With the "Follina" / CVE-2022-30190 0day still hot, i.e., still waiting for an official fix while apparently already getting exploited by nation-backed attackers, another related unfixed vulnerability in Microsoft's Diagnostic Tool (MSDT) bubbled to the surface. In January 2020, security researcher Imre Rad published an article titled "The trouble with Microsoft’s Troubleshooters," describing a method for having a malicious executable file being saved to user's Startup folder, where it would subsequently get executed upon user's next login. What the user has to do for this to happen is open a "diagcab" file...

XVigil discovered a financially motivated threat actor group, dubbed Eternity group, actively operating on the internet, selling worms, stealers, DDoS tools, and ransomware builders.

At Grapl we believe that in order to build the best defensive system we need to deeply understand attacker behaviors. As part of that goal we're investing in offensive security research. Keep up with our blog for new research on high risk vulnerabilities, exploitation, and advanced threat tactics.

In July 2021, CPR released a series of three publications covering different aspects of how the Formbook and XLoader malware families function. We described how XLoader emerged in the Darknet community to fill the empty niche after Formbook sales were abruptly stopped by its author. We did a deep technical analysis followed by a description of XLoader for macOS along with common points and differences in how both malware families conceal the heart of the whole operation, the Command-and-Control (C&C) infrastructure. However, the world does not stand still, and this applies to the malware cyber-world as well.

Trend Micro Research detected “Cheerscrypt”, a new Linux-based ransomware variant that compromises ESXi servers. We discuss our initial findings in this report.

User tracking technologies are ubiquitous on the web. In recent times web browsers try to fight abuses. This led to an arms race where new tracking and anti-tracking measures are being developed. The use of one of such evasion techniques, the CNAME cloaking technique is recently quickly gaining popularity. Our evidence indicates that the use of the CNAME scheme threatens web security and privacy systematically and in general

A new study by Juniper Research has found operators will generate $27 billion from the termination of SMS messages related to multi-factor authentication in 2022; an increase from $25 billion in 2021. The research predicts this 5% growth will be driven by increased pressure on digital service providers to offer secure authentication that reduces risk of data breaches and protects user identity. Multi-factor authentication combines multiple credentials to verify a user or transaction. This includes sending an SMS that contains a one‑time password or code to a user’s unique phone number.

Tracking, marketing, and analytics firms have been exfiltrating the email addresses of internet users from web forms prior to submission and without user consent, according to security researchers.

The JFrog Security Research team identified and quickly disclosed new npm malicious packages aimed at compromising leading industrial organizations

We discovered a now-patched vulnerability in macOS SUHelper, designated as CVE-2022-22639. If exploited, the vulnerability could allow malicious actors to gain root privilege escalation.

The activity we have observed has been attributed to a threat group that Microsoft tracks as DEV-0537, also known as LAPSUS$. DEV-0537 is known for using a pure extortion and destruction model without deploying ransomware payloads.

A search online lead me to a discovery I didn’t think was possible nowadays. I realized almost immediately that critical security issues were probably involved. I found that out of the many tens of thousands of gas stations the company claimed to have installed their product in, 1,000 are remotely hackable.

We recently came across a stealer, called Raccoon Stealer, a name given to it by its author. Raccoon Stealer uses the Telegram infrastructure to store and update actual C&C addresses.  Raccoon Stealer is a password stealer capable of stealing not just passwords, but various types of data, including: Cookies, saved logins and forms data from […]

Cisco Talos has observed new cyber attacks targeting Turkey and other Asian countries we believe with high confidence are from groups operating under the MuddyWater umbrella of APT groups. U.S. Cyber Command recently connected MuddyWater to Iran's Ministry of Intelligence and Security (MOIS).

Geneva is a genetic algorithm that automatically learns how to evade nation state censors.

Last seen in August 2021, Zloader, a banking malware designed to steal user credentials and private information, is back with a simple yet sophisticated infection chain. Previous Zloader campaigns, which were seen in 2020, used malicious documents, adult sites and Google ads to infect systems. Evidence of the new campaign was first seen around early November 2021. The techniques incorporated in the infection chain include the use of legitimate remote management software (RMM) to gain initial access to the target machine.
