Protection Against Targeted Ransomware Attacks | Antivirus software

 

To protect against targeted ransomware attacks, and Jet Infosystems experts recommend the following actions:

Make a data backup that can be used to recover files in the event of an attack.

Use a security solution with behaviour-based detection technology. It detects Trojans of any type by analyzing their actions in the attacked system. This makes it possible to detect even previously unknown malware.

Check out the site of No More Ransom, an international initiative designed to help victims of targeted attacks recover files without having to pay a ransom. If your data has been encrypted, recommends using the No Ransom service, which presents tools developed by the company to help victims of ransomware.

Conduct an audit of the installed software: not only on workstations but also on all network nodes and servers. Update software in time.

Conduct a comprehensive network security assessment (audit, penetration testing, GAP analysis) to detect and close any loopholes that could be exploited by attackers.

Use external peer review: Consulting with reputable vendors will help you anticipate future attack vectors.

Avoid using accounts with administrator privileges. Create a separate account for computer management, and use an account with elevated privileges in cases when it is really required, for example, to install or configure the software. Most of the everyday user tasks are solved without the "admin" rights. This also applies to home computers, especially those to which children have access, here it is generally better to set up the "child safety" mode since there are various possibilities for this.

Restrict network access to files. Disable or restrict file-sharing mechanisms on your computer. The latest viruses also spread over the network from computer to computer. There, the principle of infection is much more complicated, but this is not about that. For a home network, for the same reasons - the same thing. Do not provide unlimited network access to your computer's drives.

Configure internet browsers. Look at the browser security settings, set the level that will allow you to work comfortably and safely. If the set of sites you regularly visit is not too large, you can significantly raise the level of security without compromising the quality of information display. Of course, saving passwords is not a good idea, and no one does it, but just in case - use complex "master passwords" to protect all your saved passwords, if this option is supported by your browser. It won't help from a specialist, but storing passwords in clear text is really bad. Avoid real-life decoy sites. Check carefully where you enter passwords, card numbers, etc.

Check public Wi-Fi. When using public Wi-Fi, for example in a cafe, make sure that the hotspot really belongs to the cafe, and not just a similar name. See if it has protection (the same "lock"). Also, pay attention to who owns the certificates of the sites you open: the certificates should belong to them, and not to this cafe or someone else. There is no guarantee that a novice hacker will not sit at the next table and will not collect passwords from social networks or spread the same WannaCry virus to visitors' laptops.

Do not open suspicious emails ( phishing ). The most important thing is to protect your data, it is on them that all kinds of ransomware, ransomware and other malicious software are aimed. Considering that the cheapest and most efficient way to deliver malicious content is via email, use common sense when receiving correspondence. Consider that everything you get from the outside is more likely to contain a virus. then does not contain. A letter from any suspicious or unknown address is a reason to delete the letter without reading it. In everyday work, a certain skill is developed, even visually you can distinguish addresses, say, partner.ru from partner.ru.com or the nested Account.docx from the executable file Account.docx. ______. exe or links to the script HTTP: // somewhere and there. Invoice.pdf.js. It is important to remember that if the "bank", "tax", "customer", etc. urge you to send a letter to urgently do something with an attachment, open a file or go to a certain site - be extremely wary of this. By the way, sometimes on the street right in front of the office you can find a "lost" flash drive, there is also such a method of distribution.

Provide cybersecurity training for employees. Particular attention should be paid to engineering and technical personnel, their awareness of attacks and threats.

Provide protection for both the corporate network perimeter as well as outside. With the right security strategy, significant resources are devoted to detecting and responding to attacks before they reach critical targets

Be wary of files you download on the Internet.

"And there is a hole in the old woman" - no one guarantees that by downloading the program, even on a well-known and respected site, you will not pick up another Trojan. New viruses come out faster than protection against them, and the antivirus software of websites may well “miss” another cunning virus.

It is especially unsafe to download files from peer-to-peer networks, as well as bring them on a flash drive from nowhere. There is only one piece of advice - be sure to scan all new files with your antivirus or an integrated protection system, and if you suspect that such a system is failing, 

Don't believe what you read!

If you read on the Internet that Alla Pugacheva married Barack Obama, then first of all look at what kind of site it is that wrote this news. Does it belong to the "yellow press" or humour?

Just type this query into a search engine and read what others have written about it.

Also, do not believe the first reviews you come across for any product or product. Read a few - there are always good reviews and not. Analyze if the purchase is serious. Often, comments are of a custom-made nature. 

Good quality antivirus.

Before you start using your computer and the Internet, be sure to take care of installing high-quality and time-tested antivirus software. There are a lot of them, and here you can advise at your discretion, feedback and a practical approach to this issue.

When you connect any external device to your computer, for example, a USB flash drive, then always check with an antivirus so as not to infect your computer. Check your computer periodically - run a scan.
