Some of the most frequent and severe cyber security attacks ever recorded against companies in a variety of industries in the last couple of years. The threats we face from hackers, viruses, malware, and data breaches are not going away— they are evolving, and there is much more to come as we approach 2019.

Asking the smartest people I know and basing our scenario on threats, because they traditionally show the most innovation in breaking security, here are our main ‘predictions’ of what might happen in the coming months.

Ransomware is when an intruder accesses your computer, encrypts important files with a private key and requires a ransom to decrypt the information. Ransomware has been the key threat to cybersecurity for the last few years. For years to come, it will be just as much, if not more, a problem and show no sign of slowing down.

Since ransomware is a form of malware, the same defensive strategies are required–antivirus software, updating software with the latest security patches, and training phishing attacks to recognize employees.

Additional protection is essential– reducing the impact of data loss by using a recovery strategy for backup and ransomware or keeping data in multiple, replicated locations.

Business can thus continue uninterrupted, without paying the ransom.

A botnet is a collection of devices connected to the Internet that can include PCs, servers, mobile devices and the Internet of devices that are infected and controlled by a common malware type. Users often do not know that a botnet is infecting their system.

They are used to start massive attacks, including millions of Zombie computers at times. Botnets are controlled by the hacker’s Command and Control (C&C) networks. They can be used to launch attacks on Distributed Denial of Service (DDOS), to make a target website so busy that legitimate requests can not be processed.

Your best defense against botnets is to make sure that the viruses and worms do not compromise your machine.

Usually, people do not know that their machine was infected until it was too late. Regular scans with robust and up- to- date antivirus software are therefore a must.

Phishing attacks are a form of social engineering attack designed to steal user logins, credit card credentials and other types of financial personal data. In most cases, these attacks come from a trustworthy source.

The information is sent directly to its malicious source once you reply to a phishing email or follow its instructions. You can then use this information to make purchases.

Most people who use the Internet will experience at least once a phishing attack— they usually come in the form of spam e-mails — so it is only vigilance and caution that can prevent you from falling victim to one.

Common sense is often sufficient to protect you against attacks such as phishing.

Viruses and worms are malicious programs that replicate themselves on computers or through computer networks without the user’s knowledge; any subsequent copies of such malicious programs can also replicate themselves.

Virus infected files infect the machine when opened. Worms, on the other hand, spread throughout your machine and start replicating so that all your files can be infected. Viruses and worms form the building blocks for many more advanced cyber threats.

The installation of anti-malware solutions on the devices can significantly reduce the ability to spread these viruses and worms.

Cryptojacking is a form of cyber attack in which a hacker hijacks the processing power of a target to mine the hacker’s cryptocurrency and significantly affects the power of user systems.

Cryptojacking is used to infect a victim’s computer with a virus that uses hardware resources such as cryptocurrency mine processors.

You should continually monitor and diagnose CPU use and alert to changes over time to defend against these malicious attacks.


2019 is destined to be a further year in which cyber attacks are increasing. They occur more frequently and on a higher scale, using new technologies, advantages, and developments.

However, it’s not really the threats that are changing— ransomware, phishing attacks, and malware still top the list of common threats to cybersecurity. Due to the increase in the number of devices and lack of awareness, we are much more available to threats.

As always said, KNOWLEDGE is the biggest defense against any cybersecurity threat. Always use antivirus software of good quality and keep away from spam emails.
