  • EclecticIQ cybersecurity researchers have uncovered a cyberespionage operation dubbed “Operation FlightNight” targeting Indian government entities and energy companies. 

    The attackers, likely state-sponsored, leveraged a modified version of the open-source information stealer HackBrowserData to steal sensitive data.

    EclecticIQ identified that the attackers used Slack channels, a popular communication platform, as exfiltration points.Β 

    These channels were named “FlightNight,” giving the operation its name.

    Data Breach:

    The attackers successfully infiltrated multiple government agencies responsible for communication, IT, and national defense.

    Additionally, private energy companies were compromised, with details about financial documents, employee information, and even oil and gas drilling activities stolen.Β 

    A staggering 8.81 GB of data was exfiltrated, potentially aiding future intrusions.

    The attackers used a trick to get victims to install malware. 

    They sent emails disguised as invitations from the Indian Air Force. 

    These emails contained an ISO file, which appeared to be a harmless archive. 

    However, when the victim opened the ISO file, it actually launched a shortcut file (LNK) disguised as a PDF document.Β 

    Clicking the LNK file unknowingly activated the malware.

    The malware then exfiltrated confidential documents, private emails, and cached web browser data.

    The Malware’s Work:

    The stolen data included documents, emails, and browsing history.  

    Instead of sending the stolen data directly to the attackers, the malware uploaded it to channels on a communication platform called Slack. 

    To make it appear like normal activity on the network and to help the attackers avoid detection.

    Overlaps between new and earlier malware campaign.

    The attackers modified an existing tool called HackBrowserData to add new features like document theft and communication through Slack.  

    Analysis of the code confirmed these modifications. 

    The malware also used a specific naming scheme for temporary files and targeted certain file types like documents and databases to steal data faster.

    Finding The Victims:

    The malware made a big mistake by storing the keys needed to access and control the Slack channels directly in its code. 

    EclecticIQ researchers found these keys and used them to access the Slack channels where the stolen data was uploaded.Β Β 

    These channels contained information for the researchers:

    • A list of victims – who was targeted by the attack.
    • File paths – exactly where the stolen data came from on the victim’s computer.
    • Timestamps – when the data was stolen.
    • Download URLs – unique links that allow anyone with the link to download the stolen data!

    Another mistake was testing the connectivity over Slack workspaces.

    This helped researchers understand even more about the attacker’s setup, including details about the Slack team and the bots used to communicate.

    Recommendation/Mitigation

    • Disable the “remember me” feature in web browser and turn off automatic username completion.
    • Two-factor authentication (2FA)  adds an extra layer of security by requiring a second verification code in addition to password when logging in.
    • Be cautious with ISO files
    • Command-line auditing can help track suspicious activity related to LNK files, which can launch malware.
    • Watch for unusual amounts of data being sent to unknown Slack channels.

  • The notorious WarzoneRAT malware has made a comeback, despite the FBI’s recent efforts to dismantle its operations.

    Initially detected in 2018, WarzoneRAT was disrupted by the FBI in mid-February when they seized the malware’s infrastructure and arrested two individuals linked to the cybercrime scheme.

    However, ThreatMon’s recent advertisement for WarZoneRAT v3, with its enhanced features, indicates that the threat actors are far from giving up.

    Cybersecurity experts at Cyble Research & Intelligence Labs (CRIL) have uncovered a new campaign that leverages tax-themed spam emails to spread the WarzoneRAT (Avemaria) malware, a Remote Administration Tool (RAT) known for its remote control capabilities and ability to execute malicious actions under the command of a remote server.

    Infection Tactics: The LNK and HTA Files

    The infection begins when unsuspecting users open an email with the subject “taxorganizer2023” and execute an attached archive file.

    This file contains a deceptive shortcut file, “taxorganizer2023.png.lnk,” which appears to be an image but is, in fact, a malicious LNK file.

    When executed, it triggers a PowerShell command to download and extract a ZIP file, leading to the execution of an HTA file.

    This HTA file then retrieves a PowerShell script in memory, which downloads a VBScript file from a remote server, ultimately deploying the WarzoneRAT malware.

  • Android devices are popular among hackers due to the platform’s extensive acceptance and open-source nature.

    However, it has a big attack surface with over 2.5 billion active Android devices all over the world.

    It also poses challenges when it comes to prompt vulnerability patching due to its fragmented ecosystem that consists of different hardware vendors and delayed software updates.

    Malware distribution, surveillance, and unauthorized financial gain, or any other malicious purpose are some examples of how cybercriminals take advantage of these loopholes in security.

    Recently, Google unveiled the Kernel Address Sanitizer (KASan) to strengthen the Android firmware and beyond.

    Android Firmware And Beyond

    KASan (Kernel Address Sanitizer) has broad applicability across firmware targets. Incorporating KASan-enabled builds into testing and fuzzing can proactively identify memory corruption vulnerabilities and stability issues before deployment on user devices.

    Adapt to the changing threat landscape effortlessly with Perimeter 81’s cloud-based, unified network security platform.

    Google has already leveraged KASan on firmware targets, leading to the discovery and remediation of over 40 memory safety bugs, some critically severe, through proactive vulnerability detection.

    Address Sanitizer (ASan) is a compiler instrumentation tool that identifies invalid memory access bugs like out-of-bounds, use-after-free, and double-free errors during runtime.Β 

    For user-space targets, enabling ASan is straightforward with the -fsanitize=address option. However, for bare-metal code built with none system targets like arm-none-eabi, there’s no default runtime support. 

    The -fsanitize=kernel-address option exposes an interface to provide custom KASan runtime implementations, like the Linux kernel’s routines.

    KASan’s core idea is to instrument memory access operations like loads, stores, and memory copy functions to verify the validity of destination/source regions. 

    It only allows access to valid regions tracked in a shadow memory area, where each byte represents the state (allocated, freed, accessible bytes) of a fixed-size memory region. 

    Upon detecting an invalid access, KASan reports the violation.

    Enabling KASan for bare-metal targets requires implementing instrumentation routines to check region validity during memory operations, report violations, and manage shadow memory to track the state of covered regions.

    For Bare-Metal Firmware, Enabling KASan

    Here below we have mentioned all the sequential steps:-

    • KASan shadow memory
    • Implement a KASan runtime
    • Memory access check
    • Shadow memory management
    • Covering global variables
    • Memory copy functions
    • Avoiding false positives for noreturn functions
    • Hook heap memory allocation routines

    For the usage of KASan on bare-metal code, one should employ -fsanitize=kernel-address option of the compiler and -asan-mapping-offset to indicate the location of shadow memory, -asan-stack/globals=1 to cover stack/global variables and -asan-instrumentation-with-call-threshold=0 for outlining checks against code bloat.

    In addition, strategies such as leveraging Rust (a memory-safe language) are being advanced in order to proactively guard against memory vulnerabilities in the Android system.
