In a new joint advisory, cybersecurity and intelligence agencies from the U.S. and other countries are urging users of Ubiquiti EdgeRouter to take protective measures, weeks after a botnet comprising infected routers was felled by law enforcement as part of an operation codenamed Dying Ember.
The botnet, named MooBot, is said to have been used by a Russia-linked threat actor known as
A recently open-sourced network mapping tool called SSH-Snake has been repurposed by threat actors to conduct malicious activities.
"SSH-Snake is a self-modifying worm that leverages SSH credentials discovered on a compromised system to start spreading itself throughout the network," Sysdig researcher Miguel Hernández said.
"The worm automatically searches through known credential
Security researchers from Ruhr University Bochum have discovered a vulnerability in the Secure Shell (SSH) cryptographic network protocol that could allow an attacker to downgrade the connection's security by breaking the integrity of the secure channel.
Called Terrapin (CVE-2023-48795, CVSS score: 5.9), the exploit has been described as the "first ever practically exploitable prefix
Poorly secured Linux SSH servers are being targeted by bad actors to install port scanners and dictionary attack tools with the goal of targeting other vulnerable servers and co-opting them into a network to carry out cryptocurrency mining and distributed denial-of-service (DDoS) attacks.
"Threat actors can also choose to install only scanners and sell the breached IP and account credentials on
A new study has demonstrated that it's possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational faults that occur while the connection is being established.
The Secure Shell (SSH) protocol is a method for securely transmitting commands and logging in to a computer over an unsecured network. Based on a
Proof-of-concept (PoC) exploit code has been made available for a recently disclosed and patched critical flaw impacting VMware Aria Operations for Networks (formerly vRealize Network Insight).
The flaw, tracked as CVE-2023-34039, is rated 9.8 out of a maximum of 10 for severity and has been described as a case of authentication bypass due to a lack of unique cryptographic key generation.
“A
Details have emerged about a now-patched flaw in OpenSSH that could be potentially exploited to run arbitrary commands remotely on compromised hosts under specific conditions.
"This vulnerability allows a remote attacker to potentially execute arbitrary commands on vulnerable OpenSSH's forwarded ssh-agent," Saeed Abbasi, manager of vulnerability research at Qualys, said in an analysis last week.
