Lazarus Exploits Typos to Sneak PyPI Malware into Dev Systems

Lazarus Exploits Typos to Sneak PyPI Malware into Dev Systems

Feb 29, 2024 Malware / Endpoint Security
The notorious North Korean state-backed hacking group Lazarus uploaded four packages to the Python Package Index (PyPI) repository with the goal of infecting developer systems with malware. The packages, now taken down, are  pycryptoenv ,  pycryptoconf ,  quasarlib , and  swapmempool . They have been collectively downloaded 3,269 times, with pycryptoconf accounting for the most downloads at 1,351. "The package names pycryptoenv and pycryptoconf are similar to pycrypto, which is a Python package used for encryption algorithms in Python," JPCERT/CC researcher Shusei Tomonaga  said . "Therefore, the attacker probably prepared the malware-containing malicious packages to target users' typos in installing Python packages." The disclosure comes days after Phylum  uncovered  several rogue packages on the npm registry that have been used to single out software developers as part of a campaign codenamed Contagious Interview. An interesting commonality between the t
Open-Source Xeno RAT Trojan Emerges as a Potent Threat on GitHub

Open-Source Xeno RAT Trojan Emerges as a Potent Threat on GitHub

Feb 27, 2024 Malware / Network Security
An "intricately designed" remote access trojan (RAT) called  Xeno RAT  has been made available on GitHub, making it easily accessible to other actors at no extra cost. Written in C# and compatible with Windows 10 and Windows 11 operating systems, the open-source RAT comes with a "comprehensive set of features for remote system management," according to its developer, who goes by the name moom825. It includes a SOCKS5 reverse proxy and the ability to record real-time audio, as well as incorporate a hidden virtual network computing ( hVNC ) module along the lines of  DarkVNC , which allows attackers to gain remote access to an infected computer. "Xeno RAT is developed entirely from scratch, ensuring a unique and tailored approach to remote access tools," the developer  states  in the project description. Another notable aspect is that it has a builder that enables the creation of bespoke variants of the malware.  It's worth noting that moom825 is a
6 Ways to Simplify SaaS Identity Governance

6 Ways to Simplify SaaS Identity Governance

Feb 21, 2024SaaS Security / Identity Management
With SaaS applications now making up the vast majority of technology used by employees in most organizations, tasks related to identity governance need to happen across a myriad of individual SaaS apps. This presents a huge challenge for centralized IT teams who are ultimately held responsible for managing and securing app access, but can't possibly become experts in the nuances of the native security settings and access controls for hundreds (or thousands) of apps. And, even if they could, the sheer volume of tasks would easily bury them. Modern IT teams need a way to orchestrate and govern SaaS identity governance by engaging the application owners in the business who are most familiar with how the tool is used, and who needs what type of access.  Nudge Security is a  SaaS security and governance solution  that can help you do just that, with automated workflows to save time and make the process manageable at scale. Read on to learn how it works. 1 . Discover all SaaS apps used b
LockBit Ransomware Group Resurfaces After Law Enforcement Takedown

LockBit Ransomware Group Resurfaces After Law Enforcement Takedown

Feb 26, 2024 Dark Web / Threat Intelligence
The threat actors behind the LockBit ransomware operation have resurfaced on the dark web using new infrastructure, days after an international law enforcement exercise  seized control  of its servers. To that end, the notorious group has moved its data leak portal to a new .onion address on the TOR network, listing 12 new victims as of writing. The administrator behind LockBit, in a  lengthy follow-up message , said some of their websites were confiscated by most likely exploiting a critical PHP flaw tracked as CVE-2023-3824, acknowledging that they didn't update PHP due to "personal negligence and irresponsibility." "I realize that it may not have been this CVE, but something else like 0-day for PHP, but I can't be 100% sure, because the version installed on my servers was already known to have a known vulnerability, so this is most likely how the victims' admin and chat panel servers and the blog server were accessed," they noted. They also cla

