The strength of the authentication process is described by an ordinal measurement called the AAL. AAL1 requires single-factor authentication and is permitted with a variety of different authenticator types. At AAL2, authentication requires two authentication factors for additional security. Authentication at the highest level, AAL3, additionally requires the use of a hardware-based authenticator and verifier impersonation resistance.
Shared secrets stored on authenticators may be either symmetric keys or memorized secrets (e.g., passwords and PINs), as opposed to the asymmetric keys described above, which subscribers need not share with the verifier. While both keys and passwords can be used in similar protocols, one important difference between the two is how they relate to the subscriber. While symmetric keys are generally stored in hardware or software that the subscriber controls, passwords are intended to be memorized by the subscriber. Since most users choose short passwords to facilitate memorization and ease of entry, passwords typically have fewer characters than cryptographic keys. Further, whereas systems choose keys at random, users attempting to choose memorable passwords will often select from a very small subset of the possible passwords of a given length, and many will choose very similar values. As such, whereas cryptographic keys are typically long enough to make network-based guessing attacks untenable, user-chosen passwords may be vulnerable, especially if no defenses are in place.

The "48 Dredge" is a futuristic FN Minimi-based design that is loosely based on the M249-E2 (despite the name alluding to the Mk 48 Mod 0), but fires 6-round bursts automatically in a similar fashion to the Pharo. Given the LMGs' priority of sheer volume of suppressing fire over accuracy, the burst-fire is quite counter-intuitive to the weapon's role, but is probably deliberate in order to balance its otherwise high fire rate with the slower-firing LMGs. The data vault hints that it is specifically designed to be a precision suppression weapon. It is stated to be chambered in the same absurdly small ".308mm" as the XR-2, features a similar "double-hop" burst system and is from the United Kingdom.
Unique constraints that could be encountered during the investigation should be identified. For instance, cybercrime investigators could encounter multiple digital devices, operating systems, and complex network configurations, which will require specialized knowledge, variations in collection procedures, and assistance in identifying connections between systems and devices (e.g., a topology of networks). Anti-forensics techniques (discussed in Cybercrime Module 4 on Introduction to Digital Forensics), such as steganography (i.e., the stealthy concealment of data by both hiding content and making it invisible) and encryption (i.e., "physically blocking third-party access to a file, either by using a password or by rendering the file or aspects of the file unusable;" Maras, 2014, p. 204; for more information on encryption, see Cybercrime Module 10 on Privacy and Data Protection), could also be encountered during an investigation (Conlan, Baggili, and Breitinger, 2016). Because of this, the investigator should be prepared for these situations and have the necessary human and technical resources needed to deal with these constraints. The actions taken by the investigator in these cases (e.g., the ability of the investigator to obtain the passwords to those devices and/or decrypt the files), if any, depends on national laws (see Global Partners Digital interactive map for more information on the encryption laws and policies of countries). Digital forensics tools (discussed in Cybercrime Module 4 on Introduction to Digital Forensics) can assist in this endeavour by, for example, identifying steganography and decrypting files, as well as perform other critical digital forensics tasks. Examples of such tools include Forensic Toolkit (FTK) by Access Data, Volatile Framework, X-Ways Forensics. Along with these resources, a forensic toolkit is needed, which contains the objects needed to document the crime scene, tools need to disassemble devices and remove other forms of evidence from the crime scene, and material needed to label and package evidence (e.g., for smartphones, a Faraday bag, which blocks wireless signals to and from the digital device, and a power bank are needed and used to transport them), among other items (Casey, 2011; Sammons, 2012; Maras, 2014; Nelson, Phillips, and Steuart, 2015).
Protecting a company from these attacks starts with education. Teaching people what to look for when getting an email or receiving a phone call from someone asking for information or to click on something is what's going to lessen the likelihood of a successful attack. Actually looking at the from address, hovering over links and verifying the URL, and never downloading attachments unless you absolutely know where the email comes from will drastically decrease the likelihood of a successful attack against a company. When an individual receives a phone call asking for information, it's important to establish the identity of the person without giving hints. Remember: people's information is easily found on the internet. Asking good security questions on the IT help desk level is a great way to help guard against these attacks. Something like: What high school did you go to, or what was the make of your first car, is a thousand times better than your birthday.
"I just need." Basically, someone calls the company claiming to represent the phone company, internet provider, etc., and starts asking questions. They claim to have a simple problem or know about a problem that can be fixed quickly but they just need one little thing. It could be as innocuous as asking for a username or someone's schedule or as blatant as asking for a password. Once the attacker has this information, they call someone else in the company and use the new information to refine their attack. Lather, rinse, repeat.
These attacks are highly effective if the criminal has done his homework and has all the relevant information. Where do criminals get the information in the first place? Well...this is where the Reconnaissance Phase comes into play. At this phase, which may take anywhere from several months to a year (hence the Persistent in APT) the criminal typically infects a few organizational computers with spyware and patiently sifts information and access credentials.
A Phishing email is a crafted email that pretends to be from a known trusted source and that could trick the user to download an attachment, click on a malicious link, or simply cooperate to provide sensitive information such as your passwords. These emails, for example, can be sent to an entire organization without targeting specific people in the company. Spear Phishing emails, on the other hand, are emails that are crafted specifically for a few people in an organization that could have valuable information for an attacker.
Phishing, in general, has been being used a lot for the past couple of years by cyber criminals to break into an organization. Ranked #3 on the Verizon Report in 2014, it was made clear that cyber criminals are focusing more on the human factor instead of the technology in place.This is because it is not expensive to craft a phishing email. There are open source tools such as SET (Social Engineering Toolkit) that could help an attacker to circumvent high-end technology. Spam filters are great, but they end up being a fundamental layer of security to an organization if the attacker knows how to trick the user into cooperating without making him or her click on a link. One perfect example would be receiving an email from your bank asking you to call a number provided in the email to change your ATM PIN. The cyber criminal provides a number where he is waiting to forward the communication to the real bank, but mirroring/capturing/sniffing the traffic or conversation that the user trusted the number in the email.
Spear Phishing - a more sophisticated form of phishing. Attackers behind spear phishing campaigns typically know more information about the victims and target them specifically. For example, in the recent case of the LastPass breach, email addresses were stolen (along with other information). These will likely be abused and the attackers will send out an email to the owners of those mailboxes that will resemble an official LastPass email that will recommend users to change their passwords, but when the users do so, they are in fact sending it to the cybercriminals. Similarly, spear phishing is one of the most effective ways to breach a network. Victims will usually receive a spoofed email from someone in the company with an important document, which will usually install malware or some type of Trojan that will be used to compromise their computer. This initial attack vector has proven itself extremely effective and is often used in high level cyberespionage campaigns.
Possibly password resets or attempts to gain access to confidential information, such as bank account information. A call center may be targeted when the hacker has some general information about a target, and they will use tenacity to extract additional information from the call center. Regular staff training is paramount for employees to learn social engineering attack techniques and ensure that they follow security best practice at all times. 2ff7e9595c
