A new Android malware named 'Hook' is being sold by cybercriminals, boasting it can remotely take over mobile devices in real-time using VNC. The new malware is promoted by the creator of Ermac, an Android banking trojan selling for $5,000/month that helps threat actors steal credentials from over 467 banking and crypto apps via overlaid login pages. While the author of Hook claims the new malware was written from scratch, and despite having several additional features compared to Ermac, researchers at ThreatFabric dispute these claims and report seeing extensive code overlaps between the two families.
So Don was rather surprised one day to hear a phone ringing as he stalked the racks, because the kit there was dedicated to modems. "The caller only said 'BOMB. BOMB. BOMB.' with a strong Irish accent," don recalled.
Boffins based in China and the UK have devised a telecom network attack that can expose call metadata during VoLTE/VoNR conversations. Researchers Zishuai Cheng and Baojiang Cui, with the Beijing University of Posts and Telecommunications, and Mihai Ordean, Flavio Garcia, and Dominik Rys, with the University of Birmingham, have found a way to access encrypted call metadata - VoLTE activity logs that describe call times, duration, and direction for mobile network conversations.
" I don't even think turning your cell phone off would help in this instance. Oh and do not think that "Turning the phone off" actually works, it does not, the phone remains powered up but supposadly in some quiescent mode.

"You still have a lot of soldiers bringing cellphones to the frontline who want to talk to their families and they are either being intercepted as they go through a Ukrainian telecommunications provider or intercepted over the air," said Alperovitch. "That doesn't pose too much difficulty for the Ukrainian security services."
Argishti Khudaverdyan, the former owner of a T-Mobile retail store, was sentenced to 10 years in prison for a $25 million scheme where he unlocked and unblocked cellphones by hacking into T-Mobile's internal systems. "Removing the unlock allowed the phones to be sold on the black market and enabled T-Mobile customers to stop using T-Mobile's services and thereby deprive T-Mobile of revenue generated from customers' service contracts and equipment installment plans."
A high-risk stack overflow vulnerability may allow attackers to DoS or possibly even execute code remotely on Cisco 7800 and 8800 Series IP phones, the company has confirmed. Cisco's PSIRT is also aware that proof-of-concept exploit code is available for the vulnerability and that the flaw has been publicly discussed, but they are not aware of active attacks exploiting it.
Cisco has released a new security advisory warning of a high-severity flaw affecting IP Phone 7800 and 8800 Series firmware that could be potentially exploited by a remote attacker to cause remote code execution or a denial-of-service condition. The networking equipment major said it's working on a patch to address the vulnerability, which is tracked as CVE-2022-20968 and stems from a case of insufficient input validation of received Cisco Discovery Protocol packets.
