iTWire - Singtel's 'old data' first posted on dark web in Feb 2021: researcher
Data stolen during an attack on Singapore's multinational telecommunications conglomerate Singtel, which the company says was exfiltrated on 20 January last year, has been lying on the dark Web since February 2021 and was reposted to a clear Web forum on 7 October, a security professional says.
Brett Callow, a senior security researcher with the New Zealand-based Emsisoft, told iTWire that the data had been originally posted on the dark web site of the Windows ransomware group, Cl0p.
"In February 2021, Cl0p posted data that it claimed was stolen from Singtel, and it’s that data which Singtel states is now being shared via the forum in question," he said. [A screenshot he took at the time is below.]
Callow's statement appears to refute a claim made the Guardian Australia which read: "Singtel informed those affected, but the post on the data leak forum is believed to be the first time the data has purportedly been posted online."
