The results of Fortinet Threat Intelligence Insider Latin America for the second 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, exploit of vulnerabilities and malware for steal information from users.
What are the risk areas?
· Unpatched software with critical vulnerabilities exposed to the Internet.
· Infected devices or those prone to problems of more serious infections.
· Users misusing resources, browsing dangerous sites or downloading non-legal software.
· Misleading adds promoting malware.
· IoT devices without control or adequate security policies.
In regard to the most detected vulnerabilities, collaboration systems such as Voice over Internet Protocol (VoIP) and video calls, among others that use Session Initiation Protocols (SIP) and critical services as NTP are being targeted by multiple recognition and intrusion techniques. Old vulnerabilities still being a main vector for hackers gain access to different systems.
What are the risk areas?
· Collaboration solutions with operational problems due to denial of service attacks.
· Unauthorized access by third parties to VoIP solutions with the aim of making extortion calls or abusing the use of resources such as long-distance calls.
· Access to corporate networks through servers with SIP-based services, taking advantage of multiple attack vectors.
· Evidence of platforms without updates or with weak passwords.
· Reconnaissance of internal networks.
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.
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.
· Ransomware and criptojacking infections.
· Involvement of the infected devices in DDoS or SPAM attacks, denying the entire company’s access to services.
· Password or business-critical information theft.
· Illegal activities in the dark web.
The report also reveals the most common infections in Latin America and the Caribbean:
· Malware infections generating unwanted adds or redirection to sites infected with malware.
· Trojans or backdoors that allow the attacker to take full control of the infected devices
· Viruses or infections of advanced malware for the exfiltration of information such as passwords and users, among others.
· Malware for the exploitation of common vulnerabilities that allow attackers’ remote access to infected devices.
· Riskware, use of free software or of unrecognized origin that offers user characteristics such as protection, but also enables the possibility of infections.
Is a computer virus with attack, worm and Trojan characteristics that affect Windows computers and can be considered a serious computer threat if antivirus protection is not available
Is a Trojan, a type of malware that performs activities 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 (DDoS) attacks, and running/terminating processes.
This indicates detection of SIP Register Brute Force attempts. The attack consists of multiple SIP register requests intended to conduct a brute force attack, launched at a rate of about 5 times in 10 seconds.
SIPVicious is a SIP scanner. The signature detects for SIP requests from the scanner at a rate of 200 per second. The rate can be adjusted in the CLI or GUI to suit your needs
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.
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 Mirai Botnet. System Compromise: Remote attackers can gain control of vulnerable systems.
This botnet is a type of malware bot that may perform many malicious tasks, such as downloading and executing additional malware, receiving commands from a control server and relaying specific information.
