Threatware is a type of malicious software or malware that’s designed to damage a computer system’s files.
This includes any type of program that is designed to steal or destroy a victim’s personal data, including ransomware, spyware, worms, viruses, and keyloggers.
Hackers attempt to circulate threatware by tricking users into downloading an infected file. One of the most common ways hackers do this is with phishing and social engineering scams.
When using a phishing email to circulate malware, a hacker will send a user an email impersonating a friend, coworker, or trusted brand to mislead them into clicking on a malicious attachment or URL. Downloading the file or visiting the compromised website will infect the device with a malicious program.
Once the malicious program has made its way onto your computer, it can start to exfiltrate and export personal data from your device to send to the attacker.
It’s important to note that phishing is just one of many methods hackers can use to spread malicious software. Other methods include:
Devices infected by threatware or malware can start showing a number of signs of compromise. Some telltale effects of threatware include:
There are many different types of threatware that you should be aware of online. These include:
More and more examples of threatware are emerging on a daily basis. However, one of the most notorious examples is the trojan virus Emotet, which was first detected in 2014 when hackers targeted hundreds of customers of German and Austrian banks with spam emails.
Clicking on a link or attachment in these emails would infect the computer with Emotet, which would harvest sensitive data and then attempt to infiltrate surrounding computers on a network. This could cost up to $1 million per incident to remediate.
Another high-profile example of threatware emerged in 2017 with the Wannacry ransomware outbreak, which affected approximately 200,000 individuals and 10,000 organizations in over 150 countries.
In this instance, the WannaCry ransomware exploited an unpatched vulnerability in Windows XP to encrypt the user’s files and issued a pop-up noting that the files had been encrypted but could be unencrypted by making a payment to a linked Bitcoin address.
More recently, the threat of malicious software remains incredibly prominent online. In fact, according to SonicWall’s 2022 Cyber Threat Report, in 2022, there were 5.4 billion malware attacks and 623.3 million ransomware attacks.
This means users need to be proactive about staying safe online.
Prevention is the best defense against threatware. Avoiding downloading malicious files in the first place is much more effective than trying to contain an outbreak post-infection.
Here are some simple steps that users and organizations can take to avoid threatware infections:
If you believe your device has been infected, then removing the infection will depend on the type of threatware that your computer is experiencing.
That being said, there are some simple actions you can take to remove most forms of malware:
While threatware is incredibly prevalent online, if you follow basic cyber hygiene and some of the best practices outlined in this article, you can reduce your overall exposure to threat actors.
As a golden rule of thumb, if you’re unsure whether an email or website is legitimate or not, don’t click on it.
