Win32/SillyAutorun Family
by Marianna Schmudlach / March 3, 2009 11:56 PM PST

Type : Worm

Category : Win32

Also known as: Worm.Win32.AutoRun (Kaspersky), Worm:Win32/Autorun (MS OneCare), WORM_AUTORUN (Trend), W32/Autorun.worm (McAfee), W32.SillyDC (Symantec), Mal/SillyFDC (Sophos)


Description

Win32/SillyAutorun is a large family of worms that spread via removable and physical drives.

Once executed, SillyAutorun generally copies itself to a variable location on the compromised system (often the %System% or %Windows% directory) and creates registry entries to run itself each time Windows starts. For example, Win32/SillyAutorun.AHQ copies itself to the %System% folder as "CSRCS.EXE" and adds the following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\csrcs = "%System%\csrcs.exe"
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell = "Explorer.exe csrcs.exe"
HKCU\Software\Microsoft\Windows\ShellNoRoam\MUICache\%System%\csrcs.exe = ""

Five per cent of all company PCs infected with bots
by Marianna Schmudlach / March 3, 2009 11:58 PM PST

4 March 2009

Damballa, a security services provider, has published a studyPDF that says three to five per cent of all company systems are infected with bots. According to Damballa, anti-virus software frequently affords no protection against infection because the response of anti-malware lags behind the introduction of new threats, so the detection rate when new bots appear is only around 53 per cent. Over time the rate then improves to 85 per cent as anti-virus programs add new signatures.

The study says that on average 54 days go by before a bot is detected. Even after 180 days, 15 per cent of infections remain undiscovered. Companies are reported to be particularly vulnerable to the botnet problem due to several factors, including poor detection. One Damballa client reportedly observes one hundred new bot infections on their systems every day. Damballa says anti-virus software must be supplemented by monitoring network traffic, in order to detect communications between bots and their command-and-control server.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
