Here are some techniques that AI can use to refine social engineering tactics:
- Data Analysis: AI algorithms can analyze vast amounts of personal and behavioral data from various sources, including social media profiles, public records, and online activities. This analysis helps fraudsters understand their targets better and tailor their social engineering techniques accordingly.
- Natural Language Processing (NLP): AI-powered NLP algorithms can analyze the communication patterns and language used by individuals and organizations. This allows fraudsters to mimic the writing style, tone, and vocabulary of the target, making the phishing emails more convincing and difficult to distinguish from genuine communication.
- Personalization: AI can leverage the data collected on individuals to personalize phishing emails. This includes using the recipient's name, job title, company information, or referencing recent interactions or events specific to the target. Personalization enhances the credibility of the phishing attempt and increases the chances of a successful response.
- Contextual Information: AI algorithms can gather contextual information about the target's industry, organization, or role. This knowledge allows fraudsters to craft phishing emails that appear relevant, timely, and aligned with the target's professional responsibilities or interests.
- Behavioral Analysis: AI can analyze the behavioral patterns of individuals, including their online activities, browsing history, and social connections. By understanding the target's behavior, fraudsters can design phishing emails that align with their preferences and interests, increasing the chances of engagement.
- Social Network Analysis: AI can analyze social connections, both within and outside the target's professional network. This analysis helps fraudsters identify relationships, influencers, and trusted contacts that can be exploited in the phishing attempt, making the email appear more trustworthy and legitimate.
- Psychological Manipulation: AI-powered algorithms can leverage psychological principles to manipulate emotions and decision-making processes. By analyzing psychological profiles and behavioral data, fraudsters can craft phishing emails that evoke fear, curiosity, urgency, or excitement, leading to impulsive responses from the targets.

Consejos de seguridad:
- Use multiple passwords everywhere. It is NOT okay to use the same passwords for social networking sites as long as you use different passwords for home banking-type sites. It is correct to use a different password for home banking type sites. However, social networking sites may not have the security of your online financial institution but using the same password on those sites is like trusting the weakest link in a chain to carry the same weight. Every site has vulnerabilities, plan for them to be exploited.
- If you do receive offers of pre-approved credit, you should shred the offer before putting them in the trash. First, you should purchase a cross-cut shredder and shred all your pre-approved credit card offers. Next, you should remove your name and opt-out of receiving these offers by visiting the website: https://www.optoutprescreen.com
- Understand how your financial institution communicates with you. If you receive an e-mail with your bank's name and e-mail address, explaining that, for security reasons, you had to click on a particular Internet link and log in to your account to update your settings. You should delete the email without taking any action, call or otherwise contact your bank or credit union to ensure credibility and report it to your bank as SPAM. Financial institutions DO NOT ask for personal or account information via email.
- Always be skeptical of attachments. If you receive a message to view a file or video on a social networking site from someone within your network (a trusted source), it is still NOT safe to open the attachment. Criminals are avid fans of social networking sites. They hijack user accounts to send phishing invites to an account holder’s entire contact list, post poisoned links to a variety of malicious sites, and send credible emails with malicious links - abusing the trust that friends normally share. Some creative criminals have tailored messages to appear to come from the social networking site itself, designed so that users will divulge their login credentials or download a Trojan.
- Technology-based security measures such as firewalls, encryption, anti-virus, spam filters, and strong authentication will NOT prevent social engineering fraud. No matter how much security technology you implement, you can never get rid of the weakest link - the human factor. A social engineer is someone who uses deception, persuasion, and influence to get information that would otherwise be unavailable.
- If you receive an email from a friend or trusted source, it is NOT always safe to click on a link or attachment within that email. The email account of your friend or trusted source could have been compromised and is being sent to you by a criminal with the intent of getting information or to have you click a link or open an attachment. The email account of your friend or trusted source could have been compromised and is being sent to you by a criminal with the intent of getting information or to have you click a link or open an attachment.
- It is NOT always safe to click a link as long as the link is through a popular search site like Yahoo, Google or Bing. Search engine poisoning makes up 40% of malware delivery on the Web. The practice is when malware and spam attackers inundate search results with links to bait pages that will take users to malicious websites that will download malware to a computer. People want to be able to trust that what they search for in Google, Bing or Yahoo is safe to click on.
- Access web sites through your web browser. Typing the address of a web site directly into your Web browser will ensure that you are going to the legitimate Web site and not a phishing site that was designed to mimic the look of the real thing. Unless the site was hijacked or your computer has a virus, typing the web address yourself is the best way to guarantee the authenticity of a web site.
- Tech support scams are very popular. If you receive an e-mail from a Microsoft support person saying that your computer is infected by a virus and suggests that you install a tool available on their Internet site to eliminate the virus from your computer. You should NOT click on the link even though the email looks official and has the legitimate email@example.com email address. Email spoofing is e-mail activity in which the sender's address and other parts of the e-mail header are altered to appear as though the e-mail originated from a different source.
