Security & Scams

Phishing, scams, intrusions and data breaches, and the steps people can take to protect themselves.

Implanted chips in Ledger hardware wallets

On 15 October Ledger confirmed that a criminal group had fitted genuine hardware wallets with parts that capture the recovery phrase during setup, then put them on the market through resellers in Southeast Asia. As of 13 October, the thefts Ledger had confirmed were all tied to devices sold by authorised reseller CryptoBilis, and reports of implants from other channels were unconfirmed. Ledger's Genuine Check cannot detect these implants, and Ledger advises anyone who bought and set up a device from CryptoBilis to move their assets to a new device and a new recovery phrase.

The passkey attestation debate

On 10 October a commentary argued against using passkeys because sites can use attestation to restrict which devices and software people may use, and on 14 October an author published a response. Both agree that passkeys are, in most cases, bound to a domain and resist phishing; they disagree on whether attestation will become a restriction, and on whether to keep using passkeys or switch to something else.

Beeline's AI voice personas for scam calls

Russian carrier Beeline said on 6 October that it has routed 19.1 million scam calls to AI voice personas since the start of 2026, according to its own figures.

Website and app breaches in Japan since September 2026

Since mid-September, a string of Japanese companies have disclosed breaches of their websites and apps. Car-sharing service Times Car said data from about 6.6 million accounts was taken, including ID images such as driver's licences for about 1.6 million. As of 9 October we found no official attribution, and the Chief Cabinet Secretary said on 6 October it was unclear whether the incidents were related. Readers outside Japan are affected only if they hold accounts with these services.

Firefox 157's TLS key logging warning

Firefox 157 for desktop, released on 29 September, shows a warning when the computer is set up to record encryption keys. Mozilla's support page says antivirus or security software is the most likely cause and the warning does not mean the computer is infected. If sites fail to load, check that software's HTTPS scanning first.

Vulnerability disclosure and reporting channels in open source projects

As of 8 October, Radicle had no release fixing its network protocol flaws, and people using private repositories should follow its advice. Accounts differ on whether Xray-core told users about a February fix, and Google's open source vulnerability reward programme stopped taking product vulnerability reports on 1 October.

GLM-5.3's exploit-writing ability and open-weight safeguards

Anthropic's report on Zhipu's open-weight model GLM-5.3, published on 29 September, says the model can write working browser exploits and that, in simulated tests, cover stories and similar techniques got past its safeguards. Zhipu's release notes say the public weights carry only the model's own safeguards and that strong defensive capability should not stay with a few organisations. What most readers can do is restart their browser promptly after updates.

Phishing emails that fake Gmail's attachment preview

Cisco Talos found phishing emails sent to Taiwan's academic, think tank and civil society policy community that use images in the message body to imitate Gmail's attachment card, starting an infection on Windows when clicked. Opened in a browser, the fake card is nearly indistinguishable from a real attachment, so people who often receive speaking invitations or institutional mail may want to watch for it.
