Slide 10: 

Virus, Worms and Trojan attacks: Viruses are basically programs that are attached to a file which then gets circulated to other files and gradually to other computers in the network. Worms unlike Viruses do not need a host for attachments they make copies of themselves and do this repeatedly hence eating up all the memory of the computer. Trojans are unauthorized programs which functions from inside what seems to be an authorized program, thereby concealing what it is actually doing. Wednesday,Feb 03, 2010 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com 10

Computer Viruses : 

Computer Viruses Viruses A computer virus is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of it. Note that a program does not have to perform outright damage (such as deleting or corrupting files) in order to be called a "virus".

Case Study- BPO Data Theft : 

Case Study- BPO Data Theft The recently reported case of a Bank Fraud in Pune in which some ex employees of  BPO arm of MPhasis Ltd MsourcE, defrauded US Customers of Citi Bank to the tune of RS 1.5 crores has raised concerns of many kinds including the role of "Data Protection". Wednesday,Feb 03, 2010 29 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Case Study (contd.) : 

Case Study (contd.) The crime was obviously committed using "Unauthorized Access" to the "Electronic Account Space" of the customers. It is therefore firmly within the domain of "Cyber Crimes". ITA-2000 is versatile enough to accommodate the aspects of crime not covered by ITA-2000 but covered by other statutes since any IPC offence committed with the use of "Electronic Documents" can be considered as a crime with the use of a "Written Documents". "Cheating", "Conspiracy", "Breach of Trust" etc are therefore applicable in the above case in addition to section in ITA-2000. Under ITA-2000 the offence is recognized both under Section 66 and Section 43. Accordingly, the persons involved are liable for imprisonment and fine as well as a liability to pay damage to the victims to the maximum extent of Rs 1 crore per victim for which the "Adjudication Process" can be invoked. Wednesday,Feb 03, 2010 30 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Case Study (contd.) : 

Case Study (contd.) The BPO is liable for lack of security that enabled the commission of the fraud as well as because of the vicarious responsibility for the ex-employee's involvement. The process of getting the PIN number was during the tenure of the persons as "Employees" and hence the organization is responsible for the crime. Some of the persons who have assisted others in the commission of the crime even though they may not be directly involved as beneficiaries will also be liable under Section 43 of ITA-2000. Under Section 79 and Section 85 of ITA-2000, vicarious responsibilities are indicated both for the BPO and the Bank on the grounds of "Lack of Due Diligence". At the same time, if the crime is investigated in India under ITA-2000, then the fact that the Bank was not using digital signatures for authenticating the customer instructions is a matter which would amount to gross negligence on the part of the Bank. (However, in this particular case since the victims appear to be US Citizens and the Bank itself is US based, the crime may come under the jurisdiction of the US courts and not Indian Courts). Wednesday,Feb 03, 2010 31 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

The Information Technology (Amendment) Act, 2008 has come into force on 27th October, 2009. : 

The Information Technology (Amendment) Act, 2008 has come into force on 27th October, 2009. Almost Nine years and 10 days after the birth of cyber laws in India, the new improved cyber law regime in India has become a reality. The Information Technology Act initially came into force on 17th October 2000 on the model UNCITRAL of UNO 1996. Major changes to the IT Act 2000 have now come into force with effect from 27th October 2009. There are around 17 changes and out of that most of the changes relate to cyber crimes. The last decade has seen a spurt in crimes like cyber stalking and voyeurism, cyber pornography, email frauds, phishing and crimes through social networking. All these and more are severely dealt with under the new laws. Wednesday,Feb 03, 2010 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com 38

Some of the major modifications  are: : 

Some of the major modifications  are: 1. A special liability has been imposed on call centers, BPOs, banks and others who hold or handle sensitive personal data. If they are negligent in "implementing and maintaining reasonable security practices and procedures", they will be liable to pay compensation. It may be recalled that India's first major BPO related scam was the multi crore MphasiS-Citibank funds siphoning case in 2005. Under the new law, in such cases, the BPOs and call centers could also be made liable if they have not implemented proper security measures. 2. Compensation on cyber crimes like spreading viruses, copying data, unauthorised access, denial of service etc is not restricted to Rs 1 crore anymore. The Adjudicating Officers will have jurisdiction for cases where the claim is upto Rs. 5 crore. Above that the case will need to be filed before the civil courts.

