Judaism's category is straightforward: hacking is geneivah, theft, and the rabbis were strict about intangible taking. The Talmud holds someone liable as a robber for using another's property without permission even if nothing was permanently removed and even if value was returned (Bava Kamma 97b) — a rule that maps perfectly onto logging into someone's account 'just to look.' The tradition also pioneered privacy as a protected legal interest: harm by seeing (hezek re'iyah, Bava Batra 2b-3a) is actionable damage, so the mere reading of private correspondence is an injury independent of what is done with it. Maimonides codifies that theft of any magnitude transgresses a negative commandment, and Jewish law requires restitution — in modern application, notification, cleanup, and compensation. Where a real crime is suspected, halakha channels evidence to proper authorities, not to self-appointed investigators.

- Never access an account you were not authorized to use — including a partner's or child's, without open agreement.
- If you have hacked someone, the honest path is confession to them, fixing the damage, and accepting the consequences.
- Jewish: Know that even borrowed access without permission is robbery under Bava Kamma 97b; make restitution, not just apology.
- All: Protect your own accounts with strong passwords and two-factor authentication — guarding what is entrusted to you is also a duty.
Repentance: Teshuvah
The Talmud teaches that teshuvah was created before the world itself — Hashem believed in your return before you were born. The gates of return are open now.

Is hacking my own family member's account a sin?
Authorization is the whole question; if they knowingly gave you the password, there is no intrusion.
Authorization is the whole question; if they knowingly gave you the password, there is no intrusion. Jewish law recognizes the privacy injury even between relatives.
What about hacking to expose a criminal?
Traditions direct evidence to lawful authority, not to vigilante action; what you may do: preserve evidence legally and report it.
Traditions direct evidence to lawful authority, not to vigilante action; what you may do: preserve evidence legally and report it. Judaism permits reporting to courts, not public exposure.
Are security professionals sinning when they hack systems?
No — authorization changes the act entirely.
No — authorization changes the act entirely. Pentesters work under contract, with defined scope and consent, which removes theft and trespass. All three traditions distinguish consented activity from intrusion. The sin lies in access without right, not in the technical skill itself.
