Fellow Blogger TechPaul, has advised his readers this morning, that chat messages are scaring users into installing malware in his article – Skype Phishing Returns. If you use Skype chat, or for that matter any other chat application, you need to be aware of this information.
This presents an opportunity to re-run a popular article previously posted on this site, setting out the precaution we all need to take when using any type of chat client.
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.
But, and there always seems to be a “but” lately – 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.
As Wikipedia explains it, 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 that connects him or her, to a website that then downloads malicious code. Viruses, worms, and Trojans typically propagate by sending themselves rapidly through the infected user’s buddy list.
Follow these tips to ensure you are protected when using instant messaging.
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.
The risk here goes beyond malware, as sadly, they could come into contact with undesirable, or even dangerous individuals. The risk is low of course, but……..
