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 "...

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, am...

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 unders...

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...

Facebook's  newly-rebranded  parent company Meta on Tuesday announced plans to discontinue its decade-old "Face Recognition" system and delete a massive trove of more than a billion users' facial recognition templates as part of a wider initiative to limit the use of the technology across its products. The Menlo Park tech giant  described  the about-face as "one of the largest shifts in facial recognition usage in the technology's history." The shutdown, which is expected to take place over the coming weeks, will mean users who have previously opted into the setting will no longer be automatically recognized in Memories, photos and videos or see suggested tags with their name in photos and videos they may appear in. Furthermore, the company's Automatic Alt Text (AAT) tool, which creates image descriptions for visually impaired people, will no longer include the names of people identified in photos. Facebook's discontinuing of the program com...

Google has rolled out its monthly security patches for Android with fixes for 39 flaws, including a zero-day vulnerability that it said is being actively exploited in the wild in limited, targeted attacks. Tracked as CVE-2021-1048 , the zero-day bug is described as a  use-after-free vulnerability  in the kernel that can be exploited for local privilege escalation. Use-after-free issues are dangerous as it could enable a threat actor to access or referencing memory after it has been freed, leading to a " write-what-where " condition that results in the execution of arbitrary code to gain control over a victim's system. "There are indications that CVE-2021-1048 may be under limited, targeted exploitation," the company  noted  in its November advisory without revealing technical details of the vulnerability, the nature of the intrusions, and the identities of the attackers that may have abused the flaw. Also remediated in the security patch are two critical re...

A now-patched critical remote code execution (RCE) vulnerability in GitLab's web interface has been detected as actively exploited in the wild, cybersecurity researchers warn, rendering a large number of internet-facing GitLab instances susceptible to attacks. Tracked as  CVE-2021-22205 , the issue relates to an improper validation of user-provided images that results in arbitrary code execution. The vulnerability, which affects all versions starting from 11.9, has since been  addressed  by GitLab on April 14, 2021 in versions 13.8.8, 13.9.6, and 13.10.3. In one of the real-world attacks  detailed  by HN Security last month, two user accounts with admin privileges were registered on a publicly-accessible GitLab server belonging to an unnamed customer by exploiting the aforementioned flaw to upload a malicious payload "image," leading to remote execution of commands that granted the rogue accounts elevated permissions. Attacks exploiting the vulnerability ar...

Google on Monday announced that it will pay security researchers to find exploits using vulnerabilities, previously remediated or otherwise, over the next three months as part of a new bug bounty program to improve the security of the Linux kernel. To that end, the company is expected to issue rewards worth $31,337 (a reference to Leet ) for exploiting privilege escalation in a lab environment for each patched vulnerability, an amount that can climb up to $50,337 for working exploits that take advantage of zero-day flaws in the kernel and other undocumented attack techniques. Specifically, the program aims to uncover attacks that could be launched against Kubernetes-based infrastructure to defeat process isolation barriers (via NSJail) and break out of the sandbox to leak secret information. The program is expected to last until January 31, 2022. "It is important to note, that the easiest exploitation primitives are not available in our lab environment due to the hardening ...

Multiple vulnerabilities have been disclosed in Hitachi Vantara's Pentaho Business Analytics software that could be abused by malicious actors to upload arbitrary data files and even execute arbitrary code on the underlying host system of the application. The security weaknesses were  reported  by researchers Alberto Favero from German cybersecurity firm Hawsec and Altion Malka from Census Labs earlier this year, prompting the company to  issue  necessary patches to address the issues. Pentaho is a Java-based business intelligence platform that offers data integration, analytics, online analytical processing (OLAP), and mining capabilities, and  counts  major  companies and organizations  like Bell, CERN, Cipal, Logitech, Nasdaq, Telefonica, Teradata, and the National September 11 Memorial and Museum among its customers. The list of flaws, which affect Pentaho Business Analytics versions 9.1 and lower, is as follows - CVE-2021-31599 ...

