Microsoft is warning Azure cloud users that a Chinese controlled botnet is engaging in “highly evasive” password spraying. Not sure about the “highly evasive” part; the techniques seem basically what you get in a distributed password-guessing attack: “Any threat actor using the CovertNetwork-1658 infrastructure could conduct password spraying campaigns …

Enlarge (credit: Aurich Lawson / Ars Technica ) Cybercriminals and spies working for nation-states are surreptitiously coexisting inside compromised name-brand routers as they use the devices to disguise attacks motivated both by financial gain and strategic espionage, researchers said. In some cases, the coexistence is peaceful, as financially motivated hackers provide …

The widely reported story last week that 1.5 million smart toothbrushes were hacked and used in a DDoS attack is false. Near as I can tell, a German reporter talking to someone at Fortinet got it wrong, and then everyone else ran with it without reading the German …

Interesting story of an Apple Macintosh app that went rogue. Basically, it was a good app until one particular update...when it went bad. With more official macOS features added in 2021 that enabled the “Night Shift” dark mode, the NightOwl app was left forlorn and forgotten on many …
Genesis Market is shut down : Active since 2018, Genesis Market’s slogan was, “Our store sells bots with logs, cookies, and their real fingerprints.” Customers could search for infected systems with a variety of options, including by Internet address or by specific domain names associated with stolen credentials.

Security researchers found a software bug in the KmsdBot cryptomining botnet: With no error-checking built in, sending KmsdBot a malformed command—like its controllers did one day while Akamai was watching—created a panic crash with an “index out of range” error. Because there’s no persistence, the bot …
Mandiant is reporting on a new botnet. The group, which security firm Mandiant is calling UNC3524, has spent the past 18 months burrowing into victims’ networks with unusual stealth.

Google took steps to shut down the Glupteba botnet, at least for now. (The botnet uses the bitcoin blockchain as a backup command-and-control mechanism, making it hard to get rid of it permanently.) So Google is also suing the botnet’s operators. It’s an interesting strategy. Let’s …

Security researchers have recently discovered a botnet with a novel defense against takedowns. Normally, authorities can disable a botnet by taking over its command-and-control server. With nowhere to go for instructions, the botnet is rendered useless. But over the years, botnet designers have come up with ways to make …
A coordinated effort has captured the command-and-control servers of the Emotet botnet: Emotet establishes a backdoor onto Windows computer systems via automated phishing emails that distribute Word documents compromised with malware. Subjects of emails and documents in Emotet campaigns are regularly altered to provide the best chance of luring …
