Cybersecurity researchers have called attention to a massive phishing campaign targeting the hospitality industry that lures hotel managers to ClickFix-style pages and harvest their credentials by deploying malware like PureRAT. "The attacker's modus operandi involved using a compromised email account to send malicious messages to multiple hotel establishments," Sekoia said. "This campaign

Microsoft has disclosed details of a novel side-channel attack targeting remote language models that could enable a passive adversary with capabilities to observe network traffic to glean details about model conversation topics despite encryption protections under certain circumstances. This leakage of data exchanged between humans and streaming-mode language models could pose serious risks to

### Summary pdfminer.six will execute arbitrary code from a malicious pickle file if provided with a malicious PDF file. The `CMapDB._load_data()` function in pdfminer.six uses `pickle.loads()` to deserialize pickle files. These pickle files are supposed to be part of the pdfminer.six distribution stored in the `cmap/` directory, but a malicious PDF can specify an alternative directory and filename as long as the filename ends in `.pickle.gz`. A malicious, zipped pickle file can then contain code which will automatically execute when the PDF is processed. ### Details ```python # Vulnerable code in pdfminer/cmapdb.py:233-246 def _load_data(cls, name: str) -> Any: name = name.replace("\0", "") # Insufficient sanitization filename = "%s.pickle.gz" % name # ... path construction ... path = os.path.join(directory, filename) # If filename is an absolte path, directory is ignored # ... return type(str(name), (), pickle.loads(gzfile.read())) # Unsafe deserializatio...

A China-linked threat actor has been attributed to a cyber attack targeting an U.S. non-profit organization with an aim to establish long-term persistence, as part of broader activity aimed at U.S. entities that are linked to or involved in policy issues. The organization, according to a report from Broadcom's Symantec and Carbon Black teams, is "active in attempting to influence U.S. government

Cybersecurity researchers have flagged a malicious Visual Studio Code (VS Code) extension with basic ransomware capabilities that appears to be created with the help of artificial intelligence – in other words, vibe-coded. Secure Annex researcher John Tuckner, who flagged the extension "susvsex," said it does not attempt to hide its malicious functionality. The extension was uploaded on

This edition, Hazel explores the origins of Guy Fawkes Day and how heeding an anonymous warning prevented an assassination.

Malwarebytes for Windows introduces powerful privacy controls, so you get to decide how Microsoft uses your data—all from one simple screen.

A misconfiguration in the sudoers file permits passwordless execution of specific Bash shell scripts via sudo, exposing a critical privilege escalation vulnerability. When such scripts are writable by a web-facing user (www-data) or accessible through a command injection vector, an attacker can overwrite or replace them with malicious payloads. Upon execution with sudo, these scripts run with elevated privileges, allowing the attacker to gain full root access remotely.

The application stores user passwords in the database using the MD5 hashing algorithm, which is considered cryptographically insecure due to its vulnerability to collision and brute-force attacks. MD5 lacks modern protections such as salting and computational hardness, making it trivial for attackers to crack password hashes using precomputed rainbow tables or GPU-accelerated dictionary attacks.
