Quarterly Update

with Steve Spano

“At its core, CIS is about sharing information.” I want to welcome you to the first edition of CIS’ newest product, Cybersecurity Quarterly. As the President and COO of CIS, I am proud and humbled to add “editor” to my resume. There are many things that CIS does, from the MSISAC, which is the go-to resource for cyber threat prevention, protection, response, and recovery for state, local, tribal and territorial government entities, to the CIS Controls and CIS Benchmarks, which are recognized best practices for securing IT systems. At its core though, CIS is about sharing information. Cybersecurity Quarterly has been developed to share information on the quarter that has been and to take a moment to highlight what may be coming down the path. The funding to develop this publication comes from our vendor partners in the CIS CyberMarket program (formerly the Trusted Purchasing Alliance), who not only support CIS, but also support our nation’s state and local governments by discounting their products and services. These partnerships have saved our participating organizations over $40 million in the last 4 years, and we forecast that number to continue to grow as we add more vendors in the years to come. We truly value our vendor partners, and I invite you to consider them in your future procurement decisions. I ask that you consider speaking with a member of our staff regarding our current vendor partners, and welcome you to provide suggestions for great products and solutions that we may secure discounts with in the future. The staff who run this program can be reached at info@cisalliance.org and are always looking for new ways they can help your

organization obtain the cybersecurity solutions it needs, at a price it can afford. Finally, I ask that you take some time out of your busy schedule to review this publication, as in the hectic world we live in, it is easy to lose sight of the forest when we are putting out so many fires. If we do not take a moment to look around though, we may miss the fact that the tools we need are within our grasp. I will be keeping this column as a way to share a selection of my thoughts on cybersecurity, procurement, and other challenges we all face in finding these tools. As I have worked in and around government for my entire career, I can assure you that I have some opinions! Please do not hesitate to share your thoughts on this newest addition to the family of CIS products. Thank you for being a valued partner in this journey we are all on together.

Why Inventory Matters for Security One of the first and most important steps in securing your organization’s network — determining what devices are actually connected to it By Philippe Langlois As many organizations are chasing down the “best threat feed” and scrambling to find the tools with the most “machine learning capabilities,” they sometimes neglect some of the foundational security controls that every organization should master. At CIS, we are firm believers that organizations must have an intimate knowledge of their infrastructure to know what to protect and how best to protect it. Consider it a form of “defensive intelligence” that focuses on internal knowledge of assets and vulnerabilities, instead of “threat intelligence” that focuses on adversaries. We realize that not every organization has the resources to stand up their own intelligence team and translate threat intel reports into defensives actions; that is why we’ve imbued our knowledge of adversaries and cyber defense into the CIS Critical Security Controls, a set of prioritized cybersecurity recommendations used by organizations worldwide to counter the most pervasive cybersecurity attacks. There are currently 20 CIS Controls, each of which is further divided into sub-controls. The CIS Controls provide the ultimate end-state organizations should seek to achieve as part of their cybersecurity efforts, while the sub-controls provide prescriptive actions organizations can take to achieve the goals. The CIS Controls cover many of the traditional areas of

In a world of clouds, mobile devices, BYOD, and so on, why does it matter to protect hardware? ... because data still resides somewhere, and we still have a duty to protect the confidentiality, integrity, and availability of that data. cybersecurity, such as vulnerability management (Control 4) and malware defense (Control 8), as well as objectives that are often considered to be IT management activities. In this article, we’ll examine the importance of managing your hardware and software through CIS Control 1: Inventory of Authorized and Unauthorized Devices. In a world of clouds, mobile devices, BYOD, and so on, why does it matter to protect hardware? ... because data still resides somewhere, and we still have a duty to protect the confidentiality, integrity, and availability of that data. Therefore, we better know what is in our environment and how it is being stored, processed, and accessed. Your inventory of hardware assets should include not just a static list of assets, but also the ability to automatically detect new assets being connected to your environment, as

