Watering hole incident | United Kingdom 🇬🇧 | Cyber-War: Advanced cyber warfare group hacked a popular UK new site 'Middle East Eye' that often posts content disapproved by GCC / Middle East countries. The site is blocked in many Middle Eastern nations.

The attack vector was based from a known criminal group; 'Candiru' which is declared 📜 criminal by the United States 🇺🇸 and is under sanctions. Candiru is another Cyber-Crime syndicate from Israel 🇮🇱 that operates under Israeli weapons control laws.
