Proactive Threat Hunting with A.I.

Proactive Threat Hunting helps in the early detection of new threats and in the discovery of weak spots that can be leveraged by an attacker to gain or maintain access to an infrastructure.  Traditional IOCs, combined with ATT&CK Mitre TTPs and Artificial Intelligence for discovery of new behaviors raises the bar for the attackers, helping responders to identify breaches at a very early stage, enabling them to contain and mitigate the attacks quickly and effectively.

Ursnif reloaded: tracing the latest trojan campaigns

On the 9th of October our customers started reporting the same kind of incident over the span of a few hours. The identified activity appears to be linked to the banking Trojan Ursnif, a long active malware, whose roots can be traced back to 2007 together with ZeuS and SpyEye, still with strong infection capabilities in each of its campaigns. The attack vector was a malicious email with a Word document attached.

Banks and crypto wallets: unveiling a global malware campaign using Zeus/Panda

For the past weeks our Threat Intelligence team has been following an enxtesive campaign, possibly operated by the same group, targeting a large amount of financial institutions, cyptocurrency wallets and the occasional Google and Apple accounts. The attackers target their victims both with Phishing emails, typo-squatted domains and malicious attachments that eventually lead to the installation of Zeus/Panda banking malware. The group appears to be active since at least 2015 and it’s most likely related to several campaigns identified by the security community in the past 3 years.

A dive into MuddyWater APT targeting Middle-East

MuddyWater is a threat actor that caught our attention for their extensive use of “Living off the Land” attacks in a targeted campaign aimed at the Middle East. During our investigation we reconstruct the evolution of the vectors used and how the group operates to  target their victims, evade detections and move laterally inside the compromised infrastructures.

Locky Dropper Now Comes Embedded in the Loader

We have noticed a change of behaviour in the latest spam email campaigns used by Locky. Since its first release Locky took advantage of compromised domains to download the dropper binary, while recently Locky dropper is being delivered embedded into the loader code itself. By tracking these campaigns we have also noticed that Locky’s authors have made several attempts at embedding the dropper into the loader.

Dridex Downloader Tries New Sandbox-Evasion Techniques

Dridex is currently one of the most active and widespread banking malwares. Like Locky ransomware also Dridex is dispatched through a massive spam mail campaign that uses the Necurs botnet. Our sensors have long been tracking these spam campaigns and recent captured emails contain a Word document that drops Dridex. In our latest samples we have observed a delay on execution of the downloader stage that wasn’t present before, we have further investigated to figure out whether Dridex’s authors were experimenting with new, even if basic, anti-sandbox techniques.
