NCC Warns Telecom Operators On 'ransomware' Cyber-attack by zubbie01(m): 10:13pm On May 17, 2017
Ransomware is a type of malicious software that carries out the cryptoviral extortion attack from cryptovirology that blocks access to data until a ransom is paid and displays a message requesting payment to unlock it. Simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse. More advanced malware encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. The ransomware may also encrypt the computer's Master File Table (MFT) or the entire hard drive.Thus, ransomware is a denial-of-access attack that prevents computer users from accessing files since it is intractable to decrypt the files without the decryption key. Ransomware attacks are typically carried out using a Trojan that has a payload disguised as a legitimate file.

Ransom: A hacker's way to get paid
Ransomware in figures :
Every 10 seconds someone in the world is hit by ransomware
$1 billion was extorted from ransomware victims in 2016. The threat is growing! In 2015 the total was $50 million. $500 is the average ransoms payment, but can exceed $10,000
While initially popular in Russia, the use of ransomware scams has grown internationally
Infection with one wrong click
Ransomware infects a computer and encrypts all the data on its storage drives while spreading to any other vulnerable computer that are connected. How can a computer become infected? Links and attachments in spam emails. Cyber criminals use clever social engineering tricks to make you click malicious links or attachments included in a spam email.
Malicious websites
With a “drive-by download,” you only need to visit a site or click on a banner to download the malicious software to your computer.
Video Games
Gamers are targeted through saved-game content and downloadable “extras” that drop the malware on their computer.
Antivirus software can fail to detect ransomware infections. Cybercriminals frequently design their malicious code to avoid discovery by researching known anti-malware solutions in order to identify weaknesses in the detection technologies or the program architecture.

The Nigerian Communications Commission (NCC) yesterday alerted all operators and their respective subscribers to the outbreak of Ransomware.
"This situation demands that proactive measures be taken by all players in the telecommunication eco-system to forestall the hazards of critical data loss, financial losses and ultimately network/business disruption."
The Commission urged Nigerians, as protective measures to among others; obtain software patch released by Microsoft in March 2017 to fix the Ransomware Virus; plan scheduled penetration tests on the networks and systems to ensure protection and availability at all times.
The Commission urged subscribers who use their smartphones as substitutes to computers for Internet access to protect themselves and their devices by not opening e-mail attachments/links from unknown sources; not clicking pop-ups and applets on unknown websites and installing effective antivirus software for their mobile devices.
