A new targeted phishing campaign includes the novel obfuscation technique of using Morse code to hide malicious URLs in an email attachment.
Samuel Morse and Alfred Vail invented morse code as a way of transmitting messages across telegraph wire. When using Morse code, each letter and number is encoded as a series of dots (short sound) and dashes (long sound).
Starting last week, a threat actor began utilizing Morse code to hide malicious URLs in their phishing form to bypass secure mail gateways and mail filters.
BleepingComputer could not find any references to Morse code being used in phishing attacks in the past, making this a novel obfuscation technique

A recently discovered heap-based buffer overflow vulnerability in Linux SUDO also impacts the latest version of Apple macOS Big Sur, with no patch available yet.
Last week, BleepingComputer had reported on
, a flaw in SUDO which lets local users gain root privileges.
Sudo is a Unix program that enables system admins to provide limited root privileges to normal users listed in the
sudoers file, while at the same time keeping a log of their activity.
This helps limits the rights of standard users on an operating system by preventing them from executing high-risk commands and programs which may compromise the system s security.

The QNAP TS-253D-4G ($369) is a two-bay NAS designed for business and home users who require a network attached storage device that brings high-speed connectivity and expandability. Powered by a robust 2GHz Intel Celeron J4125 quad-core processor, the TS-253D turned in solid scores in our file transfer performance tests and offers a nice selection of apps. That said, our Editors’ Choice winner for two-bay NAS devices, the Asustor AS6602T, is a bit faster and offers a more extensive app catalog for just $30 more.
Plenty of Ports
The TS-253D-4G uses the same basic chassis as the TS-251B-4G we reviewed in 2019, but this time around it sports a black and gray finish rather than a white and silver one. It’s a two-bay NAS that measures 6.6 by 4.1 by 8.9 inches (HWD) and can accommodate 2.5 and 3.5 inch drives. It supports single JBOD, RAID 0, and RAID 1, and supports a total capacity of 32TB using two 16TB drives. Larger storage capacities can be ach

New research released today provides greater insight into the Emotet module created by law enforcement that will uninstall the malware from infected devices in April.
On January 27th, Europol announced that a joint operation between law enforcement agencies from Netherlands, Germany, the United States, the United Kingdom, France, Lithuania, Canada, and Ukraine took control of the Emotet botnet s servers and disrupted the malware s operation.
After the takedown, researchers noticed that the Emotet botnet began to push down a module to infected devices that would uninstall the malware on April 25th, 2021, at 12:00 and later.
