Ukraine's Computer Emergency Response Team (CERT-UA) has warned of Belarusian state-sponsored hackers targeting its military personnel and related individuals as part of a phishing campaign mounted amidst Russia's military invasion of the country. "Mass  phishing emails  have recently been observed targeting private 'i.ua' and 'meta.ua' accounts of Ukrainian military personnel and related individuals," the CERT-UA  said . "After the account is compromised, the attackers, by the IMAP protocol, get access to all the messages." Subsequently, the attacks leverage the contact information stored in the victim's address book to propagate the phishing messages to other targets. The Ukrainian government attributed the activities to a threat actor tracked as UNC1151, a Minsk-based group whose "members are officers of the Ministry of Defence of the Republic of Belarus." In a follow-up  update , the agency said the nation-state group a...

Cybersecurity researchers have taken the wraps off a previously undocumented and stealthy custom malware called SockDetour that targeted U.S.-based defense contractors with the goal of being used as a secondary implant on compromised Windows hosts. "SockDetour is a backdoor that is designed to remain stealthily on compromised Windows servers so that it can serve as a backup backdoor in case the primary one fails," Palo Alto Networks' Unit 42 threat intelligence  said  in a report published Thursday. "It is difficult to detect, since it operates filelessly and socketlessly on compromised Windows servers." Even more concerningly, SockDetour is believed to have been used in attacks since at least July 2019, based on a compilation timestamp on the sample, implying that the backdoor successfully managed to slip past detection for over two-and-a-half years. The attacks have been attributed to a threat cluster it tracks as  TiltedTemple  (aka DEV-0322 by Microsof...

Cybersecurity agencies from the U.K. and the U.S. have laid bare a new malware used by the Iranian government-sponsored advanced persistent threat (APT) group in attacks targeting government and commercial networks worldwide. "MuddyWater actors are positioned both to provide stolen data and accesses to the Iranian government and to share these with other malicious cyber actors," the agencies  said . The joint advisory comes courtesy of the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), the U.S. Cyber Command Cyber National Mission Force (CNMF), and the U.K.'s National Cyber Security Centre (NCSC). The cyberespionage actor was  outed this year  as conducting malicious operations as part of Iran's Ministry of Intelligence and Security (MOIS) targeting a wide range of government and private-sector organizations, including telecommunications, defense, local government, and oil and natural gas sectors, in Asia, Afric...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

The Russian government on Thursday warned of cyber attacks aimed at domestic critical infrastructure operators, as the country's full-blown invasion of Ukraine enters the second day. In addition to cautioning of the "threat of an increase in the intensity of computer attacks," Russia's National Computer Incident Response and Coordination Center  said  that the "attacks can be aimed at disrupting the functioning of important information resources and services, causing reputational damage, including for political purposes." "Any failure in the operation of [critical information infrastructure] objects due to a reason that is not reliably established, first of all, should be considered as the result of a computer attack," the agency added. Furthermore, it notified of possible influence operations undertaken to "form a negative image of the Russian Federation in the eyes of the world community," echoing a  similar alert  released by the U...

The modular Windows crimeware platform known as TrickBot formally shuttered its infrastructure on Thursday after reports emerged of its  imminent retirement  amid a lull in its activity for almost two months, marking an end to one of the most persistent malware campaigns in recent years. "TrickBot is gone... It is official now as of Thursday, February 24, 2022. See you soon... or not," AdvIntel's CEO Vitali Kremez  tweeted . "TrickBot is gone as it has become inefficient for targeted intrusions." Attributed to a Russia-based criminal enterprise called  Wizard Spider , TrickBot started out as a financial trojan in late 2016 and is a derivative of another banking malware called  Dyre  that was dismantled in November 2015. Over the years, it morphed into a veritable Swiss Army knife of malicious capabilities, enabling threat actors to steal information via  web injects  and drop additional payloads. TrickBot's activities took a noticeable h...

Cisco has released software updates to address four security vulnerabilities in its software that could be weaponized by malicious actors to take control of affected systems. The most critical of the flaws is  CVE-2022-20650  (CVSS score: 8.8), which relates to a command injection flaw in the NX-API feature of Cisco NX-OS Software that stems from a lack of sufficient input validation of user-supplied data. "An attacker could exploit this vulnerability by sending a crafted HTTP POST request to the NX-API of an affected device," Cisco said. "A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying operating system." The flaw impacts Nexus 3000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, and Nexus 9000 Series Switches in standalone NX-OS mode running Cisco NX-OS Software that have the NX-API feature enabled. Also patched are two high-severity den...

TrickBot, the infamous Windows crimeware-as-a-service (CaaS) solution that's used by a variety of threat actors to deliver next-stage payloads like ransomware, appears to be undergoing a transition of sorts, with no new activity recorded since the start of the year. The lull in the malware campaigns is "partially due to a big shift from Trickbot's operators, including working with the operators of Emotet," researchers from Intel 471  said  in a report shared with The Hacker News. The last set of attacks involving TrickBot were registered on December 28, 2021, even as command-and-control (C2) infrastructure associated with the malware has continued to serve additional plugins and  web injects  to infected nodes in the botnet. Interestingly, the decrease in the volume of the campaigns has also been accompanied by the TrickBot gang working closely with the  operators of Emotet , which witnessed a resurgence late last year after a 10-month-long break following ...
