Details have emerged about a previously undocumented and fully undetectable (FUD) PowerShell backdoor that gains its stealth by disguising itself as part of a Windows update process. "The covert self-developed tool and the associated C2 commands seem to be the work of a sophisticated, unknown threat actor who has targeted approximately 100 victims," Tomer Bar, director of security research at SafeBreach,  said  in a new report. Attributed to an  unnamed threat actor , attack chains involving the malware commence with a weaponized  Microsoft Word document  that, per the company, was uploaded from Jordan on August 25, 2022. Metadata associated with the lure document indicates that the initial intrusion vector is a LinkedIn-based spear-phishing attack, which ultimately leads to the execution of a PowerShell script via a piece of embedded macro code. "The Macro drops 'updater.vbs,' creates a scheduled task pretending to be part of a Windows update, which will ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday released two Industrial Control Systems (ICS)  advisories  pertaining to severe flaws in Advantech R-SeeNet and Hitachi Energy APM Edge appliances. This consists of three weaknesses in the R-SeeNet monitoring solution, successful exploitation of which "could result in an unauthorized attacker remotely deleting files on the system or allowing remote code execution." The list of issues, which affect R-SeeNet Versions 2.4.17 and prior, is as follows - CVE-2022-3385 and CVE-2022-3386  (CVSS scores: 9.8) - Two stack-based buffer overflow flaws that could lead to remote code execution CVE-2022-3387  (CVSS score: 6.5) - A path traversal flaw that could enable a remote attacker to delete arbitrary PDF files Patches have been made available in version  R-SeeNet version 2.4.21  released on September 30, 2022. Also published by CISA is an update to a December 2021 advisory about mult...

Both cryptocurrency and ransomware are nothing new in the digital world; both have been there for a very long time, which was enough for them to find common pieces for starting their relationship. Ransomware can be like a virtual car that works on all types of fuels, and crypto is the one that is currently most recommended. No one can argue that 2020 was the year of ransomware in the cyber world, but it wasn't due to the fact that cybercriminals chose ransomware just because they knew how to attack properly. It's because of the fact that crypto rose mostly this year, along with the new normal of the digital world. It gave them a new cause to stick to ransomware, thanks to the anonymous payments that can be made using a cryptocurrency.  How does ransomware work?  Ransomware is a malware type that encrypts the victim's files, whether it's a random user or an organization, leading to denying them access to those files on their personal devices. And the key to gaining ...

The China-aligned espionage-focused actor dubbed Winnti has set its sights on government organizations in Hong Kong as part of an ongoing campaign dubbed  Operation CuckooBees . Active since at least 2007,  Winnti  (aka APT41, Barium, Bronze Atlas, and Wicked Panda) is the name designated to a prolific cyber threat group that carries out Chinese state-sponsored espionage activity, predominantly aimed at stealing technology secrets from organizations in developed economies. The threat actor's campaigns have targeted healthcare, telecoms, high-tech, media, agriculture, and education sectors, with infection chains primarily relying on spear-phishing emails with attachments to initially break into the victims' networks. Earlier this May, Cybereason  disclosed  long-running attacks orchestrated by the group since 2019 to siphon intellectual property from technology and manufacturing companies mainly located in East Asia, Western Europe, and North America. The i...

Law enforcement authorities in France, in collaboration with Spain and Latvia, have disrupted a cybercrime ring that leveraged a hacking tool to steal cars without having to use a physical key fob. "The criminals targeted vehicles with keyless entry and start systems, exploiting the technology to get into the car and drive away," Europol  said  in a press statement. The coordinated operation, which took place on October 10, 2022, resulted in the arrest of 31 suspects from across 22 locations in the three nations, including software developers, its resellers, and the car thieves who used the tool to break into vehicles. Also confiscated by the officials as part of the arrests were criminal assets worth €1,098,500, not to mention an internet domain that allegedly advertised the service online. Per Europol, the criminals are said to have singled out keyless vehicles from two unnamed French car manufacturers. The perpetrators then used the fraudulent package to replace the ...

HelpSystems, the company behind the Cobalt Strike software platform, has released an out-of-band security update to address a remote code execution vulnerability that could allow an attacker to take control of targeted systems. Cobalt Strike is a commercial red-team framework that's mainly used for adversary simulation, but cracked versions of the software have been  actively   abused  by ransomware operators and espionage-focused advanced persistent threat (APT) groups alike. The  post-exploitation tool  consists of a team server, which functions as a command-and-control (C2) component, and a beacon, the default malware used to create a connection to the team server and drop next-stage payloads. The issue, tracked as  CVE-2022-42948 , affects Cobalt Strike version 4.7.1, and stems from an incomplete patch released on September 20, 2022, to rectify a cross-site scripting ( XSS ) vulnerability ( CVE-2022-39197 ) that could lead to remote code execution....
