in waters off western
Malaysia, January 2006. The
International Maritime Bureau (IMB) reports worldwide pirate attacks fell for the third year in a row in 2006. Attacks on ships at sea in 2006 fell to 239 vessels, down from 276 in 2005. That same trend echoed in the Strait of Malacca where attacks dropped from 79 in 2005 to 50 in 2006. Nonetheless, in 2004, the region accounted for 40% of piracy worldwide. The IMB reported in October 2007 that Indonesia continued to be the world's most pirate-struck region with 37 attacks since January 2007, though that was an improvement from the same nine-month period in 2006. The
September 11 attacks also heightened the perceived threat of terrorism-related piracy, but
US Maritime Administration (MARAD) experts distinguish terrorism from piracy, and piracy from shore gangs who rob ships in port. Some observers argue that there is no single problem of violence at sea, but rather a collection of problems, and that different kinds of violence require different defences. Technology is being used to combat pirates, in addition to air and sea patrols. For instance, the IMB's 2006 annual report notes that since July 2004 vessels of 500
gross tons or more must have security alert systems on board. Security systems include near-real-time ship location devices. Furthermore, the Federation of
ASEAN Shipowners' Associations has launched a database system to provide updated information on location, types of attacks, and outcomes. The system, called the "Information Sharing Centre (ISC)", is part of a 14-nation pact to combat pirates. According to the
Singapore Transport Ministry's Permanent Secretary, "Piracy is a transnational problem and this is the first time an international body has been set up to deal solely with the problem of piracy in Asia." Violent, armed pirates robbing crews at sea create attention-getting headlines, but the direct economic impact of robbery at sea is small relative to the volume of global trade in the area. Typical pirate booty is limited to ship's stores, engine parts, and crew members' cash and personal property. Piracy also has indirect costs, including increased security measures and spikes in shipping insurance premiums. For instance,
Lloyd's of London declared the strait a high war-risk area for insurance purposes, underscoring the Strait of Malacca's outlaw reputation in recent years. The action added a premium of 1% of cargo value, "infuriating shipping lines", according to news reports. The declaration of the sea lane as a high war-risk area referenced the waterway's "war, strikes, terrorism, and related perils". Company officials, however, lifted the advisory in 2006, after Singapore and Indonesia launched their sea and air patrols. Pirate attacks have not stopped the 50,000 ships that annually transit the narrow passage. Forty percent of the world's trade passes through it and it has become the most important route of transport for oil from the Middle East to markets in East Asia. According to the IMB, the majority of modern pirates in the region are of Indonesian origin. Of the countries in the region, Indonesia's navy is least equipped to combat piracy. Instances of modern piracy typically fall into one of three categories: those looking for easy profit, those working with or belonging to
organised crime syndicates, and those associated with terrorist or
secessionist groups with political motivations. Pirates looking only for easy profit are usually criminals of opportunity. They search for easy targets, robbing ships and their crews of money and valuables. Those belonging to organised criminal syndicates attack with more sophistication and planning. Their operations, which require skill, co-ordination, and funding, aim to steal large cargoes or to kidnap ships' crews for
ransom. The kind of piracy related to terrorism operates similarly, but differs in that it seeks funding to continue terrorist activities or to make political statements. In 2014, a new piracy strategy of specifically targeting oil and diesel tankers emerged. This caused concern about the revival of piracy in the Straits of Malacca. In 2024,
ReCAAP reported targeted stealing of engine spares by pirates as unique to the
Singapore and Malacca Straits, indicating the possibility of a
black market. The threat of piracy in the Strait of Malacca has also contributed to China's broader security concerns, as reliance on the strait for energy imports has made it a focal point of what Chinese leaders have called the "
Malacca dilemma," a strategic vulnerability tied to both piracy and the risk of foreign interdiction during conflict. According to ReCAAP, there were 107 incidents of piracy in the Straits of Malacca in 2024, representing a 6% increase from 2023. Piracy and robbery surged in the first half of 2025, with 80 incidents as opposed to 21 in 2024.
Multi-national collaboration In 2004, the four countries in the region, Indonesia, Thailand, Malaysia, and Singapore, increased efforts to patrol the strait in an attempt to curb piracy. While Singapore wants international support in this effort, Indonesia and Malaysia are opposed to foreign intervention. It remains to be seen whether the three countries will be able to stamp out piracy. The problem is especially acute in Indonesia. There were 325 reported pirate attacks worldwide in 2004; nine occurred in Malaysian waters, twenty in Thai waters, eight in Singaporean waters, and the highest at 93 in Indonesian waters. the
Indian Navy and
Indian Coast Guard finally agreed to join the multinational piracy patrol in the Strait of Malacca in 2006. India is also building a
UAV-patrol base in the
Andaman and Nicobar Islands to monitor the
Andaman Sea adjacent to the Strait of Malacca. Due to co-operation between these countries, and to some extent with Thailand, piracy in the region has almost been eradicated, with only two attempts in 2008. But according to piracy expert
Catherine Zara Raymond, On 21 April 2011, the Chief of
Malaysian Defence Forces Jeneral Tan Sri Dato’ Sri Azizan Ariffin said the Strait of Malacca last year achieved a "close-to-zero incident level" due to the collaboration among the countries in the Malacca Straits Patrol (MSP) — Malaysia, Singapore, Indonesia, and Thailand. ==Prominent pirates in the Strait of Malacca==
