Threat actors are using the social engineering technique and a legitimate Microsoft tool to deploy the DCRat remote access Trojan against targets in the hospitality sector.

Another well-crafted phishing campaign uses Google Cloud Integration Application infrastructure to bypass email filters.

Phishing in 2026 is harder to detect and verify. Learn how CISOs can speed up investigations, reduce noise, and respond with confidence.

Source: Securonix Cybersecurity researchers have disclosed details of a new campaign dubbed PHALT#BLYX that has leveraged ClickFix-style lures to display fixes for fake blue screen of death (BSoD) errors in attacks targeting the European hospitality sector. The end goal of the multi-stage campaign is to deliver a remote access trojan known as DCRat, according to cybersecurity company Securonix.

### Summary Reading multiple invalid cookies can lead to a logging storm. ### Impact If the ``cookies`` attribute is accessed in an application, then an attacker may be able to trigger a storm of warning-level logs using a specially crafted Cookie header. ---- Patch: https://github.com/aio-libs/aiohttp/commit/64629a0834f94e46d9881f4e99c41a137e1f3326

### Summary Handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. ### Impact If an application makes use of the `request.read()` method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time. ----- Patch: https://github.com/aio-libs/aiohttp/commit/dc3170b56904bdf814228fae70a5501a42a6c712 Patch: https://github.com/aio-libs/aiohttp/commit/4ed97a4e46eaf61bd0f05063245f613469700229

### Summary A request can be crafted in such a way that an aiohttp server's memory fills up uncontrollably during processing. ### Impact If an application includes a handler that uses the `Request.post()` method, an attacker may be able to freeze the server by exhausting the memory. ----- Patch: https://github.com/aio-libs/aiohttp/commit/b7dbd35375aedbcd712cbae8ad513d56d11cce60

### Summary When assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. ### Impact If optimisations are enabled (`-O` or `PYTHONOPTIMIZE=1`), and the application includes a handler that uses the `Request.post()` method, then an attacker may be able to execute a DoS attack with a specially crafted message. ------ Patch: https://github.com/aio-libs/aiohttp/commit/bc1319ec3cbff9438a758951a30907b072561259

### Summary Path normalization for static files prevents path traversal, but opens up the ability for an attacker to ascertain the existence of absolute path components. ### Impact If an application uses `web.static()` (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components. ------ Patch: https://github.com/aio-libs/aiohttp/commit/f2a86fd5ac0383000d1715afddfa704413f0711e
