Signal says it will never ask for your registration code, PIN, or recovery key. South African users who rely on Signal for work, activism, journalism, or private chats should treat any “Signal Support” message as suspicious. A new vulnerability discovered by hackers on the Signal app isn’t its encryption feature; it’s its users. Now there’s an outbreak of a new kind of phishing attack aimed at persuading Signal users to give away their backup recovery keys used to decrypt archived chats. These emails claim to be from Signal Support, although according to the company itself, it never initiates contact with its users nor asks for recovery keys. Hackers are now going after Signal backups Signal has built its reputation on privacy. That’s why journalists, activists, executives, political workers, and ordinary users trust it for conversations they don’t want floating around the internet. But privacy tools still have one messy problem: humans click things. According to TechCrunch, hackers are targeting Signal users in a new phishing campaign aimed at stealing chat backups. The attack does not appear to break Signal’s encryption. Instead, attackers impersonate Signal Support and try to pressure users into sharing their backup recovery key. That matters because Signal’s Secure Backups use a 64-character recovery key. Signal says that key never gets shared with its servers, and without it, no one — including Signal — can read or restore the backup archive. So the scam is simple. Don’t hack the lock. Trick someone into handing over the key. How the Signal phishing scam works The phishing message reportedly warns users that their backed-up chats and media could be lost because of a syncing issue. It then tells them to copy their recovery key and send it to a fake “Signal Support” account. That’s the red flag. Signal says it will never reach out first and will never ask for your registration code, PIN, or recovery key. Any message doing that should be treated as a phishing attempt. Here’s the basic pattern: Step What the attacker does What they want 1 Pretends to be Signal Support Your trust 2 Claims your backup is at risk Panic 3 Asks for your recovery key Access to your encrypted archive 4 Tries to take over the account A path into your messages The recovery key alone may not complete the whole attack. But it can become the first step in a larger account takeover attempt. That’s why users should treat it like a banking password or crypto wallet seed phrase. You don’t share it. Ever. Why recovery keys are such a valuable target Signal’s backup design is built around privacy. Your backup archive is end-to-end encrypted, and the recovery key stays with you. Signal cannot recover, reset, or bypass it if you lose it. That protects users from platform-level access. But it also creates a high-value target. If attackers convince you to hand over the recovery key, they may gain access to backed-up messages if they also manage to compromise your account or restore process. For people who use Signal for sensitive work, that could expose names, plans, sources, business conversations, personal media, or years of private context. This is why phishing keeps working. The strongest encryption in the world won’t help if a fake support message convinces you to give away the secret. Why South African users should care This isn’t only a US or European problem. In South Africa, many people use encrypted messaging apps for journalism, community organising, startup work, legal conversations, political discussions, and private family matters. A fake Signal message can land in Cape Town, Johannesburg, Durban, or anywhere else just as easily as it can land in Washington. The risk is bigger for people who already face targeted pressure: activists, reporters, lawyers, executives, political staff, crypto users, and people working with sensitive documents. But normal users should pay attention too. Scammers don’t always know you’re important before they target you. They often send broad campaigns, then focus on whoever responds. For readers following the wider cybersecurity shift, this also fits a bigger pattern: attackers are moving beyond stolen passwords and going after tokens, recovery codes, session access, and backup keys. Memeburn recently covered this wider change in Hackers Aren’t Just Stealing Passwords in 2026. What Signal users should do now The safest move is to treat any unexpected Signal support message as fake unless you verify it through an official channel. Do this instead: Never share your Signal recovery key, PIN, or registration code. Block and report any account pretending to be Signal Support. Don’t click links in urgent account-warning messages. Store your recovery key in a trusted password manager or another safe offline place. Review linked devices inside Signal settings. Use a strong Signal PIN and keep registration lock enabled where available. Warn your contacts if you think your account was compromised. Signal’s own phishing guidance says users should verify identities through another channel and avoid sharing codes or passwords with anyone pretending to be a friend, company, or support team. That’s boring advice. It’s also the advice that works. The bigger lesson: privacy tools still need user caution Signal’s Secure Backups solve a real problem. People lose phones. Devices break. Chats matter. Secure backups give users a way to restore message history without handing Signal the power to read it. But every recovery system creates a new responsibility. If the recovery key unlocks your archive, attackers will try to steal that key. If users trust fake support accounts, hackers will keep pretending to be support. If panic works, scammers will keep writing urgent messages. The good news is that this attack has a clear defence: don’t share the key. Signal hasn’t become useless because scammers are targeting it. But the campaign shows how privacy now depends on both strong technology and calm user behaviour. So the next time a “support” account tells you your private messages are about to disappear, will you pause before you copy the key? FAQs Is Signal hacked? No, this campaign targets users through phishing, not Signal’s core encryption. The hackers disguise themselves as Signal Support team members in order to frighten their victims into sharing recovery data for Signal with them. What is a Signal recovery key? A Signal recovery key is a 64-character code used to unlock encrypted backups. It works like a master key for your saved chat archive, so you should treat it like a banking password or crypto wallet seed phrase. Signal says it can’t recover or reset this key for you if you lose it. What should I do if “Signal Support” messages me? Consider the matter as a potential scam, especially if the message mentions requesting your PIN, registration code, or recovery key from you. Signal representatives have stated that they never get in touch with their users first before asking for sensitive data related to accounts. Don’t reply, don’t click any links, and report or block the account inside the app. Can hackers access my Signal message history using my recovery key? Hackers will not get everything out of the key, but the key poses a huge risk to the user since attackers might use it as a means of restoring your Signal backed up data. The key must be kept safe at all times. Signal users must never give it to anyone, including the support team.
