Microsoft IIS web server under attack from hackers

Microsoft has updated a security advisory concerning vulnerabilities in its Internet Information Services (IIS) web server, confirming that “limited” attacks were using publicly available exploit code.

 

The attacks are targeting flaws in the FTP service in Microsoft IIS 5.0 and could allow remote execution attacks or denial of service (DoS) attacks in IIS 5.0 as well as 5.1, 6.0 or 7.0.

 

Microsoft said it was aware that detailed exploit code had been published for the vulnerabilities, and was “actively monitoring this situation to keep customers informed and to provide customer guidance as necessary.”

 

Microsoft said in the advisory: “These vulnerabilities were not responsibly disclosed to Microsoft and may put computer users at risk.”

 

Tomorrow’s Patch Tuesday has come too soon to fix the IIS vulnerabilities in question, but Microsoft said it would take the appropriate action, which could mean a security update released for a future Patch Tuesday or an out-of-cycle security update.

Twitter Has Been Taken Offline by an Ongoing Denial Of Service Attack.

Twitter has been knocked offline by a denial of service (DoS) attack.

 

The popular social networking site has been offline for more than an hour, with a message on its status page saying: “We are defending against a denial-of-service attack.”

 

On the Twitter blog, co-founder Biz Stone wrote: “On this otherwise happy Thursday morning, Twitter is the target of a denial of service attack.”

 

“Attacks such as this are malicious efforts orchestrated to disrupt and make unavailable services such as online banks, credit card payment gateways, and in this case, Twitter for intended customers or users,” he said.

 

Twitter has promised an update soon. The site has suffered outages before, but normally because of sudden upswings in traffic.
