Wireless Attacks

Wireless Attacks:

There are several known attacks against the wireless networks. Most can be avoided by using strong security protocols such as WPA2 and CCMP.

Disassociation Attacks:
This attack effectively removes the wireless client from the wireless network. In disassociation attack, attackers send a disassociation frame to the AP with spoofed MAC address of the victim. The AP receives the frame and shutdown the connection. Victim then disconnected from the AP and need to go through the authentication process again to reconnect.

WPS Attack:
WPS is susceptible to the brute force attack. This attack keep trying different PINs until it succeeds. Once it discover the PIN, it can discover the passphrase in both WPA2 and WPA networks.

Rogue AP:
Rogue AP is an AP placed within a network without official authorization. It might be installed by the employee or attacker. Attacker may connect to a rogue access point to network devices in wireless closets that lack adequate physical security. This access point acts as a sniffer to capture traffic passing through the wired network device, and then broadcast the traffic using the wireless capability of AP. The attacker can then capture the exfiltrated data files.

Evil Twin:
An evil twin is a rogue access point with the same SSID as a legitimate access point. An attacker can set up an AP using the same SSID as the public WIFI network, and many users may connect with this evil twin. Once users connect to this evil twin. All traffic goes through this evil twin instead of legitimate AP. Attackers can then create a fake web page to steal the credentials.

Jamming Attack:
Attackers can transmit noise or another radio signal on the same frequency used by the wireless network. This interferes with the transmission and can seriously degrade performance. This type of denial-of-service is known as jamming.

IV Vector:
A wireless initialization vector attack attempts to discover the pre-shared key form the IV. The IV is simple a number. Some wireless protocols use an IV by combining it with pre-shared key to encrypt the data in transit. An IV attack is successful when an encryption system reuse the same IV. Moslty small IV results in reusing the key again.

Wireless Replay Attack:
In a replay attack, an attacker captures data sent between two entities, modifies it, and then attempts to impersonate one of the parties by replaying the data.

Cyber Threat Intel

What is Cyber Threat Intel? Threat intel is the information about the threats. Cyber threat intel is used to better understand, predict and adopt to the behavior of malicious actors. It plays an important role in preventing the zero-day attacks. " Threat information that has been aggregated, transformed, analyzed, interpreted, or enriched to provide the necessary context for decision-making processes " (NIST). Threat Intel life Cycle: Intelligence lifecycle is the process of developing raw information into finished intelligence for policymaker to use in decision making and action. CTI Life Cycle Planning and Direction Planning and direction helps in setting up the goals for the threat intel program. Priorities and requirements are defined in this phase. Collection: Collection means gathering of data to produce the finished intelligence. Data includes logs(Firewall, IPS/IDS, Endpoints), threat feeds and OSINT(reports, social media, public forums). Collection Types of Collectio...

Analyzing Spear Phishing Email

Image
Phishing is the technique of fraudulent attempt by the attacker to obtain sensitive and confidential information i.e. Credentials, PII information, credit card, bank details. It can also be targeted attack to focus on the specific organization of individual. The attacker often tailors an email to speak directory to targeted user. There are many types of phishing as follow. I wouldn't explain the types. You can read Here . In this article you'll learn how to analyze the sophisticated phishing email. So, Let's start the case study to explain.  Spearphising :  Spearphising is the technique in which attacker aims at one person and lures him/her into providing confidential data. Attacker compile the email according to the specific user. The email would consist some of the target's email, username, designation.  Case Study: User receive the spearphising email containing the PDF attachment with double extension. Email body contains the unprofessional statement "Kindly m...

Advance Attacks on Network

  Advance Attacks and Protection: In this section we will discuss some common types of attacks that can be launched against the systems and networks. Spoofing: Spoofing occurs when one person or entity impersonates or masquerades as someone or something else. There are two common types of spoofing attack one is IP spoofing and the other one is MAC spoofing. We can prevent IP spoofing by blocking the packet if it contains the private IP address on public interface. SYN Flood Attack: The SYN Flood attack is a common attack used against servers on the internet. They are very easy for attackers to launch and difficult to stop, and can cause significant problems. It can disrupt the TCP handshake process and can prevent legitimate clients from connecting. In a SYN flood attack, the attacker never completes the handshake by sending the ACK packet. So it consumes the server resources. We can prevent it by setting the threshold for SYN packet. MITM: Man in the Middle attack is a form of act...
