Malware: Types, Detection & Prevention

The word ‘Malware’ is derived from the amalgamation of words malicious and software. It is a type of software that is particularly designed with the sole purpose of harming a target computer system by stealing data or causing disruption. In order to stay protected against malware, companies need to use specific anti-malware programs. But before choosing the correct anti-malware system, it is imperative to know about different types of malware.

Following are some common malware types:

  • Virus: A computer virus is malicious code that has the ability to copy itself and spread to other files and folders. The code attaches itself to legitimate executable programs resent in the target system and launch when the program is executed. Some of the harmful functions performed by viruses are modifying or corrupting files, copying data, disrupting software functions, etc. As the virus is self-replicating, it is difficult to completely remove the virus completely.
  • Worms: Worms are self-replicating and infect computers through vulnerabilities in the operating systems. Most worms are designed to consume lot of bandwidth and overload the servers. However, small number of worms can modify the existing files. Worms are used by the hackers to deliver payloads in target systems which are then launched to steal data, corrupt files, etc.
  • Bot: An internet bot is an application designed to perform automatic functions. Hackers can engineer bots to infect computers and perform large scale DDOS attacks. The bots are programmed to infect multiple computer systems and form a botnet to over-flood the server with a large number of requests. Bots are also used to cause inconveniences like spamming and repetitively showing certain advertisements.
  • Ransomware: Ransomware is a malicious software that completely locks the infected system until the user pays a ransom. Ransomware spreads like a worm across a network and has the ability to infect the network of an organization within hours. Some ransomware software do not lock the entire system, but encrypt critical data files. The users are asked to pay a ransom in exchange of decryption key.
  • Spyware: It is a software that lies undetected in the target system. It’s purpose is to collect information on user activity and send it to the hacker’s server. This is done by monitoring usage, logging keystrokes, stealing user passwords, etc.
  • Trojans: A Trojan is a malicious software that is designed to appear as a common, harmless attachment or downloadable file that may not be detected as harmful by the antivirus system. However, once downloaded, the software executes itself and causes damage such as stealing data, erasing or modifying files, altering system configuration, etc.

Detection Of Malware:

Some common signs that indicate presence of malware are:

  • Slowing down of systems
  • Reduced browsing speed
  • Recurrent freezing of systems
  • Modification of files
  • Altered system settings
  • Missing files
  • Random appearance of new files or applications

Prevention Of Malware:

  • Use reliable & authentic anti-virus
  • Conduct regular scans
  • Do not use pirated software
  • Don’t open attachments from unknown sources

Cyber Security Technologies For Business Organizations

Cyber-crime environment is constantly evolving and cyber criminals are always trying to come with new types of attacks for outsmarting existing cyber security protocols. This emphasizes on the need to recognize and deploy advanced cyber security measures to combat cyber threats effectively.

Here are some reasons that strengthen the need for organizations to invest in advanced cyber security technologies:

  • Cyber-attacks are no longer targeted at merely extracting confidential details or earning quick money. They have moved on to more sinister motives, commonly known as cyber warfare. With increasing connectivity among critical utility infrastructure, cyber warfare has a tendency to grow.
  • Cyber criminals are getting more advanced and the number of sophisticated cyber-attack tools is growing in the deep and dark web.
  • Most organizations keep business-critical data recorded in digital format and are thus greatly dependent on their systems and network. Failure to secure these systems from cyber criminals can endanger credibility, sales, and profit.

Owing to the heating up cyber warfare, organizations need to identify and adopt emerging cyber security technologies constantly. Following is a list of top advanced cyber security technologies that businesses organizations should adopt:

  • Artificial Intelligence & Deep Learning: Application of artificial intelligence in cyber security is similar to two-factor authentication. Two-factor authentication confirms user’s identity based on two different parameters. Artificial intelligence adds additional layers of information and authentication to identity confirmation. Deep learning is used to analyze data such as logs, transactions and real-time communications to detect threats trying to penetrate the system or network.
  • Behavioral Analytics: Behavioral analytics uses data mining techniques to determine patterns of activity across a system and network. This helps in detecting unusual activity such as abnormal increase in data transmission from a device connected to the network. Such deviations from normal pattern can be used to detect potential and real-time cyber threats.
  • Embedded Hardware Authentication: A PIN and password are no longer sufficient to protect hardware, so embedded authentication chips are being used to secure hardware. These powerful chips such as Sixth-generation vPro chips by Intel are embedded in the hardware. The chips employ multiple levels and methods of authentication that work in tandem to ensure authentication security.
  • Blockchain Cyber Security: Blockchain cyber security works on the basis of blockchain’s peer-to-peer network fundamentals. Every member in the blockchain is responsible for verifying the authenticity of data added. It creates a near-impenetrable network to secure organizational data.

IT Security Recommendations For 2021

Rapid growth of technology is changing the way businesses operate. Technologies such as cloud computing, Artificial, Intelligence, automation, and IoT have created numerous growth opportunities for businesses. However, cyber hackers also use these technologies to launch an array of cyber security threats and attacks such as data breach, identity theft, etc.

The rise in number and frequency of cyber threats has created a need for businesses to focus on their IT security strategies. Here are some IT security recommendations for 2021:

  • Cloud Threats: The Coronavirus pandemic has intensified the remote work and collaboration between different teams resulting in increased use of cloud services for data storage, data sharing, app sharing, etc. However, increased migration to cloud has led to higher number of cloud threats. Some common cloud-based security threats are mis-configured cloud storage, reduced visibility and control, incomplete data deletion, and vulnerable cloud-apps.
  • AI Integration: As the cyber security threats keep growing in terms of intensity, AI is emerging as a helping hand to under-resourced IT security teams. Including artificial intelligence in IT security strategy can help in ensuring timely detection of threats and implementing rapid reaction. AI provides threat intelligence by analyzing massive quantities of risk data from structured and unstructured resources.
  • Extended Detection & Response (XDR): In order to ensure data security, it has become essential for IT teams to gain visibility and deep insight into enterprise and customer data across emails, endpoints, networks, servers, cloud workloads, and applications. It is recommended to include XDR in the IT security strategy as it helps in automatically collecting data from multiple sources and correlate it to ensure faster threat detection and incident response.
  • Security Process Automation: High frequency of IT security threats has resulted in a shortage of trained IT staff. Thus, organizations are required to extensively rely on security process automation. These tools eliminate repetitive security operations using pre-established rules and procedures. This also helps in reducing the errors in routine security checks.
  • SASE: Changing organizational environment has transformed the organization’s network security from LAN-based appliance models to cloud-native security service models such as Secure Access Service Edge (SASE). Using this model, organizations can robustly secure remote workforce and cloud applications by routing network traffic through cloud-based security check.
