10 Social Engineering Manipulating individuals to divulge confidential information. Data breaches and financial losses. Employee training and strict information sharing policies.

1. Supply Chain Attacks

Criminals frequently target supply chain vulnerabilities because it allows them to gain entry to larger networks with less security—something seen during the Target brick-and-mortar attack and the Stuxnet worm attacks, both of which targeted small companies that provided components for more advanced systems like factory assembly or nuclear material separation processes.

These attacks take various forms, from malware injections and counterfeit hardware to man-in-the-middle attacks by hackers against SolarWinds and Log4J or physical tampering, as witnessed in a recent breach at CircleCI.

Once attackers gain entry to a supplier’s network, they can spread malware or conduct phishing attacks against companies using that vendor’s software. As a result, organisations should carefully vet all their suppliers to assess the full scope of their attack surface.

2. Critical Infrastructure Attacks

An unsuccessful cyber attack against critical infrastructure systems can have disastrous repercussions, from damage to buildings, vehicles, railways, and railway infrastructure to revenue losses and even loss of life.

The UK National Cyber Security Centre (NCSC) has warned of an ongoing and serious threat to critical assets like our power grid, transport systems, water supply networks, and communications networks.

Many businesses are turning to security monitoring tools in order to quickly detect threats and take immediate action against them. Yet one careless click on a phishing email or other scam could allow hackers to gain access to company systems and gain sensitive data, requiring zero-trust security models with segmentation strategies implemented to mitigate attacks like these. Staff training programmes also play a vital role here, including instructing employees on how to recognise and avoid these types of scams.

3. Cyberwarfare

Cyberwarfare is a form of attack that seeks to replicate the devastating results of conventional war through means such as espionage, sabotage, propaganda, or manipulation, potentially even pre-emptively attacking physical targets.

Stuxnet, one of the best-known examples of cyber warfare, struck Iran’s nuclear reactors in 2010. This malware spread via Universal Serial Bus devices and affected data acquisition and supervisory control systems.

Nation-states and organised crime groups are becoming more sophisticated in their tactics to fight back, including creating malware, hacking into cloud environments and defacing or disabling websites. Cybercriminals have also begun attacking remote workers with attacks such as phishing and distributed denial of service (DDoS). It is therefore essential that businesses implement strong cybersecurity strategies, which must be regularly assessed and updated while simultaneously training employees on what signs to look out for.

4. State-sponsored attacks

Nation-states are using cyber threats for political and economic gains, making the security landscape ever more complicated and demanding multilayered defence systems under comprehensive cybersecurity programs. Businesses must develop multilayered defences against this escalating risk in order to stay protected against nation-state attacks.

Hackers are increasingly targeting public-sector agencies and corporations with attacks such as ransomware. This type of infection prevents users from accessing their files until a payment has been made, creating serious disruption and costs for businesses.

Advanced cyber tools and techniques once restricted solely to nation-state attackers are now widely available on private markets, making more cybercriminals capable of performing attacks on par with nation-states, leading to more frequent and severe attacks against businesses—an upward trend likely continuing into 2024.

5. Ransomware

Hackers will continue to target companies with ransomware attacks that encrypt data before demanding payment to release it. Businesses must implement cyber defences that can detect and respond quickly to such attacks.

In 2021, WannaCry was an unprecedented global cyber attack affecting organisations globally, estimated to cause damages estimated at more than $4 billion. NHS services had to cancel appointments and shut down some services due to this attack; one attack even forced the NHS to pay a ransom of over PS92 million!

Ransomware made up the highest proportion of cyber attacks against businesses (23%), followed by server access and email compromise. Cosmetics retailer Lush recently announced that it was victim to a ransomware attack that affected stores and production facilities worldwide, leading to financial losses and production delays before eventually recovering. Lush’s attackers demanded over $22 million worth of bitcoin as ransom.

6. Cyber Insurance

Cyber insurance has become an essential element of doing business online and offline. It can cover costs associated with recovering compromised data, repairing computer systems, and meeting ransom demands. While insurers generally require businesses to have security policies and procedures in place before providing coverage, it is therefore wise for companies to strengthen their cyber defences before seeking coverage from insurers.

Businesses should educate employees on how to protect themselves against cyber threats, encouraging them to create strong passwords, download software from reliable sources only and avoid suspicious links and emails. Employees should also be trained in recognising and reporting security breaches to protect against potential insider threats that might otherwise go undetected with more people working from home. These steps will ensure businesses stay ahead of the game in 2024.

7. Geopolitical Tensions

Cybercrime is an international threat and geopolitical tensions have only compounded it further. Cybercriminals use it to steal financial data, disrupt supply chains, or attack critical infrastructure using powerful digital tech components.

One recent instance is the escalated conflict between Russia and Ukraine, which impacts trade as well as investors’ confidence in share markets.

Security for Internet of Things devices, sensors, and machines must also be carefully considered, as attackers can gain entry with just a few careless clicks. Other threats to watch out for include no-code malware and plug-and-play kits, as well as fileless attacks that bypass traditional malware traces. Businesses must keep abreast of emerging vulnerabilities as well as emerging attacks to protect themselves against these new risks; additionally, they should train staff members fully on cybercrime awareness training.

8. New Regulations

Security teams today face numerous new obstacles. Internal factors, like workload complexity and a shortage of cybersecurity specialists, are making the task increasingly challenging; external issues, like an evolving threat landscape and complying with data protection regulations, add further burdens.

By 2024, businesses should expect the growing risk of IoT attacks, where third-party vulnerabilities in connected devices (such as refrigerators and thermostats) allow cyber criminals to gain entry to networks and steal sensitive information, along with difficult-to-secure IoT devices lacking basic protection features like multi-factor authentication.

Companies need to prioritise comprehensive defence strategies backed by state-of-the-art information technologies operating under holistic cybersecurity programmes in order to address this threat. Zero-trust models are emerging as a crucial part of this approach as companies attempt to securely enable and control IoT devices for remote workers and customers.

9. Artificial Intelligence

As our world becomes more interconnected, cybercriminals are finding new ways to exploit it for illicit gain. Their attacks can range from theft of personal data and services all the way through to taking over these systems and services altogether.

With AI on the rise, we can expect more sophisticated phishing scams, which are harder to recognise due to a better understanding of human behaviour, and attackers using breached credentials found on the dark web to launch more targeted phishing attempts.

2024 will also witness an increased focus on assurance, with government and industry putting more of an emphasis on security standards and certification regimes to demonstrate AI is safe and trustworthy, providing us with the ability to reap the benefits of emerging information technologies while making sure they respect essential basic human values.

10. Social Engineering

Social engineering attacks use email, text messages, and phone calls to fool victims into disclosing sensitive financial data, such as login credentials. They often use intriguing pretexts or impersonate trusted individuals in order to get them to trust them and then demand either money or information in return.

Examples of social engineering attacks include baiting attacks—leaving a USB stick loaded with malware in public; tailgating attacks, which involve following someone with authorised access into a building; dumpster diving (searching trash for passwords or useful information); and rogue security software (malware that tricks targets into installing their programme).

Establish a risk-aware culture to defend against these types of attacks by training employees on how to recognise suspicious emails and verify urgent requests, ensuring all are familiar with security protocols and receiving regular training.
