ATHENS, April 21 (Reuters) - Fraudulent messages promising safe passage through the Strait of Hormuz in exchange for cryptocurrency have been sent to some shipping companies whose vessels are stranded west of the waterway, Greek maritime risk management firm MARISKS has warned.
The U.S. has maintained its blockade of Iranian ports, while Iran has lifted and then re-imposed its blockade of the Strait of
Hormuz, through which roughly a fifth of the world's oil and liquefied natural gas passed before
war broke out in the Middle East.
