PyPI Package | Breaking Cybersecurity News | The Hacker News

Cybersecurity researchers have discovered a new bunch of malicious packages on the npm package registry that are designed to exfiltrate sensitive developer information. Software supply chain firm Phylum, which first identified the "test" packages on July 31, 2023, said they "demonstrated increasing functionality and refinement," hours after which they were removed and re-uploaded under different, legitimate-sounding package names. While the end goal of the undertaking is not clear, it's suspected to be a highly targeted campaign  aimed at the cryptocurrency sector  based on references to modules such as "rocketrefer" and "binarium." All the packages were published by the npm user malikrukd4732. A common feature across all the modules is the ability to launch JavaScript ("index.js") that's equipped to exfiltrate valuable information to a remote server. "The index.js code is spawned in a child process by the preinstall.j...

A threat actor by the name  Lolip0p  has uploaded three rogue packages to the Python Package Index (PyPI) repository that are designed to drop malware on compromised developer systems. The packages – named  colorslib  (versions 4.6.11 and 4.6.12),  httpslib  (versions 4.6.9 and 4.6.11), and  libhttps  (version 4.6.12) – by the author between January 7, 2023, and January 12, 2023. They have since been yanked from PyPI but not before they were cumulatively downloaded over 550 times. The modules come with identical setup scripts that are designed to invoke PowerShell and run a malicious binary (" Oxzy.exe ") hosted on Dropbox, Fortinet  disclosed  in a report published last week. The executable, once launched, triggers the retrieval of a next-stage, also a binary named  update.exe , that runs in the Windows temporary folder ("%USER%\AppData\Local\Temp\"). update.exe is flagged by antivirus vendors on VirusTotal as an information ...

Threat actors have published yet another round of malicious packages to Python Package Index (PyPI) with the goal of delivering information-stealing malware on compromised developer machines. Interestingly, while the malware goes by a variety of names like ANGEL Stealer, Celestial Stealer, Fade Stealer, Leaf $tealer, PURE Stealer, Satan Stealer, and @skid Stealer, cybersecurity company Phylum found them all to be copies of  W4SP Stealer . W4SP Stealer primarily functions to siphon user data, including credentials, cryptocurrency wallets, Discord tokens, and other files of interest. It's created and published by an actor who goes by the aliases BillyV3, BillyTheGoat, and billythegoat356. "For some reason, each deployment appears to have simply tried to do a find/replace of the W4SP references in exchange for some other seemingly arbitrary name," the researchers  said  in a report published earlier this week. The 16 rogue modules are as follows: modulesecurity, inform...

Security operations centers (SOCs) are under pressure from both sides: threats are growing more complex and frequent, while security budgets are no longer keeping pace. Today's security leaders are expected to reduce risk and deliver results without relying on larger teams or increased spending. At the same time, SOC inefficiencies are draining resources. Studies show that up to half of all alerts are false positives, with some reports citing false positive rates as high as 99 percent . This means highly trained analysts spend a disproportionate amount of time chasing down harmless activity, wasting effort, increasing fatigue, and raising the chance of missing real threats. In this environment, the business imperative is clear: maximize the impact of every analyst and every dollar by making security operations faster, smarter, and more focused.
