So why do we need digital literacy, awareness, and a guard? Because the importance of understanding the risks and responsibilities associated with our online activities cannot be overstated, as cyber threats take different forms—each presenting unique dangers. Every day, or every hour, somewhere in this world, some individuals are being targeted and exploited through cybercrime. The threat of this looms large in the digital realm, affecting individuals, businesses, and governments alike. Consequently, the following examples represent some of the most common cyberattacks:

  1. Malware attack: A malware attack or malicious software is a type of cyberattack where it infiltrates a computer system or network with the intent to exploit data, damage devices, or disrupt operations and communication. Malware can disguise itself in many forms, including viruses (spread through infected files), worms (self-replication), Trojans (deceptive software), ransomware (encrypts data), and spyware (steals information), each designed to carry out specific malicious activities.

Case: WannaCry Attack

In May 2017, a ransomware named "WannaCry" spread globally, encrypting data and demanding ransom payments in Bitcoin. This malware targeted computers running Windows and threatened to release data if the ransom was not paid. It affected over 200,000 computers across 150 countries, including individuals, government agencies, and companies. One example of this is the case of the National Health Service (NHS) in England, which encountered significant disruptions.

The ambulance service, for instance, experienced disruptions to their operations, including the disabling of ambulance handover processes and screens, as well as the unavailability of the Patient Transport Service booking portal. Tertiary centers also faced challenges, such as the inability to transfer CT/MR scans and access Chemo Care, resulting in the inability to transfer chemotherapy orders to providers. Similarly, primary care IT providers closed network access, leading to the failure of automated blood results transfer and restricted access for certain general practitioners to their caseloads. These incidents underscore the critical importance of robust cybersecurity measures in healthcare systems to mitigate the impact of cyber threats on patient care and operational efficiency.

A curtain to this malware was discovered by British cybersecurity expert Marcus Hutchins where a "kill switch" was found within the ransomware code. This mechanism relied on a specific domain name; if registered and accessible, it would halt the malware's encryption routine, effectively stopping its spread. Hutchins registered the domain upon noticing this behavior, leading to an immediate slowdown in the ransomware's propagation. By activating this kill switch, Hutchins unintentionally mitigated the impact of the WannaCry ransomware attack, preventing further infections globally.

  1. Phishing: denotes a form of cyberattack wherein malicious actors employ deceptive emails or messages to lure recipients into interacting with fraudulent websites. These websites are typically laden with malware, including ransomware, capable of compromising organizational systems. Alternatively, they may be crafted to deceive users into divulging confidential credentials or executing unauthorized financial transactions.

 

Case: 2018 FIFA World Cup Phishing

The Fédération Internationale de Football Association (FIFA) hosts the world's largest football competition every four years, captivating the attention of individuals worldwide, not just football enthusiasts. Deciding who stands atop the world, conquering the grass field arguably captures the attention of all individuals. With this attention, the event also presented opportunities for some to exploit.

Example screenshots of phishing emails during the 2018 World Cup

During the 2018 FIFA World Cup, cybercriminals took advantage of the global excitement surrounding the event by orchestrating a phishing scam. Targeting football fans and individuals seeking accommodation in Russia, the scam involved deceptive messages claiming recipients had won tickets to the World Cup through a lottery or offering rental properties at unusually low prices. These messages prompted recipients to enter personal information or credit card details to claim their prize or secure accommodation. However, there was no legitimate lottery or rental offer; instead, the cybercriminals aimed to steal sensitive information for fraudulent purposes.

From this incident, it's important to note that in many cases of cybercrime, especially phishing scams, victims may not receive direct reimbursement for their losses. Victims of phishing scams often suffer financial losses due to unauthorized charges, identity theft, or other fraudulent activities resulting from the disclosure of their personal information. In some cases, individuals may be able to recoup their losses through insurance policies or by working with their financial institutions to dispute unauthorized charges. Additionally, law enforcement agencies may investigate such scams and prosecute perpetrators, although the chances of recovering lost funds may vary depending on the circumstances of the case and the jurisdiction involved.

To combat such scams, organizations like FIFA and law enforcement agencies issued warnings and educational materials to raise awareness among the public about the risks of phishing. While some individuals may have fallen victim to these scams, increased awareness and vigilance helped mitigate the impact, emphasizing the importance of cybersecurity hygiene in safeguarding against such threats.

  1. Password Attack: A frequently utilized cyberattack, often directed at the general public and ordinary individuals. These malicious tactics encompass a range of methods, including brute force (repeatedly trying different password combinations), keylogging (capturing keystrokes to obtain passwords), dictionary attacks (using commonly used passwords or words), and credential stuffing (employing stolen username/password combinations). These techniques are employed to exploit weak or compromised passwords, granting unauthorized access to systems or accounts.

 

Case: Yahoo Data Breaches

In late 2014, a seismic breach shook the foundations of cybersecurity, thrusting a digital behemoth, Yahoo, into the epicenter of a global crisis. Initially undisclosed until 2016, this breach saw over 500 million user accounts compromised, unleashing a deluge of sensitive information into the hands of cybercriminals. The attackers, through sophisticated manipulation of web cookies, infiltrated Yahoo's fortified defenses, gaining access to a treasure trove of personal data including account names, email addresses, phone numbers, birth dates, and even hashed passwords.

It was security experts who uncovered a stark reality: while the majority of Yahoo's passwords were safeguarded by the robust bcrypt (secure password hashing algorithm) hashing algorithm, a subset remained vulnerable, shackled to the outdated MD5 algorithm. This critical vulnerability underscored the urgent need for fortified encryption protocols, as cyber threats evolved at an unprecedented pace.

From this global crisis, Yahoo data breaches served as a poignant wake-up call, prompting a global reckoning with the vulnerabilities inherent in the digital landscape and the imperative for proactive cybersecurity measures to safeguard against future breaches.
