Researchers Hacked EV Car Chargers To Execute Arbitrary Code

By CyberMrfu3k -
EVs face significant cyber risks due to their reliance on interconnected systems and the increasing number of public charging stations, which often lack robust security measures.  Vulnerabilities in EV software and charging infrastructure can expose vehicles to malware, unauthorized access, and potential control by hackers. During Pwn2Own Automotive 2024 in Tokyo, cybersecurity researchers hacked  EV car chargers  to execute arbitrary code. Researchers Hacked EV Car Chargers At the Pwn2Own Automotive 2024 event, researchers exploited three EV chargers:-  Autel MaxiCharger (MAXI US AC W12-L-4G) ChargePoint Home Flex JuiceBox 40 Smart EV Charging Station  They executed arbitrary code via Bluetooth while focusing on the Autel MaxiCharger, and this uncovered the “CVE-2024-23958,” “CVE-2024-23959,” and “CVE-2024-23967”  vulnerabilities . The features of the charger include WiFi, Ethernet, Bluetooth, 4G LTE, RFID, LCD touchscreen, RS485, and a USB-C port. Its har...

Qilin Ransomware

By CyberMrfu3k -

The Qilin ransomware group has been using a new tactic and deploys a custom stealer to steal account credentials stored in Google Chrome browser. The credential-harvesting techniques has been observed by the Sophos X-Ops team during incident response engagements and marks an alarming change on the ransomware scene.

Attack overview:-

  • The attack that Sophos researchers analyzed started with Qilin gaining access to a network using compromised credentials for a VPN portal that lacked multi-factor authentication (MFA).   The breach was followed by 18 days of dormancy, suggesting the possibility of Qilin buying their way into the network from an initial access broker (IAB). Possibly, Qilin spent time mapping the network, identifying critical assets, and conducting reconnaissance. After the first 18 days, the attackers moved laterally to a domain controller and modified Group Policy Objects (GPOs) to execute a PowerShell script (‘IPScanner.ps1’) on all machines logged into the domain network.
  • The script, executed by a batch script (‘logon.bat’) that was also included in the GPO, was designed to collect credentials stored in Google Chrome.
  • The batch script was configured to run (and trigger the PS script) every time a user logged into their machine, while stolen credentials were saved on the ‘SYSVOL’ share under the names ‘LD’ or ‘temp.log.’

  • After sending the files to Qilin’s command and control (C2) server, the local copies and related event logs were wiped, to conceal the malicious activity. Eventually, Qilin deployed their ransomware payload and encrypted data on the compromised machines.
  • Another GPO and a separate batch file (‘run.bat’) were used to download and execute the ransomware across all machines in the domain.

Ninjutsu Project Hey everyone. Hope you all are doing good. Today I came across a post in Linkedin by Hasan , a Red team Penetration tester. It's as follows I started exploring and came to know about this distribution. A Windows based pentesting distribution!!  Sound exciting right? Within few minutes i ended up downloading the OS (17gb -_- ) Don't forget to visit their official blog and support the developer if you like his work.

Fog Ransomware

‛Fog’ Ransomware Rolls in to Target many Sectors. A new group of hackers is encrypting data in virtual machines, leaving ransom notes, and calling it a day. A new ransomware operation has been performing old-fashioned ransomware attacks, locking up data in virtual environments to earn quick payouts. Attack Vectors • Fog attacks typically begin with stolen virtual private network (VPN) credentials, an increasingly popular means of initial access into sizable organizations. The group has exploited two different VPN gateway vendors thus far, which Arctic Wolf has declined to name. • In one case, for example, Fog passed the hash to compromise administrator accounts in its target’s network. It then used the accounts to establish a remote desktop protocol (RDP) connection with Windows servers running the Hyper-V hypervisor and Veeam data protection software. • Other common Fog tactics, techniques, and procedures (TTPs) include credential stuffing, using native Windows and open-source tools l...

New PIXHELL Attack Exploits Screen Noise to Exfiltrates Data from Air-Gapped Computers

By CyberMrfu3k -

Security researchers have unveiled new techniques that allow attackers to exfiltrate sensitive data from air-gapped computers, which are systems physically isolated from unsecured networks. Despite air gaps being a strong security measure, these attacks demonstrate that determined adversaries can still find ways to breach such systems. Dr. Mordechai Guri and his team at Ben-Gurion University in Israel have published multiple papers detailing various  covert channels  that can be used to leak data from air-gapped systems. Their latest  research focuses  on exploiting computer components’ electromagnetic, acoustic, thermal, and optical emanations to transmit data to nearby receivers. One attack, dubbed  RAMBO  (Radiation of Air-gapped Memory Bus for Offense), exploits electromagnetic emissions from a computer’s RAM to leak data. Malware can generate controlled radio signals that encode stolen information by manipulating memory access patterns. Using a softwar...
