Introduction to Ransomware and How to Protect Yourself from This Threat

A massive cyber-attack has wreaked havoc and hit millions of computers on May 12th. A wide assortment of universities, hospitals, companies, and governments in more than 150 countries was hounded by this cyber-attack.

It infected targeted computer systems and demanded ransom in return for unlocking the systems. According to Chinese State media reports, this malware has affected more than 40,000 businesses and institutions including Britain’s health care providers (NHS).

What is Ransomware?

Known as one of the most malicious computer malware, Ransomware is designed to block access to the computer systems and demand ransom in return for its recovery. This malware holds a computer hostage and provides the decryption key only after a sum of money is paid by the victim. Ransom is paid in bitcoins so that the identity of the cybercriminal is kept hidden and concealed. It is observed that in all these recent ransomware attacks, money demanded by the attacker was approx. $300 to $1000 per machine.

How is ransomware delivered?

Ransomware is known to be one of the most critical issues when it comes to IT security and concerns. Reports say that a majority of ransomware is transferred through the web and more specifically through phishing emails. These fraudulent emails include attachments which, when opened by the user infects the targeted computer and blocks its access.

Majorly, there are two types of ransomware:

  1. Encryptors – It uses state-of-the-art algorithms for blocking system files and thereafter, asks for payment in order to decrypt the data. Examples of such ransomware include Locky and CryptoLocker. Encryptors are the most widespread and destructive ransomware.
  2. Lockers – When a user is locked out of his or her operating system and access to their files is blocked, the ransomware used is known as lockers.

Both these types of malware encrypt the computer data and make it impossible for the user to access the files until the ransom is paid. If you deny offering the initial payment within the given period of time, then the payment amount increases and you get a warning regarding the permanent and possible destruction of the data (in case of non-payment).

Does antivirus detects and protects the data against ransomware?

Standard antivirus software aren’t strong enough to protect computers from the latest versions of malware. If an individual installs a free antivirus software, it is most probably not equipped to safeguard the device.

Sometimes a paid and valid antivirus can also fail to detect the ransomware. Malwares are backed by potent evasion tactics that allow them to – dodge cyber security professionals, stay secure and undetected by antivirus tools, and stay hidden from law enforcement agencies.

Prevention methods

When we talk about Ransomware, awareness, and prevention are the two best strategies to combat the attack.

It is much easier for the cyber criminals to attack home users because they don’t have the data backup. Hence, if their devices are locked, then they have to pay ransom to get important data (pictures, documents etc.) back. Users are unaware of cyber security solutions and rely completely on antivirus software which does not provide comprehensive protection against ransomware.

Most of the time businesses are on the topmost list of cyber attackers as multiple machines can be affected through the same network.

To make sure that your business remains safe and untouched by malware, one should emphasize on the following prevention methods:

1. Backup your Data

Considering the fact that ransomware has attacked more than 40,000 businesses throughout the world, every company should make sure to have at least 2 copies of their crucial data on different mediums or platforms. In this case if any malware affects your computer, then at least the critical data can be retrieved for future use.

Either you can keep a copy of your data on external drives and USB drives or on the cloud. Also, while saving it on the cloud, make sure that the auto sync option is not always on as it increases the risk of transferring infected and scammed files from your personal device to the cloud. Get well-versed with the Microsoft’s new security updates.

2. Updating PC is very necessary

Ransomware attacks have created chaos in the IT sector. It has been noticed that these recent attacks primarily affected systems that had the old Windows operating systems such as Windows XP etc. You can protect your devices against such threats by updating the operating systems on a regular basis.

Install the official Windows patch (MS17-010), which closes the SMB Server vulnerability used in this ransomware attack.

3. Use cloud-based SaaS digital workplace solutions

Cloud-based solutions enable businesses to externally host applications where it is the responsibility of the vendor to handle data storage, backup, and security. Cloud solutions and SaaS providers endeavor to invest in security solutions for providing the best possible services to the business owners. It not only keeps your critical business data safe from hackers and cyber criminals but also enhances productivity and efficiency.

In this tech-driven world, a wide number of organizations are seeking business communication and productivity tools that can help them achieve their goals. There are many digital platforms that are created to drive productivity, improve efficiency and support mobility and security. Here are some of the security benefits of these applications:
