A bot is a software application that is programmed typically to do some of the human's repetitive tasks at a much faster speed. One good thing about bots is it's automated. Which means they can run according to the programmed instructions and doesn't necessarily require human intervention.
Based on usage and behaviour, bots can be:
In this tutorial, you will be learning the A-Z of SPAM Bots and ways to catch hold them at the early stage to minimize the losses.
Before I start with Spambots, let's discuss a few points briefly about bad bots. In this era, you are interacting more with a bot than a human no matter its a robocall from any telecom industry or chatbots. Unless these bots are not causing harm, you are happy to interact with them. But;
40% of the global internet traffic is bots consisting of both good and bad ones. The worst affected industry is Banking & Finance, where 42% of the traffic is of bad bots. These bots directly gain profit by scraping or collecting sensitive data through phishing pages or similar techniques.
The next most affected industry is ticketing, where 39% of the web traffic is of bad bots. These bots purchase tickets in real-time and sell to the third party, which directly affects the genuine customers.
Based on the type of activity and intent, bad bots can be further classified. Spambot has been the most known bad bots on the internet.
A spambot is a software application that is programmed typically to distribute bulk spam messages to users. Spambots are capable of doing various malicious activities which include things like fake commenting on forums, collecting email addresses, showing irrelevant ads. These spambots send unwanted messages which generally have phishing links or forms to get your data. Few spambots work on spreading false promotions to increase false traffic on websites.
Spambots can operate on various mediums with different methods. It can create accounts on different sites, comment on social groups, forums, and communities with irrelevant information. These bots are programmed capable enough to interact with users like a human on different forums and communities.
Signup forms consist of few data fields, and any hacker can write a small script or code to program bots in such a way that it can fill the form. Using such bots, they do multiple vague signups that flood up the organization database with spam accounts. Due to this irrelevant signup, the genuine user faces the latency while interacting on websites and the possibilities of getting higher bounce rates on the signup form increases. These spambots can gain access to your platform and can initiate unwanted spam to other users.
Few spambots are just programmed to scrap the data from all over the internet. And, then sell the data on the dark web. These data may include sensitive financial information and other PII information like email address, phone number, and social accounts.
Based on the kind of activity, Spambots can be of different types. Like a few scrap data, some spam on the comment section of websites, some send an unwanted message through emails.
These bots collect emails by crawling web pages by matching pattern, like [email protected]. Once the data is harvested by scraping, and email database is ready. The attackers send out emails to large no of users. These emails are malicious in nature consists of malware or have some link which leads to collect your personal information (phishing).
Email Spam is not only done on the harvested database but also includes the email list purchased from the dark web.
Email Spam is not only done on the harvested database but also includes the email list purchased from the dark web.
Comment spam is a bot generally found in different open forums. These bots typically initiate fake comments to sell a product or to generate backlinks to increase website traffic. Many websites allow public commenting which makes it easier for spambots to comments without even having an account with the website. Even if your platform requires an auth, these bots can create an account and start commenting.
The most active bots are on social media like Twitter, Facebook or Instagram. These bots typically post messages with offers, deals, and products. They will like, share and comment on the post which is not at all relevant to connecting posts. The accounts can be a fake account or a real user whose account is compromised. Their account will look legitimate like any other real account. Usually, you can find the number of twitter bot who are tweeting, retweeting and liking the post which satisfies their set of rules. To get a demo how bots work click here: Golang bot (this bot retweet any tweet with #Golang)
These spambots typically abuse on signup forms and subscription forms. Spambots exploit these fields by submitting thousands of email addresses which don't belong to anyone.
There are some cool techniques to avoid such abuses:
The best and probably the simplest method one can use to avoid spam and abuse on the website. It is a great of handling abusing traffic which is free of cost.
According to google "reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep automated software from engaging in abusive activities on your site". The best part is adding reCAPTCHA bots cannot pass this validation, but the valid users can! Isn't it great?
COI is a procedure where you send out an email for confirmation whether the email belongs to you or not. The email consists of a link which states that you have signup successfully and want to activate the account. Similarly, if you are opting for any newsletter, an email will be sent, and you need to click the link which states that you have Opt-In and want to receive newsletters.
This method will not only help you avoid spambot abuse but also help you gain good quality leads or customers, and it reduces the hard bounce because this COI will make the user correct the misspelt or invalid emails.
These fields are extra fields within your form, which are not visible to the human. Bots usually fill all the fields in the form that means if the honeypot fields are filled, they should be immediately marked as invalid or spam.
Spambots are unique and programmed in such a way that they behave like real users. So, these spambots are not that simple to get detected. But, there are few things you should notice which might help you detect which messages are from Spambot and which are from real users.
This section is a combination of both the prevention methods that I have discussed above, and besides those methods, I will be sharing a few more techniques which will give more option to stop spambots.
Spambots are everywhere online. All you can do is prevent and add as much filter as you can on your domain. So that these spambots are not affecting your website anymore.
