Aliases
Opaserv-E

Type
Win32 worm


Description
W32/Opaserv-C is a variant of W32/Opaserv-A and is a worm that spreads via network shares .

When executed the worm will create a file called brasil . exe or brasil . pif in the Windows folder on the current drive . W32/Opaserv-C then adds one of the following registry entries to run itself when the system starts:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run \Brasil =
C:\WINDOWS\brasil . exe

or

HKLM\Software\Microsoft\Windows\CurrentVersion\Run \Brasil =
C:\WINDOWS\brasil . pif

The worm attempts to copy itself to the Windows folder on networked computers with open shared drives . It then modifies the win . ini file on the remote machine to ensure the copied file will be run on system start . The worm also searches local IP addresses for open C: shares and attempts to copy itself to the Windows folder of the share .

W32/Opaserv-C also attempts to connect to a website that is currently unavailable . This attempted connection is most likely intended as a means of updating the worm executable .

The following three non-viral files may be found in the root folder of infected systems:

put . ini
scrsin . dat
scrsout . dat

What are you using in the way of virus protection, and how up to date is it?

92057 2002-10-23 04:35:00 Hi there from what I can gather it seems looks to be a virus, in fact it is appears to be a variation of the Win32 worm. I suggest you update your virus definitions and run a full system scan, if you do not have an anti-virus program then now would be a good time to get one.

Have a look at the following links on the information I found on brasil.exe, remember viruses can take on many different forms and names so if the file on your machine is not exactly the same as described don't go thinking your safe.
