These predators are intent on stealing your money and personal information, installing damaging programs on your computer, or misleading you with an online scam.
Cyber-crooks are relentless in their pursuit of your money and “It’s all about the money,” according to Graham Cluley, senior technical consultant at Internet security firm Sophos. In the worst case scenario, your identity and your financial security can be severely compromised.
Looking at estimates provided by a number of Internet security companies, the consensus seems to be that there are over 11,000,000 malware programs currently in the ether. Various Internet security companies report having to deal with as many as 20,000 new versions of malware daily. Here’s the math; one new malware program every four seconds!
Since additional sophisticated threats are being developed, or are currently being deployed, some observers are of the opinion that the Internet is essentially broken. If you think this is an exaggeration, check this out and then you decide.
Tainted search engine results: Internet security gurus have known for some time that we can not rely on Internet search engine output to be untainted and free of potential harmful exposure to malware.
Cyber-crooks continue to be unrelenting in their chase to infect web search results, seeding malicious websites among the top results returned by these engines. When a potential victim visits one of these sites, the chances of downloading malicious code onto the computer by exploiting existing vulnerabilities, is extremely high.
Infected legitimate websites: According to an Internet security industry leader Sophos, over 90 percent of dangerous websites, that is – websites that are distributing Trojan horses and spyware – are legitimate sites that have been hacked through SQL injection.
It was reported recently that over sixteen thousand web pages were infected daily between January and June of this year; three times the rate of infection noted in the previous year. Work out the math, and you’ll find that’s one new infected legitimate website every five seconds!
More disturbing, seventy nine percent of compromised web pages tracked this year were on legitimate web sites; including web sites owned by Fortune 500 companies, government agencies and ironically, security vendors.
If you’re unfamiliar with the term, drive-by download, they are essentially programs that automatically download and install on your computer without your knowledge.
This action can occur while visiting an infected web site, opening an infected HTML email, or by clicking on a deceptive popup window. Often, more than one program is downloaded; for example, file sharing with tracking spyware is very common. It’s important to remember that this can take place without warning, or your approval.
Rogue software: Unless you have had the bad experience of installing this type of malicious software, you may not be aware that such a class of software even exists. But it does; and regrettably, it is becoming more widespread. Most rogue software uses social engineering to convince users’ to download this type of malicious software.
A rogue security application is an application, usually found on free download and adult websites, or it can be installed from rogue security software websites, using Trojans or manipulating Internet browser security holes.
After the installation of rogue security software the program launches fake or false malware detection warnings. Rogue security applications, and there seems to be an epidemic of them on the Internet currently, are developed to mislead uninformed computer users’ into downloading and paying for the “full” version of this bogus software, based on the false malware positives generated by the application.
Even if the full program fee is paid, rogue software continues to run as a background process incessantly reporting those fake or false malware detection warnings. Over time, this type of software will essentially destroy the victim’s computer operating system, making the machine unusable.
Some types of rogue security software have the potential to collect private and personal information from an infected machine which could include passwords, credit card details, and other sensitive information.
Email scams: Email scams work because the Cyber-crooks responsible use social engineering as the hook; in other words they exploit our curiosity. The fact is, we are all pretty curious creatures and let’s face it, who doesn’t like surprise emails? I think it’s safe to say, we all love to receive good news emails.
It seems that more and more these days, I get phishing emails in my inboxes all designed to trick me into revealing financial information that can be used to steal my money.
If you’re unfamiliar with phishing, it is defined as the act of tricking unsuspecting Internet users into revealing sensitive or private information. In a phishing attack, the attacker creates a set of circumstances where the potential victims are convinced that they are dealing with an authorized party. It relies for its success on the principle that asking a large number of people for this information, will always deceive at least some of those people.
A personal example of how this works is as follows. According to a recent email (similar in form and content to 20+ I receive each month), my online banking privileges with Bank of America had been blocked due to security concerns. This looked like an official email and the enclosed link made it simple to get this problem solved with just a mouse click. What could be easier than that?
Clicking on the link would have redirected me to a spoof page, comparable to the original site, and I would then have begun the process whereby the scammers would have stripped me of all the confidential information I was willing to provide.
My financial and personal details, had I entered them, would then have been harvested by the cyber-crooks behind this fraudulent scheme who would then have used this information to commit identity and financial theft.
These types of attacks against financial institutions, and consumers, are occurring with such frequency that the IC³ (Internet Crime Complaint Center), has called the situation “alarming”, so you need to be extremely vigilant.
Being involved in computer security, I am amazed and frankly frustrated, at the lack of knowledge exhibited by most typical computer users, and most importantly, the lack of knowledge concerning the need to secure their machines against the ever increasing risks on the Internet.
We now live in the age of the “Interconnectedness of All Things” in which we are beginning to see the development and availability of large numbers of Internet connected devices. There is no doubt that this will lend new strength to computer-aided crime and in this new political environment we now live in, perhaps even terrorists.
This is by no means an exhaustive list of the dangers we are exposed to on the Internet. There are many more technical reasons why the Internet is becoming progressively more dangerous which are outside the scope of this article, but one worth mentioning is the recent discovery that the very backbone of the Internet DNS can be compromised.
The Domain Name System serves as the “phone book” for the Internet by translating human-readable computer hostnames, e.g. http://www.example.com, into IP addresses, e.g. 220.127.116.11, which networking equipment needs to deliver information.
So what do you think? Is the Internet broken and if so, how can it be saved?
Be kind to your friends, relatives, and associates and let them know that all of the above dangers are now epidemic on the Internet. In that way, it raises the level of protection for all of us.
Be aware of the following security risks on the Internet:
Trojan horse programs
Back door and remote administration programs
Denial of service
Being an intermediary for another attack
Unprotected Window shares
Hidden file extensions
Review the following actions you can take to protect your Internet connected computer system:
Install an Internet Browser add-on such as WOT (my personal favorite), which provides detailed test results on a site’s safety; protecting you from security threats including spyware, adware, spam, viruses, browser exploits, and online scams.
Don’t open unknown email attachments
Don’t run programs of unknown origin
Disable hidden filename extensions
Keep all applications (including your operating system) patched
Turn off your computer or disconnect from the network when not in use
Disable scripting features in email programs
Make regular backups of critical data
Make a boot disk in case your computer is damaged or compromised
Turn off file and printer sharing on the computer.
Install a personal firewall on the computer.
Install anti-virus and anti-spyware software and ensure it is configured to automatically update when you are connected to the Internet.
Ensure the anti-virus software scans all e-mail attachments.
