They may feature links that direct the user towards convincing versions of their bank's website, compelling them to change their password and then sending the login information to a cybercriminal, or they may have infected attachments that immediately begin collecting data on their own once opened.
Web —Cybercriminals can design websites that exploit system vulnerabilities, human error and common sense. A typical example runs like this : A pop-up ad warns users that they have a virus, so they need to click OK to clean their system registry and get rid of the virus. In fact, clicking OK is what installs the virus on the host system. Other variants include browser exploitation or DNS redirects.
Direct —Direct vectors include using a USB infected device, exploiting the host operating system from within the network or social engineering tactics. Social engineering is one of the most popular methods of gaining access to closed systems: the idea is to trick a user into compromising their own security. For instance, an attacker may scan a public LinkedIn profile to find an employee's name and title, get their phone number from the company website and then call them, pretending to be from the IT department and asking for login credentials.
As simple as it sounds, it works surprisingly well. How to Safeguard Your Business From Malware Attacks With cyber threats on the rise, and ransomware occurrences becoming increasingly common, there is no better time than now to implement a robust cybersecurity defense against malware.
The best way to do this is by : Adopting a secure corporate culture —Instruct employees to be suspicious. When someone receives an unexpected email that appears to come from the CEO or CFO, they need to feel entitled to pick up the phone and call that individual to confirm.
Your directors and executives may get annoyed by dealing with the extra work, but it's nothing compared to losing a few million dollars because a hacker impersonated one of them and gained access to the company bank account. Keeping comprehensive, easily recoverable backups —Since there is often no way to decrypt files compromised by ransomware, your only course of action is continuing business from a backup.
If you have a comprehensive, highly organized data recovery strategy, this can take as little as ten minutes' time and cost nothing. If your backup strategy is inefficient, irregular or unorganized, however, migrating all your data can take days or even weeks. Restricting trusted access points —Find out what points of access in your data infrastructure are unrestricted or automatically trusted and ask why they are so.
While it may be convenient, these trusted communications channels offer clear paths for malware applications to propagate through. Entering a few more passwords or implementing a two-step authentication for business-critical processes can save you in the long run. These can seek to spy on your activities or steal confidential personal information. As one recent example, a Netflix scam saw people infected with the SpyNote RAT posing as a genuine Netflix app and subsequently spying on user activity.
Meanwhile, more recently, the Pegasus iOS spyware allowed adversaries to silently jailbreak Apple devices, spy on victims and collect voice, camera, email, messaging, GPS and contact data. These infected apps often look to steal contact and personal information, SMS messages, track devices and phone calls, capture keyboard outputs or perform DoS attacks.
They could also force your device into botnet. Some of the most common ways your computer can become infected with spyware include these:. Spyware can be difficult to recognize on your device. You may have a spyware issue if your computer shows these symptoms.
If you think your device is infected with spyware, run a scan with your current security software to make sure it has cleaned up everything it can. Next, download and run a virus removal tool, such as the free Norton Power Eraser. There are also other reputable anti-spyware removal tools. Some of them work only when you manually start the scan.
Spyware can be harmful, but it can be removed and prevented by being cautious and using an antivirus tool. Be proactive by changing your passwords and notifying your bank to watch for fraudulent activity.

Once inside the city, the soldiers jumped out of the horse and stormed the walls from the inside, opening the gates and letting their comrades in to take over the city.
Similar to this story, a Trojan is an innocent-looking program that, when downloaded, opens a virtual "back door" in your device's security , allowing malware to come in and infect it. Like viruses, Trojans require human interaction to spread. Trojans are also known to wreak havoc on your computer by causing pop-up windows, deleting files, stealing data, etc. Adware uses information it has collected on you, such as your Internet browsing history, to serve you targeted advertisements.
Though adware is relatively harmless, it can be a nuisance because it can slow down your computer or cause a lot of pop-ups ads. However, by breaking through your security to gather information on you, adware can potentially create a security gap that allows other more harmful versions of malware into your network.
If you want to invest in a solid foundational malware solution, consider downloading anti-malware and content filtering software. Anti-malware software is designed to recognize and remove malware threats from your network. One way that anti-malware software recognizes threats is by searching for snippets of code that it deems suspicious. When this code is recognized, the software flags it.
Another way that anti-malware software detects threats is by recognizing code that attempts abnormal behavior. For instance, a snippet of code that attempts to gain administrator rights to your computer without asking for your permission could be flagged. Different versions of anti-malware software exist for home or business use. Depending on what you need it for, you can tailor anti-malware to fit your needs. Content and web filtering software can also assist in blocking malware threats.
This software can be tailored to restrict Internet access so users cannot use inappropriate websites that may contain malware, such as illegal movie streaming sites. Educating employees about cyber security starting from when they're hired helps to build a company culture around the importance of cyber security.
You could have a process as simple as an educational pamphlet that the new hire has to read and take a test about during the first week of their employment. Creating a monthly company cyber security newsletter can serve as an informative and engaging way to constantly educate your employees about the latest cyber security threats as well as serve as a way to share tips on staying safe online.
Another engaging way to see how educated your employees are about cyber security is to utilize penetration testing. Penetration testing is a fake phishing attack that aims to see which employees fall for the attack by clicking on fake links or downloading fake files. If employees fall for these phishing attempts then you can send them through cyber security training, again. We recommend conducting these tests quarterly. To better secure your network, we recommend conducting a thorough audit of your network infrastructure quarterly to identify security gaps and build a roadmap to better network security.
