If the attacker is asking for a few hundred dollars, you may feel paying would be the prudent choice. For example, if critical systems are shut down and customers cannot make purchases, the losses could easily get into the thousands. A user may reason that they are losing more money than the attacker is asking for as time goes by. When a ransomware attack has taken hold, it can be tempting to pay the ransom. Therefore, if you have been a victim of a ransomware attack, it is important to assume each storage device has been infected and clean them before allowing any devices in your network to attach to them. This may happen immediately or at some point in the future. If that happens, any device that connects to the storage system may get infected. The ransomware can potentially find the storage device and then infect it. Storage devices connected to the network need to be immediately disconnected as well. However, if it has already begun by the time you realize the computer has been infected, cutting off Wi-Fi can prevent it from spreading further. Shutting it down can stop this kind of east-west spread before it begins. The Wi-Fi connection can be used as a conduit to spread the ransomware to other devices connected to the same Wi-Fi network. In addition to hardware cables, you should also turn off the Wi-Fi that serves the area infected with the ransomware. Unplugging the printer can prevent it from being used to spread the ransomware. For example, your device may be connected to a printer that is linked to the local-area network (LAN). This includes anything that connects the infected device to the network itself or devices on the network. You should also disconnect any network cables attached to the device. Shutting it down prevents it from being used by the malware to further spread the ransomware. You should first shut down the system that has been infected.

This can prevent east-west attacks, where the ransomware spreads from one device to another through their network connections. Isolating the ransomware is the first step you should take. However, the latest versions of ransomware require more comprehensive security solutions. Initially, protecting against ransomware with a secure backup and proactive restore process were often enough to get an organization off the hook. The latest ransomware threat class requires much more than just a secure backup and proactive restore process. Ransomware attacks have crippled entire organizations for hours, days, or longer. Other attackers even go so far as to contact the customers whose data they’ve stolen in an attempt to collect payment from them. In addition to holding systems for ransom, some cybercriminals steal data and threaten to release it if ransom is not paid. Other types of attackers aren’t and won’t restore operations after payment out of spite or, perhaps, for political or other reasons.Ĭurrently, many ransomware campaigns employ multiple measures and methods to elicit payment. Some cybercriminals are solely financially motivated and will indeed return systems to operation after payment. Some ransomware just encrypt files while others that destroy file systems.

Since "run-only" AppleScript come in a compiled state where the source code isn't human-readable, this made analysis harder for security researchers.Read more of this story at Slashdot.Ransomware has evolved and now there are various types.

As users installed the pirated software, the boobytrapped installers would download and run a run-only AppleScript, which would download and run a second run-only AppleScript, and then another final third run-only AppleScript. The primary reason was that security researchers weren't able to retrieve the malware's entire code at the time, which used nested run-only AppleScript files to retrieve its malicious code across different stages. But their reports only scratched the surface of what OSAMiner was capable of, SentinelOne macOS malware researcher Phil Stokes said yesterday. SentinelOne said that two Chinese security firms spotted and analyzed older versions of the OSAMiner in August and September 2018, respectively. But the cryptominer did not go entirely unnoticed.

Named OSAMiner, the malware has been distributed in the wild since at least 2015 disguised in pirated (cracked) games and software such as League of Legends and Microsoft Office for Mac, security firm SentinelOne said in a report published this week. An anonymous reader quotes a report from ZDNet: For more than five years, macOS users have been the targets of a sneaky malware operation that used a clever trick to avoid detection and hijacked the hardware resources of infected users to mine cryptocurrency behind their backs.
