00:00:00.000 --> 00:00:01.290
In this lesson,

2
00:00:01.290 --> 00:00:04.620
we will learn about Electromagnetic Attacks.

3
00:00:04.620 --> 00:00:08.910
Electromagnetic attacks use electromagnetic interference,

4
00:00:08.910 --> 00:00:13.320
or EMI, or electromagnetic pulses, or EMP,

5
00:00:13.320 --> 00:00:17.610
to disrupt, damaged, or manipulate hardware and data.

6
00:00:17.610 --> 00:00:20.610
EMI attacks involve the deliberate emission

7
00:00:20.610 --> 00:00:22.680
of electromagnetic signals

8
00:00:22.680 --> 00:00:25.530
that can interfere with the normal operation

9
00:00:25.530 --> 00:00:27.540
of electronic devices.

10
00:00:27.540 --> 00:00:29.610
An EMP on the other hand,

11
00:00:29.610 --> 00:00:33.030
is a powerful burst of electromagnetic energy,

12
00:00:33.030 --> 00:00:36.300
often generated by specialized devices

13
00:00:36.300 --> 00:00:38.820
that can damage or permanently disable

14
00:00:38.820 --> 00:00:41.160
electronic circuits and components

15
00:00:41.160 --> 00:00:44.970
by overwhelming them with a sudden surge of energy.

16
00:00:44.970 --> 00:00:48.420
Let's learn more about electromagnetic interference

17
00:00:48.420 --> 00:00:51.360
and electromagnetic pulse attacks.

18
00:00:51.360 --> 00:00:54.390
First, we have electromagnetic interference,

19
00:00:54.390 --> 00:00:56.445
or EMI, attacks.

20
00:00:56.445 --> 00:00:59.400
EMI attacks are malicious activities

21
00:00:59.400 --> 00:01:02.640
where attackers generate electromagnetic signals

22
00:01:02.640 --> 00:01:07.640
to disrupt or influence the operation of electronic devices.

23
00:01:07.650 --> 00:01:10.320
These attacks work by introducing

24
00:01:10.320 --> 00:01:13.770
external electromagnetic noise or signals

25
00:01:13.770 --> 00:01:16.380
that interfere with the normal functioning

26
00:01:16.380 --> 00:01:18.810
of the target device's circuits.

27
00:01:18.810 --> 00:01:21.000
By carefully tuning these signals,

28
00:01:21.000 --> 00:01:23.700
attackers can cause temporary glitches,

29
00:01:23.700 --> 00:01:27.570
data errors, or even induce faults in devices,

30
00:01:27.570 --> 00:01:32.130
which can lead to disrupted operations or compromised data.

31
00:01:32.130 --> 00:01:34.680
EMI attacks are particularly dangerous

32
00:01:34.680 --> 00:01:37.470
because they don't require physical access

33
00:01:37.470 --> 00:01:41.490
or immediate proximity to the device that is being attacked.

34
00:01:41.490 --> 00:01:43.770
You might think of an EMI attack

35
00:01:43.770 --> 00:01:45.720
like trying to listen to someone

36
00:01:45.720 --> 00:01:49.020
in a room full of loud overlapping voices.

37
00:01:49.020 --> 00:01:52.980
In this room, the interference, which are the voices,

38
00:01:52.980 --> 00:01:55.410
drowns out the intended message,

39
00:01:55.410 --> 00:01:59.310
just as EMI distorts or disrupts the signals

40
00:01:59.310 --> 00:02:01.230
to target a device.

41
00:02:01.230 --> 00:02:04.110
An example of a malicious EMI attack

42
00:02:04.110 --> 00:02:06.870
may involve disrupting a medical device,

43
00:02:06.870 --> 00:02:09.450
like a pacemaker or insulin pump.

44
00:02:09.450 --> 00:02:12.750
By generating a strong electromagnetic field

45
00:02:12.750 --> 00:02:13.920
near the device,

46
00:02:13.920 --> 00:02:17.250
an attacker could interfere with its normal operation,

47
00:02:17.250 --> 00:02:19.770
potentially causing it to malfunction.

48
00:02:19.770 --> 00:02:24.270
In other cases, EMI attacks could target computing devices,

49
00:02:24.270 --> 00:02:27.390
inducing faults in CPUs or memory

50
00:02:27.390 --> 00:02:31.050
to cause data corruption or system crashes.

51
00:02:31.050 --> 00:02:34.020
So to protect against EMI attacks,

52
00:02:34.020 --> 00:02:38.370
organizations should consider shielding sensitive devices

53
00:02:38.370 --> 00:02:41.040
with materials that block or absorb

54
00:02:41.040 --> 00:02:43.200
electromagnetic interference,

55
00:02:43.200 --> 00:02:46.620
such as copper or aluminum enclosures.

56
00:02:46.620 --> 00:02:50.940
Additionally, setting up secure shielded rooms or zones

57
00:02:50.940 --> 00:02:52.290
for critical equipment

58
00:02:52.290 --> 00:02:56.700
can help isolate them from external electromagnetic sources.

59
00:02:56.700 --> 00:03:00.120
Finally, regular testing for EMI resilience

60
00:03:00.120 --> 00:03:04.680
and adherence to EMI standards, such as FCC guidelines,

61
00:03:04.680 --> 00:03:06.870
can also help organizations

62
00:03:06.870 --> 00:03:09.600
identify and address vulnerabilities

63
00:03:09.600 --> 00:03:13.470
in devices that may be susceptible to EMI.

