Tax season can be a stressful time for many people, and it comes as no surprise that every year threat actors look to capitalize on this by using a variety of new tactics to exploit their targets’ accounts and systems.…
For the Lazarus threat actor, financial gain is one of the prime motivations, with a particular emphasis on the cryptocurrency business. As the price of cryptocurrency surges, and the popularity of non-fungible token (NFT) and decentralized finance (DeFi) businesses continues to swell, the Lazarus group’s targeting of the financial industry keeps evolving.…
Morphisec Labs has detected a new wave of Remcos trojan infection. The theme of the phishing emails is again financial, this time as payment remittances sent from financial institutions. The attacker lures a user to open a malicious Excel file that contains “confidential information” which starts the infection chain.…
Hacking forums often double up as underground marketplaces where cybercriminals buy, rent, and sell all kinds of malicious illegal products, including software, trojans, stealers, exploits, and leaked credentials. Malware-as-a-service has contributed substantially to the growth of ransomware and phishing attacks (among other attack types) in the past year, as they lower the technical barrier to entry for criminals to carry out attacks.…
Geopolitical tensions often make headlines and present a golden opportunity for threat actors to exploit the situation, especially those targeting high-profile victims. In the past month while the Russian invasion of Ukraine was unfolding, Check Point Research (CPR) has observed advanced persistent threat (APT) groups around the world launching new campaigns, or quickly adapting ongoing ones to target victims with spear-phishing emails using the war as a lure.…
Spearphishing crafted with industry-specific terms derived from intelligence gathering techniques to trick a recipient into opening a file is especially difficult to identify. This is especially true when an adversary has knowledge of how a business works and the processes that underpin it. Using this knowledge, a lure can be crafted that takes advantage of these day-to-day processes – for example, settling the cost of a fuel transaction.…

Emotet (also known as Geodo and Heodo) is a banking trojan, but it is also a modular malware that can be used to download other malware as Trickbot and IcedID [8, 9, 13].…
This post describes the technical analysis of a new campaign detected by Intezer’s research team, which initiates attacks with a phishing email that uses conversation hijacking to deliver IcedID.
The underground economy is constantly evolving with threat actors specializing in specific fields. One field that has bloomed in the last few years is initial access brokers.…
Malicious email and phishing scams are usually topical and follow a pattern of current events, and they typically are crafted around calendar and/or trending issues as attackers realize that victims are interested in all things relevant to the moment. Threat actors are aware that not all recipients will bite, but some will, hence the origin of the term “phishing.”…
A Cobalt Strike Cybercrime Syndicate and the Ransomware Hackers’ Favorite Weapon
On March 9, the Cybersecurity and Infrastructure Security Agency (CISA) and the U.S. Secret Service issued an updated alert about the Conti ransomware group, encouraging organizations to review their advisory and apply the recommended mitigations.…
The post-pandemic world has seen cryptocurrencies and blockchain products in general catapult in valuation and adoption. “Web3”, “DeFi”, and “NFT” have become household terms and the sector is growing so fast that people and businesses are pouring in with dollar signs in their eyes and high hopes to get a piece of the pie.…
Information stealing malware is on the rise. Cyble Research Labs recently discovered a new malware dubbed “AvD crypto stealer” on a cybercrime forum. Upon further investigation, however, we observed that this does not function as a Crypto Stealer. This is, in fact, a disguised variant of well-known Clipper malware that can read and edit any text copied by the victim i.e.…
ESET researchers discovered a still-ongoing campaign using a previously undocumented Korplug variant, which they named Hodur due to its resemblance to the THOR variant previously documented by Unit 42 in 2020. In Norse mythology, Hodur is Thor’s blind half-brother, who is tricked by Loki into killing their half-brother Baldr.…

OverviewBlackBerry Threat Intelligence has identified a new Ransomware-as-a-Service (Raas) family, and tracked its lineage to its probable beta stage release.…
The DirtyMoe malware is deployed using various kits like PurpleFox or injected installers of Telegram Messenger that require user interaction. Complementary to this deployment, one of the DirtyMoe modules expands the malware using worm-like techniques that require no user interaction.
This research analyzes this worming module’s kill chain and the procedures used to launch/control the module through the DirtyMoe service.…
I came across a fairly interesting VBS-based DanaBot downloader the other day, and I figured it was worth doing a quick write-up on the obfuscation scheme and a few of the other TPPs I observed. The social engineering pretext used in this campaign was interesting as it leveraged an “unclaimed property” themed lure and required user interaction to deliver the first stage payload.…
Over recent months, the CrowdStrike Falcon® OverWatch™ team has tracked an ongoing, widespread intrusion campaign leveraging bundled .msi installers to trick victims into downloading malicious payloads alongside legitimate software. These payloads and scripts were used to perform reconnaissance and ultimately download and execute NIGHT SPIDER’s Zloader trojan, as detailed in CrowdStrike CROWDSTRIKE FALCON® INTELLIGENCE™ Premium reporting.…
