This malware runs in the background and begins to use the computer’s processing power to solve complex mathematical problems that generate digital currencies, such as Bitcoin or Monero. PowerGhost is one example that utilises the computing power of infected systems to mine cryptocurrencies. It can also compromise the security of the system by facilitating other types of attacks and stealing sensitive data.
PowerGhost is an instance of such malware operating silently in the background, utilising the processing power of compromised computers to solve intricate mathematical problems that generate digital currencies like Bitcoin or Monero. Additionally, it poses a risk to system security by enabling other forms of attacks and potentially exfiltrating sensitive data.
By using browser extensions that block cryptocurrency-mining scripts, you can significantly reduce the risk of your system being infected with crypto-mining malware.
Logic Bombs
Logic bombs are a potent threat that can be challenging to detect since they can remain hidden on a system for an extended period. They can be created and inserted into software by malicious insiders, such as disgruntled employees or contractors, or by external attackers who have gained unauthorised access to a system.
Logic Bombs are malicious code that lies dormant on a system until a specific trigger condition is met. This trigger could be a certain date and time, the termination of an employee, or any other event that the attacker has programmed the bomb to recognise. Preventing logic bomb malware requires access controls, regular security audits, intrusion detection and prevention systems, anti-malware software and security awareness training.
Polymorphic Malware
Polymorphic malware is a type of malware that constantly changes its identifiable features to evade detection by security solutions like antivirus software. Storm Worm a type of polymorphic malware uses advanced techniques that involve frequent mutations to its code structure, making it unrecognisable to many detection techniques that rely on pattern-matching or signature-based detection methods. By doing so, the malware becomes unrecognisable to many detection techniques that rely on pattern-matching or signature-based detection methods.
Use advanced security measures like behaviour-based detection, sandboxing, and threat intelligence to detect and isolate polymorphic malware. These techniques can identify and isolate the malware, even if it has changed its appearance and structure, reducing the risk of damage and data loss.
Hybrid Malware
Hybrid malware, also known as combo malware, is malicious software designed by blending different attack techniques to execute complex and multifaceted attacks. This type of malware includes traits from various malware families, including Trojans, worms, viruses, adware, or spyware, to create a single, packaged attack.
Gozi is a hybrid malware that combines the features of a banking Trojan with rootkit functionality, resulting in a potent “banking Trojan on steroids.” This combination enables Gozi to achieve extensive access and control over compromised systems, going beyond typical banking Trojans.
In contrast to other kinds of malware, hybrid malware uses crossbreeding propagation strategies to carry out a number of tasks in a single, destructive operation. Once it has gained access to a system, it can bypass its security, install malicious code and carry out numerous damaging operations simultaneously.
Backdoor
A backdoor is a software created to give a covert mechanism for hackers to break our cybersecurity defences and acquire high-level access to our digital domains, much like a backdoor in a physical building permits burglars to enter undetected. They are typically categorised as a Trojan, which frequently enables them to go unnoticed for long stretches of time, making them very hazardous.
Backdoor viruses can give internet criminals access to your computer and then allow them to carry out a variety of harmful tasks including installing further malicious software on your computer or stealing sensitive data.
Backdoor malware can be defended against by implementing a multifaceted cybersecurity approach that uses firewalls to block unauthorised access, network traffic monitoring to look for indications of unusual activity, trusted anti-malware solutions installed and routine software updates.
Scareware
Scareware is a malicious tactic employed by scammers to manipulate and deceive unsuspecting computer users. It preys on people’s fears and attempts to trick them into downloading or purchasing software that is either useless or altered with malware. In certain circumstances, scareware may serve as a precursor to ransomware attacks; on the other hand, it is designed to bombard users with pop-up alerts without imposing actual damage to their files.
Vigilance and adherence to secure computing practices are essential to protect oneself from scareware and other cyber threats. By remaining aware of potential risks, questioning suspicious messages or alerts and following best practices for secure computing, you can significantly reduce the risk of falling victim to these malicious tactics.
