Cisco warns about a large-scale credential brute-forcing campaign targeting VPN and SSH services on Cisco, CheckPoint, Fortinet, SonicWall, and Ubiquiti devices worldwide. The researchers say the attacks started on March 18, 2024, while all attacks originate from TOR exit nodes and various other anonymization tools and proxies, which the threat actors use to evade blocks.

Hackers have managed to compromise a telephony provider for Duo, the Cisco-owned company providing secure access solutions, and steal MFA SMS message logs of Duo customers."The threat actor downloaded message logs for SMS messages that were sent to certain users under your Duo account between March 1, 2024 and March 31, 2024," the Cisco Data Privacy and Incident Response Team notified its MSP partners.

Cisco Duo's security team warns that hackers stole some customers' VoIP and SMS logs for multi-factor authentication messages in a cyberattack on their telephony provider. In emails sent to customers, Cisco Duo says an unnamed provider who handles the company's SMS and VOIP multi-factor authentication messages was compromised on April 1, 2024.

Roderich Kiesewetter, deputy chairman of the German parliament's oversight committee, said the Bundeswehr leak was possibly caused by a Russian agent inside the WebEx call or the Bundeswehr's implementation of it, but the country is still working on discovering how the intrusion took place. RT has since made a number of claims after publishing the call, including that the conversation provides proof that Germany was planning to help Ukraine to destroy the Kerch Bridge that connects Russia to the illegally annexed Crimea.
