New Golang-based Linux Malware Targeting eCommerce Websites

November 22, 2021Ravie Lakshmanan
Weaknesses in e-commerce portals are being exploited to deploy a Linux backdoor as well as a credit card skimmer that’s capable of stealing payment information from compromised websites. “The attacker started with automated e-commerce attack probes, testing for dozens of weaknesses in common online store platforms,” researchers from Sansec Threat Research  said  in an analysis. “After a day and a half, the attacker found a file upload vulnerability in one of the store’s plugins.” The name of the affected vendor was not revealed. The initial foothold was then leveraged to upload a malicious web shell and alter the server code to siphon customer data. Additionally, the attacker delivered a Golang-based malware called ” linux_avp ” that serves as a backdoor to execute commands remotely sent from a command-and-control server hosted in Beijing. Upon execution, the program is designed to remove itself from the disk and camouflage as a ” ps -ef

Hackers Exploiting ProxyLogon and ProxyShell Flaws in Spam Campaigns

November 22, 2021Ravie Lakshmanan
Threat actors are exploiting ProxyLogon and ProxyShell exploits in unpatched Microsoft Exchange Servers as part of an ongoing spam campaign that leverages stolen email chains to bypass security software and deploy malware on vulnerable systems. The findings come from Trend Micro following an investigation into a number of intrusions in the Middle East that culminated in the distribution of a never-before-seen loader dubbed SQUIRRELWAFFLE. First publicly  documented  by Cisco Talos, the attacks are believed to have commenced in mid-September 2021 via laced Microsoft Office documents. “It is known for sending its malicious emails as replies to pre-existing email chains, a tactic that lowers a victim’s guard against malicious activities,” researchers Mohamed Fahmy, Sherif Magdy, Abdelrhman Sharshar  said  in a report published last week. “To be able to pull this off, we believe it involved the use of a chain of both ProxyLogon and ProxyShell exploits.” ProxyLo

Facebook Postpones Plans for E2E Encryption in Messenger, Instagram Until 2023

November 21, 2021Ravie Lakshmanan
Meta, the parent company of Facebook, Instagram, and WhatsApp, disclosed that it doesn’t intend to roll out default end-to-end encryption (E2EE) across all its messaging services until 2023, pushing its original plans by at least a year. “We’re taking our time to get this right and we don’t plan to finish the global rollout of end-to-end encryption by default across all our messaging services until sometime in 2023,” Meta’s head of safety, Antigone Davis,  said  in a post published in The Telegraph over the weekend. The new scheme, described as a “three-pronged approach,” aims to employ a mix of non-encrypted data across its apps as well as account information and reports from users to improve safety and combat abuse, noting that the goal is to deter illegal behavior from happening in the first place, giving users more control, and actively encouraging users to flag harmful messages. Meta had previously  outlined  plans to be “fully end-to-en

RedCurl Corporate Espionage Hackers Return With Updated Hacking Tools

November 20, 2021Ravie Lakshmanan
A corporate cyber-espionage hacker group has resurfaced after a seven-month hiatus with new intrusions targeting four companies this year, including one of the largest wholesale stores in Russia, while simultaneously making tactical improvements to its toolset in an attempt to thwart analysis. “In every attack, the threat actor demonstrates extensive red teaming skills and the ability to bypass traditional antivirus detection using their own custom malware,” Group-IB’s Ivan Pisarev  said . Active since at least November 2018, the Russian-speaking  RedCurl hacking group  has been linked to 30 attacks to date with the goal of corporate cyber espionage and document theft aimed at 14 organizations spanning construction, finance, consulting, retail, insurance, and legal sectors and located in the U.K., Germany, Canada, Norway, Russia, and Ukraine. The threat actor uses an array of established hacking tools to infiltrate its targets and steal internal corporate documentat

November 20, 2021Ravie Lakshmanan
A threat actor with ties to North Korea has been linked to a prolific wave of credential theft campaigns targeting research, education, government, media and other organizations, with two of the attacks also attempting to distribute malware that could be used for intelligence gathering. Enterprise security firm Proofpoint  attributed  the infiltrations to a group it tracks as  TA406 , and by the wider threat intelligence community under the monikers  Kimsuky  ( Kaspersky ), Velvet Chollima ( CrowdStrike ), Thallium ( Microsoft ), Black Banshee ( PwC ), ITG16 ( IBM ), and the Konni Group ( Cisco Talos ). Policy experts, journalists and nongovernmental organizations (NGOs) were targeted as part of weekly campaigns observed between from January through June 2021, Proofpoint researchers Darien Huss and Selena Larson disclosed in a technical report detailing the actor’s tactics, techniques, and procedures (TTPs), with the attacks spread across North America, Russia, China, and South

11 Malicious PyPI Python Libraries Caught Stealing Discord Tokens and Installing Shells

November 19, 2021Ravie Lakshmanan
Cybersecurity researchers have uncovered as many as 11 malicious Python packages that have been cumulatively downloaded more than 41,000 times from the Python Package Index (PyPI) repository, and could be exploited to steal Discord access tokens, passwords, and even stage dependency confusion attacks. The Python packages have since been removed from the repository following responsible disclosure by DevOps firm JFrog — importantpackage / important-package pptest ipboards owlmoon DiscordSafety trrfab 10Cent10 / 10Cent11 yandex-yt yiffparty Two of the packages (“importantpackage,” “10Cent10,” and their variants) were found obtaining a reverse shell on a compromised machine, giving the attacker full control over the system. Two other packages “ipboards” and “trrfab” masqueraded as legitimate dependencies designed to be automatically imported by taking advantage of a technique called  dependency confusion  or namespace confusion.
