CISA and partner cybersecurity agencies and intelligence services warned that the APT29 hacking group linked to Russia's Foreign Intelligence Service has been targeting unpatched TeamCity servers in widespread attacks since September 2023. Security researchers at nonprofit internet security outfit Shadowserver Foundation are tracking almost 800 unpatched TeamCity servers that are vulnerable to attacks.
Roughly 1,450 pfSense instances exposed online are vulnerable to command injection and cross-site scripting flaws that, if chained, could enable attackers to perform remote code execution on the appliance. In mid-November, SonarSource's researchers discovered three flaws impacting pfSense 2.7.0 and older and pfSense Plus 23.05.01 and older.
Security researchers discovered a remote access trojan they named Krasue that is targeting Linux systems of telecommunications companies and managed to remain undetected since 2021. According to researchers at cybersecurity company Group-IB, the main function of the malware is to maintain access to the host, which may suggest that it is deployed through a botnet or sold by initial access brokers to threat actors seeking access to a particular target.
Unknown attackers have leveraged a critical vulnerability in the Adobe ColdFusion application development platform to access government servers, the Cybersecurity and Infrastructure Security Agency has shared. Adobe disclosed and fixed the flaw in mid-March 2023, and said that it was "Aware that CVE-2023-26360 has been exploited in the wild in very limited attacks".
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned of active exploitation of a high-severity Adobe ColdFusion vulnerability by unidentified threat actors to gain initial...
CISA has released details about a federal agency that recently had at least two public-facing servers compromised by attackers exploiting a critical Adobe ColdFusion vulnerability. In a Tuesday advisory, CISA revealed the federal civilian executive branch in question was successfully attacked in June and into July, meaning the vulnerability went unpatched for more than three months after CISA's deadline.
Tens of thousands of Microsoft Exchange email servers in Europe, the U.S., and Asia exposed on the public internet are vulnerable to remote code execution flaws. Internet scans from The ShadowServer Foundation show that there are close to 20,000 Microsoft Exchange servers currently reachable over the public internet that have reached the end-of-life stage.
PolarDNS is a specialized authoritative DNS server that allows the operator to produce custom DNS responses suitable for DNS protocol testing purposes. DNS header malformations Injection of unsolicited records Injection of arbitrary bytes of arbitrary lengths.
A team of academic researchers from universities in California and Massachusetts demonstrated that it's possible under certain conditions for passive network attackers to retrieve secret RSA keys from naturally occurring errors leading to failed SSH connection attempts. A paper published by university researchers Keegan Ryan, Kaiwen He, Nadia Heninger, and George Arnold Sullivan, shows that it's possible for a passive network attacker to obtain a private RSA key from SSH servers experiencing faults during signature computation.
MySQL servers are being targeted by the 'Ddostf' malware botnet to enslave them for a DDoS-as-a-Service platform whose firepower is rented to other cybercriminals. Exploitation of UDF. The attackers are scanning the internet for exposed MySQL servers and, when found, attempt to breach them by brute-forcing administrator credentials.
