Welcome to Tech Talks By Noah! In this week's tech talk we will discuss malware, and the different types of malware. Malware is prevalent in today's cyber landscape. Every week there is a new data breach in the news, most likely relying on malware to steal sensitive data from the victim. Malware is a critical part of hacker's toolset to infiltrate organizations.

There are multiple types of malware that attackers use. These types of malware serve different goals and objectives but they are just as destructive. The first type of malware we are going to discuss are rootkits.

Rootkits

Rootkits are a particularly nasty type of malware. Rootkits hide deep in the hard drive and load up before the operating system, preventing anti-virus from detecting the rootkit. Therefore, it is extremely hard to remove rootkits from the computer since they cannot be detected. However, there are such things as rootkit scanners that load before the operating system to detect if there is a rootkit hiding on the hard drive. These rootkit scanners are a complete anti-virus. Furthermore, some Linux based operating systems include security tools to remove rootkits and conduct drive forensics.

Viruses

Viruses are one of the most commonly known types of malware. Viruses spread by attaching themselves to an executable file (such as a document) and run when the file is executed. By attaching itself to an executable a virus is able to spread quickly and efficiently. However, since a virus relies on an executable, it has less of a chance of being executed than a worm.

Worms

A worm is a type of malware that spreads through the the network. They are a self-replicating malware that spread without user intervention (unlike viruses). Worms do not need an executable file to spread, allowing them to spread easier than viruses. Worms spread quickly and often transverse network boundaries to infect areas as large as countries, or in some cases worms can infect the entire internet.

Trojan Horse

Trojan horses are a type of malware that embeds itself within another legitimate program. Which allows the trojan to masquerade itself to trick users into executing the program, thereby infecting their computer with the malware.

Conclusion

In this article, we covered a few types of malware that are commonly seen in the wild. By understanding the different types of malware and their functions, you can be better prepared to prevent malware infections and keep yourself cyber safe!

Its prevalence is astounding. A subtle form of information gathering, often unnoticed due to its subtle hacking of the human mind. Social engineering is a catch-all term for a wide variety of cyberattacks that rely on manipulating the human psyche to gain unauthorized access to privileged information. Social engineering is one of the most common information gathering tools that threat actors use to scope out a target or gain initial access by using legitimate credentials for nefarious purposes.

Types of Social Engineering

There are multiple types of social engineering. Common types include Phishing, Smishing, Vishing, Spear Phishing, Dumpster Diving, Shoulder Surfing, and Tailgating. Let's dive deeper into each of these types of attacks.

  1. Phishing
    • Phishing attacks are social engineering attacks designed to harvest user credentials or infect the recipient of these attacks with malware. Phishing attacks are most commonly conducted through email, using false pretenses such as a requested password reset, or a user support request. This allows attackers to gain access to credentials from unsuspecting users, thus giving the attackers access to otherwise protected systems.
  2. Smishing
    • Smishing is a sub type of phishing attack that is preformed over SMS (text) messaging. Attackers send fraudulent text messages purporting to be from some kind of reputable company. In these messages, attackers generally include some kind of link to a phishing site or a link to a malware site. These attacks allow hackers to gain access to user credentials such as bank account and credit card information, mobile phone carrier accounts, and authenticator accounts.
  3. Vishing
    • Vishing is type of phishing attack that relies on interactions with victims over the phone. Attackers interact with users and use social engineering techniques to gather information. Attackers then use this information to access user accounts.
  4. Spear Phishing
    • Spear phishing is a type of targeted phishing attack where the users are specifically targeted to gain access to important user account. Victims are often prominent users such as system administrators, organizational admins, etc.
  5. Dumpster Diving
    • Dumpster diving is a form of social engineering attack in which the attacker goes through an organization's trash to look for valuable documents such as financial information, Personally Identifiable Information, passwords, etc.
  6. Shoulder Surfing
    • Shoulder surfing is a form of social engineering attack where attackers look over the shoulder of the victim to gain user credentials. Attackers then use these credentials to access user accounts, or they sell the credentials on the dark web for profit. One solution to this is the use of privacy screens.
  7. Tailgating
    • Lastly, we have tailgating. Tailgating is a form of social engineering where the attacker follows legitimate users into a controlled area. In one example, attackers take advantage of the common courtesy of holding the door for people. A simple solution to this is to use mantraps/access control "airlocks".

This is just a few examples of all of the different types of social engineering. There are many more to cover. I encourage you to do some more reading on your own time.

Intrusion Analysis is the Art of detecting intruders within secure networks and safeguarding the sensitive data stored on that network from unauthorized access. Learning intrusion analysis can be an artform within itself. The goal of this guide is to give you a stepping stone into the world of Intrusion Analysis, and to help you successfully learn the basics of that artform.

What is Intrusion Analysis?

Intrusion analysis is process of detecting and mitigating the threat of unauthorized access to an organization's secure networks. Intrusion analysis is a critical component of an organization's information systems security plan. It utilizes multiple software tools to detect, manage, and mitigate intrusions. Intrusion analysis captures traffic that traverses computer networks and activities/events that happen on endpoints.

This information is gathered via intrusion detection systems and OS/application log files. These log files and IDS alerts (usually stored in a IDS log file) are often aggregated into a single database and analyzation tool known as a Security Information and Event Management (SIEM) system. SIEM systems and various network and endpoint monitoring tools are a quintessential (and powerful) combination to detect and manage threats.

How to Analyze Intrusions

Intrusion analysis follows a very methodical approach, similar to a forensic investigation:

  1. Incident Detection: The intrusion analysis process is kickstarted when a intrusion attempt alert is received (usually in a SIEM solution via network or endpoint security solutions). The network/endpoint security solutions will detect attempted malicious activity and push out an alert to the SIEM system to notify an incident responder/security analyst for review.
  2. Data Gathering: Once the incident response process is triggered, analysts comb the network and hosts for any shred of evidence that indicates an intrusion or data leak. Logs, network traffic, system memory dumps – every digital crumb becomes crucial evidence.
  3. Timeline Reconstruction: Intrusion analysts carefully construct a timeline of the attack. This timeline is key in determining the extent of the attack and what kind of information the attackers stole. Time becomes the canvas.
  4. Root Cause Analysis: The hunt for the smoking gun – the vulnerability exploited, the malware utilized, the attacker's tactics, techniques, and procedures (TTPs).
  5. Containment and Mitigation: The clock is ticking. Analysts race to contain the damage, neutralize the threat, and patch vulnerabilities to prevent further harm.
  6. Reporting and Learning: Sharing the intel is key. Analysts document their findings, identify lessons learned, and update defensive strategies for future battles.
