Understanding The Cyber Threat Types And Safeguards For Phishing, Vishing, Smishing, And Pharming

The global wave of cybercrime has risen to the level of a tsunami. Individuals, small and big businesses, and even governments are being targeted by cybercriminals who are continually updating conventional threats. They’re using the development of remote work situations, as well as the proliferation of smart gadgets, to draw victims into their phishing schemes.

From 2019 to 2020, the FBI claimed that almost 800,000 cyber crime complaints resulted in more than $4.2 billion in damages. Unfortunately, it is expected that future cyber assaults will demonstrate that unscrupulous actors are capable of creating an even greater impression with illicit phishing operations.

What is phishing? 

This is most likely the approach used by hackers. It entails sending misleading emails that direct users to a bogus website that seems to be their bank’s. This may also happen on Facebook, where bogus fan pages publish false content and solicit sensitive information from individuals.

Phishing fraudsters commonly employ bogus campaigns to update client data or to entice customers to enter a bogus contest held by the bank. Fraudulent websites solicit information such as IDs, online banking passwords, credit card details, and even the security code, which fraudsters use to make online purchases without the customer’s knowledge.

The first line of defense against phishing is to avoid providing private information. If you are already a customer of the bank, the financial institution will never send you an email asking for this information. Banks never send emails with subject lines like “you won a reward” or “unblock your account.” Finally, if you do click on the link, always check the website’s URL. It should have a lock icon before the name and begin with “HTTPS.”

What is Vishing?

Vishing (voice+phishing) is a type of phishing that also employs social engineering techniques, but with the assistance of a phone call.

This is how most attackers, dubbed “vishers,” behave:

For example, the user receives a phone call from a bank employee, and the operator informs him that his banking card will be stopped if the entire information about the card, including its number, CVV-code, and so on, is not supplied by phone right now. Hearing such a ‘threat,’ a trusting customer panics and divulges all personal information up to and including the verification code.

During a vishing attempt, the user may be promised a big discount on a purchase or notified of a lottery win. It is pointless to enjoy such a discount or such an attractive award unless you double-check the facts given by referring to official sites.

As a result, it is critical to remember to double-check everything. It is well worth saying goodbye gently to the person on the other end and checking the offered information with a call to the bank’s hotline; they will supply you with more accurate information.

The most important thing to remember in any uncertain scenario is not to panic. Remember that you can always double-check everything. Say goodbye politely to the person you’re speaking with and contact the hotline of the organization to which the caller addressed himself. So you can simply determine whether the call was genuine or whether you were a victim of vishing.

What is SMIShing?

SMiShing is another sort of phishing assault that uses bogus SMS messages to mislead unsuspecting victims into handing over critical information. This type of phishing is less widespread in the corporate sector than spear phishing and vishing, but it may become more of a problem as the usage of bring-your-own-device (BYOD) in the workplace increases.

In general, SMiShing attempts follow one of two patterns:

  • The attacker persuades their target to open a URL supplied by text message. The URL then redirects users to a false credential logging page or a download page where malware is installed on the user’s device.
  • Regarding the message’s content, the attacker advises the victim to phone a certain number. These calls either result in the attacker seeking sensitive information over the phone, as seen in a vishing attempt, or they are to a premium rate phone line, resulting in a large phone bill for the user.

In the case of SMiShing, attackers typically imitate brands to acquire the trust of their victims. According to Check Point, Microsoft is the most impersonated brand in the world, accounting for 43% of brand phishing attempts, followed by DHL (18%) and LinkedIn (6%). With more people than ever relying on Microsoft’s cloud apps to build a virtual office, it’s simple to see why attackers are taking advantage of their brand.

What is Pharming?

Pharming assaults, like phishing emails, deceive users into disclosing personal information. Email communications, however, are not required in a pharming assault. Malicious code is installed on a computer or server by cyber attackers and can be used to redirect users to a fraudulent website.

Pharming examples include:

  • Malware-based: Corrupted files, whether sent by email or downloaded, can drive a computer to fraudulent sites regardless of the intended destination.
  • DNS server poisoning: A tainted DNS server can redirect network traffic involving possibly millions of users to a bogus IP address.

Why is pharming profitable for hackers?

Aside from the initial execution of the virus, the user is not required to click anything that appears suspicious. Once the malware has been loaded and run, it remains on the computer – even after it has been restarted. Only malware removal software can clear files that are used to track user behavior, display popups, or hijack browser settings.

How To Safeguard from these Phishing Attacks?

The greatest and most effective first step is to keep your cyber security guard up. Assume your organization’s network is susceptible, and that cybercriminals have your address on their radar. General, preventative actions like staff training, continuous network monitoring, and consistent communication throughout the business may thus assist not only limit risk but also put a strategy in place to rapidly and effectively recover from a phishing cyber assault.

The threat of phishing attempts is real, and it necessitates constant care and attention. Protect your vital information — and your reputation. Contact Dean Dorton immediately to schedule a cyber security risk assessment or audit.

So, what’s the distinction between phishing, vishing, smishing, and pharming – these seemingly similar but distinct sorts of Internet fraud? The common purpose for all of them is to get private information, mostly via sending people to bogus websites. However, this is done in a variety of ways:

  • Email is used in phishing.
  • Vishing – through phone call
  • SMS is used in smishing.
  • In pharming, this is accomplished by using the DNS cache on the end user device or the provider’s network infrastructure.

How can you defend yourself from phishing, vishing, smishing, and pharming? Use trusted browsers and antiviruses, enable two-factor authentication, don’t trust every initial caller, and constantly double-check the information.
