Patching really, really matters – patching is what keeps technology solutions from becoming like big blocks of Swiss cheese, with endless security vulnerabilities punching hole after hole into critical solutions. But anyone who’s spent any amount of time maintaining systems will know that patching is often easier said than done. Yes, in some instances, you
The U.S. Cybersecurity Infrastructure and Security Agency (CISA) on Thursday warned of continued ransomware attacks aimed at disrupting water and wastewater facilities (WWS), highlighting five incidents that occurred between March 2019 and August 2021. “This activity—which includes attempts to compromise system integrity via unauthorized access—threatens the ability of WWS facilities to provide clean, potable water
A new deceptive ad injection campaign has been found leveraging an ad blocker extension for Google Chrome and Opera web browsers to sneakily insert ads and affiliate codes on websites, according to new research from cybersecurity firm Imperva. The findings come following the discovery of rogue domains distributing an ad injection script in late August
The operators behind the pernicious TrickBot malware have resurfaced with new tricks that aim to increase its foothold by expanding its distribution channels, ultimately leading to the deployment of ransomware such as Conti. The threat actor, tracked under the monikers ITG23 and Wizard Spider, has been found to partner with other cybercrime gangs known Hive0105,
Google’s Threat Analysis Group (TAG) on Thursday said it’s tracking more than 270 government-backed threat actors from more than 50 countries, adding it has approximately sent 50,000 alerts of state-sponsored phishing or malware attempts to customers since the start of 2021. The warnings mark a 33% increase from 2020, the internet giant said, with the
A now-patched critical vulnerability in OpenSea, the world’s largest non-fungible token (NFT) marketplace, could’ve been abused by malicious actors to drain cryptocurrency funds from a victim by sending a specially-crafted token, opening a new attack vector for exploitation. The findings come from cybersecurity firm Check Point Research, which began an investigation into the platform following
The maintainers of LibreOffice and OpenOffice have shipped security updates to their productivity software to remediate multiple vulnerabilities that could be weaponized by malicious actors to alter documents to make them appear as if they are digitally signed by a trusted source. The list of the three flaws is as follows — Successful exploitation of
Although organizations commonly go to great lengths to address security vulnerabilities that may exist within their IT infrastructure, an organization’s helpdesk might pose a bigger threat due to social engineering attacks. Social engineering is “the art of manipulating people so they give up confidential information,” according to Webroot. There are many different types of social
The Apache Software Foundation on Thursday released additional security updates for its HTTP Server product to remediate what it says is an “incomplete fix” for an actively exploited path traversal and remote code execution flaw that it patched earlier this week. CVE-2021-42013, as the new vulnerability is identified as, builds upon CVE-2021-41773, a flaw that
Cybersecurity researchers have detailed a new campaign that likely targets entities in Southeast Asia with a previously unrecognized Linux malware that’s engineered to enable remote access to its operators, in addition to amassing credentials and function as a proxy server. The malware family, dubbed “FontOnLake” by Slovak cybersecurity firm ESET, is said to feature “well-designed
An “aggressive” financially motivated threat actor has been identified as linked to a string of RYUK ransomware attacks since October 2018, while maintaining close partnerships with TrickBot-affiliated threat actors and using a publicly available arsenal of tools such as Cobalt Strike Beacon payloads to interact with victim networks. Cybersecurity firm Mandiant attributed the intrusions to
A high-severity code injection vulnerability has been disclosed in 23andMe’s Yamale, a schema and validator for YAML, that could be trivially exploited by adversaries to execute arbitrary Python code. The flaw, tracked as CVE-2021-38305 (CVSS score: 7.8), involves manipulating the schema file provided as input to the tool to circumvent protections and achieve code execution.
Details have emerged about a new cyber espionage campaign directed against the aerospace and telecommunications industries, primarily in the Middle East, with the goal of stealing sensitive information about critical assets, organizations’ infrastructure, and technology while remaining in the dark and successfully evading security solutions. Boston-based cybersecurity company Cybereason dubbed the attacks “Operation Ghostshell,” pointing
Cybersecurity researchers on Tuesday revealed details of a previously undocumented UEFI (Unified Extensible Firmware Interface) bootkit that has been put to use by threat actors to backdoor Windows systems as early as 2012 by modifying a legitimate Windows Boot Manager binary to achieve persistence, once again demonstrating how technology meant to secure the environment prior
A newly discovered data exfiltration mechanism employs Ethernet cables as a “transmitting antenna” to stealthily siphon highly-sensitive data from air-gapped systems, according to the latest research. “It’s interesting that the wires that came to protect the air-gap become the vulnerability of the air gap in this attack,” Dr. Mordechai Guri, the head of R&D in
In yet another indicator of how hacking groups are quick to capitalize on world events and improvise their attack campaigns for maximum impact, threat actors have been discovered impersonating Amnesty International to distribute malware that purports to be security software designed to safeguard against NSO Group’s Pegasus surveillanceware. “Adversaries have set up a phony website
A formerly unknown Chinese-speaking threat actor has been linked to a long-standing evasive operation aimed at South East Asian targets as far back as July 2020 to deploy a kernel-mode rootkit on compromised Windows systems. Attacks mounted by the hacking group, dubbed GhostEmperor by Kaspersky, are also said to have used a “sophisticated multi-stage malware
Cybersecurity researchers have disclosed an unpatched flaw in Apple Pay that attackers could abuse to make an unauthorized Visa payment with a locked iPhone by taking advantage of the Express Travel mode set up in the device’s wallet. “An attacker only needs a stolen, powered on iPhone. The transactions could also be relayed from an
Cybersecurity researchers have disclosed an unpatched security vulnerability in the protocol used by Microsoft Azure Active Directory that potential adversaries could abuse to stage undetected brute-force attacks. “This flaw allows threat actors to perform single-factor brute-force attacks against Azure Active Directory (Azure AD) without generating sign-in events in the targeted organization’s tenant,” researchers from Secureworks
A newly discovered “aggressive” mobile campaign has infected north of 10 million users from over 70 countries via seemingly innocuous Android apps that subscribe the individuals to premium services costing €36 (~$42) per month without their knowledge.
