Understanding Ransomware

Ransomware is a generic name for a family of computer bugs programmed to lock up endpoints, such as PCs, servers or mobile devices, in various ways. Ransomware encrypts data on the endpoint or revokes access to the endpoint itself, then asks the victim to pay a ransom to regain control of the endpoint. A ransomware attack can affect an individual or organisation anywhere in the world.

How can Northdoor’s ‘Protect IT’ solutions help your organisations against Ransomware?

Northdoor researched more than 40 ransomware strains, including Locky, Cryptowall, TeslaCrypt, Jigsaw and Cerber and identified the behavioural patterns that distinguish ransomware from legitimate applications.

Whether a criminal group or nation created the program, all ransomware functions the same way and encrypts as many files as possible. Ransomware can’t determine which files are important, so it encrypts everything based on file extensions.

The Northdoor Ransomware solution

Northdoor has developed a Ransomware protection solution that takes all these challenges into consideration. Our defence solution detects Ransomware as soon as encryption occurs either on a computer or network drive. Once encryption is detected, we suspend it, warn the IT department, and display a popup that warns users their files are at risk and enables them to stop the attack.

Our Ransomware defence solution will also educate your users on the signs to watch out for when they are under a ransomware attack. Both of these things together ensure that you have the best defence possible against ransomware attacks.

Remember, it only takes one employee on the network to execute ransomware, potentially affecting the entire company and stopping your business in its tracks.

 

Ransomware isn’t subtle

Most malware silently persists in the network, carefully surveying the network surroundings, awaiting instructions or the right opportunity to attack your systems. These programs mask their actions to evade detection and attempt to gain elevated privileges.

Ransomware, on the other hand, wants to be discovered. As soon as the program starts encrypting files, it reveals itself to the victim and demands a hefty ransom, many times along with various threats.

Our research into ransomware protection shows that while there are some very sophisticated strains, many are crude and poorly written. But just like an improvised weapon, the less refined strains are easy to produce and can be extremely effective.
A piece of malicious code that promotes its existence up-ends the way most traditional anti-malware and anti-virus products work.
You may think that lacking intricate malicious mechanisms makes ransomware easier to detect. But in practice, those mechanisms are often weak spots that make other types of malware stand out.

 

Ransomware doesn’t need to be accurate

Ransomware just wants to cause as much damage as possible. It doesn’t need to encrypt all of your files to be successful – it just needs to scramble enough important ones. Ransomware grabs and encrypts anything: quarterly revenue spreadsheets, Word documents, PowerPoint presentations, photos. And the list goes on. Ransomware fires in all directions and hopes to hit something important. This lack of specificity makes ransomware more difficult to detect. You can’t concentrate on defending only certain locations or applications. You have to monitor everything, all the time.

Ransomware is alarmingly quick

Ransomware takes between 5 and 20 minutes to encrypt every relevant file on the average hard drive. That means that even the slowest, single-threaded ransomware can encrypt numerous potentially important files in seconds. Since Ransomware works quickly, detection and response time is of the utmost importance, which may be problematic for certain behavioural-detection solutions. Unlike detection based on what-the-code-is, detecting malware based on what-the-code-does is prone to false positives and requires collecting additional evidence before a verdict is reached. This leads to systems being compromised with ransomware on a daily basis.

Northdoor offers a full threat-analysis exercise, covering all major aspects of IT security and data protection.

Organisations today face a complex array of IT security and data protection risks. Cybercrime is on the increase, particularly as companies open up their systems to partners and customers, and legislation such as the GDPR places a heavy burden on organisations to understand and manage their data better.

Northdoor’s expert Security practice offers a consultant-led Threat-Analysis Exercise to help organisations understand today’s threat landscape, compare their current capabilities with those of their industry peers, and plan a best-practice enhancement programme. By showing you where and how to invest, we can accelerate your legislative compliance, strengthen your cybersecurity posture and improve your data governance – rapidly and cost-effectively.
