Transcripts

Marc:

Hello everyone and welcome back to Byte Sized Security.

2

:

I'm your host, Marc David, and today

we have a special guest with us,

3

:

Savvy Sharma, a cybersecurity expert.

4

:

We're going to delve into the MGM Resorts

Attack, a cyber incident that has raised

5

:

serious concerns about data security

and organizational vulnerabilities.

6

:

Savvy, welcome to the show.

7

:

Carla: Thank you Marc.

8

:

It's a pleasure to be here.

9

:

Marc: Let's jump right in.

10

:

Can you give us an overview of what

happened in the MGM Resorts Attack?

11

:

Carla: Certainly.

12

:

The attack was allegedly initiated by a

criminal gang known as Scattered Spider.

13

:

They used social engineering tactics

to gain a foothold in MGM's network.

14

:

They were successful in duping the

helpdesk into resetting a high-value

15

:

user's multi-factor authentication,

which led to a near shutdown

16

:

of MGM Resorts International.

17

:

Marc: That's alarming.

18

:

How did the attackers escalate

their access within the network?

19

:

Carla: They exploited a common mistake

of password reuse and gathered additional

20

:

information from LinkedIn profiles.

21

:

They then configured an entirely

additional Identity Provider in

22

:

the Okta tenant using a feature

called "inbound federation."

23

:

This gave them control not only

over Okta but also over MGM's

24

:

Microsoft Azure cloud environment.

25

:

Marc: What was the impact of gaining

control over these platforms?

26

:

Carla: It was catastrophic.

27

:

They deployed BlackCat/ALPHV

ransomware, which encrypted several

28

:

hundred of MGM's ESXi servers.

29

:

This led to a cascade of failures,

affecting hotel room keys,

30

:

dinner reservation systems,

point-of-sale systems, and more.

31

:

MGM was losing as much as $8.4

million in revenue every day

32

:

until the problems were fixed.

33

:

Marc: Can you elaborate on the role of

BlackCat/ALPHV ransomware in this attack?

34

:

Carla: Certainly.

35

:

BlackCat/ALPHV is part of

a Ransomware-as-a-Service

36

:

(RaaS) business model.

37

:

They provide professional services

that Scattered Spider lacks, such as

38

:

malware creation, back-end command and

control, and even negotiation services.

39

:

This collaboration amplified the

impact of the attack, causing cascading

40

:

chaos across MGM's operations.

41

:

Marc: That's a staggering amount.

42

:

What could have been done to prevent this?

43

:

Carla: One of the key chokepoints

was the MFA device reset.

44

:

If that had been detected or not possible,

the attack could have been limited.

45

:

Also, IAM infrastructure should be

considered Tier 0 assets, and their

46

:

compromise could lead to a significant

portion of a network being paralyzed.

47

:

Marc: What are some of the lessons

learned and mitigation strategies

48

:

that organizations can adopt?

49

:

Carla: Firstly, minimizing exposure

of privileged accounts is vital.

50

:

Implementing privileged access management

(PAM) solutions can reduce the risk.

51

:

Secondly, improving MFA control

by creating visibility into MFA

52

:

device changes is essential.

53

:

Lastly, protecting Tier 0 assets

and adopting Identity Provider

54

:

(IdP) best practices can go a long

way in securing an organization.

55

:

Marc: Could you share some of the

critical initial takeaways from

56

:

CyberArk Labs regarding this attack?

57

:

Carla: Absolutely.

58

:

Attacking IAM platforms is a common

tactic that threat actors use.

59

:

It gives them persistent access to an

organization and extends their privileges

60

:

into more systems, causing more damage.

61

:

The worst part of this breach was

that MGM’s IdP was configured in a

62

:

way that allowed Scattered Spider to

pivot into their VMware infrastructure.

63

:

This is where BlackCat/ALPHV

became involved.

64

:

Marc: Those are invaluable insights Savvy.

65

:

Before we wrap up, any final thoughts?

66

:

Carla: A series of mistakes ultimately

led to one of the most visible and

67

:

brand-damaging attacks in years.

68

:

To mitigate similar attacks, organizations

should focus on minimizing the exposure

69

:

of privileged accounts, implementing

strong authentication measures such

70

:

as MFA, protecting Tier 0 assets,

monitoring trust changes, and staying

71

:

updated on evolving cyber threats.

72

:

It’s a lot to do, but it’s crucial

for organizations to continuously

73

:

improve their security measures and

follow best practices to protect

74

:

themselves in today’s digital landscape.

75

:

Marc: Absolutely.

76

:

Savvy, thank you for joining us

today and sharing your expertise.

77

:

Carla: It was my pleasure Marc.

78

:

Thank you for having me.

79

:

Marc: And to our listeners, thank

you for tuning in to another

80

:

episode of Byte Sized Security.

81

:

Stay safe and stay informed.
