New Glibc Flaw Grants Attackers Root Access on Major Linux Distros

New Glibc Flaw Grants Attackers Root Access on Major Linux Distros

Jan 31, 2024 Vulnerability / Endpoint Security
Malicious local attackers can obtain full root access on Linux machines by taking advantage of a newly disclosed security flaw in the GNU C library (aka glibc). Tracked as CVE-2023-6246 (CVSS score: 7.8), the heap-based buffer overflow vulnerability is rooted in glibc's __vsyslog_internal() function, which is used by  syslog() and vsyslog()  for system logging purposes. It's said to have been accidentally introduced in August 2022 with the release of glibc 2.37. "This flaw allows local privilege escalation, enabling an unprivileged user to gain full root access," Saeed Abbasi, product manager of the Threat Research Unit at Qualys,  said , adding it impacts major Linux distributions like Debian, Ubuntu, and Fedora. A threat actor could exploit the flaw to obtain elevated permissions via specially crafted inputs to applications that employ these logging functions. "Although the  vulnerability  requires specific conditions to be exploited (such as an unusuall

New OpenSSH Vulnerability Exposes Linux Systems to Remote Command Injection

Jul 24, 2023 Linux / Network Security
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. The vulnerability is being tracked under the CVE identifier  CVE-2023-38408  (CVSS score: N/A). It impacts all versions of OpenSSH before  9.3p2 . OpenSSH is a popular connectivity tool for remote login with the SSH protocol that's used for encrypting all traffic to eliminate eavesdropping, connection hijacking, and other attacks. Successful exploitation requires the presence of certain libraries on the victim system and that the SSH authentication agent is  forwarded  to an attacker-controlled system. SSH agent is a  background program  that maintains users' keys

Cybersecurity Tactics FinServ Institutions Can Bank On in 2024

Feb 14, 2024Financial Security / Cyber Threats
The landscape of cybersecurity in financial services is undergoing a rapid transformation. Cybercriminals are exploiting advanced technologies and methodologies, making traditional security measures obsolete. The challenges are compounded for community banks that must safeguard sensitive financial data against the same level of sophisticated threats as larger institutions, but often with more limited resources. The FinServ Threat Landscape Recent trends show an alarming increase in sophisticated cyber-attacks. Cybercriminals now deploy advanced techniques like deep fake technology and AI-powered attacks, making it increasingly difficult for banks to differentiate between legitimate and malicious activities. These developments necessitate a shift towards more sophisticated and adaptive cybersecurity measures. Take these industry statistics, for example. Financial firms report 703 cyberattack attempts per week.1 On average, 270 attacks (entailing unauthorized access of data, appl

Hackers Using Stolen Bank Information to Trick Victims into Downloading BitRAT Malware

Jan 03, 2023 United States
A new malware campaign has been observed using sensitive information stolen from a bank as a lure in phishing emails to drop a remote access trojan called  BitRAT . The unknown adversary is believed to have hijacked the IT infrastructure of a Colombian cooperative bank, using the information to craft convincing decoy messages to lure victims into opening suspicious Excel attachments. The discovery comes from cybersecurity firm Qualys, which  found  evidence of a database dump comprising 418,777 records that's said to have been obtained by exploiting SQL injection faults. The leaked details include C├ędula numbers (a national identity document issued to Colombian citizens), email addresses, phone numbers, customer names, payment records, salary details, and addresses, among others. There are no signs that the information has been previously shared on any forums in the darknet or clear web, suggesting that the threat actors themselves got access to customer data to mount the phi