There is often confusion between Cloud Access Security Brokers (CASB) and SaaS Security Posture Management (SSPM) solutions, as both are designed to address security issues within SaaS applications. CASBs protect sensitive data by implementing multiple security policy enforcements to safeguard critical data. For identifying and classifying sensitive information, like Personally Identifiable Information (PII), Intellectual Property (IP), and business records, CASBs definitely help.  However, as the number of SaaS apps increase, the amount of misconfigurations and possible exposure widens and cannot be mitigated by CASBs. These solutions act as a link between users and cloud service providers and can identify issues across various cloud environments. Where CASBs fall short is that they identify breaches  after  they happen. When it comes to getting full visibility and control over the organization's SaaS apps, an SSPM solution would be the better choice, as the security ...

A novel class of vulnerabilities could be leveraged by threat actors to inject visually deceptive malware in a way that's semantically permissible but alters the logic defined by the source code, effectively opening the door to more first-party and supply chain risks. Dubbed " Trojan Source attacks ," the technique "exploits subtleties in text-encoding standards such as  Unicode  to produce source code whose tokens are logically encoded in a different order from the one in which they are displayed, leading to vulnerabilities that cannot be perceived directly by human code reviewers," Cambridge University researchers Nicholas Boucher and Ross Anderson said in a newly published paper. The  vulnerabilities  — tracked as CVE-2021-42574 and CVE-2021-42694 — affect compilers of all popular programming languages such as C, C++, C#, JavaScript, Java, Rust, Go, and Python. Compilers are programs that translate high-level human-readable source code into their lower-l...

Cybersecurity researchers disclosed details of what they say is the "largest botnet" observed in the wild in the last six years, infecting over 1.6 million devices primarily located in China, with the goal of launching distributed denial-of-service (DDoS) attacks and inserting advertisements into HTTP websites visited by unsuspecting users. Qihoo 360's Netlab security team dubbed the botnet " Pink " based on a sample obtained on November 21, 2019, owing to a large number of function names starting with "pink." Mainly targeting MIPS-based fiber routers, the botnet leverages a combination of third-party services such as GitHub, peer-to-peer (P2P) networks, and central command-and-control (C2) servers for its bots to controller communications, not to mention completely encrypting the transmission channels to prevent the victimized devices from being taken over. "Pink raced with the vendor to retain control over the infected devices, while vendor...

12 people have been detained as part of an international law enforcement operation for orchestrating ransomware attacks on critical infrastructure and large organizations that hit over 1,800 victims across 71 countries since 2019, marking the latest action against cybercrime groups. The arrests were made earlier this week on October 26 in Ukraine and Switzerland, resulting in the seizure of cash worth $52,000, five luxury vehicles, and a number of electronic devices that the agencies said are being examined to uncover new forensic evidence of their malicious activities and pursue new investigative leads. The suspects have been primarily linked to LockerGoga, MegaCortex, and Dharma ransomware, in addition to being in charge of  laundering the ransom payments  by funneling the ill-gotten Bitcoin proceeds through mixing services and cashing them out. "The targeted suspects all had different roles in these professional, highly organised criminal organisations," Europol  ...

An unidentified threat actor has been linked to a new Android malware strain that features the ability to root smartphones and take complete control over infected smartphones while simultaneously taking steps to evade detection. The malware has been named " AbstractEmu " owing to its use of code abstraction and anti-emulation checks undertaken to thwart analysis right from the moment the apps are opened. Notably, the global mobile campaign is engineered to target and infect as many devices as possible indiscriminately. Lookout Threat Labs said it found a total of 19 Android applications that posed as utility apps and system tools like password managers, money managers, app launchers, and data saving apps, seven of which contained the rooting functionality. Only one of the rogue apps, called Lite Launcher, made its way to the official Google Play Store, attracting a total of 10,000 downloads before it was purged. The apps are said to have been prominently distributed via...

Microsoft on Thursday disclosed details of a new vulnerability that could allow an attacker to bypass security restrictions in macOS and take complete control of the device to perform arbitrary operations on the device without getting flagged by traditional security solutions. Dubbed " Shrootless " and tracked as  CVE-2021-30892 , the "vulnerability lies in how Apple-signed packages with post-install scripts are installed," Microsoft 365 Defender Research Team's Jonathan Bar Or  said  in a technical write-up. "A malicious actor could create a specially crafted file that would hijack the installation process." System Integrity Protection ( SIP ) aka "rootless" is a  security feature  introduced in OS X El Capitan that's designed to protect the macOS operating system by restricting a  root user  from executing unauthorized code or performing operations that may compromise system integrity. Specifically, SIP allows modification of prote...
