NEW QUESTION 139
jane, an ethical hacker. Is testing a target organization's web server and website to identity security loopholes. In this process, she copied the entire website and its content on a local drive to view the complete profile of the site's directory structure, file structure, external links, images, web pages, and so on. This information helps jane map the website's directories and gain valuable information. What is the attack technique employed by Jane in the above scenario?
- A. website mirroring
- B. Web cache poisoning
- C. Session hijacking
- D. Website defacement
Answer: A
Explanation:
A mirror site may be a website or set of files on a computer server that has been copied to a different computer server in order that the location or files are available from quite one place. A mirror site has its own URL, but is otherwise just like the principal site. Load-balancing devices allow high-volume sites to scale easily, dividing the work between multiple mirror sites. A mirror site is typically updated frequently to make sure it reflects the contents of the first site. In some cases, the first site may arrange for a mirror site at a bigger location with a better speed connection and, perhaps, a better proximity to an outsized audience. If the first site generates an excessive amount of traffic, a mirror site can ensure better availability of the web site or files. For websites that provide copies or updates of widely used software, a mirror site allows the location to handle larger demands and enables the downloaded files to arrive more quickly. Microsoft, Sun Microsystems and other companies have mirror sites from which their browser software are often downloaded. Mirror sites are wont to make site access faster when the first site could also be geographically distant from those accessing it. A mirrored web server is usually located on a special continent from the principal site, allowing users on the brink of the mirror site to urge faster and more reliable access. Mirroring an internet site also can be done to make sure that information are often made available to places where access could also be unreliable or censored. In 2013, when Chinese authorities blocked access to foreign media outlets just like the Wall Street Journal and Reuters, site mirroring was wont to restore access and circumvent government censorship.

Answer: B
Explanation:
Explanation
We discovered serious weaknesses in WPA2, a protocol that secures all trendy protected Wi-Fi networks. an attacker within range of a victim will exploit these weaknesses using key reinstallation attacks (KRACKs).
Concretely, attackers will use this novel attack technique to scan info that was previously assumed to be safely encrypted. this will be abused to steal sensitive info like mastercard numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. depending on the network configuration, it's additionally doable to inject and manipulate information. as an example, an attacker can be ready to inject ransomware or alternative malware into websites.The weaknesses are within the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected. to forestall the attack, users should update affected products as soon as security updates become offered. Note that if your device supports Wi-Fi, it's most likely affected.
during our initial analysis, we have a tendency to discovered ourselves that android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, area unit all affected by some variant of the attacks. For more info about specific products, consult the info of CERT/CC, or contact your merchant.The analysis behind the attack are presented at the pc and Communications Security (CCS) conference, and at the Black Hat Europe conference. Our detailed analysis paper will already be downloaded.Update October 2018: we've a follow-up paper wherever we generalize attacks, analyze additional handshakes, bypass Wi-Fi's official defense, audit patches, and enhance attacks using implementation-specific bugs.
DEMONSTRATIONAs a proof-of-concept we have a tendency to executed a key reinstallation attack against an robot smartphone. during this demonstration, the attacker is in a position to decrypt all information that the victim transmits. For an attacker this is often straightforward to accomplish, as a result of our key reinstallation attack is exceptionally devastating against UNIX system and robot half dozen.0 or higher. this is} as a result of robot and UNIX system can be tricked into (re)installing an all-zero encryption key (see below for additional info). once offensive other devices, it's harder to decrypt all packets, though an outsized variety of packets will nevertheless be decrypted. In any case, the subsequent demonstration highlights the kind of knowledge that an attacker will acquire once activity key reinstallation attacks against protected Wi-Fi networks:Our attack isn't restricted to sick login credentials (i.e. e-mail addresses and passwords). In general, any information or info that the victim transmits may be decrypted. in addition, counting on the device being employed and also the network setup, it's additionally doable to decipher information sent towards the victim (e.g. the content of a website). though websites or apps might use HTTPS as a further layer of protection, we have a tendency to warn that this additional protection will (still) be bypassed during a worrying variety of things. as an example, HTTPS was previously bypassed in non-browser package, in Apple's iOS and OS X, in robot apps, in robot apps once more, in banking apps, and even in VPN apps.
