Educating your business on the importance of cybersecurity

Should Your Organization Hire a vCISO?

Posted by ProCircular Team on Jun 1, 2021 10:58:25 AM

Technology is essential to modern business operations, but cybersecurity risks and data exposure threats come with that. Thankfully, a virtual chief information security officer (vCISO) can bring comprehensive strategic and operational leadership to security for companies that can only afford a part-time person in an executive cybersecurity role. Amid today’s industry-wide shortage of skilled security workers, vCISO could be the best option for finding and retaining critical security leadership.

How to Spot and Stop Today's Malicious Emails

Posted by ProCircular Team on May 3, 2021 9:35:29 AM
Phishing Attacks
During a phishing attack , attackers use social engineering and malicious emails to steal valid credentials from users. Attackers can use these credentials to begin more complicated attacks, or they can bundle and sell them to other cybercriminals . The attacker s lie about their identity and objectives to collect login information from unassuming victims or to get them to download malicious content . These emails might ask you to enter your password into a spoofed login page or send that information directly back to the sender . Although these scams are well - known, they are occasionally hard to spot, and they have a high rate of success . If you don’t encounter many of these emails, they may be caught in your junk folder. If this is the case, your email filtering is working effectively and removing potentially harmful phishing attempts. There is no reason to recover phishing emails from a junk folder.
 
Extortion Attacks
Extortion emails work a little differently . In this increasingly popular type of attack, the hackers claim to already have access to some sensitive information. That information could include anything from login credentials to embarrass ing photo s. Whatever they choose is something designed to prompt an urgent and desperate reaction from the recipient. In the email, they lay out what they have against their target, then threaten to blackmail them for money.
These types of emails are des igned to be scary. They are supposed to make the victim feel so frantic that they act without thinking. If you ever receive a threatening extortion email, remain calm and report it t hrough the proper channels. In this post, we’ll break down a poorly writte n extortion email that was sent to my junk folder.

Security information and event management, or “SIEM,” is a tool that assimilates all of your log data to give you an all-encompassing overview of the activity on your network. SIEM tools watch over your network and help you stop trouble in its tracks. Whether your organization has 200 or 20,000 employees, SIEM software can be a vital part of any company’s cybersecurity posture.

Using an Interactive Cross-site Scripting Backdoor

Posted by Bill Thomas on Feb 26, 2021 3:29:48 PM

As a cybersecurity engineer and an unapologetically enthusiastic “web guy,” I have both a personal and professional interest in finding new exploitation methods. Recently, I found an interesting and creative way to control a browser by exploiting a cross-site scripting (XSS) vulnerability. I learn by doing, so I executed the concept to see it work in practice. Without spoiling too much, I was very pleased with the results! This attack uses nothing more than Netcat and some clever XSS injection code. For those unfamiliar with Netcat, it’s a networking utility that reads and writes data across network connections.

Secure Remote Connections with SSH

Posted by Mike Hedlund on Jan 11, 2021 11:36:23 AM

In today’s fast-paced and remote workforce, establishing a secure remote connection is critical to conduct safe and efficient remote work. Securing this connection can be as simple as creating a jump box to access a network or device. This method allows for secure external access to internal resources without using custom firewall rules. Although there are several ways to initiate this connection, the one we’ll discuss here uses a reverse SSH tunnel through a jump box. The reverse connection process is more secure than the standard connection process, and it is the preferred option for connecting to sensitive remote devices.
