Overview

Safeguard critical data and assets against the latest threats

By infecting computer systems and stealing or destroying data, malware, such as viruses, worms, trojans, spyware and ransomware, is an increasing threat to your business’s cyber security.

Over a third of identified breaches are reported to involve malware, making it important to have appropriate controls in place to detect and respond to attacks before they cause significant damage.

Types

Common types of malware

Virus

A virus is a form of malware that attaches itself to macro-enabled documents and programs in order to infect files and move from host to host.

Worm

A worm compromises hosts by exploiting software vulnerabilities and spreads by replicating itself without human interaction or the need to attach itself to any other program.

Trojan

Trojans, or Trojan horses, are forms of malware that disguise themselves as legitimate software to trick users into executing them on target systems.

Spyware

Spyware secretly installs itself on computers and collects information about its hosts, such as web browsing activity and keystroke logs.

Adware

Adware is a type of program designed to display targeted advertising, which can be used maliciously to swamp users with unwanted ads and popups. Malvertising can also be used to inject malware-laden ads into legitimate advertising networks.

Ransomware

Ransomware is a form of malware designed to cause widespread disruption by infecting multiple systems on a network, locking down machines and demanding a ransom for their return or decryption.

Fileless malware

Fileless malware, or memory-resident malware, writes itself directly onto a computer’s memory to help evade detection and maximise dwell time.

Crypto-malware

Crypto-malware, the malware behind cryptojacking, is secretly installed onto unsuspecting hosts through phishing or browser-based script injection in order to harness computer processing power for the purpose of mining cryptocurrency.

Hybrid malware

The majority of malware-based threats display a wide variety of characteristics, making it difficult to classify them within a single category.

Polymorphic malware

Many types of malware can also be polymorphic – capable of constantly changing their characteristics to avoid detection by signature-based antivirus and antimalware solutions.

Ransomware

The rise of ransomware

Ransomware attacks, in particular, have increased rapidly in recent times and are now a ubiquitous threat to all organisations. By spreading quickly, locking down files and demanding a ransom for their decryption, ransomware is capable of causing significant disruption in a matter of minutes.

The WannaCry ransomware outbreak is just one high profile example of an attack that caused widespread disruption, affecting over 200,000 organisations in 150 countries. Cybercriminals can instigate attacks like these using basic and easily accessible components, highlighting the need for organisations to keep software patched, improve employee cyber awareness and detect malicious activity in its infancy.

Security assessments

Identify and address vulnerabilities

The fast-evolving digital landscape means that new vulnerabilities, and new exploits designed to take advantage of them, appear on a daily basis. One of the most effective ways to stay on top of the latest threats is to perform regular security testing.

As a provider of CREST-approved penetration testing as well as vulnerability assessment, social engineering and red teaming services, Redscan’s ethical hacking team has extensive experience of assessing organisations’ technology, personnel and processes against the latest attack techniques and helping organisations to address them.