64
00:03:13.470 --> 00:03:18.470
Second, we have electromagnetic pulse, or EMP, attacks.

65
00:03:18.510 --> 00:03:21.660
EMP attacks involve the generation

66
00:03:21.660 --> 00:03:25.860
of a sudden powerful burst of electromagnetic energy

67
00:03:25.860 --> 00:03:29.850
to disable or destroy electronic devices.

68
00:03:29.850 --> 00:03:34.290
EMPs are intense and brief, causing voltage surges

69
00:03:34.290 --> 00:03:37.860
that can overwhelm the circuits of electronic equipment,

70
00:03:37.860 --> 00:03:41.190
leading to permanent damage or system failure.

71
00:03:41.190 --> 00:03:43.050
Unlike EMI attacks,

72
00:03:43.050 --> 00:03:46.410
which aim to interfere with normal operations,

73
00:03:46.410 --> 00:03:49.110
EMP attacks are usually intended

74
00:03:49.110 --> 00:03:52.890
to completely incapacitate targeted devices.

75
00:03:52.890 --> 00:03:56.550
Think of an EMP like an electronic tidal wave

76
00:03:56.550 --> 00:03:59.190
that sweeps through anything in its way

77
00:03:59.190 --> 00:04:02.370
instantly overwhelming everything in its path

78
00:04:02.370 --> 00:04:05.790
and leaving electronics unable to function.

79
00:04:05.790 --> 00:04:08.160
An EMP attack could involve

80
00:04:08.160 --> 00:04:11.130
disabling a building's network infrastructure,

81
00:04:11.130 --> 00:04:15.660
like servers or routers, with a high energy EMP device.

82
00:04:15.660 --> 00:04:19.440
When targeted, the EMP would produce a voltage spike

83
00:04:19.440 --> 00:04:21.450
across the device's circuits

84
00:04:21.450 --> 00:04:23.730
burning out essential components

85
00:04:23.730 --> 00:04:26.730
and effectively disabling the network.

86
00:04:26.730 --> 00:04:29.220
This could be especially damaging

87
00:04:29.220 --> 00:04:31.800
in critical infrastructure environments,

88
00:04:31.800 --> 00:04:34.350
such as hospitals or power plants,

89
00:04:34.350 --> 00:04:36.870
where disruption of electronic systems

90
00:04:36.870 --> 00:04:40.590
can lead to serious life-threatening consequences.

91
00:04:40.590 --> 00:04:45.480
Devices like EMP generators or directed-energy weapons

92
00:04:45.480 --> 00:04:49.950
are capable of producing such electromagnetic pulses.

93
00:04:49.950 --> 00:04:53.220
So to mitigate the risk of EMP attack,

94
00:04:53.220 --> 00:04:56.610
critical systems can be protected with Faraday cages,

95
00:04:56.610 --> 00:04:59.760
which are enclosures made of conductive materials

96
00:04:59.760 --> 00:05:03.660
that can block or absorb electromagnetic pulses.

97
00:05:03.660 --> 00:05:06.990
Surge protectors and power conditioning devices

98
00:05:06.990 --> 00:05:11.220
can also help by regulating unexpected voltage spikes.

99
00:05:11.220 --> 00:05:14.820
Additionally, ensuring critical infrastructure systems

100
00:05:14.820 --> 00:05:19.740
are resilient to EMPs by following EMP protection standards,

101
00:05:19.740 --> 00:05:24.000
such as MIL-STD 188-125,

102
00:05:24.000 --> 00:05:27.720
can help organizations prepare for and prevent

103
00:05:27.720 --> 00:05:32.040
potential damages from these high energy attacks.

104
00:05:32.040 --> 00:05:35.730
So remember, electromagnetic attacks

105
00:05:35.730 --> 00:05:39.300
use electromagnetic interference, or EMI,

106
00:05:39.300 --> 00:05:44.300
or electromagnetic pulses, or EMP, to disrupt, damage,

107
00:05:44.310 --> 00:05:48.480
or manipulate electronic devices and data.

108
00:05:48.480 --> 00:05:52.650
EMI attacks work by emitting electromagnetic signals

109
00:05:52.650 --> 00:05:56.250
that interfere with a device's normal operations,

110
00:05:56.250 --> 00:05:59.280
often causing glitches or data errors

111
00:05:59.280 --> 00:06:01.110
without direct contact.

112
00:06:01.110 --> 00:06:03.540
EMP attacks, on the other hand,

113
00:06:03.540 --> 00:06:07.500
involve a powerful surge of electromagnetic energy

114
00:06:07.500 --> 00:06:10.650
that can permanently damage electronic circuits

115
00:06:10.650 --> 00:06:14.670
by overwhelming them with an intense energy spike.

116
00:06:14.670 --> 00:06:19.350
In other words, EMI attacks focus on disrupting operations,

117
00:06:19.350 --> 00:06:21.600
while EMP attacks are designed

118
00:06:21.600 --> 00:06:25.860
to completely disable or destroy targeted devices.

119
00:06:25.860 --> 00:06:28.350
So to protect against these threats,

120
00:06:28.350 --> 00:06:31.140
organizations can use shielding techniques

121
00:06:31.140 --> 00:06:34.440
and other protective measures, like a Faraday cage,

122
00:06:34.440 --> 00:06:38.010
to prevent interference and ensure system resilience

123
00:06:38.010 --> 00:06:41.073
against electromagnetic disruption.