well as the ability to deny those unapproved devices. There are two main reasons why you should care about maintaining an accurate inventory of hardware on your network. The first is the more classical justification in security: “I want to detect and correct when bad guys walk in and plug something into my infrastructure.” It might sound rather far-fetched to think that someone could just simply walk into your organization and plug in a device, but this has become a common part of many pentests for a reason – it works! Of course, you would hope that staff would be a little wary of an unknown and unaccounted device suddenly showing up, but what if that computer was just a small Raspberry Pi hidden in a universal power supply? If you haven’t heard of the companies that now produce pentesting tools masquerading as normal office technology, fire up your favorite browser and learn all the creative places people have stuffed their favorite pentesting operating system. Neat stuff for a pen tester; a little more harrowing from a defender’s perspective. The second reason an accurate hardware inventory matters: how can you protect something if you don’t know it’s there? In order to properly scan, fix, and secure all your assets, you need to have an accurate count of them. We’ve seen it happen all too often where a scanner was misconfigured or a single device was forgotten, leaving the door open for cyber criminals to wreak havoc. One of the classic

Inventories can get complicated and it may not seem like a high pay off at first, but without knowing what to protect and how to keep rogue devices off your network, you’ll have a difficult time applying the other Controls and protecting your organization. stories about forgotten assets is the case of the university that was unable to find one of their server racks, only to discover, after physically following the Ethernet cable, that it had been walled over! Inventories can get complicated and it may not seem like a high pay off at first, but without knowing what to protect and how to keep rogue devices off your network, you’ll have a difficult time applying the other Controls and protecting your organization. Don’t let your forgotten assets be an easy target!

Threat of the Quarter This Quarter’s Threat: Business Email Compromise Scams What is it? Companies and U.S. state, local, tribal, and territorial (SLTT) governments are frequently targeted by Business Email Compromise (BEC) scams that attempt to deceive recipients into sending money or employees’ personally identifiable information (PII), or that use the entity’s name to fraudulently obtain material goods. Successful attacks are highly likely to result in financial fraud or identity theft, and it is possible they will result in compromises or data breaches. The Multi-State Information Sharing and Analysis Center (MS-ISAC) has identified three variants as routinely targeting or effecting SLTT governments. These variants are also widely reported as targeting private companies around the globe. All three originate from compromised, spoofed, or fraudulent email accounts, which are used to issue the request, and all three are associated with significant data or financial loss. Purchase Order Fraud Variant: In this variant, cybercriminals obtain publicly available purchase order forms, and change the contact details on the forms to include different telephone numbers and email addresses or copycat websites. They then submit the purchase order to a vendor, have the goods shipped to a new address (often a mule, another victim, or directly overseas), and sell them for profit while the bill goes to the affected entity. W-2 and PII Data Theft Variant: In this variant, cybercriminals pose as an administrator or senior official and send a targeted email to the human resources or finance departments requesting an email with all employees’ W-2 information or PII. The MS-ISAC believes W-2 information and PII stolen in this manner are often used to commit tax fraud and

identity theft. Ransomware vs. BEC Ransomware infections often receive more press coverage, although BEC scams can be more costly. In 2016, ransomware attacks were estimated to cost organizations $1 billion, while BEC scams have resulted in over $5 billion stolen since 2013, according to the Internet Crime Complaint Center (IC3). According to NTTSecurity, the average cost of a ransomware attack to an organization is $700, while the average cost of a BEC scam is $67,000.

Financial Theft Variant: In this variant, cybercriminals pose as an employee or senior official and request immediate wire transfer or that “transactions” need to be “set up and processed.” The emails are typically directed toward the human resources or finance departments and convey a sense of urgency. In financial theft BEC emails, cybercriminals often use the name of the email target to establish trust and imply an existing relationship, which increases the likelihood of the target sending money to the cybercriminal. All variants of the BEC scam can involve compromising the email account of the senior official and using it to send the email request, rather than simply spoofing the account. When that occurs, the cybercriminal has full access to the account, and can setup auto forwarding or other rules, resulting in additional compromises. According to IC3, there are multiple variants of the scam which target businesses and governments. More information on how the IC3 defines the five variants is on the IC3 website.

