Stopping Social Engineering Attacks No, Slow Down Yes!

Elements of an Attack:

From the article at TechNewsWorld.

Social Engineering is equivalent to scammers trying all types of methods to gain information or money.

What does it mean to have an image above that shows many possible Social engineering attacks?

Let’s list them:

  1. Techniques
    1. Phishing
    2. Pretexting
    3. Baiting
    4. Quid Pro Quo
  2. Compliance principles
    1. Friendship or liking
    2. Commitment or Consistency
    3. Scarcity
    4. Reciprocity
    5. Social Validation
    6. Authority
  3. Target
    1. Individual
    2. Organization
  4. Goal
    1. financial Gain
    2. Unauthorized Access
    3. Service Disruption
  5. Medium
    1. E-mail
    2. Face-to-face
    3. Telephone
    4. SMS
    5. Paper Mail
    6. Storage Media
    7. Webpage
    8. Pamphlets

And the above methods are only the current or ‘older’ attacks. Each heading is followed by the specific attack method. And these methods are all focused on taking resources or information to eventually relieve you of money.

Now social engineeringattack advances  has added Vishing – which is attempting to influence an action by calling/contacting a mobile phone which requires a quick action.

Impersonation is the practice of pretexting as another person with the goal of obtaining information or access to a person, company, or computer system. (another newer method)

Sometimes the goal is to gain information not actually steal resources($  or computer time) at first. Only after a lot of information gathering is a unique social engineering attack going to go for the jugular and the money they are all after.

 

So what can be done to slow down or reduce the attacks (Under no illusion to completely stop all attacks).

Introduce a process or method – let me take your information and I will call you back. (most phishers will not want to give a number). Authenticate the person’s number to make sure it is legitimate.

Also make a rule never to give out personal information on an incoming call – have a standard response available. ” Mr./Mrs./Ms/ you can understand that with all of the possible hacker attacks we do not give out any(or xyz) information via phone” If needed I can call you back tomorrow, am busy now.

No matter how you are being contacted the response can be changed… On an incoming text we do not give out personal information. Please give me another phone # so I can contact you tomorrow.

Do not respond to texts with information, require a call and other contacts to verify the authenticity of caller.

A social engineering attack can be complex but it really has the same goal as all hacker attacks to take resources and information from you. If you can slow them down, make them work harder to get what they want. then you are most of the way to a secure and safe network.

October is Cybersecurity Awareness Month

In a year of many problems and issues the Department of Homeland Security decided to make October the National Cyber Security Awareness Month (NCSAM) since 2003.

https://www.dhs.gov/national-cyber-security-awareness-month

 

The Theme is Own IT. Secure IT. Protect IT.

Own IT is reminding you to travel with cybersecurity in mind (at least some of the time), Social media usage and online privacy should be connected and though about how to use social media. the Internet of things devices should be sought out and updated or reviewed to make sure they are secure.

Secure IT is typical, a focus on Strong Passwords, but we could talk about just changing default passwords would be good too.  The famous xkcd image is interesting:

passwords leads to MFA or Multi-Factor-Authentication.

MFA is required or suggested for in NIST 800-171.

Phishing we discussed in a recent blogpost: https://oversitesentry.com/top-cybersecurity-problem-for-small-business/

Securing your ecommerce may be simple or common sense…  But has to be guided by OWASP as I discussed in https://oversitesentry.com/owasp-has-new-testing-guidelines-document/

 

The Secure IT portion is a combination of things:

  • Patch your software
  • Be aware of how you share personal information of employees or customers PII (Personally Identifiable Information)

Keep in mind a simple strategy to  protect yourself and your company ZeroTrust

ZeroTrust  means do not implicitly  trust. First verify trustworthiness before doing business and granting access.

Zero Trust is used in many manufacturer network architectures, such as Cisco:

https://www.cisco.com/c/en/us/products/security/zero-trust.html

or Palo Alto:

https://www.paloaltonetworks.com/cyberpedia/what-is-a-zero-trust-architecture

“In Zero Trust, you identify a “protect surface.” The protect surface is made up of the network’s most critical and valuable data, assets, applications and services – DAAS, for short. Protect surfaces are unique to each organization. Because it contains only what’s most critical to an organization’s operations, the protect surface is orders of magnitude smaller than the attack surface, and it is always knowable.”

 

This is a good strategy for 2019 Cybersecurity awareness… Do not assume a social media connection until verified. Email link, email attachment, phone call and many other possible attacks to your business.  Unfortunately this means sometimes mistaking or requiring a possible customer to prove who they are, but with some thought this can be done tactfully so that a potential customer can see why this is being done.

