qkG file-encoding ransomware
Several users have encountered a few samples of file-coding ransomware variant written entirely in VBA macros called qkG. This stands out as the first ransomware to scramble one file (and file type), and one of the few file-encrypting malware written entirely in Visual Basic for Applications (VBA) macros.

Terdot trojan
The banking trojan -- Terdot -- which appeared on the scene as late as 2016, has since grown into a full-fledged hacking tool. It also works as a backdoor and info stealer. One of the features of Terdot is its use of legitimate services in order to read HTTPS traffic.

Top Vulnerabilities Reported in the Last 24 Hours

HP enterprise printer vulnerability
Security researchers have detected a few potentially serious flaws that include path traversal flaw and code execution flaw. It allows an attacker to access the content of any print job, including PIN-protected jobs.

Excel vulnerability
A vulnerability is found in the xls_mergedCells function of libxls 1.4. It is a C library supported on Windows, Mac, and Linux which can read Microsoft Excel file format (XLS) files. An attacker can send malicious XLS file through spam email to trigger this vulnerability.
