WordPress sites are being hacked to display fake Cloudflare DDoS protection pages to distributing NetSupport RAT and the RaccoonStealer password-stealing Trojan.

“A worrying feature in pip/PyPI allows code to automatically run when developers are merely downloading a package,” Checkmarx researcher Yehuda Gelb said in a technical report published this week.

Always monitor the 

One of the ways by which packages can be installed for Python is by executing the “pip install” command, which, in turn, invokes a file called “setup.py” that comes bundled along with the module.

“setup.py,” as the name implies, is a setup script that’s used to specify metadata associated with the package, including its dependencies.

Always monitor the dependencies for PIP

“pip download does the same resolution and downloading as pip install, but instead of installing the dependencies, it collects the downloaded distributions into the directory provided (defaulting to the current directory),” the documentation reads.

In other words, the command can be used to download a Python package without having to install it on the system. But as it turns out, executing the download command also runs the aforementioned “setup.py” script, resulting in the execution of malicious code contained within it.

Prynt Stealer new data extractor malware

 

Telegram 'hacker' threatens 'bombshell' crypto revelations

Researchers discovered a private Telegram channel-based backdoor in the information stealing malware, dubbed Prynt Stealer, which its developer added with the intention of secretly stealing a copy of victims’ exfiltrated data when used by other cybercriminals.

The cybersecurity firm analysis of Prynt Stealer shows that its codebase is derived from two other open source malware families, AsyncRAT and StormKitty, with new additions incorporated to include a backdoor Telegram channel to collect the information stolen by other actors to the malware’s author.

Prynt Stealer

“The Prynt Stealer author went a step further and added a backdoor to steal from their customers by hardcoding a Telegram token and chat ID into the malware. As the saying goes, there is no honour among thieves.”

Samsung reveals US customers exposed in the latest breach 

South Korean Samsung on September 2 has released a report on a recent cybersecurity incident that resulted in the unauthorized access of some customer information, the second time this year it has reported such a breach.

“In late July 2022, an unauthorized third-party acquired information from some of Samsung’s U.S. systems,” the company disclosed in a notice. “On or around August 4, 2022, we determined through our ongoing investigation that the personal information of certain customers was affected.”

The announcement comes less than six months after Samsung confirmed a similar incident. In March 2022, it revealed that internal data, including the source code related to its Galaxy smartphones, was leaked in the aftermath of an attack staged by the LAPSUS$ extortion gang.
