3 cyber security risks for businesses you’re probably not protected against

Organisations are increasingly vulnerable to cyber security threats due to the reliance on computers, networks, and social media. With increased numbers of employees working from home in the past few years, it is now more important than ever to ensure you are protected against cyber security risks.

You may feel that your organisation is well protected, but there are some lesser-known cyber security risks that you may not be protected against. Most traditional cyber security products are built to act based on common threats. The moment they identify something that is a known malicious threat, they block it. To get past these security systems, cyber attackers are forced into creating new tactics that your organisation is not protected against.

What are the top 3 cyber security risks for businesses you’re probably not protected against?

1. Modified Existing Code

Attackers take an existing threat and make slight modifications to the code as the threat actively transitions in the network, resulting in polymorphic malware or a polymorphic URL. The malware, much like a virus, develops and changes constantly and automatically. If a security product classifies a danger as known and constructs a defence for it based on only one variant, every minor modification to the code will turn the threat into an unknown.

Some security systems use hashing technology to match threats, which generates a fully unique number based on a string of text in such a way that two similar hashes are difficult to obtain. Because the hash value only matches one variant of the threat in this context, any new variant will be considered new and unknown.

To better protect against these threats, security products need to use polymorphic signatures. Polymorphic signatures, which are based on the content and patterns of traffic and files rather than a hash, can detect and protect against numerous variants of a known threat. The ability to detect patterns in changed malware is enabled by focusing on behaviour rather than the appearance of fixed encoding.

2. Recycled Threats

Because attackers regard recycled threats to be the most cost-effective attack tactic, they frequently recycle existing threats using previously established techniques. The limited memory of security products is what renders these recurrent threats “unknown.” Because all security solutions have limited memory, most security teams select the most recent threats to protect against in the hopes of blocking most incoming attacks. If an older danger that hasn’t been detected by the security product tries to join the network, it may be able to get past the security system because it isn’t labelled as something that has been seen before.

It’s vital to have access to a threat intelligence memory keeper, which is generally housed on an elastic cloud architecture capable of scaling to handle the volume of threat data, to protect against these “unknown” recycled threats. If a security product doesn’t have a specific threat recognised and stored, access to the bigger threat intelligence knowledge base could help assess whether something is dangerous and enable the security product to stop it.

3. Newly Created Threats

Attackers who are more motivated and ready to put money into it will construct a completely new danger with completely new code. For an assault to properly be deemed a previously unknown threat, all components of the cyber-attack lifecycle must be new.

Turning unknown threats into known threats and actively preventing against them happens in a combined environment. To begin, you must forecast the next attack step as well as its position. Second, to stop it, you must be able to quickly construct and supply protection to the enforcement point.

When a truly new threat enters your organisation, the first line of defence is having cybersecurity best practices that are specific to the organisation. At the same time, you should be sending unknown files and URLs for analysis. To do this, your organisation should automate protections.

The effectiveness of this analysis depends on the time it takes to provide an accurate verdict on an unknown threat and to create and implement protections across the organisation. Your security posture must be altered quickly enough to prevent the threat from progressing – in other words, as soon as feasible. To prevent the danger from spreading further across the network, preventions must be built and deployed automatically across all security products faster than the threat can propagate.
