Kasseika Ransomware Resurrects BlackMatter’s Terror with Antivirus Disguise

Ransomware’s new trick? Kasseika malware cosplays antivirus, slaying real security like a Trojan Horse at a digital toga party. It’s asking for a 50 Bitcoin score, or the encryption stays. Call it BlackMatter’s zombie comeback—because malware never really dies, it just gets a ghoulish reboot.

Hot Take:

Just when you thought it was safe to go back into the digital waters, a ne’er-do-well ransomware named Kasseika throws on a fake antivirus costume and starts playing whack-a-mole with your actual security software. This cyber-shenanigan is like the horror movie villain that just won’t stay dead, rising from the ashes of BlackMatter like a malware phoenix… or should I say, a malware martini, shaken and definitely stirred.

Key Points:

  • Kasseika, the malware in sheep’s clothing, is fooling computers into thinking it’s an antivirus, then it’s lights out for real security programs.
  • It kicks off its digital destruction derby with a phishing email—classic bait and switch—to snatch those precious login details.
  • The malware’s MVP is Martini.sys, an outdated driver that’s the skeleton key to shutting down 991 (!) security-related processes.
  • After the security slaughter, Kasseika encrypts and asks for a ransom of 50 Bitcoin, with a late fee that would make your bank blush.
  • Experts at Trend Micro are having déjà vu, seeing striking similarities between Kasseika and the BlackMatter ransomware of yesteryears.

Martini on the Rocks, Hold the Security

Imagine a digital world where your trusted antivirus turns against you, morphing into the very threat it's supposed to protect you from. That's Kasseika for you, a ransomware that's gone undercover as an antivirus program. Its modus operandi? A phishing email that's the equivalent of saying, "Psst, wanna see something cool?" only to swipe your login creds when you're not looking.

Driver's Ed for Cybercriminals: Martini.sys 101

Next up, Kasseika brings out the secret weapon—Martini.sys. This driver may sound like it's fresh out of a Bond movie, but it's really an antiquated piece of software that Kasseika uses to go full terminator on your genuine security software. With a kill list longer than a CVS receipt, it stops 991 processes in their tracks, ensuring your computer's as vulnerable as a turtle without its shell.

Bitcoin or Bust

Once the coast is clear (and by clear, I mean your cyber defenses are as useful as a chocolate teapot), Kasseika gets down to business encrypting your files. Then, in true ransomware fashion, it leaves a note with a demand for 50 Bitcoin, because apparently, even malware has an expensive taste these days. And if you're a procrastinator, beware—the price goes up faster than a bid on a rare Beanie Baby on eBay.

Like a Bad Penny, BlackMatter Turns Up

Trend Micro's cyber-sleuths are scratching their heads because Kasseika's got a familiar MO, one that reeks of BlackMatter, a ransomware variant that supposedly bit the dust in 2021. But with no source code in sight, the question remains: Is Kasseika the original gangster's prodigal son, or did someone take a shopping trip on the dark web to snap up BlackMatter's DNA?
