Our researcher @IsMR0a from GReAT, has been testing public Wi-Fi in the field.
Open network, no encryption. What you send, others can see.
Her rule: no banking or logins on public Wi-Fi. Use a VPN.

Across all three cities, however, 45% of “secure” networks still expose WPS, an outdated and easily compromised protocol that can leave devices vulnerable to unauthorized access and WPS-based attacks. (4/5)

“Seeing is no longer believing.”
Advances in AI are enabling the creation of highly convincing synthetic identities — combining real and fabricated data to bypass verification systems and scale fraud operations.

The CPU-Z and HWMonitor incident is the sloppiest supply chain attack I've EVER seen. The payloads have been copy-pasted from a previous attack, with C2 server reuse. The final implant, STX RAT, wasn't even cleaned from detections with PUBLICLY available Yara rules!🤦[1/4]

Kaspersky GReAT has discovered that a fake Starlink Android app is being used to distribute BeatBanker, a multi-purpose mobile threat.
An earlier version of BeatBanker combined a miner and banker. Newer ones pair a miner with a RAT.
One unusual trick: it loops a nearly inaudible audio file to help stay active on the device.

It turned out there are many more payloads used in the Notepad attack! To stay undetected, its masterminds were COMPLETELY changing execution chains about every month.
Here are more IPs used in the attack:
45.76.155[.]202
45.32.144[.]255
Read below for many other IoCs! [1/8]

🚨 #RevengeHotels (aka TA558) has been targeting travelers since 2015, stealing credit card data through phishing campaigns that look like ordinary document-sharing requests.
This summer, our experts uncovered something new: the group is now deploying #VenomRAT, a highly sophisticated tool designed to maximize damage. Even more alarming, evidence suggests parts of their malicious code may be AI-generated.
