Virus infects killer US air drone fleet

October 11th, 2011

Computers controlling the US Air Force’s killer Predator and Reaper drones have been infected by a key-logging virus, according to a mole who spoke to Wired. And the malware is not going away despite serious efforts to nuke it.

The remote-controlled bomb planes have flown in missions since the discovery of the virus two weeks ago.

Consoles at the Creech Air Force Base in Nevada have been infected by the virus – the ‘cockpit’ from which the majority of the US Army’s unmanned Predator and Reaper drones are directed. Each aircraft is controlled by a pilot in the Nevada station using computers, video feeds and a joystick. Drone missions are carried out in places including Pakistan, Yemen and Afghanistan, and have killed an estimated 2,000 people so far.

The virus doesn’t affect the functioning of the aircraft, but it is monitoring and saving every keystroke the pilots make. It is believed that the malware won’t be able to transmit the information it collects beyond the classified military network hosting the equipment; the network is insulated from the public internet. But it has proved very hard to eradicate from the system.

Computer security technicians have disinfected all the internal hard drives on the operator consoles, but this does not seem to have rid the network of the problem.

“We keep wiping it off, and it keeps coming back,” a source familiar with the network infection told Wired. “We think it’s benign. But we just don’t know.”

It is thought that the virus was introduced to the system via a hard drive or a disk that had picked up the bug elsewhere.

Sky News also highlighted the risk of introducing malicious electronics or software into military hardware if chips are brought in from foreign sources.

“Sky News Online has previously seen US defence documents warning of the dangers for military systems constructed with non-military, commercially-bought computer chips sourced from Asia,” they write.

Virus infects program that controls U.S. drones

October 11th, 2011

They’ve become a linchpin of projecting U.S. military power into war zones around the world. But now those same unmanned aerial vehicles have been infected by a computer virus, according to a U.S defense official.

The drones are still flying missions in places like Afghanistan and Iraq, where as many as 150 of them can be in involved in various surveillance missions each day. The official says the virus infected the classified military computer systems that control the drones, but it has not “stopped the drones from flying worldwide.”
“Military officials are more concerned than panicked by this virus,” said Danger Room Editor Noah Schactman, who first reported the story last week for Wired magazine. “They’re just really not sure what’s going on. They’re not sure if it’s a deliberate attack. They’re not sure if it’s something accidental.”
The drones fly all over the world, but they are remote-piloted from American soil by pilots at Creech Air Force Base in Nevada. That’s where the virus was first detected.

The virus is logging each keystroke that the remote pilots input, and officials are trying to determine whether any classified information is actually being lost or sent outside the network. Schactman says the military has had a hard time wiping out the virus.

“They’ve tried over and over again to get rid of this thing using some fairly conventional methods, and they haven’t worked. And so it seems the only thing to get rid of this virus is to basically wipe the hard drives of these computers entirely and sort of rebuild the computers from scratch,” Schactman said.
But that can be an exhausting process: In 2008 removable hard drives introduced a virus into thousands of Defense Department computers, and to this day the Pentagon is still purging some machines. In the case of the computers that help coordinate the drones, care also has to be taken to back up all the information, so it isn’t lost during rebuilding.

The UAVs have become indispensable for military planners who depend on constant combat air patrols. But current and former Pentagon officials admit that technology cuts both ways. At the confirmation hearing for Defense Secretary Leon Panetta, former Deputy Defense Secretary William Lynn said bluntly, “In the 21st century, bits and bytes can be as threatening as bullets and bombs.” Lynn says even the National Defense University has been breached, and in a single intrusion this year 24,000 files were taken from a defense company. He says these are just some examples of a number of cyber intrusions over the past several years.

In June Lynn testified that “Some of the stolen data is mundane, like the specifications for small parts of tanks, airplanes and submarines. But a great deal of it concerns our most sensitive systems, including avionics, surveillance technologies, satellite communications systems and network security protocols. The cyber exploitation being perpetrated against the defense industry cuts across a wide swath of crucial military hardware, extending from missile tracking systems and satellite navigation devices to UAVs and the Joint Strike Fighter.” Perhaps most alarming, Lynn admitted that up till now, the US military had not been able to secure its systems. “Current countermeasures have not stopped this outflow of sensitive information,” Lynn said. “We need to do more to guard our digital storehouses of design innovation.”

Officials have not determined whether the virus introduced into the drone program is benign, or doing actual harm. An investigation is ongoing. Despite the fact the controls are not linked into any outside network, and therefore seemingly impervious to intrusion, the drone systems do have security issues. Noah Schactman says they still use external hard drives, and when they’re attached to the top-secret computers it can open them up to infection. He says the true danger of this virus comes not from an ability to “bring down a drone,” which is unlikely. Schactman says it comes down to trust. And he surmises that if officials come to think that the data they’re receiving from the unmanned vehicles has been compromised, they’re much less likely to view the information as safe and valuable.

