Cisco Systems has released  security updates  to address vulnerabilities in multiple Cisco products that could be exploited by an attacker to log in as a root user and take control of vulnerable systems. Tracked as  CVE-2021-40119 , the vulnerability has been rated 9.8 in severity out of a maximum of 10 on the CVSS scoring system and stems from a weakness in the SSH authentication mechanism of Cisco Policy Suite. "An attacker could exploit this vulnerability by connecting to an affected device through SSH," the networking major explained in an advisory, adding "A successful exploit could allow the attacker to log in to an affected system as the root user." Cisco said the bug was discovered during internal security testing. Cisco Policy Suite Releases 21.2.0 and later will also automatically create new SSH keys during installation, while requiring a manual process to change the default SSH keys for devices being upgraded from 21.1.0. Also addressed by Cisco a

Cybersecurity researchers have disclosed a security flaw in the Linux Kernel's Transparent Inter Process Communication ( TIPC ) module that could potentially be leveraged both locally as well as remotely to execute arbitrary code within the kernel and take control of vulnerable machines. Tracked as CVE-2021-43267 (CVSS score: 9.8), the heap overflow vulnerability "can be exploited locally or remotely within a network to gain kernel privileges, and would allow an attacker to compromise the entire system," cybersecurity firm SentinelOne  said  in a report published today and shared with The Hacker News. TIPC is a transport layer  protocol   designed  for nodes running in dynamic cluster environments to reliably communicate with each other in a manner that's more efficient and fault-tolerant than other protocols such as TCP. The vulnerability identified by SentinelOne has to do with insufficient validation of user-supplied sizes for a new message type called "

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

This article was written by Peter Gerdenitsch, Group CISO at Raiffeisen Bank International, and is based on a presentation given during Imvision's Executive Education Program, a series of events focused on how enterprises are taking charge of the API security lifecycle. Launching the "Security in Agile" program Headquartered in Vienna, Raiffeisen Bank International (RBI) operates across 14 countries in Central and Eastern Europe with around 45,000 employees. Our focus is on providing universal banking solutions to customers, as well as developing digital banking products for the retail and corporate markets. Accordingly, RBI has a substantial R&D division, making for a very large community of IT and engineering professionals all over Europe. Back in 2019, we began shifting to a product-led agile setup for RBI, introducing various security roles contributing and collaborating to achieve our strategic goals. As part of this journey, we established the security champ

The U.S. Commerce Department on Wednesday added four companies, including Israel-based spyware companies NSO Group and Candiru , to a list of entities engaging in "malicious cyber activities." The agency said the two companies were added to the list based on evidence that "these entities developed and supplied spyware to foreign governments that used these tools to maliciously target government officials, journalists, businesspeople, activists, academics, and embassy workers." "These tools have also enabled foreign governments to conduct transnational repression, which is the practice of authoritarian governments targeting dissidents, journalists, and activists outside of their sovereign borders to silence dissent," the Commerce Department  said . Two other firms on the list include Singapore-based Computer Security Initiative Consultancy PTE. LTD . and Russia's Positive Technologies , the latter of which was already  sanctioned  by the U.S. Depa

An analysis of new samples of BlackMatter ransomware for Windows and Linux has revealed the extent to which the operators have continually added new features and encryption capabilities in successive iterations over a three-month period. No fewer than 10 Windows and two Linux versions of the ransomware have been observed in the wild to date, Group-IB threat researcher Andrei Zhdanov said in a report shared with The Hacker News, pointing out the changes in the implementation of the  ChaCha20 encryption  algorithm used to encrypt the contents of the files. BlackMatter  emerged  in July 2021 boasting of  incorporating  the "best features of DarkSide, REvil, and LockBit" and is considered the successor to DarkSide, which has since shut down alongside REvil in the wake of law enforcement scrutiny. Operating as a ransomware-as-a-service (RaaS) model, the BlackMatter is believed to have hit more than 50 companies in the U.S., Austria, Italy, France, Brazil, among others. What&

For most organizations today, the logs produced by their security tools and environments provide a mixed bag. On the one hand, they can be a trove of valuable data on security breaches, vulnerabilities, attack patterns, and general security insights. On the other, organizations don't have the right means to manage the massive scale of logs and data produced to derive any value from it.  Log management can quickly become a sore point, and either be forgotten or improperly managed if done manually. In turn, this reduces data transparency and leaves organizations more exposed to vulnerabilities that could have been detected. A new centralized log management module (CLM) introduced by XDR provider Cynet ( learn more here ) could help organizations lighten that load and enhance organizations' visibility into their valuable log data.  Instead of manually handling the collection, storage, and parsing of data, organizations can use CLM to enhance their log analysis, better understand thei

The operators behind the Mekotio banking trojan have resurfaced with a shift in its infection flow so as to stay under the radar and evade security software, while staging nearly 100 attacks over the last three months. "One of the main characteristics […] is the modular attack which gives the attackers the ability to change only a small part of the whole in order to avoid detection," researchers from Check Point Research said in a report shared with The Hacker News. The latest wave of attacks are said to primarily target victims located in Brazil, Chile, Mexico, Peru, and Spain. The development comes after Spanish law enforcement agencies in July 2021  arrested  16 individuals belonging to a criminal network in connection with operating Mekotio and another banking malware called Grandoreiro as part of a social engineering campaign targeting financial institutions in Europe. The evolved version of the Mekotio malware strain is designed for compromising Windows systems wit
