Ransomware, a malicious software or malware, is a technique used by hackers (cybercriminals) to encrypt documents on a PC, lock out the user, and demand a ransom to regain access to the data on the computer.
This type of malware can typically enter a PC either through an email attachment or directly from a browser, if a website infected with it is visited. It is also able to access a PC data through a network.
In recent years, extremely malicious ransomware attacks were caused by malware such as WannaCry (WanaCrypt0r 2.0, or WCry) and NotPetya. WannaCry was a type of ransomworm, a piece of malware that can self-replicate, and continue to grow exponentially, just as a real disease does.
NotPetya was different in that it didn’t seem it was created to make money as other ransomware does. Even if users did pay, their data could never be recovered. NotPetya seemed to be a deliberate, malicious, and destructive attack.
These two wreaked havoc across the globe in 2017. They sparked so much alarm that more people than ever before had good reason to back up their files. Backing up files effectively deadens a ransomware attack. Even so, too many of us have short memories and cybersecurity experts warn against getting lazy about backing up files.
What is surprising is that ransomware in nothing new. The first instance of its threat was detected over 30 years ago in 1989, when an AIDS conference was ‘attacked’ by floppy disks.
Early ransomware contained a warning from the FBI, attempting to trick unknowing users into paying a fine or they would be accused of trafficking in child abuse imagery.
On March 19, 2019, a ransomware attack crippled one of the world’s top aluminum makers in the U.S. and Europe, Norsk Hydro. The company is one of a handful that produce end-use products for aluminum.
The attack had far-reaching consequences. Norsk’s special automated ultrasonic testing systems to precisely scan its products for impurities could not be relied upon, meaning customers such as automakers Daimler and Ford Motor Co. especially, would not be able to use their products.
The task to clean their systems or restore the backups was monumental. The lesson to learn is the more automation introduced into systems, the more and stronger the cybersecurity must be.
Encryption is the innovation that enabled ransomware authors to not only lock up the screen but encrypt all the data. This meant the data would still be locked up even if the user was able to uninstall the ransomware itself. The user had to make the payment in order to get the unlock key.
Cryptolocker, was an example of a piece of ‘cryptoransomware’ found active in 2013 and 2014. Petya has been active since 2016. Other examples of this type of ransomware include Cerby and Locky, among others.
Ever since the first attack, it has been a relentless duel of one-upmanship between the bad guys and the cybersecurity experts and researchers. Unfortunately, ransomware is still alive and well.
The early types of malware did not last long because bank transfers could be tracked and cash payments were hard to pull off. It was the invention of the bitcoin in 2009 that gave the hackers the means to take ransom payment without involving banks.
Ransomware can also attack and lock users out of their Android mobile phones. The open-source nature of the Android operating system makes Android phones more vulnerable to attack. One malware was actually able to avoid detection from Google’s security system and was downloaded in an app from the Google Play Store.
Google cannot control all Android mobile phones, only its own phones, the Nexus and Pixel phones, whereas iPhones are less vulnerable because Apple can push security updates quickly to all its phones at once.
Although many cybercriminals target specific institutions and organizations, the reality is most ransomware attacks are made at random. The criminals will go after anyone with a computer.

WHAT NOT TO DO...
March 31st is designated as globally recognized World Backup Day. It is a day used as a reminder of how and why complete, regular backups deserve a place on the to-do list. March 31st was chosen to remind people to back up or risk losing data and becoming an April Fool!
World Backup Day also includes offers and special deals from many hardware and software companies to mark the date.
