ESET specialists have prepared a list of the most common online threats and effective computer security tips.
Since the beginning of the full-scale Russian invasion, Ukrainians have increasingly become the targets of cybercriminals. Recently discovered threats include malware from the group Armageddonwhich is downloaded by opening attachments in emails purporting to be from the National Academy of the SBU.
In addition, new online fraud schemes regularly appear on the Internet, in particular, the attackers distributed messages on the topic of “help from the Red Cross” with phishing links in popular instant messengers. To steal data for entering online banking, scammers disguised themselves as representatives of Ukrainian banks.
Given the constant cyber attacks and scams targeting Ukrainian users, ESET specialists have prepared a list of the most common online threats and effective computer security tips.
1. Phishing attacks
As a rule, cybercriminals disguise themselves as legitimate and reliable sources, including representatives of banks, technology companies and retailers. The goal of attackers is to convince victims to click on a link or open an email attachment. After that, users are taken to a fake site that asks for certain personal information, such as credentials or financial details, or stealthily downloads a threat to the device.
2. Dangerous downloads and malicious ads
In some cases, visiting an infected site or resource with dangerous ads can lead to the download of malicious software. As a rule, well-known sites are not attacked due to stronger protection, but this is not always the case. Therefore, it is important to use a computer and laptop security solution that will provide protection against online threats, as well as to check that the browser privacy settings are correct.
3. Digital skimming
Hackers can also compromise the payment pages of e-commerce sites with a malicious application that collects card data as the user enters it. This type of threat is difficult to defend against because the issue is with the ISP. However, shopping on trusted sites can reduce the risk of data being stolen by hackers.
4. Malicious programs and files
Cybercriminals also disguise malicious software as legitimate-looking programs. Most of these applications are available on online forums and other third party platforms. Therefore, you should only download software from trusted sources and use an effective solution to check for malware on your device.
How to improve computer security
- Set up automatic updates for the operating system and all applications on your computer.
- Check your device for unknown apps and uninstall apps you don’t use. Because the fewer applications on the computer, the lower the likelihood of their vulnerabilities being exploited by attackers.
- Install a layered computer security solution.
- Set up and perform regular backups of data to be stored on a separate device.
- Protect your browser by adjusting your privacy and security settings and making sure you have the latest version.
- Enable and configure the firewall on the OS and home router, and check that its settings are correct, including setting a strong password.
- Use multi-factor authentication to protect accounts from being stolen by phishing attacks and other threats.
- Avoid using unknown USB drives as they may contain malware.
- Use a password manager to save unique credentials that are hard to break.
- Only download apps and files from trusted sources, and avoid using pirated content, which can often spread malware.
However, even after following all these recommendations, the risk of infection by online threats remains. Therefore, always be careful not to reply to unsolicited e-mails and online messages, and make sure that important data on your device is properly protected, in particular with an encryption-enabled solution.
