The development of Internet
A cow was lost in Jan 14th 2003. If you know
where it is, please contact with me. My QQ number
is 87881405. QQ is one of the most popular IM in
China.

Computer Crime Vs Computer facilitated crime

Major categories of cyber facilitated crime
7
Hacking case HOW?Major categories of intrusion
technology used by hackers in the cases we
investigated
8
Hacking case HOW?

• The following intrusion methods increased rapidly
  in recent year and became one of the major
  intrusion technology
• Large-scale intrusion by exploiting vulnerability
  of client software
• Large-scale intrusion by decoying users to
  install malicious code through P2P, IM, Email
  network

9
Case example

• A virus on QQ (a most popular IM) were created to
  spread malware in order to creat an IRC botnet
  60,000 hosts were infected.

How did the criminal (hackers) occupy the
victim hosts?
Those who dont know a lot about technology make
profit by damage the network security
directly. Those who know technology make profit
by selling technology.
11
Hacking without knowledge of technologyCase
example Netbank accounts stealing

• Case outline
• In August, a malicious code were widely
  distributed and more than 300 Netbank accounts
  were stolen.
• The suspect intruded into a website and put
  malicious code on the main webpage.
• When users browsing the website, the malicious
  code will be installed automatically onto the
  users hosts.
• The malicious code will steal all kind of Netbank
  accounts and post onto another website hacked by
  the suspect.
• However
• The suspect know nothing about hacking
  technology.
• The suspect bought the malicious code and victim
  websites totally from other hackers.
• The suspect only working step by step according
  to the manual provided by other hackers.

12
Hacking cases WHY?
13
Hacking cases WHERE?How did they connected to
Internet?
Mobile/Wireless crime increased at the same time.
14
Hacking cases TARGET?

• Personal computers become the major part of
  victim in computer crime in recent year.

15
Preference of hackers
Damage to Internet Security
Small damage Less profit. (Newbie) Severe damage Less profit. ( Exploit buyer)
Small Damage More Profit (Experienced hacker) Severe damage More profit. (Almost none)
Profit
16
Why did they become criminal?

• They think
• Its not a crime, its just a game.
• A lot of people do it on Internet, so I can do
  it.
• I know its a crime, but I need money.
• I can hide myself very well.
• No one will investigate it.

17
What we learn from these data

• Computer crime and traditional crime are
  intermingle with each other.
• XSS vulnerability with phishing
• DDOS/IRC botnet with extortion
• Current protection technology have not
  successfully protect against following attack
  yet.
• Sql injection
• XSS
• Distribute malware over P2P/IM network
• Social engineering

18
What we learn from these data

• Those who dont know a lot of technology cause
  most of the damage to Internet directly.
• Their major aim is to make profit by stealing
  identity, Netbank account, online stock account,
  online game account etc.
• Most of them dont realized that there activity
  cause severe damage to Internet security.

19
What we learn from these data

• Exploit/Malicious code seller is one of the most
  big threat to cyber security.
• Investigation of exploit and malicious code
  should be emphasized by cyber police.
• Personal computer is becoming the major target of
  computer crime.
• Antivirus software will play a more important
  role in cyber protection.

20
How can anti-virus industry help cyber police?

• Report to police authority before publishing the
  detail information about the malcode/virus
• We have investigate the source of several virus
  this year.
• However, the detail information about the virus
  were published and the suspect never access the
  related network resource anymore.
• If you reporting to us beforehand, the source of
  most identity stealing malicious code can be
  revealed.

21
How can anti-virus industry help cyber police?

• Save the trail of virus.
• When we try to investigate a Botnet in 2003, we
  try to trace the source of the malicious code.
• However, malicious codes on a lot of victim hosts
  were killed by the anti-virus software.
• For example, save the following information
• Time stamp
• Hash value.
• Etc.

22
How can anti-virus industry help cyber police?

• Compare the character of different kinds of virus
  in order to find out the virus produced by the
  same author.
• A criminal is not grown up in one day.
• They always create more than one kind of virus.

23
How can anti-virus industry help cyber police.

• Integrate basic forensic analysis function into
  antivirus software.
• For example, extract the automatic running
  program list, there time stamp and hash value.
• When the user report an incident to anti-virus
  company, you will get more chance to collect the
  malicious code.
• Integrate antivirus technology into popular P2P,
  IM, Email and WEB server.
• Just kill the malicious code on personal computer
  fail to throttle the spread of malicious code.
• The malicious code distributed through P2P, IM,
  Email and WEB server can hardly be monitored and
  throttled.

Game Over

• Bye bye!
