Cyberthreats by Malware

1. 00:00Welcome to our new openHPI
2. 00:04course about Cyber Security and in this course we want to speak
3. 00:08about cyber threats by malware
4. 00:11and this is an ever growing threat which we can observe when
5. 00:16we speak about cyber security.
6. 00:19Over the intervening years we have an enormous growth in malware attacks, this is
7. 00:28malicious software.
8. 00:33So, alone in twenty twenty
9. 00:35pushed by the Corona-crisis, malware was targeting various -
10. 00:42in particular work from home software solutions.
11. 00:46In many cases people start with such work from home as solutions,
12. 00:53unprepared, it was during the lockdown, it was decided to
13. 01:00let people work from home and so a lot of solutions were
14. 01:07vulnerable and by means of cyberattacks, in particular by means of
15. 01:12attacks with malware, they could be
16. 01:15attacked.
17. 01:17So here is a chart which shows the number
18. 01:21malware variants attacking the Microsoft 365
19. 01:28software, this is the office software, and here we see
20. 01:33it's more than three million different malware variants
21. 01:38which were designed and which were used to attack systems only
22. 01:46to attack the Microsoft
23. 01:48365 suite or here is another
24. 01:53chart which shows the number of malware variants targeting mobile devices,
25. 02:01also more than one million.
26. 02:04If we look at the situation, here we have our internet.
27. 02:10Internet you remember is a network of networks and in the internet there is a
28. 02:16big number of services that are provided to the user. And the user
29. 02:23uses services by connecting to the internet
30. 02:29by different devices with their computers, with their laptops,
31. 02:33with their smartphone or tablets. So they are using hardware.
32. 02:39In the hardware there is an operation system which allows
33. 02:43to run several types of applications.
34. 02:46And the attack by means of malware from the side of attacker is
35. 02:53direct as well to the hardware as well to the operating system as to the
36. 03:00various applications.
37. 03:02And this is also a very important attack vector, the
38. 03:08cyber criminals attack immediately the user itself. This is
39. 03:14what we call the human factor and human engineering.
40. 03:19So malware is a central attack vector in cyberspace.
41. 03:26And we have to think and we have to learn about it because such malicious software
42. 03:33is a central weapon of cybercriminals.
43. 03:41Any device can be targeted by malware.
44. 03:45Malware can target the users as well as the providers, the service providers.
45. 03:52So home computers could be targeted, smart phones,
46. 03:58IoT - Internet of Things devices such as lamps, fridges, servers
47. 04:04and websites in the internet.
48. 04:07And malware makes it especially easy for the cybercriminals
49. 04:12to attack computer systems and users to break into the systems
50. 04:17to falsify data, to steal the data
51. 04:21to force the user to do something which gives the cyber attackers financial advantage
52. 04:29or others. So in this openHPI course, cyberthreats by malware, we
53. 04:38want to consider this topic in more detail.
54. 04:42So in the first wake now we start and will provide you general information about malware
55. 04:50attacks. Why is internet an interesting target for malware attacks,
56. 04:56who are the attackers on the internet, how does one get infected by malware -
57. 05:02these are topics we discuss in the first week. And then we finish with an excursus
58. 05:08on Advanced Persistence Threats. These are the most dangerous and complex
59. 05:16attacks which of course use malware components in different situations.
60. 05:23And then in the second week we will have a closer look on the
61. 05:26different kinds of malware. We will discuss viruses, worms, trojans,
62. 05:32we will discuss ransomware and scareware.
63. 05:36And this is of course very important - we want to discuss protective measures
64. 05:42against malware. And then we also provide excurses on firewalls and anti-virus software
65. 05:50to explain how these protection
66. 05:57systems are working.
67. 06:00My name is Christoph Meinel.
68. 06:03I'm the Head of the Hasso Plattner Institute and the Dean.
69. 06:07I have the chair of "Internet Technologies and Systems" and have a
70. 06:13very powerful research group working on that. And in our chair
71. 06:19we are working on security engineering, on cybersecurity - how to protect systems,
72. 06:25but we also speak about learning and knowledge engineering, digital education
73. 06:30and innovation research. And in this coutrse I am supported by
74. 06:35my PhD students - by Daniel Köhler,
75. 06:39he is working on security engineering and network security,
76. 06:44and by Muhammad Ihsan Sukmana,
77. 06:48his topic is cloud computing, secure cloud computing, access control
78. 06:54and enterprise storage solutions.
79. 06:58So we would be pleased if you
80. 07:03cooperate with us, if you come to this course and
81. 07:07if you use the discussion forum to interact with the other learners
82. 07:12which are interested in this topic cyber threats by malware.
