Part 01 link: Overview of Phishing Attacks - Part-01
What damage can phishing cause to an organization?
Phishing takes advantage of the human element to get beyond technological security measures. Technical security safeguards could be rendered worthless if this attack approach is used. Attackers may use spear-phishing assaults to acquire access to an organization's systems while the organization is uninformed.
The virus used in these attacks allows the attackers to take control of the victim's computer. This permits an attacker from the outside to get remote access to the inside network.
In addition, attackers frequently gain access to users' credentials as a result of attacks. Access to restricted systems or data is possible with these credentials. Many technological security protections can be bypassed using privileged access from compromised computers or credentials to an organization's systems. Assailants may be able to pivot and escalate their access to other systems and data as a result of this. In the end, this might lead to an organization's total compromise. This could include data theft from customers and employees, source code leaks, website defacing, and so forth.
How can you prevent being a victim of phishing?
The security posture of a company is determined by how well it defends itself against phishing assaults. Spam filters (or another type of intrusion detection system (IDS)) should block fraudulent emails, anti-virus software should block malware, and the outbound firewall should block contact with the attacker at the very least.
Properly configured domains and user accounts considerably minimize the extent to which an attacker can access an organization if these safeguards fail (or are non-existent). Social engineering awareness training should be a company-wide necessity because phishing targets the human component.
There is no such thing as a "one-size-fits-all" solution. An organization's protection systems must be tailored to their specific business needs. Many businesses begin with a red team security assessment to identify areas that need to be improved. A red team assessment uses social engineering tactics to simulate a realistic attack situation. Assessors can then recommend targeted mitigation strategies to improve the organization's security posture once the assessment is completed.
Both consumers and businesses must take precautions to protect themselves from phishing attacks.
Vigilance is essential for users. Spoof communication frequently contains inconsequential errors that reveal its genuine identity. As demonstrated in the previous URL example, these can include typographical errors or domain name modifications. Users should also consider why they are receiving such an email in the first place.
Enterprises can take a number of precautions to protect themselves from phishing and spear-phishing attacks, including:
Two-factor authentication (2FA), which adds an extra layer of verification when entering into critical applications, is the most effective way for preventing phishing attempts. Users need two things to use 2FA: something they know, like a password and user name, and something they have, like their smartphones. Even if an employee's credentials have been compromised, 2FA stops them from using them to obtain access since they are insufficient.
Organizations should enforce strong password management rules in addition to using 2FA. Employees should be compelled to update their passwords on a regular basis and should not be permitted to reuse the same password for different applications.
By enforcing secure behaviors like not clicking on external email links, educational efforts can help reduce the threat of phishing attempts.
