Nasty Malware

CryptoLocker, a new and nasty piece of malicious software is infecting computers around the world – encrypting important files and demanding a ransom to unlock them. According to Sophos, the worldwide digital security company, it’s been hitting pretty hard for the past six weeks or so.

“It systematically hunts down every one of your personal files – documents, databases, spreadsheets, photos, videos, and music collections – and encrypts them with military-grade encryption and only the crooks can open it,” said Chester Wisniewski, a senior security advisor at Sophos.

Even though it’s infected, your computer keeps working normally; you just can’t access any of your personal files. It’s scary, especially if you haven’t backed up your data.Read More

RATSNIFF

The new trojan, known as Ratsnif, is used by OceanLotus, a known cybercriminal ring linked to Vietnam’s espionage efforts. Also known as APT32, CobaltKitty, SeaLotus, and APT-C-00 in the infosec community, the hackers typically combine unique malware with commercially-available tools, like Cobalt Strike.Ratsnif is a remote access trojan used in cyber-espionage campaigns from the OceanLotus group. A remote shell can be set up and served for ARP poisoning (to route traffic through the Ratsnif), DNS spoofing, and HTTP direction. It has the ability to modify web pages and SSL hijacking. It has a configuration file to make features more efficient: HTTP injection, protocol parsing, and SSL hijacking with separately supplied SSL certificates.Read More

Timebomb

In computer software, a time bomb is part of a computer program that has been written so that it will start or stop functioning after a predetermined date or time is reached. A malicious program that is programmed to “detonate” at a specific time and release a virus onto the computer system or network. The term “time bomb” does not refer to a program that stops functioning a specific number of days after it is installed; instead, the term “trialware” applies. Time bombs are commonly used in beta (pre-release) software when the manufacturer of the software does not want the beta version being used after the final release date.Read More

ADWARE

Adware is unwanted software designed to throw advertisements up on your screen, most often within a web browser. Some security professionals view it as the forerunner of the modern-day PUP (potentially unwanted program). Typically, it uses an underhanded method to either disguise itself as legitimate, or piggyback on another program to trick you into installing it on your PC, tablet, or mobile device.Read More
