Cybercriminals Abuse Open-Source Tools To Target Africa’s Financial Sector

Source: https://unit42.paloaltonetworks.com/cybercriminals-attack-financial-sector-across-africa/

This threat campaign involves cybercriminals leveraging open-source tools to conduct attacks targeting the financial sector across Africa. The campaign was reported by Unit 42, a reputable cybersecurity research group, and shared on the InfoSecNews subreddit. Although specific affected software versions or vulnerabilities are not detailed, the mention of 'rce' (remote code execution) in the newsworthiness assessment indicates that attackers may be exploiting remote code execution vulnerabilities or techniques to compromise systems. The use of open-source tools suggests that attackers are utilizing publicly available software frameworks or utilities, potentially to automate attacks, evade detection, or exploit known weaknesses in financial institutions' infrastructure. The campaign is recent (published June 2025) and has a medium severity rating, indicating a moderate level of threat. No known exploits in the wild have been reported yet, and discussion levels on Reddit are minimal, suggesting that the campaign is either emerging or not widely publicized. The lack of specific technical details such as exploited CVEs or attack vectors limits the granularity of the analysis, but the focus on Africa's financial sector implies targeted attacks on banking systems, payment platforms, or financial service providers, likely aiming at financial gain through fraud, data theft, or disruption.

TP-Link VN020 F3v(T) TT_V6.2.1021) - DHCP Stack Buffer Overflow

The TP-Link VN020 F3v(T) TT_V6.2.1021 firmware contains a critical vulnerability in its DHCP service, specifically a stack-based buffer overflow triggered by malformed DHCP DISCOVER packets. The exploit targets the DHCP server running on UDP port 67, which processes broadcast DISCOVER packets without any authentication. The vulnerability arises primarily from the handling of the hostname DHCP option, where the router allocates a 64-byte buffer but the exploit sends a 127-byte hostname, causing a stack overflow and memory corruption. Additional vectors include malformed length fields in DHCP options and vendor-specific option parsing edge cases that confuse the DHCP parser, further facilitating memory corruption. The exploit is remote and requires no authentication or user interaction, making it highly accessible to attackers on the same network segment or potentially from the internet if the DHCP server is exposed. The provided exploit code, written in C, crafts a malicious DHCP DISCOVER packet with carefully constructed options to trigger the overflow and cause the DHCP service to crash, resulting in denial of service. The exploit attempts multiple sends and detects success by the absence of a DHCP response, indicating a crash. This vulnerability is identified as CVE-2024-11237 and affects hardware version 1.0 of the VN020-F3v(T) routers, particularly those supplied by Tunisian ISPs Tunisie Telecom and Topnet. No patches or mitigations are currently linked, and no known exploits in the wild have been reported yet. The exploit code is detailed and includes low-level socket programming for Windows, demonstrating the attack vector and payload construction.
