By Waqas The Swing VPN app is available on Android and iOS devices; however, only the Android version has been identified as a DDoS botnet by the researcher. This is a post from HackRead.com Read the original post: Researcher Identifies Popular Swing VPN Android App as DDoS Botnet

A new malware called Condi has been observed exploiting a security vulnerability in TP-Link Archer AX21 (AX1800) Wi-Fi routers to rope the devices into a distributed denial-of-service (DDoS) botnet. Fortinet FortiGuard Labs said the campaign has ramped up since the end of May 2023. Condi is the work of a threat actor who goes by the online alias zxcr9999 on Telegram and runs a Telegram channel

### Summary The `SniHandler` can allocate up to 16MB of heap for each channel during the TLS handshake. When the handler or the channel does not have an idle timeout, it can be used to make a TCP server using the `SniHandler` to allocate 16MB of heap. ### Details The `SniHandler` class is a handler that waits for the TLS handshake to configure a `SslHandler` according to the indicated server name by the `ClientHello` record. For this matter it allocates a `ByteBuf` using the value defined in the `ClientHello` record. Normally the value of the packet should be smaller than the handshake packet but there are not checks done here and the way the code is written, it is possible to craft a packet that makes the `SslClientHelloHandler` 1/ allocate a 16MB `ByteBuf` 2/ not fail `decode` method `in` buffer 3/ get out of the loop without an exception The combination of this without the use of a timeout makes easy to connect to a TCP server and allocate 16MB of heap memory per connection. ...

By Waqas Microsoft has acknowledged that the crippling service outages in early June 2023 were caused by a DDoS attack apparently carried out by "Anonymous Sudan." This is a post from HackRead.com Read the original post: Microsoft Discloses DDoS Attack Impact with Limited Details

Microsoft on Friday attributed a string of service outages aimed at Azure, Outlook, and OneDrive earlier this month to an uncategorized cluster it tracks under the name 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," the tech giant said in a post on Friday. Storm-#### (

Cybersecurity researchers have discovered previously undocumented payloads associated with a Romanian threat actor named Diicot, revealing its potential for launching distributed denial-of-service (DDoS) attacks. "The Diicot name is significant, as it's also the name of the Romanian organized crime and anti-terrorism policing unit," Cado Security said in a technical report. "In addition,

The DDoS collective claims to be teaming up with ReVIL and Anonymous Sudan for destructive financial attacks in retaliation for US aid in Ukraine, but the partnerships (and danger) are far from verified.

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.
