A new speculative execution vulnerability is impacting Windows and Linux systems that use Intel processors. Dubbed ‘SWAPGS’, the vulnerability can allow attackers to secretly monitor and steal sensitive information from a targeted machine. It is reported that the vulnerability primarily affects Intel processors manufactured after 2012. 

The past 24 hours also the emergence of a new cryptojacking campaign that managed to infiltrate around half a million PCs to mine cryptocurrency and steal data. The campaign was carried out using an upgraded version of Smominru botnet. This botnet variant includes both cryptomining and data-stealing modules. 

New variants of Echobot botnet and Lokibot trojan were also observed in the past 24 hours. While the new version of Echobot exploits 59 RCE vulnerabilities to propagate into IoT devices, the new Lokibot variant uses steganography to conceal its source code.

Smominru botnet evolves
Smominru botnet has been updated to go far beyond cryptomining. It is now capable of stealing information from vulnerable targets. The botnet was used in a cyberespionage campaign that infiltrated nearly 500,000 systems worldwide. Smominru has been active since 2017 and is generally distributed using EternalBlue exploit kit. 

Warshipping attack technique
Security researchers have discovered a new ‘Warshipping’ attack technique that can allow attackers to disrupt the business operation and steal sensitive data. The attack can be executed using a warship device which is made up of a single-board computer (SBC). The technique can also be used to launch other active wireless attacks such as evil twin attacks.  

Echobot evolves
Threat actors have upgraded the infamous Echobot botnet to exploit 59 RCE vulnerabilities found in IoT devices. Some of these exploits are as old as 2010. Apart from exploits, the botnet variant also includes a high number of payloads to infect routers, cameras, smart home hubs, network-attached storage systems, servers, database management software, and Zeroshell distribution. 

Lokibot trojan evolves
Security researchers have discovered a new variant of Lokibot trojan that uses steganography to propagate into systems. The malware variant hides its source code inside .png files, found within archive files attached to phishing emails. The new strain of malware has been sent through phishing emails to at least 56 organizations.
