Japan working on powerful cyber weapon, knows best defense is a good offense

The Japanese government has been (relatively) quietly churning away on an advanced new cyber weapon. In the post Stuxnet age it's no surprise that a government would be working on powerful new tools to defend its digital borders, but this particular virus (developed with help from Fujitsu) is raising eyebrows with some over how it accomplishes its goals. Essentially, when it detects an intruding piece of malware, the program follows the virtual trail left behind back to the attack's source -- disabling every machine it encounters along the way. The goal, obviously, is to stop the spread of a malicious piece of code by finding and shutting down, not just the source, but all middleman PCs that are also now potential hosts. In some admitedly extreme scenarios this weapon could potentially spiral out of control, taking out far more computers than intended. Nightmarish hellscapes dominated by computers run amok aside, its definitely interesting and we understand how it might cause some concern. Check out the source for a few more details.

Microsoft Releases Huge Update Patch 10/13 For 49 Bugs

Microsoft has released its largest-ever bundle of patches, pushing out 16 updates that fix a total of 49 individual vulnerabilities. The patches include updates for six critical vulnerabilities, most notably a huge fix for some remote code-execution bugs in various versions of Internet Explorer.

The Internet Explorer update addresses a total of 10 vulnerabilities across several different versions of IE on operating systems from XP up through Windows 7. A pair of uninitialized memory corruption vulnerabilities in IE 6 up through IE 8 are deemed the mst dangerous by Microsoft, with both drawing the critical rating. Only one of them is rated critical on IE 8, however.

“Looking at the number and type of updates this month, we have a fairly standard number of bulletins affecting products like Windows and Office. This month we also have a few bulletins originating from product groups that we don’t see on a regular basis. For example, SharePoint, the Microsoft Foundation Class (MFC) Library (which is an application framework for programming in Windows), and the .NET Framework. It’s worth noting that only six of the 49 total vulnerabilities being addressed have a critical rating. Further, three of the bulletins account for 34 of the total vulnerabilities,” Microsoft said.

In addition to the IE bugs, there also is a critical flaw in the .Net Framework running on Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and Windows 7. The bug enables a remote attacker to run arbitrary code on a vulnerable machine.

One of the other bugs that Microsoft patched is MS010-073, one of the vulnerabilities used in the Stuxnet attack.

“It’s great to see Microsoft release MS010-073, patching multiple vulnerabilities in win32k.sys on multiple operating systems. It’s interesting that it’s rated only ‘Important’, because CVE-2010-2743 is being exploited in the wild. Our research team found and reported the Win32k Keyboard Layout Vulnerability to Microsoft levaquin coupon when we discovered it exploited by Stuxnet early on in our research. It was one of the 0days used by Stuxnet to execute shellcode at system level privileges by abusing the NtUserSendInput function,” said Kurt Baumgartner, a senior security researcher at Kaspersky Lab.

For years many people thought that if you had a Mac or a Linux based PC, that you were safe from most, if not all malicious activity on the internet. Now we are learning that isn’t quite true anymore. Here is what IBM’s report had to say:
