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!

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.
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.
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.
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.
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.
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.
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.
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 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:
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.
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.
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.
Root Cause Analysis: The hunt for the smoking gun – the vulnerability exploited, the malware utilized, the attacker's tactics, techniques, and procedures (TTPs).
Containment and Mitigation: The clock is ticking. Analysts race to contain the damage, neutralize the threat, and patch vulnerabilities to prevent further harm.
Reporting and Learning: Sharing the intel is key. Analysts document their findings, identify lessons learned, and update defensive strategies for future battles.
Tools of the Trade: Unmasking the Arsenal
Just like any detective needs their magnifying glass, intrusion analysts rely on sophisticated tools:
SIEM (Security Information and Event Management): The all-seeing eye, aggregating logs from across the network and providing real-time threat detection.
Network Traffic Analyzers: Deciphering the digital whispers, these tools monitor and analyze network traffic to identify malicious activity.
Forensic Suites: Like CSI for computers, these tools extract and analyze evidence from compromised systems, revealing hidden tracks and artifacts.
Malware Analysis Tools: Peering into the dark hearts of malicious software, these tools dissect malware samples, uncovering their functionalities and identifying potential indicators of compromise (IOCs).
Threat Intelligence Feeds: Sharing the intelligence gathered, these feeds keep analysts abreast of the latest threats, tactics, and vulnerabilities.
Beyond the Binary: The Faces of Intrusion Analysis
The field of intrusion analysis is a bustling ecosystem, home to diverse roles and specialties:
Incident Responders: The firefighters on the front lines, rapidly responding to security incidents and neutralizing threats.
Forensic Analysts: The digital detectives, meticulously collecting and analyzing evidence to reconstruct the attack timeline and identify the perpetrators.
Malware Analysts: The code whisperers, dissecting malware samples to understand their functionalities, identify vulnerabilities, and track attacker footprints.
Threat Hunters: The proactive vigilantes, scouring the digital landscape for hidden threats and proactively mitigating potential risks.
Security Engineers: The architects of defense, building and maintaining secure systems and implementing preventative measures.

The Marriage of Minds: Malware Analysis and Intrusion Analysis
Like Holmes and Watson, malware analysis and intrusion analysis are partners in crime-solving. Malware analysis delves into the malicious code itself, understanding its workings, capabilities, and potential targets. This intel feeds directly into intrusion analysis, providing crucial context for understanding the attacker's intent and methods.
By analyzing malware samples identified during an intrusion, analysts can:
Identify Indicators of Compromise (IOCs): Unique signatures, file hashes, or network characteristics that reveal the presence of the same malware elsewhere in the network, helping to identify compromised systems and assess the scope of the attack.
Understand Attack Objectives: By deciphering the malware's functionalities, analysts can determine the attacker's goals, whether it's data theft, system disruption, or lateral movement within the network.
Trace Attacker TTPs: Malware often contains embedded information and communication channels, offering insights into the attacker's tools, techniques, and tradecraft, which can be used to track their movements and predict future attacks.
Develop Detection and Mitigation Strategies: Understanding the malware's modus operandi allows analysts to craft targeted detection rules and preventative measures to block similar attacks in the future.
This symbiotic relationship between malware analysis and intrusion analysis is crucial for comprehensive threat assessment and effective incident response. Malware analysts act as the code breakers, deciphering the attacker's secret language, while intrusion analysts utilize this knowledge to paint the bigger picture, map the attack landscape, and ultimately, safeguard the digital perimeter.
Beyond the Battlefield: The Societal Impact of Intrusion Analysis
Intrusion analysis isn't just about protecting individual organizations. It has far-reaching societal implications, playing a vital role in:
Combating Cybercrime: Intrusion analysts, alongside law enforcement agencies, can track cybercriminal activity, identify criminal networks, and gather evidence for prosecution.
Securing Critical Infrastructure: Protecting critical infrastructure like power grids, healthcare systems, and financial institutions from cyberattacks ensures the smooth functioning of society and vital services.
