BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.
To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.
To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.
(Reuters) — Hundreds of millions of Windows PC users are vulnerable to attacks exploiting the recently uncovered “Freak” security vulnerability, which was initially believed to only threaten mobile devices and Mac computers, Microsoft Corp. warned.
News of the vulnerability surfaced on Tuesday when a group of nine security experts disclosed that ubiquitous Internet encryption technology could make devices running Apple Inc.’s iOS and Mac operating systems, along with Google Inc.’s Android browser vulnerable to cyberattacks.
Microsoft released a security advisory on Thursday warning customers that their PCs were also vulnerable to the “Freak” vulnerability.
The weakness could allow attacks on PCs that connect with Web servers configured to use encryption technology intentionally weakened to comply with U.S. government regulations banning exports of the strongest encryption.
If hackers are successful, they could spy on communications as well as infect PCs with malicious software, the researchers who uncovered the threat said on Tuesday.
The Washington Post on Tuesday reported that whitehouse.gov and fbi.gov were among the sites vulnerable to these attacks, but that the government had secured them.
Microsoft advised system administrators to employ a workaround to disable settings on Windows servers that allow use of the weaker encryption. It said it was investigating the threat and had not yet developed a security update that would automatically protect Windows PC users from the threat.
“Upon completion of this investigation, Microsoft will take the appropriate action to help protect customers,” it said. The Redmond, Washington-based company said that might include providing a security update in a monthly software release or putting out an unscheduled update.
Chris Wysopal, chief technology officer with security software maker Veracode, noted that it was not possible to change that setting on Windows Server 2003, a version of Microsoft’s operating system for servers that is more than a decade old.
Windows Server 2003 “remains vulnerable,” Mr. Wysopal said. “There is nothing you can do if you are running a Web server on this OS.”
Apple said it had developed a software update to address the vulnerability, which would be pushed out to customers next week.
Google said it had also developed a patch, which it provided to partners that make and distribute Android devices.
“Freak” stands for “Factoring RSA-EXPORT Keys.”
(Reuters) — The U.S. National Security Agency has figured out how to hide spying software deep within hard drives made by Western Digital, Seagate, Toshiba and other top manufacturers, giving the agency the means to eavesdrop on the majority of the world's computers, according to cyber researchers and former operatives.
