More Information
W32/Rbot-BEC is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-BEC spreads:
- to computers infected with the W32/Sasser worm
- to other network computers by exploiting common buffer overflow
vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WebDav (MS03-007), and ASN.1 (MS04-007)
- by copying itself to network shares and Microsoft SQL servers protected by weak passwords
W32/Rbot-BEC runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/Rbot-BEC copies itself to <System>\TNTSETP.exe.
The following registry entries are created to run TNTSETP.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
PHIME2004A
TNTSETP.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
PHIME2004A
TNTSETP.exe
The following registry entry is set:
HKCU\Software\Microsoft\OLE
PHIME2004A
TNTSETP.exe