Summer 2017

Recommendations Cybercriminals use traditional social engineering and phishing techniques to conduct BEC scams, which help increase the likelihood of successful attacks. Since the ultimate target of a BEC attack is the end-user, awareness of BEC scams and the indicators are key. The MS-ISAC recommends: Indicators of BEC spam emails can include: Information Technology (IT) staff should handle incidents where the user supplied their credentials as a potential data breach. Mitigation steps need to include changing the user’s password and ensuring that malicious actors did not login to the network and/or setup email rules. If malicious actors did login, IT staff should consider the incident as a possible breach until it can be determined if the malicious actors had network access and/or received information. Read and implement the recommendations from the MS-ISAC Spear Phishing Primer at https://www. cisecurity.org/white-papers/cis-primer-phishing. Craft a policy for identifying and responding to phishing emails and train staff to follow the policy. Make sure to include the following: When receiving unusual requests, users should verify the identity and authority of the email sender via standard (non-email) channels. The true recipient of an email can often be verified by hovering the mouse over the address in the email header. Users should “hover to discover,” ensuring that their email is going to the correct person. Users should reply by forwarding, and not by hitting the “reply” button, which helps to prevent successful spoofing attacks.

Poorly crafted emails with spelling and grammar mistakes, especially those indicating the email was sent from a mobile device (e.g. iPhone, iPad, Android, etc.) in order to convince the recipient the mistakes can be ignored. The email may include the wrong or an abbreviated signature line for the supposed sender. The email may use full names instead of nicknames (e.g. “Jennifer” instead of “Jen”) and the language structure may not match how the supposed sender normally communicates. The email specifies that the only way to contact the sender is through email. In some cases, the emails appear to be timed to correspond with times the senior official is out of the office. The transactions are for a new vendor or new contract. Internal warning banners to indicate the email is possibly spam, spoofed, or from an external source. Implement filters at your email gateway to filter out emails with known phishing attempt indicators and block suspicious IPs at your firewall. Flag emails from external sources with a warning banner.

Users should report suspicious emails to security staff. The MS-ISAC also appreciates receiving notifications of all BEC scam attempts.

Reach out and warn other departments and agencies of the BEC scam.

Train staff in the finance and human resources departments to identify potential BEC scam emails and follow the suspicious email policy.

Report BEC scams at https://bec.ic3.gov/. Taxrelated suspicious emails should be reported to the IRS at https://www.irs.gov.

Network Hide & Seek A white-hat hacker’s step-by-step guide to discovering hidden assets on your network using open source software and tactical strategy By Tyler Wrightson Want to understand your network environment like a cybercriminal might? You’ve come to the right place! Understanding your environment by identifying and creating an inventory of your devices is a foundational step in being able to secure your assets. After all, if you don’t know what you have, how can you be expected to secure it? We’re going to take a unique approach here and identify assets utilizing the same methods a would-be attacker might use. And you’re in luck — we’re going to take an extremely pragmatic and economical approach by only utilizing open source software.

I can’t tell you the number of times I’ve identified large ranges of network subnets which were unknown to our client. Consider this article the very first tactical step you can take in identifying assets. You’ll want to follow this up with additional steps to create a comprehensive inventory of the assets on your network. For the sake of brevity, in this article, we’ll focus on the following three major steps that you can take to identify what your network looks like and what currently resides on it:

Map your network at layer 3 (Active IP Subnets) Identify IP based assets on the network Identify general information of those assets (hostname, services, etc.) There is something to be said for identifying every single asset on your network; however, this is an extremely difficult goal to scale. For that reason, we’re going to focus on identifying the most meaningful data first, such as number of active subnets, network topology, and most important subnets (based on the types of assets on that subnet). I can’t tell you the number of times I’ve identified large ranges of network subnets which were unknown to our client. In a few cases, these were vendor networks connected via either a dedicated line or a VPN. In other cases, they were simply areas of the network that had been forgotten; we were wiping away the digital cobwebs, so to speak. To identify live subnets, my tool of choice is Masscan (https://github.com/robertdavidgraham/masscan). According to the Masscan website, Masscan is “the fastest Internet port scanner.” It can scan the entire

Summer 2017

Internet in under 6 minutes, transmitting 10 million packets per second.

The final argument is the network range to be scanned.

If masscan can scan the entire Internet in six minutes, it should have no problem on your network! That being said, a word of caution: if you try to utilize the maximum speed of masscan, you are almost guaranteed to cause problems on your network. To identify all live subnets, we’ll want to scan all RFC 1918 addresses. Note that you’ll also want to scan any public IP ranges that your company owns. The private IP ranges are:

The ports we chose here are common ports. If you know of unique ports that are likely to be in your environment, then you should include them in the list. The ‘rate’ argument is one of the most important, as it defines the Packets Per Second. At a rate of 1,000, you can expect to generate over 500 Kbit per second! This means that if you set the rate much higher, you can easily overload boundary links (such as firewalls).

