A new piece of stealthy Linux malware called Shikitega has been uncovered adopting a multi-stage infection chain to compromise endpoints and IoT devices and deposit additional payloads. "An attacker can gain full control of the system, in addition to the cryptocurrency miner that will be executed and set to persist," AT&T Alien Labs  said  in a new report published Tuesday. The findings add to a growing list of Linux malware that has been found in the wild in recent months, including  BPFDoor ,  Symbiote ,  Syslogk ,  OrBit , and  Lightning Framework . Once deployed on a targeted host, the attack chain downloads and executes the Metasploit's " Mettle " meterpreter to maximize control, exploits vulnerabilities to elevate its privileges, adds persistence on the host via crontab, and ultimately launches a cryptocurrency miner on infected devices. The exact method by which the initial compromise is achieved remains unknown as yet, but what makes ...

The prolific North Korean nation-state actor known as the Lazarus Group has been linked to a new remote access trojan called  MagicRAT . The previously unknown piece of malware is said to have been deployed in victim networks that had been initially breached via successful exploitation of internet-facing VMware Horizon servers, Cisco Talos said in a report shared with The Hacker News. "While being a relatively simple RAT capability-wise, it was built with recourse to the  Qt Framework , with the sole intent of making human analysis harder, and automated detection through machine learning and heuristics less likely," Talos researchers Jung soo An, Asheer Malhotra, and Vitor Ventura  said . Lazarus Group , also known as APT38, Dark Seoul, Hidden Cobra, and Zinc, refers to a cluster of financial motivated and espionage-driven  cyber activities  undertaken by the North Korean government as a means to sidestep sanctions imposed on the country and meet its strate...

Cyberattacks on large organizations dominate news headlines. So, you may be surprised to learn that small and medium enterprises (SMEs) are actually  more frequent  targets of cyberattacks. Many SMEs understand this risk firsthand.  In a recent  survey , 58% of CISOs of SMEs said that their risk of attack was higher compared to enterprises. Yet, they don't have the same resources as enterprises – making it nearly impossible to protect their organizations from widespread and increasingly more sophisticated attacks that don't discriminate based on company size. What's their solution? Extended detection and response (XDR).  During a recent webinar, Cynet's Director of Product Strategy, George Tubin ,  and guest speaker Senior Analyst at Forrester,Allie Mellen, discussed the most serious cybersecurity challenges for SMEs and how they can benefit from XDR platforms.  Here are the four key takeaways from the  conversation .  The Bigges...

A variant of the Mirai botnet known as MooBot is co-opting vulnerable D-Link devices into an army of denial-of-service bots by taking advantage of multiple exploits. "If the devices are compromised, they will be fully controlled by attackers, who could utilize those devices to conduct further attacks such as distributed denial-of-service (DDoS) attacks," Palo Alto Networks Unit 42  said  in a Tuesday report. MooBot, first disclosed by Qihoo 360's Netlab team in September 2019, has previously targeted  LILIN digital video recorders  and  Hikvision video surveillance products  to expand its network. In the latest wave of attacks discovered by Unit 42 in early August 2022, as many as four different flaws in D-Link devices, both old and new, have paved the way for the deployment of MooBot samples. These include - CVE-2015-2051  (CVSS score: 10.0) - D-Link HNAP SOAPAction Header Command Execution Vulnerability CVE-2018-6530  (CVSS score: 9.8) -...

Networking equipment maker Zyxel has released patches for a critical security flaw impacting its network-attached storage (NAS) devices. Tracked as  CVE-2022-34747  (CVSS score: 9.8), the issue relates to a "format string vulnerability" affecting NAS326, NAS540, and NAS542 models. Zyxel credited researcher Shaposhnikov Ilya for reporting the flaw. "A format string vulnerability was found in a specific binary of Zyxel NAS products that could allow an attacker to achieve unauthorized remote code execution via a crafted UDP packet," the company  said  in an advisory released on September 6. The flaw affects the following versions - NAS326 (V5.21(AAZF.11)C0 and earlier) NAS540 (V5.21(AATB.8)C0 and earlier), and NAS542 (V5.21(ABAG.8)C0 and earlier) The disclosure comes as Zyxel previously addressed local privilege escalation and authenticated directory traversal vulnerabilities ( CVE-2022-30526 and CVE-2022-2030 ) affecting its firewall products in July. In J...

High-profile companies and local governments located primarily in Asia are the subjects of targeted attacks by a previously undocumented espionage group dubbed  Worok  that has been active since late 2020. "Worok's toolset includes a C++ loader CLRLoad, a PowerShell backdoor PowHeartBeat, and a C# loader PNGLoad that uses steganography to extract hidden malicious payloads from PNG files," ESET researcher Thibaut Passilly  said  in a new report published today. Worok is said to share overlaps in tools and interests with another adversarial collective tracked as  TA428 , with the group linked to attacks against entities spanning energy, financial, maritime, and telecom sectors in Asia as well as a government agency in the Middle East and a private firm in southern Africa. Malicious activities undertaken by the group experienced a noticeable break from May 2021 to January 2022, before resuming the next month. The Slovak cybersecurity firm assessed the group's ...

Cybersecurity researchers have offered fresh insight into a previously undocumented software control panel used by a financially motivated threat group known as TA505. "The group frequently changes its malware attack strategies in response to global cybercrime trends," Swiss cybersecurity firm PRODAFT  said  in a report shared with The Hacker News. "It opportunistically adopts new technologies in order to gain leverage over victims before the wider cybersecurity industry catches on." Also tracked under the names Evil Corp, Gold Drake, Dudear, Indrik Spider, and SectorJ04, TA505 is an aggressive  Russian cybercrime syndicate  behind the infamous Dridex banking trojan and which has been linked to a  number of ransomware campaigns  in recent years.  It's also said to be connected to the  Raspberry Robin attacks  that emerged in September 2021, with similarities uncovered between the malware and Dridex. Other notable malware families assoc...
