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.