- Be skeptical when there are big news events happening. If you hear on the news that your insurance company has recently been breached and soon after you receive an email from your insurance company that explains the breach and provides the necessary steps for you to take. These steps include clicking on a link to update your personal information and change your username and password. You should NOT follow all instructions to keep your information protected. Now that the criminals have information about you, they may try to trick you into giving up more information through fraudulent emails. Be suspicious of urgent emails requesting information and never open attachments you aren’t expecting even if it’s from someone you know.
- If you are unsure about a link in your email, do NOT copy and paste the link in your web browser. You could still end up at the malicious site and potentially load malware on your computer or network. If you are unsure whether a link you received in an email is safe, it is not safe to copy and paste the link into the URL section of your web browser.
- If you are unsure about a link in your email, it is NOT safe to forward the link to have it tested by someone else. By forwarding an email, all you've done is forward a potentially dangerous and malicious email that could infect someone else's computer or network.
- Criminals could strike very quickly. For example, within hours of a hurricane, you receive an email from the Red Cross asking for a donation to help the victims. This email is most likely a high-profile phishing scam that receives media attention and is at the forefront of people's minds. These scams are effective because they rely on your emotions and compassion.
- Be aware of website extensions. For example, out of these six web addresses, "whitehouse.com" is phony because any official U.S. government website will end in .gov and not .com.
A brand-phishing email is designed to impersonate the official websites of prominent brands – such as those within the technology, banking, shipping, and retail industries. The purpose is to trick consumers into revealing sensitive personal account information. The email will contain malicious code that will redirect to a fake website (scam page) that requires consumers to log in to verify information. Links to these scam pages are sent through emails, text messages, or via web and mobile applications and may spoof the identity or online address to resemble the genuine site. The scam pages may then use login forms or malware to steal users’ credentials, payment details, or other personally identifiable information (PII).
- Desconfíe de los contactos no solicitados por correo electrónico o redes sociales de cualquier persona que no conozca personalmente y/o que contengan mensajes que le inciten a abrir un enlace o un archivo adjunto.
- Cuando reciba alertas de la cuenta, en lugar de hacer clic en un enlace dentro de un correo electrónico o texto, opte por navegar al sitio web utilizando la URL segura para revisar cualquier registro, mensaje o aviso.
- Closely verify the spelling of web addresses, websites, and email addresses that look trustworthy but may be imitations of legitimate websites, including the username and/or domain names/addresses (i.e., capital “I” vs small “L”, etc.).
- Utilice contraseñas únicas y seguras, y no reutilice la misma contraseña en varias cuentas.
- No almacene documentos o información importante en su cuenta de correo electrónico (por ejemplo, claves privadas de moneda digital, documentos con su número de seguridad social o fotocopias de un permiso de conducir).
- Habilite opciones de autenticación de dos factores o de varios factores para ayudar a proteger las cuentas en línea, como un número de teléfono, programas o aplicaciones de autenticación basados en software, una llave de seguridad USB o una cuenta de correo electrónico independiente (con una contraseña única que no esté vinculada a otras cuentas de consumidores) para recibir códigos de autenticación para iniciar sesión en la cuenta, restablecer la contraseña o actualizar la información sensible de la cuenta.
- Siempre que sea posible, no utilice su dirección de correo electrónico principal para iniciar sesión en los sitios web. Cree un nombre de usuario único no asociado a su dirección de correo electrónico principal.
Medios de comunicación social
- Desconfía de las invitaciones de las redes sociales. Si recibes un mensaje de un amigo en Facebook invitándote a unirte a una nueva red social, debes sospechar que el mensaje es fraudulento y ponerte en contacto con tu amigo para verificarlo. No te fíes de que un mensaje sea realmente de quien dice ser. Los piratas informáticos pueden entrar en las cuentas y enviar mensajes que parecen ser de tus amigos, pero no lo son.
- Do not allow access to your contacts. If you join a new social network and receive an offer to enter your email address and password to find out if your contacts are on the network, you should decline the offer and DO NOT allow the social network site access to your email address book. To avoid giving away email addresses of your friends, do not allow social networking services to scan your email address book. The site might use this information to send email messages to everyone in your contact list or even everyone you've ever sent an email message to with that email address. Social networking sites should explain that they're going to do this, but some do not.
- Social media sites can have infected links. For example, you receive an Instagram picture from a friend. It's a great picture so you decide to share it by clicking the Facebook "like" button underneath the image. This can be dangerous even if the picture came from a trusted source, it's a real Facebook button and you are not downloading anything. If you can see the picture, you could have downloaded Malware. If the Facebook "like" link was fake, you also could have inadvertently downloaded Malware. Malicious software (Malware) can be disguised as a Facebook "Like" button, picture or audio clip. When you click a link or open an attachment, malware installs on your device. Unlike early PC malware, it doesn't ask your permission, and your device is figuratively in the hands of a criminal.
