To learn more about the cybersecurity training we offer, please visit our training page.

What is Cyber Security?

Cyber security also referred as information technology security is a technique to protect and safeguard internet connected cyber space i.e., systems, networks, devices, programs and data from unauthorized access. 

What are Cyber Security Threats?

Any unlawful and malicious attack by an individual or organization to damage or steal or disrupt a digital system is a Cyber security threat also known as Information security threat.Information threats can emerge from various actors such as corporate spies, hacktivists, terrorist groups, hostile nation-states, criminal organizations, lone hackers and disgruntled employees.As cybersecurity threats continue to evolve and become more sophisticated, enterprises must think of the types of security threats they are dealing with.

Motives Behind Cyber Attacks

  • To seek financial gain by hacking banks and commercial institutions.
  • To attack critical assets of a nation/state
  • To penetrate into both corporate and military data servers to obtain plans and intelligence.
  • To hack sites to virally communicate a message for some specific campaign related to politics, Nationalism as well as Terrorism. 

Top 10 Types of Cyber Threats

Below is a detailed explanation of each type of cyber security threats:

Malware Attack

Malware is a malicious software which is activated when a user clicks on a malicious link or attachment leading to installing dangerous software. 

Once installed, malware can monitor user activities, share confidential data to the attacker, assist the attacker in penetrating other targets within the network, and even cause the user’s device to participate in a botnet leveraged by the attacker for malicious intent.

Malware Attack Involves:

Wiper Malware - It is a type of malware which tends to threaten the system by overwriting the files or completely crashing an entire device through manipulation. Such software is generally designed to send and create communal disturbance through politically sensitive messages, organizations crucial, valuable documents and country’s secret assets.

Worms – A malware that can self-replicate without any human interaction. A threat actor can spread the malware across the network through this technique.

Spyware – It is a type of obnoxious software which helps malicious actors to gather unauthorized data including company patent formula, Individual payment details and personal data. Spyware largely affects mobile phones, desktop applications, web browsers etc. 

Trojan virus – Trojan is a malicious software which pretends to be legal and normal as other software but hides through apps, browser extensions, games or email attachments. Downloading such a virus unknowingly leads to further devastation and complete breaking down of the device.

Ransomware – An organization or individual is being denied access to its own networking system or data via encryption and in exchange demands a Ransom to be paid to restore access of assets. There is no complete guarantee that the owner would be able to restore his/her whole data after successful payment.

Fileless Malware – This type of threatening software does not require installation or download, instead get access to the intended system through native files like Power shell and WMI being editable and represented as legitimate and undetectable.

Rootkits – Rootkits are super imposable software which are injected to a targeted or intended networking application, operating system kernels or hypervisors leading to give key and ultimate administrative control of the entire system. In such cases an attacker or hacker can operate in a congested environment to make him/her unrecognizable or unidentified.  

Social Engineering Attack

Socially induced attacks are mainly where the user is psychologically manipulated according to the attacker's desire and intention so as to get consent to misuse one’s information.

It generally contains the followings such as:

Honey Trap- In such circumstances social workers create fake identity and accounts to attract a target user online. Through continued online relationships, social attackers try to get important and sensitive information.

Pharming- It is an online fraud scheme through which a hacker consciously installs malicious code and software directing users automatically to unwanted and fake websites enabling them to provide personal data.

Scareware Security Software- Such software pretends to be a security scan for malware but regularly shows unprecedented warning and detections. Cyber criminals may ask to pay in order to remove warnings which ultimately lead to being shown off the user financial details.

Phishing- In such attacks criminals may share fake codes that seem to come from legitimate and legal sources such as email, browser extensions etc which directs one to perform certain actions such as accepting cookies, accepting terms and conditions which may lead to exposing sensitive information.

Vishing- Through vishing or voice phishing numerous attackers may access one’s financial information details through mobile phone.

Spear phishing- Phishing which majorly targets security privileged or influential persons to leak crucial and private data.

Whaling- It is a category of phishing where an attacker only targets highly influenced and responsible personnel like Attorney General, Financial advisory secretary, Chief Executive Officers (CEO) etc to enable the intended information.

Drive by Downloads- Malware gets automatically installed or downloaded to a user's system without his consent when exploring unauthorized advertisements or websites through HTTP or PHP on a page. Users are directed to click certain actions by hackers which helps to provide valuable information unlawfully.

Advanced Persistent Threat (APT)

APT is a laborious and sophisticated type of threat where a criminal or group of criminals when they get unauthorized access to a certain platform and become undetectable for a longer period of time against organization’s security radar then try to succumb to a large amount of crucial data. As it demands huge effort and mind set hence mainly done against major religious as well as corporal institutions, nation-state etc.

Major indicators highlighting the presence of APT are

  • New account creation 
  • Abnormal activity 
  • Backdoor/trojan horse malware 
  • Odd database activity
  • Unusual data files 

Password Attack

In certain cyber threats, attackers gain unlawful data and information from targeted individual’s operating systems through guessing the password, social engineering or systematic breach to passwords. 

Password attack may contain the followings 

Brute-force – Hackers in order to get access to data use different software with various passwords by guessing to get a corrected one. Software involves a certain analogy to get a password related to the name of a person and any of his relatives etc.

Dictionary Attack - Certain sets of dictionary common passwords are used in the hope to get a corrected one for target operation.

Pass-the-Hash Attack – Criminal exploits the authenticated passwords and gets a password hash and uses it for authentication of another operating system.

Golden Ticket Attack – Following the same way in the previous attack, a hacker uses the assessed stolen password hash on a Kerberos system to enable the key Distribution center to leak a Ticket Granting Tickets hash. (TGT)

Man-In-The Middle Attack (MitM)

In MitM, a cyber-criminal is assumed to be a middle man between the user and the target system.

Once a middleman is well established, it may steal important information and data, misusing responses and responsibilities and even tries to compromise the user's credentials.

MitM includes following categories of middle man hacking 

  • Session hijacking 
  • Replay attack
  • IP spoofing 
  • Eavesdropping attack 
  • Bluetooth attacks 

Distributed Denial of Service Attack (DDoS)

It is an active variant of DoS where an attacker uses multiple systems in the form of coordinated attack against a particular target system. In such a type of security threat, the users’ resources get overwritten and stop functioning leading to further denial of functions.

As such a threat is created in a combined and compromised form hence easily being undetected against High security systems.

DDoS Pertains various methods such as

Botnets - Botnets are infected applications with malwares under the control of an attacker. Criminals use similar bots for attacking other targets creating a huge devastation of information.

Smurf Attack - It sends Internet Control Message Protocol (ICMP) echo requests to the user’s IP address which automatically get attached to the victim’s device and infiltrate desired target data.

TCP SYN Flood Attack - In such a type of attack, the attacker sends floods of continuous connection requests with the target system, if the target tries to complete the connection, then the attacker doesn't respond resulting in the user's time out. It immediately fills the connection queue, preventing legal users from connecting with the system

HTTP Flood Attack - Hacker sends HTTP request to user’s system which seems to be legitimate to overwhelm its web server. Such an attack forces the target device to allocate as many as resources to get requisite information.

UDP Flood Attack - In such an attack key host or primary device is flooded with User Datagram Protocol packets which are sent to random ports. UDP further forces cyber victims to search in the affected port and reverse response with “Destination unreachable”.

NTP Amplification Attack - The attacker exploits publicly accessible Network Time Protocol (NTP) servers to overwhelm the target with User Datagram Protocol (UDP) traffic.

Software supply chain attack

It is a type of security attack mainly designed against major organizations intending to target weak and pirated links in its trusted supply chains and software updates. As the supply chain is interwoven with resources, multiple operations, multiple mini networks hence crashing and stealing any segment of the software device may lead to avail unauthenticated data access.

Supply chain attack majorly affects the trusted organizations of the main organization such as third-party vendors and supporting ecosystems.

Types of software supply chain attacks:

  • Malware pre-installed on devices (cameras, USBs, and mobile phones etc.)
  • Compromise of software build tools or dev/test infrastructure
  • Compromise of devices or accounts owned by privileged third-party vendors
  • Malicious apps signed with stolen code signing certificates or developer IDs
  • Malicious code deployed on hardware or firmware components

Injection Attack

To steal information through injecting and inserting certain malicious code or applications. It may lead to compromise of the entire system, expose public information and even execute a DoS attack.

Injection may be of following types 

  • SQL Injection- Structures query language (SQL) injection is a vulnerable category of cyber security threat where a malicious code or application is inserted into the target server. After complete infection the server exposes private and precious information to the attacker. A new variant of this is NoSQL attack.
  • Code Injection- Hacker injects a malicious code to user’s web application without his consent which creates vulnerability to web server exposing its privacy.
  • OS command Injection- Criminal exploits the input command of a target user’s application or web server for its own desirable execution which may create serious digital vulnerability.
  • Cross-Site Scripting (XSS)- Cyber predator intends to put strings of texts with unauthenticated Java script in users web browser. Web server directs to implement the code re-enabling users to utilize the malicious website and ultimately share important personal information.
  • LDAP Injection- In such an attack hacker provides characters to alter Lightweight Directory Access Protocol (LDAP) queries. A system or application becomes vulnerable if it utilizes unsanitized queries. 

Cyber Espionage

Cyber espionage or Cyber spying is a kind of cyber threat where a malevolent user tries to get highly classified or sensitive data, Intellectual property for financial advantage, competitive gain, political or religious manifestation.

Cyber spies Majorly attempt to access the following properties:

  • Business goals, strategic plans and marketing tactics
  • Research & Development activity
  • Client or customer lists and payment structures
  • Salaries, bonus structures and other sensitive information regarding corporate finances and expenditures
  • Military intelligence
  • Academic research data such as product formulas or blueprints
  • Political strategies, affiliations and communications
