FREMONT, CA: Phishing attacks are on the rise across every sector. As the attacks become more ingenious every day, it is difficult to counter them and secure the integrity of the organizations. The standard attacks targeted at cloud services are manifold, including ransomware, spear phishing, SQL injection, cross-site scripting, spyware, insider threats, and such.

However, phishing is one of the most common challenges faced by businesses. The attackers gain access to sensitive business data, financial records, and employee information. Phishing attacks can affect both locally and remotely managed network infrastructures. Cybercriminals leverage email messages as attack vectors, utilizing collaborative technologies such as SMS messaging, shared workspaces, and social media.

Previously, attackers sent mass emails to catch victims off guard and have them download malicious attachments and divulge sensitive information. However, the recent trends show an increase in spear phishing, which involves targeting specific individuals or groups in the organization.

It is imperative for organizations to secure their infrastructures through proper incident response. It involves forming policies, practices, and teams that can take immediate action in case of such attacks. Even though the primary purpose of incident response is to mitigate the damage, it can also help to prevent the occurrence of phishing attacks.

The first step in incident response involves training the employees to identify fraudulent emails aimed at harvesting business data. The emails can be determined by details such as the email address, subject line, topic, style of writing, presence of unsolicited attachments and suspicious links, and so on. It is also advisable to set up separate and isolated workstations to determine the validity of emails before forwarding them to the recipients.

The security team can classify the phishing attacks according to their severity levels, assigning appropriate priority levels. It can prioritize unique attacks and notify the employees to keep a lookout for similar emails. The phishing emails have to be examined and assessed as well to determine their impact on the organization.

Businesses need to take concrete steps to mitigate the damage to the business processes and immediately close off the doors for potential attacks. Changing the login credentials of the affected accounts is advisable. Educating the employees regarding the mechanisms of phishing attacks is crucial, and will play a significant role in eliminating the possibility of similar attacks.
