Understanding banking Trojan techniques can help detect other activities of financially motivated threat groups.

Our blog entry provides a look at an attack involving the LV ransomware on a Jordan-based company from an intrusion analysis standpoint

Threat actor RomCom RAT is now targeting Ukrainian military institutions. Known to deploy spoofed versions of popular software Advanced IP Scanner, once exposed, RomCom RAT switched to PDF Filler, another popular application, which indicates the group behind it is actively developing new capabilities.

ESET researchers recently identified a new version of the Android malware FurBall being used in a Domestic Kitten campaign conducted by the APT-C-50 group. The Domestic Kitten campaign is known to conduct mobile surveillance operations against Iranian citizens and this new FurBall version is no different in its targeting. Since June 2021, it has been distributed as a translation app via a copycat of an Iranian website that provides translated articles, journals, and books. The malicious app was uploaded to VirusTotal where it triggered one of our YARA rules (used to classify and identify malware samples), which gave us the opportunity to analyze it.

See how this tool—created by a sophisticated and seemingly unknown threat actor—uses the unique approach of disguising itself as part of a Windows update.

BianLian is a financially motivated threat actor that targets a wide range of industries. It uses the exotic programming language “Go” to encrypt files with unusual speed.

There are many security solutions available today that rely on the Extended Berkeley Packet Filter (eBPF) features of the Linux kernel to monitor kernel functions. Such a paradigm shift in the latest monitoring technologies is being driven by a variety of reasons

We analyzed a QAKBOT-related case leading to a Brute Ratel C4 and Cobalt Strike payload that can be attributed to the threat actors behind the Black Basta ransomware.

ESET researchers analyzed previously undocumented custom backdoors and cyberespionage tools deployed in Israel by the POLONIUM APT group.

At most 15% of the approximately 820,000 PostgreSQL servers listening on the Internet require encryption. In fact, only 36% even support encryption. This puts PostgreSQL servers well behind the rest of the Internet in terms of security. In comparison, according to Google, over 96% of page loads in Chrome on a Mac are encrypted. The top 100 websites support encryption, and 97 of those default to encryption.

This post explores some of the TTPs employed by a threat actor who was observed deploying ShadowPad during an incident response engagement.

New research shows how third-party apps could be exploited to infiltrate these sensitive workplace tools.

In June 2022, FortiGuard Labs encountered IoT malware samples with SSH-related strings, something not often seen in other IoT threat campaigns. What piqued our interest more was the size of the code referencing these strings in relation to the code used for DDoS attacks, which usually comprises most of the code in other variants.

Flubot is an Android based malware that has been distributed in the past 1.5 years in
Europe, Asia and Oceania affecting thousands of devices of mostly unsuspecting victims.
Like the majority of Android banking malware, Flubot abuses Accessibility Permissions and Services
in order to steal the victim’s credentials, by detecting when the official banking application
is open to show a fake web injection, a phishing website similar to the login form of the banking
application. An important part of the popularity of Flubot is due to the distribution
strategy used in its campaigns, since it has been using the infected devices to send
text messages, luring new victims into installing the malware from a fake website.
In this article we detail its development over time and recent developments regarding
its disappearance, including new features and distribution campaigns.

We compare the targeting and business models of the Conti and LockBit ransomware groups using data analysis approaches. This will be presented in full at the 34th Annual FIRST Conference on June 27, 2022.

Since the last quarter of 2020 MuddyWater has mantained a “long-term” infection campaign targeting Middle East countries. We have gathered samples from November 2020 to January 2022, and due to the recent samples found, it seems that this campaign might still be currently active. The latest campaigns of the Muddy Water threat group, allegedly sponsored by the Iranian government and linked to the Iranian revolutionary guard (the main armed forces of the Iranian government), could be framed within the dynamics of maintaining Iran’s regional sovereignty.

Attacker targets bugs in a popular web application graphical interface development tool.

A group of academic researchers from the University of Hamburg in Germany has discovered that mobile devices leak identifying information about their owners via Wi-Fi probe requests.

The Lyceum APT group is targeting Middle East organizations with DNS hijacking attack using a new .NET-based malware.

Symbiote is a new Linux malware we discovered that acts in a parasitic nature, infecting other running processes to inflict damage on machines.
