Account takeover and application protection

Code tampering, account abuse, data exposure and client manipulation.

Threats and abuse1 min readEditorial methods

Account risk does not arise only from modified devices. Phishing, weak recovery and server authorization defects require controls different from in-app protection.

Evaluation approach

Sign-in, account recovery, new devices and sensitive profile changes are separate risk flows. RASP can add context to each.

Application example

If a new-device sign-in is immediately followed by a new recipient and a limit increase, assess the sequence's combined risk.

Limits and considerations

Root checks alone do not address stolen passwords or social engineering.

A genuine application in the wrong hands

An attacker may use the genuine application on their own device. A positive integrity verdict does not prove that the account's legitimate owner is operating it. Authentication and recovery need their own threat model.

Assess new devices, contact-detail changes and high-impact operations together. Users should be able to recover access safely and terminate old sessions. Device signals inform account risk; they do not independently determine identity.

Checks and decisions

  • Review recovery flows
  • Monitor operation sequences
  • Apply additional verification

Bring account and application security into one program while managing their different evidence separately.
