Swedish supermarket chain Kop was still struggling to recover on Tuesday after closing about half of its 800 stores with farms closed and self-service cash registers. Schools and kindergartens in New Zealand were also affected, as were some government offices in Romania. Germany's cybersecurity watchdog, BSI, said on Tuesday it had notified three affected IT service providers in Germany.

A software agent has been signed ransom With a trusted Windows certificate that uses the registrar name "PB03 TRANSPORT LTD". By digitally signing their malware, attackers are able to crack down on many security alerts that would appear if they were installed. Cybereason said that the certificate appears to have been used exclusively by the REvil malware that installed the attack.
To add secrecy, the attackers used a technique called DLL Side-Loading, which inserts a fake malicious DLL. In the WinSxS list for Windows so that the operating system loads the scam instead of the legal file. Currently, Agent.exe releases an older version of "msmpeng.exe" that is vulnerable to DLL sideloading, which applies to Windows Defender.

This is the latest example on a supply chain attack where hackers infect a reputable product provider with the aim of endangering key customers who use it. Discovered in December, the SolarWinds solution was used to deliver malware updates to 18,000 organizations using the company's network management tools. About nine federal agencies and 100 private organizations received repeated infections.
Anyone who suspects that their network has been affected in any way should investigate immediately. Kaseya has released a tool that VSA customers can use to detect infections on their networks. The FBI and the Cybersecurity and Infrastructure Security Agency have issued joint recommendations to Kaseya clients, especially if they are vulnerable. p>
