PikaBot | Breaking Cybersecurity News | The Hacker News

Ukrainian entities based in Finland have been targeted as part of a malicious campaign distributing a commercial remote access trojan known as Remcos RAT using a malware loader called IDAT Loader. The attack has been attributed to a threat actor tracked by the Computer Emergency Response Team of Ukraine (CERT-UA) under the moniker UAC-0184. "The attack, as part of the IDAT Loader, used steganography as a technique," Morphisec researcher Michael Dereviashkin said in a report shared with The Hacker News. "While steganographic, or 'Stego' techniques are well-known, it is important to understand their roles in defense evasion, to better understand how to defend against such tactics." IDAT Loader , which overlaps with another loader family called Hijack Loader, has been used to serve additional payloads like DanaBot, SystemBC, and RedLine Stealer in recent months. It has also been used by a threat actor tracked as TA544 to distribute Remcos RAT and SystemBC...

The threat actors behind the PikaBot malware have made significant changes to the malware in what has been described as a case of "devolution." "Although it appears to be in a new development cycle and testing phase, the developers have reduced the complexity of the code by removing advanced obfuscation techniques and changing the network communications," Zscaler ThreatLabz researcher Nikolaos Pantazopoulos  said . PikaBot,  first documented  by the cybersecurity firm in May 2023, is a malware loader and a backdoor that can execute commands and inject payloads from a command-and-control (C2) server as well as allow the attacker to control the infected host. It is also known to halt its execution should the system's language be Russian or Ukrainian, indicating that the operators are either based in Russia or Ukraine. In recent months, both PikaBot and another loader called DarkGate have emerged as  attractive replacements  for threat actors such as  Wa...

A threat actor called Water Curupira has been observed actively distributing the  PikaBot  loader malware as part of spam campaigns in 2023. "PikaBot's operators ran phishing campaigns, targeting victims via its two components — a loader and a core module — which enabled unauthorized remote access and allowed the execution of arbitrary commands through an established connection with their command-and-control (C&C) server," Trend Micro  said  in a report published today. The activity began in the first quarter of 2023 that lasted till the end of June, before ramping up again in September. It also overlaps with  prior campaigns  that have used similar tactics to deliver QakBot, specifically those  orchestrated  by  cybercrime groups  known as TA571 and TA577. It's believed that the increase in the number of phishing campaigns related to PikaBot is the result of QakBot's takedown in August, with DarkGate emerging as another replace...

The malware loader known as PikaBot is being distributed as part of a  malvertising   campaign  targeting users searching for legitimate software like AnyDesk. "PikaBot was previously only distributed via malspam campaigns similarly to QakBot and emerged as one of the preferred payloads for a threat actor known as TA577," Malwarebytes' Jérôme Segura  said . The malware family, which  first   appeared  in early 2023, consists of a loader and a core module that allows it to operate as a backdoor as well as a distributor for other payloads. This  enables  the threat actors to gain unauthorized remote access to compromised systems and transmit commands from a command-and-control (C2) server, ranging from arbitrary shellcode, DLLs, or executable files, to other malicious tools such as Cobalt Strike. One of the threat actors leveraging PikaBot in its attacks is  TA577 , a prolific cybercrime threat actor that has, in the past, delivered ...
