Computer viruses can cause significant harm to your devises. Hackers, spammers and those plotting cyberattacks date back to the start of computing. Over time, several viruses have been particularly damaging. Here are the three worst computer viruses of all time:
Malware researchers have released a tool that can decrypt files affected by the new threat
Understanding how to buy bitcoins and pay ransomware authors for decryption keys is hard enough, yet some cybercriminals now expect their victims to do it in under an hour if they want all of their files back.
A new ransomware program dubbed Jigsaw encrypts users' files and then begins to progressively delete them until the victim pays the equivalent of $150 in Bitcoin cryptocurrency.
As more US companies snuff out point of sale malware by deploying chip-and-PIN bankcard technology, attackers are rushing to exploit existing magnetic strip card systems still vulnerable to malware. A group of hackers that go by the name Bears Inc. are behind the latest barrage of attacks with a custom-built point of sale malware called Treasurehunt, according to research from FireEye.
The FBI is seeking help from US firms as it investigates a nasty strain of ransomware, Reuters reports.
Ransomware encrypts data on infected machines and then asks for money before restoring access to information.
The FBI is analysing a strain of ransomware called MSIL/Samas that tries to encrypt data across entire networks rather than single computers.
Malicious software can steal your personal information and, sometimes, your cash. But it can also entertain and amuse—in hindsight, at least.
The Internet Archive has launched the Malware Museum, a collection of programs—mostly viruses—distributed on home computers in the 1980s and '90s. "Once they infected a system, they would sometimes show animation or messages that you had been infected," the website's description said, so if that's your thing, check it out.
