Redisson is a Java Redis client that uses the Netty framework. Prior to version 3.22.0, some of the messages received from the Redis server contain Java objects that the client deserializes without further validation. Attackers that manage to trick clients into communicating with a malicious server can include especially crafted objects in its responses that, once deserialized by the client, force it to execute arbitrary code. This can be abused to take control of the machine the client is running in. Version 3.22.0 contains a patch for this issue. Some post-fix advice is available. Do NOT use `Kryo5Codec` as deserialization codec, as it is still vulnerable to arbitrary object deserialization due to the `setRegistrationRequired(false)` call. On the contrary, `KryoCodec` is safe to use. The fix applied to `SerializationCodec` only consists of adding an optional allowlist of class names, even though making this behavior the default is recommended. When instantiating `SerializationCodec`...

XXL-RPC is a high performance, distributed RPC framework. With it, a TCP server can be set up using the Netty framework and the Hessian serialization mechanism. When such a configuration is used, attackers may be able to connect to the server and provide malicious serialized objects that, once deserialized, force it to execute arbitrary code. This can be abused to take control of the machine the server is running by way of remote code execution. This issue has not been fixed.

A ransomware group called Dark Angels made headlines this past week when it was revealed the crime group recently received a record $75 million data ransom payment from a Fortune 50 company. Security experts say the Dark Angels have been around since 2021, but the group doesn't get much press because they work alone and maintain a low profile, picking one target at a time and favoring mass data theft over disrupting the victim's operations.

In the cloud, patches disseminate automatically. On your computer, you get notified. IoT devices, meanwhile, can escape attention for years on end.

The APT used DNS poisoning to install the Macma backdoor on targeted networks and then deliver malware to steal data via post-exploitation activity.

Debian Linux Security Advisory 5737-1 - If LibreOffice failed to validate a signed macro, it displayed a warning but still allowed execution of the script after printing a warning. Going forward in high macro security mode such macros are now disabled.

Ubuntu Security Notice 6895-4 - It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service.

Cybersecurity startup LeakSignal, a finalist in this year's Black Hat USA Startup Spotlight competition, helps organizations see where data is leaking within their environments.

Organizations in Kazakhstan are the target of a threat activity cluster dubbed Bloody Wolf that delivers a commodity malware called STRRAT (aka Strigoi Master). "The program selling for as little as $80 on underground resources allows the adversaries to take control of corporate computers and hijack restricted data," cybersecurity vendor BI.ZONE said in a new analysis. The cyber attacks employ

The scheme, from the group also known as APT28, involves targeting Eastern European diplomats in need of personal transportation and tempting them with a purported good deal on a Audi Q7 Quattro SUV.
