In recent months, Allot Secure has detected 200% increase in direct requests to malicious IP addresses. Prior to June 2020, most of the Internet connection requests identified and blocked as malicious by Allot NetworkSecure were in the form of domains or URLs, only ~2-4% were direct to IP address requests. Suddenly in the second half of 2020 their volumes started increasing dramatically. By February 2021, direct to IP requests accounted for 14% of all blocks. This increase in attempts to connect to malicious IPS was caused by Android Trojans and other malware trying to connect to their command & control (C2C) servers, phishing, spamming, DDoS attacks and password cracking and login attempts.
How are Users Infected?
Direct to IP requests can originate in all the same ways a regular URL website request does. Users may receive them as links in emails or messaging platforms. The two most proliferous Android Trojans were Joker and Cerberus. Cerberus and Joker both infect users via email attachments,
malicious online advertisements, social engineering, deceptive applications, and scam websites. Joker also managed to spread via infected mobile apps that managed to slip past Google’s rigorous testing to reach the platform’s official app store. Many types of malware include instructions to establish connections directly with an IP controlled by the cybercriminals. Communication with IPs is often done in the background, without the user’s knowledge.
Spammers and Phishers can replace malicious domains with direct IP addresses of their host sites. The recent increase in direct to IP requests could also be caused by malware attempting to connect with an external command and control (C&C) server. Malicious code often includes instructions to
connect directly with an IP controlled by cybercriminals to receive further instructions, exfiltrate sensitive data or carry out a ransomware, botnet or DDoS attack.
Mobile Trojans (Cerberus, Joker), are capable of intercepting private messages and login credentials, silently signing users up for premium SMS services etc.), hijacking accounts, fraudulent purchases, and text messages.
