New Mystic Stealer Malware Targets 40 Web Browsers and 70 Browser Extensions

New Mystic Stealer Malware Targets 40 Web Browsers and 70 Browser Extensions

Jun 19, 2023 Data Safety / Browser Security
A new information-stealing malware called  Mystic Stealer  has been found to steal data from about 40 different web browsers and over 70 web browser extensions. First advertised on April 25, 2023, for $150 per month, the malware also targets cryptocurrency wallets, Steam, and Telegram, and employs extensive mechanisms to resist analysis. "The code is heavily obfuscated making use of polymorphic string obfuscation, hash-based import resolution, and runtime calculation of constants,"  InQuest  and  Zscaler  researchers said in an analysis published last week. Mystic Stealer, like many other crimeware solutions that are offered for sale, focuses on pilfering data and is implemented in the C programming language. The control panel has been developed using Python. Updates to the malware in May 2023 incorporate a loader component that allows it to retrieve and execute next-stage payloads fetched from a command-and-control (C2) server, making it a more formid...
Researchers Discover New Sophisticated Toolkit Targeting Apple macOS Systems

Researchers Discover New Sophisticated Toolkit Targeting Apple macOS Systems

Jun 19, 2023 Endpoint Security / Hacking
Cybersecurity researchers have uncovered a set of malicious artifacts that they say is part of a sophisticated toolkit targeting Apple macOS systems. "As of now, these samples are still largely undetected and very little information is available about any of them," Bitdefender researchers Andrei Lapusneanu and Bogdan Botezatu  said  in a preliminary report published on Friday. The Romanian firm's analysis is based on an examination of four samples that were uploaded to VirusTotal by an unnamed victim. The earliest sample dates back to April 18, 2023. Two of the three malicious programs are said to be generic Python-based backdoors that are designed to target Windows, Linux, and macOS systems. The payloads have been collectively dubbed  JokerSpy . The first constituent is shared.dat, which, once launched, runs an operating system check (0 for Windows, 1 for macOS, and 2 for Linux) and establishes contact with a remote server to fetch additional instructions for execut...

Introducing AI-guided Remediation for IaC Security / KICS

Jun 19, 2023 DevSecOps / AppSec
While the use of Infrastructure as Code (IaC) has gained significant popularity as organizations embrace cloud computing and DevOps practices, the speed and flexibility that IaC provides can also introduce the potential for misconfigurations and security vulnerabilities.  IaC allows organizations to define and manage their infrastructure using machine-readable configuration files, which are typically version-controlled and treated as code. IaC misconfigurations are mistakes, or oversights, in the configuration of infrastructure resources and environments that happen when using IaC tools and frameworks. Discover the power of a comprehensive AppSec platform.

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...
State-Backed Hackers Employ Advanced Methods to Target Middle Eastern and African Governments

State-Backed Hackers Employ Advanced Methods to Target Middle Eastern and African Governments

Jun 19, 2023 Cyber Attack / Hacking
Governmental entities in the Middle East and Africa have been at the receiving end of sustained cyber-espionage attacks that leverage never-before-seen and rare credential theft and Exchange email exfiltration techniques. "The main goal of the attacks was to obtain highly confidential and sensitive information, specifically related to politicians, military activities, and ministries of foreign affairs," Lior Rochberger, senior threat researcher at Palo Alto Networks,  said  in a technical deep dive published last week. The company's Cortex Threat Research team is  tracking  the activity under the temporary name  CL-STA-0043  (where CL stands for cluster and STA stands for state-backed motivation), describing it as a "true advanced persistent threat." The infection chain is triggered by the exploitation of vulnerable on-premises Internet Information Services ( IIS ) and Microsoft Exchange servers to infiltrate target networks. Palo Alto Networks said i...
Microsoft Blames Massive DDoS Attack for Azure, Outlook, and OneDrive Disruptions

Microsoft Blames Massive DDoS Attack for Azure, Outlook, and OneDrive Disruptions

