How To Investigate Cyber Crime (Part-2)
Dear Friends,
In my last post I promised to continue this article in a simple manner and easy understandable language so that everybody even a going to be retired police officer can understand and my article becomes helpful to them to investigate the Cyber Crime related cases. My expert friends are requested to share there knowledge here for new cyber crime investigators, who thinks it difficult to investigate the cyber crime related cases.
So first of all I will tell them that don't get afraid by hearing a complaint from a victim about cyber crime as most of the complaint in the PS label are very easy to investigate. My friends, who can investigate murder cases, theft cases, cheating and other cases which are regular crime in our daily life and know what evidences should be collected from mobile number and device, can easily investigate cyber crime related offense. So just listen the complaint of a victim and give him/her a relief and don't say that you can't as that makes you inefficient before that citizen and in coming days in most of the cases computer or communication device will be part and parcel of the weapon of the criminal.
So my friends lets start from here. First of all I want to bring in your notice : -
What are the Basic Knowledge:-
1) You should know how to use mobile phone and what mobile phone does. ( I think all of us know this as this is part and parcel in all of our life as today a day labour also carry mobile phone with him)
2) Common sense of investigating other cases. ( All the police officers do have it)
3) To have a little bit knowledge in computer. ( I think this is also in possession with all of my friends)
4) A little bit knowledge about internet, email id, and how internet works. ( Some of my friends do have this but I will discuss it in my next article for those who does not have the knowledge and its very easy)
What are Cyber Crimes and how these are committed:- This has already been discussed in my blog earlier but inspite of that I will discuss you serially as if you don't know the crime and modus operandi of criminals how you will solve the problem. In a sentence cyber crime is defined as " Any illigal act involving a computer, its systems, or its applications" by EC Council. Cyber Crime is intentional and not accidental.
How To Take Complaint from Victim:- It will also be discussed in the next day.
What is Cyber Forensic:- All the investigators have idea about scientific investigation in other type of regular life cases and so they have idea about forensic science but cyber forensic is a different field and I will discuss it later and this is also easy understandable if anyone wants to understand from the experience of daily life.
I hope this will help you my friend. So pl keep visit regular for its update.
With Lots of Love

How To Investigate Cyber Crime
Dear Friends,
Many of my friends of my profession request me to write something about " How to investigate Cyber Crime Cases " in a simple language so that everyone even a lay man can understand and it becomes helpful to the aged police personnel for investigating cyber crime cases. Now a days the police officers above 40+ get afraid during investigating cyber crime cases. I have experienced in my professional life that when a police officer of 40+ hears about cyber crime in Police Station label , he misguides the victim by saying that there is no infrastructure to investigate the case in PS label so advises the victim to go to specialized wing for lodging complaint.
That is why I have started to write on this topic for making it easy understandable to all the investigators even a going to be a retired police officer, who has minimum knowledge of using mobile phone.
That's all for today. Pl visit regularly for knowing step by step about how to investigate cyber crime related cases.
Expert police officers in this field are requested to share their experience here for helping other police officers and I hope my expert friends of this field will stretch their helping hand to me.
With Thanks,
Sujit

How To Identify 419 Scammers Phone
Hi Friends,
After long long and long interval I am again infront of you with a valuable information, which I have got from my friend of cyber crime investigation field, who gave me the link of "joewein.de", and I am bringing this in front of you as this will help you a lot for identifying the 419 spammers. So here is the details of that information as published by that website.
Scam phone numbers in the United Kingdom (+44):
If an email mentions a UK phone number starting with +4470, it usually means that the sender of that mail is not in the UK at all and it is almost guaranteed to be a scam.
Usually the presence of a +44 70 number in a 419 scam email means you're dealing with criminals based in Nigeria who are using these numbers to make people believe they're dealing with someone legitimate who is in the UK instead of a criminal in an Internet cafe on a different continent.
Do not reply to any emails that mention +4470 phone numbers!
Never call such numbers!
Break off all contact with these people!
The scammer most likely is NOT based in the UK. +44 70 numbers belong to international call forwarding services. Their whole point is that people can reach the user of the number when he's not in the UK. These services make it possible for scammers to hide the fact that they are based in Nigeria or other countries in Africa, while the scam victim will believe they're dealing with someone in the UK. Very few (if any) legitimate individuals use these numbers. Banks, law offices, UK immigration officials, etc. never use +44 70 numbers because, since their offices are based in the UK, they have no need to redirect calls to their offices to sohttp://www.blogger.com/img/blank.gifme mobile phone outside the UK. We have not come across any legitimate UK businesses yet that use +44 70 numbers. Their only visible user base are scammers in Nigeria, South Africa and elsewhere. It is a perfect mystery to us why the UK authorities allow these services to continue operating despite them being used almost exclusively by criminals.
UK phone numbers starting with '70' are "Personal numbering" in the "Find me anywhere" range. Charges for calls to these numbers are not distance-dependent. They can cost as much as UKL 0.50 (USD 0.90) per minute to call and can forward the call to virtually any phone number in the world. Forwarding numbers can be set up for free and completely anonymously via websites such as uknumbers.com.
So my friends be cautious about them and for more information in details about the spammers please visit here
With lots of love

How To Trace/Search Stolen Laptop Part-3
Dear Friends,
In my earlier two parts (Part-1 and Part-2) I discussed about some important terms and logics behind my idea so that my friends can understand my point and they can enrich it with their valuable opinions. And in this third point I have started it as "How to find stolen laptop" as this will be helpful for law enforcing agencies and also other civilians.
So lets come to the original point.
I have already discussed in my earlier parts that laptop can't be traced like mobile phones by using its MAC number like IMEI in case of mobile but at the same time you have also learnt from there that MAC is an unique identifier and your duty is to note the MAC address in a separate place for your future need in case of laptop theft.
I think more or less 98% of laptop users go to internet and they use Antivirus for their Laptops and almost all the antivirus are updated through internet and not only that all the paid Antiviruses are either single user or a limited number of users, which means u can install that antivirus in either single machine or a limited number of machine and if the installation crosses the limit it stops to function in those systems/laptops. So I think now you have understood what I am going to say.
Yes my friend I am going to tell about the unique identifier of your laptop has already been registered in the server of your Antivirus during the time of activation and updatation in the net. There is another unique identifier in your laptop. That is hardware serial number and it can't be changed but you can't get it though any command except using tools/softwares like DEFT ,HELIX3 PRO and others and you can't get these easily. But your laptop manufacturer has this in their record. And I think this is also registered in the the server of your Antivirus.
So I want to say my Police friends that don't sent any request to the ISPs about searching of MAC of stolen Laptops in their network but you can send it to the Antivirus companies, who are running business in your country and in this case you must need support from your Government for passing legislation to compel Antivirus Companies to help police if they want to run their business in your Country and at the same time they must supply the hardware serial number of the laptop to their customers in the bill during selling the product.
And if this system is imposed in your state you need not to spend a single penny for using third party software like laptop tracker for tracking the stolen laptop as all the Govt. are liable to see the interest of their citizen and for this Govt. need not to pay a penny for you.
This was the technical part, which can help you but at the same time you can take help of this website. This is good effort of Quick Heal for the netizens.
Waiting for your comments and opinion on this.
Thanking you
Sujit
