This post was originally published on this siteThe U.S. government is warning that “smart locks” securing entry to an estimated 50,000 dwellings nationwide contain hard-coded credentials that can be used to remotely open any of the locks. The lock’s maker Chirp Systems remains unresponsive, even though it was first notified about the critical weakness in March 2021. Meanwhile, Chirp’s parent company, RealPage, Inc., is being sued by multiple U.S. states for allegedly colluding with landlords to illegally raise rents. On March 7, 2024, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) warned about a remotely exploitable vulnerability with “low attack […]

This post was originally published on this siteOn April 9, Twitter/X began automatically modifying links that mention “twitter.com” to read “x.com” instead. But over the past 48 hours, dozens of new domain names have been registered that demonstrate how this change could be used to craft convincing phishing links — such as fedetwitter[.]com, which until very recently rendered as fedex.com in tweets.

This post was originally published on this siteIf only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software. Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure […]

This post was originally published on this siteThread hijacking attacks. They happen when someone you know has their email account compromised, and you are suddenly dropped into an existing conversation between the sender and someone else. These missives draw on the recipient’s natural curiosity about being copied on a private discussion, which is modified to include a malicious link or attachment. Here’s the story of a recent thread hijacking attack in which a journalist was copied on a phishing email from the unwilling subject of a recent scoop. In Sept. 2023, the Pennsylvania news outlet LancasterOnline.com published a story about […]

This post was originally published on this siteSeveral Apple customers recently reported being targeted in elaborate phishing attacks that involve what appears to be a bug in Apple’s password reset feature. In this scenario, a target’s Apple devices are forced to display dozens of system-level prompts that prevent the devices from being used until the recipient responds “Allow” or “Don’t Allow” to each prompt. Assuming the user manages not to fat-finger the wrong button on the umpteenth password reset request, the scammers will then call the victim while spoofing Apple support in the caller ID, saying the user’s account is […]

This post was originally published on this siteBorrowing from the playbook of ransomware purveyors, the darknet narcotics bazaar Incognito Market has begun extorting all of its vendors and buyers, threatening to publish cryptocurrency transaction and chat records of users who refuse to pay a fee ranging from $100 to $20,000. The bold mass extortion attempt comes just days after Incognito Market administrators reportedly pulled an “exit scam” that left users unable to withdraw millions of dollars worth of funds from the platform. An extortion message currently on the Incognito Market homepage. In the past 24 hours, the homepage for the […]

This post was originally published on this siteThere are indications that U.S. healthcare giant Change Healthcare has made a $22 million extortion payment to the infamous BlackCat ransomware group (a.k.a. “ALPHV“) as the company struggles to bring services back online amid a cyberattack that has disrupted prescription drug services nationwide for weeks. However, the cybercriminal who claims to have given BlackCat access to Change’s network says the crime gang cheated them out of their share of the ransom, and that they still have the sensitive data Change reportedly paid the group to destroy. Meanwhile, the affiliate’s disclosure appears to have […]

This post was originally published on this siteThe ransomware group LockBit told officials with Fulton County, Ga. they could expect to see their internal documents published online this morning unless the county paid a ransom demand. LockBit removed Fulton County’s listing from its victim shaming website this morning, claiming the county had paid. But county officials said they did not pay, nor did anyone make payment on their behalf. Security experts say LockBit was likely bluffing and probably lost most of the data when the gang’s servers were seized this month by U.S. and U.K. law enforcement. The LockBit website […]

This post was originally published on this siteThe FBI’s takedown of the LockBit ransomware group last week came as LockBit was preparing to release sensitive data stolen from government computer systems in Fulton County, Ga. But LockBit is now regrouping, and the gang says it will publish the stolen Fulton County data on March 2 unless paid a ransom. LockBit claims the cache includes documents tied to the county’s ongoing criminal prosecution of former President Trump, but court watchers say teaser documents published by the crime gang suggest a total leak of the Fulton County data could put lives at […]

This post was originally published on this siteU.S. and U.K. authorities have seized the darknet websites run by LockBit, a prolific and destructive ransomware group that has claimed more than 2,000 victims worldwide and extorted over $120 million in payments. Instead of listing data stolen from ransomware victims who didn’t pay, LockBit’s victim shaming website now offers free recovery tools, as well as news about arrests and criminal charges involving LockBit affiliates. Investigators used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools. Dubbed “Operation Cronos,” the law enforcement action involved the seizure […]

Sunnyvale, Calif. based Juniper Networks makes high-powered Internet routers and switches, and its products are used in some of the world’s largest organizations.

The leaked user database shows one of the forum’s founders was an attorney who advised Russia’s top hackers on the legal risks of their work, and what to do if they got caught.

Launched in 2001 under the tagline “Network terrorism,” Mazafaka would evolve into one of […]
