Magecart threat actor rolls out convincing modal forms
To ensnare new victims, criminals will often devise schemes that attempt to look as realistic as possible. Having said that, it is not every day that we see the fraudulent copy exceed the original piece. While following up on an ongoing Magecart credit card skimmer campaign, we were almost fooled by a payment form that looked so well done we thought it was real. The threat actor used original logos from the compromised store and customized a web element known as a modal to perfectly hijack the checkout page.

Smartphones With Popular Qualcomm Chip Secretly Share Private Information With US Chip-Maker
During our security research we found that smart phones with Qualcomm chip secretly send personal data to Qualcomm. This data is sent without user consent, unencrypted, and even when using a Google-free Android distribution. This is possible because the Qualcomm chipset itself sends the data, circumventing any potential Android operating system setting and protection mechanisms. Affected smart phones are Sony Xperia XA2 and likely the Fairphone and many more Android phones which use popular Qualcomm chips.
PSA: upgrade your LUKS key derivation function
Here's an article from a French anarchist describing how his (encrypted) laptop was seized after he was arrested, and material from the encrypted partition has since been entered as evidence against him. His encryption password was supposedly greater than 20 characters and included a mixture of cases, numbers, and punctuation, so in the absence of any sort of opsec failures this implies that even relatively complex passwords can now be brute forced, and we should be transitioning to even more secure passphrases. Or does it? Let's go into what LUKS is doing in the first place. The actual data is typically encrypted with AES, an extremely popular and well-tested encryption algorithm. AES has no known major weaknesses and is not considered to be practically brute-forceable - at least, assuming you have a random key. Unfortunately it's not really practical to ask a user to type in 128 bits of binary every time they want to unlock their drive, so another approach has to be taken.
