What is Ransomware?
The explosive rise of the Internet and Digital Technology has seen our lives, businesses and information connected like never before – and with it has also grown the dark world of Cybercrime and Cyber Attacks.
While there are numerous kinds of Cyber Attacks, Ransomware is arguably one of the most nefarious. This is because Ransomware bases itself on a corruption of the field of Cryptography – the practice and technique of securing communication channels, resulting in Cryptovirology. It distorts and violates the techniques and tools of Cryptography and devises powerful forms of Malware including Ransomware and Asymmetric Backdoors.
Ransomware once unleashed, threatens to publish a target’s personal data or worse still, permanently block the target’s access to his/her own data – unless the target pays a ransom. It can thus be used to mount extortion-based attacks that cause loss of access to information, loss of confidentiality, and information leakage, tasks which cryptography typically prevents.
How Common is a Ransomware Attack?
The first documented Ransomware was in 1989 and was known as the AIDS Trojan. The AIDS Trojan was a DOS Trojan Horse, whose payload encrypted the names of all the directories on drive C: Since then, though, the scale and complexities of Trojan-styled Ransomware have increased exponentially. Statistics reveal that the first 6 months of 2018 saw close to 200 million Ransomware attacks globally – a 229% increase over the same time frame in 2017. A report by SonicWall claimed that in 2021, the number of such attacks was around 623 million.
What makes Ransomware so dangerous is that it is designed to spread across a network and target database and file servers, and quickly paralyze an entire organization. Every year It generates billions of dollars in payments to cyber criminals and inflicts significant costs and damage on businesses and governmental organizations.
The unfortunate and brutal truth is that if you are a modern business, there is almost no way of avoiding ransomware attacks. Even the best malware protection and cyber infrastructure, cannot completely guard against ransomware infections. However, that doesn’t mean that there is nothing you can do.
Here are a few essential steps that you as a business must take to mitigate the impact of Ransomware Attacks and keep your business and customer data safe and secure.
1. Nothing can beat a good ‘Backup’
One of the most dangerous types of Ransomware is called Encrypting Ransomware. A business that falls prey to such an attack, will be able to browse through its own files but not be allowed to open or access any of them – thus in a sense making the infected files almost completely useless. The only safeguard a business can have against such an eventuality is a ‘Defensive Approach’ – whereby, each of the files has a secure backup.
It is important to note however that the backups must be stored in such a way that they do not also fall prey to Ransomware. This is why it is important to have a minimum of 3 or sometimes even 4 backup copies of all critical business data also stored across different media formats – SSD drives and Cloud Storage.
It is also very important for any business to keep updating its OS and software to their latest configurations, such as using the latest forms of Windows, etc.
2. Curiosity kills the Cat
Ransomware attacks most often depend on weak links within an organization’s chain to infect critical data. The most common forms of Ransomware use phishing emails that contain malicious attachments. The victim’s entire system can get infected if even one member of the team naively visits a harmful website or downloads and installs malware without knowing.
This is why one of the principal steps for an organization in combating Ransomware is staff training. Employees, particularly those linked to the main server and those handling critical data, must be trained to identify emails that seem ‘fishy’ or suspicious. The staff must also be trained to report any mistake (accidental or otherwise) to the IT department at the earliest, as early detection can help control the spread of Ransomware and the damage it can do.
Another very important detail that an organization must always insist on its staff on is that for any software or installations, only authentic links be used. The risk of Ransomware goes up exponentially in cases of downloading software or media records from unknown places.
A simple protocol that all staff must always abide by is to ensure that the browser address bar of the page uses “https” in place of “http”. A protection or padlock icon in the address bar can also designate that the page is safe.
3. Firewall Technology/Web Application Security and constant monitoring
The only way an organization can create real ransomware protection is by installing a network firewall, with progressive threat defenses. The Barracuda CloudGen Firewall is an example of such a network, as it scans all network circulation for possible ransomware, malware, and other cyber threats to the network.
The Sophos XG Firewall works on slightly different parameters by offering network defense against ransomware and other progressive threats, including crypto mining, bots, virus, hacking, exploits, and APIs. XG Firewall also offers an easy, elegant way to manage RDP and supports the latest TLS 1.3 standard.
4. It is vital to protect Endpoint Devices
As almost 100% of Ransomware attacks always originate from a source that is external to the organization, Device Endpoint Protection is very effective against such attacks. Staff must be trained to never attach any kind of USB key or Storage Media to any computer in the organization – if they cannot trust the source of said storage device. Another ‘best practice’ is to ensure that the OS is always kept updated. Every effort must be made to make it as difficult as possible for Cybercriminals to inject malware into the system.
5. As with everything else in life, ‘Hygiene’ is key
Even though cyberattacks and ransomware are becoming increasingly complex and sophisticated, Cybersecurity experts are unanimous in their belief that most of these attacks can be warded off just by practicing good Cyber Hygiene.
Even if your organization lacks the means or resources to implement very advanced cyber security protocols, creating an environment of ‘cyber resilience’ and good online behavior amongst the staff is critical for the basic safety of the business.
It is important to provide regular security awareness training for every member of your organization so they can avoid phishing and other social engineering attacks. Conduct regular drills and tests to be sure that training is being observed.
The staff must also be trained to only use secure networks and avoid public Wi-Fi networks, as many of them are not secure. An organization that handles data on its customers must also consider installing a VPN, which provides a secure connection to the internet, regardless of location.
