Ransomware Attacks Examples: Learning from the Past to Protect Your Future.

Ransomware attacks have increasingly become a menace to both individual persons as well as many organizations around the world. These attacks involve hijacking information by encrypting it and requesting a ransom for the retrieval of the information which causes major interruptions and financial losses. As we review these events, we can also learn their lessons which will help us in future attacks. In this discussion, the recent past infamously known attacks will be highlighted below.

1-WannaCry

In our graph, WannaCry Ransomware attacked more than 200000 computers in May 2017 in 150 countries. During this attack, users’ files on their Microsoft Windows operating systems were held hostage until they paid a ransom in Bitcoin. Specifically, it can be noted that the attack brought the operation of several key organizations such as National Health Services (NHS) of the United Kingdom to a standstill.

Key Points:

Spread: Used Windows vulnerability to launch its attack.

Impact: Over two hundred thousand computers were impacted globally.

Notable Victim: NHS or National Health Service.

2-Petya/NotPetya

In June of the year 2017, the world experienced the Petya ransomware now known as NotPetya. While the majority of ransomware is created to receive a payment, NotPetya was aimed to create as much chaos as it possibly could. Petya utilized the same Windows exploit method as that of WannaCry and propagated using infected software updates. It was aimed at large enterprises as well as critical infrastructures such as the Ukraine’s electricity supply system.

Key Points:

Attack Vector: Compromised software updates.

Impact: Massive interruption of key inter-connected infrastructures.

Notable Victim: Power grids in Ukraine and global business giants.

3-Ryuk

Ryuk ransomware was first seen in 2018 in the month of August, it is known to be highly selective with its victims. This kind of ransomware is frequently used against industries with prominent stature, this is done through attacking using spear phishing emails or exploiting RDP vulnerabilities. The Ryuk malware encrypts files with malicious code and a ransom is requested, which in some instances is worth millions. Due to its nature f being selective, it is therefore a threat to the medical, education and government sectors.

Key Points:

Attack Vector: Phishing emails and RDP vulnerabilities.

Impact: Hunted major enterprises.

Notable Victim: Regions of various educative and health institutions.

4-Maze

The Maze ransomware that started its operations in 2019 has become infamous due to the double extortion method. Employing Maze operators also composes data; it is known to block that data in case any ransom demand is not met. This change has enhanced the use of bulwark action on the part of the victims thus making Maze one of the vicious forms of ransomware.

Key Points:

Attack Vector: Two forms of attack by encircling and larceny of the affected data.

Impact: More dummies have been taken advantage of to buy off the ransom.

Notable Victim: Every business entity in every business industry.

5-Colonial Pipeline Attack

The month of May in 2021 will be remembered as the month when the Colonial Pipeline ransomware attack captured headlines. This is ransomware that targeted the largest fuel pipeline in the United States, leading to its operations being shut down. The aftermath of the attack was fuel shortages and mass economic damage in the eastern region of the United States. Colonial Pipeline, which spent the cash to acquire ransom of nearly $ 5 million will further limit such attacks on critical infrastructures and their implications.

Key Points:

Impact: Severe fuel crisis in the eastern part of the U.S.

Ransom Paid: circa $ 5 million.

Notable Aspect: Disruption of national security.

Ways to Secure from Ransomware

From this point of view, either the persons or organizations can make an effort toward better protection against ransomware. Filling in all the gaps such as carrying out regular backups and setting up proper antivirus systems and employee education can help prevent it. It is also wise to ensure that systems and software are updated and strong passwords are enforced for added protection.

By foresight, you can help yourself prepare better for these kinds of attacks and take action to improve your security strategies. Always be alert and prevent any possible losses concerning your assets and your normal activities.
