Notorious malware attacks like Mirai highlight this threat to managed and IoT-connected devices. Applications and protocols that transmit login credentials over your network without proper encryption pose a significant security threat. An attacker connected to your network can intercept these credentials ...
In many cases, these malicious LNK files can reveal valuable information about the attacker’s development environment. To help get this information, a quick analysis is possible by viewing the properties of the file. However, we are encountering cases where the command line argument is so...
API Resolution:This makes analysis cumbersome for an analyst by hiding API call sequences. Runtime Code Patching:This likely evades detection mechanisms that scan process memory to identify malicious strings and code. Cisco Talosnotesthat: “The use of multiple obfuscations signifies the attacker’s...
When a user clicks on the ad, code in the ad either redirects them to a malicious website or installs malware on their computer. In some cases, the malware embedded in an ad might execute automatically without any action from the user, a technique referred to as a “drive-by download....
by standard security software difficult. Rootkits can also create a persistent state of presence that makes it difficult or impossible to shut them down, even with a system reboot. A rootkit can provide an attacker with ongoing access or change security authorization privileges to facilitate access....
too. These replicate critical data to an off-site data storage service, typically in the cloud. For the short term, tertiary/auxiliary backups have 30 to 90 days of total retention. Use a daily schedule and avoid any continually open network ports or services that a ransomware attacker co...
"The Sharpshooter technique allows an attacker to use a script to execute a .NET binary directly from memory without ever needing to reside on the disk," explains Andrea Lelli of the Windows Defender Research team. "This technique provides a framework that can enable attackers to ea...
