Beware: Cyber Security Attacks
Cyber attacks and security breaches are showing no signs of slowing down. In a matter of a few days, we see the cyber thefts taking place in biggest corporations that extend to loss of data, personal records and financial information. Cybercriminals have become more active than ever and unfortunately are becoming more widespread and destructive.
The crux of the matter is, without sufficient security procedures and controls, businesses are highly exposed and vulnerable to a pervasive attack. Primarily, there are two types of attacks: Active and Passive. Active attacks are those where important information is being watched, while passive attacks are those where cybercriminals modify the information in order to corrupt or destruct it.
Here are some of the most common and dangerous cyber attacks which businesses and individuals must be aware of:
Trojans are the most common and widespread means of attacking a computer or system. Many times, an online user is prompted to run a Trojan on a trusted website. This occurs because the website itself is a victim of a hacker. By and large, infected websites tell a user that they have been intruded by viruses and its essential to run ‘fake’ anti-virus software, which itself is a virus. At other instances, websites show pop-ups indicating that the system is running out of space and it needs ‘forged’ defragmentation. To cope with the ‘intended’ virus attack, they ask you to download a sham Adobe Reader or any other equally renowned software program.
In reality, countless socially-engineered Trojans have impacted your system. The best solution against this threat is having adequate end-user education; furthermore, trusted anti-virus software can also work effectively in this case.
According to an astounding statistic, as much as 70% of the email that you receive is spam. Thanks to the efforts of anti-spamming vendors, we somehow manage to achieve a clean inbox. Despite all, almost everyone receives 3-5 spam emails each day, out of which few are phishing mock-ups of genuine e-mails. Phishing emails are a vicious, corrupted web spread around by hackers. They look all good from the outside and even warns the user about falling for deceitful emails. However, what causes you to get stuck in the ferocious web is the devious link that solicits for personal information.
Again, a thorough end-user education is something that’s needed the most to counteract this menace. You can also make use of some effective anti-phishing tools that keep your emails and system protected.
If you’re thinking that viruses aren’t that harmful and adverse, then brace their cousins ‘network-travelling worms’. Conficker and Zeus are two of the most common and damaging network worms that have unfavorably impacted big and small organizations. They are much more severe and ruthless than viruses present in ordinary emails. Network worms are worse in the sense that they disguise themselves and cause damage secretively. The Conficker worm will try to abuse network shares by logging in using a series of bad passwords such as abcd, 1234, password 1 etc.
Some important ways of preventing network worms are jamming implementable emails, enhancing patching, immobilizing autoruns and setting unbeatable password policies.
