The duties of a Spam Auditor involves more than just spam filtering; it also covers other suspicious mail server activity. One example of suspect mail server activity is SMTP Auth attacks. Such attacks can be carried by a single attacker, or an attacker using an army of compromised servers (botnet) with the same goal. There are many purposes behind an SMTP Auth Attack.

Email Harvesting

One purpose of an SMTP Auth attack is to harvest email addresses. A server can be hammered with connections that attempt various .*@domain to discover real email addresses. When a connection is attempted with an invalid address, an error message may occur which informs the connecting server that the address provided was invalid. Harvested email addresses can be compiled into lists which can then be sold/used for other purposes.

Credential Cracking

Once real addresses are discovered, hackers can then begin to brute force or dictionary attack the address in an attempt to discover the login credentials. This is where users with poor, easy, or common passwords can get compromised, and why it is always a good idea to require ‘hard’ passwords for your customers if you are an email service provider.

Hackers would usually go after the ‘low hanging fruit’ first. They can compile lists of the most commonly used passwords to improve their odds of quickly discovering the passwords to accounts.

Another source of credential information are data breaches. We hear about these far too often today. Reported data breaches can be massive in scale (approximately 300 million or more in the Marriott breach). Depending on the database security of such breaches sometimes even the full user/password combinations are exposed. Unfortunately, it is very common for people to reuse passwords across multiple accounts; this increases the risk of getting your accounts hacked, as it only takes one insecure server that you have an account on to leave the rest of your accounts vulnerable.

Compromised Accounts

Once the password of an email address is discovered, the account is effectively compromised. It will likely be used in various ways such as sending spam. Sometimes that spam is as simple as sending affiliate advertising, but usually the spam a hacker would send is MUCH more dangerous, such as Virus and Phishing Attacks. But even worse, the hacker now has access to all YOUR valuable information, including contacts, emails, and other personal information.

Nowadays, email addresses are linked to valuable accounts (digital wallets, important accounts, etc). This makes some ‘important’ addresses very sought after by criminals, and can lead to the theft of valuables and even identity.

Social engineering is another threat that stems from compromised accounts. For example, if it is a business email address, the email inbox can be analyzed for private information within that company. This information can be used in spear phishing attacks, allowing for malicious acts such as false wire transfers, malware (e.g. ransomware) infection, and proprietary data theft.

Solutions to SMTP Auth Attacks?

Today, the problem of SMTP Auth attacks is simply too big for traditional techniques to work. For example, if one were to attempt to block the IPs found participating in such attacks, the sheer amount of unique IPs will be overwhelming. Many of these are dynamic, end-user type connections, with compromised devices in the Internet of Things (IoTs). This makes blocking by IP not a very effective strategy, especially as that might affect hundreds of innocent people sharing that same IP, or when the IP address changes hands.

Without new methods for defending against SMTP Auth attacks, it is clear that everyone is at risk. Luckily, such technology does exist in order to fight this battle. Products such as MagicMail, MagicSpam, and others, allow protection against SMTP attacks with simple to use AUTHentication controls, which provide ways to control “WHO” can attempt to use your email and password, and from where and when. Various proprietary and freely available techniques related to ‘two-factor’ authentication, can make a difference without blocking legitimate connections.

Finally, Where are these Attacks Coming From?

Our spam auditing technologies can detect much of the methods and techniques used by hackers, and the ‘botnet’ sources participating in such activity, and the results are astonishing. Below is a list of some of the top offenders detected in a recent 24 hour period at just a single email server. Much of the attacks are coming from foreign ISP’s, in Vietnam, China, Brazil, and India. This can represent millions of attack sources. Ask your ISP on how to block authentication from countries you don’t visit.
