ReversingLabs Malware Researcher Joseph Edwards takes a deep dive into ZetaNile, a set of open-source software trojans being used by Lazarus/ZINC.

PrivateLoader is an active malware in the loader market, used by multiple threat actors to deliver various payloads, mainly information stealer. Since our previous investigation, we keep tracking the malware to map its ecosystem and delivered payloads. Starting from this tria.ge submission, we recognized a now familiar first payload, namely PrivateLoader. However, the dropped stealer was not part of our stealer growing collection, notably including RedLine or Raccoon. Eventually SEKOIA.IO realised it was a new undocumented stealer, known as RisePro. This article aims at presenting SEKOIA.IO RisePro information stealer analysis.

Acronis’ end-of-year cyberthreats report found that the proportion of phishing attacks has risen by 1.3x, accounting for 76% of all cyber attacks

The LastPass statement on their latest breach is full of omissions, half-truths and outright lies. I’m providing the necessary context for some of their claims.

In this blog post we will dive into the latest Microsoft Exchange 0-day vulnerability, dubbed #ProxyNotShell, how it relates to other Exchange vulnerabilities and finally demonstrate how ProxyRelay can combined with ProxyNotShell, even with Extended Protection and IIS rewrite rules enabled.

Although Flash Player reached end of life for macOS in 2020, this has not stopped Shlayer operators from continuing to abuse it for malvertising campaigns.

Shlayer malware bypasses Gatekeeper security protections on macOS to execute unauthorized software without requiring approval.

While conducting routine threat hunting for macOS malware on Ad networks, I stumbled upon an unusual Shlayer sample. Upon further analysis, it became clear that this variant was different from the known Shlayer variants such as OSX/Shlayer.D, OSX/Shlayer.E, or ZShlayer. We have dubbed it OSX/Shlayer.F.

A threat actor claims to be selling public and private data of 400 million Twitter users scraped in 2021 using a now-fixed API vulnerability. They're asking $200,000 for an exclusive sale.

The recent (2022) compromise of Lastpass included email addresses, home addresses, names, and encrypted customer vaults. In this post I will demonstrate how attackers may leverage tools like Hashcat to crack an encrypted vault with a weak password.

As more and more users adopt new versions of Microsoft Office, it is likely that threat actors will turn away from VBA-based malicious documents to other formats such as XLLs or rely on exploiting newly discovered vulnerabilities to launch malicious code.

We found samples of the Raspberry Robin malware spreading in telecommunications and government office systems beginning September. The main payload itself is packed with more than 10 layers for obfuscation and is capable of delivering a fake payload once it detects sandboxing and security analytics tools.

New PolyVice ransomware is likely in use by multiple threat actors building re-branded payloads with the same custom encryption scheme.

Cluster25 researchers analyzed several campaigns (also publicly reported by CERT-AGID) that used phishing emails to spread an InfoStealer malware written in .NET through an infection chain that involves Windows Shortcut (LNK) files and Batch Scripts (BAT). Taking into account the used TTPs and extracted evidence, the attacks seem perpetrated by the same adversary (internally named AUI001).

We are working diligently to understand the scope of the incident and identify what specific information has been accessed.

Cyble Research and Intelligence Labs analyzes multiple ransomware strains created based on leaked source code of Conti Ransomware.

Meddler-in-the-Middle (MitM) phishing attacks show how threat actors find ways to get around traditional defenses and advice.

In this report, we compare the ROADSWEEP ransomware and ZEROCLEARE wiper versions used in two waves of attacks against Albanian government organizations.

CrowdStrike has uncovered a new cryptojacking campaign targeting vulnerable Docker and Kubernetes infrastructure using an obscure domain from the payload, container escape attempt and anonymized “dog” mining pools.

Called “Kiss-a-dog,” the campaign used multiple command-and-control (C2) servers to launch attacks that attempted to mine cryptocurrency, utilize user and kernel mode rootkits to hide the activity, backdoor compromised containers, move laterally in the network and gain persistence. 

The CrowdStrike Falcon® platform helps protect organizations of all sizes from sophisticated breaches, including cryptojacking campaigns such as this. 

Robot vacuum companies say your images are safe, but a sprawling global supply chain for data from our devices creates risk.
