These are the South African companies most at risk of being hacked

These are the South African companies most at risk of being hacked

South African companies are some of the most vulnerable in the world when it comes to potential cyber attacks, according to the latest Cyber Exposure Index, released by Cyber Intelligence Research Group and Kinkayo.

The index is based on data collected from publicly available sources in the dark web, deep web and data breaches.

A company’s risk is then calculated using different variables including identified clear text passwords, hashed passwords, phishing target lists, hacker group target lists, source code, email messages and internal documents.

From that data, signs of sensitive disclosure, exposed credentials and hacker group activity against a company are identified.

Company ranking is relative to global scoring that is populated from 11 stock exchanges worldwide as well as fortune 500 companies. Each company gets an exposure score based on the variables and risks they represent. Exposure scores are then distributed to 5 categories statistically.

Level 5 are the top 1% or the most exposed companies. Following this, Level 4 contains the next 24% most exposed companies and so on.

At level 0 there is no exposure in the past 12 months.

  • Category 5: Companies in this category are ranked in the 1% of companies with the most exposure.
  • Category 4: Companies in this category are ranked are ranked in the 25% of companies with the most exposure.
  • Category 3: Companies in this category are ranked in the 50% of companies with the above average exposure.
  • Category 2: Companies in this category are ranked in the 50% of companies with the below average exposure.
  • Category 1: Companies in this category are ranked in the 25% of companies with the least exposure.
  • Category 0: Companies in this category have no visible exposure in the past 12 months.

South African companies

According to the report, South Africa has one of the highest average ratings in the world at 1.9 (out of 5) – behind only France and Sweden.

The report found that Nedbank was the company most in danger of being exposed (category 4). This was followed by ArcelorMittal South Africa, Sasol Inzalo Public Asset-B, Sasol Ltd, and Telkom SA to round up the top five.

Other notable tech companies in the category 4 ranking include MTN and EOH – while Vodacom, Naspers and Blue Label Telecoms were all given a category 3 rating.