DETAILSOur main attack is against the 4-way handshake of the WPA2 protocol. This handshake is executed once a consumer needs to hitch a protected Wi-Fi network, and is employed to confirm that each the consumer and access purpose possess the right credentials (e.g. the pre-shared secret of the network). At identical time, the 4-way handshake additionally negotiates a recent encoding key that may be wont to write all sequent traffic. Currently, all trendy protected Wi-Fi networks use the 4-way handshake. this suggests of these networks area unit suffering from (some variant of) our attack. for example, the attack works against personal and enterprise Wi-Fi networks, against the older WPA and also the latest WPA2 normal, and even against networks that solely use AES. All our attacks against WPA2 use a completely unique technique known as a key reinstallation attack (KRACK):Key reinstallation attacks: high level descriptionIn a key reinstallation attack, the adversary tricks a victim into reinstalling an already-in-use key. this is often achieved by manipulating and replaying science handshake messages. once the victim reinstalls the key, associated parameters like the progressive transmit packet variety (i.e. nonce) and receive packet variety (i.e. replay counter) area unit reset to their initial price. primarily, to ensure security, a key ought to solely be put in and used once. sadly, we have a tendency to found this is often not secure by the WPA2 protocol. By manipulating cryptographic handshakes, we are able to abuse this weakness in observe.
Key reinstallation attacks: concrete example against the 4-way handshakeAs represented within the introduction of the analysis paper, the concept behind a key reinstallation attack may be summarized as follows. once a consumer joins a network, it executes the 4-way handshake to barter a recent encoding key.
it'll install this key once receiving message three of the 4-way acknowledgement. Once the key's put in, it'll be wont to write traditional information frames mistreatment associate encoding protocol. However, as a result of messages is also lost or born, the Access purpose (AP) can transmit message three if it didn't receive an appropriate response as acknowledgment. As a result, the consumer might receive message three multiple times. every time it receives this message, it'll instal identical encoding key, and thereby reset the progressive transmit packet variety (nonce) and receive replay counter utilized by the encryption protocol. we have a tendency to show that associate attacker will force these time being resets by collecting and replaying retransmissions of message three of the 4-way handshake. By forcing time being recycle during this manner, the encoding protocol may be attacked, e.g., packets may be replayed, decrypted, and/or solid. the same technique may also be wont to attack the cluster key, PeerKey, TDLS, and quick BSS transition handshake.

NEW QUESTION 148
Jason, an attacker, targeted an organization to perform an attack on its Internet-facing web server with the intention of gaining access to backend servers, which are protected by a firewall. In this process, he used a URL https://xyz.com/feed.php?url:externaIsile.com/feed/to to obtain a remote feed and altered the URL input to the local host to view all the local resources on the target server. What is the type of attack Jason performed In the above scenario?
- A. Web server misconfiguration
- B. website defacement
- C. web cache poisoning attack
- D. Server-side request forgery (SSRF) attack
Answer: D
Explanation:
Explanation
Server-side request forgery (also called SSRF) is a net security vulnerability that allows an assaulter to induce the server-side application to make http requests to associate arbitrary domain of the attacker's choosing.
In typical SSRF examples, the attacker might cause the server to make a connection back to itself, or to other web-based services among the organization's infrastructure, or to external third-party systems.
Another type of trust relationship that often arises with server-side request forgery is where the application server is able to interact with different back-end systems that aren't directly reachable by users. These systems typically have non-routable private informatics addresses. Since the back-end systems normally ordinarily protected by the topology, they typically have a weaker security posture. In several cases, internal back-end systems contain sensitive functionality that may be accessed while not authentication by anyone who is able to act with the systems.
In the preceding example, suppose there's an body interface at the back-end url https://192.168.0.68/admin.
Here, an attacker will exploit the SSRF vulnerability to access the executive interface by submitting the following request:
POST /product/stock HTTP/1.0
Content-Type: application/x-www-form-urlencoded
Content-Length: 118
stockApi=http://192.168.0.68/admin

NEW QUESTION 154
Harry. a professional hacker, targets the IT infrastructure of an organization. After preparing for the attack, he attempts to enter the target network using techniques such as sending spear-phishing emails and exploiting vulnerabilities on publicly available servers. Using these techniques, he successfully deployed malware on the target system to establish an outbound connection. What is the APT lifecycle phase that Harry is currently executing?
