- Greediest Trojan targeting banks
Trojan-Spy.Win32.Banker.lax, which targets customers of 104 banks, wins this category in April
- Greediest Trojan targeting payment systems
Another variant of Banker, in this case Trojan-Spy.Win32.Banker.krv takes the palm this month. It targets the users of three e-payment systems.
- Greediest malicious program targeting payment cards
April’s winner in this category is Trojan-Spy.Win32.Bancos.blc, which has its sights set on three payment card systems at once.
- Stealthiest malicious program
This month, one variant of Backdoor.Win32.Hupigon.bqsi wins out, being packed with seven different packers.
- Smallest malicious program
The tiny Trojan.BAT.MouseDisable.b, with a mere 22 bytes, still manages once launched to block the mouse.
- Largest malicious program
April’s winner is Trojan-Dropper.Win32.Agent.nrh – at 46MB in size, it’s not that large compared to previous victors in this category
- Most malicious program
There’s a new entrant in this category – a modification of Backdoor.Win32.Agobot.gen replaces the Haradong family which has ruled for the last two months. Malicious programs from this family search for and destroy antivirus solutions in all possible locations – in RAM, the system registry and on disk.
- Most common malicious program in email traffic
In a couple of months we may have to reconsider the value of this category, as it’s been almost exclusively occupied by Email-Worm.Win32.Netsky.q. The worm isn’t conceding ground to any other malicious program, and during the last month it’s even increased its share of infected mail traffic to 40.58%.
- Most common Trojan family
Backdoor.Win32.Hupigon remains the most ‘fertile’ malicious program, giving birth to 3151 modifications in the course of a single month – only slightly fewer than last month.
- Most common virus/ worm family
Worm.Win32.AutoRun heads this category in April, with 230 new modifications.
