A Byte Out of History: How Viruses Shaped Cybersecurity in South Africa (and Beyond)

From harmless-looking email attachments to sophisticated hacking attempts, businesses and individuals alike are vulnerable to a myriad of cyberattacks. The evolution of these threats, from the early days of computer viruses to the complex cybercrime operations of today, has shaped the landscape of cybersecurity.

The Early Days: A Digital Wild West

In the 1970s, when computers were still in their infancy, the first computer viruses emerged. These early threats, such as Creeper and Rabbit, were not malicious but were created as experiments to strengthen cybersecurity in those days. The virus would ‘self-delete’ making it more of a curious digital traveller than a harmful invader. As computers became more interconnected and the internet revolutionised communication, so too did the sophistication of cyber threats.

Creeper (1971)

• Creator: Bob Thomas, a programmer at BBN Technologies.
• Purpose: Creeper was not designed to be harmful. It was created as an experimental program to explore the concept of self-replicating code.

Rabbit (1974)

• Purpose: Rabbit, also known as Wabbit, was an early example of a malicious program designed to demonstrate the impact of excessive resource consumption.
• How It Worked:

Rabbit replicated itself repeatedly, causing the system to slow down and eventually crash due to overuse of system resources like CPU and memory.

The South African Context: A Growing Threat

South Africa, with its rapidly growing digital landscape, is not immune to these threats. In recent years, the country has experienced a surge in cyberattacks, ranging from data breaches to ransomware attacks. These incidents can have devastating consequences, including financial loss, reputational damage, and operational disruption.

Data from Kaspersky reveals that South Africa experienced over 12,000 ransomware attacks in the first half of 2021 alone.

South African-Specific Malware Trends

Ransomware Attacks:

• South African businesses have been targeted by ransomware campaigns like Ryuk, Maze, and DarkSide, particularly in sectors such as finance, healthcare, and logistics.
• Attackers exploit vulnerabilities in local businesses’ systems, encrypting data and demanding payment in cryptocurrency.

Banking Trojans:

• Malware like Emotet, TrickBot, and locally targeted Trojans are prevalent due to South Africa’s advanced banking infrastructure and high internet penetration rates.
• Attackers often target users of South African banks such as FNB, Standard Bank, and Capitec.

SMS and Mobile Scams:

• Mobile malware and SMS phishing (“smishing”) campaigns are tailored to South African users. For example, fake notifications claiming to be from SARS (South African Revenue Service) have been used to trick users into downloading malware.

 

The Evolution of Cyber Threats

As technology advanced, so too did the tactics employed by cybercriminals. The introduction of email and the World Wide Web provided new avenues for the spread of malicious software. Viruses like Melissa and ILOVEYOU wreaked havoc, causing widespread disruption and financial loss.

Melissa Virus (1999)

• Creator: David L. Smith, an American programmer.
• How It Worked:
  • The virus was spread via a Microsoft Word document attached to an email with the subject line, “Important Message from [sender’s name].”
  • When the document was opened, the virus executed a macro that infected the recipient’s machine.
  • It would then access the victim’s Microsoft Outlook address book and send the infected email to the first 50 contacts.
• Impact:
  • It caused email servers to overload due to the sheer volume of infected emails.
  • Estimated damages from the virus ranged between $80 million and $1.2 billion globally.
  • Companies and government systems were forced to shut down their email servers to contain the spread.

ILOVEYOU Virus 2000

• Creators: Two Filipino programmers, Onel de Guzman and Reomel Ramones.
• Purpose: A destructive worm disguised as a love letter. Unlike Melissa, “ILOVEYOU” was highly destructive, targeting files on infected systems.
• How It Worked:
  • Spread via email with the subject line: “ILOVEYOU” and an attachment named “LOVE-LETTER-FOR-YOU.txt.vbs.”
  • When the attachment was opened, it executed a Visual Basic script that:
    • Overwrote and replaced various file types, including images and documents.
    • Copied itself and sent emails to all contacts in the victim’s address book.
  • The worm also attempted to steal user credentials by copying passwords and forwarding them to the virus creators.
• Impact:
  • It infected millions of computers within a few days.
  • Estimated damages exceeded $10 billion globally due to lost productivity and system repairs.
  • Governments and businesses worldwide had to shut down email systems to prevent further spread.

In recent years, we’ve witnessed the rise of advanced persistent threats (APTs), where highly skilled attackers target specific organisations for extended periods. These attacks often involve sophisticated techniques like social engineering, phishing, and exploitation of vulnerabilities.