Jun 19, 2023 Network and Cloud Security
Microsoft on Friday attributed a string of service outages aimed at Azure, Outlook, and OneDrive earlier this month to an uncategorized cluster it tracks under the name  Storm-1359 . "These attacks likely rely on access to multiple virtual private servers (VPS) in conjunction with rented cloud infrastructure, open proxies, and DDoS tools," the tech giant  said  in a post on Friday. Storm-#### (previously DEV-####) is a temporary designation the Windows maker assigns to unknown, emerging, or developing groups whose identity or affiliation hasn't been definitively established yet. While there is no evidence that any customer data was accessed or compromised, the company noted the attacks "temporarily impacted availability" of some services. Redmond said it further observed the threat actor launching  layer 7 DDoS attacks  from multiple cloud services and open proxy infrastructures. This includes HTTP(S) flood attacks, which bombard the target services with a ...
 From Cryptojacking to DDoS Attacks: Diicot Expands Tactics with Cayosin Botnet

From Cryptojacking to DDoS Attacks: Diicot Expands Tactics with Cayosin Botnet

Jun 17, 2023 Cryptojacking / Network Security
Cybersecurity researchers have discovered previously undocumented payloads associated with a Romanian threat actor named  Diicot , revealing its potential for launching distributed denial-of-service (DDoS) attacks. "The Diicot name is significant, as it's also the name of the  Romanian organized crime and anti-terrorism policing unit ," Cado Security  said  in a technical report. "In addition, artifacts from the group's campaigns contain messaging and imagery related to this organization." Diicot (née Mexals) was  first documented  by Bitdefender in July 2021, uncovering the actor's use of a Go-based SSH brute-forcer tool called Diicot Brute to breach Linux hosts as part of a cryptojacking campaign. Then earlier this April, Akamai  disclosed  what it described as a "resurgence" of the 2021 activity that's believed to have started around October 2022, netting the actor about $10,000 in illicit profits. "The attackers use a long ch...

ChamelDoH: New Linux Backdoor Utilizing DNS-over-HTTPS Tunneling for Covert CnC

Jun 16, 2023 Endpoint Security / Network Security
The threat actor known as  ChamelGang  has been observed using a previously undocumented implant to backdoor Linux systems, marking a new expansion of the threat actor's capabilities. The malware, dubbed  ChamelDoH  by Stairwell, is a C++-based tool for communicating via DNS-over-HTTPS ( DoH ) tunneling. ChamelGang was  first outed  by Russian cybersecurity firm Positive Technologies in September 2021, detailing its attacks on fuel, energy, and aviation production industries in Russia, the U.S., India, Nepal, Taiwan, and Japan. Attack chains mounted by the actor have leveraged vulnerabilities in Microsoft Exchange servers and Red Hat JBoss Enterprise Application to gain initial access and carry out data theft attacks using a passive backdoor called DoorMe. "This is a native  IIS module  that is registered as a filter through which HTTP requests and responses are processed," Positive Technologies said at the time. "Its principle of operation ...

20-Year-Old Russian LockBit Ransomware Affiliate Arrested in Arizona

Jun 16, 2023 Ransomware / Cyber Crime
The U.S. Department of Justice (DoJ) on Thursday unveiled charges against a Russian national for his alleged involvement in deploying LockBit ransomware to targets in the U.S., Asia, Europe, and Africa. Ruslan Magomedovich Astamirov, 20, of Chechen Republic has been accused of perpetrating at least five attacks between August 2020 and March 2023. He was arrested in the state of Arizona last month. "Astamirov allegedly participated in a conspiracy with other members of the LockBit ransomware campaign to commit wire fraud and to intentionally damage protected computers and make ransom demands through the use and deployment of ransomware," the DoJ  said . Astamirov, as part of his LockBit-related activities, managed various email addresses, IP addresses, and other online accounts to deploy the ransomware and communicate with the victims. Law enforcement agencies said they were able to trace a chunk of an unnamed victim's ransom payment to a virtual currency address operated by A...
