Summary Summary Beginning in early June 2023, Microsoft identified surges in traffic against some services that temporarily impacted availability. Microsoft promptly opened an investigation and subsequently began tracking ongoing DDoS activity by the threat actor that Microsoft tracks as Storm-1359. These attacks likely rely on access to multiple virtual private servers (VPS) in conjunction with rented cloud infrastructure, open proxies, and DDoS tools.

snappy-java is a fast compressor/decompressor for Java. Due to unchecked multiplications, an integer overflow may occur in versions prior to 1.1.10.1, causing an unrecoverable fatal error. The function `compress(char[] input)` in the file `Snappy.java` receives an array of characters and compresses it. It does so by multiplying the length by 2 and passing it to the rawCompress` function. Since the length is not tested, the multiplication by two can cause an integer overflow and become negative. The rawCompress function then uses the received length and passes it to the natively compiled maxCompressedLength function, using the returned value to allocate a byte array. Since the maxCompressedLength function treats the length as an unsigned integer, it doesn’t care that it is negative, and it returns a valid value, which is casted to a signed integer by the Java engine. If the result is negative, a `java.lang.NegativeArraySizeException` exception will be raised while trying to allocate ...

The U.S. government agency in charge of improving the nation's cybersecurity posture is ordering all federal civilian agencies to take new measures to restrict access to Internet-exposed networking equipment. The directive comes amid a surge in attacks targeting previously unknown vulnerabilities in widely used security and networking appliances.

A suspected China-nexus threat actor dubbed UNC4841 has been linked to the exploitation of a recently patched zero-day flaw in Barracuda Email Security Gateway (ESG) appliances since October 2022. "UNC4841 is an espionage actor behind this wide-ranging campaign in support of the People's Republic of China," Google-owned Mandiant said in a new report published today, describing the group as "

**The following mitigating factors might be helpful in your situation:** Exploitation of the security issues in the drivers requires multiple steps, the primary of which is the ability of an attacker to direct a client (that they want to compromise) to connect to their malicious server. If your environment only connects to known, trusted servers and there is no ability to direct existing connection configurations to the wrong server (e.g., you use TLS encryption with certificate validation), these issues can not be exploited.
