The FBI is warning US consumers that cybercriminals are placing ads in search engine results that impersonate well-known brands, in an attempt to spread ransomware and steal financial information. In a public service announcement issued this week, the FBI describes how cybercriminals are purchasing ads that show up at the very top of search engine results, often purporting to link to a legitimate company's website.
After Microsoft announced this year that macros from the Internet will be blocked by default in Office, many threat actors have switched to different file types such as Windows Shortcut (LNK), ISO or ZIP files, to distribute their malware. Nevertheless, Office documents are still actively leveraged in many campaigns and pose a large risk to organizations, especially with threat actors continuously finding new ways to avoid detection.
CrowdStrike analyzes malware to augment the behavior and machine learning-based detection and protection capabilities built into the CrowdStrike Falcon® platform to deliver automated, world-class protection to customers. GuLoader has been known to employ a significant number of anti-analysis techniques, making detection and protection challenging for other security solutions.
How hackers are using SVG files to smuggle QBot malware onto Windows systems, a new batch of ransomware families leading attacks on Windows systems, and this year’s spike in command-and-control servers.
Ransomware is one of the most dangerous cyber attacks to businesses and consumers. This type of malware holds files and data hostage until a ransom is paid. Ransomware incidents can result in data loss, financial losses, and even ransomware payments. In order to protect your business from ransomware-based data breaches, it is important to understand ransomware statistics, ransomware trends, and the best practices for ransomware prevention.
If I asked you what the common ways to exploit a cloud app for malicious purposes are, I bet your answer would probably be either to use it to distribute malicious content (such as malware or phishing pages), or to host the command and control (C2) infrastructure. In reality another frequent technique is the dead drop resolver, where a legitimate service is abused by threat actors to host the information related to the C2 infrastructure rather than the C2 infrastructure itself.
The JFrog Security Research team continuously monitors popular open-source software (OSS) repositories with our automated tooling, and reports any vulnerabilities or malicious packages discovered to repository maintainers and the wider community.
Kroll has observed threat actors abusing Google Ads to deploy malware masquerading as legitimate downloads or software that has been “cracked” or modified to remove or disable features such as copy protection or adware. As part of our analysis of this trend and threat, we have identified specifically that VIDAR malware, an information-stealing trojan, is using Google Ads to advertise spoofed domains and redirect users to fraudulent sites or malware downloads.
