What is Phishing?
This varies from the specific type of phishing, but in general, phishing is the act of tricking and manipulating a user to reveal information to the attacker through various means.
Tools of the trade can range from malware laced documents, to websites with URLs that are spelled similarly to popular services that steal login credentials, known as Typo Squatting.
Who gets targeted?
Usually, phishing attacks happen by chance, as they are mass mailed to hundreds of emails at a time, but there are targeted campaigns as well. Spear phishing attempts come in to play when the attacker identifies that a user has roles/privileges in the organization that others don’t, which may assist them in spreading to other users.
There also exists the “whaling” attack, which targets the owner of an organization. Typically, they will have the highest level of access to all resources in the business, ranging from the business’s internal networks, bank accounts, and potentially even other client’s networks.
Why?
As computer security is coming into focus, and as anti-malware software continuously starts offering better protection, phishing is becoming more and more commonplace for all types of attacks, ranging from Identity Theft to Espionage.
With the increased focus on computer security, malicious users have become more creative with their attacks, resulting in higher success rates with more infections and intrusions. Even in the face of employee training, successful attack rates have been high.
Phishing offers a quieter approach throughout the attack process, as people may not notice what has happened by the time they enter their information, or open an attached document. Assuming the user catches the misspelled URL, or realizes the document they opened is fake, they may be afraid to report the issue, fearing repercussion. Combining all these factors leads to the perfect platform for carrying out a very successful attack campaign.
What can be done to prevent phishing attacks?
- Ensure that your email system has a spam filtering system in place.
- Offer plenty of resources to help your employees identify phishing attempts. Teaching them to identify URLs by moving their cursor over links, for example, will greatly reduce successful attempts.
- Verify that proper anti-malware software is in place and up to date. This will help reduce infections from malicious documents.
- Let your employees know they shouldn’t be afraid of reporting any phishing attack they may have fell victim to.
- Teach Employees that they are never to open attachments from unknown senders, and to scan attachments from senders they may know but were not expecting.
- Read through the body of the email to ensure there are no spelling mistakes, as your everyday mass mailed phishing attack will commonly carry many errors.
- Have email scanning software in place that removes malicious attachments before they arrive in the user’s inbox.
- If your business uses any type of portal that employees access, remind them of the correct location periodically, and to verify that the URL they’re accessing is correct if they ever receive an unknown email telling them to update their password.
