The results of Fortinet Threat Intelligence Insider Latin America for the fourth quarter of 2019 reveal the continuous increasing of malware, exploits and botnet activity in Latin America and the Caribbean. In the last quarter of the year, the region suffered more than 9 billion attempts to attack, totaling 85 billion in 2019.
The report also reveals the most common infections in Latin America and the Caribbean:
As we have seen throughout the year, DoublePulsar, the backdoor used by the WannaCry ransomware, is still a mechanism for distributing malware in the region. Considering it takes advantage of already resolved vulnerabilities, its continuous use evidences the vast software footprint without updates in Latin America, affecting companies and individuals alike. DoublePulsar is mainly targeted to banks and financial service companies.
The Emotet botnet (aimed at attacking mostly banks) reappears prominently in FortiGuard detections for the fourth quarter, and Latin America provides a 45% presence of this botnet globally.
Emotet is a Trojan malware that targets Windows platform. It contacts Command and Control servers via HTTP or HTTPS requests. A remote attacker can issue commands to the malware to perform different operations. Emotet can download and install additional malware such as ransomware.
FortiGuard detected relevant threats aimed at Cryptocurrency in Latin America and the Caribbean this fourth quarter of 2019. Here are some examples of this trend:
Different variations of malware, trojans and exploits for ransomware are still very active in Latin America.
How to defend from such multi-pronged attacks?
W32/Sramler.A!worm is classified as an Internet worm. Internet worm has the functionality to spread to other systems using NetBIOS/SMB, SMTP, MSN Messenger, P2P applications, or Mobile network.
W32/Midgare.NFV!tr is classified as a trojan. Its activities commonly include establishing remote access connections, capturing keyboard input, collecting system information, downloading/uploading files, dropping other malware into the infected system, performing denial-of-service (DoS) attacks, and running/terminating processes.
W32/Bancos.CFR!tr is classified as a trojan. Its activities commonly include establishing remote access connections, capturing keyboard input, collecting system information, downloading/uploading files, dropping other malware into the infected system, performing denial-of-service (DoS) attacks, and running/terminating processes.
SIPVicious.svcrack.Brute.Force.Login This indicates detection of an attempted brute force login from SIPVicious svcrack. SIPVicious is a SIP scanner. Remote attackers can gain access to the service provided by the vulnerable systems.
Generic.DNS.Tunnel.Detection.Variant.A This indicates detection of suspicious traffics that might be from a DNS Tunnel. DNS tunnels are proxy tools that can tunnel data over DNS to bypass firewall policy. Some malware and APT attacks have used DNS tunnels to communicate with C&C servers.
UPnP.SSDP.M.Search.Anomaly This indicates detection of an attempt scan using UPnP SSDP M-Search packets. Simple Service Discovery Protocol (SSDP) is a network protocol for advertisement and discovery of network services information. SSDP is the basis of the discovery protocol, Universal Plug and Play (UPnP). SSDP uses HTTP over UDP to announce the establishment or withdrawal of services information to the multicast group.
Sora.Botnet This indicates that a system might be infected by a Sora Botnet. Sora is an IoT malware which targets embedded systems.
Zeroaccess.Botnet This indicates a system might be infected by ZeroAccess botnet. System Compromise: Remote attackers can gain control of vulnerable systems.
Andromeda.Botnet Andromeda is a botnet that is used to distribute malware with different capabilities, depending on the command given by its command-and-control (C&C) server. The toolkit for this botnet can be obtained on the Internet underground and is constantly being updated
