Stop Credential Stuffing Attacks OnlineStop Credential Stuffing Attacks Online

With remote work and social media, users have more accounts, platforms and login credentials to remember. As a result, hackers can find and reuse compromised credentials to gain access and perpetrate attacks on a large scale. The threat is fueled by the availability of leaked passwords and hacking tools for sale on the Dark Web. Attackers can scour the Dark Web and underground forums for databases of stolen usernames and passwords, then use automated software to attempt a barrage of login attempts on targeted websites and applications.

Successful logins give attackers access to a user’s account and personal information, as well as other downstream opportunities such as e-commerce fraud or identity theft. For example, video streaming service Netflix fell victim to a credential stuffing attack in 2019, with hackers using breached data and crimeware to steal users’ passwords. Nintendo’s user database also fell prey to a similar attack in 2020.

Stop Credential Stuffing Attacks Online: Prevent Unauthorized Logins

Stop credential stuffing attacks online is that credential stuffing can be stopped with the right cybersecurity measures. These include monitoring for leaked credentials on the Dark Web and other underground forums, enforcing strong password policies with length requirements, requiring unique logins per website or account, and enabling security features such as multi-factor authentication (MFA).

In addition to these preventative strategies, organizations should systematically review fraud case volume over time to identify spikes that may indicate an attack, as well as set clear lines of communication between customer service and information security teams. To protect against unauthorized logins, companies should also deploy devices such as Arkose Labs’ zero trust privileged access management solution (PAM), which screens the devices that connect to the network and blocks credentials from known bad actors, all without disrupting the user experience.…

How to Use an Email Checker Tool to Validate Your Email AddressesHow to Use an Email Checker Tool to Validate Your Email Addresses

A reliable email checker tool (also known as an email validator, email scrubber or email list cleaner) scans your marketing emails to ensure that the addresses they’re heading to exist and are able to receive messages. This plays a vital role in maintaining the quality of your lists, improving email deliverability rates, protecting your sender reputation and ultimately boosting your email marketing ROI.

A good email verification service will do more than just make sure the syntax of an address is correct – it will also detect if an address is a disposable or temporary email, which is frequently used by hackers and scammers. Additionally, it will conduct a full domain verification and mailbox validation by connecting to the mail server over SMTP and simulating sending a message to verify that the mailbox exists and is capable of receiving messages.

Email Checker Tool: The Key to Error-Free Email Campaigns

The best email verification software will also identify old or unused addresses that have become spam traps, which are designed to catch companies that are sending unsolicited emails. You can then manually identify and remove these addresses from your list, preventing them from impacting your deliverability rates or being reported as spam.

A real-time email checker will qualify new emails as soon as they’re entered into your data collection forms, ensuring that your lists are of high quality from the start. This prevents spammers and spoofers from taking advantage of your inexperience with email validation and saves you the time and expense of dealing with bounced emails, lost revenue, and possible suspension from your email provider.…

Email Verification Tool is the process of identifying and removing non-existent, invalid or inaccurate email addresses from your contact database to improve the quality of your list and minimize bounce rates, an important metric that affects overall email deliverability. Email verification is an essential step in any marketing campaign as it helps you avoid the negative impact of a high bounce rate by only sending emails to valid recipients.

Invalid or non-existent email addresses are a major cause of hard bounces, which in turn negatively affect your deliverability metrics and can even damage your sender reputation with email service providers (ESPs). Email validation can significantly reduce your bounce rates by focusing your campaigns on verified and accurate email address lists, thus saving you time and resources that would be wasted on ineffective email communications.

“Is an Email Legitimate? How to Check for Scams

How to Block a Malicious IP AddressHow to Block a Malicious IP Address

 

A malicious IP address appears to be a harmless string of numbers, but it can actually reveal valuable information about your device and location. Attackers use this to target you with malware, phishing attacks or scams. The IP can also serve as a channel to the attacker’s command-and-control server.

Malicious IPs aren’t always blacklisted, which makes it difficult for firewalls and other cybersecurity solutions to block them effectively. Some of the challenges include:

Often, malicious IP addresses have low popularity – meaning they don’t get much traffic compared to well-known IPs. As such, they tend to blend in with legitimate sources and may be ignored by security tools.

Malicious IP Address Lookup: Protecting Your Network from Threats

Another challenge is detecting suspicious activity from dynamic IPs that change periodically. This can be due to a lack of visibility on the cloud or when an IT department changes an employee’s assigned IP address.

To solve this challenge, it’s essential to incorporate tracking and multiple threat intelligence sources when assessing an IP’s reputation. Additionally, analyzing the DNS lookup name and destination port can provide valuable insights into the IP’s behavior. For example, an empty DNS name or the use of destination ports commonly used for phishing or spam can flag a malicious IP.

Using machine learning to identify malicious or suspicious IPs helps to fortify networks and systems against threats. For example, Voros’ research on Sophos AI visualized clusters of malicious activity across the IP space based on physical infrastructure, which allowed for detection of never-before-seen IPs.…

How to Protect Your Website From Fake Sign UpHow to Protect Your Website From Fake Sign Up

Fake sign up  is a serious problem for digital businesses. It can affect deliverability rates, skew audience data and cost businesses a lot of money.

It happens when bad actors use bots to fill out forms on your website with fake information, and it is a growing problem for many e-commerce platforms and other online services. They may do this for a number of reasons, from obtaining freebies and stealing user data to damaging your reputation and hurting business operations.

Seeds of Success: Strategies for Secure and Efficient New Account Origination

Most digital businesses request only a few pieces of personal information when new users register, such as a name and email address, which makes it easy for bad actors to create fake account registrations. This leniency is often exploited by spambots that are programmed to look for specific code and then fill out the form with fake information.

A sign that your audience data is skewed by fake sign up is when the first and last names provided don’t match the email address. Another sign is when there are many sign ups from a single geographic location all of a sudden, as this could be a spambot attack.

To protect your business against fake sign up, there are a few techniques you can use, such as rate limiting. This method prevents too many form submissions from a single IP address or device in a short period of time and is effective at blocking spambots. You can also implement a honey pot field, which is a hidden field that will only show up when the spambot fills out the form, letting you know it’s an attempted scam.
