At least 20 crypto executives and customers of an Israeli telecommunications company were targeted in a sophisticated SS7 attack last month.
Hackers compromised the Telegram messenger and email accounts of multiple cryptocurrency executives last month by exploiting a vulnerability in a decades old protocol.
The fraudsters are believed to have been trying to intercept two-factor authentication codes of victims in an attack on Israel-based telecommunications provider Partner Communications Company, formerly known as Orange Israel.
The attacks are currently being investigated by Israel’s National Cyber Security Authority, and national intelligence agency Mossad.
According to cybersecurity publication Bleeping Computer, the devices of at least 20 Partner clients were compromised.
