How common is spear phishing
How does spear phishing work? As a result, they're becoming more difficult to detect. The shutting down of the warez scene on AOL caused most phishers to leave the service. That slip-up enables cybercriminals to steal the data they need in order to attack their networks. These cybercriminals employ individually designed approaches and social engineering techniques to effectively personalize messages and websites. Spear phishing emails, on the other hand, are more challenging to detect because they appear to come from sources close to the target. Along with standard controls such as spam filters, malware detection and antivirus, companies should consider phishing simulation tests, user education, and having an established process for users to report suspicious emails to the IT security team.
The attackers then disguise themselves as a trustworthy friend or entity to acquire sensitive information, typically through email or other online messaging. A whaling attack is a spear-phishing attack directed specifically at high-profile targets like C-level executives, politicians and celebrities.
Security teams can create and present their own training materials, or purchase training materials from vendors. In an enterprise, security awareness training for employees and executives alike can help reduce the likelihood of a user falling for spear phishing emails.

A popup window from Facebook will ask whether the victim would like to authorize the app. As a result, even high-ranking targets within organizations, like top executives, can find themselves opening emails they thought were safe. The more personal information is present in an email, the more likely a victim is to believe that the email is authentic. Phishing Phishing involves sending malicious emails from supposed trusted sources to as many people as possible, assuming a low response rate. A more common example is attackers pretending to be suppliers and requesting a change in invoicing details. Spear phishing attackers perform reconnaissance methods before launching their attacks. One example of such a policy is to instruct employees to always enter a false password when accessing a link provided by email. Criminals select an individual target within an organization, using social media and other public information—and craft a fake email tailored for that person. How much personal information is available for potential attackers to view? Because of the personal level of these emails, it is more difficult to identify spear-phishing attacks than to identify phishing attacks conducted at a wide scale.
