The notorious  Emotet botnet  has been linked to a new wave of malspam campaigns that take advantage of password-protected archive files to drop CoinMiner and Quasar RAT on compromised systems. In an  attack chain  detected by Trustwave SpiderLabs researchers, an invoice-themed ZIP file lure was found to contain a nested self-extracting (SFX) archive, the first archive acting as a conduit to launch the second. While phishing attacks like these traditionally require persuading the target into opening the attachment, the cybersecurity company said the campaign sidesteps this hurdle by making use of a batch file to automatically supply the password to unlock the payload. The first SFX archive file further makes use of either a PDF or Excel icon to make it appear legitimate, when, in reality, it contains three components: the password-protected second SFX RAR file, the aforementioned batch script which launches the archive, and a decoy PDF or image. "The execution ...

The decentralized file system solution known as IPFS is becoming the new "hotbed" for hosting phishing sites, researchers have warned. Cybersecurity firm Trustwave SpiderLabs, which disclosed specifics of the spam campaigns, said it identified no less than 3,000 emails containing IPFS phishing URLs as an attack vector in the last three months. IPFS , short for InterPlanetary File System, is a peer-to-peer (P2P) network to store and share files and data using cryptographic hashes, instead of URLs or filenames, as is observed in a traditional client-server approach. Each hash forms the basis for a unique content identifier ( CID ). The idea is to create a resilient distributed file system that allows data to be stored across multiple computers. This would allow information to be accessed without having to rely on third parties such as cloud storage providers, effectively making it resistant to censorship. "Taking down phishing content stored on IPFS can be difficult ...

As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...
