Closing the Gap: Threat Emulation

Agenda

1 The contemporary world of exploits

2 Introduction to threat emulation

3 Check Point Threat Emulation Solution

4 Summary

Exploits are here to stay

Number of critical exploits which allow the attacker to execute arbitrary code, published in 2011 alone

– 5 JRE exploits– 10 Chrome exploits– 26 Office exploits– 27 Internet Explorer exploits– 60 Firefox exploits– 48 Acrobat reader exploits– 56 Flash player exploits

On average, every 1.5 days– Previously unknown (and thus, unprotected against) exploit is published– Targeting software installed virtually on every PC

We have no reason to believe that the upcoming years will be different

Source: www.cvedetails.com

Anyone with decent technical capabilities who knows about the exploit before it is published, have a ‘zero-day’ attack which can be used in order to run arbitrary code on your network.

Signature based tools are not enough

IPS/ Anti Virus work by – Looking into specific patterns– Enforce compliance of protocols to standards– Detect variations from the protocols

They are limited in protecting from:

Unknown (zero day) attacks

Attack variations / obfuscated attacks

An updated IPS is a very good tool against known attacks and some of the unknown attacks.

Not enough to protect from unknown attacks.

– We need a different approach!

Attack obfuscation is a commodity nowadays; for example, at styx-crypt.com you can create an obfuscated version of a

malicious PDF for 25$ per file, quantity discounts apply

Another example – the Zeus malware isn’t sold directly. A ‘Zeus Builder’ is sold,

allowing to generate another malware variant in a click

CVE-2008-2641 as an example

JavaScript vulnerability in Acrobat Reader

Heap Spray attack – Java Script code which ‘fills’ the heap with shell code, and allows arbitrary code execution when Acrobat ‘crashes into it’

How can you sign it?– There are infinite ways to implement the attack (using

recursion, loops, whiles, divisions to functions, etc.)– Writing code that understand code (without running it) is hard– PDF document can contain sections which are

encoded/compressed in various algorithms– Engines must be constantly updated to support new acrobat

features.

Actual code that performs get to fdf.p-.kkk.xgx78i6p6rlv0.

Bottom line:

Signature based tools are not enough against advanced attacks

Gartner, Aug 2011 - Strategies for Dealing With APT - Quotes

“Through year-end 2015, financially motivated attacks will continue to be the source of more than 70% of the most damaging cyberthreats”

“…these are not noisy, mass attacks that are easily handled by simple, signature-dependent security approaches.”

“Targeted attacks often use custom-created executables that are rarely detected by signature based techniques”

“Gartner estimates that, for the average enterprise, 4% to 8% of executables that pass through antivirus and other defenses are malicious”

Key Finding – “Simply adding more layers of defense does not necessarily increase security against targeted threats — security controls need to evolve”

Email with malicious

attachment

Threat emulation – malicious attachment example

Email with malicious

attachmentExtracting attachments

Emulation

During the emulation, the attachment is opened on several emulated machines – from XP to Windows 7, and the entire system activity is monitored for unexpected behavior. We monitor network activity, file system & registry changes, process activity and more.

Malware detected

We know what should happen on the machines when opening a legitimate document (‘White List’), thus we can safely consider any document which causes the machine to do something else as malicious.

High performance – supports up to 100,000 unique files per day

Support Check Point provided OS images and custom images

Emulation of documents and executable files

Deep inspection of the system – file system, API calls, network, registry, memory and more.

Anti-VM detection capabilities

Pre-Emulation Static Filtering

Contemporary documents range from very simple to ultra complex

Usually, the risk factor of a document varies according to the number of advanced feature it utilize–E.g. JavaScript support in Acrobat reader

The pre-emulation static filtering process allows skipping documents which contains only safe features

– Filters are constantly updated

Filters ~70 – 80% of the documents

Granular Policy

Anti Bot & Anti Virus Rule base now includes also Threat Emulation

Threat Emulation profile controls the emulation configuration:

Where to emulate – Locally, other gateway or cloud

How – which images to use, use static analysis, …

Threat Emulation allows you to define not only the inspected machines (via IPs of machines to scan),

but also scope according to email address.

Integrated with identity awareness to match the right profile according to the user identity

Encrypted traffic support

Just because traffic is encrypted doesn’t mean the file transferred isn’t malicious

Integration with Check Point SSL Inspection– Visibility into encrypted web traffic

Integration with Microsoft Exchange– Allowing visibility to SMTP over TLS– Using a dedicated Agent

The DDoS phenomenon

Increasing numbers of organizations are affected by massive amounts of traffic

What is an DoS Attack?

Denial-of-Service attack (DoS attack) an attempt to make a machine or network

resource unavailable to its intended users.

Distributed Denial-of-service attack (DDoS) is coordinated and simultaneously launched

from multiple sources

DoS attackers can be segmented into three

categories:

Motivations behind (D)DoS attacks?

Hacktivists

Their motive, make social and political points Primarily through public IT disruption. “Use of legal and/or illegal digital tools in

pursuit of political ends".

Nation State Driven

Presumably sanctioned by governments. Reasons, disrupting governmental operations. Stealing national secrets.

Financially Motivated Attackers

DoS attacks are merely a diversion The actual objective is to steal information Lately instances of DoS "ransom attacks"

Cybercrime Trends for 2012

SQLInjections

Botnet

Ponemon Institute, May 2012

65% of Businesses Experienced Attacks

Average $214,000 of Damage Per Attack

DDoS ‘as a Service’

Pay per hour, no expertise needed!

Victims of Recent DDoS Attacks

“DDos-attacker är nästan omöjliga att värja sig

emot” — SVD “Overload attacks are almost impossible

to protect against.” — SVT

DDoS Attack Examples

Volumetric Attacks – Fill the pipe

DNS Amplification Attacks– Using critical applications

as attack source

SYN Attacks– Simple way to use

resources

Application Attack – Renegotiate SSL Key– Slow HTTP Post– DNS Query flood

Application Layer DDoS Attacks

Exploit application weakness with Low&Slow attacks

Undetectable by threshold ‒ or volume-based solutions

New Application Attacks Are Stealthier…

Utilize relatively low volume and fewer connections

Used in conjunction with volume-based attacks

Real World of Real Attacks

US Banking attacks – Volumetric

– Application

– Continues and Dynamic

DNSSEC Attack Example– Ability to execute DDoS

Amplification attack via US Gov

Application low and slow attack– Lets hold those HTTP connections open forever

– Very hard to find

DDoS and Traditional Security

Attackers Take Advantage of Traditional Security

Firewalls track state of network connections (Can be bottleneck)

Firewalls allow legitimate traffic (e.g. port 80 to web server)

IPS allows legitimate request (e.g. get http/1.0\r\n)

Application Control allows legitimate services (DNS or HTTP)

Traditional Firewalls Not Sufficient

Not Designed for Network and Application DDoS Protection

Basic rate based flood protection affects all traffic (Real users and attack traffic)

Lacks Comprehensive Layer 7 DDoS protection

– Poor detection of sneaky attacks

– No filters to block attacks and allow real traffic

– Administrators cannot create custom signatures
