Reducing Risk Of Email Bombing Attacks
It is easy to understand why registration bombing is a successful tactic and a reasonable evolution of the email bomb. Its easy to deploy and time-consuming to resolve. Moving forward, everyone should be extra cognizant of unsolicited emails, especially those in mass quantity that are requesting an action be taken.
BlackCloak members who think they might have been impacted by the Walmart.com registration bombing attack, or suspect an email bombing attack in the future should contact the Concierge Support Team immediately for investigation, analysis and the appropriate response. And of course, dont forget to deploy multi-factor authentication on Walmart.com and on any other e-commerce accounts that offer it.
What Can An Msp Do
An email bomb against one or two employees has the potential to bring down an entire network if the volume is high enough. The daily hum of office activity could be brought to a halt. In the case of the Pro Politica reports, the only recourse was to block all incoming email . However, as with many types of malware and cyber security threats, an MSPs best defense is prevention and that often merely consists of education. The best way to avoid this is to have a separate email account that you use for signing up for services. Menczer and colleagues have explored ways to prevent email bombing and outline some more in-depth and technical solutions here.
We describe a solution to be deployed by services that offer online newsletter subscription so that they cannot be abused in this way. They should use a kind of two-step authentication to ensure that the person subscribing is the one who will receive the emails, Menczer says. And while this type of attack is more difficult for potential target individuals to defend against, the server-based email services of today are more resilient than when email bombing first was noticed over a decade ago.
You Cant Stop The Attack But You Can Wait It Out
Ultimately, theres nothing you can do to stop the attack yourself. If your email provider cant or wont help, youll have to endure the attack and hope it stops.
Just be aware you may be in for a long haul. While email bombings sometimes trail off after a day, they can go on as long the perpetrator wants or has the resources for. It may be a good idea to contact anyone important, make them aware of whats going on, and provide another way to contact you. Eventually, either your attacker will get what they want or realize youve taken the steps to prevent them from succeeding and move on to an easier target.

Email Bombs Disguise Fraud
Email Bombs Continue to Disguise Fraud
Email bombs are a type of Denial of Service attack. Victims face an uncontrollable deluge of messages quickly filling up their inbox when the attack begins. With enough volume, the attack renders the victims mailbox useless. Victims struggle to make sense why a sudden avalanche of messages are filling up their inbox, however, this is no accident.
Motives for the attack vary but the vast majority we see are to perpetrate some type of fraudulent activity with the victims compromised information. The bomb is typically designed to distract the user from emails generated due to fraudulent purchases or financial account updates or transactions. During these type of attacks, we’ve observed fraudulent airline ticket purchases, Apple store orders, and quite a few Best Buy pickup orders. If applicable to the fraudulent purchase – such as a Best Buy pickup order, attackers have mules ready to quickly pick up the fraudulently purchased merchandise soon after the attack begins.
HOW email bomb ATTACKS WORK
Weak Website Newsletter & Form Sign-Up Verification
While email bombing attack methods vary, most attacks we observe use legitimate newsletter sign-ups from normal websites. The email bombers utilize automated bots which crawl the web searching for newsletter sign-up pages or forms that dont require a form of live-user authentication.

What Is A Mail Bomb
A mail bomb is a form of a denial-of-service attack designed to overwhelm an inbox or inhibit a server by sending a massive number of emails to a specific person or system. The aim is to fill up the recipient’s disk space on the server or overload a server to stop it from functioning.
Also known as email bombs and letter bombs, mail bombs inconvenience not only the intended target but everyone who uses the server. When a server is unresponsive, it can degrade network performance and potentially lead to downtime.
Mail bomb attacks are usually initiated — intentionally or unintentionally — by a botnet, a single actor or a group of actors. The damage caused by a mail bomb can range from a minor inconvenience to a total disruption of services. Mail bomb attacks can last for several hours if no effort is made to filter, mitigate or block the attacking traffic.
New Registration Bomb Email Attack Distracts Victims Of Financial Fraud
Email bombing attacks, in which bots flood an email address or server with hundreds to thousands of email messages, have been a significant thorn in the sides of CISOs and ordinary email users since the late 2000s. This nefarious act, which can achieve a similar outcome to that of a distributed denial of service attack, is also frequently deployed to distract and hide important emails.
One of the most notable email bombing campaigns came in 2016 when, according to Brian Krebs, unknown assailants launched a massive cyber attack aimed at flooding targeted dot-gov email inboxes with subscription requests to thousands of email lists. The email server was so overwhelmed that many .gov email addresses remained unusable for days.

What Is Email Bombing Or Subscription Bombing
If you suddenly start to receive an unusual amount of junk email, by the hundreds or thousands, or a massive amount of subscription email confirmations, you are probably the victim of Email Bombing a.k.a. Subscription Bombing. The perpetrator is using this technique in an effort to try to hide their real goal.
What To Do When You Get Email Bombed
If you find yourself the victim of email bombing, the first thing to do is check and lock down your accounts. Log into any shopping accounts, like Amazon, and check for recent orders. If you see an order that you didnt place, contact the shopping websites customer support immediately.
You may want to take this a step further. On Amazon, its possible to archive orders and hide them from the normal order list. One Reddit user discovered an email from Amazon confirming an order for five graphics cards with a total value of $1000 buried in an onslaught of incoming email. When they went to cancel the order, they couldnt find it. The attacker had , hoping thatd help it go undetected.
You can check for archived Amazon orders by going to Amazons Your Account page and clicking on Archived Orders under Ordering and shopping preferences.
While youre checking your shopping accounts, it would be wise to remove your payment options entirely. If the perpetrator is still waiting to break into your account and order something, they wont be able to.
Its doubtful anyone from this support team can help with your problem. If youre on Gmail without a subscription, youre going to have to ride out the bombing. You can create filters to clean out your inbox. Try to find something common in the emails you are receiving and set a few filters to move them to spam or trash. Just to be careful not to filter out emails you do want to see in the process.

What Is Email Bombing
An email bombing is an attack on your inbox that involves sending massive amounts of messages to your address. Sometimes these messages are complete gibberish, but more often theyll be confirmation emails for newsletters and subscriptions. In the latter case, the attacker uses a script to search the internet for forums and newsletters and then signs up for an account with your email address. Each will send you a confirmation email asking to confirm your address. This process repeats across as many unprotected sites as the script can find.
The term email bombing can also refer to flooding an email server with too many emails in an attempt to overwhelm the email server and bring it down, but thats not the goal hereit would be challenging to bring down modern email accounts that use Google or Microsofts email servers, anyway. Instead of a denial-of-service attack against the email servers you are using, the onslaught of messages is a distraction to hide the attackers true intentions.
