As an IT student here in Poltava, I spend plenty of time studying network security and learning about complicated vulnerabilities. We are usually taught to look for sophisticated malware or advanced persistent threats. But I recently read a fascinating series of posts on a blog called The Hacker’s Mirror that explores a completely different kind of cyberattack. The author breaks down three variations of digital flooding known as subscription bombing, SMS bombing, and phone call bombing.
What caught my attention right away is that these attacks do not require the hacker to break into your accounts or bypass heavy encryption. Instead, they weaponize the very notification systems we rely on every day.
The core idea across all three articles is that attackers use automated scripts to overwhelm a target with legitimate messages. For email bombing, an attacker takes your email address and feeds it into thousands of unprotected newsletter signup forms. For SMS and phone call flooding, they abuse websites that have automated verification systems or call back requests. Your phone starts ringing constantly from spoofed numbers, or your inbox fills up with tens of thousands of welcome messages in a matter of hours.
While some people might brush this off as a harsh prank, the articles highlight a much darker motive. Attackers use these massive floods of digital noise as a smokescreen. If a hacker manages to compromise your bank account and initiates a large money transfer, they know your bank will send you a security alert. To make sure you never see that crucial message, they trigger a bombing attack. The legitimate fraud warning gets completely buried under thousands of random subscriptions or text messages. By the time the flood stops and you realize what happened, your money is already gone.
From a developer perspective, this is a massive wake up call. When I write code for web forms, my main goal is usually a smooth user experience. But these attacks only work because developers leave application programming interfaces and signup forms wide open. The Hacker’s Mirror points out that attackers rely on websites that lack basic bot protection. If a website allows someone to submit a phone number or email address hundreds of times a minute without rate limiting, that site essentially becomes an accomplice in the attack.
The author strongly suggests that developers need to implement strict double opt in protocols. If every single newsletter or web service required users to click a confirmation link before sending any further messages, email bombing would be almost entirely neutralized. The same goes for adding invisible honeypots or basic rate limits to stop automated scripts in their tracks.
The articles also offer some incredibly practical advice for anyone who falls victim to one of these attacks. The natural human reaction is to panic. You might be tempted to start manually clicking unsubscribe on every single email or picking up the phone to yell at the automated dialers. The author warns that doing this is a huge mistake. Clicking links in a flooded inbox can lead you straight to a hidden phishing site, and answering spoofed calls only confirms to the attacker that your number is active.
Instead, the immediate priority should be securing your financial accounts. You should use a separate device to log into your bank and check for unauthorized transactions. For your inbox, the best defense is setting up a temporary filter to quarantine words like subscription, confirm, or welcome. This pulls the junk out of your main view so you can actually search for real security alerts. For phone floods, turning on Do Not Disturb and allowing only your saved contacts to ring through will give you the mental space to contact your carrier and ask for a fraud trace.
Reading this series really reinforced a concept we talk about a lot in my IT classes. Security is not just about building strong walls around a database. It is also about anticipating how perfectly normal features can be abused at scale. We have to design systems that protect users from malicious automation just as much as we protect them from direct breaches.
