Silent Calls Push Bitdefender Warning on Arnaque Allo Telephone
Bitdefender says arnaque allo telephone scams now begin with an unknown number and a silent line after the call is answered. RMC reported that the tactic is gaining traction as a way to verify active numbers and collect voices for later abuse.
Answering the call tells scammers the line is assigned. Bitdefender says that number can then be resold on the dark web, while any voice sample may be used for identity theft attempts, bank-detail fraud, or calls meant to deceive relatives.
Bitdefender and Silent Calls
The company says copying a voice, timbre, and intonation is much easier than people think and can take only a few seconds. It also warns that scammers can use spoofing techniques to make an incoming number look trustworthy, including a bank or a known company.
The silence is part of the setup. Bitdefender says it can encourage the recipient to speak, giving the caller a usable recording. That recording can then be exploited on the dark web or cloned with artificial intelligence.
What To Do After Answering
Bitdefender says the safest response is to let unknown calls ring without answering. If someone does pick up a silent call, the source says not to speak or give personal information, then hang up immediately.
The advice continues with blocking the number and reporting it. If the call is legitimate, Bitdefender says the caller may leave a voicemail, send a text message, or call again directly. It also says never to call back unknown numbers because they could redirect to premium-rate services.
Unsolicited Calls In France
The warning sits inside a broader rise in unsolicited and telemarketing calls over recent years. Bitdefender presents the guidance as part of its digital protection advice, but the practical rule is simple: a silent call can still be a probe, not a mistake.
For anyone who answers an unknown number, the next move is fast and limited — hang up, block the line, and do not feed the caller a voice sample or any detail that can be reused later.
