A man-in-the-middle (MitM) attack is an adversary’s attempt to steal information by inserting themselves between victims and their legitimate, expected destination. Threat actors combining credential phishing with man-in-the-middle attacks have been another evolution in the threat landscape. In this context, rather than setting up one fake login page, the attacker lures victims to their web server which will broker the entire authentication process between the user and the actual destination.…

Read More Ever since it first appeared in late 2021, the Raspberry Robin malware campaign has been propagating globally. A number of threat intelligence reports by vendors such as RedCanary (who named it) and Microsoft (who track it as DEV-0856/Storm-0856) have covered the malware campaign in great detail. …
After months of dormancy, Earth Longzhi, a subgroup of advanced persistent threat (APT) group APT41, has reemerged using new techniques in its infection routine. This blog entry forewarns readers of Earth Longzhi’s resilience as a noteworthy threat.
We discovered a new campaign by Earth Longzhi (a subgroup of APT41) that targets organizations based in Taiwan, Thailand, the Philippines, and Fiji.…
We found TrafficStealer abusing open container APIs in order to redirect traffic to specific websites and manipulate engagement with ads.
Our team deploys containers and containerized honeypots to monitor any unwanted activities, as well as to reinforce cloud security solutions and recommendations. While these honeypots frequently capture cryptocurrency miners trying to exploit computational resources, we recently discovered a different type of attack: a piece of software that leverages Docker containers to generate money through monetized traffic.…
We have recently discovered the first-ever evidence that attackers are exploiting Kubernetes (K8s) Role-Based Access Control (RBAC) in the wild to create backdoors. The attackers also deployed DaemonSets to take over and hijack resources of the K8s clusters they attack. Our research suggests that this campaign is actively targeting at least 60 clusters in the wild.…
With recent reports that Charming Kitten group (aka Mint Sandstorm) is actively targeting critical infrastructure in the US and other countries, we would like to share the most recent insights from Bitdefender Labs about modernization of Charming Kitten’s tactics, techniques, and procedures, including a new, previously unseen malware.…

TL;DRThe Securonix Threat Research team (STR) has recently observed a new attack campaign tracked by Securonix as OCX#HARVESTER. Some of the malicious payloads leveraged as part of the attack campaign observed appear to be related to the More_eggs malicious payloads reported earlier [1].…
ESET researchers have discovered a new Lazarus Operation DreamJob campaign targeting Linux users. Operation DreamJob is the name for a series of campaigns where the group uses social engineering techniques to compromise its targets, with fake job offers as the lure. In this case, we were able to reconstruct the full chain, from the ZIP file that delivers a fake HSBC job offer as a decoy, up until the final payload: the SimplexTea Linux backdoor distributed through an OpenDrive cloud storage account.…
Summary
Since the beginning of January 2023, the BlackBerry Threat Research and Intelligence team has been following two parallel malicious campaigns that use the same infrastructure but have different purposes.
The first campaign is related to a malvertising Google Ads Platform campaign which began several months ago and distributed fake versions of legitimate software products like AnyDesk (remote desktop software), Libre Office (an open-source office productivity software suite), TeamViewer (remote access and remote-control software), and Brave (a free and open-source web browser) among others.…
In early April, we detected a significant increase in attacks that use banking Trojans of the QBot family (aka QakBot, QuackBot, and Pinkslipbot). The malware would be delivered through e-mail letters written in different languages — variations of them were coming in English, German, Italian, and French.…

As part of our ongoing research on malware being used in the Russian-Ukrainian conflict, FortiGuard Labs has encountered a malicious spoofed document pretending to be from the Ukrainian company, Energoatom, a state-owned enterprise that operates Ukraine’s nuclear power plants.…
In this blog post, we’ll provide a detailed analysis of a malicious payload we’ve dubbed “Impala Stealer”, a custom crypto stealer which was used as the payload for the NuGet malicious packages campaign we’ve exposed in our previous post. The sophisticated campaign targeted .NET developers via NuGet malicious packages, and the JFrog Security team was able to detect and report it as part of our regular activity of exposing supply chain attacks.…

Proxyjacking has Entered the Chat | Sysdig
Did you know that you can effortlessly make a small passive income by simply letting an application run on your home computers and mobile phones? It lets others (who pay a fee to a proxy service provider) borrow your Internet Protocol (IP) address for things like watching a YouTube video that isn’t available in their region, conducting unrestricted web scraping and surfing, or browsing dubious websites without attributing the activity to their own IP.…
