The results of Fortinet Threat Intelligence Insider Latin America for the third quarter of 2019 reveal the continuous increasing of malware, exploits and botnet activity in Latin America and the Caribbean. The main activities include unwanted adds, criptojacking, IoT intrusions, exploit of vulnerabilities and malware for steal information from users.
What are the risk areas?
In regard to the most detected vulnerabilities, DoublePulsar, the backdoor used by the WannaCry ransomware, is still a mechanism for distributing malware in Latin America. Considering it takes advantage of already resolved vulnerabilities, its continuous use evidences the vast software footprint without updates in the region, affecting companies and individuals alike.
Different variations of exploits for ransomware are still very active in Latin America.
How to defend from such multi-pronged attacks?
Botnets still raising and evidence that the common problems with IoT devices continue. Default or weak passwords are the main infection vector for Mirai botnet. Millions of devices are connected and controlled for increase infections and Denial of Services attacks. Botnets are evolving and today are able to infect not only consumers but business IoT devices for use these as proxy for anonymize transactions of the dark market.
During the third quarter of 2019, a growing number of WIFICAM attempts were detected in Latin America, an attack that aims to take control of IP cameras. Another sign of the risk that IoT devices run without proper protection from the network.
What are the implications for compromised IoT devices?
The report also reveals the most common infections in Latin America and the Caribbean:
Is classified as a type of Riskware. Riskware is any potentially unwanted application that is not classified as malware, but may utilize system resources in an undesirable or annoying manner, and/or may pose a security risk
Is classified as a trojan. A trojan is a type of malware that performs activities without the user’s knowledge. These activities commonly include establishing remote access connections.
is classified as a trojan. A trojan is a type of malware that performs activites without the user’s knowledge. These 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.
This indicates detection of DoublePulsar Backdoor. Backdoor trojans have the capability to connect remote hosts and perform actions against the compromised system. The DoublePulsar Backdoor was revealed by the Shadow Brokers leaks in March 2017 and was used in the WannaCry ransomware attack in May 2017.
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.
It indicates detection of anonymous SSL ciphers negotiation. Anonymous key exchange suites may have a higher chance of Man-in-the-middle attacks.
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.
This indicates that a system might be infected by BadRabbit Botnet. BadRabbit is a file-encrypting ransomware.
This indicates detection of network traffic outbound originating from a computer infected with the W32/Conficker worm, also known as W32.Downadup and W32.Conficker. To spread, this worm exploits the Server Service Vulnerability (CVE-2008-4250), as written in the Microsoft Security Bulletin MS08-067.
