Excerpt: “Noting that binaries written in these languages can appear more complex, convoluted, and tedious when disassembled, the researchers said the pivot adds additional layers of obfuscation, simply by virtue of them being relatively new, leading to a scenario where older malware developed using traditional languages like C++ and C# are being actively retooled with droppers and loaders written in uncommon alternatives to evade detection by endpoint security systems.”

Excerpt: “The CEO says recovering the disk has helped authorities to advance their investigations into the heist, and meant the company felt able to disclose the theft. The cloudy company has since revisited its data transfer policies, and now ships disks in sealed cases equipped with GPS trackers. Obviously it has no desire to have to explain such an improbable security story – for any incident of any origin – ever again.”

Excerpt: “The Babuk ransomware gang’s new rebrand isn’t going so well. It seems the cybercriminal group has been a victim of a ransomware attack of its own. Babuk’s latest endeavor, a Dark Web ransomware forum called RAMP, was crippled by a spammer over the weekend who overloaded the site with same-sex pornographic GIFs, according to Recorded Future. The attacker told Babuk they wanted $5,000. Babuk told them to pound sand, refused to pay and deleted the original post. But even after wiping the forum several times, Recorded Future said the attacker was still able to bombard the forum with pornographic GIFs.”

Title: Report: Online Retail Fraud in the Criminal Underground

Date Published: July 27, 2021

Excerpt: “Online retail fraud is a persistent, multifaceted threat to businesses of all sizes and their customers and is likely to persist for the foreseeable future as consumers engage more with online retailers and shop more online versus at traditional “brick and mortar” stores. Also called e-commerce fraud, online retail fraud is the act of committing some form of fraud, such as a fraudulent transaction, on a web-based retail platform. Generally, cybercriminals will use stolen payment or account information to conduct these transactions. Some elements of online retail fraud also involve social engineering schemes that look to defraud a retail platform directly, as in the case with refunding scams against one’s customer service branch, or a third party, such as interception fraud or scams that target shipping companies.”
