Stories about computer security tend to go viral when they bridge the vast divide between geeks and luddites, and this week’s news about a hacker who tried to poison a Florida town’s water supply was understandably front-page material. But for security nerds who’ve been warning about this sort of thing for ages, the most surprising aspect of the incident seems to be that we learned about it at all.

Microsoft today rolled out updates to plug at least 56 security holes in its Windows operating systems and other software. One of the bugs is already being actively exploited, and six of them were publicized prior to today, potentially giving attackers a head start in figuring out how to exploit the flaws.

MalwareBytes is reporting a weird software credit card skimmer. It harvests credit card data stolen by another, different skimmer:

Even though spotting multiple card skimmer scripts on the same online shop is not unheard of, this one stood out due to its highly specialized nature.

“The threat actors devised a version of their script that is aware of sites already injected with a Magento 1 skimmer,” Malwarebytes’ Head of Threat Intelligence Jérôme Segura explains in a report shared in advance with Bleeping Computer.

“That second skimmer will simply harvest credit card details from the already existing fake form injected by the previous attackers.”…

Hackers are exploiting a zero-day in SonicWall:

In an email, an NCC Group spokeswoman wrote: “Our team has observed signs of an attempted exploitation of a vulnerabilitythat affects the SonicWall SMA 100 series devices. We are working closely with SonicWall to investigate this in more depth.”

In Monday’s update, SonicWall representatives said the company’s engineering team confirmed that the submission by NCC Group included a “critical zero-day” in the SMA 100 series 10.x code. SonicWall is tracking it as SNWLID-2021-0001. The SMA 100 series…

It seems to be the season of sophisticated supply-chain attacks.

This one is in the NoxPlayer Android emulator:

ESET says that based on evidence its researchers gathered, a threat actor compromised one of the company’s official API (api.bignox.com) and file-hosting servers (res06.bignox.com).

Using this access, hackers tampered with the download URL of NoxPlayer updates in the API server to deliver malware to NoxPlayer users.

Despite evidence implying that attackers had access to BigNox servers since at least September 2020, ESET said the threat actor didn’t target all of the company’s users but instead focused on specific machines, suggesting this was a highly-targeted attack looking to infect only a certain class of users…
