The email accounts and Telegram app of many crypto execs were hacked by exploiting old protocol vulnerability.
About twenty-two cryptocurrency executives and clients of a telecom company in Isreal were targets of a hack attack last month. The attack was perpetrated by exploiting signaling system 7 (SS7) programs to transfer data for phone systems.

Major Updates:
- The hackers have been attempting to hijack two-factor authentication codes of clients who had their accounts attacked Israeli Partner Communication company.
- The assaults are presently being looked into by the Israeli Cyber-Security agency and NIA, Mossad.
- Following a Bleeping Computer report, the devices of about twenty customers of the Israeli-based telecommunication provider firm were hacked.
- Pandora, a cyber-security company, based in Israel, alludes that the systems were probably compromised through an SS7 attack after analyzing the situation.
- The signaling system seven consists of programs that aid data transfer within open phone systems that interact over a digitized signaled network.
Fraudsters can capitalize on the signaling system 7 to block messages and phone calls by compromising the roaming feature and changing their system's position, making it seem listed to another system.Regardless that the system designed in 1975, the signaling system seven programs are presently being extensively used worldwide.
