Another Worm Worms Its Way Into Instant Messaging Applications

imageFrom the more things change the more they remain the same files:

AV-killing worm spreads via Facebook chat and IM clients – A rather industrious piece of malware that – among other things – paves the way for other malware by disabling AV solutions and software update modules has been spotted spreading via several Instant Messaging applications (ICQ, Skype, GTalk, Pidgin, MSN, YIM) and Facebook.

The victims receive a message from an unknown user, offering a link to a funny or interesting video. If they follow it, the malware in question downloads automatically from the linked site and is executed.

Nothing new here – as any one of the 10 or more articles I’ve  written over the years on using Instant Messenger applications safely will attest to. The following post (originally published September 4, 2010) will serve as a quick refresher on how to navigate the Internet safely while using an Instant Messenger client.

Tips For Using Instant Messenger Applications Safely

In a recent Symantec survey, which questioned computer users on the most likely routes cybercriminals use to drop malware on unsuspecting users, one resultant statistic made me sit up a little straighter. Just 3.9% of survey participants believed that Instant Messenger applications had a role in malware distribution.

Given the frequency with which instant messaging is used to distribute malware (recent statistics indicate almost 50% of worms use this method to spread), I was more than a little surprised at this unrealistic response.

The reality is, from a security perspective Instant Messaging applications can present considerable security risks. Security breakdowns can occur when these programs are used to share files, folders, or in some cases, entire drives. Instant messaging, unfortunately, is a primary channel used by cyber-criminals to distribute malware and scams.

Programs such as MSN Messenger, Yahoo! Messenger, AIM, and a basket full of other IM applications, are extremely popular with users who want real-time contact with each other and (no surprise here), this makes them the perfect vehicle for cyber criminals.

Hackers use two methods of delivering malicious code through IM: delivery of virus, Trojan, or spy ware within an infected file, and the use of “socially engineered” text with a web address that entices the recipient to click on a URL which connects to a website that downloads malicious code. Viruses, worms, and Trojans then typically propagate, by sending themselves rapidly through the infected user’s buddy list.

The following is a series of sensible tips for users to get the most out of these programs, securely and responsibly.

As with any other application you use on the Internet, having the knowledge that allows you to use it safely, and being aware of current threats, will make for a more positive experience when using these wildly popular applications.

Don’t click on links, or download files from unknown sources. You need to be alert to the dangers in clicking on links, or downloading files from sources that are not known to you. Even if the files or links apparently come from someone you know, you have to be positive that it really was this person who has sent the message.

Check with your contact to be sure the files, or links are genuine. Remember, if you click on those links, or run those attachments without confirmation, you run the risk of letting malware into your computer.

Use only secure passwords, and be sure to change them regularly. The longer and more varied they are – using a variety of different characters and numbers – the more secure they will be.

Protect personal and confidential information when using IM. Revealing confidential or personal information in these types of conversations, can make you an easy target for Internet predators.

For added protection when using a public computer, ensure that you disable any features that retain login information to prevent other users from gaining access to your instant messaging once you leave.

It’s virtually impossible to avoid publishing your email address on the Internet, however do so only when absolutely necessary. Cyber criminals are always on the lookout for accounts to target.

Instant messaging, unfortunately, is a primary channel used by cyber-criminals to distribute malware and scams.

Just a few days ago, for example, a Trend Micro analyst discovered an IM variant of the “Solve the IQ test”. Had he followed the instructions, he could have let himself in for a series of monthly charges of $9.99–$19.99 a month, automatically added to his cell phone bill.

Steal Your Friends’ Instant Messenger Passwords – No Kidding!

The use of instant messaging for rapid communication, as opposed to voice contact, is a phenomenon that I must admit, has never appealed to me.

The reality is however, that programs such as MSN Messenger, Yahoo! Messenger, AIM, and a basket full of other IM applications, are extremely popular.

If you are an IM convert what would you think if you came across an application that advertised as follows? –

“Apheve Pro is a great piece of software which contains a key feature of disguising as multiple instant messaging services including Windows Live Messenger, Yahoo! and Skype. This program would be perfect for if you have the annoying visitor coming round who wants to sign in to their IM account”.

Pretty cool, huh? Imagine, a free application designed specifically to help you steal Instant Messenger logins including MSN Messenger, Yahoo IM and Skype as mentioned in the blurb above.

On the other hand, like me, you might feel disgusted, revolted, or just plain pi**ed off that such a piece of obviously illegal software is freely available on the internet.

Apheve

There is nothing to be gained by describing how this piece of crap works. It is sufficient to say that it works; and it works far too well!

Since this application can be deployed in diverse locations including the workplace, schools, libraries, and so on, it is obviously a very dangerous hacking tool.

As I have said numerous times on this site, from a security perspective these applications can present considerable security risks. We can now add one more.

Follow these tips to ensure you are protected when using instant messaging.

For added protection when using a public computer, ensure that you disable any features that retain login information to prevent other users from gaining access to your instant messaging once you leave.

Instant Messaging Safety Tips

I’m always amazed when I see my younger friends communicating with each other using instant messaging applications. Their use of instant messaging for rapid communication, as opposed to voice contact, is a phenomenon that I must admit has never appealed to me.

I excuse myself on this one by convincing myself that I’m an ancient fossil; after all my computing experience goes all the way back to the dark ages of MS-DOS 1. Not quite the days of the Dinosaurs; but close.

My comfort zone in communications is a telephone, used the old fashioned way for immediacy, or email where immediacy is not an issue. The reality is however, that programs such as MSN Messenger, Yahoo! Messenger, AIM, and a basket full of other IM applications, are extremely popular with the younger generation, like my younger friends, who want real-time contact with each other.

Regrettably, from a security perspective these applications can present considerable security risks. Generally, security risks occur when these programs are used to share files, folders, or in some cases even entire drives. Instant messaging, unfortunately, is a primary channel used by cyber-criminals to distribute malware.