10.0.0.0/8

In addition to scanning all of the private IP ranges, you’ll also want to scan any public IP ranges your organization owns. If all the subnets you identified are known to you, great! Proceed to Go and collect $200. If there are subnets you were previously unaware of, we’ll want to further understand what is on those subnets.

172.16.0.0/12 192.168.0.0/16 The command we’ll use is: masscan -oG 10.mass.txt -p21,22,23,25,53, 139,389,445,80,443,1433,1443,3389,8008,8080, --rate 1000 10.0.0.0/8 Here’s a breakdown of the arguments: -oG specifies the output file to save the results in (in grepable formant) -p specifies the ports to scan on each host --rate specifies the Packets Per Second (PPS)

Understanding the general makeup of the systems is relatively straightforward. We can make some assumptions based on the ports we find open and then get additional information based on those services. For example, if we see a host with port 139 (NBT),445(CIFS) and 3389(RDP) open, we can assume it’s a Windows system. We can then get more information about the specific system by connecting via RDP, or query its hostname via NetBIOS. Utilizing tools such as nbtscan, we can scan a subnet to obtain information about NetBIOS hostnames on target windows systems. The nbtscan tool is very straightforward to use. (continued on next page)

user@linux:~$ nbtscan 192.168.1.0/24 Doing NBT name scan for addresses from 192.168.1.0/24 IP address NetBIOS Name Server User MAC address -----------------------------------------------------------------------------192.168.1.35 Web1 <server> <unknown> d0:67:e5:40:0b:43 192.168.1.30 KBOX <server> KBOX 00:00:00:00:00:00 192.168.1.5 FileSrvr <server> FileSrvr 00:00:00:00:00:00 192.168.1.55 LSWINBOX <server> <unknown> 00:21:cc:65:d1:00 192.168.1.106 Laptop01 <server> <unknown> 10:0b:a9:74:39:3c 192.168.1.111 MF840-C02S94YLF <unknown> c4:b3:01:c3:71:67

In the example shown at the bottom of the previous page, you can see this appears to be a somewhat convoluted subnet. We have indications there could be servers (file and web), laptops, and a printer. Many times, understanding the general makeup of hosts and their hostnames is a great step in the right direction to identifying the purpose of those systems and the subnet.

Many times understanding the general makeup of hosts and their hostnames is a great step in the right direction to identifying the purpose of those systems and the subnet. Of course, the old standby of obtaining a banner with a tool, such as netcat (or telnet), if you are unsure of the service you’ve identified can be helpful as well. Many services will give a strong indication of what service is running simply by connecting with netcat. In the example below, you can see someone configured SSH to run on a nonstandard port (port 8080) and, by connecting with netcat, we immediately get a specific version of SSH. user@linux:~$ nc 192.168.1.5 8080 SSH-2.0-OpenSSH _ 7.2p2 Ubuntu-4ubuntu2.1 An additional tool that has proven to be extremely helpful is EyeWitness, which you can download from https://github.com/ChrisTruncer/ EyeWitness. EyeWitness allows you to take screenshots of websites that we specify. If you’ve identified many unknown systems with ports 80,443,8443,8008,8080, etc. open, you can specify those as the target file to EyeWitness and quickly get a screenshot of the web application running on that system. You might be surprised just how many forgotten web applications and systems can be found on your networks.

Protecting and Controlling Sensitive Government Information with IRM By Rick Comeau State, local, tribal and territorial (SLTT) governments continuously receive, process, and transmit vast amounts of sensitive, citizen-centric information. Personally identifying information (PII), compensation and tax data, court records, law enforcement information, driver records, protected health information, vital records—these are just some of the types of sensitive information SLTT governments must ensure are kept confidential and out of the hands of unauthorized individuals. SLTT government officials are entrusted by their constituents with keeping their private and sensitive information secure. There is no amount or level of public apologies, credit monitoring services, etc. that can repair the damage in public trust resulting from a breach of citizen PII or other private or financial data.

