MrBlack Malware

Up to 80 percent of the top-selling home routers on the market are vulnerable to attacks, according to an April 2015 article on Techworld. Because of the lack of basic security practices on the part of Internet service providers (ISPs), there are a number of hacker-controlled routers used to launch distributed denial-of-service (DDoS) attacks. Computer repair experts point out that the Linux Spike Trojan malware nicknamed “MrBlack,” which security firm Incapsula discovered in December 2014, is one of the more prevalent, spanning 109 countries and over 40,000 routers in small offices and home offices.

MrBlack’s Misdeeds

MrBlack is malware that infects routers and spreads to other devices. Sometimes, infected routers search for open secure shell (SSH) ports and access them using the device’s default credentials. In other words, the malware infects routers that still have default security credentials so they can access the device remotely. After infecting a router, MrBlack and its variants perform tasks like cookie hijacking, man-in-the-middle (MITM) attacks, eavesdropping on communications, and accessing local network devices.

Incapsula found that the hardest hit routers are those made by Ubiquiti, which the company leases on a monthly basis. While most of the command and control centers that launched attacks are in Asia, where Ubiquiti hardware is largely available, 21.7 percent are in the U.S. In regards to computer repair, Portland experts warn that anyone with lenient router credentials may be at risk for a similar type of attack.

How to Protect Routers at Home and Your Business

  • Change the router’s default login and password settings.
  • Disable remote management over the Internet. If you need remote management capabilities, change the password often.
  • Log out of the router’s website after making changes to your account.
  • Turn off Universal Plug and Play (UPnP) support.
  • Turn on Wi-Fi Protected Access (WPA) encryption and turn off the Wi-Fi Protected Setup (WPS) to connect new devices.
  • Avoid using default IP ranges such as 10.0.0.1, 192.168.0.1, 192.168.1.1 and 192.168.2.1. Instead, use 9.8.7 or something similar to prevent Cross-Sit Request (CSRF) attacks.
  • Install the latest router firmware, if available.

How to Decide Whether you Need Computer Repair or Replacement

As your computer ages and starts needing repairs, it’s natural to wonder whether you should invest in computer repair or simply purchase a new system. As you ponder this conundrum, consider the cost of the repair, the issue at hand, and the benefits of getting a new computer.

Problem: Data Loss

If your computer won’t turn on or you can’t access your files, first look into computer repair services. If you’re lucky, the problem will be a quick fix such as a simple part replacement. On the other hand, a quick fix may also result in lost data.

Data recovery can cost hundreds to thousands of dollars, so it’s best to have a backup plan before it happens. If the computer repair cost is more than 50 percent of the system’s original value, or the computer is more than 5 years old, a new computer may be best.

Problem: Virus

Viruses give computer repair services the most business. Repair technicians can eradicate most viruses, so this is often a viable option. However, if a virus is particularly malicious and gives your computer chronic problems – despite the computer repair shop’s best efforts to scrub it out – your money may be better spent on a new computer and good antivirus software.

Problem: Physical Damage

Dropping, spilling liquid on, or overheating your computer can cost you $300-500 or more. After you get a repair estimate from a shop, it’s wise to weigh the cost of fixing the computer against its age. If you’ve had the computer for more than five years, or if the cost is 50 percent of the original price, we recommend replacing it.

Having to repair your computer can be frustrating. If you’re having a tough time deciding whether to replace or repair it, a trustworthy computer repair professional can offer valuable advice.

Happy Hamster Computers’ ‘No Landfill’ Philosophy

The fossil fuels used to create the average desktop computer and monitor weigh at least 10 times more than the finished electronic devices. Plus, the manufacturing process involves the use of more than 700 chemicals such as mercury, chromium, cadmium, and other heavy metals. The cathode ray tubes in monitors can contain up to 8 pounds of lead, a substance known to cause birth defects, cancer, and neurological disorders. When these chemicals aren’t disposed of properly, they can leach into the soil, from which they pollute the local water supply and ecosystems.

Happy Hamster’s Green Approach

With the cost of new computers going down, more than 10 million old systems are getting dumped into landfills every year. Before throwing away a broken computer, Happy Hamster encourages consumers to take a greener approach by first seeing whether the issue can be fixed with a simple computer repair.

If computer repair services aren’t a cost-effective option for you, or your system is old, the next best option is to recycle it. Several manufacturers will recycle your old system free of charge, and some local dumps offer a recycling program for electronics. Alternatively, you can donate your old computer to a nonprofit like FreeGeek.org, which will refurbish and donate it to a school or community organization in need.

Tips for Green Computer Use

To prolong the life of your computer, follow simple energy-saving practices. Turn your computer (and monitor) off when you’re not using it. If you plan to use it again within a couple of hours, at least put it in “sleep” mode and turn off the monitor.
