Pakistan, Indonesia lead in malware assaults: Microsoft report

SAN FRANCISCO — Pakistan, Indonesia, the Palestinian territories, Bangladesh and Nepal attract the highest rates of attempted malware attacks, according to Microsoft Corp.

Countries that attracted the fewest include Japan, Finland, Norway and Sweden, Microsoft said in a new study, based on sensors in systems running Microsoft anti-malware software.

“We look at north of 10 million attacks on identities every day,” said Microsoft manager Alex Weinert, although attacks do not always succeed.

About half of all attacks originate in Asia and one-fifth in Latin America.

Millions occur each year when the attacker has valid credentials, Microsoft said, meaning the attacker knows a user’s login and password.

A technology known as machine learning can often detect those attacks by looking for data points such as whether the location of the user is familiar.

On average, 240 days elapse between a security breach in a computer system and detection of that breach, said Tim Rains, director of security at Microsoft.

The study, Microsoft Security Intelligence report, comes out Thursday.

KATHMANDU — In an incredible development that could possibly go a long way in medical practices, scientists in California are working on a way to reduce organ transplants and rejections: Growing embryos in sheep and pigs containing human patients’ cells.

In a transplant breakthrough, scientists at the University of California said they have achieved sheep embryos in which around one in every 10,000 cells was human, according to UPI report.

The researchers presented preliminary findings Saturday at the American Association for the Advancement of Science’s annual meeting in Austin, Texas.

The new finding paves way for genetically tailoring the organs to be compatible with the immune system of the patient receiving them, thus removing the possibility of rejection, the report said.

The hybrid embryos contain both human and sheep cells and were created in an early step toward growing human organs in farm animals before transplanting them into patients.

Last year, the same researchers introduced human stem cells into early pig embryos, producing embryos with about one in every 100,000 cells being human.

The experiment began with Hiro Nakauchi, from the University of Tokyo, who grew a mouse with a rat pancreas and a rat with a mouse pancreas.

When cells from the rat-grown mouse pancreas were transplanted into a diabetic mouse, they made enough insulin to cure the condition without being rejected.

Mice and rats are different types of rodents with the former having thin slightly hairy tails, while rats have thicker hairless scaly tails.

“The next step was to move into large animals,” Nakauchi said. Since this was prohibited in Japan, he moved to the Stanford University in the US.

Nakauchi’s rodent work has demonstrated that you can “grow organs in a different species and cure a disease without [suppressing the immune system],” added co-researcher Pablo Ross, Professor at from the University of California, Davis.

“We are working together to translate the technology into humans, to solve the terrible shortage of organs for transplantation. In the US, 20 people die every day because they cannot get the organs they need,” Ross explained.
