The cybercrime operators behind the notorious TrickBot malware have once again upped the ante by fine-tuning its techniques by adding multiple layers of defense to slip past antimalware products. “As part of that escalation, malware injections have been fitted with added protection to keep researchers out and get through security controls,” IBM Trusteer said in […]
Social engineering campaigns involving the deployment of the Emotet malware botnet have been observed using “unconventional” IP address formats for the first time in a bid to sidestep detection by security solutions. This involves the use of hexadecimal and octal representations of the IP address that, when processed by the underlying operating systems, get automatically […]
An exploration of zero-click attack surface for the popular video conferencing solution Zoom has yielded two previously undisclosed security vulnerabilities that could have been exploited to crash the service, execute malicious code, and even leak arbitrary areas of its memory. Natalie Silvanovich of Google Project Zero, who discovered and reported the two flaws last year, […]
A threat actor with potential links to an Indian cybersecurity company has been nothing if remarkably persistent in its attacks against military organizations based in South Asia, including Bangladesh, Nepal, and Sri Lanka, since at least September 2020 by deploying different variants of its bespoke malware framework. Slovak cybersecurity firm ESET attributed the highly targeted […]
The financially motivated FIN8 actor, in all likelihood, has resurfaced with a never-before-seen ransomware strain called “White Rabbit” that was recently deployed against a local bank in the U.S. in December 2021. That’s according to new findings published by Trend Micro, calling out the malware’s overlaps with Egregor, which was taken down by Ukrainian law […]
An elusive threat actor called Earth Lusca has been observed striking organizations across the world as part of what appears to be simultaneously an espionage campaign and an attempt to reap monetary profits. “The list of its victims includes high-value targets such as government and educational institutions, religious movements, pro-democracy and human rights organizations in […]
Cybersecurity teams from Microsoft on Saturday disclosed they identified evidence of a new destructive malware operation targeting government, non-profit, and information technology entities in Ukraine amid brewing geopolitical tensions between the country and Russia. “The malware is disguised as ransomware but, if activated by the attacker, would render the infected computer system inoperable,” Tom Burt, […]
The U.S. Cyber Command (USCYBERCOM) on Wednesday officially confirmed MuddyWater’s ties to the Iranian intelligence apparatus, while simultaneously detailing the various tools and tactics adopted by the espionage actor to burrow into victim networks. “MuddyWater has been seen using a variety of techniques to maintain access to victim networks,” USCYBERCOM’s Cyber National Mission Force (CNMF) […]
Apple on Wednesday rolled out software updates for iOS and iPadOS to remediate a persistent denial-of-service (DoS) issue affecting the HomeKit smart home framework that could be potentially exploited to launch ransomware-like attacks targeting the devices. The iPhone maker, in its release notes for iOS and iPadOS 15.2.1, termed it as a “resource exhaustion issue” […]
A new cross-platform backdoor called “SysJoker” has been observed targeting machines running Windows, Linux, and macOS operating systems as part of an ongoing espionage campaign that’s believed to have been initiated during the second half of 2021. “SysJoker masquerades as a system update and generates its [command-and-control server] by decoding a string retrieved from a […]
Amid renewed tensions between the U.S. and Russia over Ukraine and Kazakhstan, American cybersecurity and intelligence agencies on Tuesday released a joint advisory on how to detect, respond to, and mitigate cyberattacks orchestrated by Russian state-sponsored actors. To that end, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and National Security […]
A North Korean cyberespionage group named Konni has been linked to a series of targeted attacks aimed at the Russian Federation’s Ministry of Foreign Affairs (MID) with New Year lures to compromise Windows systems with malware. “This activity cluster demonstrates the patient and persistent nature of advanced actors in waging multi-phased campaigns against perceived high-value […]
Researchers have disclosed a novel technique by which malware on iOS can achieve persistence on an infected device by faking its shutdown process, making it impossible to physically determine if an iPhone is off or otherwise. The discovery — dubbed “NoReboot” — comes courtesy of mobile security firm ZecOps, which found that it’s possible to […]
An ongoing ZLoader malware campaign has been uncovered exploiting remote monitoring tools and a nine-year-old flaw concerning Microsoft’s digital signature verification to siphon user credentials and sensitive information. Israeli cybersecurity company Check Point Research, which has been tracking the sophisticated infection chain since November 2021, attributed it to a cybercriminal group dubbed MalSmoke, citing similarities […]
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 […]
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 […]
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, […]
Peter Parker might not be a mastermind cryptocurrency criminal, but the name Spiderman is quickly becoming more associated with the mining landscape. ReasonLabs, a leading provider of cybersecurity prevention and detection software, recently discovered a new form of malware hacking into customer computers in the guise of the latest Spiderman movie. As perhaps the most […]
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: […]
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 […]
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 […]
