The cybercriminal group Lazarus, and particularly its subgroup Bluenoroff, has a history of attacking financial organizations in Asia and Latin America. There seems to be a resurgence of activity from the group, and recent events show how their tools and techniques have evolved. We discovered that they successfully planted their backdoor into several machines of financial institutions across Latin America.Read More
We spotted two variants of activities from hacking group Outlaw. The script used in the first version of its bot has two functionalities: the miner and Haiduc-based dropper. The second variant of the code, distributed by the bot, was mainly designed to brute force and further exploit the Microsoft Remote Desktop Protocol and cloud administration cPanel in order to escalate the privileges.Read More
Discovered by Trend Micro in 2014, the banking Trojan Emotet has been brought back to life by malware authors last year with its own spamming module that has allowed it to spread, target new industries and regions, and evade sandbox and malware analysis techniques. This year, we examined Emotet’s activities to learn more about how this modular malware wreaks havoc: We did a comprehensive research on Emotet’s artifacts — 8,528 unique URLs, 5,849 document droppers, and 571 executables collected between June 1, 2018 and September 15, 2018 — to discover Emotet’s infrastructure as well as possible attribution information.Read More
This month’s round of updates, which fixes 63 bugs, includes a patch for a zero-day vulnerability (CVE-2018-8589) that is already being used in malicious attacks.Read More
Cybercriminals have become more and more creative and efficient in their efforts to successfully bypass network security. Reports of unauthorized network intrusions that have compromised enterprise security, resources, and data, plague experts on a day-to-day basis, and will continue to do so if not prevented by a more efficient detection system or method. Currently, attackers use polymorphism, encryption, and obfuscation, among other techniques, to automate and increase variants in an attempt to evade traditional intrusion detection methods such as rule-based techniques.
To address these growing number of network threats and keep abreast with the changing sophistication of network intrusion methods, Trend Micro looked into network flow clustering — a method that leverages the power of machine learning in strengthening current intrusion detection techniques.Read More
