Spam filters are a great way to protect yourself from unwanted emails (or phone calls in the case of robocalls). But what exactly makes a spam filter work?
Spam filters identify unsolicited, unsolicited, and virus-infected email (known as spam) and prevent it from getting into email addresses. Internet-service providers (ISPs) and small and medium-sized businesses (SMBs) use spam filters to make sure that they aren’t distributing it.
Both incoming and outgoing email are sent to the filtering process. Spam filters are utilised by ISPs to protect users. Small businesses typically target inbound filters.
One of the more popular and controversial email marketing techniques these days is DKIM. While it’s not entirely a new method, DKIM (DomainKeys Identified Mail) is quickly gaining in popularity and may be becoming more necessary in the digital age. DKIM is an email authentication tool that verifies the authenticity of an email. It works by sending DKIM information from an email to a server, which checks that information against public DKIM records before it accepts the message.
This article provides an overview of the joint Cybersecurity Advisory (CSA) issued by the Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), and the Department of the Treasury (Treasury) on the Maui ransomware, which has been used by North Korean state-sponsored cyber actors to attack Healthcare and Public Health (HPH) Sector organizations.
In this fast-paced world where things change overnight, ensuring cybersecurity is a rather challenging task. While adversaries are constantly looking for avenues to exfiltrate data and compromise systems, our goal is to ensure the security of our information systems. The following cyber news headlines aid in this process of understanding cybersecurity better and protecting our systems:
The current situation of OT products has revealed a tough spot, highlighting 56 vulnerabilities. With over ten vendors, including the likes of Siemens, Emerson, Honeywell, and more, the latest vulnerabilities in various popular protocols and products have certainly provided a new perspective.
These days, cyber-attacks involve more than the obvious malicious link sent to you through a phishing email. You must remain alert, especially against cryptocurrency scams, as they continue to rise. Here are this week’s cyber headlines:
Technology conglomerate Cisco suffered a significant vulnerability. The latest Cisco vulnerability, discovered on June 6, 2022, allowed cybercriminals to crash the Cisco Secure Email appliances remotely via the usage of malicious email messages.
The Cisco high-profilevulnerability, the CVE-2022-20798, could allow cybercriminals to cut the affected device from management interfaces, rendering them unreachable and causing a DoS (Denial of Service). Let us look at the Cisco vulnerability that has caused a serious commotion.
Microsoft is an organization that provides services across the globe, with over 1.4 billion existing users. With many such users and a huge array of services being provided, there is a high chance of security issues. The zero-day vulnerability that cyber attackers nicknamed “DogWalk” has become an enormous concern for Microsoft as there is no official patch available for it yet, and the extent of compromise using the vulnerability is unclear.

Cyberattacks are a constant problem but can be tackled with the right cybersecurity measures. This week’s news headlines feature one such incident, reemphasizing the significance of being vigilant online.
The Internet is a vast place. It is estimated that there areclose to 2 billion websites online in 2022. Each of these websites has a unique hostname, or ‘domain’, that can be resolved into an IP address.
Whilst anyone can access these websites, one should note that some domains are more ‘valuable’ than others. Domains that include relevant keywords are more likely to show at the top of search engine results, directing more traffic to those sites. For example, a Google search for “how to make a voicemail” may direct you to websites with the word ‘voicemail’ in the domain name.
