Phishing Attacks

Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. This kind of attack can have devastating results for individuals and organizations – the repercussions includes unauthorized purchases, the stealing of funds and information theft.

It can occur when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, text message or even a call. See below the most common types of phishing attacks:


EMAIL PHISHING – most common one

Sent by email. The criminal will register a fake domain that mimics a genuine organization and sends thousands out thousands of generic requests. The fake domain often involves character substitution, like using ‘r’ and ‘n’ next to each other to create ‘rn’ instead of ‘m’ or use the organization’s name in the local part of the email address (such as paypal@domainregistrar.com) in the hopes that the sender’s name will simply appear as ‘PayPal’ in the recipient’s inbox.


SPEAR PHISHING

This is a more targeted type of attack, criminals who do this will already have some or all the following information about the victim: their name; place of employment; job title; email address; and specific information about their job role.

One of the most famous data breaches in recent history was the hacking of the Democratic National Committee, conducted with the help of spear phishing. The first attack sent emails containing malicious attachments to more than 1,000 email addresses. Its success led to another campaign that tricked members of the committee into sharing their passwords.


WHALING

Whaling attacks are even more targeted, taking aim at senior executives. This one has the same goal as any other kind of phishing attack, the difference is that the technique tends to be a lot subtler. Tricks such as fake links and malicious URLs are not useful in this instance, as criminals are attempting to imitate senior staff to trick people into their scams.


SMISHING AND VISHING

In this type telephones replace emails as the method of communication. Smishing involves criminals sending text messages, where the content of it is much the same as the email phishing, and vishing involves a telephone conversation. A common vishing scam involves a criminal posing as a fraud investigator, either from the card company or the bank telling the victim that their account has been breached. The criminal will then ask the victim to provide payment card details to verify their identity or to transfer money into a ‘secure’ account – by which they mean the criminal’s account.


ANGLER PHISHING – most recent

This is a more modern kind of attack as it uses social media for it. Social media offers several ways for criminals to trick people: Fake URLs; cloned websites, posts, and tweets; and instant messaging – essentially the same as Smishing – All can be used to persuade people to disclose sensitive information or download malware. Also, criminals can use the data that people willingly post on social media to create highly targeted attacks.

In 2016, thousands of Facebook users received messages telling them they’d been mentioned in a post. The message had been initiated by criminals and unleashed a two-stage attack. The first stage downloaded a Trojan containing a malicious Chrome browser extension on to the user’s computer. When the user next logged into Facebook using the compromised browser, the criminal was able to hijack the user’s account and were able to change privacy settings, steal data and spread the infection through the victim’s Facebook friends.