Top Cybersecurity Problem for Small Business

The top Cybersecurity problem (or risk) is phishing emails and ransomware downloaded to your computer or your website.

 

When a phishing email somehow gets you to click a link that then downloads an infected “payload” into your computer you can only hope that the anti-virus you have (and/or firewall) will protect you from the payload.   So that a dangerous payload may not be able to take advantage of your inaction.  The bad software is either in an attachment (in email) or on a website that you download (from a link).

 

Obviously if you can learn to recognize phishing scams that  would be a good thing. but there are other things to do even if you click on a bad link or attachment.

4 things to help prevent getting hacked:

  1. Phishing email spotting  (this is the trickiest one)
  2. Update your computer and software (easiest to setup and manage)
  3. Use multi-factor authentication wherever you can
  4. Backup your computer regularly

if you are up-to-date with your patching with as much software as possible, many attacks will fail. There are some ‘zero-day’ attacks that would still be successful against you, but those are expensive for hackers ‘usually’, so the risk is low for a ‘silver bullet attack’.

Osterman Research created a white paper for Trend Micro: “New Methods for Solving Phishing, Business Email Compromise, Account Takeovers and Other Security Threats”.

First the paper explains how ineffective a number of people have been in managing phishing attacks.

The central theme in the paper are phishing attempts that reach end users and employees who fail to recognize phishing and social engineering attacks.

One of the paper’s recommendations is to move your security operation to the cloud. The plan is that the cloud provider is more advanced than you and will reduce your risk.

What is clear though is that even on the cloud certain scams are always going to take advantage of any system. For example if someone calls you and you give them your credentials after some story that seems believable then any new technology that you paid for is useless. because now the bad guys can log in with your username and password.

You can set up MFA (Multi-factor Authentication) which means the hacker has to defeat another level of authentication (connected to your cellphone or a physical secure id mechanism).

 

I do not want to get into the technical details of MFA, since that  is beyond the scope of this article.  But MFA would cut down attacks by a large percentage.

So education and MFA with a better anti-phishing  email solution would reduce successful attacks and a proper patching environment may cover the rest.

Why Are Hackers Successful?

The Number 1 reason is: “We do not do an adequate job of patching and paying attention to security!”

Again and again we can find reports and stories of entities not doing basic tasks:

Above image is from Protiviti report

 

Why are the basics not being done?

Because a concerted effort to manage IT tasks month after month is not easy, and in fact it is a difficult challenge.  What is difficult about regular every day life in patching hundreds of systems on a monthly basis at minimum?

Well, let’s list a few problems that arise:

  1. Personnel challenges – sickness, vacation, doctor visits, kids, parents, brothers, sisters, and spouse conflicts.
  2. So many things can go wrong with the actual device itself even when used correctly…  Or if this is a laptop, then it has to be plugged into the network with VPN or directly on the network for it to download and get updated.
  3. Above 2 are the normal challenges, how about abnormal challenges? What about somebody installing a new software that conflicts with the patch? Now the patch does not install correctly and the system is vulnerable to attack.

 

So knowing some of these items means management has to schedule and account for potential problems which means it costs more resources sometimes than anticipated.   This may be a problem, and then management  pushes back onto IT to say no more OT this month!

In basic terms – stuff happens and then patches are not applied. If this management process is more broken than fixed there will be plenty of chances for hackers to attack.

It depends on the maturity of management thoughts and actions. Is management more willing to make sure the patches are applied or are they willing to let patches slide for a little while?

The answer is to create processes to fulfill compliance mandates and do not deviate from this method.

I.e. quarterly meetings at minimum with required review and testing of all systems that are important and potential other systems.

Punch line? Hackers are successful due to the failure of management actions and thoughts in regards to cybersecurity.

Linux Rootkits Hard to Detect

First of all what is a rootkit?

A collection of software that runs and tries to hide from the computer user and administrator while also allowing the attacker access to the computer.

It does this by connecting as ‘root’ to the Operating System kernel.  In Linux ‘root’ is the administrator.

If you can masquerade as root and hijack system calls then there is a way software can be written to get  root access allowing the software to hide itself in the Linux system.

I am not going to tell you how to create rootkits, as there are many a people on the Internet who have done so and show you what they have done.

Marcus Hodges at Thotcon had a 1 hour presentation about how to hide from the operating system. To hijack operating system calls that then are used to create the rootkit.

Once system calls are hijacked the attacker can create hidden areas on the file system to stow and stay quiet until more objectives are to be pursued.

In the Cyber Kill chain the rootkit performs the function of persistence – keeping a presence on the attacked network.

A decent command to find out what different commands do on a system: strace – commands for troubleshooting and debugging Linux