- A. Cleanup
- B. initial intrusion
- C. Persistence
- D. Preparation
Answer: B
Explanation:
After the attacker completes preparations, subsequent step is an effort to realize an edge within the target's environment. a particularly common entry tactic is that the use of spearphishing emails containing an internet link or attachment. Email links usually cause sites where the target's browser and related software are subjected to varied exploit techniques or where the APT actors plan to social engineer information from the victim which will be used later. If a successful exploit takes place, it installs an initial malware payload on the victim's computer. Figure 2 illustrates an example of a spearphishing email that contains an attachment. Attachments are usually executable malware, a zipper or other archive containing malware, or a malicious Office or Adobe PDF (Portable Document Format) document that exploits vulnerabilities within the victim's applications to ultimately execute malware on the victim's computer. Once the user has opened a malicious file using vulnerable software, malware is executing on the target system. These phishing emails are often very convincing and difficult to differentiate from legitimate email messages. Tactics to extend their believability include modifying legitimate documents from or associated with the organization. Documents are sometimes stolen from the organization or their collaborators during previous exploitation operations. Actors modify the documents by adding exploits and malicious code then send them to the victims. Phishing emails are commonly sent through previously compromised email servers, email accounts at organizations associated with the target or public email services. Emails also can be sent through mail relays with modified email headers to form the messages appear to possess originated from legitimate sources. Exploitation of vulnerabilities on public-facing servers is another favorite technique of some APT groups. Though this will be accomplished using exploits for known vulnerabilities, 0-days are often developed or purchased to be used in intrusions as required .
NEW QUESTION 155
Nicolas just found a vulnerability on a public-facing system that is considered a zero-day vulnerability. He sent an email to the owner of the public system describing the problem and how the owner can protect themselves from that vulnerability. He also sent an email to Microsoft informing them of the problem that their systems are exposed to. What type of hacker is Nicolas?
- A. white hat
- B. Black hat
- C. Gray hat
- D. Red hat
Answer: A
Explanation:
A white hat (or a white hat hacker) is an ethical computer hacker, or a computer security expert, who focuses on penetration testing and in other testing methodologies that ensures the safety of an organization's information systems. Ethical hacking may be a term meant to imply a broader category than simply penetration testing. Contrasted with black hat, a malicious hacker, the name comes from Western films, where heroic and antagonistic cowboys might traditionally wear a white and a black hat respectively. While a white hat hacker hacks under good intentions with permission, and a black hat hacker, most frequently unauthorized, has malicious intent, there's a 3rd kind referred to as a gray hat hacker who hacks with good intentions but sometimes without permission. White hat hackers can also add teams called "sneakers and/or hacker clubs",red teams, or tiger teams. While penetration testing concentrates on attacking software and computer systems from the beginning - scanning ports, examining known defects in protocols and applications running on the system and patch installations, as an example - ethical hacking may include other things. A full-blown ethical hack might include emailing staff to invite password details, searching through executive's dustbins and typically breaking and entering, without the knowledge and consent of the targets. Only the owners, CEOs and Board Members (stake holders) who asked for such a censoring of this magnitude are aware. to undertake to duplicate a number of the destructive techniques a true attack might employ, ethical hackers may arrange for cloned test systems, or organize a hack late in the dark while systems are less critical. In most up-to-date cases these hacks perpetuate for the long-term con (days, if not weeks, of long-term human infiltration into an organization). Some examples include leaving USB/flash key drives with hidden auto-start software during a public area as if someone lost the tiny drive and an unsuspecting employee found it and took it. Some other methods of completing these include: * DoS attacks * Social engineering tactics * Reverse engineering * Network security * Disk and memory forensics * Vulnerability research * Security scanners such as: - W3af - Nessus - Burp suite * Frameworks such as: - Metasploit * Training Platforms These methods identify and exploit known security vulnerabilities and plan to evade security to realize entry into secured areas. they're ready to do that by hiding software and system 'back-doors' which will be used as a link to information or access that a non-ethical hacker, also referred to as 'black-hat' or 'grey-hat', might want to succeed in .
