MFA Bombing - What is it?

Multi-factor authentication (MFA) and MFA bombing and how cyber criminals are using it to break into accounts.
MFA is a security process that requires more than one method of authentication from independent categories to verify the user's identity for a login or other transaction.  The aim of MFA is to provide an additional layer of security beyond just a username and password.

MFA bombing which is also known as "push bombing" or "MFA fatigue", is a brute force attack on your patience. MFA provides an increase in security and makes life much harder for criminals because of the extra requirements by a user to respond to logging in.  Usually criminals use stolen credentials to try logging in or using them to reset a user's password. Cyber criminals will bombard a use with push notifications by asking them to continually approve the login or messages to change their password.  This works by users  tapping in the wrong option or getting fed up with the notifications.  These attacks have evolved to become more sophisticated with the criminals now calling you pretending to come to your rescue, for example, pretending to call from Apple Support.

What to do in the event of a cyber attack

First, follow your cyber response plan. Record the incident in your internal incident log, inform your governing board or trustees, and contact your Data Protection Officer (DPO) as soon as possible if personal data could be involved.

Incidents or attacks where a security breach may have taken place, or other damage was caused, should also be reported to an external body. The SLT digital lead is responsible for assigning someone to report any suspicious cyber incidents or attacks. This person will need to report to:

  • Report Fraud, which replaced Action Fraud in December 2025, on 0300 123 2040 or through the Report Fraud website. Make sure it is recorded as a crime report so that you receive a crime reference number.
  • the DfE sector cyber team at This email address is being protected from spambots. You need JavaScript enabled to view it.

You may also need to report to:

  • the National Cyber Security Centre (NCSC) if the incident or attack causes long-term school closure, the closure of more than one school, or serious financial damage. If you're not sure who to report to, use the government's cyber incident signposting service.
  • the Information Commissioner's Office (ICO) within 72 hours of becoming aware of a personal data breach, unless the breach is unlikely to result in a risk to people's rights and freedoms. If the risk is high, you must also tell the people affected without undue delay. Your DPO can help you assess this.  We will do this on behalf of DPE customers.
  • the Risk Protection Arrangement (RPA) emergency assistance helpline on 0800 368 6378 or This email address is being protected from spambots. You need JavaScript enabled to view it., if you are an RPA member, or your cyber insurance provider if you have one
  • your local police force if you suspect a safeguarding impact
  • any third-party service providers whose systems are affected, so they can be part of a coordinated response
  • Jisc CSIRT, if you are part of a further education institution.

You must act in accordance with:

Preserve the evidence

Police investigations may find out whether any compromised data has been published or sold, and identify the perpetrator. Preserving evidence is as important as recovering from the crime. Keep a clear record of what happened, when, and what actions you took. The DfE's guidance on record keeping in an incident explains what to capture.

Reporting suspicious emails and texts

Forward suspicious emails to This email address is being protected from spambots. You need JavaScript enabled to view it.. Report scam text messages by forwarding the original message to 7726 (it spells SPAM on the keypad).
