researchers have discovered a new version of the Stuxnet malware, known as
"Havex" which was used in a series of cyber attacks against the above
organizations in the energy sector. As you will see in most cases, the
affected sector is the energy sector. The famous Stuxnet worm was designed to
sabotage the Iranian nuclear plants, now, the new version is scheduled to
affect software systems for industrial control SCADA and ICS capabilities
disable devices in hydroelectric dams, as well nuclear power plants and even
disable power grids using these types of devices.
The so-called
Backdoor: W32 / Havex.A and variants of names depending on the antivirus vendor
is a remote access Trojan generic and has recently been detected in a series of
European companies that develop software applications for SCADA and ICS.
Havex is equipped with a new component, whose purpose is to collect
information from the network and connected devices by leveraging the OPC (Open
Platform Communications) standard. OPC is a communication standard that allows
interaction between Windows-based SCADA applications and process control
hardware. The malware scans the local network for devices that respond to
requests from OPC to collect information about industrial control devices and
then sends that information to its command and control server (C & C).
Intelligence on development, has prepared the Havex in a function to collect
information and send it to a server for developers of this worm, can enhance
the Havex more precise functions make efficient and achieve the attack.
One of the issues which are companies that own these types of devices is
still using SCADA with very tight versions of Windows that do not support or
upgrades that may mitigate some of these safety issues and lack of Information
Security Training emphasis on staff adds
another level of threats. What we recommend is that the production line or that
have SCADA network that has the following protections:
1) Where the SCADA
LAN not have Internet access,
2) The teams are
not accessible from the LAN to the users working in the company network.
3) If you must
transfer files, do another VLAN or a segmented network and use services such as
FTP or similar.
4) Do not allow the
use of SCADA pendrive in those devices that support it. Transferring files to
the same should be through a secure channel.