Perhaps most alarming: the worst is yet to come. Even top Pentagon officials admit that more destructive tools are being developed, cyber weapons that have not yet been used. Former Deputy Secretary Lynn says, “And the most malicious actors have not yet obtained the most harmful capabilities. But this situation will not hold forever. There will eventually be a marriage of capability and intent, where those who mean us harm will gain the ability to launch damaging cyber attacks. We need to develop stronger defenses before this occurs.”

In August, a drone attack killed al Qaeda No. 2 Atiya Abdul Rahman in Pakistan. The most recent high-profile drone strike resulted in the death of U.S.-born militant cleric Anwar al-Awlaki in Yemen last month.

Is my mouse infected by virus?

September 7th, 2011

My mouse pointer tends to move automatically, even when the mouse is not being used. I suspect that there is a worm or virus doing this. I have tried to clean my computer using both paid and free security solutions, but nothing has solved the problem. I even tried formatting my system, but the problem still persists. What do you suggest?

- Drumil Merchant

Since you have already used various anti-virus solutions and formatted your PC, the problem might not be a worm or a virus but a problem with your hardware. First, try changing the port the mouse is connected to and check if the problem persists. Since, you have not mentioned which mouse you are using, try out the appropriate solution for the type of mouse you have.

If you have a trackball mouse, open the trackball compartment and take out the ball. You will see rollers on three sides, which have a tendency to collect dirt and lint. Gently clean each roller using a dry cloth and check the mouse. You may also need to clean lint off the ball. Some basic/budget optical mice have been known to cause a problem of random mouse pointer movement even when the mouse is not touched. This is mainly due to dust particles or debris getting stuck in or around the optical sensor underneath the mouse. You can try cleaning it using an ear bud, but be careful not to damage the sensor. If you are using a laser mouse, try changing the mousing surface (use a mouse pad).

The laser might be behaving erratically with the current surface, leading to random mouse movements. If the problem still persists, borrow a mouse from a friend and connect it to your system. You could also connect your existing mouse to another system to see if the problem re-occurs there. If the random movements continue, it is probably time to get another mouse.

Question: Please suggest a smartphone priced around Rs 20,000 that can play any video format and also allows me to edit MS Office documents.

- Bhushan Gadhari

Most Android smartphones can fulfill your needs. Many come with divX/xvid playback and document editors preinstalled. If not, you can install Moboplayer from the Android Market – it supports multiple video formats and plays them without any errors.

To edit MS Office documents, you can either purchase the Documents to Go app from the app market or if you want something free, you can try the Olive Office Premium app or Google docs for editing documents. We would recommend opting for the Samsung Galaxy S i9000 or LG Optimus Black – both priced around Rs 20,000.

Protection Against Virus Threat

December 25th, 2010

Information and communication technology, ICT, has changed much throughout the years and is constantly evolving to enrich our lives with its potential. The internet makes available a wealth of information and services from all around the world to everyone at the click of a button.

However, every good thing has its flaws and the internet is no different. The exponential growth in internet use exposes users to potential threats such as computer viruses and hackers that can mine personal information such as bank account details, access private emails and commit other cyber crimes such as the exploitation of children. One way of fighting off these dangers is by committing to cyber safety and security.

Anti-virus software helps to detect and remove computer viruses and other malicious programmes such as worms and trojans. The public are reminded to always remember to install anti-virus software in their computers – the anti-virus protection should be in use at all times, anti-virus software should be updated regularly, the computer should always be scanned after updating an anti-virus programme and the computer should be scanned regularly. As new viruses are being introduced on the internet almost everyday, users should ensure that their anti-virus software is always updated using the ‘live update’ feature to automatically check for updates.

A firewall is a software or hardware designed to block hackers from accessing your computer. It monitors communications between the computer and the network, and blocks unauthorised connections to the computer. A firewall can also block programmes residing in a person’s computer from sending out information to the internet without his approval. Users are also advised to always remember to install a firewall on their computer or home network; the firewall should be configured to prevent or block other computers on the internet from accessing the computer, the firewall should be configured to stop information in the computer from being sent out to the internet without the owner’s approval and the computer should be scanned periodically to check for security vulnerabilities.

Users should not open an email that has a suspicious title especially when they do not know the sender. Emails are commonly used to disseminate viruses, worms and trojans. Be very careful of acting on the contents of the email and opening files attached to an unknown sender. Such emails may be frauds or scams. Always scan all email attachments for viruses before opening them. Delete the email if the subject title appears suspicious or strange, even if the email is from someone you know. The person may have sent a virus unintentionally. Never open email attachments with file extensions as they are often used to propagate viruses.

Computer Problems And How To Fix Them

December 3rd, 2010

There are numerous computer problems that usually affect the computer, thus lowering its performance. The trick to fixing any computer related problem is to first find out where the problem is. Please read on to learn some tips that may help you find those problems and their recommended solutions.

Viruses are known to attack computers and may end up destroying vital information if not eliminated. You know that the computer has problems caused by viruses when it becomes extremely slow and applications take way too long or never respond at all. When this happens, get a strong anti-virus software program and carry out a full system scan to help find and remove the virus.

