Phishing leads to other Attacks#

Phishing is often just the entry point to more attacks. For example, To obtain a perform such attacks like pass-the-hash or pass-the-ticket, the attacker needs credentials of a user to get in the door.

Phishing Example#

One trick that bad guys use a lot is called CEO Fraud. CEO Fraud involves a scam in which cybercriminals impersonate executives in order to fool an employee into executing unauthorized wire transfers, or sending out confidential Sensitive Data. A sense of urgency is usually employed, pressuring the victim to act before thinking. According to FBI statistics, CEO fraud is now a $12 billion scam.

Spear-Phishing#

Where general email attacks use spam-like tactics to blast thousands at a time, spear phishing attacks target specific individuals within an organization. In this type of scam, hackers customize their emails with the target’s name, title, work phone number, and other information in order to trick the recipient into believing that the sender somehow knows them personally or professionally. Spear phishing is for organizations with the resources to research and implement this more sophisticated form of attack.

2. Whaling#

Whaling is a variant of spear phishing that targets CEOs and other executives ("whales"). As such individuals typically have unfettered access to sensitive corporate data, the risk-reward is dramatically higher. Whaling is for advanced criminal organizations that have the resources to execute this form of attack.

3. BEC (Business Email Compromise)#

BEC attacks are designed to impersonate senior executives and trick employees, customers, or vendors into wiring payments for goods or services to alternate bank accounts. According to the FBI's 2019 Internet Crime Report,  BEC scams were the most damaging and effective  type of cyber crime in 2019.

4. Clone Phishing#

In this type of attack, the scammer creates an almost-identical replica of an authentic email, such as an alert one might receive from one's bank, in order to trick a victim into sharing valuable information. The attacker swaps out what appears to be an authentic link or attachment in the original email with a malicious one. The email is often sent from an address that resembles that of the original sender, making it harder to spot.

5. Vishing#

Also known as Voice phishing, in vishing, the scammer fraudulently displays the real telephone number of a well-known, trusted organization, such as a bank or the IRS, on the victim’s caller ID in order to entice the recipient to answer the call. The scammer then impersonates an executive or official and uses social engineering or intimidation tactics to demand payment of money purportedly owed to that organization. Vishing can also include sending out voicemail messages that ask the victim to call back a number; when the victim does so, the victim is tricked into entering his or her personal information or account details.

6. Snowshoeing#

In a snowshoeing scheme, attackers attempt to circumvent traditional email spam filters. They do this by pushing out messages via multiple domains and IP addresses, sending out such a low volume of messages that reputation- or volume-based spam filtering technologies can’t recognize and block malicious messages right away. Some of the messages make it to the email inboxes before the filters learn to block them.
