without using that term.
By forcing you to agree to the full software bundle to install the desired program, you are voluntarily and unknowingly infecting yourself. Alternatively, spyware can get into a computer through all the avenues that other malware takes, such as when the user visits a compromised website or opens a malicious attachment in an email.
Note: Be aware that spyware is different from viruses. While both are types of malware that hide within your device, viruses are designed to replicate and embed into your other device files.
Spyware does not have this replication trait. The lesser of these harmful types will simply monitor and send your data off to the attacker — like tracking cookies. System monitors and adware are far worse, as they can gather data and may also make modifications to your system that expose you to other threats. In explaining why spyware is bad, we must unpack the explicit problems you can face when exposed to spyware. Threats can range from mild inconveniences to long-term financial damage.
Among these problems, below are some of the most common:. First, and perhaps most importantly, spyware can steal personal information that can be used for identity theft. If malicious software has access to every piece of information on your computer, it can harvest more than enough information to imitate your identity. Information used for this purpose includes browsing history, email accounts, and saved passwords for online banking, shopping, and social networks.
Also, if you've visited online banking sites, spyware can siphon your bank account information or credit card accounts and sell it to third parties — or use them directly. 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.
Another response to the threat of spyware is for computer users to change their online behavior to minimize their risk of encountering spyware. This can include not opening email attachments, not visiting particular websites, not downloading music or video files, or changing web browsers.
A recent study indicates that computer users who have been victimized by spyware are more likely to make these types of behavioral changes than are individuals who have not been victimized. State and federal legislators have addressed the problem of spyware.
In , anti-spyware legislation was introduced at the federal level and in 28 states. Such legislation typically seeks to establish criminal penalties for unauthorized dissemination and use of spyware programs.
Summary While Internet users can reduce the possibility of being victimized by spyware, cyberthieves have substantial financial incentives to continue to develop newer and more sophisticated spyware programs.
