A financially-motivated threat actor notorious for its cryptojacking attacks has leveraged a revised version of their malware to target cloud infrastructures using vulnerabilities in web server technologies, according to new research. Deployed by the China-based cybercrime group  Rocke , the Pro-Ocean cryptojacking malware now comes with improved rootkit and worm capabilities, as well as harbors new evasion tactics to sidestep cybersecurity companies' detection methods, Palo Alto Networks' Unit 42 researchers  said  in a Thursday write-up. "Pro-Ocean uses known vulnerabilities to target cloud applications," the researchers detailed. "In our analysis, we found Pro-Ocean targeting Apache ActiveMQ ( CVE-2016-3088 ), Oracle WebLogic ( CVE-2017-10271 ) and Redis (unsecure instances)." "Once installed, the malware kills any process that uses the CPU heavily, so that it's able to use 100% of the CPU and mine Monero efficiently." First documented...

A "severe" vulnerability in GNU Privacy Guard (GnuPG)'s Libgcrypt encryption software could have allowed an attacker to write arbitrary data to the target machine, potentially leading to remote code execution. The flaw, which affects version 1.9.0 of libgcrypt, was discovered on January 28 by Tavis Ormandy of Project Zero, a security research unit within Google dedicated to finding zero-day bugs in hardware and software systems. No other versions of Libgcrypt are affected by the vulnerability. "There is a  heap buffer overflow  in libgcrypt due to an incorrect assumption in the block buffer management code," Ormandy  said . "Just decrypting some data can overflow a heap buffer with attacker controlled data, no verification or signature is validated before the vulnerability occurs." GnuPG addressed the weakness almost immediately within a day after disclosure, while urging users to  stop using  the vulnerable version. The latest version can be dow...

Google Project Zero on Thursday disclosed details of a new security mechanism that Apple quietly added to iOS 14 as a countermeasure to prevent attacks that were recently found to leverage zero-days in its messaging app. Dubbed " BlastDoor ," the improved sandbox system for iMessage data was disclosed by Samuel Groß, a Google Project Zero researcher tasked with studying zero-day vulnerabilities in hardware and software systems. "One of the major changes in iOS 14 is the introduction of a new, tightly sandboxed 'BlastDoor' service which is now responsible for almost all parsing of untrusted data in iMessages," Groß  said . "Furthermore, this service is written in Swift, a (mostly) memory safe language which makes it significantly harder to introduce classic memory corruption vulnerabilities into the code base." The development is a consequence of a  zero-click exploit  that leveraged an Apple iMessage flaw in iOS 13.5.1 to get around security p...

The pressure on small to medium-sized enterprises to protect their organizations against cyberthreats is astronomical. These businesses face the same threats as the largest enterprises, experience the same (relative) damages and consequences when breaches occur as the largest enterprises but are forced to protect their organizations with a fraction of the resources as the largest enterprises.  Cybersecurity company Cynet just released findings from a survey of 200 CISOs in charge of small security teams ( Download here ) to shine "a spotlight into the challenges of small security teams everywhere." In addition to better understanding the challenges these CISOs face, the 2021 Survey of CISOs with Small Security Teams delves into the strategies CISOs will employ to ensure their organizations are protected from the ongoing onslaught of cyber threats - all while saddled with limited budgets and headcount. The survey findings will also be presented in a live webinar,  register...

A "persistent attacker group" with alleged ties to Hezbollah has retooled its malware arsenal with a new version of a remote access Trojan (RAT) to break into companies worldwide and extract valuable information. In a  new report  published by the ClearSky research team on Thursday, the Israeli cybersecurity firm said it identified at least 250 public-facing web servers since early 2020 that have been hacked by the threat actor to gather intelligence and steal the company's databases. The orchestrated intrusions hit a slew of companies located in the U.S., the U.K., Egypt, Jordan, Lebanon, Saudi Arabia, Israel, and the Palestinian Authority, with a majority of the victims representing telecom operators (Etisalat, Mobily, Vodafone Egypt), internet service providers (SaudiNet, TE Data), and hosting and infrastructure service providers (Secured Servers LLC, iomart). First documented in 2015,  Volatile Cedar  (or Lebanese Cedar) has been known to penetrate a large n...