If you have been downloading and opening email attachments on a computer and it starts misbehaving, most probably it could have been attacked by malware. Common in the category of malware is the Trojan horse and worms which usually attack your files and may destroy the entire hard disk. For you to effectively do away with malware, consider doing a system restore and if it does not work, uninstall and then reinstall your operating system.

When the computer suddenly slows down in terms of its performance or you begin to notice some programs are being installed and you are not the one who is doing the installation, be prepared to deal with spyware. This is a type of malware which usually gets installed on your system and keeps collecting vital information on users each time without their knowledge. Once you are sure it is spyware, conduct a research on the internet and find out more on the freely available programs which will help you deal with it.

After doing a full virus scan and no viruses have been found but still find that the computer is running very slow, your disk could be the problem. Perform a disk clean up and carry out defragmentation on your hard disk to help organize it. Clear cache and history of websites that you visit to make your browser run faster.

Problems where the computer switches off on its own especially after a few minutes of usage are also common. This could occur as a result of overheating or it may be due to some other hardware faults. You can resolve this by switching off your computer and giving it a chance to cool down and if it still behaves the same way, you need to consider checking out your hardware components. Find a qualified person to assist you in working inside your computer if you do not have the technical know how.

As long as you can positively identify the various computer problems, the remaining part is not very difficult. Knowing where the problem is helps you find a solution to it. Do not forget to always conduct a back up for your system.

Even on the Gold Coast computer repairs are part of doing business in today’s worldwide marketplace. Find efficient and professional Gold Coast computer services to provide counsel and support.

Stuxnet virus exposes computer risks

October 31st, 2010

Over the past month, considerable attention has been directed at reports of a major cyberattack against the Iranian nuclear program. Allegedly, a highly complex piece of computer malware, called Stuxnet, affected the operations of the Iranian nuclear reactor at Bushehr and/or the uranium enrichment facility at Natanz. While we cannot be sure of details regarding possible accident scenarios at either of these facilities, reports have surfaced in the computer security community that the Iranian government is actively seeking talent familiar with the configuration and deployment of the process control computer systems. The pay: $20,000 a week.

So what is Stuxnet and why should we care (setting aside our Iran concerns)? Blogger Bryan McGrath has declared it “the first cyber smart bomb” and “600 kilobytes of War 2.0.” Much like a real smart bomb, Stuxnet was directed at a single target, limiting the potential for collateral damage. According to computer security software maker Symantec, nearly 60 percent of all Stuxnet infections were registered in a single country: Iran.

Stuxnet is a very small program, no bigger than a spreadsheet or document you might attach to an e-mail, but it does many things. It is able to rewrite instructions on programmable logic controller (PLC) computers, which are the brains of supervisory control and data acquisition (SCADA) process control systems. What does this mean? Take the analogy of the family automobile. Imagine someone was able to adjust the speed at which the belts or timing chain ran or shut off some of the fuel injectors or some other function of the engine by tampering with the onboard computer under the hood. Depending on how the car’s computer was tweaked, eventually you’d find yourself at the shop, maybe with the engine completely machine-gunned. Stuxnet does the same for computers attached to pipelines or assembly lines.

Industrial computer systems deliver instructions to real pieces of hardware on pipelines and electrical grids opening valves and flipping switches. This is work that used to be done by human beings, much like telephone calls used to be completed by real operators at switchboards. PLC computers take people out of the loop; they collect data from sensors and then activate resources in response. When we hear mention of items like “smart grid” or “smart field,” we are being told of how PLCs can more efficiently manage the distribution of resources and bolster the economic bottom line.

What is worrisome is to consider how these smart systems “phone home” to the management offices of the companies employing them. Desired in SCADA implementations is the capacity to see what is going on across the enterprise, to hold a clear picture of operations. Managers can investigate problems virtually and if necessary dispatch technicians to make a repair. But communications must pass in both directions, and to make the investment worth it, those communications should come at little cost. What this translates to is employment of the world’s communications backbone, the Internet.

While these communications may be cheap, those implementing Internet-enabled SCADA systems must confront the cost of opening their operations to the threats that may be delivered via the Internet. Stuxnet, the malware smart bomb giving the Iranians fits, may be deposited in two ways — by USB memory stick or propagation across the Internet. The instance of Stuxnet that hit the Iranians was most likely delivered by the former method, with some guileful clandestine operative plugging the USB stick into the effected PLCs. That should make for a good movie plot.

What will also make for good cinema, but a bad day for anyone affected, is when the next Stuxnet crashes out an electrical grid, upstream oil-and-gas operation or hospital medical data system here. We are taking critical infrastructure online, and while my colleagues and I argued some time ago in this newspaper that hacking the electrical grid was unlikely, the time for complacency has passed. Adding “smart” to our critical infrastructures does not necessarily make us safe. We should be prepared to put a great deal of thought and investment into the security of these systems as they are exposed to the risks involved in touching the Internet.
