Fishing activities are putting ecologically important shark hotspots worldwide in danger, researchers have warned.

“Currently, little to no protection exists for sharks in the high seas. It’s clear from our study that immediate conservation action is needed to prevent further declines of open-ocean sharks,” said study co-author Neil Hammerschlag from the University of Miami in the US.

“These findings are concerning because as top predators, sharks help maintain healthy ocean ecosystems,” said Hammerschlag.

For the study published in the journal Nature, the international team of over 150 scientists from 26 countries combined movement data from nearly 2,000 sharks tracked with satellite tags.

Using this tracking information, researchers identified areas of the ocean that were important for multiple species, shark “hot spots,” that were located in ocean frontal zones, boundaries in the sea between different water masses that are highly productive and food-rich.

Researchers then calculated how much shark hotspots overlapped with global longline fishing vessels — the type of fishing gear that catches most open-ocean sharks.

The study found that 24 per cent of the space used by sharks in an average month falls under the footprint of longline fishing.

For commercially exploited sharks such as blue and shortfin makos sharks in the North Atlantic, the overlap was much higher, with on average 76 per cent and 62 per cent of their space use, respectively, overlapping with longlines each month.

Even internationally protected species, such as great whites, had over 50 per cent overlap with longline fleets, said the study.

“Our results show major high seas fishing activities are currently centred on ecologically important shark hotspots worldwide,” said Professor David Sims, who led the study as part of the Global Shark Movement Project based at the Marine Biological Association Laboratory in Plymouth, UK. (IANS)

Security researchers have discovered a bunch of vulnerabilities affecting 4G hotspots from Chinese handset maker ZTE that could allow a potential hacker to redirect traffic from the hotspot to other malicious websites.

Discovered by a Pen Test Partners researcher, who goes by the name of “Dave Null”, the security flaws in the hotspot devices were disclosed at Defcon — an annual hacking conference held in Las Vegas on Saturday, CNET reported.

According to Null, in order to exploit the vulnerabilities, an attacker only needed the victim to visit a malicious website using one of ZTE’s hotspots.

Once the attacker had the password to the hotspot, there were plenty of options for further hacks.

The hacker could start logging a person’s web activity, use the hotspot as a way to attack devices connected to it and redirect web traffic to more malicious websites, the report said.

Null claimed that the vulnerabilities are likely to apply to more ZTE products in the “MF” line because many of the devices share the same code, the report noted. (IANS)
