Threat actors leveraged a cloud video hosting service to carry out a supply chain attack on more than 100 real estate websites operated by Sotheby’s Realty that involved injecting malicious skimmers to steal sensitive personal information. “The attacker injected the skimmer JavaScript codes into video, so whenever others import the video, their websites get embedded
Trojanized installers of the Telegram messaging application are being used to distribute the Windows-based Purple Fox backdoor on compromised systems. That’s according to new research published by Minerva Labs, describing the attack as different from intrusions that typically take advantage of legitimate software for dropping malicious payloads. “This threat actor was able to leave most
Microsoft, over the weekend, rolled out a fix to address an issue that caused email messages to get stuck on its Exchange Server platforms due to what it blamed on a date validation error at around the turn of the year. “The problem relates to a date check failure with the change of the new
Cybersecurity researchers have offered a detailed glimpse into a system called DoubleFeature that’s dedicated to logging the different stages of post-exploitation stemming from the deployment of DanderSpritz, a full-featured malware framework used by the Equation Group. DanderSpritz came to light on April 14, 2017, when a hacking group known as the Shadow Brokers leaked the
A never-before-seen China-based targeted intrusion adversary dubbed Aquatic Panda has been observed leveraging critical flaws in the Apache Log4j logging library as an access vector to perform various post-exploitation operations, including reconnaissance and credential harvesting on targeted systems. Cybersecurity firm CrowdStrike said the infiltration, which was ultimately foiled, was aimed at an unnamed “large academic
A previously unknown rootkit has been found setting its sights on Hewlett-Packard Enterprise’s Integrated Lights-Out (iLO) server management technology to carry out in-the-wild attacks that tamper with the firmware modules and completely wipe data off the infected systems. The discovery, which is the first instance of real-world malware in iLO firmware, was documented by Iranian
An ongoing crypto mining campaign has upgraded its arsenal while adding new defense evasion tactics that enable the threat actors to conceal the intrusions and fly under the radar, new research published today has revealed. Since first detected in 2019, a total of 84 attacks against its honeypot servers have been recorded to date, four
The Apache Software Foundation (ASF) on Tuesday rolled out fresh patches to contain an arbitrary code execution flaw in Log4j that could be abused by threat actors to run malicious code on affected systems, making it the fifth security shortcoming to be discovered in the tool in the span of a month. Tracked as CVE-2021-44832,
A number of security flaws have been uncovered in a networking component in Garrett Metal Detectors that could allow remote attackers to bypass authentication requirements, tamper with metal detector configurations, and even execute arbitrary code on the devices. “An attacker could manipulate this module to remotely monitor statistics on the metal detector, such as whether
Cybersecurity researchers have disclosed details of an evasive malware campaign that makes use of valid code signing certificates to sneak past security defenses and stay under the radar with the goal of deploying Cobalt Strike and BitRAT payloads on compromised systems. The binary, a loader, has been dubbed “Blister” by researchers from Elastic Security, with
Ransomware groups continue to evolve their tactics and techniques to deploy file-encrypting malware on compromised systems, notwithstanding law enforcement’s disruptive actions against the cybercrime gangs to prevent them from victimizing additional companies. “Be it due to law enforcement, infighting amongst groups or people abandoning variants altogether, the RaaS [ransomware-as-a-service] groups dominating the ecosystem at this
Apple recently fixed a security vulnerability in the macOS operating system that could be potentially exploited by a threat actor to “trivially and reliably” bypass a “myriad of foundational macOS security mechanisms” and run arbitrary code. Security researcher Patrick Wardle detailed the discovery in a series of tweets on Thursday. Tracked as CVE-2021-30853 (CVSS score:
Cybersecurity agencies from Australia, Canada, New Zealand, the U.S., and the U.K. on Wednesday released a joint advisory in response to widespread exploitation of multiple vulnerabilities in Apache’s Log4j software library by nefarious adversaries. “These vulnerabilities, especially Log4Shell, are severe,” the intelligence agencies said in the new guidance. “Sophisticated cyber threat actors are actively scanning
China’s internet regulator, the Ministry of Industry and Information Technology (MIIT), has suspended a partnership with Alibaba Cloud, the cloud computing subsidiary of e-commerce giant Alibaba Group, for six months for failing to promptly report a critical security vulnerability affecting the broadly used Log4j logging library. The development was reported by Reuters and South China
Transportation industry and government agencies related to the sector are the victims of an ongoing campaign since July 2020 by a sophisticated and well-equipped cyberespionage group in what appears to be yet another uptick in malicious activities that are “just the tip of the iceberg.” “The group tried to access some internal documents (such as
Researchers have disclosed security vulnerabilities in handover, a fundamental mechanism that undergirds modern cellular networks, which could be exploited by adversaries to launch denial-of-service (DoS) and man-in-the-middle (MitM) attacks using low-cost equipment. The “vulnerabilities in the handover procedure are not limited to one handover case only but they impact all different handover cases and scenarios
The issues with Log4j continued to stack up as the Apache Software Foundation (ASF) on Friday rolled out yet another patch — version 2.17.0 — for the widely used logging library that could be exploited by malicious actors to stage a denial-of-service (DoS) attack. Tracked as CVE-2021-45105 (CVSS score: 7.5), the new vulnerability affects all
Cybersecurity researchers have discovered an entirely new attack vector that enables adversaries to exploit the Log4Shell vulnerability on servers locally by using a JavaScript WebSocket connection. “This newly-discovered attack vector means that anyone with a vulnerable Log4j version on their machine or local private network can browse a website and potentially trigger the vulnerability,” Matthew
Meta Platforms on Thursday revealed it took steps to deplatform seven cyber mercenaries that it said carried out “indiscriminate” targeting of journalists, dissidents, critics of authoritarian regimes, families of opposition, and human rights activists located in over 100 countries, amid mounting scrutiny of surveillance technologies. To that end, the company said it alerted 50,000 users
Cybersecurity researchers have demonstrated a new attack technique that makes it possible to leverage a device’s Bluetooth component to directly extract network passwords and manipulate traffic on a Wi-Fi chip. The novel attacks work against the so-called “combo chips,” which are specialized chips that are equipped to handle different types of radio wave-based wireless communications,
Meta Platforms, the company formerly known as Facebook, has announced that it’s expanding its bug bounty program to start rewarding valid reports of scraping vulnerabilities across its platforms as well as include reports of scraping data sets that are available online. “We know that automated activity designed to scrape people’s public and private data targets
Romanian cybersecurity technology company Bitdefender on Monday revealed that attempts are being made to target Windows machines with a novel ransomware family called Khonsari as well as a remote access Trojan named Orcus by exploiting the recently disclosed critical Log4j vulnerability.