REAL CYBER FORENSIC CHALLENGE IS YET TO COME.. …. Wednesday,Feb 03, 2010 89 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Slide 90: 

Awareness: Technology is changing very rapidly. So does the increase in Cyber crimes, No proper awareness shared with regard to crime and latest tools. People are so ignorant that makes it effortless for cyber criminals to attack. People fear to report crimes and some crimes are not properly recorded. The reason behind this is that the victim is either scared of police harassment or wrong media publicity. For minority and marginalised groups who already bear the brunt of media bias, reporting online harassment to the police may simply draw further unwanted attention. The public is not aware of the resources and services that law enforcement could provide them if being a victim of crime or witness. Challenges faced by Law Enforcement Wednesday,Feb 03, 2010 90 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Slide 91: 

Technical Issues: Large amount of storage space required for storing the imaged evidences and also for storing retrieved evidence after analysis. Retrieved evidence might contain documents, pictures, videos and audio files which takes up a lot of space. Technical issues can further be categorised into software and hardware issues. Wednesday,Feb 03, 2010 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com 91

Slide 92: 

Software and Hardware Issues: The growth of Cyber crime as given rise to numerous Forensic software vendors. The challenge being to choose among them and no single forensic tool solves the entire case, there are loads of third party tools available. So is the case with Hardware tools, Most common and liable h/w tool is the FRED. But when it comes to Mobile forensics it is a challenge to decide the compatibility of different phones and which h/w to rely on.. Wednesday,Feb 03, 2010 92 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Future Course of Action : 

Future Course of Action Recently China has been manufacturing mobile phones that have cloned IME numbers which is a current challenge faced in Mobile forensics. Information sharing: Information sharing is a best practice and can be accomplished by a variety of means such as interacting with industry groups, attending briefings, meetings, seminars and conferences, and working actively with forensic bodies like CDAC.. Wednesday,Feb 03, 2010 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com 93

Slide 94: 

Inadequate Training and Funds: Due to the growing of cyber forensic tools law enforcement does not get adequate training and awareness on innovative tools. Training bodies are limited and are pricey. Insufficient funding in order to send officers for training and investing on future enhancements. Transfers and recruiting officers adds to the loss of experienced staff and spending for training the newcomers. Cases become pending in such circumstances. Wednesday,Feb 03, 2010 94 Dr. Tabrez ahmad, www.site.technolexindia.com, http://technolexindia.blogspot.com

Slide 95: 

Global Issues: Most of the IP addresses retrieved during investigation leads to servers or computers located abroad which have no identity, hence further investigations are blocked and closed. Correspondence with bodies such as Google, Yahoo, Hotmail is quite time consuming and prolong the investigations. Wireless or Wi-Fi, Bluetooth, Infrared Issues: Latest wireless technologies which provide internet connections causes exploitation especially when it is not secured. This is the present technology terrorists and radical activists exploit. This is another vulnerability that law enforcement faces.

Future Course of Action (Contd.) : 

Future Course of Action (Contd.) Mumbai Cyber lab is a joint initiative of Mumbai police and NASSCOM –more exchange and coordination of this kind More Public awareness campaigns Training of police officers to effectively combat cyber crimes More Cyber crime police cells set up across the country Effective E-surveillance Websites aid in creating awareness and encouraging reporting of cyber crime cases. Specialised Training of forensic investigators and experts Active coordination between police and other law enforcement agencies and authorities is required.
