COVID-19 has become an ever-present topic in our lives since the start of 2020. With this we’ve seen threat actors leveraging the pandemic with themes related to remote working, vaccination status, and back to the office surveys or general updates.…
Over the last several years, the Cybereason Nocturnus Team has been tracking different APT groups operating in the Middle East region, including two main sub-groups of the Hamas cyberwarfare division: Molerats and APT-C-23. Both groups are Arabic-speaking and politically-motivated that operate on behalf of Hamas, the Palestinian Islamic-fundamentalist movement and a terrorist organization that has controlled the Gaza strip since 2006.…
A new Traffic Direction System (TDS) we are calling Parrot TDS, using tens of thousands of compromised websites, has emerged in recent months and is reaching users from around the world. The TDS has infected various web servers hosting more than 16,500 websites, ranging from adult content sites, personal websites, university sites, and local government sites.…
Remcos RAT (Remote Access Trojan) was originally designed as a professional tool to remotely control computers. Remcos RAT is recognized as a malware family because it has been abused by hackers to secretly control victims’ devices since its first version was published on July 21, 2016.…
LOADOUT is an obfuscated VBScript-based downloader which harvests extensive information from the infected system. The harvested information is then sent to a command-and-control (C2) server. C2 server responses for LOADOUT infections delivered GRIFFON, a JavaScript-based downloader which retrieves additional JavaScript modules using HTTP or DNS and executes them in memory.…

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.…
