What exactly is AAEH?
Today, the US-Cert (United States Computer Emergency Readiness Team) released a security alert concerning the AAEH security threat.
AAEH is a group of malicious software downloads that exists in many different forms, all designed to wreak havoc on computers and networks. It may be a “password stealer” that records your passwords as you perform online banking, log into credit card accounts and the like. It could be in the form of a rootkit, a “clandestine computer program designed to provide continued privileged access to a computer while actively hiding its presence.” Or it may present itself as a fake anti-virus, tricking you into “installing” it on your computer. Lastly, it has been seen in the form of ransomware that will encrypt computer key files and then demand payment in order to return the files to a readable state.
Once a user has downloaded any of the various forms of AAEH, it begins to mutate, which makes it very hard to defend against from a reactive point of view. Even worse, if the infected computer is on a network, the malicious software morphs every few hours and rapidly spreads across to other users. AAEH has also been known to block access to well known anti-virus websites, so that infected users don’t stand a chance at getting help. The best known defense against AAEH and any other malware is to be proactive when it comes to your computers and networks.
How to defend against the AAEH Security Threat
Be sure that you have a solid Anti-Virus solution in place and that it is kept up-to-date with the latest virus definitions.
We often see users who install anti-virus and then never perform any updates after that installation, not realizing that by doing so they are leaving their systems completely open to attack. If you have a multiple user network, opting for a managed anti-virus system can save you the headache of managing multiple installations and updates.
Install Updates for Your Operating System and other Software
Installing Windows® updates and updates for any other installed software is a strong defense against threats such as these. Microsoft®, Adobe®, and other software companies release these updates to fix known security problems or vulnerabilities. When you choose not to install them, you are making a way for hackers to easily exploit your systems. It’s like leaving your front door unlocked with a sign in the window that no one is home.
Employ a Reliable Backup System
Even the most careful users need a solid backup they can depend on. Whether it’s accidentally deleting a valuable file, folder corruption or a full-on malicious attack like these, make sure you protect your data with a good quality backup system. Also, don’t set it and forget it. Test and check to ensure that the backup is working properly and that you can restore the files when you need them most.
