In other words, the source code isn’t human-readable. This was because the malware used nested run-only AppleScript files to retrieve its malicious code across different stages.ĪppleScripts arrive in a compiled state. Incidentally, security researchers weren’t able to retrieve the malware’s entire code when they had sensed its activities back in 2018.

Named OSAMiner, the malware has been distributed in the wild since at least 2015 disguised in pirated (cracked) games and software such as League of Legends and Microsoft Office for Mac. From what data we have it appears to be mostly targeted at Chinese/Asia-Pacific communities.” “OSAMiner has been active for a long time and has evolved in recent months. The distribution is active since at least 2015, indicated security firm SentinelOne in a report published this week. SentinelOne's analyses the OSAMiner macOS cryptocurrency-mining malware that, thanks to its use of run-only AppleScripts, stayed under the radar for a long time also open sources the AEVT decompiler tool /TqIAl8QcmrĪccording to security researchers, the OSAMiner malware was distributed inside pirated (cracked) games and software such as League of Legends and Microsoft Office for Mac. The creators of the malware used processes that were specifically designed to evade detection and analysis by security researchers. As they are slowly buried by sedimentation, the damaged leaf sheaths form stiff fibres that intertwine into a ball, collecting plastic in the process.The OSAMiner hijacked the hardware resources of infected users to mine cryptocurrency. The oval orbs - the shape of a rugby ball - form from the base of leaves that have been shredded by the action of ocean currents but remain attached to stems, called rhizomes. Using estimates of seagrass fibre production in the Mediterranean, the researchers worked up an estimate of how much plastic might be filtered in the entire basin. Only 17% of the tighter bundled seagrass fibre known as Neptune balls contained plastic, but at a much higher density - nearly 1,500 pieces per kilogram of seaball. There was plastic debris in half of the loose seagrass leaf samples, up to 600 bits per kilogram of leaves. In 20, they counted the number of plastic particles found in seaballs that had washed up on four beaches in Mallorca, Spain, which has large seagrass meadows offshore. To better understand the plastic bundling capabilities of seagrass, Sanchez-Vidal and her team studied a species found only in the Mediterranean sea, Posidonia oceanica.

This clean-up "represents a continuous purge of plastic debris out of the sea," she added. "We show that plastic debris in the seafloor can be trapped in seagrass remains, eventually leaving the marine environment through beaching," lead author Anna Sanchez-Vidal, a marine biologist at the University of Barcelona, told AFP. The Guardian reports: With no help from humans, the swaying plants - anchored to shallow seabeds - may collect nearly 900 million plastic items in the Mediterranean alone every year, a study reported in the journal Scientific Reports said. Underwater seagrass in coastal areas appear to trap plastic pollution in natural bundles of fiber known as "Neptune balls," researchers have found.