Authorities Claim LockBit Admin "LockBitSupp" Has Engaged with Law Enforcement

Authorities Claim LockBit Admin "LockBitSupp" Has Engaged with Law Enforcement

Feb 25, 2024 Cybercrime / Ransomware
LockBitSupp, the individual(s) behind the persona representing the LockBit ransomware service on cybercrime forums such as Exploit and XSS, "has engaged with law enforcement," authorities said. The development comes following the  takedown  of the prolific ransomware-as-a-service (RaaS) operation as part of a coordinated international operation codenamed Cronos. Over 14,000 rogue accounts on third-party services like Mega, Protonmail, and Tutanota used by the criminals have been shuttered. "We know who he is. We know where he lives. We know how much he is worth. LockbitSupp has engaged with law enforcement," according to a  message  posted on the now-seized (and offline) dark web data leak site. The move has been  interpreted  by long-term watchers of LockBit as an attempt to create suspicion and sow the seeds of distrust among affiliates, ultimately undermining trust in the group within the cybercrime ecosystem. According to research published by Analyst1 in A
Apple Unveils PQ3 Protocol - Post-Quantum Encryption for iMessage

Apple Unveils PQ3 Protocol - Post-Quantum Encryption for iMessage

Feb 22, 2024 Quantum Computing / Encryption
Apple has announced a new post-quantum cryptographic protocol called  PQ3  that it said will be integrated into iMessage to secure the messaging platform against future attacks arising from the threat of a practical quantum computer. "With compromise-resilient encryption and extensive defenses against even highly sophisticated quantum attacks, PQ3 is the first messaging protocol to reach what we call Level 3 security — providing protocol protections that surpass those in all other widely deployed messaging apps," Apple  said . The iPhone maker described the protocol as "groundbreaking," "state-of-the-art," and as having the "strongest security properties" of any cryptographic convention deployed at scale. PQ3 is the latest security guardrail erected by Apple in iMessage after it switched from  RSA  to Elliptic Curve cryptography ( ECC ), and by protecting encryption keys on devices with the Secure Enclave in 2019. While the current algorith
A New Age of Hacktivism

A New Age of Hacktivism

Feb 22, 2024 Hacktivism / Information Warfare
In the past 2 years, we have observed a significant surge in hacktivism activity due to ongoing wars and geopolitical conflicts in various regions. Since the war against Ukraine began, we have witnessed a notable mobilization of non-state and state-backed actors alike, forming new groups or joining existing hacker collectives.  We understand hacktivism as a form of computer hacking that is done to further the goals of political or social  activism 1 . While  activism  describes a normal, non-disruptive use of the Internet in order to support a specific cause (online petitions, fundraising, coordinating activities),  hacktivism  includes operations that use hacking techniques with the intent to disrupt but not to cause serious harm (e.g., data theft, website defacements, redirects, Denial-of-Service attacks). Cyber operations that inherit a willingness or intent to cause harm to physical property, severe economic damage or loss of life would be referred to as  cyberterrorism, 2, 3  Th
U.S. Offers $15 Million Bounty to Hunt Down LockBit Ransomware Leaders

U.S. Offers $15 Million Bounty to Hunt Down LockBit Ransomware Leaders

Feb 22, 2024 Ransomware / Cybercrime
The U.S. State Department has announced monetary rewards of up to $15 million for information that could lead to the identification of key leaders within the LockBit ransomware group and the arrest of any individual participating in the operation. "Since January 2020, LockBit actors have executed over 2,000 attacks against victims in the United States, and around the world, causing costly disruptions to operations and the destruction or exfiltration of sensitive information," the State Department  said . "More than $144 million in ransom payments have been made to recover from LockBit ransomware events." The development comes as a sweeping law enforcement operation led by the U.K. National Crime Agency (NCA)  disrupted  LockBit, a Russia-linked ransomware gang that has been active for more than four years, wreaking havoc on business and critical infrastructure entities around the world. Ransomware-as-a-service (RaaS) operations like LockBit and others work by e

