As we look into 2024, let's explore the top cybersecurity threats and how to protect data against them.
What is Cybersecurity?
In simple terms, cybersecurity is protecting computers, computer networks, mobile devices, various electronic systems, communications, and data from malicious attacks. It is also known as information technology security, electronic information security, or simply IT security.
Current Cybersecurity Landscape
According to a shocking report by Cybersecurity Ventures, the cost of cybercrime reached $8 trillion in 2023, which means over $250,000 per second—a considerable amount of money, right? The alarming situation is that the amount is expected to rise to $10.5 trillion by 2025. This immense financial impact highlights the critical need for organizations across industries to be prepared against evolving threats, ensuring resilience and security. Current cyber security threats involving malware, phishing, machine learning, artificial intelligence, and cryptocurrency place the data and assets of corporations, governments, and individuals at constant risk. The shortage of cybersecurity professionals also worsens the situation, making the stakes higher than ever.
Types of Cybersecurity Threats
As digital landscapes evolve and advance, so do the types of cyber threats that target them. There are so many types of it, and each year, there is an addition of these threats; as security advances, the scammers also find some loophole to attack. These Security threats can be broadly categorized into several types, each with unique characteristics and methodologies:
Human Risks
The biggest risk in cybersecurity is often not the technology itself but the people who use it, who are considered the weakest link. Human risk is regarded as a top cybersecurity threat because humans play a central role in organizations' operational and security processes.
The most common human risks involve careless behaviors at the workplace, such as using weak or reused passwords, failing to secure physical devices, mishandling sensitive information, or downloading malicious software by mistake. Poor security hygiene and insider credential theft can leave organizations vulnerable to exploits and attacks. People don't read the terms and conditions of software and websites, so there is always a chance that a person can unintentionally give way to scammers by giving permission.
A recent study by the security firm Mimecast found that human errors are the biggest cyber security risks for businesses. The report highlights that in 2023, over 70% of cyber breaches were caused by mistakes made by people. These included incidents where credentials were stolen, identities were compromised, social engineering tactics were employed, and access privileges were misused.
Malware Threats
Malware continues to evolve, becoming more complex and stealthy, making detection and mitigation challenging. Due to its wide range, financial impacts, and potential for data thefts, it is considered one of the biggest cyber threats. Some top malware threats include viruses, worms, ransomware, crypto-jacking, and file-less malware.
Viruses and Worms:
Though some of the oldest types of malware, viruses, and worms are still effective, viruses attach themselves to clean files and spread, causing damage. Worms can replicate themselves and spread through network vulnerabilities without human help.
Ransomware:
Ransomware is increasing in 2024. Hackers usually attack the education sector, healthcare institutions, and the finance sector. Ransomware attacks involve encrypting the victim's data and demanding payment for decryption. They can paralyze critical systems and require a large amount of money to resolve. Ransomware as a Service (RaaS) has made it easier for criminals to launch these attacks more frequently.
Cryptojacking:
As we all know, digital currency is in demand, and crypto-jacking uses your computer's resources to mine cryptocurrency without your knowledge, slowing down your system.
Fileless Malware:
This malware doesn't use files to execute its attack. Instead, it utilizes legitimate programs to carry out its harmful activities, making it harder for traditional antivirus programs to spot.
Social Engineering Attacks
Social engineering uses human interactions to gain unauthorized access to critical information and systems. Phishing is one of the most common examples, where attackers try to fool users into sharing personal details, login information, or OTP.
Phishing
Phishing is one of the most used cyber attacks. Attackers trick people into giving up sensitive and personal information. Through this method, they try to access personal information like login credentials, debit or credit card details, and other bank-related information by pretending to be concerned company authorities. Variants like spear phishing(targeted attacks), vishing (voice phishing), and smishing (SMS phishing) are becoming more sophisticated and complex to detect.
Baiting and Pretexting:
We all are frustrated by spam calls and receive fake offers and lotteries, usually from scammers. Baiting involves enticing victims with promises of goods or information, while pretexting involves attackers pretending to be someone else to gather personal information.
Business Email Compromise (BEC):
Almost all businesses revolve around emails, and scammers are taking advantage of this. Also, email addresses are easily accessible, and scammers use email fraud to trick companies into sending money or sensitive data to criminals.
Network and Application Attacks
These attacks target the core of IT infrastructures:
Distributed Denial of Service (DDoS)
DDoS attacks overload systems with internet traffic, disrupting services and acting as a distraction while more severe attacks are carried out in the background.
Man-in-the-Middle (MitM) Attacks
MitM attacks occur when someone secretly intercepts and potentially alters the communication between two parties or between a user and an application to steal or manipulate information. They often exploit SSL/TLS protocol flaws.
Injection Attacks
SQL injection, code injection, and OS command injection involve sending untrusted data to an interpreter, executing unintended commands, or accessing unauthorized data.
Digital Infrastructure Threats
As technology advances, new challenges arise in IoT, supply chains, and cloud computing:
IoT Attacks
IoT devices often lack robust security, making them easy targets. Once hacked, these devices can be used to create botnets for DDoS attacks.
Supply Chain Attacks
Supply chain attacks involve tampering with software or hardware before it reaches the consumer. Attackers exploit trusted relationships to sneak in harmful code or components.
Cloud Security
Misconfigurations in setting up cloud services or poor access controls can result in unauthorized access data breaches.
State-sponsored and Insider Threats
Due to technological advancements, the war between the two countries has also shifted towards online by using the internet, also called the Fifth Generation war in broader terms. These threats pose sophisticated challenges:
Nation-state Cyber Activities
These are attacks carried out by governments or their agents, often to spy, damage infrastructure, or influence political situations. They are usually very sophisticated and have long-term objectives.
Insider Threats
Insider threats arise from within an organization, like employees or contractors. These cyber threats can be accidental or intentional, and they are especially risky because they use legitimate access to get around regular security protections.
Advanced Persistent Threats (APTs)
APTs are complex, stealthy, and secretive attacks that target specific individuals or organizations to steal data or disrupt operations. They often stay hidden for long periods.
Characteristics of APTs
They involve highly targeted, long-term engagements using advanced malware and evasion techniques. Once access is gained, APTs move laterally through networks, establishing footholds in different parts of an organization's digital infrastructure.
