'Morto' targets weak passwords, usernames and spreads via the Remote Desktop Protocol.
A retro worm attack is underway that takes the unusual spin of employing the Remote Desktop Protocol (RDP) in Windows' remote desktop connection feature as its attack vector.
Researchers from Microsoft, F-Secure, eEye Digital Security, and other organizations say the so-called Morto worm infects Windows workstations and Windows servers. It spreads by uploading a Windows DLL file to a targeted machine. The worm looks for weak administrator passwords in Remote Desktop on an organization's network--everything from "12345" to "admin" and "password."
Researchers say the attack could be used for various purposes, including distributed denial-of-service (DDoS) attacks against targeted organizations. "The remote control feature allows bot-like control of the infected machines and they can be used for basically any purpose," says Mikko Hypponen, chief research officer of F-Secure Lab.
Microsoft's Malware Protection Center (MMPC), which sounded the alarm about the worm over the weekend, on Friday added detection for Worm:Win32/Morto.A. The relative number of infections isn't as high as with other malware families, but the worm generates "noticeable" amounts of traffic, according to Microsoft.
As of Saturday, there were only a few thousand computers infected with Morto, according to Microsoft's data. That's in contrast to nearly 30,000 infected with the Sality family of malware, and more than 10,000 with IRCbot malware, according to Microsoft.
"Based on telemetry through the remainder of Sunday, August 28, we are continuing to see low detections in comparison to established malware families as mentioned in the MMPC blog," says Pete Voss, senior response communication manager for Microsoft Trustworthy Computing. "It's important to remember that this malware does not exploit a vulnerability in Remote Desktop Protocol, but instead relies on weak passwords ... We encourage people to use strong passwords to help protect their systems."

The cybersecurity profession struggles to retain women (figures range from 10 to 20 percent). It's particularly worrisome for an industry with a rapidly growing number of vacant positions.
So why does the shortage of women continue to be worse in security than in other IT sectors? How can men in infosec be better allies for women; and how can women be better allies for one another? What is the industry doing to fix the problem -- what's working, and what isn't?
Is this really a problem at all? Are the low numbers simply an indication that women do not want to be in cybersecurity, and is it possible that more women will never want to be in cybersecurity? How many women would we need to see in the industry to declare success?