Signal Introduces Usernames, Allowing Users to Keep Their Phone Numbers Private

Feb 21, 2024 Secure Communication / Anonymity
End-to-end encrypted (E2EE) messaging app Signal said it's piloting a new feature that allows users to create unique usernames (not to be confused with profile names) and keep the phone numbers away from prying eyes. "If you use Signal, your phone number will no longer be visible to everyone you chat with by default," Signal's Randall Sarafa  said . "People who have your number saved in their phone's contacts will still see your phone number since they already know it." Setting a new username requires account holders to provide two or more numbers at the end of it (e.g., axolotl.99) in an effort to keep them "egalitarian and minimize spoofing." Usernames can be changed any number of times, but it's worth noting that they are not logins or handles. Put differently, a username is an anonymous way to initiate conversations on the chat platform without having to share phone numbers. The feature is opt-in, although Signal said it's also taking steps to hide by default users' phone numb
Bumblebee Malware Returns with New Tricks, Targeting U.S. Businesses

Bumblebee Malware Returns with New Tricks, Targeting U.S. Businesses

Feb 14, 2024 Malware / Cybercrime
The infamous malware loader and initial access broker known as  Bumblebee  has resurfaced after a four-month absence as part of a new phishing campaign observed in February 2024. Enterprise security firm Proofpoint said the activity targets organizations in the U.S. with voicemail-themed lures containing links to OneDrive URLs. "The URLs led to a Word file with names such as "ReleaseEvans#96.docm" (the digits before the file extension varied)," the company  said  in a Tuesday report. "The Word document spoofed the consumer electronics company Humane." Opening the document leverages VBA macros to launch a PowerShell command to download and execute another PowerShell script from a remote server that, in turn, retrieves and runs the Bumblebee loader. Bumblebee,  first spotted  in March 2022, is mainly designed to download and execute follow-on payloads such as ransomware. It has been put to use by multiple crimeware threat actors that previously observe

PikaBot Resurfaces with Streamlined Code and Deceptive Tactics

Feb 13, 2024 Cyber Threat / Malware
The threat actors behind the PikaBot malware have made significant changes to the malware in what has been described as a case of "devolution." "Although it appears to be in a new development cycle and testing phase, the developers have reduced the complexity of the code by removing advanced obfuscation techniques and changing the network communications," Zscaler ThreatLabz researcher Nikolaos Pantazopoulos  said . PikaBot,  first documented  by the cybersecurity firm in May 2023, is a malware loader and a backdoor that can execute commands and inject payloads from a command-and-control (C2) server as well as allow the attacker to control the infected host. It is also known to halt its execution should the system's language be Russian or Ukrainian, indicating that the operators are either based in Russia or Ukraine. In recent months, both PikaBot and another loader called DarkGate have emerged as  attractive replacements  for threat actors such as  Water C

Rhysida Ransomware Cracked, Free Decryption Tool Released

Feb 12, 2024 Vulnerability / Data Recovery
Cybersecurity researchers have uncovered an "implementation vulnerability" that has made it possible to reconstruct encryption keys and decrypt data locked by Rhysida ransomware. The findings were published last week by a group of researchers from Kookmin University and the Korea Internet and Security Agency (KISA). "Through a comprehensive analysis of Rhysida Ransomware, we identified an implementation vulnerability, enabling us to regenerate the encryption key used by the malware," the researchers  said . The development marks the first successful decryption of the ransomware strain, which first made its appearance in May 2023. A  recovery tool  is being distributed through KISA. The study is also the latest to achieve data decryption by exploiting implementation vulnerabilities in ransomware, after  Magniber v2 , Ragnar Locker,  Avaddon , and  Hive . Rhysida , which is known to share overlaps with another ransomware crew called Vice Society, leverages a ta
