What are Cyber Threats?
Cyber threats are the invisible dangers of the digital world. These threats exploit vulnerabilities in computer systems, emails, and data networks with the primary aim of compromising, disrupting, or stealing data. Key areas of concern encompass types of cyberattacks and information security, which are all integral to safeguarding against these pervasive digital risks.
There are many real-time cybersecurity incidents around the world. SOCRadar identified a data leak on September 24, 2022, involving Microsoft's misconfigured public bucket, exposing 2.4 TB of data. This incident affected 65,000 entities across 111 countries, with the exposed data spanning from 2017 to August 2022. Microsoft disputed SOCRadar's assessment of the data leak's scale. On September 15, Uber's internal systems were breached. The attacker gained access to HackerOne, Slack, AWS, and GCP accounts using social engineering.
Many companies face cyberattacks, and there are a few organizations actively dealing with these cybercriminals. Let's explore the common digital threats everyone should be aware of.
Types of Common Cyber Threats
Here are some different types of cyberattacks.
Malware - The Silent Intruder: Malware, short for malicious software, encompasses a wide range of threats. These include viruses, worms, Trojans, spyware, and more. Malware can infiltrate your systems through infected files or links, and it can wreak havoc in various ways:
- Spyware: This type of malware stealthily monitors your online activities and can steal sensitive information such as login credentials, personal data, and financial details.
- Ransomware: In a ransomware attack, your files are encrypted and held hostage until you pay a ransom to the attacker.
- Trojans: These deceptive programs appear benign but contain malicious code, allowing hackers to spoof and gain unauthorized access to your system.
- Phishing: Deception is at its best, phishing attacks trick individuals into revealing personal information or clicking on malicious links. Attackers often impersonate trusted entities, such as banks or social media platforms. They create convincing but fraudulent emails or websites to lure victims into their traps. Common phishing techniques include spear phishing, which are highly targeted attacks that focus on specific individuals or organizations, and clone phishing, which is when attackers create a clone of a legitimate email and replace links or attachments with malicious ones.
To guard against malware, employ robust antivirus software and keep your software up to date to patch vulnerabilities.
DDoS Attacks - Overwhelming Your Resources: These attacks aim to overwhelm your server or network resources with an excessive volume of traffic. The goal is to render your website or online service inaccessible. Distributed denial of service attacks can disrupt your operations and cost you both time and money. Implementing network security solutions, such as firewalls and traffic filtering, is crucial to mitigate DDoS attacks.
Ransomware - Pay the Price or Protect Your Data: Ransomware attacks have gained notoriety in recent years. In a ransomware attack, your files are encrypted, and the attacker demands a ransom for the decryption key. Protecting against ransomware involves regularly backing up your data to a secure location, employing robust security controls like intrusion detection systems, and avoiding suspicious downloads and attachments.
Social Engineering - Manipulating the Human Element: Cybercriminals often exploit human psychology through social engineering tactics. These attacks manipulate individuals into revealing confidential information or performing actions that compromise security. Common techniques include pretexting, where attackers create a fabricated scenario to extract information, and baiting, where attackers offer something enticing, such as free software, to lure victims into compromising their security.
Training your team to recognize and respond to social engineering attacks is vital to safeguarding your organization.
SQL Injection - Targeting Vulnerable Databases: SQL injection attacks focus on exploiting vulnerabilities in your website's database. Attackers inject malicious SQL code to gain unauthorized access to your database or retrieve sensitive information. To prevent these attacks, regularly update your web applications to patch vulnerabilities and implement input validation and secure coding practices.
Insider Threats - A Different Kind of Risk: Not all threats come from external sources. They can involve employees, contractors, or business associates who misuse their access to your organization's systems and data. These threats can be malicious, with employees intentionally misusing their access for personal gain, or accidentally, with employees inadvertently compromising security through careless actions.
To mitigate insider threats, establish robust access controls, monitor employee activities, and provide an awareness training program.
Man-in-the-Middle (MitM) Attacks - Intercepting Communication: This involves eavesdropping attacks on the communication between two parties without their knowledge. These attacks can compromise sensitive data or communication. To prevent MitM attacks, secure your network with encryption, use secure communication channels, and regularly monitor for signs of intrusion.
Supply Chain Attacks - A Silent Intrusion: The target is the weakest link in your network's security: the third party. Cybercriminals infiltrate your systems by compromising these third-party vendors. To guard against these attacks, assess the safety measures of your third party and require vendors to adhere to your organization's security standards.
DDoS attacks, while mentioned earlier, deserve additional attention. These network attacks are common and can be detrimental. Employ network security threats such as traffic filtering and content delivery networks to protect your digital assets from DDoS or DoS attacks.
Cyberattacks have distinct characteristics and objectives, and understanding the enemy is the first step to mounting a strong defense. Let's shed some light on cybersecurity and learn about threats and prevention.
