The report said the groups adapted after tighter airport controls in Lebanon, the collapse of long-standing routes through Syria and the killing of senior Islamic Revolutionary Guard Corps (IRGC) operatives involved in logistics.
Ynet, citing the US Treasury Department, said Iran has transferred roughly $1 billion to Hezbollah since the start of the year, funding that Washington says is used to rebuild the group’s capabilities.
New smuggling channels have increasingly relied on Turkey and Iraq, as well as maritime shipments and cash-based businesses, according to Ynet.
Other methods described in the report include the use of gold transfers, cryptocurrency channels, and shipping components in parts for later assembly in Lebanon.
The report also said Hezbollah has sought to expand local production based on Iranian expertise, reducing dependence on vulnerable cross-border routes.
A US delegation visiting Beirut last week urged Lebanon's leadership to curb financing networks and strengthen oversight of money-exchange agencies.
Analysts quoted by Ynet said they expect Iran to continue supporting Hezbollah’s reconstruction to maintain its political influence within Lebanon’s Shi’ite community.