There is no amount or level of public apologies, credit monitoring services, etc. that can repair the damage in public trust resulting from a breach of citizen PII or other private or financial data. SLTT governments are in an especially challenging position when it comes to data breaches. They are responsible for securing more sensitive information than just about any other infrastructure sector. However, they face the same amount—if not more— cyber threats, both malicious and unintentional, as

many organizations in the private sector and at the federal government level. SLTT governments are also faced with insufficient budgetary resources and therefore must spend judiciously on cybersecurity controls that help achieve the greatest overall reduction in cyber risk. Cybersecurity decisions must also be made in a world where workforces are becoming increasingly mobile and citizens expect online government resources to be available from anywhere, at any time and on any device. With data breaches continuing to climb, SLTT government cybersecurity and IT professionals should consider the prospective return on security investment of an Information Rights Management (IRM) solution. IRM, also referred to as Digital Rights Management (DRM), is a security technology offering huge security benefits to organizations that must maintain protection and control over sensitive information externally shared with partner organizations (e.g. other states or local governments, federal agencies) and customers (citizens, businesses, etc.) IRM uses strong encryption and a complex—yet user-transparent— system of digital certificates and licenses to extend protection and control over files residing outside an organization’s network perimeter. An information owner leverages IRM technology to restrict file access to a specific recipient(s) wherever that file may be sent or saved, including a personal desktop or laptop computer, USB “thumb” drive, personal email account, or consumer grade cloud storage service. The content remains lifetime-protected by Advanced Encryption Standard (AES) encryption and is restricted to only authenticated and authorized

Summer 2017

user(s). Explicit usage rights or permissions (e.g. view only, view/print, view/print/edit) can also be set for IRM-protected files, and those permissions are enforced for the life of the file and wherever it may travel. An unauthorized user, no matter where he or she may have downloaded and saved an IRMprotected file, will simply not be able to break the strong encryption protecting the file contents and will be prevented from accessing the information.

IRM technology has actually been around for well over a decade; however, it has matured greatly over the last few years. IRM technology has actually been around for well over a decade; however, it has matured greatly over the last few years. One of the biggest, longstanding challenges had been making IRM work across independent organizations and users where each organization has its own mechanism for identity and access management. Potential solutions included letting external partners into an organization’s own user directory system; replicating an organization’s directory service in a network “demilitarized zone” (DMZ), where identities and access authorizations of external users could also be managed; and even establishing direct, trusted connections between partner organizations’ directory systems. However, all of these strategies have proven to be incredibly complex and costly to implement, difficult to manage and maintain, and loaded with security risks. And these challenges only increase as organizations seek to expand their IRM trust model to larger groups of external collaborators. Fortunately, there now exist mature, cloud-based IRM solutions that have overcome the previous challenges with making this game-changing, information-level security technology work across independent organizations and users. There are even cost-effective IRM capabilities that are natively available within intuitive secure collaboration platform solutions. However, not all IRM technologies are alike, and there are essential functions and features SLTT governments should look for in an IRM solution, including the following:

Intuitive and easy to use – applying IRM protection to a file should be readily apparent and easy to do (“click of a button”). Plug-in free/agentless – an authorized external party whom receives an IRM-protected file should not have to install a browser plug-in or software agent (or wait on their IT administrator to do so) in order to access and use the file. Dynamic policy updates – an information owner should be able to dynamically change user permissions, as well as eliminate (“unshare”) access/ use rights, to IRM-protected files if and when necessary. The benefits of IRM technology arr likely still unknown to many SLTT government IT and cybersecurity personnel, but it offers a promising solution that could greatly enhance the security of sensitive, often citizen-owned or identifying, information. SLTT government mission activities will continue to require the constant exchange of sensitive information with the people and businesses within their jurisdictions, as well as other public and private sector entities. IRM solutions would provide the necessary assurance for SLTT governments to continue providing their vital, information-intensive services in the face of targeted data exfiltration attacks, malicious insiders, and even unintentional data exposures. IRM protection would also boost citizen confidence that their personal and private information is being safeguarded—even after it leaves SLTT government firewalls.

(A quick Internet search for “cybersecurity Recipients click on the link in the email and are posters” is a great place to start!) Talk about the taken to a well-crafted phishing page, hosted on a compromised website, that asks for their credentials. ILOVEYOU virus and the modern campaigns that use employee accounts to spread. If the employee enters their credentials, the phishers use those credentials to remotely log into the compromised account and send more phishing emails to everyone in the compromised employee’s
