Mac OS X’s reputation for security was tarnished Thursday when a team of researchers from Independent Security Evaluators (ISE) managed to hack a MacBook Air in two minutes using a zero-day vulnerability in Apple’s Safari 3.1 Web browser.

Telefon bimbit tidak sebabkan kanser otak

LONDON 6 Feb. _ Sekumpulan saintis dari Jepun mendapati penggunaan telefon bimbit tidak menyumbang kepada peningkatan risiko jangkitan kanser otak seperti yang didakwa sebelum ini.

Saintis dari Universiti Perubatan Wanita Tokyo itu menjalankan kajian penggunaan telefon bimbit di kalangan 322 pesakit kanser dan 683 pengguna yang sihat.

Hasil kajian yang diterbitkan dalam Jurnal Kanser Britain itu mendapati, penggunaan telefon bimbit secara kerap tidak menunjukkan tanda-tanda jangkitan kanser otak.

Selain itu, kumpulan penyelidik turut menjalankan kajian mengenai sinar radiasi daripada pelbagai jenis telefon bimbit bagi mengenal pasti kemungkinan penggunaannya memberi kesan kepada bahagian otak yang berbeza.

“Dengan menggunakan kaedah dan teknik terbaru yang kami bangunkan, didapati tiada kaitan antara penggunaan telefon bimbit dengan kanser, sekali gus membuktikan telefon bimbit tidak menyebabkan kanser otak,” kata ketua kumpulan berkenaan, Naohito Yamaguchi. - Reuters

SAN FRANCISCO — Hackers have launched a rare and troubling attack on Apple Inc.’s computers.

Apple on Thursday confirmed reports of pornography Web sites where hidden software, once downloaded, could take control of an Apple computer. Apple did not immediately respond to claims that it is the first instance of a Trojan horse attack on Apple’s Macintosh platform.

“We’ve been made aware that a small number of Web sites attempt to trick Mac OS X users to install malicious software on their Macs,” said Apple spokeswoman Lynn Fox. “Apple has a great track record for keeping Mac OS X users secure, and as always, we encourage people to install software only from trusted sources.”

Most of us face the prospect of upgrading our operating systems with a mixture of excitement and dread. True, a new OS brings cool new ways to work. But that doesn’t change the fact that when you install a major version of OS X you’re essentially gutting your Mac and replacing its virtual insides.

Luckily, Apple’s improved the upgrade experience with each new cat, making the process much less daunting. But despite the Installer’s useful guidance, there are things it doesn’t tell you, and places where its help falls short. With that in mind, here’s my guide to making the upgrade process as trouble-free as possible.
What You Need

Before you get started, the two most important things you need are a compatible Mac and a complete backup of all your data. Leopard requires a Mac with an Intel or PowerPC G4 or G5 processor; a DVD drive; built-in FireWire; at least 512MB RAM; and at least 7GB of free hard-disk space. (I recommend at least 1GB RAM and 10 to 15GB of free disk space.)

A notorious Russian hacker gang is responsible for ongoing attacks using malicious PDF documents, a researcher said Wednesday.

Users can thank the Russian Business Network (RBN), a well-known collective of cybercriminals, for the malware-armed PDF attachments that began appearing in in-boxes Tuesday, said Ken Dunham, director of response for iSight Partners Inc. If the rigged PDFs succeed in infecting the target Windows system, the attack code installs a pair of rootkit files that “sniff and steal financial and other valuable data,” said Dunham via e-mail.

The rogue PDF documents are attached to spammed e-mail and arrive with filenames such as BILL.pdf, YOUR_BILL.pdf, INVOICE.pdf or STATEMET.pdt, said Symantec Corp. in a separate advisory Tuesday. They exploit the “mailto:” protocol vulnerability disclosed more than a month ago by U.K.-based researcher Petko Petkov.
