SafeBreach customers can select and run these attacks and more from the SafeBreach Hacker’s Playbook™ to ensure coverage against these advanced threats.

With the worldwide popularity of Android and its open-source software, hackers have an increased incentive and opportunity to orchestrate attacks. A Google search for “Android malware” brings up headlines like these, all from the past few days or weeks: SecurityScorecard recently analyzed a specific threat known as the AhMyth RAT (remote access trojan), which made headlines for infiltrating a popular screen recording app on the Google Play Store.

Security teams use tools like Microsoft Sentinel to aggregate their security events, alert on threat detection, and most importantly, orchestrate threat responses through a variety of automated playbooks. By providing both Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) functionality, Sentinel enables teams to respond to threats quickly and efficiently.

Malicious npm packages and their dangers have been a frequent topic of discussion — whether it’s hundreds of command-and-control Cobalt Strike malware packages, typosquatting, or general malware published to the npm registry (including PyPI and others). To help developers and maintainers defend against these security risks, Snyk published a guide to npm security best practices.

Ransomware is still present and growing across the threat landscape, to the extent that some organizations now include the cost of a ransomware attack in their annual budgets. Data from our Internet Security Report - Q4 2022 reveals that ransomware detections on endpoints rose by an alarming 627% in 2022 compared to the previous year. While ransomware does not discriminate by industry type, the report clearly shows the manufacturing sector was the most affected during 2022.

GraphQL has become a popular choice for building APIs in recent years. In projects using Typescript and Apollo Client, such as Rubrik’s, it is very helpful to map GraphQL schema to types and interfaces and one of the most popular tools for generating these types and interfaces based on a GraphQL schema is Apollo Codegen.

In recent months, a cybercrime group known as Blacktail has begun to make headlines as they continue to target organizations around the globe. The group was first spotted by the Unit 42 Team at Palo Alto Networks earlier this year. Since February, the group has launched multiple attacks based on their latest ransomware campaign labeled Buhti.

Unstructured data is a prime target for ransomware attacks, making it crucial for organizations to protect and manage it effectively. Currently, it is estimated that 80-90% of all data generated falls into the unstructured category, consisting of files and objects. Organizations rely on unstructured data to store sensitive information, intellectual property, and other invaluable corporate assets.

The NSA has published a guide about how to mitigate against attacks involving the BlackLotus bootkit malware, amid fears that system administrators may not be adequately protected against the threat. The BlackLotus UEFI bootkit made a name for itself in October 2022, when it was seen being sold on cybercrime underground forums for $5,000.

Kroll has analyzed incidents throughout Q1 2023 where drive-by compromise was the initial infection vector for GOOTLOADER malware. It is likely that the threat actors are utilizing SEO to drive individuals to either their own malicious website or to infected WordPress sites. These sites are then used to host documents that would be attractive to employees within the legal and professional services sectors.

Despite the security controls that OpenAI has imposed on ChatGPT to try to make it a secure space capable of assisting users in a variety of tasks, cybercriminals have managed to exploit this technology for malicious purposes. Recent research has shown that this generative artificial intelligence is capable of creating a new branch of polymorphic malware with relative ease. The main risk lies in ChatGPT's versatility, which allows it to create code that could easily be used for malware.

Classifying new and unknown (zero-day) malware has always been a challenge in the security industry as new variants are discovered in the wild at an overwhelming rate.

On June 14th, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC) along with its international cybersecurity partners released an advisory calling out the various indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) being leveraged by the LockBit ransomware operation over the past 3 years.

Cybercrime has become a dominant concern for many businesses, as well as individuals. Cybercriminals will target any business, and any individual if they can realize a profit from their minimal efforts. One of the ways that criminals achieve their goals is through the use of malware that garners a fast profit, such as ransomware. More enterprising criminals will use more persistent malware, which enables them to return to the target for further victimization.

In a recent development, Russian hackers have declared their intention to launch cyberattacks on the European financial system within the next 48 hours. The announcement was made late on Wednesday, June 14 and came through a video threat posted on the Mash Telegram channel, a very popular channel for Russian news. This operation appears to be a collaborative effort between the hacking groups KillNet, REvil, and Anonymous Sudan.

To identify malicious packages and protect yourself against them, you need to know what to look for. Here’s a simple guide.
