A massive malicious email campaign that stems from the world's largest spam botnet Necurs is spreading a new strain of ransomware at the rate of over 2 million emails per hour and hitting computers across the globe. The popular malspam botnet Necrus which has previously found distributing Dridex banking trojan , Trickbot banking trojan , Locky ransomwar e, and Jaff ransomware , has now started spreading a new version of Scarab ransomware. According to F-Secure , Necurs botnet is the most prominent deliverer of spam emails with five to six million infected hosts online monthly and is responsible for the biggest single malware spam campaigns. Scarab ransomware is a relatively new ransomware family that was initially spotted by ID Ransomware creator Michael Gillespie in June this year.

Hit by Jaff Ransomware? Don't pay the Ransom. You can unlock your files for Free! Kaspersky Labs has released an updated version 1.21.2.1 of its free ransomware decryption tool, RakhniDecryptor, which can now also decrypt files locked by the Jaff ransomware . Security researchers at Kaspersky Labs have discovered a weakness in the Jaff ransomware code that makes it possible for victims to unlock their Jaff-infected files for free. First identified last month, Jaff is relatively new ransomware that's being distributed with the help of ' Necurs botnet ' that currently controls over 6 million infected computers worldwide. Necurs botnet is the same botnet – army of compromised internet connected devices – that was used to distribute Dridex Banking Trojan and Locky ransomware , which also infects users' machines, encrypt files and then demand a ransom before unlocking them. Jaff ransomware (Trojan-Ransom.Win32.Jaff) attack is primarily carried out by sending ...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...

A massive malicious email campaign that stems from the Necurs botnet is spreading a new ransomware at the rate of 5 million emails per hour and hitting computers across the globe. Dubbed "Jaff," the new file-encrypting ransomware is very similar to the infamous Locky ransomware in many ways, but it is demanding 1.79 Bitcoins (approx $3,150), which much higher than Locky, to unlock the encrypted files on an infected computer. According to security researchers at Forcepoint Security Lab, Jaff ransomware, written in C programming language, is being distributed with the help of Necurs botnet that currently controls over 6 million infected computers worldwide. Necurs botnet is sending emails to millions of users with an attached PDF document, which if clicked, opens up an embedded Word document with a malicious macro script to downloads and execute the Jaff ransomware, Malwarebytes says . Jaff is Spreading at the Rate of 5 Million per Hour The malicious email camp...
