Phishing campaigns delivering malware families such as DarkGate and PikaBot are following the same tactics previously used in attacks leveraging the now-defunct QakBot trojan. "These include hijacked email threads as the initial infection, URLs with unique patterns that limit user access, and an infection chain nearly identical to what we have seen with QakBot delivery," Cofense  said  in a report shared with The Hacker News. "The malware families used also follow suit to what we would expect QakBot affiliates to use." QakBot, also called QBot and Pinkslipbot, was  shut down  as part of a coordinated law enforcement effort codenamed Operation Duck Hunt earlier this August. The use of DarkGate and PikaBot in these campaigns is not surprising as they can both act as conduits to deliver additional payloads to compromised hosts, making them both an attractive option for cybercriminals. PikaBot's parallels to QakBot were  previously highlighted  by Zscale...

A novel class of vulnerabilities could be leveraged by threat actors to inject visually deceptive malware in a way that's semantically permissible but alters the logic defined by the source code, effectively opening the door to more first-party and supply chain risks. Dubbed " Trojan Source attacks ," the technique "exploits subtleties in text-encoding standards such as  Unicode  to produce source code whose tokens are logically encoded in a different order from the one in which they are displayed, leading to vulnerabilities that cannot be perceived directly by human code reviewers," Cambridge University researchers Nicholas Boucher and Ross Anderson said in a newly published paper. The  vulnerabilities  — tracked as CVE-2021-42574 and CVE-2021-42694 — affect compilers of all popular programming languages such as C, C++, C#, JavaScript, Java, Rust, Go, and Python. Compilers are programs that translate high-level human-readable source code into their lower-l...

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...

Your mailbox may be filling up with Christmas cards from friends and family, and so might your email inbox. But, as the song says, 'you better watch out,' because some of those merry emails could be from an internet Grinch looking to steal your peace of mind. Christmas cards are a great way to send holiday wishes to those you love. However, many of us are opting to send our cards electronically using e-cards. "One of the big problems around Christmastime is everyone sends out Christmas cards. That's great, and it's great to see one in your email inbox. The problem is, about half of them that you're going to get are actually links to viruses and Trojan horses that will infect your computer," explained News 4 WOAI Web Expert Bob Gambert. Some of these malicious emails will attack your email address book and flood your friends' inboxes with spam. So, how do you know which e-card is safe to open? Our computer expert says don't open any of them. Inst...
