Your friend becomes enemy !

You might receive a message from someone who you know, but the message seems to be strange. It might be your friend, family, colleague and other people that you know and trust them. This message or could be in form of email or instant messages (IM) or be post in forum or wall on behalf of your friend and from his or her account. These messages might contain attachments or link to website or just be spam like message that advertise something. These messages might send in these ways:

1)      Send through emails

2)      Post in forum or social network discussions such as Facebook

3)      Post as comment in places that accept posting comment (e.g. you post photo and you lets your friend to post comment there)

4)      Send with SMS from your friend’s phone

What you see in first place is that your friend actually sends them, but it might be strange that your friend does that and sometimes it might be normal. You might see following contains in your messages:

1)      Ask you to visit a website for new photo , news , product or something interesting

2)      Ask you to open attachment that contains photo, document, movie, music…

3)      Show some advertisement , such as buy this product

4)      Ask you to do a favor in urgent, for example ask you to send a money immediately due to some emergency issues

5)      Ask you to download a program or software

Some of these actions might be normal, for example you and your friends and family members would exchange pictures by email or share link to visit a website for something interesting but it would be strange because in this case attachment might contains Malware (Virus, Worm, Trojan …) . Links might lead you a website that contains Malware. Your friend will never ask for emergency issue by email, they would probably call you. Firstly, you have to detect these types of issues, for example if you receive an email from your friend asking you to send money to his or her account, it is better to contact your friend and discuss this, because your friend might NOT send that message. When you open attachment take a look at format of email and also it is better to make sure your Anti-Virus is update and real time protection is running before open the attachment. Don’t just click any links that comes from your friend and see the link and format of email and see it sounds like your friend or not. For example, if your friend asks you to see new photo, then will write it this way:

Dear <Your real name>

I come back from my vacation (this should be something that your already know, perhaps your friend talk about it before). I attached my photo in this email take a look

Good luck,

<Your friend’s real name>

 

But you might see an strange email for example your friend talked about vacation but he or she never went there because didn’t told you and also email instead of write your name it would write your email id and also won’t write your friend real name. And if you see carefully, you would see it is in different format and style of your friend’s email. For example it might be like this:

Hey, check my new vacation photo

You might wonder, that your friend won’t write this way in email. In some smart technique of this trick it might put your name and it will scan from your email profile where you’re enter your name but they don’t know about style of your friend’s writing when send an email for you. Sometimes these emails might be too tricky and you accidently open them and then Anti-Virus detects something. In that case, this is sign of issue.

So what’s happens? In these case your friend’s account or computer been compromise, it might be a person that done that or in most of the time it is a software such as Malware (Virus, Worm, Trojan…) doing this automatically after they infect your friends system.  In this case, you shouldn’t open any email that comes from your friend that sending strange message and instead try to contact him or her by phone or visiting your friend place if possible and ask your friend to do these steps:

1)      Log in to Microsoft Safety Scanner and download the tools and run full system scan

2)      If your friend running Anti-Virus ask to check for update and also check and make sure subscription didn’t expire

3)      Check Firewall and Windows Security Center/Action Center

4)      If it was SMS message that been sent, check Mobile Phone for virus, in some cases you could connect your phone to PC and scan folders for Malware using your Anti-Virus in your PC or scan it with Anti-Virus for Mobile Phones.

5)      If there is no Anti-Virus in the system consider to get one such as Microsoft Security Essentials

When you do above checking for your friend, you might see something, such as presence of some Malware or issues with Anti-Virus or Security and they you should solve them. There might be a case that PC is normally fine and nothing is wrong with that. In that case ask your friend about places that he or she login to check the account that been compromise and then you probably we see that he or she might check email, social network or login using a PC that was infected such as some of unsafe public PCs. In that case try to guess those places and avoid using those PC for checking email and entering any password. Then once you find the root of issue, and then do these steps:

1)      Change passwords for compromised email and make sure new password is strong

2)      Ask your friend to contact all of his friends in contact list and tell them about issue and ask them to remove suspected email send from his or her account(Tip: use BCC field in email instead of CC or To field, it will helps that receiver only view your email NOT other contacts)

3)      Check your bank and other services that associate with compromised email, to make sure they are not affected and if they affected contact their support (For example check your bank account and if your money been withdrawn illegally, contact your bank).

4)      Also, if you use same password as compromised services for other things such as other emails or services , it is better to change password of those services( For example, if you password for email that been compromised is same as password that you use for Facebook, it is better to change your Facebook password too)

 

In this era of cybercrime, you should take care of yourself and your friends when you are using Internet and Internet Services.
