According to the Identity Theft Resources Center, there were 2,365 cyberattacks last year, with more than 343 million victims. As the world becomes more interconnected and reliant on digital technology, cybercrime will persist.
Ransomware is one of the most prevalent types. This refers to malware that encrypts computer files. Then, attackers demand a ransom in exchange for decryption keys.
How can ransomware be delivered? This is one of the most important questions when assessing threats.
Below are the top four ransomware cyberattack methods. Please keep reading to learn more, along with some ways to prevent it.
1. Email Phishing
The majority of ransomware is delivered through email. Phishing tactics involve attackers sending out emails that appear legitimate. These trick the users into clicking on a malicious link or attachment, which triggers the malware.
Identifying these data security threats is the best way to prevent them. For instance, hovering over URLs (before clicking) prompts your browser to display a preview of the site.
Examining the sender’s email is another easy yet effective way to combat ransomware. If it looks suspicious and is from someone you do not know, err on the side of caution and do not open any links or attachments.
2. Malvertising
Another common way that ransomware gets delivered is through malicious advertisements. These link to sites that initiate the download of ransomware programs.
Not clicking on random advertisements is an easy way to avoid this issue. However, some sites make it difficult to determine exactly what you are clicking on. For this reason, many businesses look at safety nets.
Using secure browsers, which have built-in security features, is one. You can invest in programs that have ad-blockers that can filter out malicious advertisements. Finally, keeping operating systems updated is another way to minimize network vulnerabilities.
3. Removable Media
Another way that ransomware can make its way onto devices is through removable media, like USB drives. The way this usually happens is the drive is used on an exposed device and is loaded with ransomware. When it transfers to another device, the ransomware program is automatically deployed.
This type of attack is particularly insidious because the physical transfer gets around firewalls and other network protections. The good news is that there are simple ways to avoid this.
One is to be cautious about using unknown devices and disable “auto-run” features for removable media. You can also use programs that scan media and hardware for threats.
4. Exploit Kits
Exploit kits are tools used by cybercriminals to scan vulnerable systems. They look for software with exposures, such as operating systems, plugins, networks, and browsers. Once a vulnerability is identified, the programs deliver the ransomware.
The best way to protect against exploits is to do regular updates on your operating system and applications. You can also use antivirus solutions, which specialize in shoring up frailties in systems and combatting any attacks that do occur.