- NO acepte una solicitud de conexión en las redes sociales de un desconocido sólo porque la persona parece honesta y conoce a otras personas que usted conoce. Sea selectivo a la hora de aceptar a un amigo en una red social. Los ladrones de identidad pueden crear perfiles falsos para obtener información de usted. Esa falta de precaución puede salir muy cara. La mayoría de las redes sociales contienen información personal. Cuando te haces amigo de alguien, le das acceso a esa información y eso puede ser utilizado por los estafadores.
- Borrar las fotos o los vídeos de las redes socialesNO los elimina permanentemente de Internet. Tienes que ponerte en contacto con el departamento de soporte de la red social para asegurarte de que se eliminan. Asume que todo lo que pones en una red social es permanente. Aunque puedas eliminar tu cuenta, cualquier persona en Internet puede imprimir fácilmente fotos o textos o guardar imágenes y vídeos en un ordenador.
- Puedes estar en riesgo incluso si descargas aplicaciones en sitios de redes sociales que parecen oficiales y el enlace de instalación de la aplicación está dentro del sitio de la red social. Ten cuidado con la instalación de extras en tu página. Muchos sitios de redes sociales te permiten descargar aplicaciones de terceros que te permiten hacer más cosas con tu página personal. Los delincuentes a veces utilizan estas aplicaciones para robar tu información personal. Para descargar y utilizar aplicaciones de terceros de forma segura, toma las mismas precauciones de seguridad que tomas con cualquier otro programa o archivo que descargues de la web. Modifica tu configuración para limitar la cantidad de información a la que pueden acceder las aplicaciones.
- Do not respond to social media requests. If you receive an e-mail requesting you to update your Facebook, Twitter, LinkedIn, eBay, or PayPal accounts, do NOT click on the link in the email, and DO NOT LOGIN and update your account as requested. Before writing your username and password look at the web address in the browser. The fake ones look similar to this: http://k2nxw.com/cgi-bin/login/ or www.paypal5281.com. If you are not sure, log into your real account just like you usually do, by typing the web address in the browser by yourself and not using the links provided.
Qué no compartir en las redes sociales
- Know what you've posted about yourself. A common way that hackers break into financial or other accounts is by clicking the "Forgot your password?" link on the account login page. To break into your account, they search for the answers to your security questions, such as your birthday, hometown, high school class, or mother's middle name. If the site allows, make up your own password questions, and don't draw them from material anyone could find with a quick search.
- Think twice before sharing personal information that would make you vulnerable. Social networking means opening up and sharing information online with others, but there's some information you should never share online. Protecting yourself from sharing Too Much Information (TMI) can save you from identity theft and even protect your physical safety. So let's start with the obvious - never share your social security number (including even just the last 4 digits), your birth date, home address, or home phone number (although sharing your business phone is ok ). Of course, you should protect all of your passwords, PIN numbers, bank account, and credit card information and never share the state where you were born as this information can be used to obtain your social security number and other identifying information.
- Los mensajes sobre la salida de la ciudad pueden hacer que su casa sea susceptible de ser robada.
- Fotos y vídeos de su casa, coche y otras posesiones personales.
- Personal information, including your Social Security number (not even the last four digits), birthday, the name of your high school, your pet's name, your place of birth, home address, phone numbers, or personal account information.
- Evita publicar una foto tuya de frente en las redes sociales. Un estafador puede copiar la imagen y utilizarla para crear una foto de identificación que puede ser utilizada para robar su identidad.
- En caso de duda, no publiques nada. Compartir en exceso puede dar a los delincuentes la información que necesitan para hacer ingeniería social para que caigas en una estafa.
- Asume que todo lo que pones en una red social es permanente. Aunque puedas borrar tu cuenta, cualquiera en Internet puede imprimir fácilmente fotos o textos o guardar imágenes y vídeos en un ordenador.
- Limita los detalles del historial laboral en LinkedIn: Si crees que necesitas la información añadida para ayudarte en la búsqueda de empleo, amplía los detalles durante el proceso de búsqueda de empleo y recórtalos más tarde, una vez que tengas un puesto, dejando sólo la información suficiente para atraer a los reclutadores para que se pongan en contacto contigo con nuevos puestos interesantes. LinkedIn también ofrece algunas posibilidades para restringir la información. Puedes cerrar el acceso de otros a tu red de contactos, algo que no tienes que compartir si no quieres.
- Avoid accidentally sharing personal details. Social networking sites make it easy to let details slip you wouldn't otherwise tell friends or strangers. Be aware of what information you put out there that others might use for nefarious purposes.
