U. S. Coast Guard personnel and FBI agents boarded two Texas‑bound energy tankers last month after cyberattacks hit the vessels while they were underway, according to U. S. officials. One of the ships was the VL Prosperity, a 1,093‑foot Liberian‑flagged crude oil supertanker headed to Galveston, Texas.
