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 generic detection for a Key-logger/Botnet/Downloader trojan. Since this is a generic detection, malware that are detected as W32/Agent.AJFK!tr may have varying behaviour.
Is classified as a downloader trojan. Downloader Trojan has the capability to download other malicious files or an updated version of itself.
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.
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).
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.
This indicates an attack attempt against an UDP Amplification flaw on the Memcached protocol. The vulnerability is due to an error in the vulnerable application when handling a series of maliciously crafted requests. An attacker can exploit this to cause a denial of service condition on the affected machine via maliciously crafted requests.
This indicates that a system might be infected by Mirai Botnet. System Compromise: Remote attackers can gain control of vulnerable systems.
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 a system might be infected by ZeroAccess botnet. System Compromise: Remote attackers can gain control of vulnerable systems.
