HDDCryptor Ransomware Returns And Now Encrypts Entire Hard Drives
The newest surge in ransomware is drawing concern for its ability to encrypt entire hard drives. HDDCryptor, or Mamba, targets network resources such as folders, drives, files, serial ports and printers and then locks down the drive.
Point of Sale malware, designed to lift bank card details (and other information too) from payment terminals around the world, continues to evolve and to propagate. In February of this year our researchers noted the evolution several malware families.
Think changing your Yahoo password is enough? Think again…
With the recent announcement of more than 500 million accounts impacted by a security breach, many Yahoo users have been changing their passwords. After all, that’s the official guidance. However, as ZDI’s Simon Zuckerbraun points out, a new password isn’t enough.
As early as March 2016, we noticed that Encryptor RaaS’s developer exerted great effort to make it ‘fully undetectable.’ This included signing the ransomware with valid certificates, as well as frequently using counter-AV services and crypters. Four months after, however, the service abruptly closed up shop.
Using Pagers in Healthcare Has Become a Data Protection Hazard
Pagers are still in use today, especially in healthcare. But while it can make sense to still use pagers in healthcare, it is still an older technology. And as is so often the case with older technologies, it can lack the appropriate countermeasures to keep it safe in today’s threat environment.
Cloud Computing Company OVH Was Hit by Largest DDoS Attack Ever Reported
Last week, French cloud computing company OVH was hit with Distributed Denial of Service attacks that exceeded one terabit per second, the Hacker News reported, which it notes is the “largest DDoS attack ever reported.” The founder of the company, Octave Klaba, tweeted a screenshot of the two simultaneous DDoS attacks, revealing multiple attacks surpassing 100 gigabits per second and one alone hitting 799 gigabits per second.
Yahoo Breach Could Affect Credit Cards
Credit card accounts probably won’t be affected. But “probably” is not “certainly.” If you tend to reuse passwords across multiple sites, now’s the time to stop, and to change those passwords. And Yahoo is still encouraging people to check their credit reports.
Jive Resets Passwords After August Data Breach
Software house Jive has reset customers’ passwords after the company discovered a data breach. The company said in a notification letter to the state’s attorney general on Friday — released this week — that some email addresses and passwords had been accessed by an outsider.
Yahoo Is Facing Lawsuits in the Wake of Massive Data Breach
Yahoo is facing lawsuits from people who fear their accounts have been hacked and claim the company was “grossly negligent,” putting their financial and personal data at risk. Two lawsuits, both filed in California, also allege that Yahoo did not adequately disclose the breach that exposed private information of at least 500 million users.
Smart Home Devices Were Used in Cyberattack on Tech Writer’s Site
From smart thermostats to smart door locks, the so-called “internet of things” promises convenience. But security researchers warn that “smart” devices could also be used as cyberweapons. That was illustrated recently when an army of hacked consumer electronics was used in a high-profile cyberattack.
Teenager Appears in Court Over TalkTalk Cyberattack
Daniel Kelley, 19, appeared at Westminster magistrates court on Tuesday accused of demanding 465 bitcoins, worth about £216,000, from the company after allegedly carrying out a cyber-attack on its website in October last year.
